Pemetrexed use in the adjuvant setting for completely resectable non-small-cell lung cancer.
Supported by evidence from the LACE (Lung Adjuvant Cisplatin Evaluation) metaanalysis, cisplatin-based adjuvant chemotherapy is now recommended as the standard of care for patients with surgically resected early-stage non-small-cell lung cancer (NSCLC) per American Society of Clinical Oncology and European Society for Medical Oncology clinical practice guidelines. These standard regimens, which principally include cisplatin-etoposide and cisplatin-vinorelbine, are associated with long- and short-term toxicities. Hence, cisplatin-based regimens with an improved therapeutic index and optimal safety and tolerability profile are still needed. Pemetrexed, an antifolate, is currently indicated for first-line, maintenance, and second-line therapy for advanced nonsquamous NSCLC. Pemetrexed-platinum, with or without targeted agents, has proven to be efficacious with an acceptable toxicity profile when given in the first-line metastatic setting. Therefore, it is reasonable that pemetrexed be investigated in the adjuvant setting. This review collates data from January 2000 through August 2012 on the use of pemetrexed-platinum regimens in the adjuvant setting either alone or in combination with targeted agents. To date, more than 1000 patients with early stage NSCLC have been enrolled in adjuvant therapy studies evaluating various pemetrexed-containing treatment regimens, and additional patients are being enrolled in ongoing studies. Current evidence appears to favor the combination with cisplatin over that with carboplatin. We await more robust safety and efficacy data from these ongoing adjuvant trials to define with clarity the role of pemetrexed-containing regimens in this setting.
