Abstract

Thoracic SMARCA4‐deficient undifferentiated tumors (SMARCA4‐UT) are rare and aggressive epithelioid neoplasms characterized by the loss of the SMARCA4 gene. These tumors are typically diagnosed at advanced stages and exhibit a dismal prognosis. Currently, there are no standardized treatment protocols or approved targeted therapies.
