Objective:

The objective of the study was to show the relative frequency of gynecological cancers at an oncology unit comparing these results with two previous studies, by highlighting the increase in the number of uterine cancers.

Materials and methods:

Review the number of cases of gynecological cancers at the Oncology Service of the General Hospital of Mexico from 2016 to 2017, comparing it with two previous periods, 1983-1984 and 2010-2011.

Results:

We included 931 patients with gynecological cancers, 427 patients with cervical cancer (45.8%), 274 patients with uterine cancer (29.4%), and 206 patients with ovarian cancer (22.1%). When comparing these results with the previous ones, we found that the numbers of cervical cancer decreased from 86.8% to 57.8% to 45.8 % (p < 0.05); uterine cancer from 4.5% to 17.9% to 29.4% (p = 0.0001); and ovarian cancer from 6.2% (p < 0.05) to 19.7% (p = 0.185). The larger histological group for cervical cancer is adenocarcinomas (18.1%) and the main histology in uterine cancers is endometrial (86.8%). From this total, 71.4% patients are either overweight or obese. About 63.9% of cases were diagnosed as late-stage cancers.

Conclusions:

In this series, we detected a decrease in the frequency of cervical cancers, with adenocarcinomas increasing in percentage, and a significant increase in uterine cancers associated with overweightness and obesity. Advanced stages of gynecological cancers were prevalent.
