Linfoma anaplásico de grandes células T associado ao uso de implantes (BIA-ALCL): relato de caso / Implant-associated anaplastic large T-cell lymphoma (BIA-ALCL): case report

Reconhecido pela Organização Mundial de Saúde em 2016, o linfoma anaplásico de grandes células associado ao implante mamário (BIA-ALCL) é um subtipo incomum de linfoma não Hodgkin de células T, que se desenvolve após a inserção de próteses mamárias. A doença é uma afecção rara que afeta cerca de uma a cada 30.000 pessoas com implante mamário texturizado. As principais manifestações clínicas são o seroma tardio, assimetria mamária, massa e contratura capsular, com frequência mais elevada do primeiro. O explante da prótese com capsulectomia total pode ser suficiente para tratar o ALCL, com ressecções estendidas a locais adjacentes, quando necessário. Entretanto, em alguns casos, é realizada a radioterapia e/ou quimioterapia adjuvante. Conclui-se que, para um diagnóstico precoce e um tratamento efetivo, mulheres com seroma de aparecimento súbito e tardio deverão realizar exames complementares para a exclusão dessa afecção, mesmo com tempo inferior à média de desenvolvimento, que é de cerca de 10,6 anos.

Recognized by the World Health Organization in 2016, breast implant-associated anaplastic large cell lymphoma (BIA-ALCL) is an uncommon subtype of T-cell non-Hodgkin lymphoma that develops after the insertion of breast implants. The disease is a rare condition that affects approximately one in every 30,000 people with textured breast implants. The main clinical manifestations are late seroma, breast asymmetry, mass, and capsular contracture, with a higher frequency of the former. Explantation of the prosthesis with total capsulectomy may be sufficient to treat ALCL, with resections extended to adjacent sites when necessary. However, in some cases, adjuvant radiotherapy and/or chemotherapy is performed. It is concluded that, for an early diagnosis and effective treatment, women with sudden and late-onset seroma should undergo additional tests to exclude this condition, even with a shorter development time than the average, which is around 10.6 years.

Applicability and feasibility of robot-assisted cystectomy and intracorporeal urinary diversion in a patient with right renal pelvic ectopia

ABSTRACT Background: The ectopic pelvic kidney, a common renal anomaly, is often smaller and malformed, with a shorter and sometimes tortuous ureter (1). Muscle-invasive bladder cancer (MIBC), constituting 15-25% of bladder cancer cases (2), mandates radical cystectomy with a 50% 5-year survival rate (2). Despite the growing use of robot-assisted radical cystectomy (RARC) (3, 4), there is limited data on its application in ectopic kidneys. Only one RARC case has been reported (5), in contrast to numerous open radical cystectomies (1, 6) involving an ectopic kidney. Patient and methods: After being diagnosed with T2 high-grade urothelial carcinoma, the 66-year-old patient, previously treated with multiple transurethral resections and adjuvant BCG therapy, received neoadjuvant chemotherapy. Preoperative staging CT revealed a 2.6 x 2.2 cm bladder neoformation and an ectopic right pelvic kidney. Results: Using the da Vinci Surgical System, radical cystectomy with ileal conduit (sec Wallace II) and lymphadenectomy were performed. During the demolition phase, the shorter right ureter was dissected with care to avoid damage to the renal pedicle. The reconstructive phase included intracorporeal urinary diversion (ICUD) and uretero-ileal anastomosis, facilitated by the favorable position of the kidney. The 8-hour console surgery resulted in minimal blood loss. Discharged on day 16 due to COVID-19, the patient exhibited positive outcomes. A 2-month CT follow-up revealed no cancer recurrence, metastasis, hydronephrosis, and complete regression of the lymphocele. Imaging follow-up continues without postoperative adjuvant chemotherapy. Conclusion: Robotic surgery with intracorporeal urinary diversion holds potential for right-sided pelvic kidney cases, but additional studies are necessary for validation.

Robot-assisted retroperitoneal lymph node dissection as primary treatment for stage II seminoma germ cell tumor

ABSTRACT Introduction: Historically, therapeutic avenues for patients with clinical stage II seminoma germ cell tumors (SGCT) were confined to radiotherapy and chemotherapy. While survival rates with these modalities are commendable, both entail substantial long-term morbidities. Furthermore, this youthful patient cohort exhibits elevated rates of secondary malignancies, surfacing decades post-successful primary cancer treatment (1). Recently, retroperitoneal lymph node dissection (RPLND) has emerged as a primary treatment consideration for individuals with low-volume metastatic seminoma (2-4). However, there is a dearth of video documentation illustrating the robotic assisted (RA) bilateral approach (5- 7). Methods: We present the case of a 24-year-old male who underwent prior left orchiectomy for seminoma (pT1b). Despite negative serum tumor markers, a 1.7 x 1.4cm lymph node enlargement was identified in the aortic bifurcation after 4 months, classifying the patient as stage IIA per the IGCCCG risk classification. Subsequently, a RA bilateral template RPLND was performed due to the patient's refusal of chemotherapy, citing concerns about offspring. Results: The surgery was performed, incorporating nerve sparing techniques, lasting 4h13minutes, an estimated bleeding rate of 400ml, without intraoperative complications. The patient was discharged within 24 hours of the procedure, following a prescribed low-fat diet. Conclusion: The patient experienced postoperative well-being, painlessness, and resumed work three weeks post-procedure. Preserved ejaculation was noted, and adjuvant therapy was performed with 2 cycles of EP due to the anatomopathological result. The feasibility of robotic primary RPLND for SGCT was demonstrated, showing reduced postoperative pain and early hospital discharge. Further studies are necessary to validate our findings regarding oncological, safety, and functional outcomes.

ABSTRACT Background: Gastric cancer (GC) represents a public health problem in Colombia and worldwide. Since most patients are at advanced stages at the time of diagnosis. it is necessary to develop management strategies as conversion therapy (CT). Objective: The aim of this study was to estimate the results of CT for treating patients with advanced and GC at Instituto Nacional de Cancerología de Colombia (INC). Material and methods: We included patients with incurable gastric cancer who underwent induction chemotherapy and intended curative surgery between 2010 and 2021. The clinical and pathological data and survival of the patients included were retrospectively reviewed. Overall survival (OS) was calculated from the time of initiation of chemotherapy until the date of death. Survival functions were estimated using the life table and Kaplan-Meier methods. and survival curves at 3 and 5 years were constructed. Results: 23 patients were analyzed; mean age was 56 years. and 17 (74%) were men. The most common criterion indicating unresectability was a T4b tumor in 13 cases (56.5%). All the patients underwent CT. Median follow-up was 28 months. Eleven patients developed disease recurrence (52%). Median survival was 41.2 months. and 3- and 5-year OS was 57.7% and 38.5%. respectively. Conclusions: CT provided an acceptable OS rate for selected patients with incurable advanced GC. This strategy requires an adequate selection of patients and multidisciplinary management in reference oncology centers.

Cáncer Gástrico Bifocal con Linfonodos Negativos en un Paciente con Cirrosis Hepática / Bifocal Gastric Cancer with Negative Lymph Nodes in a Hepatic Cirrhosis Patient

El cáncer gástrico (CG), es la primera causa de muerte por cáncer, en hombres, y la tercera en mujeres, en Chile. No obstante ello, el CG bifocal (CGB) es una situación poco frecuente. El objetivo de este manuscrito fue reportar un caso de CGB, con linfonodos negativos en un paciente con cirrosis hepática, que fue intervenido quirúrgicamente; y revisar la evidencia existente respecto de sus características morfológicas, terapéuticas y pronósticas. Caso clínico: Hombre de 74 años diabético, hipertenso, insuficiente cardíaco y cirrótico; portador de CGB (subcardial y antro-pilórico), diagnosticado por endoscopia y con confirmación histológica de ambas lesiones; operado en Clínica RedSalud Mayor Temuco en septiembre de 2023. En el intraoperatorio se verificó además la coexistencia de una lesión de aspecto metastásico en el segmento III del hígado, y adhesión de la región antro-pilórica a la vesícula biliar. Se realizó gastrectomía total, linfadenectomía D2, esófago-yeyuno anastomosis término-lateral, resección segmentaria hepática (segmento III) y colecistectomía. El paciente permaneció 6 días en la UCI debido a que desarrolló insuficiencia hepática (encefalopatía leve y ascitis). Se alimentó vía enteral por sonda naso-yeyunal. Posteriormente inició alimentación oral progresiva, la que fue bien tolerada. Completó 11 días de hospitalización en servicio médico-quirúrgico, donde mejoró actividad neurológica, hasta su alta domiciliaria. Actualmente, lleva dos meses desde su operación, se encuentra en buenas condiciones generales, y el Comité Oncológico decidió no dar quimioterapia adyuvante. Se presenta un caso inusual de CG de tipo bifocal, respecto de lo cual hay escasa información disponible. Se logró realizar cirugía con intención curativa en un paciente de alto riesgo, con un resultado exitoso.

SUMMARY: Gastric cancer (GC) is the first cause of death from cancer in men, and the third one in women, in Chile. However, a bifocal GC (BGC) is uncommon. The aim of this study was to report a case of CGB, with negative-lymph nodes in a patient with liver cirrhosis, who underwent surgery; and review the existing evidence regarding its morphological, therapeutic and prognostic characteristics. Clinical case: A 74-year-old male patient with a medical history of diabetes, hypertension, congestive heart failure, and cirrhosis underwent surgical intervention for GC located in subcardial and antro- pyloric regions. The diagnosis was established via endoscopy and confirmed histologically. Surgery was performed at the RedSalud Mayor Temuco Clinic in September 2023. During intraoperative assessment, the coexistence of a lesion with metastatic-like characteristics in segment III of the liver was also verified, along with adhesions between the antro-pyloric region and the gallbladder. Surgical approach encompassed total gastrectomy, D2 lymphadenectomy, esophago-jejunostomy, segmental hepatic resection, and cholecystectomy. Subsequently, the patient required a six-day stay in ICU due to the development of hepatic insufficiency, characterized by mild encephalopathy and ascites. Enteral nutrition was administered via a naso-jejunal tube, followed by a gradual transition to oral feeding, which was well-tolerated. The patient completed an 11-day hospitalization period in the medical-surgical ward, during which his neurological function improved significantly, resulting in his discharge. At present, 2 months post-surgery, the patient remains in satisfactory general health, and the Oncology Committee decided not to proceed with adjuvant chemotherapy. This case represents a rare instance of bifocal GC, for which there is limited available literature. Surgical intervention with curative intent was successfully carried out in a high-risk patient, yielding a positive outcome.

Probiotics intervention in colorectal cancer: From traditional approaches to novel strategies / 中华医学杂志(英文版)

The intestine harbors a large population of microorganisms that interact with epithelial cells to maintain host healthy physiological status. These intestinal microbiota engage in the fermentation of non-digestible nutrients and produce beneficial metabolites to regulate host homeostasis, metabolism, and immune response. The disruption of microbiota, known as dysbiosis, has been implicated in many intestinal diseases, including colorectal cancer (CRC). As the third most common cancer and the second leading cause of cancer-related death worldwide, CRC poses a significant health burden. There is an urgent need for novel interventions to reduce CRC incidence and improve clinical outcomes. Modulating the intestinal microbiota has emerged as a promising approach for CRC prevention and treatment. Current research efforts in CRC probiotics primarily focus on reducing the incidence of CRC, alleviating treatment-related side effects, and potentiating the efficacy of anticancer therapy, which is the key to successful translation to clinical practice. This paper aims to review the traditional probiotics and new interventions, such as next-generation probiotics and postbiotics, in the context of CRC. The underlying mechanisms of probiotic anti-cancer effects are also discussed, including the restoration of microbial composition, reinforcement of gut barrier integrity, induction of cancer cell apoptosis, inactivation of carcinogens, and modulation of host immune response. This paper further evaluates the novel strategy of probiotics as an adjuvant therapy in boosting the efficacy of chemotherapy and immunotherapy. Despite all the promising findings presented in studies, the evaluation of potential risks, optimization of delivery methods, and consideration of intra-patient variability of gut microbial baseline must be thoroughly interpreted before bench-to-bedside translation.

Establishment of pharmaceutical care pathway based on the problems related to chemotherapy / 中国药房

OBJECTIVE To design pharmaceutical care pathway for the problems related to chemotherapy， and to evaluate whether it contributes to the detection and intervention of drug-related problems （DRPs） in chemotherapy patients. METHODS The pharmaceutical care pathway table and flow charts were constructed and implemented by pharmaceutical care practice experience. The patients who were admitted to our hospital for chemotherapy before and after the implementation of the pharmaceutical care pathway were divided into control group （before the implementation，60 cases） and observation group （after the implementation，64 cases）， respectively； the relevant medical records of patients in the control group were extracted to evaluate DRPs， and pharmaceutical care of chemotherapy-related problems was performed for patients in observation group to extract DRPs. The basic condition， chemotherapy condition， DRPs classification and intervention status， adverse reactions induced by chemotherapy， PCNE classification of DRPs， occurrence time of DRPs， and drug classes related to DRPs were compared between 2 groups. RESULTS There was no statistical significance in the basic situation， chemotherapy regimen and chemotherapy drug category between the two groups （P＞0.05）. DRPs occurred in 46 and 37 patients in control group and observation group， respectively. In both groups， DRPs mainly occurred during chemotherapy， and mainly in the early stage of chemotherapy. Using the new pathway， the detection of DRPs significantly increased from 52.17% in the control group to 91.89% in the observation group （P＜0.05）. The successful intervention rate of DRPs was significantly increased from 32.61% in the control group to 72.97% in the observation group （P＜ 0.05）. The incidence of adverse drug reactions significantly decreased from 28.33% in the control group to 12.50% in the observation group（P＜0.05）. The main problem type of DRPs in the control group was treatment effectiveness， which mainly involved adjuvant antitumor drugs， mainly due to the use of adjuvant anti-tumor drugs for off-label prescribing； that of the observation group was treatment effectiveness and treatment safety， which mainly involved vomiting drugs， mainly due to insufficient medication to prevent nausea and vomiting caused by chemotherapy. CONCLUSIONS The implementation of the pathway helps clinical pharmacists to detect and intervene in DRPs among chemotherapy patients， and reduces the occurrence of chemotherapy-induced adverse reactions.

Value of a nomogram model in early recurrence of pancreatic ductal adenocarcinoma after laparoscopic pancreaticoduodenectomy / 临床肝胆病杂志

ObjectiveTo investigate the risk factors for early tumor recurrence after laparoscopic pancreaticoduodenectomy （LPD） in patients with pancreatic ductal adenocarcinoma （PDAC）， and to establish a predictive model. MethodsA retrospective analysis was performed for the clinical data of 240 PDAC patients who underwent LPD in The First Hospital of Jilin University from April 2016 to July 2022， with early postoperative tumor recurrence （time to recurrence ≤12 months） as the study outcome. The patients were randomly divided into training group with 168 patients and validation group with 72 patients at a ratio of 7∶3. In the training group， there were 70 patients （41.67%） with early postoperative recurrence and 98 （58.33%） without early recurrence， and in the validation group， there were 32 （44.44%） with early postoperative recurrence and 40 （55.56%） without early recurrence. The chi-square test or the Fisher’s exact test was used for comparison of categorical data between groups； a logistic regression analysis was used to investigate the risk factors for early postoperative recurrence； the receiver operating characteristic （ROC） curve and the area under the ROC curve （AUC） were used to evaluate the discriminatory ability of the model， with AUC>0.75 indicating that the model had adequate discriminatory ability. The Bootstrap resampling method was used for validation after 1 000 times of random sampling， and the model was validated again in the validation group. The calibration curve and the Hosmer-Lemeshow goodness-of-fit test were used to evaluate the degree of calibration， and the decision curve analysis was used to evaluate clinical practicability. ResultsThe univariate and multivariate analyses showed that preoperative CA19-9 level≥37 U/mL （odds ratio ［OR］=6.265， 95% confidence interval ［CI］： 1.938‍ ‍—‍ ‍20.249， P<0.05）， maximum tumor diameter >3 cm （OR=10.878， 95%CI： 4.090‍ ‍—‍ ‍28.932， P<0.05）， poor tumor differentiation （OR=3.679， 95%CI： 1.435‍ ‍—‍ ‍9.433， P<0.05）， lymph node metastasis （OR=0.209， 95%CI： 0.080‍ ‍—‍ ‍0.551， P<0.05）， and absence of adjuvant chemotherapy after surgery （OR=0.167， 95%CI： 0.058‍ ‍—‍ ‍0.480， P<0.05）. A nomogram model was constructed based on these factors； the ROC curve analysis showed that the model had an AUC of 0.895 （95%CI： 0.846‍ ‍—‍ ‍0.943， P<0.001）， and the calibration curve and the Hosmer-Lemeshow test showed that the model had a good degree of calibration （P=0.173）. The decision curve analysis showed that the nomogram had a good clinical application value. ConclusionPreoperative CA19-9 level ≥37 U/mL， maximum tumor diameter >3 cm， poor tumor differentiation， lymph node metastasis， and absence of adjuvant chemotherapy after surgery are independent risk factors for the early recurrence of PDAC after LPD， and the nomogram model established based on these factors can effectively predict early postoperative recurrence.

Research Progress on Dual Role of Autophagy in Cancer and Intervention of Traditional Chinese Medicine / 中国实验方剂学杂志

With the change in environmental pollution and lifestyle， the incidence and mortality of cancer are increasing year by year， which is a serious threat to human life and health. Autophagy is a process in which eukaryotic cells use lysosomes to degrade cytoplasmic proteins and damaged organelles under the regulation of autophagy-related genes. It plays a dynamic inhibiting or promoting role in the occurrence and development of cancer and is involved in the regulation of tumor formation， proliferation， metastasis， and response to anticancer therapy. With the deepening of the research on the mechanism of cancer， a variety of cancer treatment methods have been established， such as chemotherapy， radiotherapy， surgery， immunotherapy， and gene therapy. Pharmacological or genetic inhibition of autophagy has been shown to enhance the lethal effect of various anticancer treatments on tumor cells， suggesting that inhibition of autophagy is an effective sensitization strategy in cancer therapy. Meanwhile， over-stimulation of autophagy may also provide a new method for the treatment of drug-resistant cancer cells with high apoptotic thresholds. As a treasure of Chinese culture， traditional Chinese medicine plays an important role in the adjuvant treatment of cancer with its advantages of multi-target， multi-pathway， and small side effects. In recent years， many positive results have been achieved in the study of natural autophagy regulatory factors of traditional Chinese medicine in cancer， and they have been widely verified in different autophagy regulatory models. This article outlines the mechanism of autophagy， summarizes the dual regulatory role of autophagy in tumor biology， and collects relevant studies published in the databases of China National Knowledge Infrastructure (CNKI） and Wanfang Data for nearly 10 years that affect the role of tumorigenesis and development by regulating autophagy. The article also collates autophagy rules of tumor cells induced by traditional Chinese medicine and its active ingredients， so as to provide a certain reference for the research on the development and application of anti-tumor drugs.

Survival Analysis and Prognostic Factors for Peri-ocular Malignancies in Malaysia

@#Introduction: This study aims to determine the prognostic factors and survival outcomes of patients that underwent this surgery. Method: A retrospective review of 43 patients who underwent exenteration for periocular malignancies over a 14-year period was carried out. Patient demographics, tumour histology, treatment details, surgical margins’ status and post-operative survival were recorded. The survival outcome examined was the overall survival (OS) rate. Cox regression and Kaplan-Meier analysis were used to evaluate post-exenteration survival. Results: In total, 20 females and 23 males with a median age of 62 ± 17.3 years were identified. The most common indication for exenteration was basal cell carcinoma (20.9%), followed by squamous cell carcinoma (18.6%), adenocystic carcinoma (14%), malignant melanoma (14%) and sebaceous gland carcinoma (11.6%). The independent predictors for worse OS on multivariate analysis were Chinese ethnicity (adjusted hazard ratio [aHR] 4.95, p =0.017), sebaceous gland carcinoma (aHR 57.61 p=0.006), adenocystic carcinoma (aHR 45.87, p=0.008), clear surgical margins (aHR 5.41, p=0.025), receiving only chemotherapy (aHR 169.13, p=0.004), and receiving both adjuvant chemotherapy and radiotherapy (aHR 41.51, p=0.010). Conclusion: We recommend targeted public health initiatives for Chinese patients due to their increased mortality risk from peri-ocular malignancies. In addition, we advise comprehensive adjuvant therapy for all patients regardless of whether a clear surgical margin is achieved. Basal cell carcinoma and adenocystic carcinoma may also benefit from genetic research. We advocate more training for ophthalmologists to identify periocular malignancies earlier for better treatment options and increased chances of survival.

Clinicopathological features of gastric alpha-fetoprotein-producing adenocarcinoma with SWI/SNF complex deletion / 中华病理学杂志

Objective: To investigate the clinicopathological features and treatment of gastric alpha-fetoprotein (AFP)-producing adenocarcinoma with SWI/SNF complex deletion. Methods: Four cases of gastric AFP-producing adenocarcinoma with SWI/SNF complex deletion diagnosed in Zhongshan Hospital of Fudan University from January 2021 to December 2022 were collected, and their histomorphological characteristics, immunohistochemical (IHC), in situ hybridization of Epstein-Barr virus-encoded RNA (EBER), next-generation sequencing results, clinicopathological features and treatment were summarized, and literature review was conducted. Results: Among the 4 patients, there were three males and one female. They presented with abdominal pain, belching and melena. Serum AFP was significantly elevated in three patients, and endoscopy showed ulcerative lesions. Microscopically, the tumor cells showed mainly diffuse flaky or nest-like growth and typical characteristics of hepatoid adenocarcinoma. In two cases there were adenoid growth, and the tumor cells in these areas possessed clear cytoplasm, suggesting enteroblastic differentiation. The tumor cell nuclei were pleomorphic with large nucleoli and brisk mitoses. The IHC results showed that the tumor cells expressed AFP, GPC3 and SALL4, and there was retained expression of broad-spectrum keratin (CKpan) and E-cadherin. IHC detection of SWI/SNF complex subunits, namely INI1 (SMARCB1), BRG1 (SMARCA4), BRM (SMARCA2), ARID1A protein was performed. In all four cases the hepatoid adenocarcinoma region and enteroblastic differentiation region showed SMARCA2 deletion, and one case with enteroblastic differentiation also showed ARID1A deletion. SMARCB1 and SMARCA4 deletions were not seen. All the four cases were diffusely positive for p53 protein, and the Ki-67 proliferation index was 80%-90%. There were no mismatch repair deletion detected; one cases showed HER2 was strongly positive (3+), and EBER was negative. None of the four cases had mutations in the SWI/SNF complex-related subunits detected by next-generation sequencing. Among the four patients, two underwent palliative surgery due to distant metastasis at the time of surgery, two underwent radical resection. Postoperative adjuvant chemotherapy was given to three patients. Conclusions: AFP-producing adenocarcinoma is a rare subtype of gastric cancer, which can be combined with SWI/SNF complex deletion, and the pathomorphological manifestations are different from the classical SWI/SNF complex deletion of undifferentiated carcinoma with rhabdoid phenotype.

Are depression and poor sleep quality a major problem in Turkish Women receiving chemotherapy for breast cancer?

SUMMARY OBJECTIVE: The aim of this study was to evaluate depression and sleep quality in Turkish women receiving neoadjuvant or adjuvant chemotherapy for breast cancer and investigate their relationship. METHODS: This cross-sectional, descriptive, and analytical study included 183 patients who received chemotherapy for non-metastatic breast cancer. Data were collected using the Beck Depression Inventory-II, the Pittsburgh Sleep Quality Index, and a disease-related/sociodemographic information form. RESULTS: The mean age of the participants was 50.2 years, and 50.3% were in menopause. The mean Beck Depression Inventory-II score was 19.64±10.4. Mild depression was detected in 25.7% (n=47) of the women, and moderate or severe depression in 55.2% (n=101). The mean global score of sleep quality was found to be 8.28±2.62, and the majority of the participants (79.7%, n=146) had poor sleep quality. There was a positive correlation (p<0.001, r=0.43) between depression and sleep quality scores. While a negative correlation was found between depression scores and age (p<0.001, r=0.26), the surgical procedure performed did not significantly affect depression scores (p=0.705). Additionally, depression scores were positively correlated with sleep duration (p<0.001, r=0.42) and sleep latency (p=0.01, r=0.48). CONCLUSION: Very high rates of depression and poor sleep quality were detected among Turkish women receiving neoadjuvant or adjuvant chemotherapy for breast cancer. The entire healthcare team involved in the treatment process should take this relationship into consideration and use the necessary preventive and therapeutic methods.

Malignant phyllodes tumor of the breast in ayoung patient ­ case report

Phyllodes tumor (PT) is an uncommon form of breast tumor. It occurs most commonly in women aged 35 to 65 years. The benign form represents about 85­90% of cases and only 10­15% of PTs are malignant. Clinically and radiologically, malignant phyllodes tumor (MPT) presents as regular, well-delimited, mobile nodules that are difficult to distinguish from fibroadenomas of the breast. The most important differential diagnoses of MPT include fibroadenoma, metaplastic carcinoma, and sarcoma. The prognosis of MPT exhibits a higher frequency of local recurrence and metastatic rate with larger tumors and inadequate surgical margins. The case presented here refers to a 24-year-old female patient, with a vast tumor in the right breast, with rapid and progressive growth, associated to local pain, and histological diagnosis of MPT. Surgery was the initial treatment, followed by adjuvant chemotherapy and radiotherapy. The purpose of this article was to report an atypical case of MPT of the breast in a very young woman as well as to make a brief literature review on this infrequent and dangerous disease. (AU)

Primary basal cell carcinoma of the caruncle: case report and review of the literature

ABSTRACT We present a rare case of primary caruncle basal cell carcinoma (BCC), a condition with limited occurrences. Our patient, an 80-year-old woman without prior ocular pathological history, presented a 2x2mm pedunculated blackish nodular lesion on the caruncle of her left eye, without local conjunctival or cutaneous involvement. Histological analysis following complete excision confirmed the presence of basal cell carcinoma within the caruncle. Over a span of 30 months, no recurrence has been observed. While scant cases are documented in the literature, we conducted a review of these instances. Despite its infrequent manifestation, this condition should be taken into account when evaluating caruncular tumors, given its tendency to invade the orbit. Complete excision with free surgical margins is the treatment of choice, and adjuvant radiotherapy or chemotherapy might be considered.

Metástasis Pancreática Metacrónica de un Carcinoma de Células Renales. Reporte de un Caso / Metachronic Pancreatic Metastasis of a Renal Cell Carcinoma. Case Report

El carcinoma de células renales (CCR) a nivel mundial presenta una incidencia de 431.288 casos anuales, causando 179.368 muertes en 2020. Sin embargo, a pesar de su incidencia, el desarrollo de metástasis pancreática (MP) de un RCC es un hecho inusual. El objetivo de este manuscrito fue reportar el caso de una paciente con una MP metacrónica de un CCR. Se trata de una paciente de 56 años, sexo femenino, nefrectomizada derecha hace 132 meses por un CCR, en adyuvancia con inmunoterapia. En un control imagenológico de rutina, se le pesquisó una lesión de aspecto tumoral en el cuerpo y cola del páncreas. Se intervino quirúrgicamente, realizándose una pancreatectomía córporo-caudal con preservación esplénica. Evolucionó de forma satisfactoria, sin complicaciones, siendo dada de alta al 4º día de su cirugía. El informe del estudio de la pieza operatoria con estudio inmunohistoquímico concluyó que se trataba de una MP de CCR. La paciente se encuentra en buenas condiciones generales y reinició quimioterapia con anticuerpos monoclonales. El seguimiento frecuente y prolongado de pacientes con antecedentes de CCR, facilita un diagnóstico y tratamiento oportuno de MP facilitando el mejor pronóstico de los pacientes, con tasas más altas de supervivencia.

SUMMARY: Renal cell carcinoma (RCC) worldwide has an incidence of 431,288 cases per year, causing 179,368 deaths in 2020. However, despite its incidence, the development of pancreatic metastasis (MP) from RCC is unusual. The aim of this manuscript was to report the case of a patient with a PM of a RCC. This is a 56-year-old female patient, underwent right nephrectomy 132 months earlier for RCC. While she was in adjuvant immunotherapy, in a routine imaging control, it was found a tumor lesion in the body and the tail of the pancreas. So, she underwent surgery, performing a corpora-caudal pancreatectomy with splenic preservation. Postoperative evolution was correct, without complications, and she was discharged on the 4th day after surgery. The report of the study of the surgical piece with an immunohistochemical study included, conclusive of PM of RCC. Currently, the patient is in good general condition and restarted chemotherapy with monoclonal antibodies. Frequent and prolonged follow-up of patients with a history of RCC facilitates timely diag- nosis and treatment of PM, facilitating the best prognosis for patients, with higher survival rates.

Carcinoma neuroendocrino de canal anal: presentación de un caso y revisión bibliográfica

Introducción: Los carcinomas neuroendocrinos (NEC) de canal anal son neoplasias extremadamente raras, representando del 1 a 1,6% de la totalidad de los tumores neuroendocrinos (NET). Suelen ser poco diferenciados, muy agresivos y con alta tendencia a metastatizar. Caso clínico: Mujer de 52 años diagnosticada de fisura anal. Durante la esfinterotomía lateral interna (ELI) se evidencia un pólipo milimétrico aparentemente hiperplásico. Biopsia: NEC de alto grado. En el estudio de extensión se observa engrosamiento de la mucosa del canal anal que invade el esfínter interno, sin enfermedad a distancia. Se realiza amputación abdominoperineal laparoscópica donde se objetiva infiltración del tabique rectovaginal, por lo que se realiza resección y vaginoplastia. AP: NEC con estadio PT4B N2A, por lo que se indica quimioterapia adyuvante. Discusión: La presentación clínica de los NEC de canal anal es inespecífica, diferenciándose de otros tumores colorrectales en que hasta el 67% de los pacientes presentan metástasis al diagnóstico, siendo la supervivencia media de 11 meses. Si diagnosticamos un NEC localizado de forma incidental, es fundamental la celeridad en su tratamiento, dada su agresividad.

Introduction: Neuroendocrine carcinomas (NEC) of the anal canal are extremely rare neoplasms, representing 1 to 1.6% of all neuroendocrine tumors (NET). They are usually poorly differentiated, very aggressive and with a high tendency to metastasize. Clinical case: A 52-year-old woman diagnosed with anal fissure. During the LIS, an apparently hyperplastic millimetric polyp is evidenced. Biopsy: high-grade NEC. The imaging study shows thickening of the mucosa of the anal canal that invades the internal sphincter, without metastases. We performed a laparoscopic abdominoperineal amputation, and noticed an infiltration of the rectovaginal septum, so resection and vaginoplasty was performed. Pathology: NEC with stage PT4B N2A, for which adjuvant chemotherapy is indicated. Discussion: The clinical presentation of NEC of the anal canal is nonspecific, differing from other colorectal tumors in that up to 67% of patients have metastases at diagnosis, with a median survival of 11 months. When an incidentally localized NEC is diagnosed, prompt treatment is essential, given its aggressiveness.

Sobrevida del adenocarcinoma ductal de páncreas

El objetivo de este trabajo es analizar la presentación epidemiológica y la sobrevida de los pacientes con adenocarcinoma ductal de páncreas de acuerdo con su estadío clínico y al tipo de intervención realizada, en una cohorte de pacientes atendidos en una clínica en Lima, Perú. Estudio de cohortes retrospectivas que evaluó desde enero del 2015 a febrero del 2021 a pacientes con diagnóstico de adenocarcinoma ductal de páncreas considerando diversos factores epidemiológicos, radiológicos, estadiaje oncológico, haber recibido quimioterapia neoadyuvante o adyuvante, haber sido sometidos a cirugía y la sobrevida posterior a alguna de las intervenciones realizadas. De los 249 pacientes analizados, se encontró que 75 de ellos requerían cirugía resectiva. Entre los principales resultados obtenidos, se observó que aquellos con un nivel de CA 19-9 menor a 200 U/mL presentaban una media de sobrevida más alta en comparación con aquellos cuyo nivel de CA 19-9 era superior a 200 U/mL (HR: 1,96; IC95%: 0,18-0,53; p≤0,001). Asimismo, al comparar a los pacientes según su etapa, se encontró que aquellos con tumores resecables tenían una media de sobrevida de 37,72 meses, mientras que aquellos con tumores localmente avanzados tenían una media de sobrevida de 13,47 meses y aquellos con tumores metastásicos tenían una media de sobrevida de 7,69 meses (HR: 0,87; IC95%: 0,31-0,25; p≤0,001). Igualmente, se observó que recibir tratamiento neoadyuvante se asociaba con un mejor pronóstico de sobrevida para los pacientes (HR: 0,32; IC95%: 0,19-0,53; p≤0,001). Asimismo, se llevaron a cabo 5 pancreatectomías con resección metastásica en pacientes oligometastásicos tratados con quimioterapia de rescate, y se encontró que la media de sobrevida para estos pacientes fue de 22,51 meses. Conclusión: La cirugía resectiva en un estadío clínico temprano , presentar valores de CA 19-9 por debajo de 200 U/mL y haber recibido quimioterapia neoadyuvante se correlaciona estadísticamente con una mayor esperanza de sobrevida.

The objective of this study is to analyze the epidemiological presentation and survival of patients with pancreatic ductal adenocarcinoma according to their clinical stage and the type of intervention performed, in a cohort of patients treated at a clinic in Lima, Peru. A retrospective cohort study evaluated patients diagnosed with pancreatic ductal adenocarcinoma from January 2015 to February 2021, considering various epidemiological factors, radiological findings, oncological staging, receipt of neoadjuvant or adjuvant chemotherapy, undergoing surgery, and post-intervention survival. Out of the 249 patients analyzed, 75 of them required resective surgery. Among the main findings, it was observed that those with a CA 19-9 level below 200 U/mL had a higher median survival compared to those with a CA 19-9 level above 200 U/mL (HR: 1.96; 95% CI: 0.18-0.53; p≤0.001). Furthermore, when comparing patients according to their stage, those with resectable tumors had a median survival of 37.72 months, while those with locally advanced tumors had a median survival of 13.47 months, and those with metastatic tumors had a median survival of 7.69 months (HR: 0.87; 95% CI: 0.31-0.25; p≤0.001). Additionally, receiving neoadjuvant treatment was associated with a better prognosis of survival for patients (HR: 0.32; 95% CI: 0.19-0.53; p≤0.001). Furthermore, 5 pancreatectomies with metastatic resection were performed in oligometastatic patients treated with salvage chemotherapy, and the median survival for these patients was 22.51 months. Conclusion: Resective surgery at an early clinical stage, CA 19-9 levels below 200 U/mL, and receiving neoadjuvant chemotherapy are statistically correlated with a higher overall survival.
