Metástasis muscular de adenocarcinoma gástrico: A propósito de un caso y revisión de la literatura / Skeletal Muscle Metastasis from Gastric Adenocarcinoma: A Case Report and Review of the Literature

Resumen Los pacientes diagnosticados de adenocarcinoma gástrico pueden desarrollar metástasis hepáticas o carcinomatosis peritoneal, pero la presencia de metástasis musculares es extremadamente infrecuente, con muy pocos casos descritos. Presentamos a una paciente de 44 años con una tumoración dolorosa en miembro superior izquierdo. Fue tratada un año antes de un adenocarcinoma gástrico con cirugía y quimioterapia. Mediante pruebas de imagen y biopsia, se le diagnosticó metástasis muscular única de adenocarcinoma gástrico, siendo intervenida realizando exéresis quirúrgica.

Abstract Patients diagnosed with gastric adenocarcinoma may develop liver metastases or peritoneal carcinomatosis, but the presence of muscle metastases is extremely rare, with very few cases reported. We present a 44-year-old female patient with a painful tumor in her left upper limb. She was treated with surgery and chemotherapy for gastric adenocarcinoma a year before. By imaging tests and biopsy, she was diagnosed with a single muscle metastasis from gastric adenocarcinoma and underwent surgical exeresis.

Linfoma primario de bazo difuso de células grandes B doble hit: un subtipo de mal pronóstico / Primary splenic diffuse large B-cell lymphoma double hit: A subtype of poor prognosis

Resumen El linfoma difuso de células grandes B (LDCGB) es el tipo de linfoma más frecuente, constituyendo un 35% de todos los casos de linfoma no Hodgkin (LNH). El linfoma no-Hodgkin primario de bazo (LNHPB) presenta una incidencia menor al 1% de todos los linfomas. Los linfomas doble hit están relacionados con el reordenamiento del gen MYC asociado a otra alteración molecular. Tienden a presentarse en varones de edad avanzada y se caracterizan principalmente por su comportamiento agresivo.

Abstract Diffuse Large-cell Lymphoma B (DLCLB) is the most common type of lymphoma, constituting 35% of all cases of Non-Hodgkin's Lymphoma (NHL). Primary Splenic Non-Hodgkin Lymphoma (PS-NHL) has an incidence of less than 1% of all lymphomas. The ''double hit'' lymphomas are related to the rearrangement of the MYC gene associated with another molecular alteration. They used to appear in older men and are mainly characterised by their aggressive behaviour.

Hiperparatiroidismo primario asociado a neoplasia endocrina múltiple tipo 1 (MEN 1). Experiencia en 71 casos / Primary hyperparathyroidism associated with MEN 1: Experience in 71 cases

INTRODUCCIÓN: El hiperparatiroidismo (HPT) asociado al MEN 1 se caracteriza por ser una afectación multiglandular, no afectándose todas las glándulas en el mismo momento. Suele ser asintomático, aunque la afectación ósea es elevada en los pacientes jóvenes. Las tasa de recidiva y persistencias es de 25-35%. Los objetivos fueron: a) estudiar HPT-MEN 1; y b) analizar las variables relacionadas con la presencia o no de clínica y con la persitencia. MÉTODO: De 97 sujetos con MEN 1 diagnosticados en el HUVA, Murcia, pertenecientes a 16 familias, se han estudiado restrospectivamente 71 pacientes con afectación paratiroidea. Las variables estudiadas son: mutación, edad de diagnóstico, clínica, los valores de calcio, fóforo y PTHi, MIBI, técnica quirúrgica, valores de la PTHi y tasa de recidiva. RESULTADOS: La edad media fue de 38 años, y 50 estaban asintomáticos en el momento del diagnóstico. La técnica quirúgica realizada fue: paratiroidectomía subtotal (n = 55), paratiroidectomía de 3 glándulas (n = 7) y resección de menos de 3 glándulas (n = 9). Se asoció timectomía transcervical en 53. El seguimiento medio ha sido de 102,9 meses. Se han encontrado 21 recidivas (10 cirugía incompleta). Encontramos una relación estadísticamente significativa entre: la edad de diagnóstico (p < 0,0005) y los valores elevados de calcio (p < 0,008) y la presencia de clínica en el momento del diagnóstico, la técnica quirúrgica incompleta (p < 0,003), no timectomía (p < 0,0001) y seguimiento (p < 0,001) y la recidiva tras la cirugía. CONCLUSIÓN: La realización de screening genético y clínico nos permite un diagnóstico en fase asintomática y tratamiento precoz, evitando así complicaciones secundarias a la evolución del HPT. La tasa de recidiva del HPT en el MEN 1 es elevada, siendo los factores de recidiva el tiempo de seguimiento y la técnica quirúrgica realizada

INTRODUCTION: Primary hyperparathyroidism (pHPT) in MEN 1 is characterized by multiglandular disease and early involvement of parathyroid glands at different times. Persistence and recurrence range from 25%-35%. The purpose was: a) to describe the experience and the treatment of patients with pHPT in MEN 1; b) to analyze the variables related with clinical presentation and recurrence. METHOD: A total of 97 patients with MEN 1 were diagnosed in a tertiary hospital. A retrospective analysis was made in patients with pHPT (n = 71). Study variables: age at diagnosis, mutation, clinical presentation, laboratory tests, surgical technique, and recurrence of HPT. RESULTS: Mean age was 38 years, and 50 patients were asymptomatic. The surgical technique was: subtotal parathyroidectomy (n = 55), resection of three glands (n = 7), and resection of less glands (n = 9). Transcervical thymectomy was performed in 53 patients. Mean follow-up was 102.9 months. There were 21 recurrences, There were correlations between age at diagnosis and serum calcium levels with the presence of symptoms (P < .0001). There were also correlations between recurrence and surgical technique (P < .03), non-association with thymectomy (P < .0001), and follow-up time (P < .03). CONCLUSION: Performing genetic and clinical screening allows us to make a diagnosis in the asymptomatic period and to provide early treatment for HPT in MEN 1. The recurrence rate is high, and follow-up time and the surgical technique used are risk factors for recurrence

Factores pronósticos de los tumores neuroendocrinos de páncreas resecados. Experiencia en 95 pacientes / Prognostic factors in resected pancreatic neuroendocrine tumours: Experience in 95 patients

INTRODUCCIÓN: El objetivo de este estudio fue analizar los factores pronósticos que influyen en la supervivencia y en la recidiva en una serie de pacientes diagnosticados de tumores neuroendocrinos de páncreas (TNEP) y tratados mediante resección quirúrgica. MÉTODOS: Serie retrospectiva de 95 pacientes intervenidos y resecados de TNEP. Las variables estudiadas son: edad, sexo, forma de presentación (esporádica/familiar), funcionalidad, tipo de tumor, localización, cirugía realizada, tamaño tumoral, multifocalidad, tasa de curación y de recidiva. Se ha utilizado la nueva clasificación de la OMS en 2010. RESULTADOS: De los 95 pacientes, 45 eran varones y 50 mujeres, con una edad media de 47,6 años. Presentación esporádica en 66 pacientes (69,8%) y familiar en los 29 restantes (30,2%), asociados a síndrome MEN 1. El 59% (56 pacientes) eran no funcionantes y el 41% restante funcionantes. Los TNEP funcionantes incluían 20 insulinomas, 16 gastrinomas y 3 glucagonomas. La técnica quirúrgica más utilizada (42 pacientes) fue la pancreatectomía corporocaudal. Según la clasificación de la OMS (2010), 59 pacientes presentaban un TNEP G1, 24 un TNEP G2 y los 12 pacientes restantes un carcinoma pobremente diferenciado. La supervivencia a los 5 años en los tumores bien diferenciados ha sido del 100%, independientemente de la funcionalidad. Los TNE esporádicos suelen ser unifocales (p < 0,001) y se asocian a metástasis hepáticas. El seguimiento medio ha sido de 85,3 meses, con una tasa de supervivencia del 65,8% y de recidiva del 24%. CONCLUSIONES: En nuestra experiencia, la clasificación de la OMS (2010) es un factor pronóstico independiente en la supervivencia de los TNEP

INTRODUCTION: The aim of this study was to analyze prognostic factors for survival and recurrence in patients with resected pancreatic neuroendocrine tumors (PNT). METHODS: Medical records of 95 patients with resected PNT were retrospectively reviewed. The variables studied were: age, sex, form of presentation (sporadic/familial tumors), functionality, type of tumor, localization, type of surgery, tumor size, multifocal tumors and recurrent rate. The new WHO classification (2010) was used. RESULTS: There were 45 men and 50 women. Mean age was 46.8 years. Regarding the mode of presentation, it was sporadic in 66 patients (69.8%) and 29 cases were familial neuroendocrine tumors (30.2%) in association with MEN 1 syndrome. The 59% of patients suffered from non-functional tumors and 41% were functional: 20 insulinoma, 16 gastrinoma, and 3 glucagonoma. Distal pancreatectomy was the most common surgical procedure, followed by tumor enucleation in 19 patients. According to the WHO classification, 59 patients had a PNT G1, 24 PNT G2 and 12 with a poorly-differentiated carcinoma, respectively. The 5-year survival in well-differentiated tumors was 100%, regardless of the functionality. Sporadic PNT are more commonly unifocal (P<0.001), associating liver metastasis. Survival and recurrence rates after a mean follow-up of 85.3 months were 65.8 and 24%, respectively. CONCLUSIONS: In our experience, WHO classification was an independent prognostic factor in PNT survival
