LUNG CANCER, CANCER, NSCLC
According to GLOBOCAN 2020, lung cancer, the second most common cancer for both sexes and the most common for men, ranked first in the cause of cancer mortality in 2020 [Thermal ablation has recently been considered to be an optional therapy for advanced NSCLC. Microwave ablation (MWA), radiofrequency ablation (RFA), and cryoablation are the three most commonly used ablation categories, in which MWA has lots of advantages over the other techniques, such as less “heat‑sink” effect and better convection [At present, there is no prediction model focusing on the prognosis of patients with advanced NSCLC that received MWA and chemotherapy. Two former prediction models, which targeted predicting the local progression-free survival and overall survival (OS) of NSCLC patients treated with MWA, failed to limit the stage of NSCLC and clarify whether to combine chemotherapy with MWA [In this study, we built and validated a prediction model to predict the 1-year PFS of patients with advanced NSCLC who received MWA and chemotherapy and published a nomogram and a simplified scoring system for clinical application.
