Data about the outcome and prognostic factors in the group of patients with non-squamous cell advanced or recurrent carcinomas of the uterine cervix are limited. We compared the outcome of patients with non-squamous with that of squamous cell carcinomas after platinum-based combination chemotherapy as first line therapy for stage IV or recurrent cervical carcinoma. Patients and methods. A total of 200 patients with stage IV or recurrent carcinomas of the cervix received platinum-based combination chemotherapy and were included in our analysis. Results. There were 58 patients with non-squamous and 142 patients with squamous cell carcinomas. Response to chemotherapy was 53.5%in nonsquamous vs. 43.5%in squamous carcinomas. Histology was not an independent predictor of tumor response (P = 0.797). Response rates were lower in patients with relapse only in a previously irradiated area in both squamous (26.9%vs 53.5%, P = 0.005) and non-squamous carcinomas (47.1%vs 65%, P = 0.270). Weight loss was the only significant predictor of survival in non-squamous histology patients (P < 0.0001). There was no significant difference in median survival between squamous (11.57 months [95%CI 9.35-13.79]) and non-squa-mous carcinomas (19.05 months [95%CI 13.63-24.47]) (P = 0.064). After adjustment for independent prognostic factors (ECOG performance status and weight loss), differences in survival remained not significant. Conclusion. Our study showed a similar outcome for both squamous and non-squamous stage IV or recurrent cervical carcinomas treated with platinum-based combination chemotherapy.展开更多
