In conclusion, age, sex, primary tumor size, N status, number of regional lymph nodes removed, tumor grade, and chemotherapy of patients were the independent prognostic factors for NSCLC patients with IPM. We constructed and internally validated a nomogram to predict 1-year, 3-year, and 5-year OS for NSCLC patients with IPM according to independent prognostic factors. After internal validation, this novel nomogram demonstrated good calibration, discrimination, clinical utility, and practical decision-making effects for the prognosis of NSCLC patients with IPM.
