RESUMEN
Antecedentes El cáncer de vesícula biliar se caracteriza por ser un tumor de mal pronóstico y diagnóstico tardío.

Objetivo:

Describir variables epidemiológicas del cáncer de vesícula en nuestro centro y compararlos con la bibliografía internacional. Material y

métodos:

En pacientes sometidos a colecistectomía entre el 1º de enero de 2006 y el 31 de diciembre de 2015, se estudiaron las siguientes variables sexo, edad, relación mujer/varón, causa de colecistectomía, clasificación en urgencias y programadas; en los casos de cáncer de vesícula sexo, edad, histopatología, diferenciación celular, invasión (de pared vesicular, angiolinfática, del ganglio cístico, tejidos vecinos y del hígado), estadificación (clasificaciones de Nevin y de Unión Internacional Contra el Cáncer-UICC).

Resultados:

Se diagnosticaron 92 neoplasias vesiculares (1,26% de todas las colecistectomías). El promedio de edad para cáncer de vesícula fue 57,9 años (rango 22-88); sexo femenino 64 (69,5%, con relación mujer/varón 21. La histopatología mostró 86 (93,4%) adenocarcinomas, 4 (4,4%) carcinomas escamosos y 2 (2,2%) indiferenciados con elementos de origen mesenquimático y epitelial de vesícula. Las lesiones asociadas fueron adenocarcinoma con metaplasia escamosa, 2 casos; mucosecretante, 2 casos; papilar, 1 caso; metaplasia intestinal y antral, 1 caso. En 60 (65,4%) casos fueron moderadamente diferenciados; bien diferenciados, 12 (13%); pobremente diferenciados, 11 (11,9%) e indiferenciados, 4 (4,3%). En 5 casos (5,4%), no se especificaba la diferenciación celular.

Conclusión:

El cáncer de vesícula diagnosticado luego de una colecistectomía es más frecuente en mujeres, con tipo histológico adenocarcinoma, llamando la atención la cantidad de pacientes jóvenes diagnosticados.
ABSTRACT

Background:

Gallbladder cancer is characterized by poor prognosis and late diagnosis.

Objective:

The aim of our study is to describe the epidemiological variables of gallbladder cancer at our centre and to compare them with data from the worldwide literature. Material and

methods:

Patients undergoing cholecystectomy between January 1, 2006, and December 31, 2015. The following variables were analyzed sex, age, male to female ratio, reason for cholecystectomy, urgent or scheduled. In case of gallbladder cancer, sex, age, histopathology, cell differentiation, gallbladder layer invasion, lymphovascular, cystic lymph node, adjacent tissues and liver invasion; and cancer staging according to Nevin staging system and the Union for International Cancer Control (UICC).

Results:

Ninety-two gallbladder neoplasms were found, representing 1.26% of all cholecystectomies. Mean age of patients with gallbladder cancer was 57.9 years (range, 22-88 years) of whom 69.5% (n=64) were women, with the same female to men ratio of 21 described for cholecystectomy. The histopathology of the 92 gallbladder cancers corresponded to adenocarcinoma, 93.4% (n= 86); squamous cell carcinoma, 4.4% (n= 4); and undifferentiated malignancy with elements of epithelial and mesenchymal origin, 2.2% (n= 2). There were two cases of adenocarcinoma with squamous metaplasia, two mucinous carcinomas, one papillary adenocarcinoma and one case of antral-type and intestinal metaplasia. Sixty tumors (65.4%) were moderately differentiated; 12 (13%) well differentiated; 11 (11.9%) poorly differentiated; and 4 (4.3%) were undifferentiated. In 5 cases (5.4%) the type of differentiation was not described.

Conclusion:

In gallbladder cancer diagnosed after a cholecystectomy, it is more frequent in the female sex, with adenocarcinoma being the most common histological type. Interestingly, the number of young patients with gallbladder cancer is noteworthy.
