Antimetabolites, especially antifolates, play an important role in the treatment of a variety of both malignant, and non-malignant diseases, such as rheumatoid arthritis, and bacterial and parasitic infections. Recently, new antimetabolites have become an area for anticancer drug expansion. Gemcitabine has emerged as an important new agent in several tumour types, including non-small cell lung cancer, pancreatic, bladder, breast and ovarian cancers. Capecitabine is an intriguing new prodrug, offering tumour selectivity and prolonged tumour exposure to 5-FU. More potent thymidylate synthase inhibitors have also been developed; raltitrexed and pemetrexed are now commercially available for the treatment of mesothelioma, non-small cell lung cancer and other solid cancer types. This review will describe the most recent findings and their potential clinical applications.

Lung cancer represents a significant global health burden, with non-small cell lung cancer (NSCLC) being the most common subtype. The current standard of care for NSCLC has limited efficacy, highlighting the necessity for innovative treatment options. Lidocaine, traditionally recognized as a local anesthetic, has emerged as a compound with potential antitumor and anti-inflammatory capabilities.

Background: Human Lung Carcinoma (LC) is among the most diagnosed cancers across the world among those non-small cell lung cancer (NSCLC) comprises about 85%. Next Generation Sequencing based detection of mutations are now well established in molecular oncology. With the advent of modern diagnostic methods, it is now well known that there are several mutations and gene rearrangements which are associated with the development of LC.

Background A comprehensive assessment of skeletal muscle health is crucial to understanding the association between improved clinical outcomes and obesity as defined by body mass index (BMI; calculated as weight in kilograms divided by height in meters squared) in lung cancer, but limited studies have been conducted on this topic. Purpose To investigate the association between BMI-defined obesity and survival in patients with non-small cell lung cancer who underwent curative resection, with a specific focus on the status of skeletal muscle assessed at CT. Materials and Methods This retrospective study investigated Korean patients with non-small cell lung cancer who underwent curative resection between January 2008 and December 2019.

Consolidation with PD-1/PD-L1-based immune checkpoint blockade after concurrent platinum-based chemo-radiotherapy has become the new standard of care for advanced stage III unresectable non-small cell lung cancer (NSCLC) patients. In order to further improve therapy outcomes, innovative combinatorial treatment strategies aim to target additional immunosuppressive barriers in the tumor microenvironment such as the CD73/adenosine pathway. CD73 and adenosine are known as crucial endogenous regulators of lung homeostasis and inflammation, but also contribute to an immunosuppressive tumor microenvironment.
