Background:
The role of intra-arterial neoadjuvant chemotherapy (NAC) in the management of cervical carcinoma has not been established. The aim of this study was to determine whether pre-operative intra-arterial NAC is effective or not in patients with stage IIb cervical carcinoma.
Patients And Methods:
A total of 28 patients with stage IIb cervical carcinoma (diameter > 4 cm) were treated with one cycle of intra-arterial NAC (cisplatin 70 mg/m2, and peplomycin sulfate 30 mg/m2 or doxorubicin 30 mg/m2) followed by radical surgery and post-operative radiotherapy. Immediate response, toxicity, survival, and prognostic factors for survival were evaluated.
Results:
The overall clinical response rate was 79% (22/28) with a complete response in 1 patient (4%). Radical hysterectomy with pelvic lymphadenectomy was feasible in 25 patients (89%) 4 weeks after chemotherapy. Toxicity were generally mild, and there were no intraoperative complications related to intra-arterial NAC. The estimated 2- and 5-year survival rates for the entire group were 93% and 80%, respectively, with a median followup time in survivors of 62 months. Univariate analysis showed the following to be significantly related to survival: histologic type, PCNA index, clinical response to intraarterial NAC, and lymph node metastasis. Survival was not significantly related to age, grade of differentiation, serum level of squamous cell carcinoma antigen, p53 protein expression, or residual parametrial involvement. Multivariate Cox's proportional hazard analysis showed that only the histologic type significantly influenced survival (p = 0.0007). The estimated 2- and 5-year survival rates were 100% and 94% for patients with squamous cell carcinoma, and 75% and 50% for those with adenocarcinoma.
Conclusions:
Intra-arterial NAC followed by surgery and radiotherapy appeared to be effective in treating patients with stage IIb cervical squamous cell carcinoma, but was not as effective in patients with stage IIb cervical adenocarcinoma.
