A long-term survivor keeping in a complete response without treatment
after pemetrexed maintenance therapy for advanced non-squamous non-small
cell lung cancer
Molecular targeted drugs and immune checkpoint blockades are not
indicated for all advanced non-small cell lung cancer (NSCLC) cases. For
such patients, cytotoxic drugs are the main treatment, and the prognosis
remains poor. We present a valuable case of advanced NSCLC that was
potentially permanent cured by pemetrexed maintenance chemotherapy.
