Objectives: To evaluate the feasibility, toxicity and activity of neoadjuvant chemotherapy (NACT) using cisplatin and topotecan in patients affected by locally advanced cervical cancer (IB2-IIIB).
Methods: Patients with histologically confirmed FIGO stage IB2-IIIB uterine cervical cancer were treated with topotecan 0.75 mg/m(2)/day (days 1-3) followed by cisplatin 75 mg/m(2) (day 1), every 21 days for three consecutive cycles. After the last cycle of chemotherapy, within 3 or 4 weeks, patients underwent radical surgery with lymph node dissection.
Results: In the years 2007-2010, 46 women were enrolled into the study. Hematologic toxicity was the most relevant side effect. Thirty-eight patients (82.6%) underwent radical surgery after neoadjuvant chemotherapy (NACT) and were assessable for pathologic responses; surgery was not performed in 8 (17.4%) non-responder patients or with progression disease. Objective pathological response was recorded in 34 patients (89.5%); 6 patients (15.8%) achieved a complete response (CR), 28 (73.7%) patients achieved a partial response (PR); stable disease (SD) occurred in 2 patients (5.3%) with IIA initial disease and progression disease (PD) was registered in 2 patients (5.3%) with IIIB initial disease. The cumulative 2-year progression free survival (PFS) and overall survival (OS) of the 46 enrolled patients in the study were 70% and 81%, respectively; the 2-year PFS and OS of the 38 operated patients were respectively 79% and 95%.
Conclusions: The cisplatin-topotecan combination seems to be feasible and with an acceptable toxicity profile and a promising response rate for the treatment of locally advanced cervical cancer (LACC). Phase II and III studies are needed to compare this combination with other platinum-based chemotherapeutic associations.
