[Debut of gastric cancer with brain metastasis: clinical surgical management]. / Debut de cáncer gástrico con metástasis cerebral: manejo clínico quirúrgico.

Gastric cancer is one of the most frequent worldwide. Brain metastases from gastric cancer are rare and are diagnosed in less than 1% of patients with gastric cancer. We present the case of a 61-year-old woman with a history of decreased visual acuity, headache, and involuntary movements. She underwent an MRI that showed a left occipital extraparenchymal appearance lesion. The PET scan reveals a hypermetabolic zone in the lesser curvature of the stomach, and the endoscopy reveals a lesion suggestive of gastric malignant neoplasia in the Borrmann I fundus. It was decided to perform a tumor excision by neurosurgery, whose pathological anatomy study revealed metastatic adenocarcinoma to the brain. She undergoes a total D2 gastrectomy, no other metastases are evident. The patient evolves favorably in the postoperative period. The pathology study revealed a poorly differentiated adenocarcinoma. In Peru and in the world, standard recommendations on how to treat these patients have not yet been established, although it is known that surgical resection of brain metastases can significantly decrease morbidity and prolong survival compared to non-surgical approaches. As far as we know, it is the first report of this type presented in the country.

Debut de cáncer gástrico con metástasis cerebral: manejo clínico quirúrgico

El cáncer gástrico es uno de los más frecuentes a nivel mundial. Las metástasis cerebrales por cáncer gástrico son poco frecuentes y se diagnostican en menos del 1% de los pacientes. Presentamos el caso de una mujer de 61 años con historia de disminución de la agudeza visual, cefalea y movimientos involuntarios. Le realizan una resonancia magnética que muestra una lesión de apariencia extraparenquimal occipital izquierda. El PET scan revela una zona hipermetabólica en curvatura menor del estómago, y la endoscopia evidencia una lesión sugerente de neoplasia maligna en fondo gástrico Borrmann I. Se decide realizar una excéresis tumoral por neurocirugía, cuyo estudio de anatomía patológica reveló adenocarcinoma metastásico a cerebro. Se le realiza una gastrectomía total D2, no se evidencian otras metástasis. La paciente evoluciona favorablemente en el postoperatorio. El estudio anatomopatológico revelo adenocarcinoma pobremente diferenciado. En Perú y en el mundo, aún no se han establecido recomendaciones estándar sobre cómo tratar a estos pacientes, aunque se sabe que la resección quirúrgica de metástasis cerebrales puede disminuir significativamente la morbilidad y prolongar la supervivencia en comparación con los enfoques no quirúrgicos. Hasta donde sabemos, es el primer reporte de este tipo que se presenta en el país.

Clinical, inflammatory and immunohistochemical features in a cohort of Peruvian patients with diffuse large B-cell lymphoma.

Data on response and survival outcomes of Latin American patients with diffuse Large B- cell lymphoma (DLBCL) are limited. We describe the clinical, inflammatory and immunohistochemical features of a cohort of DLBCL Peruvian patients treated with chemoimmunotherapy between 2010 and 2015. Logistic models were fitted for complete response (CR), and Cox proportional-hazard regression for progression-free survival (PFS) and overall survival (OS). Seventy-three patients were included in this analysis, 41 % had high/high-intermediate IPI and 48 % had high/high-intermediate NCCN-IPI scores, 41 % had non-germinal center (NGC) profile and 36 % were double expressors. CR was attained in 63 % of patients, median PFS was 53 months and median OS was 80 months. Both IPI and NCCN-IPI scores were statistically associated with PFS and OS. Neutrophil/lymphocyte ratio (NLR) ≥4 was associated with lower odds of CR (OR 0.19, p = 0.007), worse PFS (HR 2.67, p = 0.02) and worse OS (HR 2.77, p = 0.02). NLR ≥ 4 remained significant after adjusting for the IPI score and had a trend towards significance when adjusted for the NCCN-IPI score. Albumin <3.5 g/dl was associated with worse OS when adjusted for the NCCN-IPI score (HR 2.96, p = 0.04). NGC profile and double expressors were not prognostic. Our study identified NLR ≥ 4 and albumin <3.5 g/dl as potential adverse factors in DLBCL patients and could add to the prognostic value of the IPI or the NCCN-IPI scores.

Epstein-Barr virus-associated B-cell lymphoproliferative disorders and lymphomas: a review.

In this review, we focus on B-cell lymphoproliferative disorders (LPDs) and lymphomas associated with Epstein-Barr virus (EBV). In some of these diseases-such as EBV-positive diffuse large B-cell lymphoma (DLBCL), not otherwise specified-virus detection is required for the diagnosis, while in others its detection is not necessary for diagnosis. EBV infection has three main latency patterns (types III, II, and I). Different latency patterns are found in different LPD types and are related to the host immune system status. For each of the LPDs/lymphomas, we discuss the clinical presentation, epidemiology, pathology, immunophenotype, and genetic or molecular basis. We provide data for a better understanding of the relationships among the discussed diseases and other information that can be useful in differential diagnosis. Not included in this review are classic Hodgkin lymphoma and some specific variants of DLBCL, as these entities are discussed in separate reviews in this issue.

A propósito de un caso de embarazo ectópico de ovario y cuerpo lúteo roto contralateral con hemoperitoneo masivo / Ovarian ectopic pregnancy and contralateral corpus luteum rupture with masive hemoperitoneum

El presente caso reporta la existencia de un embarazo ectópico de ovario derecho que cumple los criterios de Spiegelberg para su diagnóstico asociado a la presencia de la ruptura del cuerpo lúteo contralateral con hemoperitoneo masivo, motivando una laparotomía exploradora de emergencia. El reporte anátomo patológico diagnosticó gestación en etapa inicial en ovario derecho y ruptura de cuerpo lúteo izquierdo
