摘要
Background: This systemic analysis was conducted to evaluate the efficacy and safety of pemetrexed based chemotherapy in treating patients with metastatic breast cancer as first or second line chemotherapy. Methods: Clinical studies evaluating the efficacy and safety of pemetrexed based regimens on response and safety for patients with breast cancer were identified using a predefined search strategy. Pooled response rate (RR) of treatment were calculated. Results: In first line pemetrexed based regimens, 10 clinical studies which including 513 patients with advanced breast cancer were considered eligible for inclusion. For second line pemetrexed based chemotherapy, 5 clinical studies which including 281 patients with advanced breast cancer were considered eligible. Systemic analysis suggested that, in all patients, pooled RR was 32.6% (167/513) in pemetrexed based first line regimens, and 13.9 % (39/281) in pemetrexed based second line regimens. Major adverse effects were neutropenia, leukopenia, fatigue, and anemia in pemetrexed based first line treatment; and lymphopenia, neutropenia, leukopenia, as well as anemia in second line chemotherapy. One treatment related death occurred with pemetrexed based second line treatment. Conclusion: This systemic analysis suggests that pemetrexed based first line regimens are associated with a reasonable response rate and acceptable toxicity, however with low response rate for treating patients with metastatic breast cancer when is used in the second line.
