The exploration of resistance mechanisms is also critical in the context of NSCLC treatment. A study identified circ_PPAPDC1A as a key player in Osimertinib resistance, revealing its upregulation in resistant tissues and its role in promoting cell proliferation and migration (ref: Tang doi.org/10.1186/s12943-024-01998-w/). Additionally, body composition metrics were found to correlate with oncologic outcomes in patients undergoing immunotherapy, with a loss of skeletal muscle mass linked to poorer overall and progression-free survival (ref: Chaunzwa doi.org/10.1001/jamaoncol.2024.1120/). These findings collectively highlight the multifaceted nature of NSCLC treatment, where both therapeutic strategies and patient-specific factors play crucial roles in determining outcomes.
