Purpose of investigation: In Iran, the authors use neoadjuvant chemotherapy (NACT) prior to surgery in cervical cancer due to limited access to the radiotherapy and very prolonged waiting time in accession to radiotherapy. The study was done to analyze the efficacy of the NACT with high dose-dense paclitaxel and cisplatin before radical surgery on cure rate, survival rate, and the progression of free survival rate of bulky tumor of cervical cancer in Stages IB2, IId A2, and IIB. Materials and Methods: Fiftytwo patients with cervical cancer in Stages Ib2, IIA2, and IIB were selected, and responding patients to chemotherapy were scheduled to undergo radical hysterectomy and bilateral pelvic lymphadenectomy with or without para-aortic lymphadenectomy. Results: Fifty out of 52 patients with a median age of 50 years were evaluable for clinical response. Thirty-two patients (64%) responded to the NACT including six (12%) with a complete clinical response. There was no statistical relationship between clinical response, tumor stage and size, and parametrical involvement, however, patients with higher grade of tumor, adenocarcinoma or tumor in upper 2/3 of vagina showed a higher probability of no response to chemotherapy. Downstaging after NACT in all stages was statistically significant regarding pathologic findings and clinical response (p = 0.002). Five-year survival was 88% and factors affecting survival and disease-free survival were pathological response and tumor site based on cox-regression analysis. Overall recurrence rate was 20% and tumor size was the only significant relevant factor for recurrence (p = 0.017). Conclusion: Combined regimen of chemotherapy in locally advanced cervical cancer proved to be valuable and efficacious without any late complications.
