Vulvar cancer in Iran: Retrospective study over 20 years (1998-2018)

Abstract

Background:

We did not have any data about vulvar cancer — as a fourth cause of gynecological cancer in the worldwide — in our country.

Study Design:

Our study is designed to evaluate the frequency, stage and outcome of patients with vulvar cancer.

Materials and Methods:

In this retrospective observational study, we studied patients’ records with diagnosis of vulvar cancer who referred to department of gynecology oncology, Emam-Khomeini Hospital (EKH), Tehran, Iran, between January 1998 and December 2018. A total of 106 cases of vulvar cancers were found in the records of outpatient oncology clinic of medical university of Tehran university. Survival was estimated using the Kaplan-Meier analysis with SPSS version of 24.

Results:

Mean age of the 106 patients in the study was 59.2 years. The most site of tumor involvement was major labial (39.1%). Vulvar cancer significantly was more in multiparous ( P < 0.001) and menopause patients ( P < 0.001). Squamous Cell Carcinoma was the most pathology of vulvar cancer (72.2%). Ninety patients (84.9%) had surgery as a primary treatment and 48 (53.3%) of these patients received adjuvant radiotherapy or chemoradiation after surgery. Mean duration of patient's follow up was 82.4 ± 68.3 month. Five-year survival of our patients in all stages was 71%.

Conclusions:

Our findings are located between developed and underdeveloped countries. Our patients are diagnosed nearly in earlier stages of disease and 84.9%t of them had surgery as a primary treatment, so earlier surgery resulted in good survival of patients.
