ABSTRACT
Introduction: Adjuvant anti-cancer systemic therapy (SACT) following lung resection improves overall survival in stage II/II non-small cell lung cancer (NSCLC). The Getting It Right First Time (GIRFT) National Specialty Report for Lung Cancer recommends centres publish adjuvant SACT rates for National benchmarking and proposes a target of >40% of eligible patients undergo SACT. We report a regional audit into the uptake of adjuvant SACT in Greater Manchester (GM). Method(s): A retrospective case review of all patients undergoing curative-intent NSCLC surgery with a pathological stage of II/III from 01/01/21 to 30/04/21. Data collected included patient demographics, uptake of adjuvant SACT, reasons for no adjuvant SACT and tolerance and complications of SACT. Result(s): 58 patients underwent surgical resection within the audit period and were eligible for adjuvant SACT. Median age was 70 years (range 45 - 81) and 60% were female. 47% (27/58) commenced adjuvant SACT;41% (24/58) were treated with chemotherapy and 7% (4/58) were treated with tyrosine kinase inhibitors. 58% (14/24) of patients that commenced adjuvant chemotherapy completed 4 cycles. Carboplatin/Vinorelbine was the commonest regimen (82%, 18/22). There were no grade III-V complications and no chemotherapy-related deaths. Dose reduction due to toxicity was required in 14% (3/22). The reasons adjuvant systemic therapy was not given were patient choice in 32% (10/31), poor physical health such that risks outweighed benefits in 42% (13/31), and other reasons (e.g. need to treat synchronous primary tumours) in 26% (8/31). COVID-19 was not recorded as a cause for adjuvant omission/ dose reduction. Conclusion(s): This data provides national benchmarking information for adjuvant SACT in NSCLC and suggests the target of >40% is achievable and appropriate. Interventions that improve patient fitness pre- and post-operatively might increase adjuvant SACT uptake. This regional audit will be extended to review all eligible patients in 2021 and further data will be presented. Disclosure: No significant relationships.Copyright © 2023 Elsevier B.V.
ABSTRACT
Introduction: The COVID-19 pandemic has imposed a large burden on our global medical systems, particularly in patients that would require emergency surgery. Method(s): This single centre study determined the perioperative outcomes of patients who underwent emergency surgery before and during the COVID-19 pandemic after using a propensity score matching analysis. Result(s): A decrease in the number of emergency surgeries performed during the pandemic was noted at 47.9%. Data showed that severe complications arose more frequently during the pandemic (pvalue<0.05). Furthermore, it arose more frequently in patients who had a concomitant COVID-19 infection. Age was directly proportional to the likelihood of developing of severe postoperative complications (pvalue<0.05). Undergoing cancer surgery and being classified as ASA IV increased the likelihood of developing severe postoperative complications (pvalue<0.05). Preoperative time was a significant factor for patients who underwent trauma and can- cer surgery during the pandemic since it was noted to be directly proportional to the likelihood of developing severe postoperative complications (pvalue<0.05). The mortality rate was significantly pronounced during the pandemic for patients who underwent benign and trauma surgeries (pvalue<0.05). Conclusion(s): Severe complications arose more frequently during the pandemic. Undergoing cancer surgery and being classified as ASA IV increased the likelihood of developing of severe postoperative complications. Age and Preoperative time were noted to be directly proportional to the development of severe postoperative complications particularly in trauma and cancer surgeries. The mortality rate was significantly more pronounced during the pandemic for patients who underwent benign and trauma surgeries especially with longer preoperative time.
ABSTRACT
Introduction: Croatian National Cancer Registry of Croatian Institute for Public Health reported that in year 2020 lung cancer was the second most common cancer site diagnosed in men with 16% and the third most common in women with 10% incidence among all cancer sites. Unfortunatelly lung cancer has the highest mortality in both men and women. Haematological malignancies had 7% share in all malignancies in both male and female cances cases. In 2020 190 newly diagnosed cases of lymphatic leukemia in men and 128 cases in women were reporeted, meaning 1.5 and 1.2% of all malignancies, respectively. Chronic lymphatic leukemia (CLL) is an advanced age disease and incidence increases with age. Impaired immunity, T and B cell dysfunction in CLL, chromosomal aberations, long-term immunosuppressive therapy and genetic factors can all cause secondary malignancies. Co- occurence of solid tumors and CLL is very rare. Although patiens with CLL have an increased risk of developing second primary malignancies including lung carcinoma, the data about their clinical outcomes are lacking. Parekh et al. retrospectively analyzed patients with simultaneous CLL and lung carcinoma over a 20-year period, and they found that ~2% of patients with CLL actually developed lung carcinoma. The authors claimed that up to 38% of patients will also develop a third neoplasm more likely of the skin (melanoma and basal cell carcinoma), larynx (laryngeal carcinoma) or colon. Currently there are no specific guidelines for concurrent CLL and non-small cell lung carcinoma (NSCLC) treatment. Usually, when the tumors are diagnosed simultaneously, treatment is based to target the most aggressive malignancy, as the clinical outcomes depend on the response of the tumor with the poorest prognosis. For this reason, a multidisciplinary approach is mandatory. Case report: A patient with history of coronary heart disease, myocardial infarction and paroxysmal atrial fibrillation was diagnosed in 2019 (at the age of 71) with B chronic lymphocytic leukemia with bulky tumor (inguinal lymph nodes 8x5 cm), stage B according to Binet, intermediate risk. He was treated with 6 cycles of chemoimmunotherapy (rituximab/cyclofosfamid/fludarabine). In 10/2019 remission was confirmed, but MSCT described tumor in the posterior segment of upper right lung lobe measuring 20x17 mm and bilateral metastases up to 11 mm. Bronchoscopy and biopsy were performed, and EGFR neg, ALK neg, ROS 1 neg, PD-L1>50% adenocarcinoma was confirmed. He was referred to Clinical Hospital Center Osijek where monotherapy with pembrolizumab in a standard dose of 200 mg intravenously was started in 01/2020. Partial remission was confirmed in October 2020. Immunotherapy was discontinued due to development of pneumonitis, dysphagia and severe weight loss (20kg), but without radiologically confirmed disease progression. At that time he was referred to our hospital for further treatment. Gastroscopy has shown erosive gastritis with active duodenal ulcus, Forrest III. Supportive therapy and proton pump inhibitor were introduced. After complete regression of pneumonitis, improvement of general condition and resolution of dysphagia, no signs of lung cancer progression were found and pembrolizumab was reintroduced in 12/2021. Hypothyroidism was diagnosed in 01/2021 and levothyroxine replacement ther apy was started. In 03/2021 he underwent surgical removal of basal cell carcinoma of skin on the right temporal region with lobe reconstruction. From 02/2021, when pembrolizumab was reintroduced, regression in tumor size was continously confirmed with complete recovery of general condition. He was hospitalized for COVID 19 infection in 09/2021, and due to complications pembrolizumab was discontinued till 11/2021. Lung cancer immunotherapy proceeded till 11/2022, when Multidisciplinary team decided to finish pembrolizumab because of CLL relapse. CLL was in remission till August 2022 when due to B symptoms, lymphcytosis, anemia and generalized lymphadenopathy, hematological workup including biopsy of cervical lymph node was performed and CLL/SLL relapse was confirmed. Initially chlorambucil was introduced, but disease was refractory. Based on cytogenetic test results (IGHV unmutated, negative TP53) and due to cardiovascular comorbidity (contraindication for BTK inhibitors) venetoclax and rituximab were started in 01/2023. After just 1 cycle of treatment normal blood count as well as regression of B symptoms and peripheral lymphadenopathy occured, indicating the probability of complete disease remission. In our patient with metastatic lung adenocarcinoma excellent disease control is achieved during 41 month of treatment in first line setting. Furthermore, relapsed/refractory CLL/SLL is currently in confirmed remission. Conclusion(s): Successful treatment of patients with multiple primary malignancies is based on multidisciplinarity, early recognition and management of side effects, treatment of comorbidities with the aim of prolonging life, controlling symptoms of disease and preserving quality of life.
ABSTRACT
Background: During the coronavirus disease 2019 (COVID-19) pandemic, established best practices in cancer care were modified to diminish the risk of COVID-19 infection among patients and health-care workers. Objective(s): We aimed to study the modifications in cancer-directed therapy during the first wave of the COVID-19 pandemic. Material(s) and Method(s): A cross-sectional study of patients with cancers of the head and neck, thoracic, urologic, and central nervous systems who visited the medical oncology department of the Tata Memorial Hospital, Mumbai, India, between April 22, 2020 and June 01, 2020, was conducted. Data were prospectively collected in an online pro forma and supplemented from the electronic medical records. Result(s): Of a total of 514 patients, 363 (71%) were men. The most common malignancy was lung cancer in 234 patients (46%). Cancer-directed therapy was modified in 83 patients (16%). Deviations consisted of modification of the chemotherapy regimen (48%), temporary discontinuation of chemotherapy in 37%, and interim chemotherapy to delay surgery in 5%. Changes in the chemotherapy regimen included a shift to a less intensive regimen in 45%, changing from intravenous to oral in 40%, and less frequent dosing of immunotherapy in 7%. Considering missed appointments as a deviation from planned cancer therapy, 68% of patients had a deviation in the standard planned cancer care. Conclusion(s): Almost two-thirds of the patients could not reach the hospital during the COVID-19 pandemic lockdown in India. Of those who could reach the hospital, one of out every six patients with cancer had a change in their cancer-directed treatment, half of which consisted of a modification in the standard chemotherapy regimens. The effects of these therapy deviations are likely to be long-lasting.

ABSTRACT
Introduction: Surgical treatment of rectal cancer depends on clinical stage, size and location of primary tumor. A sphincter preserving technique such as low anterior resection (LAR) is the preferred method if negative distal margin can be achieved. If an adequate distal margin cannot be obtained, an abdominoperineal resection (APR) is required. A proctosigmoidectomy (Hartmann's procedure) is performed in patients with potentially curable obstructing rectal cancer after neoadjuvant chemoradiotherapy, or as a palliative treatment for locally advanced rectal cancer. Aim(s): The aim of this retrospective study was to investigate the impact of COVID 19 pandemic on the number and type of surgeries performed for the treatment of rectal cancer in UHC Zagreb, Department of Surgery. Material(s) and Method(s): Collected data were extracted from medical records of the patients who underwent surgery at the Department of Surgery from 1st of January 2016 to 31st of December 2022 with prior Ethics Committee approval. Total of 688 patients were included. Retrospective analysis of number and type of surgery was done consecutively by years for the period of interest. Result(s): In 2016 total of 75 patients underwent elective surgery for rectal cancer. LAR was performed in 64% (N=48) of patients, Hartmann's procedure in 20% (N=15), and APR in 16% (N=12). In 2017, 94 surgeries were performed. LAR accounted for 64% (N=60), Hartmann's procedure 17% (N=16), and APR 19% (N=18). In 2018, 115 surgeries were performed. LAR accounted for 69% (N=79), Hartmann's procedure 10% (N=12), and APR 21% (N=24). In 2019, 80 surgeries were performed. LAR accounted for 67% (N=54), Hartmann's procedure 9% (N=80), and APR 24%. In 2020, 78 surgeries were performed. LAR accounted for 59% (N=46), Hartmann's procedure 14% (N=11), and APR 27% (N=21). In 2021, 124 surgeries were performed. LAR accounted for 66% (N=82), Hartmann's procedure 14% (N=17), and APR 20% (N=25). In 2022, 122 surgeries were performed. LAR accounted for 64% (N=78), Hartmann's procedure 15% (N=18), and APR 21% (N=26). Conclusion(s): Our results show steady growth in numbers of performed surgeries in the years prior to the pandemic, with exception of the year 2019 when our department underwent organizational changes. In 2020, significant decrease in number of surgeries was observed as a result of restrictive epidemiological measures established to reduce the spread of COVID 19 infection. COVID 19 pandemic measures also resulted in delayed diagnosis and treatment of rectal cancer which is indirectly shown through the increasing share of Hartmann's procedure. In the years following the relaxation of measures, significant increase in number of performed surgeries that exceeded all the pre-pandemic years was recorded. Constant elevated share of Hartmann's procedure was noted as possible consequence of post COVID delay in diagnosis and confirmation of rectal cancer in more advanced stages of disease.
ABSTRACT
Background: Patients with non-small cell lung cancer (NSCLC) treated with adjuvant vinorelbine-platinum chemotherapy experience neutropenia, which may lead to early termination of treatment. However, evidence suggests that survival is superior in patients who complete four cycles of chemotherapy [1]. Granulocyte colony stimulating factor (GCSF) prophylaxis is used to prevent neutropenia. During the COVID pandemic, the threshold for initiating prophylaxis was lowered to reduce need for hospital attendance with the concomitant risk of hospital-acquired infection [2]. We evaluated whether GCSF prophylaxis supported completion of chemotherapy in patients treated at St Bartholomew's Hospital. Method(s): Data was retrospectively collected on the 112 patients with NSCLC who received adjuvant vinorelbine-platinum chemotherapy (total 349 cycles) in the period Jan 2017- Jul 2022. GCSF prophylaxis was prescribed at physician discretion. chi2 tests were carried out using SPSS 28. Result(s): A significantly higher proportion of patients who received GCSF prophylaxis completed four cycles of chemotherapy (chi2=5.120, p=0.024). These patients also experienced a lower incidence of grade 3 or 4 neutropenia (chi2=6.801, p=0.009). Over 5 years, 2/112 (1.75%) patients died, both from neutropenic sepsis;neither of these patients received prophylactic GCSF. GCSF prophylaxis was not associated with increase in the incidence of thromboembolic events (chi2=1.462, p=0.442). Conclusion(s): GCSF is safe and effective as primary prophylaxis in NSCLC patients receiving adjuvant chemotherapy. Use of GCSF will reduce proportion of post-operative patients considered too high risk for chemotherapy due to concerns about neutropenia. Disclosure: No significant relationships.

ABSTRACT
Introduction: Lung cancer is third most common cancer and highest cause of cancer death in the UK. COPD and smoking are known cancer risk factors so early intervention is essential. Incidence is higher in areas of deprivation where early presentation is less likely and outcomes poorer. Middlesbrough has some of the highest areas of deprivation. Aim(s): To evaluate diagnostic value of CT screening pilot in detecting lung cancer and follow-up outcomes for patients with incidental finding of pulmonary nodules. Method(s): Between March 2019 - December 2022 17 GP practices in Middlesbrough were invited to offer non-contrast CT thorax to asymptomatic COPD patients eligible for review, aged 50-75 with 20 pack year history and QCancer risk >5%. Pulmonary nodules followed up as per BTS guidelines. This pilot was conducted in partnership and with support from the Northern Cancer Alliance. Result(s): 407 patients referred for CT, 312 met the criteria and enrolled. 5 (1.6% conversion rate) lung cancers, also 1 renal cancer diagnosed. 51 (17%) had features of pulmonary nodules or groundglass opacities and selected for follow up. 2 died from COVID infection before follow-up CT. 32 (62.8%) discharged after followup CT revealed stable appearances or resolution, follow-up CT still outstanding for 2. 4 (7.8%) selected for further follow-up of sub-solid, new or increasing nodules. 2 (3.9%) received radiological diagnosis of lung cancer and referred for radiotherapy, 1 underwent surgical resection revealing lung tumourlets and 1 referred for surgical resection of enlarging nodule. Conclusion(s): Pulmonary nodules consisted significant part of the CT screening pilot findings in COPD patients with significant further conversion rate to lung cancer diagnosis after follow-up. Therefore, CT screening of high-risk population in deprived areas has a role in detecting lung cancer and identifying pulmonary nodules, with a proportion of those later diagnosed as early lung cancer.

ABSTRACT
Introduction: Active cancer increases the odds of death among patients with COVID-19.1 Cancer patients may be at increased risk of complications and mortality from COVID-19 owing to the systemic effects of malignancy, immune suppression after chemotherapy, treatment-related complications and presence of co-morbidities.2 They may develop serious complications necessitating ICU admission. In a meta-analysis, the pooled mortality in cancer patients with COVID-19 admitted to an ICU was 60.2%.3 Our hospital is a tertiary referral cancer centre, and the ICU admitted cancer patients with Covid-19 throughout the pandemic. Objective(s): To determine the 30-day in-hospital mortality of adult cancer patients with Covid-19 admitted to the ICU. We also aimed to determine the factors associated with mortality in cancer patients with Covid-19. Method(s): After approval from the Institutional Ethics Committee, data of all cancer patients (age = 16 years) with Covid-19 admitted to the ICU between March 2020 and March 2021 were retrieved from the hospital records. In case of multiple ICU admissions, data from the first admission was recorded. Data recorded included demographic details, type of cancer (solid, haematological), surgical status, APACHE-II and SOFA scores, C-reactive protein, and interventions in ICU. The primary outcome was 30-day in-hospital mortality. Data were analysed using Man-Whitney test and chi-square test. A multivariable regression analysis was carried out to determine factors associated with mortality. Result(s): Data of 127 cancer patients with Covid-19 was analysed. The median [interquartile range, IQR] age was 55 (43-62) years, and there were 50 females (39.3%). Comorbidities were present in 46 (36%) patients, the commonest being diabetes (29 patients) and hypertension (31 patients). The median [IQR] APACHE-II and SOFA scores were 15[8-20] and 4[2-7], respectively. Overall, 62/127 patients died, and 30-day hospital mortality was 49%. There were 30 patients with haematological malignancy and 97 with solid tumours with 30-day in-hospital mortality rates of 46.7% and 49.5%, respectively;p = 0.84). Amongst patients with solid tumours, there was no difference in mortality in surgical patients compared to non-surgical patients (43.3% vs. 52.2%;p = 0.42). Table 1 summarises the parameters and interventions in survivors and non-survivors. On multivariable analysis, only the change in SOFA score from Day 1 to Day 3 was independently associated with outcome (Odds ratio 1.36 (95% confidence interval 1.01-1.84, p-0.04). Conclusion(s): In patients with cancer and Covid-19 and age =16 years admitted to our ICU, the crude 30-day hospital mortality was 47%. There was no association of mortality with cancer type or surgical status. The only independent predictor of mortality was progression of organ failure. Cancer patients with Covid-19 have a reasonable outcome and should be given a trial of intensive care.
ABSTRACT
Introduction: Pediatric brain tumors are the most common tumor in children after hematological malignancies. There is very few data about the epidemiology of pediatric brain tumors in India. Methods - This was a prospective and retrospective study in pediatric patients who had undergone surgery in our institute (JIPMER,Pondicherry). 80 cases were recruited and followed up for minimum follow up period of 1 year. The demographic profile was analysed and IHC markers were done for embroyonal tumors and glioma. Result(s): Pediatric brain tumors was equally distributed among male and females. (1:1) .Mean age of presentation was 10 years . 27.5 % of our cases were embryonal tumors,low grade glioma (16.25 % ) ,high grade glioma ( 12.5 % ) ,ependymoma and craniopharyngioma comprised 15 % of our cases each. Medulloblastoma comprised 23.75 % of cases Out of which 31.5 % had craniospinal metastasis at time of diagnosis. The most common location of SHH pathway medulloblastoma was cerebellar hemisphere and non WNT/non SHH was fourth ventricle. 45.45 % of patients with high grade glioma had recurrence .50 % of ependymoma cases were infratentorial. we had 2 cases of ganglioglioma ,one in the midbrain and other in temporal lobe .Gross total resection was achieved in 30 % ,Subtotal resection in 46.25 % and partial resection in 20 % of our cases. Outcome of patients at the end of 1 year for low and high grade glioma, ependymoma and craniopharyngioma were similar to western literature. Two patients acquired COVID 19 and died while undergoing treatment. Molecular markers like INI1, LIN28 A was highly sensitive and specific for diagnosing atypical teratoid rhabdoid tumor (ATRT) and embryonal tumor with multilayered rosettes (ETMR )respectively. Conclusion(s): Our study emphasizes the need of standardized and systemic cancer registries in India. (Figure Presented).
ABSTRACT
Introduction: To restrict the spread of COVID-19 infection, billions of people around the world have been quarantined or in social isolation. As a result of these health public measures, only essential services were maintained. Outpatient consultations and non-urgent surgeries were suspended to reduce hospitalizations and the risk of contagion. This context resulted in a delay in the diagnosis of several diseases, including head and neck cancer (HNC). Objective(s): To assess the impact of the COVID-19 pandemic on the treatment of HNC, comparing the number of surgery and radiotherapy, and chemotherapy procedures carried out during the pre-pandemic and pandemic periods in Brazil. Material(s) and Method(s): We compared the mean number of HNC surgeries and the number of radiotherapy and chemotherapy procedures carried out during the pre-pandemic (from March to July 2015-2019) and pandemic period (from March to July 2020) in the five geographic regions of Brazil. Result(s): Between 2015 and 2019, the mean number of surgeries for HNC was 5410. In 2020, during the same period, there were 3522 surgeries, representing a 35% decrease during the pandemic period. The greatest decrease was observed in the Northern region (60.7%). The number of radiotherapy and chemotherapy procedures increased by 50,8% in the pandemic period, with a higher prevalence in the Northeast (75.1%). Conclusion(s): During the peak of the COVID-19 pandemic, the data demonstrate a likely change in the HNC treatment protocol in Brazil.
ABSTRACT
Objectives: To present a series of immunosuppressed patients (oncohematological disease, congenital immunosuppression, hematopoietic stem cell (HSCT), and solid organ transplant) assisted on ECMO. Method(s): Descriptive, retrospective study (2011-2020) of a cohort of 9 immunosuppressed patients, supported on ECMO. Medical records were reviewed and demographic, clinical, and analytical variables were collected. Result(s): In our series of 9 patients, 5 were male, the median age was 8 years [RIC 3-11 years]. Considering the underlying disease, 6 were oncologic, 1 liver transplant and 2 with congenital immunodeficiency after HSCT. 4 were under active chemotherapy (median 6 days after the last cycle [RIC 5-188]). 6 were admitted due to acute respiratory failure, 3 due to hemodynamic instability (3/9), (one septic shock). The median PEEP was 12 [RIC 9-15] and FiO2 100% (81-100%). 78% (6) required vasoactive drugs (median inotropic score 35 [RIC 0-75]. 40%. 5 had severe neutropenia and/or plateletopenia in the 24 hours prior to ECMO, and alterations in acid-base balance (median pH 7. 1 [RIC 6.9-7.15]. 5 were on multiorgan failure. TPrimary ECMO transport was performed in 4 patients (44%). Cannulation was peripheral in 80% (57% cervical, 43% femoral) and central in 20%;70% VA-ECMO. Median time of assistance was 15 days [RIC 3.5-31.5] in cardiac ECMO (4), and 29 days [RIC 13.5-42] and in pulmonary ECMO (n=5). The median total time of admission was 45 days [RIC 27-59]. 9 had an infection, 2 COVID after HSCT, and 8 bleeding complications, but only one required surgical revision. Renal replacement therapy was used in 5 (median 9 days [RIC 5-34.5]). Other therapies used were polymyxin hemadsorption(2), intratracheal surfactant(2), plasma exchange(1), infusion of mesenchymal cells(1) and specific memory T lymphocytes(2). 4 patients died, 5 survived decannulation, 2 died later, with an overall survival rate to hospital discharge of 33% (3/9). Conclusion(s): Despite having a worse prognosis, ECMO can increase survival in immunosuppressed patients, in situations that are challenging and require a multidisciplinary approach.
ABSTRACT
Introduction: Melanoma of the rectum is an extremely rare disease. The median survival rate is 2-5 years. Current treatment for this aggressive cancer is resection if possible and consider adjuvant or neoadjuvant radiotherapy;immunotherapy in nonresectable cases. Given the rapid spread of disease due to its submucosal growth and metastasis pattern, there is low success rates with treatments. Case Description/Methods: An 84-year-old male presented to the emergency department with an acute COVID-19 infection. The patient was also found to have gram-negative septicemia on blood cultures, so a CT abdomen/pelvis was performed (Figure 1a). The CT showed rectal wall thickening. A flexible sigmoidoscopy was planned for a future outpatient visit after recovering from his acute infection. The patient, however, developed an acute onset of dyspnea and had a high probability V/Q scan while in the hospital. He was started on anticoagulation, and shortly after starting therapy the patient developed bright red rectal bleeding. Due to the new onset of rectal bleeding it was decided to expedite the sigmoidoscopy. The sigmoidoscopy was performed in the hospital showing an ulcerated partially black pigmented non- obstructing medium-sized mass that was partially circumferential involving one-third of the lumen (Figure 1b). A biopsy of the lesion was taken using cold-forceps. The pathology stained positive for S100 consistent with melanoma. The diagnosis of anorectal melanoma was made, and colorectal surgery was consulted. The patient was deemed not to be a surgical candidate secondary to age and active COVID-19 infection. Oncology was consulted, and it was decided to start the patient on radiation and immunotherapy with a PD-1 inhibitor. Discussion(s): The symptoms of anorectal melanoma can be subtle and in this case report completely asymptomatic. Symptoms to be aware of are rectal bleeding and tenesmus. Diagnosing melanoma on sigmoidoscopy can be challenging as most tumors are not pigmented. Biopsies should be taken and sent for immunohistochemical staining for S100, if positive the patient should have a PET scan. Treatment choices for the tumor are based on staging. In a resectable tumor sphincter-saving local excision with radiotherapy to the site of the tumor and the pericolic and inguinal lymphatics is recommended. For unresectable tumors or tumors with distant metastasis, immunotherapy with PD-1 inhibitors (nivolumab and ipilimumab) is an emerging treatment choice.
ABSTRACT
Introduction: Mucinous adenocarcinomas of the appendix are defined as epithelial neoplasms often causing cystic dilation of the appendix due to accumulation of gelatinous material. Pseudomyxoma peritonei is an extremely rare complication of appendiceal mucinous adenocarcinomas with an estimated incidence rate of one to 2 people per million per year. Here-in we present a unique case of enterocutaneous fistula formation secondary to percutaneous biopsy of an enlarging omental mass in the setting of pseudomyxoma peritonei. Case Description/Methods: A 50-year-old male with a past medical history of metastatic appendiceal mucinous adenocarcinoma presented to the ED with abdominal pain, nausea, and vomiting. The patient had previously undergone 2 debulking surgeries over the past 2 years prior to admission and has since been on FOLFOX therapy. Due to the COVID pandemic, the patient did not follow-up in the 2 years period from previous admission. A CT scan was now notable for a new enlarging omental mass despite the recent debulking surgery. Given the enlarging mass, a decision was made to pursue a percutaneous biopsy of the mass due to concern for potential new malignancy. Two weeks after the biopsy, the patient presented to our facility due to worsening erythema and drainage from the biopsy site. The patient met SIRS criteria, thus broad-spectrum antibiotics were initiated. A CT of the abdomen and pelvis with oral and IV contrast was obtained, which demonstrated a 9 cm abscess or continuation of intra-abdominal multilocular cystic lesion/ pseudomyxoma peritonei. The surgical team was consulted. Patient had 100 cc of purulent and mucinous drainage expressed from biopsy site. The patient was then placed for transfer to a hospital capable of advanced surgical management for evaluation and potential resection of fistula formation. The patient had a successful reductive surgery and intraoperative chemotherapy (Figure). Discussion(s): Given the rarity of pseudomyxoma peritonei, appropriate management is not always straightforward. A literature review yielded no previous reports of enterocutaneous fistula as a complication of percutaneous drainage in the setting of pseudomyxoma peritonei. We recommend that percutaneous drainage not be sought in individuals with this diagnosis due to potential for fistula formation.
ABSTRACT
Objectives: Post Covid severe vomiting together with proximal muscle weakness is a misleading combination, this describes a rare but definite clinical association between myasthenia gravis and autonomic failure and strengthen the concept that subacute autonomic neuropathy is an autoimmune disorder. Content: A 39 ys old adult female presented with postCovid severe vomiting for one year with 40 kgs loss Upper gastrointestinal endoscopy revealed gastric dilatation associated with eosophageal and gastric stasis and hypertrophic pyloric stenosis. the gastroenterologist sought neurological consultation for the coexisting unexplained limb weakness before operation EMG & NCV was all normal except instability of the MUAPs Slow rate Repetitive supramaximal stimulation (RNS) revealed significant decremental response with no significant high rate stimulation incrementation Chest CT revealed an anterior mediastinal mass Surprisingly, She had an old CT during the covid infection that showed the same mass. Thoracoscopic resection revealed type B1 thymoma Following tumor resection, the patient improved gradually, Few months later endoscopy revealed a normal stomach with strong peristaltic waves and the patient was symptom free Infections are recognized to trigger exacerbations and crisis in MG Dysautonomia is not a commonly recognized feature of myasthenia gravis, but there have been rare reports of myasthenia gravis coexisting with autonomic failure, usually in association with thymoma. The autonomic dysfunction can present as isolated gastroparesis these observations support a rare but definite clinical association between myasthenia gravis and autonomic failure Neurophysiology could reveal undiagnosed MG with thymoma causing autonomic dysfunction in the form of gastroparesis and agonizing vomiting.

ABSTRACT
Introduction: Congenital choledochal cyst (CCC) is a rare cystic dilatation of intrahepatic or extrahepatic biliary ducts. We present a case of a type IVb choledochal cyst presenting as recurrent acute pancreatitis in a young healthy female with initial negative screenings. Case Description/Methods: An 18-year-old-female with a history of COVID-19 presented to the emergency department with one month of persistent abdominal pain, nausea, and vomiting. She was hospitalized once prior for similar symptoms and was diagnosed with acute pancreatitis. This admission, blood work showed elevated lipase, elevated liver enzymes, mild bilirubinemia with a normal lipid panel and urine was significant for infection. She received fluids, antiemetics and was started on prophylactic antibiotics for ascending cholangitis. A right upper quadrant ultrasound ruled out cholelithiasis or acute cholecystitis, but showed dilation of the common bile duct. MRCP confirmed dilation with bulbous termination in the periampullary region diagnosed as type IVb choledochal cyst. Discussion(s): CCCs are rare in Western countries with an incidence between 1 in 100,000 to 150,000. 80% of these cysts are diagnosed in patients under the age of 10. They are difficult to diagnose due to variable clinical presentations. A study of 214 CCC patients demonstrated the most common symptom was abdominal pain, followed by jaundice and fever. When cysts are found in adults, symptoms resemble atypical acute biliary tract disease. Surgical cyst removal may be needed for patients with significant risk factors such as older age and age of symptom onset, due to increased risk of malignant transformation. Longer periods of observation have been documented to be associated with an increased chance of developing late complications, such as anastomotic stricture, biliary calculi and recurrent cholangitis. Type IVb CCCs, as seen in this case, consist of multiple extrahepatic cysts and hepaticojejunostomy is the treatment. This patient's young age and recurrent acute pancreatitis combined with her lab and imaging findings strongly suggest the diagnosis of CCC. The anatomical location of the CCC impeded flow of pancreatic enzymes through the ampulla of vater, leading to recurrent pancreatitis in an otherwise healthy young female. CCC, although very rare, should be considered in the differential of acute pancreatitis when other causes such as gallstones and heavy alcohol consumption cannot be identified, as prompt diagnosis and surgical removal is imperative.
ABSTRACT
Introduction: Hepatocellular carcinoma (HCC) comprises the majority of primary liver cancer and has a poor prognosis. Clivus metastasis is rare with only a few reported cases in the medical literature. We report a case of a patient who presented with clival mass found to have metastatic HCC. Case Description/Methods: A 63-year-old woman presented for neurosurgical evaluation after she was found to have a skull base mass on computerized tomography (CT) of the head at an outside hospital. She endorsed dysphagia for three months, however denied headaches or visual disturbances. A magnetic resonance imaging (MRI) revealed a 5.4 cm by 2.9 cm by 3.6 cm mass in the clivus, which was deemed as the cause of dysphagia (Figure 1a). The patient subsequently underwent an endoscopic transsphenoidal resection of the clival mass. Histopathology from the tissue revealed a hepatoid carcinoma, concerning for metastatic HCC (Figure 1b and 2c). Immunohistochemical strains were positive for hepatocytic marker arginase-1 (Figure 1d). Laboratory studies revealed alpha fetoprotein (AFP) of 56,344 ng/mL, CA-125 of 376 ng/mL, normal B-HCG and carcinoembryonic antigen (CEA). Thereafter, a triple phase CT of the liver revealed two LI-RADS 5 lesions suggestive of HCC as the primary malignancy. Patient's case was discussed at multidisciplinary tumor board with recommendations for systemic immunotherapy with atezolimumab plus bevacizumab and radiation therapy to the clivus. Discussion(s): The incidence of HCC has almost tripled since the 1980s making it the fastest rising cause of cancer related deaths. Metastasis to the brain comprises 0.26% to 2.2% of cases and the skull base is the most rarely affected anatomical site. Although CNS presentation is rare, we may see more neurological manifestations of metastatic HCC with the persistence of chronic hepatitis infections, the rise of metabolic diseases such as NASH, and an increase in alcohol-related liver disease during the COVID-19 pandemic. Although exceedingly rare, metastasis to the clivus should be considered in the differential diagnosis of skull base masses. Despite detection and treatment, prognosis remains poor and emphasis should be placed on consistent HCC surveillance. This case emphasizes that skull masses must be evaluated diligently as they can be the first sign of underlying liver malignancy. Given the morbidity and mortality associated with HCC, recognition of atypical manifestations of HCC can lead to a prompt diagnosis and initiation of life-saving treatment. (Figure Presented).
ABSTRACT
Introduction: Autoimmune enteropathy (AIE) is a very rare immune disorder that mainly attacks the gastrointestinal tract by T-cell. The full pathology mechanism is not clear. Typically, characterized by intractable diarrhea and nutritional malabsorption with extra-intestinal manifestations. The proposed diagnostic criteria include small bowel villous atrophy not responding to diet restriction, circulating gut epithelial cell autoantibodies (GECA), and lack of immunodeficiency. We describe a case of AIE with extensive GI involvement, presenting in a 60-year-old patient diagnosed with Type AB thymoma. Case Description/Methods: Our gentleman with a history of Covid-19 complicated with pulmonary embolism and an incidental finding of malignant thymoma. A CT-guided biopsy was consistent with undifferentiated malignant thymoma supported by immunohistochemistry staining. Subsequently, complicated severe diarrhea erupted with significant weight loss. Conservative management, antibiotics, and diet restriction were ineffective. Diagnostic work-up was unremarkable except for anti-enterocytes antibodies (AEA) and anti-goblet cells antibodies (AGA). Bowel biopsy revealed villous blunting, loss of Paneth cells, and minimal intraepithelial lymphocytosis with no evidence of crypt abscesses. Corticosteroid and Octreotide have helped the patient's diarrhea. Thoracoscopy thymectomy performed with radiation therapy due to local and lymphovascular invasion. Discussion(s): AIE characterized by severe villous blunting with the absence of goblet cells and Paneth cells, intraepithelial lymphocytosis, and increased crypt apoptosis. In comparison, graft vs host disease lack crypt abscesses, celiac disease shows increase in the intraepithelial lymphocytosis with intact goblet and Paneth cells, whereas inflammatory bowel disease has intact goblet and Paneth cells, and CVID characterized by absence of plasma cell in the lamina propria. The presences of the GECA are nonspecific but it may help in confirming the diagnosis or may predict the prognosis and recurrence. Only AGA has been reported in IBD. Neither has been observed in celiac disease. The low incidence of AIE and the limited existing literature available on the optimal guidance in management. Oral nutritional supplementation as well as total parenteral nutrition is helpful. The target is to control diarrhea and optimize the nutritional status before surgery. The main treatment is thymectomy.
ABSTRACT
Ablation includes ethanol injection, radiofrequency ablation (RFA), microwave ablation (MWA), etc. Ablation can be potentially curative, minimally invasive and easily repeatable for recurrence. RFA has been the most widely used ablation technique for liver tumors. The new-generation MWA system incorporating antenna cooling and high-power generation has attracted attention. It can create a more predictable ablation zone and a larger ablation volume in a shorter procedure time. Many high-volume centers have introduced new-generation MWA in Japan. However, many studies failed to show that new-generation MWA is superior to RFA in terms of local control and overall survival. In MWA, clinical data have been insufficient compared with those of RFA. There has been keen competition between surgical resection and ablation for almost 40 years since the era of ethanol injection. In 2021, SURF trial revealed that overall survival and recurrence-free survival were not significantly different between surgical resection and RFA. SURF trial was a multicenter randomized controlled trial in which 49 major centers in Japan enrolled patients with good hepatic function (Child-Pugh scores <= 7) and primary HCC of largest diameter <= 3 cm, and <= 3 nodules during the 6-year period of 2009-2015. The registered patients were followed for at least 5 years. As the result of SURF trial and other comparative studies, the revised Japanese clinical practice guidelines in 2021 treats hepatic resection and ablation equally for patients with <= 3 lesions, <= 3 cm in diameter. Recently, the combination of systemic and locoregional therapies has been attracting much attention. Systemic therapy using molecular targeted agents or immune checkpoint inhibitors is used for advanced HCC which cannot be treated by surgery or ablation. On the other hand, some locoregional therapies, such as hepatectomy and ablation, are potentially curative, but they cannot be indicated for advanced HCC. Combination of both therapies is an approach to improve the prognosis of advanced HCC, which is not indicated for curative treatment. Systemic therapy is used to shrink the tumor, and then locoregional therapies are performed to eradicate it. The combination may build a new strategy for advanced HCC. Ablation is highly operator-dependent. The skills and outcomes are very different from operator to operator. Before the pandemic of COVID-19, we held domestic and international training programs for intermediate and advanced doctors and hands-on seminars for young doctors. These were activities to exchange knowledge and experience and standardize the procedure. During the pandemic, we cannot get together. Since August 2020, we have conducted Japan Ablation Webinar 8 times with a total of 1,566 participants. We have also conducted International Ablation Webinar 4 times with a total of 1,272 participated doctors. Education is important to acquire skills and knowledge for successful ablation. We have established Japan Academy of Tumor Ablation (JATA) this year. There are two triggers. One is that SURF trial revealed that there is no difference between hepatectomy and ablation. The other is that ablation for lung, bone and soft tissue and kidney cancers has become reimbursed with health insurance since this September.
ABSTRACT
Background/Aims A 72-year-old lady presented in primary care with complaints of generalised body aches, bilateral leg weakness and constitutional symptoms following a first dose of COVID-19 vaccine. Blood tests showed slightly raised inflammatory markers. She was initially diagnosed with polymyalgia rheumatica and was started on 40mg prednisolone with minimal improvement. Methods The examination in the rheumatology clinic was unremarkable. Investigations revealed raised white cell count, consistent with high dose steroid treatment, and elevated monocytes. There was mild improvement in inflammatory markers. The working diagnosis was of self-limiting viral illness. Further testing discovered strongly positive MPO ANCA (115 IU/ml), and the patient received three pulses of 500mg methylprednisolone for suspected vasculitis arranged by the medical team. There was no evidence of renal involvement. The diagnosis made at this point was autoimmune inflammatory disorder with unclear aetiology. At the subsequent clinic visit she reported mild shortness of breath, but no other symptoms suggestive of either vasculitis or connective tissue disease. Repeat ANCA showed significant reduction in MPO titre following pulse steroid treatment. CT of chest, abdomen and pelvis demonstrated a localised lobular/ nodular deformity of the liver. Viral hepatitis screen was negative. CA19-9 was raised at 100 U/ml. Liver biopsy was reported as poorly differentiated carcinoma without specific localising immunohistochemical features. Results The patient underwent hemi-hepatectomy for histologically confirmed pT2pNXM0R0 liver cholangiocarcinoma in a tertiary centre followed by adjuvant chemotherapy with capecitabine. With treatment, her MPO ANCA and CA19-9 levels declined. An interval CT scan of chest, abdomen and pelvis performed ten months after the surgery, showed no recurrence of malignancy. Given the fact that the patient's MPO ANCA fell following the treatment of cholangiocarcinoma, it is likely that positive MPO ANCA is associated with underlying malignancy rather than an active vasculitis. Conclusion This unusual case describes an evolution of the diagnostic process guided by non-specific symptoms and ANCA positivity, arriving at an unexpected diagnosis of malignancy. Although ANCA is a sensitive and specific marker of vasculitides, it can be positive in other conditions particularly hepatitis B, inflammatory bowel disease and autoimmune liver disorders. Malignancy can also be associated with ANCA in the absence of vasculitis. In one study, of 118 ANCA positive patients without ANCA-associated vasculitis, four were found to have malignancy. In a study of 1024 patients who had ANCA tested, 61 patients were found to have malignancy, predominantly haematological and lung cancers. However, after adjustment for sex, age and time of blood draw, no association was found between ANCA status and incidence of cancer. Interestingly, paraneoplastic vasculitis such as polyarteritis nodosa (PAN) has been described in the context of underlying cholangiocarcinoma, and is associated with ANCA rise. Moreover, patients with raised ANCA and PAN also have raised CA 19- 9.
