RESUMO

Low-grade serous ovarian cancer (LGSOC) is a very rare histological subtype of serous ovarian cancer, representing ~2% of all epithelial ovarian cancer cases. LGSOC has a better prognosis but a lower response rate to chemotherapy in comparison to high-grade serous ovarian carcinoma (HGSOC). The present study is a retrospective review of the medical records of all patients with histologically proven LGSOC diagnosed and treated in a single institute between January 2003 and December 2019. A total of 23 patients diagnosed with LGSOC and treated at King Faisal Specialist Hospital and Research Center (Riyadh, Saudi Arabia) were identified. The median age at diagnosis was 45.5 years (range, 26-66 years) and the median body mass index was 26.1 (range, 18-43). A total of 21 patients (91.3%) had de novo LGSOC, whereas only 2 patients (8.7%) had LGSOC that had transformed from serous borderline ovarian tumors and recurred. A total of 8 patients (34.8%) were diagnosed with International Federation of Gynecology and Obstetrics stage IV, whereas 3 (13.0%), 3 (13.0%) and 9 (39.1%) were diagnosed with stages I, II and III, respectively. In addition, 10 (43.5%), 5 (21.7%), and 3 (13.0%) patients had complete response, stable disease and partial response statuses after first-line therapy, respectively. At a median follow-up time of 34 months [95% confidence interval (CI), 25.32-42.69], the median progression-free survival (PFS) time was 75.2 months (95% CI, 17.35-133.05) and the median overall survival (OS) time was not reached. In conclusion, LGSOC exhibited better PFS and OS times than HGSOC as compared with data from the literature, and there is the option for systemic treatment (chemotherapy or hormonal therapy). Optimal cytoreduction showed numerically higher, but non-significant, PFS and OS times compared with suboptimal debulking; however, the optimal systemic chemotherapy or hormonal treatment remains controversial.

RESUMO

Introduction and importance: NUT carcinoma of the thorax is an extremely rare neoplasm characterized by a translocation between the NUT M1 gene and members of the bromodomain genetic family. Due to the rarity of the neoplasm, standardized treatment guidelines have not yet been established. Several chemotherapeutic agents have been used with limited success, due to the rapid development of resistance to treatment. Pembrolizumab, an anti-programmed-death-1 antibody, has become increasingly used in non-small-cell lung carcinomas. Consequently, pembrolizumab may be beneficial in the treatment of NUT carcinoma. Case presentation: In this article, we discuss the case of a 24-year-old man who was referred to our centre due to an incidental mass finding on an unrelated computed tomography scan. Morphological and immunohistochemical characteristics are highly suspicious of NUT carcinoma with bone metastasis. The patient was placed on carboplatin, paclitaxel, and pembrolizumab as first-line therapy. The patient later progressed and began receiving second-line treatment according to Ewing's protocol. 20 months later, the mass continued to grow, and the patient was started on docetaxel and gemcitabine, which was unsuccessful. After discussing with the patient, he decided to stop chemotherapy and begin palliative care. Clinical discussion: NUT carcinoma is an aggressive tumour with poor prognosis. Treatment options are limited and pembrolizumab does not seem to influence the clinical outcome of the neoplasm. Conclusion: Overall, pembrolizumab does not seem to improve the outcomes of NUT carcinoma patients. To the authors' knowledge, this is the second article reporting the effects of pembrolizumab on the progression of NUT carcinoma.

RESUMO

SARS-CoV-2 infection induces myocardiopathy in 19% of severe cases, with a mortality rate of up to 51%. The mainstay of treatment is supportive care, steroids, and tocilizumab (anti-IL-6). This is a case of a 43-year-old woman diagnosed with hormone-positive breast cancer with lung metastasis and pulmonary lymphangitis carcinomatosis (PLC). Her baseline cardiac function was within normal limits. She presented to the emergency department with respiratory distress. Chest CT showed multiple bilateral ground-glass opacities consistent with COVID-19 pneumonia and confirmed by COVID-19-PCR nasal swab. Her condition deteriorated, and she was urgently admitted to the intensive care unit with evidence of a cytokine storm. She was started on tocilizumab, dexamethasone, and meropenem. Echocardiogram (echo) showed a severely reduced ejection fraction with severe global hypokinesis. A second dose of tocilizumab was given, and the dexamethasone dose was increased. Fortunately, the patient had significant clinical and biochemical improvement and regained her normal cardiac function. In conclusion, dexamethasone and tocilizumab could be promising aids in treating cardiomyopathy secondary to SARS-CoV-2 infection.

RESUMO

Sclerosing epithelioid fibrosarcoma is an ultra-rare and aggressive high-grade fibrosarcoma that was originally described in 1995. More than 100 cases are documented worldwide, with the most extensive case series reporting a high rate of recurrence and metastasis. ALK mutations are commonly seen in soft-tissue sarcomas; however, this is the first known case of an ALK V757M mutation. Here, we present a case using crizotinib in treating an ALK-positive sclerosing epithelioid fibrosarcoma refractory to all traditional treatment options.

RESUMO

Patients with primary refractory Hodgkin lymphoma (ref-HL) can still be salvaged with high-dose chemotherapy (HDC) and autologous stem cell transplantation (auto-SCT). Outcomes of patients with ref-HL is poorer than those with relapsed HL, but most studies have included patients with both relapsed and refractory diseases, and separate analyses or studies on patients with ref-HL are limited. This study aimed to evaluate the outcomes of HDC auto-SCT and impact of various prognostic factors in patients with ref-HL at the time of primary treatment failure and subsequent survival at the time of failure post-HDC auto-SCT. This retrospective single-institution cohort analysis using an HDC and auto-SCT database was approved by the Institutional Research Advisory Counsel and Ethics Committee for identifying patients. We used the Fine and Gray competing risk analysis method, a regression model for outcome analysis, and the Kaplan-Meier (KM) method for survival analysis. The study cohort comprised 200 consecutive ref-HL patients who underwent HDC auto-SCT between 1996 and 2019. The median patient age was 22.75 years, and median follow-up was 106 months. Post-auto-SCT disease status was complete remission (CR) in 122 patients (61%), partial remission in 22 (11%), and progressive disease in 47 (23.5%). KM median progression-free survival (PFS) after auto-SCT was 43.9 months (5 years, 49.3%; 10 years, 45.5%). Median overall survival (OS) was 168.6 months (5 years, 61.2%: 10 years, 56.2%). Eighty-five patients (44.5%) died, 69 (34.5%) due to disease. Multivariate analysis identified similar adverse factors for both PFS and OS. For PFS, these adverse factors included stage III-IV at relapse (hazard ratio [HR], 1.65; P = .045), mediastinal involvement (HR, 2.01; P = .009), and absence of CR after salvage chemotherapy (HR, 2.2; P = .001). PFS with 0 or 1 adverse factors (not reached), 2 adverse factors (40.8 months), and 3 adverse factors (5.4 months) was significant (P < .001). For OS, significant adverse factors included stage III-IV at relapse (HR, 1.68; P = .045), mediastinal involvement (HR, 2.52; P = .007), and no CR after salvage chemotherapy (HR, 2.15; P = .004) were significant. OS with 0 or 1 adverse factors (not reached), 2 adverse factors (148.5 months), and 3 adverse factors (34.4 months) was significant (P < .001). The median OS after auto-SCT failure was 23.6 months; patients received post auto-SCT brentuximab/second SCT (not reached), other treatments (22.5 months), and supportive care (8.4 months) (P < .001). OS with 5 risk factors present at HDC auto-SCT failure- stage III-IV, failure at <12 months, tumor >5 cm, B symptoms, and low serum albumin-was 152 months for 0 or 1 risk factors, 30.9 months with 2 risk factors, and 9.45 months with 3 to 5 risk factors (P < .001). Ref-HL patients have encouraging survival after HDC auto-SCT and can even be salvaged after auto-SCT failure. Based on prognostic factors, survival prediction is possible. Patients who fail to respond to HDC auto-SCT may benefit from newer treatments strategies and may qualify for enrollment in clinical trials.

RESUMO

Human epidermal growth factor receptor-positive breast cancer is an aggressive cancer which represents approximately a quarter of all breast cancers worldwide. Recent advances have led to the development of targeted therapies, such as trastuzumab (H), which have significantly improved prognosis. Such therapies are currently used alongside other chemotherapeutic agents, such as paclitaxel (P) and gemcitabine (G). The most common side effects of PGH combination therapy include thrombocytopenia and anemias. However, there have been no previous reports of myositis resulting from this combination. We report the case of a 54-year-old metastatic breast cancer patient on PGH therapy who developed muscle weakness. The patient was initially treated with trastuzumab, pertuzumab, and paclitaxel. However, pertuzumab was changed to gemcitabine due to severe diarrhea. After the fourth cycle of PGH, the patient presented with muscle weakness and creatine kinase levels of up to 6755 U/L. Magnetic resonance imaging of the femur and pelvis revealed diffuse bilateral myositis, suggesting a diagnosis of gemcitabine-induced myositis. The patient was placed on intravenous fluids and corticosteroids, which resolved her condition. To our knowledge, this is the first report of gemcitabine-induced myositis in a breast cancer patient. Further studies are needed to determine the underlying mechanisms of gemcitabine-induced myositis and develop preventative measures.

RESUMO

Small bowel adenocarcinoma (SBA) is an extremely rare cancer type. In the present study, the patient characteristics and clinical outcomes of patients diagnosed and treated for SBA at a single tertiary hospital were reported. All patients diagnosed and managed between 2007 and 2020 were reviewed. Regression analysis was used to assess variables associated with the metastatic stage at diagnosis. The Kaplan-Meier method was used to estimate survival and the log-rank test was used to determine factors associated with survival outcomes. Out of 137 cases of small bowel primary tumor, 43 consecutive patients with SBA were diagnosed with a median age of 53 years and the majority (76.7%) were males. The common initial presenting symptoms were abdominal pain (58.8%) and bowel obstruction (30.2%). The most common primary site was the duodenum (60.5%) and the majority (65.1%) were diagnosed with stage III/IV disease. Patients with a high neutrophil-lymphocyte ratio (NLR) (≥0.85) were more likely to be in the metastatic stage at diagnosis (P=0.01). The 3-year overall survival (OS) rates based on stage were 100% (I), 85% (II), 53% (III) and 33.9% (IV) (P=0.001). In addition to the stage, the Eastern Cooperative Oncology Group Performance Status (P<0.001), NLR (P<0.001), hypoalbuminemia (P=0.02) and chemotherapy in a metastatic setting (P=0.02) were prognostic factors for OS. In conclusion, NLR is a potential prognostic biomarker for a metastatic stage at diagnosis. Advanced stage, lower performance status score, low albumin level and high NLR are associated with short OS.

RESUMO

BACKGROUND: The peritoneum frequently is the only recurrence site after radical resection of gastric cancer. Data suggest that hyperthermic intraperitoneal chemotherapy (HIPEC) and intraoperative radiotherapy (IORT) reduce peritoneal recurrence and possibly improve survival for patients with resected gastric and serosal involvement. This study aimed to evaluate the efficacy of combining prophylactic HIPEC and IORT after radical resection of localized gastric cancer. METHODS: In this retrospective study, the medical records of adult patients with histologically proven gastric/gastroesophageal adenocarcinoma who underwent radical resection with curative intent were evaluated for recurrence and survival according to whether they received prophylactic HIPEC and IORT. RESULTS: The eligibility criteria were met by 58 patients, 33 of whom underwent prophylactic HIPEC and IORT after radical surgery. Overall, 91% the HIPEC/IORT group and 72% of the surgery-only group had ≤pT3 disease. The median follow-up period was 26.6 months for the HIPEC/IORT group and 50.6 months for the surgery group. Locoregional recurrence occurred for six patients (18.1%) in the HIPEC/IORT group and five patients (20%) in the surgery-only group, with peritoneal metastasis (PM) occurring in respectively three (9%) and six (24%) patients. The median recurrence-free survival (RFS) duration was 23.2 months (95% confidence interval [CI] 6.5-39.9 months) for the HIPEC/IORT group versus 24.8 months (95% CI 0.0-51.1 months) for the surgery-only group (p = 0.88), and the corresponding 5-year overall survival (OS) estimates were 69% and 58%. CONCLUSION: Prophylactic HIPEC and IORT after radical surgery for localized gastric or gastroesophageal cancer did not improve RFS or OS for an unselected group of patients at risk for peritoneal recurrence.

RESUMO

OBJECTIVES:  Ovarian granulosa cell tumour is rare. This study aims to report the clinical characteristics and long-term outcomes of adult-type ovarian granulosa cell tumour (AOGCT) at King Faisal Specialist Hospital and Research Centre (KFSH&RC) and to determine the prognostic factors affecting relapse and survival. METHODS: We retrospectively reviewed patients with AOGCT, from 1988 to 2014, who were treated at our institution. Baseline characteristics, pathological findings, and outcomes were analysed and reported. RESULTS: Sixty-one patients with AOGCT were identified with a median age of 49 years. Median follow-up was 5.0 years (range 2.1-8.2 years). 74% of patients were FIGO (International Federation of Gynecology and Obstetrics) stage I, whereas 7% were stage II, 5% were stage III, and unknown in 14% of the cases. The most common presenting symptoms included abdominal pain (43%) and vaginal bleeding (43%). The majority of patients (38 patients, 62%) were treated with total abdominal hysterectomy and bilateral salpingo-oophorectomy. Five (8%) patients received adjuvant chemotherapy. Sixteen patients (26%) relapsed with a median time to relapse of 5.5 years (0.7-8.1 years). Half of the recurrences (eight patients, 50%) occurred after five years of diagnosis. Five-year overall survival and disease-free survival (DFS) were 93% and 84%, respectively. Factors associated with a high risk of recurrence were the presence of ascites (p=0.000) and elevated preoperative CA 125 level (p=0.048). The overall survival was significantly influenced by the menopausal status (premenopausal 100% vs. postmenopausal 84%; p=0.02), preoperative CA 125 (normal 100% vs. elevated 64%; p=0.005), ascites (present 33% vs. absent 100%; p=0.000), and age (<55 years 100% vs. ≥ 55 years 77%; p= 0.002). CONCLUSION:  This study confirms a good outcome for patients with AOGCT. They require long-term follow-up as late recurrences can occur many years post definitive therapy. The presence of ascites and elevated preoperative CA 125 levels were associated with a higher risk of recurrence and poor prognosis. Outcomes appear unaffected by fertility-sparing surgery or adjuvant chemotherapy.

RESUMO

INTRODUCTION: Gemcitabine is a well-known radiosensitizer. Herein, we tested the efficacy and toxicity of preoperative concurrent infusional gemcitabine and radiotherapy in locally advanced rectal cancer. PATIENTS AND METHODS: This was a phase II, single-arm trial. Eligible patients had a diagnosis of rectal adenocarcinoma with clinical stage T3-T4 and/or nodal involvement, age ≥18 years, and no prior chemotherapy or radiotherapy. Patients received preoperative radiation at a dose of 50.4-54 Gy over 28 days with concurrent infusional gemcitabine administered at a dose of 100 mg/m2 over the course of 24 h weekly for 6 weeks. The primary endpoint was pathological complete response (pCR). RESULTS: Forty patients were recruited. Only one patient did not complete therapy due to death. Eight patients did not undergo surgery, one died, two progressed to nonresectable disease, and five withdrew consent. Five patients progressed prior to surgery, with two having unresectable metastases and three having resectable liver metastases. One was found to have peritoneal metastasis during surgery. Out of the 32 patients who underwent surgery, seven achieved pCR at a rate of 20%. With a median follow-up of 30 months, four additional patients had a distant relapse (one had a subsequent local relapse). The 3-year event-free and overall survival rates were 70% and 85%, respectively. The commonest preoperative grade 3-4 toxicity included lymphopenia (50%), neutropenia (41%), anemia (15%), diarrhea (12%), abdominal pain (12%), and proctitis (8%). CONCLUSION: Concurrent preoperative chemoradiotherapy using infusional gemcitabine for locally advanced rectal cancer achieved an encouraging degree of local control with manageable toxicity.

RESUMO

Introduction: There is evidence for an association between peripheral blood eosinophil count (PBEC) and response to cancer immunotherapy; however, such data is limited in metastatic triple-negative breast cancer (mTNBC). Patients & methods: This report presents patients (n = 14) who received a combination of durvalumab and paclitaxel for mTNBC (NCT02628132). Results: There was a statistically significant correlation (p = 0.028) between an increase in PBEC (>300/mm3) during treatment and response to the combination therapy. Survival analysis showed a statistically significant association between progression-free survival and increased PBEC, after therapy (p = 0.005). A similar trend existed for overall survival, although it did not reach statistical significance (p = 0.167). Conclusion: This is the first study to report on eosinophilia in mTNBC treated with chemoimmunotherapy and supports a role for eosinophils in immunotherapy for mTNBC.


Plain language summary Previous reports have shown that an increase in peripheral blood eosinophil count is associated with a good response to cancer immunotherapy; however, data on this association is limited in a subtype of breast cancer called metastatic triple-negative breast cancer (mTNBC). The eosinophil count in patients who received the combination of an immunotherapeutic agent, durvalumab and a chemotherapeutic agent, paclitaxel, in mTNBC was assessed. There was a statistically significant association between an increase in eosinophils during treatment and the response to therapy. The progression of the disease was slower or less likely to occur in patients with increased eosinophils. This study supports the role of eosinophils in immunotherapy for mTNBC.

RESUMO

PURPOSE: Pazopanib has been approved for treating soft tissue sarcomas (STS) after chemotherapy. We aimed to evaluate the prognostic factors, clinical outcomes, and tolerability of pazopanib in patients with STS. PATIENTS AND METHODS: Forty-five patients treated between June 2015 and August 2019 were reviewed. Clinical outcome was measured by assessing the disease control rate (DCR) using Response Evaluation Criteria in Solid Tumors (version 1.1). Progression-free survival (PFS) and overall survival (OS) were estimated using the Kaplan-Meier method. Adverse effects were assessed using the Common Terminology Criteria for Adverse Events (version 5.0). RESULTS: The median age of patients at diagnosis was 28 (interquartile range (IQR), 23-45) years. Pazopanib was used as the second-line treatment in 46.7% and the subsequent line in 53.3% of patients. The overall DCR was 55.6%, and at 8 and 12 weeks, it was 52.3% and 35.5%, respectively; the median duration of response was 7 (IQR: 2-18) months. Pazopanib-induced hypothyroidism was associated with DCR, with an odds ratio of 7 (95% confidence interval [95% CI: 1.7-27.5], p<0.01). The median PFS and OS were 4.1 (95% CI: 0.85-7.42) and 12.4 months (95% CI: 6.5-18.36), respectively. Hypothyroidism and response to pazopanib, better ECOG PS, histological subtypes desmoid tumor/aggressive fibromatosis (DT/AF), and alveolar soft part sarcoma (ASPS) were favorable prognostic factors for PFS. Hypothyroidism and response to pazopanib were significant favorable factors for OS. There was no statistical difference in the OS between patients using pazopanib as the second-line therapy and those using it as the subsequent-line therapy. CONCLUSION: Pazopanib is an effective treatment for STS. However, it showed variability in the clinical outcome in favor of ASPS and an outstanding response in the DT/AF subtype. Pazopanib-induced hypothyroidism is a good prognostic factor for disease control and is associated with prolonged PFS and OS.

RESUMO

BACKGROUND: Cyclin-dependent kinase 4/6 (CDK 4/6) inhibitors have been a significant breakthrough in the management of hormone receptor-positive, HER2-negative metastatic breast cancer based on the results of several large phase III randomized trials. The most common reported toxicity is myelosuppression due to disease such as leukopenia, neutropenia, and thrombocytopenia. Other toxicities associated with CDK 4/6 inhibitors include mucositis, fatigue, gastrointestinal side effects, hepatic toxicities, and QTc prolongation. Despite a good toxicity profile in pivotal studies, the increased rates of use in clinical practice may show less prevalent but lethal toxicity such as lung injury. CASE PRESENTATION: Here, we describe a female patient with metastatic hormone receptor-positive/human epidermal growth factor 2-negative breast cancer who developed lung toxicity while on ribociclib. DISCUSSION: Lung injury is a possible side effect of CDK 4/6 inhibitors and there is an increasing need to understand the management of this side effect.

RESUMO

BACKGROUND: Nodular lymphocyte-predominant Hodgkin lymphoma (NLPHL) is an uncommon variant of Hodgkin lymphoma. There is limited data on treatment, management of refractory and relapsed disease, and long-term outcome. Many registries or country-wide data reports are unable to provide detailed primary and subsequent management. We are reporting our observation on patient's characteristics, management, and outcome. METHODS: This single-institution retrospective cohort analysis includes NLPHL patients seen from 1998 to July 2019. We used Fisher's exact test, chi-square, and Kaplan-Meier (KM) method for various analyses. RESULTS: Two hundred patients were identified, (6.34% of all the HL). Male:female was 3:1. The median age at diagnosis was 22 years (4-79 years). Stage I-II in 145 (72.5%) cases. One hundred patients (50%) received chemotherapy, 68 (34%) chemotherapy + radiation therapy (RT); 87% of all chemotherapy was ABVD (adriamycin, bleomycin, vinblastine, dacarbazine). Thirteen patients (6.5%) received RT alone and 16 (8%) had surgery alone. Complete response in 82%, partial response in 5.5% and progressive disease in 10.5%. The median follow is 60 months (5-246). Median 5 and 10 years overall survival (OS) is 94.8 and 92.4% (stages I-II, 97.7 and 97.7%, stage III-IV, 94.8 and 92.4%). Median event-free survival (EFS) is 62.3 and 54% respectively (stage I-II, 72 and 64%, stage III-IV, 36.4 and 18.2%). Stage I-II vs III-IV OS (p = < 0.001) and EFS (p = < 0.001) were significant. For stage I-II, 5 year EFS of chemotherapy + RT (83.3%) was superior to chemotherapy alone (60%, p = 0.008). Five year EFS for early favorable (80%), early unfavorable (60%), and advanced (36.4%) was significant (p = < 0.001). Eleven patients (5.5%) had high-grade transformation. Twenty-nine patients underwent HDC auto-SCT, all are alive (28 in remission). 25% of patients had pathologically proved nodal hyperplasia at some point in time. CONCLUSION: OS of NLPHL is excellent and independent of treatment type. EFS is better for chemotherapy + RT than chemotherapy alone. Stem cell transplant in refractory / multiple relapses resulted in excellent disease control. There is a need to identify optimal treatment strategies accordingly to the risk stratification.

RESUMO

BACKGROUND: Familial clustering of lymphoid and/or hematological malignancies (FHM) provides an opportunity to study the responsible genes. The data is limited in patients with lymphoid and hematological malignancies. METHODS: The lymphoma database was used to identify patients seen in our institution from 1998 to 2019 with nodular lymphocyte-predominant Hodgkin lymphoma (NLPHL). We studied FHM by collecting detailed history of any malignancy in the family (FM). RESULTS: Two hundred NLPHL patients were identified. Contacting was not possible in 30 patients due to no response to the phone calls (22) and death [1]. 170/200 patients were interviewed; represented 167 families (3 patients with a family member with NLPHL). These 170 patients provided information about 8225 family members. These 167 families had a total of 329 family members with 334 malignancies (including 167 NLPHL patients and 5 members with 2 malignancies each). Of these 167 patients, 77 (46.1%) had no FM while 90 (53.9%) patients had a positive FM; 162 family members with 167 malignancies. Among these 167 families, 31 families (18.6%) had members with FHM +/- solid cancers. These 31 families had 35 family members (25 males:10 females) with 16 lymphomas: diffuse large B cell lymphoma [2], follicular center cell lymphoma [3], chronic lymphocytic leukemia/small lymphocytic lymphoma [3], non-Hodgkin lymphoma [2], classical HL [2], and NLPHL [4]. Total of 8 leukemia: acute lymphoblastic leukemia [4], acute myeloid leukemia [3], and leukemia - no subtyping [5]. These 35 FHM members are 1st [6], 2nd (16), and 3rd [7] degree relatives of 31 NLPHL patients. There are 4 families with NLPHL in family members; all these 8 NLPHL patients are male and are alive. The median total number of 1st + 2nd +3rd degree members are 81. The decrease in the age of diagnosis from 1st generation to the 2nd generation (anticipation) was noted in 13/17 patients; 2nd generation median age at diagnosis was 29.7 years vs 1st generation age 53 years (developed malignancy 23.3 years earlier). CONCLUSION: FHM is frequent in NLPHL. This study provided us many important insights for planning future studies in terms of interviewing technique, time, and resource allocation and genetic testing.

RESUMO

PURPOSE: The correlation between the preoperative neutrophil-to-lymphocyte ratio (NLR) and Oncotype DX® (ODX) recurrence score (RS) has not yet been established. We aimed to investigate the association between NLR and ODX RS in patients with hormone receptor-positive (HR+) and human epidermal growth factor receptor 2-negative (HER2-) early-stage breast cancer (BC). PATIENTS AND METHODS: This retrospective study included consecutive patients with HR+/HER2-, node-negative primary BC who underwent surgical tumor resection from 2011 to 2019. Receiver operating characteristic curve analysis was used to obtain an optimal NLR cutoff value. Logistic regression analyses were used to estimate associations between various parameters and ODX RS. Furthermore, the factors significantly associated with the ODX RS in multivariable analysis were incorporated in a separate model and estimated using logistic regression. RESULTS: A total of 160 patients were enrolled. The optimal preoperative NLR cutoff was 2.15. Multivariable analysis revealed that NLR and tumor grade (G1/G2 vs G3) were independent predictive factors of high RS cutoff (≥26). Moreover, including the two variables yielded a stronger association; patients with low NLR and low-grade tumors were unlikely to have high RS (≥26; odds ratio [OR] = 0.03, 95% confidence interval [CI]: 0.006-0.154; p < 0.001). Conversely, the presence of any of the following factors made patients unlikely to have low RS (<16; OR = 0.34, 95% CI: 0.16-0.73; p = 0.006): high NLR, high grade, or high Ki-67 levels (>20). CONCLUSION: NLR is a promising independent predictor of RS. Furthermore, in addition to tumor grade and Ki-67 level, they together are also a potential indicator of high and low RS. However, further studies are required to validate this hypothesis.

RESUMO

BACKGROUND: Surgical resection of metastatic disease in patients with initially non-resectable colorectal cancer (CRC) has improved overall survival. Intensified chemotherapy regimens have increased the probability of converting unresectable metastasis to resectable. Here, we report the result of combining intensive chemotherapy (triplet) and surgical resection of metastatic lesions in patients with metastatic CRC. PATIENTS AND METHODS: Patients with unresectable metastatic CRC were enrolled in phase I/II trial of triplet chemotherapy consisting of capecitabine, oxaliplatin, irinotecan, and bevacizumab. Patients were given 5-8 cycles induction chemotherapy of the above regimen followed by maintenance capecitabine and bevacizumab until disease progression, unacceptable toxicity, or patient request. All patients were assessed at a multidisciplinary conference for possible surgical resection of their metastatic disease at the time of inclusion in the trial and 2 monthly intervals thereafter. Patients who underwent R0 resection of their metastatic disease received adjuvant oxaliplatin and capecitabine to complete a total of 6 months of chemotherapy. RESULTS: Fifty-three patients were enrolled. The median age was 52 years (range 23-74), 29 (55%) were males, ECOG PS 0-1 was 13 (66%), 11 (42%) had a right-sided tumor, 29 (55%) had resection of their primary tumor, 22 (42%) had a single metastatic site, and 8 (15.1%) had a liver-limited disease. Thirteen patients (24.5%) underwent surgical resection of residual metastatic disease +/- the primary tumor with 10 (18.9%) of them were R0. The surgical group had a higher incidence of males compared to the non-surgical group (69.3% vs 47.2%, p = 0.2), equal performance status, lower median number of metastatic sites (1 vs 2, p = 0.09), higher mutant Kras (53.8% vs 34.2%, p = 0.3), and higher response rate (84.6% vs 56.2%, p = 0.3). With a median follow-up duration of 89 months, the median PFS for the whole group was 16.1 months [95% confidence interval (CI) 9.1-20] and the median OS was 28.2 months (95% CI 22.5-53.3). The median PFS for the surgery group was 18.9 months (95% CI 12.6-not reached) compared to 9.6 months (95% CI 7.0-18.3) for the non-surgical group, log-rank p = 0.0165. The median OS for both groups was not reached (95% CI 53.3-not reached) and 23.2 months (95% CI 17.0-28.4) respectively, log-rank p = 0.0006. Five-year PFS and OS for the surgery group were 46.2% and 67.6% respectively. CONCLUSIONS: Patients with unresectable metastatic CRC and fit for triplet chemotherapy should have the benefit of combining this intensified regimen and surgical resection of their metastatic disease if possible.

RESUMO

PURPOSE: Antiangiogenic tyrosine kinase inhibitors have been the mainstay first-line therapy for metastatic renal cell carcinoma (mRCC). We reviewed the efficacy of first-line therapy with sunitinib in patients with mRCC in an Arab population. METHODS: Medical records of patients with mRCC treated at a tertiary care center in Saudi Arabia, during the period from 2007 to 2016, were reviewed. Demographic data, treatment received, response, and prognostic factors were analyzed. RESULTS: Fifty-five patients who received sunitinib were identified. The median age was 60 years (range, 18 to 78 years), and 42 of the 55 patients were men (76.3%). International Metastatic RCC Diagnostic Consortium prognostic scores for favorable/intermediate/poor were 14.5%/43.6%/38.2%, respectively. The median performance status was 1, and the median Charlson comorbidity index score was 9. Thirty-seven patients (67.2%) had cytoreductive nephrectomy. Thirty-seven patients (67.2%) had clear cell histology. Twenty-two patients (40%) underwent dose reduction. Twenty-seven patients (49%) received second-line therapy, and seven patients (12.7%) received third-line therapy. Response rates were complete response in one patient (1.8%), partial response in 17 (30.9%), stable disease in 10 (18.1), and disease progression in 20 (36.3%). Progression-free survival (PFS) and overall survival (OS) were 6.0 and 24.7 months, respectively. Univariate analysis showed statistically improved PFS for dose reduction (P = .015) and the development of hypothyroidism (P = .03). It also showed statistically improved OS for dose reduction (P = .035), hypothyroidism (P = .0002), and cytoreductive nephrectomy (P = .0052). Multivariate analysis showed statistically improved PFS for dose reduction (P = .01) and OS for development of hypothyroidism (P = .007). CONCLUSION: Our data for sunitinib in mRCC show significantly lower PFS than expected. The absence of prognostic value of the International Metastatic RCC Diagnostic Consortium scoring system and pathologic subtype warrant further investigation and possible inclusion of genetic scoring in this ethnic group of patients.

RESUMO

BACKGROUND Metaplastic breast cancer (MPBC) is a rare subtype of breast cancer that is difficult to manage and is resistant to therapy. Immunotherapy is becoming a promising option for care of several types of cancers including triple negative breast cancer. CASE REPORT We present a case of a patient with chemo-refractory metastatic metaplastic-type of breast cancer with failures to 3 active lines of chemotherapy. The patient achieved a complete and sustained response to chemo-immunotherapy combination with acceptable tolerability and minimal adverse events. The treatment was a combination of anti-PD-L1 antibody (durvalumab) immunotherapy in combination with the chemotherapeutic agent, paclitaxel. CONCLUSIONS This is the first case reporting the successful use of durvalumab and paclitaxel combination for treatment of triple negative breast cancer in general, and in metastatic MPBC in specific.
