Abstract
Background: Lower genital tract carcinomas that coexist with genitourinary malformations are rare. The aim of this study was to investigate the clinicopathologic characteristics and outcomes of patients with this rare joint condition. The aim of this study was to investigate the clinicopathologic characteristics and outcomes of these patients to analyze the associations among clinicopathologic features in this rare entity.
Methods: The medical records of patients with carcinoma of lower genital tract combined with genital tract malformations who were treated at Peking Union Medical College Hospital (Beijing, China) between January 1995 and December 2017 were retrospectively reviewed and a comprehensive literature review was performed. The correlations between variables were determined using Fisher's exact test.
Results: Thirty-six patients were identified, among whom 22 had cervical carcinoma, 10 had vaginal carcinoma, and two had carcinomas of both the cervix and vagina. The most common genital tract anomaly was uterus didelphys (n=17), and 63.9% of patients had with urinary tract malformations. Twenty-five (69.4%) had pathologically confirmed adenocarcinoma, 10 (27.8%) had squamous cell carcinoma (SCC), and 1 had adenosquamous carcinoma. Patients with urinary tract malformations developed adenocarcinoma more frequently than those without malformations (95.7% vs. 30.8% P<0.001). Compared with patients with SCC, patients with adenocarcinoma presented at a younger age (36.1 vs. 47.0 years, P=0.011), had more advanced stages disease (57.7% vs. 10.0% were in stage II-IV, P=0.022), and tended to have poorer five-year overall survival rates (75.6% vs. 100.0%, P=0.279).
Conclusions: Patients with simultaneous malformations of the genital and urinary tracts had a high probability of developing adenocarcinoma. It is recommended that rigorous gynecologic exams with Pap smears and imaging analyses be performed periodically in women with genital malformations, as they may be at a risk of genital malignancies.
