A retrospective study of patients with locally advanced cancer of the cervix treated with neoadjuvant chemotherapy followed by radical surgery.
New concept of downstaging locally advanced cancer of the cervix (LACC) with neoadjuvant chemotherapy (NACT), to make it resectable, is of great interest and needs to be explored. This is a retrospective study of 56 LACC patients. Efficacy of NACT was measured in terms of optimal pathological response (OR). Percentage of patients who needed adjuvant radiotherapy and disease-free interval at 2 years was evaluated. Clinically, 49 patients (87.5%) responded well to NACT with TIP regimen (paclitaxel, ifosfamide, and cisplatin) and underwent radical surgery. Adjuvant radiation was given for adverse factors in histopathology. Recurrences were noted; 46.4% of patients were in stage 2b, followed by 25% in stage IIIb; 92.8% of patients had squamous cell carcinoma. Optimal pathological response was seen in 15 patients (30.6%) with complete response in 8 patients (16.3%). Four patients (8.2%) had deposits in the parametrium, and 11 (22.4%) had positive nodes. On gross examination, 48.9% of patients had complete disappearance of cervical growth, and there was no microscopic evidence of cervical malignancy in 16.3%. In 20.4% of patients, cervical cancer was reduced to cervical intraepithelial neoplasia or microinvasion. Thirty-four patients (69.4%) needed full adjuvant radiotherapy. Overall, 14 patients (25.92%) had recurrence, with 11 (22.44%) being in NACT and radical surgery group. At 2 years, disease-free interval for 49 patients who underwent radical surgery was 69%. This study suggests that LACC patients who respond to NACT are surgically resectable with pathological cure in some cases, who are then spared from adjuvant radiation, which is given when recurrence occurs. However, with advancing stage, the percentage of OR decreases, and the need of adjuvant radiation increases.
