Core Tip

Core Tip: From the viewpoints of overall survival and cancer-specific survival, this study investigated the survival probability based on independent prognostic indicators in gastric cancer with lung metastasis (GCLM) patients and generated a nomogram; the cumulative incidence of disease initiation was predicted. A risk score is assigned to each patient, and vital assistance is offered for individualized treatment plans in GCLM. Moreover, this groundbreaking study provides a model for the prognosis and prevention of various malignancies.
