ABSTRACT

Las metástasis de carcinomas extragenitales al útero es rara y el compromiso al cuello uterino es excepcional, especialmente del tipo histológico de carcinoma de células en anillo de sello. Se presentan tres casos encontrados en 240 adenocarcinomas cervicales (1,25 por ciento) diagnosticados entre 1979-2012. Dos casos se presentaron en pacientes de 48 y 56 años originados en carcinomas lobulillares infiltrantes de la mama diagnosticados previamente. La primera paciente está viva a 19 meses del diagnóstico ginecológico y la segunda falleció a los 14 meses, siendo en ambas un hallazgo histológico incidental en cirugías realizadas por patología ginecológica benigna. El tercer caso se presentó en una paciente de 43 años que debutó por metrorragia y tumor cervical y fue originado en un carcinoma gástrico infiltrante difuso, encontrado en forma sincrónica y fallece a los 2 meses del diagnóstico. Se revisan los criterios diagnósticos entre metástasis y carcinoma primario de células en anillo de sello del cuello uterino y el aporte al diagnóstico de la histología convencional, la inmunohistoquímica y la tipificación molecular de HPV. Conclusión: Se concluye que la metástasis de carcinoma de células en anillo al cuello uterino es rara y el pronóstico es malo. La citoreducción y la quimioterapia podría tener un rol para casos seleccionados de carcinomas metastásicos de origen mamario y que estos casos no deberían ser considerados un evento preterminal.


The uterine metastatic involving of extragenital carcinomas is rare, especially the signetring cell type. Three of such a cases were found in 240 cases of adenocarcinomas of uterine cervix (1.25 percent) diagnosed between 1979-2012. Two of these cases occurred in patients aged 48 and 56 years with infiltrating lobular carcinomas arising in the breast previously diagnosed. The first patient is alive at 19 months after diagnosis and the second is deceased at 14 months after diagnosis. In both cases, the metastasis to the cervix was an incidental histological finding in surgeries performed by benign gynecological pathology. The third case was identified in a 43-years old patient who debuted with metrorrhagia and cervical tumor which was originated in a diffuse infiltrating gastric carcinoma that was found synchronously and she is dead at 2 months after diagnosis. The diagnostic criteria between metastases and primary cervix carcinoma of signet ring cells and the contribution to the diagnosis of conventional histology, immunohistochemistry and molecular typing of HPV are reviewed. The metastasis of signet ring cell carcinoma to the uterine cervix is rare and the survival is poor. Conclusion: The role of cytoreduction and chemotherapy for selected cases of metastasis from breast carcinomas should be considered and in such a case the gynecological involvement should not be considered a preterminal event.

ABSTRACT

Objetivo: Analizar los resultados de la escisión de la zona de transformación del cérvix efectuadas en la Unidad de Patología Cervical del Hospital Guillermo Grant de Concepción. Método: Estudio descriptivo, retrospectivo, de los antecedentes clínicos e histológicos de 1.141 casos de escisión electro quirúrgica efectuados entre 1999 a 2005, con seguimiento mínimo de 18 meses. Resultados: De las 3.004 mujeres derivadas por citología positiva para neoplasia y/o HPV, a 1.141 (37,9%) se les realizó escisión de la zona de transformación; 1.113 con asa electroquirúrgica (97,5%) y 28 (2,5%) cono frío con bisturí. Las lesiones intraepiteliales (LIE) de alto grado fueron las más frecuentes (66,7%), seguidas por las LIE de bajo grado (7,8%); el 6,5% de las pacientes presentan etapas iniciales de carcinoma invasor; 33% de las piezas histológicaspresentaron bordes comprometidos; 18,4% no presentaron lesión histológica, que sumadas a 7,8% de LIE de bajo grado representan un 26,2% de mujeres consideradas como sobretratadas. El porcentaje a 18 meses de seguimiento en mujeres con LIE de alto grado fue de 85,5%. Necesitaron de una segunda intervención 194 pacientes (17%), 110 (9,6%) por persistencia y recidivas de la lesión. Conclusión: Los resultados presentados son satisfactorios en el porcentaje de curación de las LIE de alto grado como en el aporte al diagnóstico precoz de carcinomas del cérvix y similares a estudios publicados tanto nacionales como extranjeros.


Objective: To analyze the results of 1,141 cervical excisions. Method: Descriptive and retrospective study of the clinical charts and biopsies of 1,141 cases with surgical resection of the uterine cervix performed from 1999 to 2005. Only patients with a minimum of 18 months of follow up were included. Results: From 3,004 patients with a positive Papanicolaou smear for neoplastic cells and/or condyloma, 1,113 (97.5%) were treated with loop electrosurgical excisional procedure (LEEP) and 28 (2.5%) with cold-knife conization. The most frequent lesion (66.7%) found was high grade squamous intraepithelial lesions (SIL), follow by low grade SIL (7.8%); 74 patients (6.5%) presented with early stage of squamous cell carcinoma and 377 (33%) of the histological specimens revealed positive margins; 210 (18.4%) of the cases showed no histological lesion. There were a 26.2% of females that were considered to receive over treatment. After 18 months follow up 85.5% of patient were free of high grade SIL. A second surgical treatment was done in 194 patients (17%) including 110 cases (9.6%) with persistent or recurrence of the lesion. Conclusions: The results are satisfactory related to treatment of high grade SIL and it contributes to the early diagnosis of cervical cancer. The results are similar to other national and international series previously published.
