Meta-analyses showed that the response rate of TP (topotecan + cisplatin) regimen had no significant difference compared with EP regimen (etoposide + cisplatin) with OR 0.83 and 95%CI 0.63 to 1.09, but myelo-suppression such as leucopenia and thrombopenia was more severe with TP regimen; the response rate of monotherapy with topotecan was similar with that of CE (carboplatin + etoposide) regimen with OR 0.59 and 95%CI 0.22 to 1.60; the response rate of TEP (topotecan + etoposide + cisplatin) regimen was comparable with that of EP regimen with OR 1.37 and 95%CI 0.82 to –2.28, but myelosuppression and anemia were more severe with TEP regimen; the response rate with OR 0.97 and 95％CI 0.60 to –1.57, median time to progression with WMD –2.32 and 95％CI –5.72 to 1.09 and median survival time with WMD –1.65 and 95％CI –7.13 to 3.83 of IV topotecan were similar to those of oral topotecan, while neutropenia was more severe with IV topotecan.
