Our purpose was to determine the long-term prognosis in patients with stage IIIb-IVa squamous cell carcinoma of the cervix who were treated with intra-arterial neoadjuvant chemotherapy (NAC), and to analyze factors related to prognostic value. We assessed the disease-free survival of 21 patients with FIGO stage IIIb-IVa squamous cell carcinoma of the cervix treated with intra-arterial NAC (cisplatin 70 mg/m2 and peplomycin sulfate 30 mg/m2) followed by irradiation therapy. Before chemotherapy, five factors (age, clinical stage, histologic type, parametrial involvement and serum level of SCC) were evaluated for their correlation with disease-free survival. The absolute 5-year disease-free survival rate for the entire group was 52%, with a median follow-up time in disease-free survivors of 87 months. Among the prognostic factors, age was the only one to be significantly correlated with disease-free survival; older (> 60 years) patients showed a significantly better disease-free survival rate than did younger (< 60 years) patients (p < 0.05, log-rank test). The absolute 5-year disease-free survival rate was 69% for older patients and 25% for younger patients. Univariate Cox's proportional hazard model also demonstrated that age was a significant prognostic factor as a continuous variable (p < 0.01). Intra-arterial NAC thus appeared to be effective in treating older patients with stage IIIb-IVa squamous cell carcinoma of the cervix.
