Linfoma primario no Hodgkin de mama / Primary Non-Hodgkin's Breast Lymphoma

Introducción: El cáncer de mama se ha convertido en un verdadero desafío a la calidad y expectativa de vida de la población mundial, con un aumento considerable en su incidencia y prevalencia. Cuba cuenta, desde 1987, con un Programa de Control de Cáncer Mamario. Objetivo: Ejemplificar el estudio de un caso con linfoma no Hodgkin primario de la mama, su cuadro clínico y los medios diagnósticos utilizados. Caso clínico: Paciente femenina de 70 años de edad, color de la piel negra, que acudió al Consultorio Médico de la Familia por presentar malestar general, molestias y aumento de volumen en la mama derecha. Se le remitió a consulta de cirugía y se le realizaron estudios complementarios. Se detectó nódulo de mediana densidad, contornos parcialmente definidos, distorsión del tejido vecino, otros nódulos de menos tamaño y densidad en el cuadrante inferior interno, calcificaciones vasculares en ambas mamas. Una biopsia corrobora linfoma no Hodgkin difuso de células grandes de alto grado. Conclusiones: El linfoma primario no Hodgkin de mama es muy raro y de difícil diagnóstico clínico porque no se dispone de signos, síntomas o criterios de imagen específicos para ello. El autoexamen de mama continúa siendo el principal método de diagnóstico del cáncer de mama y aunque el examen clínico, el ultrasonido de mama y la mamografía apoyan la presunción, es la biopsia quien solo brinda la confirmación diagnóstica precisa(AU)

Introduction: Breast cancer has become a real challenge to the quality of life and to life expectancy of the world population, with a considerable increase in its incidence and prevalence. Cuba has, since 1987, a breast cancer control program. Objective: To present a case with primary non-Hodgkin's lymphoma of the breast in a 70-year-old patient, its clinical picture and the diagnostic means used. Clinical case: 70-year-old female patient, with black skin, who came to the family medical office due to malaise, discomfort and increased volume in her right breast. She was referred to surgery and complementary studies were performed. Nodule of medium density was identified, with partially defined contours, distortion of the neighboring tissue, together with other nodules of less size and density in the lower internal quadrant, and vascular calcifications in both breasts. A biopsy confirms diffuse high-grade large-cell non-Hodgkin's lymphoma. Conclusions: Primary non-Hodgkin's lymphoma of the breast is very rare and difficult to diagnose clinically because there are no specific signs, symptoms or imaging criteria for it. Breast self-examination continues to be the main method of diagnosis for breast cancer and, although clinical examination, breast ultrasound and mammography support such diagnostic presumption, it is the biopsy that only provides the precise diagnostic confirmation(AU)

Association between Promoter Polymorphisms of TFF1, TFF2, and TFF3 and the Risk of Gastric and Diffuse Gastric Cancers in a Korean Population

Gastric cancer is one of the most common cancers in the world. The aims of this study were to evaluate the association between polymorphisms in TFF gene family, TFF1, TFF2, and TFF3 and the risk of gastric cancer (GC) and GC subgroups in a Korean population via a case-control study. The eight polymorphisms in TFF gene family were identified by sequencing and genotyped with 377 GC patients and 396 controls by using TaqMan genotyping assay. The rs184432 TT genotype of TFF1 was significantly associated with a reduced risk of GC (odds ratio, [OR) = 0.45; 95% confidence interval, [CI] = 0.25-0.82; P = 0.009), more protective against diffuse-type GC (OR = 0.20; 95% CI = 0.05-0.89; P = 0.035) than GC (OR = 0.34; 95% CI = 0.14-0.82; P = 0.017) in subjects aged < 60 yr, and correlated with lymph node metastasis negative GC and diffuse-type GC (OR = 0.44; 95% CI = 0.23-0.86; P = 0.016 and OR = 0.20; 95% CI = 0.05-0.87; P = 0.031, respectively). In addition, a decreased risk of lymph node metastasis negative GC and diffuse-type GC was observed for rs225359 TT genotype of TFF1 (OR = 0.46, 95% CI = 0.24-0.88; P = 0.020 and OR = 0.21, 95% CI = 0.05-0.88; P = 0.033, respectively). These findings suggest that the rs184432 and rs225359 polymorphisms in TFF1 have protective effects for GC and contribute to the development of GC in Korean individuals.
