Survival analysis and nomogram for pulmonary sarcomatoid carcinoma: an SEER analysis and external validation.

Objective: Uncommon and particularly deadly, pulmonary sarcomatoid carcinoma (PSC) is an aggressive type of lung cancer. This research aimed to create a risk categorisation and nomogram to forecast the overall survival (OS) of patients with PSC.

Methods: To develop the model, 899 patients with PSC were taken from the Surveillance, Epidemiology, and End Results database from the USA.
