Özet
Purpose: Small cell lung cancer (SCLC) patients unresponsive or relapsing within 90 days following frontline chemotherapy have poor prognosis and they should be treated with different chemotherapy regimens other than those used in the first-line regimen. Currently there is no globally accepted standard chemotherapeutic regimen for the treatment of these patients. This retrospective study was designed to compare CAV (Cyclophosphamide, Doxorubicin, Vincristine), weekly topotecan and weekly irinotecan regimens and to evaluate the efficacy of the three regimens in patients with chemotherapy resistant/refractory (CRR) SCLC. Methods: A total of 67 CRR-SCLC patients, who were treated with CAV, weekly topotecan and weekly irinotecan were reviewed for weekly irinotecan (27 for 60 mg/m(2) intravenously on days 1, 8 and 15 of a 28-day cycle, 24 for CAV (Cyclophosphamide 750 mg/m(2) on day 1, Doxorubicin 50 mg/m(2) on day 1 and Vincristine 1.4 mg/m(2) on day 1 every 3 weeks), 16 for weekly topotecan (4 mg/m(2) intravenously on days 1, 8 and 15 of a 28-day cycle). Results: The median follow-up time was 12.45 months, there was no difference about disease control rates (DCR) between three chemotherapy regimens (DCR; 25.9% with irinotecan, 29.2% with CAV and 31.3% with topotecan, p=0.92). Objective response rates (ORR) for irinotecan, CAV and topotecan groups were 3,7%, 8,8%, and 0%, respectively (p=0.63). Median progression free survival (PFS) and overall survival (OS) were similar according to irinotecan, CAV, and topotecan (PFS: 1.93 months, 2.30 months and 3.45 months; OS: 2.89 months, 4.79 months and 5.81 months, respectively). The adverse events were generally mild and manageable for both hematological and nonhematological toxicities in all three arms. Conclusions: Weekly irinotecan, CAV and weekly topotecan are similarly effective and safe chemotherapy protocols for the treatment of CRR-SCLC patients.
