Thoracic SMARCA4-deficient undifferentiated tumours are ordinarily found as a huge mass with systemic metastasis, and the prognosis is poor. The potential of immunotherapy for these unresectable tumours has been reported. An asymptomatic 68-year-old man with a smoking history had a left lung mass without distant metastasis and underwent complete resection. Two months after surgery, with no adjuvant therapy, he developed multiple distant metastases with aphasia and died 4 months after surgery. Adjuvant treatment may be necessary with immune checkpoint inhibitors, with a closer follow-up to detect recurrence without symptoms.

Background: Thoracic SMARCA4-deficient undifferentiated tumors (SMARCA4-UT) exhibit a notably aggressive phenotype, which is associated with poor patient survival outcomes. These tumors are generally resistant to conventional cytotoxic chemotherapy, thereby limiting the availability of effective treatment options.
Case Presentation: We describe a 69-year-old AIDS patient who initially presented with a fused, enlarged lymph node on the right clavicle and mild, unexplained pain under the right axilla that worsened with severe coughing episodes.

Thoracic SMARCA4-deficient undifferentiated tumor (TSDUT) is a rare and quite new classification of primary pulmonary malignancy. It is classified as a non-small cell lung cancer, typically associated with smoking, and is highly aggressive. Its clinical features, immunohistochemistry, and pathology are quite unique.

Background: Thoracic tumors characterized by a deficiency in SMARCA4 are highly aggressive and linked to a poor prognosis. This retrospective study explores the efficacy and safety of immune checkpoint inhibitors (ICIs) in combination with chemotherapy for SMARCA4-deficient undifferentiated tumors (SMARCA4-dUT) and SMARCA4-deficient non-small cell lung cancer (SMARCA4-dNSCLC).
Methods: A cohort of 59 individuals was analyzed, including 35 patients with SMARCA4-dUT and 24 with SMARCA4-dNSCLC.

SMARCA4-deficient lung cancer, including thoracic SMARCA4-deficient undifferentiated tumors and SMARCA4-deficient nonsmall-cell lung carcinomas, is a rare and aggressive disease characterized by rapid progression and poor prognosis. This cancer was identified as a distinct entity with specific morphologic and molecular features in the 2021 WHO Classification of Thoracic Tumors. Molecular alterations in SMARCA4 are specific to this type of lung cancer.
