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

Methods： Fifty-one patients with cSLC and 281 with ncSLC confirmed by surgery in our hospital between 1999 to 2000 were collected and their clinical, histological and survival features were retrospectively ana（yzed. Results： Patients with cSLC had more frequent manifestation of infection and weight loss. They usually experienced longer duration of pre-diagnosis and showed bigger tumor mass, larger primary tumor invasion with worse differentiated than ncSLC patients. There was no significant difference in age, sex, smoking history, family tumor history, personal tuberculosis history, disease location, TNM stage, lymph node invasion, and metastasis between the two groups. Median survival time was 29 months for cSLC and 35 months for ncSLC. One- and 3- year survival rates were 86.3% and 43.1% for cSLC vs. 91.1% and 47,0% for ncSLC respectively （P〉0.05）. Conclusion： Patients with cSLC presented with a bigger mass, a larger extent of primary tumor invasion, worse differentiated, more obstructed pneumonia that might result in longer duration of pre-diagnosis and more weight loss. As lack of differences in disease stages, lymph node invasion, metastasis and especially survival time with ncSLC, cSLC couldn＇t be classified as a special type of squamous cell carcinoma by present evidences.展开更多
