Objectives: This study aimed to evaluate the safety and efficacy of neoadjuvant chemotherapy (NACT) followed by radical surgery (RS) among patients with locally advanced cervical cancer (LACC).
Methods: Eight hundred patients with LACC received either NACT followed by RS (NACT-RS) or RS alone. The primary outcome measures assessed the efficacy and adverse effects of NACT. Secondary outcome measures compared the preoperative clinical stage to the postoperative pathologic stage in NACT-RS and RS patients, assessed intraoperative and postoperative complications, including the adverse effects of postoperative radiotherapy and radiochemotherapy, and estimated the 5-year progression-free survival and 5-year overall survival.
Results: The clinical response to NACT was 89.54%. Patients in the NACT-RS group had lower preoperative hemoglobin levels (115.20 vs 122.04 g/L, P < 0.001), a longer operative time (mean, 233.66 vs 224.37 minutes, P = 0.008), more intraoperative bleeding (750.34 vs 684.41 mL, P = 0.011), a shorter duration of catheter use (mean, 29.84 vs 32.14 days, P = 0.036), and a lower incidence of postoperative complications (7.30% vs 13.62%, P = 0.002) and postoperative radiotherapeutic and radiochemotherapeutic adverse effects (3.16% vs 4.63%, P < 0.001) compared to patients in the RS group. The 5-year progression-free survival and 5-year overall survival were 80.30% and 81.10% in the NACT-RS group and 81.00% and 78.50% in the RS group (P > 0.05). Pathological poor differentiation, nonsquamous cell carcinoma, parametrial invasion, positive pelvic lymph node, and lymphovascular invasion (P < 0.05) were independent risk factors for recurrence.
Conclusions: Neoadjuvant chemotherapy may reduce RS-associated complications and postoperative radiotherapeutic and radiochemotherapeutic adverse effects in Chinese patients with LACC.
