The aim of this study is to analysis of survival and recurrence rates of the uterine cervical carcinoma patients whom received the radiation therapy respectively. The prognostic factors, such as Papanicolaou (Pap) smear, carcinoembriogenic antigen (CEA) and squamous cell carcinoma (SCC) antigen has been studied. METHODS AND MATERIALS: From January 1981 to December 1998, eight-hundred twenty-seven uterine cervical cancer patients were treated with radiation therapy. All of the patients were divided into two groups : the radiation therapy only (521 patients) group and the postoperative radiation therapy (326 patients) group. The age, treatment modality, clinical stage, histopathology, recurrence, follow-up Pap smears, CEA and SCC antigen were used as parameters for the evaluation. The prognostic factors such as survival and recurrence rates were performed with the Kaplan-Meier method and the Cox hazard model, respectively. Median follow-up was 38.6 months.
On the radiation therapy only group, 314 patients (60%) achieved complete response (CR), 47 patients (9%) showed local recurrence (LR), 78 patients (15%) developed distant metastasis (DM). On the postoperative radiation therapy group, showed 276 patients (85%) CR, 8 patients (2%) LR, 37 patients (11%) DM. The 5-year survival and recurrence rates was evaluated for all parameters. The statistically significant factors for the survival rate in univariate analysis were clinical stage (p=0.0001), treatment modality ( p=0.0010), recurrence ( p=0.0001), Pap smear ( p=0.0329), CEA ( p=0.0001) and SCC antigen ( p= 0.0001).
This study indicated that after treatment, the follow-up studies of Pap smear, CEA and SCC antigen were significant parameter and prediction factors for the survival and recurrence of the uterine cervical carcinoma.
