Validez diagnóstica de la biopsia por congelación/intraoperatoria en los tumores de ovario, mama y endometrio en pacientes tratadas en SOLCA, en el año 2015.

Abstract

The freezing biopsy is an intraoperative procedure that is used to determine a quickly histopathological diagnosis on a tumor, in this case ovary, breast and endometrium to be able to make a decision during surgery about the tumor. It has the advantage that which the result is available in minutes. The freezing biopsy defines whether the lesion is malignant or benign, defines the surgical margins of the tumor, and also determines the presence of metastasis to other tissues. Objectives: To evaluate the results of freezing biopsy in ovary, breast and endometrial tumors in SOLCA patients. Materials and methods: Patients with ovarian, breast and endometrial tumors, surgically operated and subjected to a freezing study, were studied at the Hospital Instituto Oncológico Nacional "Dr. Juan Tanca Marengo "- SOLCA, Guayaquil, during the period January to December 2015 Results: Of 764 patients with a new diagnosis of one of these cancers, only 71 patients met the inclusion criteria (n = 71). With regard to breast cancer, the age at which it occurs most is 50-59 years in 30.9%, with infiltrating ductal carcinoma being the most common. Regarding ovarian cancer, the age at which it occurs most is between 50 and 69 years, with serous papillary cystadenocarcinoma being the most common in 53.8%, whereas for endometrial cancer only the study was performed at 3 patients and it was obtained that the most common is endometrioid adenocarcinoma with 66.7%. We found a concordance of 89.1% in breast cancer, 100% in ovary and 100% in endometrium in the transoperative diagnosis with deferred. Conclusions: Freezing biopsy is a fast procedure and has a high concordance in gynecological and breast cancers, so it is very useful to guide surgery, and it is recommended to evaluate each patient to establish the benefit in each specific case.
