Gynecological malignancies in Aminu Kano Teaching Hospital Kano: a 3 year review

Abstract

Objective: To study the pattern of gynecological malignancies in Aminu Kano Teaching Hospital.

Materials and methods: This was a retrospective observational study carried out in the Gynecology Department of Aminu Kano Teaching Hospital (AKTH), Kano, Nigeria between October 2008 and September 2011. Case notes of all patients seen with gynecological cancers were studied to determine the pattern, age and parity distribution.

Results: A total of 2339 women were seen during the study period, while 249 were found to have gynecological malignancy. Therefore the proportion of gynecological malignancies was 10.7%. Out of the 249 patients with gynecological malignancies, most (48.6%) had cervical cancer, followed by ovarian cancer (30.5%), endometrial cancer (11.25%) and the least was choriocarcinoma (9.24%). The mean age for cervical carcinoma patients (46.25 ± 4.99 years) was higher than that of choriocarcinoma (29 ± 14.5 years) but lower than ovarian (57 ± 4.5years) and endometrial (62.4 ± 8.3 years) cancers. However, the mean parity for cervical cancer (7.0 ± 3) was higher than those of ovarian cancer (3 ± 3), choriocarcinoma (3.5 ± 4) and endometrial cancer (4 ± 3). The mean age at menarche for women with cervical cancer (14.5 ± 0.71 years) was lower than for those with choriocarcinoma (15 ± 0 years), ovarian (15.5 ± 2.1 years) and endometrial (16 ± 0 years) cancers. There was one case of vulva cancer and none with vaginal cancer.

Conclusion: Cervical cancer was the most frequent malignant tumor and the least was choriocarcinoma. Estimates of this important public health problem need to be addressed in various regions of Nigeria.
