Significant strides are being made in lung cancer care. A dynamic nomogram model was developed to predict brain metastasis risk in stage III non-small cell lung cancer patients undergoing chemoradiotherapy, facilitating early intervention measures. Neoadjuvant chemoimmunotherapy followed by surgery shows promising outcomes in stage III locally advanced NSCLC, combining therapies to improve remission rates. Additionally, AI models have been created to automate lymph node delineation and extranodal extension detection, enhancing radiotherapy precision. Together, these advances improve prognosis and treatment planning in lung cancer management.
