Article Title: Pemetrexed-based chemotherapy in patients with advanced, ALK-positive non-small cell lung cancer
Abstract: Background: Anaplastic lymphoma kinase (ALK)-positive non-small-cell lung cancer (NSCLC) is highly responsive to crizotinib. To determine whether ALK-positive NSCLC is also sensitive to pemetrexed, we retrospectively evaluated progression-free survival (PFS) of ALK-positive versus ALK-negative patients who had been treated with pemetrexedbasedchemotherapy for advanced NSCLC.Patients and methods: We identified 121 patients with advanced, ALK-positive NSCLC in the USA, Australia, and Italy.Forcomparison, we evaluated 266 patients with advanced, ALK-negative, epidermal growth factor receptor(EGFR)-wild-type NSCLC, including 79 with KRAS mutations and 187 with wild-type KRAS (WT/WT/WT). We determined PFS on different pemetrexed regimens. Results: Among 70 ALK-positive patients treated with a platinum/pemetrexed regimen,the median PFS (mPFS) was 7.3 months (95% confidence interval (CI) 5.5-9.5). The mPFS of 51 ALK-positive patients treated with single-agent pemetrexed or nonplatinum/pemetrexed combinations was 5.5 months (2.8-9.0).For ALK-negative patients, PFS on all pemetrexed-based regimens was similar to that of ALK-positive patients, except in the specific setting of first-line platinum/pemetrexed where the mPFS was only 4.2 and 5.4 months in KRAS and WT/WT/WT patients, respectively. However, among patients with a never/light-smoking history (0-10 pack-year smoking history) treated with first-line platinum/pemetrexed, there was no difference in PFS between ALK-positive and ALK-negative patients. Conclusions: PFS on pemetrexed or nonplatinum/pemetrexed combinations was similar in ALK-positive and ALKnegative patients. PFS on first-line platinum/pemetrexed may be prolonged in never/light-smoking patients regardless of ALK status. © The Author 2012.
