Abstract:
OBJECTIVE: This study was performed to identify the prognostic factor for survival of patients with recurrent cervical cancer. METHODS: Sixty-eight patients were diagnosed as recurrent cervical cancer at the Seoul National University Hospital from January, 1988 to December, 1998. Recurrence was defined as new evidence of tumor after 6 months of disease free survival. Retrospective analysis was done in terms of clinical features and the Cox proportional hazard model was used to identify independent variables associated with an improved survival rate. Histopathologic types were distributed as follows; squamous cell carcinoma in 70.6%, adenocarcinoma in 11.8%, adenosquamous cell carcinoma in 11.8%, and small cell carcinoma in 1.5%. Distribution of FIGO stage was as follows; stage I in 25.0%, stage II in 66.2%, and stage III in 4.4%. Sites of recurrence were as follows; central pelvic recurrence in 44.1%, pelvic side wall recurrence in 11.8%, and distant metastasis in 44.1% and the most common site of distant recurrence was extrapelvic lymph nodes (29.4%). 29.4% of recurrences were observed within the first 12 months after initial therapy, 50.0% within 2 years and 64.7% within 3 years. RESULTS: Positive rate of SCC-Ag at initial diagnosis was 45.2% with cutoff value of 2.0 ng/ml. Positive rate of SCC-Ag at the diagnosis of recurrence was 60.0%. Overall response rate to the treatment was 29.1%. Complete response rate was higher in central pelvic recurrrence than pelvic side wall recurrence and distant metastasis (P = 0.002) and also higher in normal SCC-Ag level (< or = 2.0 ng/ml) at the diagnosis of recurrence than elevated level (P = 0.032). Cumulative survival rates of 1 year after recurrence was 66.8%, 2 year 36.7%, and 5 year 18.7%. Central recurrence showed higher cumulative survival rate than pelvic side wall or distant recurrence (P = 0.029). The patients with elevated SCC-Ag level at the time of diagnosis of recurrence showed lower cumulative survival rate than those with normal SCC-Ag level (P < 0.001). Cox proportional hazard model showed that SCC-Ag elevation at the time of diagnosis of recurrence retained significant values in predicting survival(OR = 2.56; 95% CI = [1.22-5.39]; P = 0.01). CONCLUSION: SCC-Ag elevation at the diagnosis of the recurrence is a strong independent prognostic indicator for survival of patients with recurrent cervical cancer.
