Lung Sarcomatoid Carcinoma
NCI Definition: A rare, aggressive, poorly differentiated, non-small cell lung carcinoma characterized by the presence of a sarcomatoid component often associated with giant cell differentiation. There is a male to female ratio of 4:1. Clinical symptoms include cough, hemoptysis, chest pain, progressive dyspnea and fever secondary to recurrent pneumonia. Cigarette smoking is a major risk factor. 
Lung sarcomatoid carcinomas most frequently harbor alterations in TP53, KRAS, CDKN2A, MET, and CDKN2B .
TP53 Mutation, TP53 c.217-c.1178 Missense, TP53 Missense, KRAS Mutation, and KRAS Exon 2 Mutation are the most common alterations in lung sarcomatoid carcinoma .
There is 1 clinical trial for lung sarcomatoid carcinoma, of which 1 is open and 0 are completed or closed. Of the trial that contains lung sarcomatoid carcinoma as an inclusion criterion, 1 is phase 2 (1 open).
Ipilimumab and nivolumab are the most common interventions in lung sarcomatoid carcinoma clinical trials.
