Intrathecal pemetrexed efficacy and cerebrospinal fluid tumor marker response in refractory leptomeningeal metastasis of non-small-cell lung cancer: a single-arm phase II trial

Abstract Background The treatments for refractory leptomeningeal metastasis (RLM) of non-small cell lung cancer (NSCLC) are limited, and response assessment is complex and challenging. This clinical trial aimed to evaluate the efficacy of intrathecal pemetrexed (IP) and response assessment using cer...
