Treatment of stage IIIb/IV non-small cell lung cancer with Pemetrexed plus Oxaliplatin after failure of Erlotinib as second-line treatment

To determine the efficacy and toxicity of Pemetrexed plus Oxaliplatin in patients suffering from stage IIIb or IV lung adenocarcinoma and being treated with Erlotinib as second-line treatment, a total of 45 patients were randomly divided into two groups. One group was treated with 500 mg/m(2) Pemetr...

Sumario:To determine the efficacy and toxicity of Pemetrexed plus Oxaliplatin in patients suffering from stage IIIb or IV lung adenocarcinoma and being treated with Erlotinib as second-line treatment, a total of 45 patients were randomly divided into two groups. One group was treated with 500 mg/m(2) Pemetrexed plus 100 mg/m(2) Oxaliplatin, and the other was treated with 500 mg/m(2) Pemetrexed plus 75 mg/m(2) Cisplatin. All drugs were administered on day one of a 21-day cycle. In the Oxaliplatin group, 3 patients (13.6 %) experienced partial response (PR), 9 patients (41.0 %) showed stable disease (SD), and 10 patients (45.5 %) had progressive disease (PD). In the Cisplatin group, 2 patients (8.7 %) experienced PR, 7 patients (30.4 %) showed SD, and 14 patients (60.9 %) had PD. The PFS of the Oxaliplatin group and the Cisplatin group was 4.45 months (95 % CI 4.10–4.80) and 3.96 months (95 % CI 3.68–4.24) (P = 0.03), respectively. The median overall survival (OS) was 10.8 months (95 % CI 10.2–11.5) and 10.7 months (95 % CI 10.2–11.3) (P = 0.72), respectively. There was no statistically significant difference in the occurrence rate of grades 3 and 4 myelotoxicity between the two groups. However, there was a significant difference in the occurrence rate of grades 3 and 4 gastrointestinal reactions and peripheral neurotoxicity between the two groups (P < 0.05). A regime combining Pemetrexed and Oxaliplatin was marginally effective and well tolerated in patients with stage IIIb or IV lung adenocarcinoma who have received Erlotinib as second-line treatment.
