Qin BD, et al. - Researchers established and tested a prognostic nomogram in this population cohort study by identifying the factors associated with survival in primary pulmonary salivary gland-type tumors (p-SGTs). They used 1988-2013 Surveillance, Epidemiology and End Results (SEER) database to analyze data from patients with histologically diagnosed primary p-SGTs. They used the concordance index (C-index) to assess the predictive accuracy and discriminative ability of the prognostic nomogram. By findings, pulmonary SGTs are uncommon. Factors that showed independent association with prognosis included older age, larger lesions, metastases, poor differentiation and cancer-directed surgery. These patients can experience increased overall survival if early detection and diagnosis is achieved.
