Abstract

The aim of this study was to summarize the clinical and pathological characteristics and to conduct prognosis analysis of patients who were diagnosed with clear cell carcinoma of the uterine cervix (CCCUC) and without a history of exposure to diethylstilbestrol. We performed a retrospective review of all the patients with CCCUC who were diagnosed and treated at Zhejiang Cancer Hospital between 1998 and 2014. Charts were reviewed for clinical and pathological characteristics, and prognosis analysis was conducted. A total of 47 patients were included. Median age was 52 years. No patient had a history of exposure to diethylstilbestrol. The International Federation of Gynecology and Obstetrics stage distribution was 55.3% (n = 26) stage I, 40.4% (n = 19) stage II, 2.1% (n = 1) stage III, and 2.1% (n = 1) stage IV. Forty-two patients (89.4%) underwent radical hysterectomy and pelvic lymphadenectomy. Pathological examination revealed deep cervical stromal invasion (greater than two thirds) in 20 patients (48.4%), pelvic lymph node (PLN) metastasis in 10 patients (23.8%), lymphovascular space involvement in 9 patients (21.4%), and ovarian metastasis in 1 patient (2.4%). Advanced tumor stage (IIB-IV), larger tumor size (>4 cm), and PLN...Continue Reading
