Case Report: A successfully managed case of SMARCA4-deficient undifferentiated gastric carcinoma
Abstract
We report a case of SMARCA4-deficient poorly-to-undifferentiated gastric carcinoma. The patient underwent surgical resection. Postoperative treatment combined chemotherapy, immunotherapy, and targeted therapy. The regimen included ifosfamide, liposomal doxorubicin hydrochloride, cadonilimab, and anlotinib capsules. Follow-up to date shows no tumor recurrence or metastasis. The postoperative relapse-free survival (RFS) has now reached 33 months. Primary gastric SMARCA4-deficient undifferentiated tumors carry a poor prognosis, with survival typically under one year. Here we present a successfully treated case of this tumor type originating in the stomach. This case may serve as a reference for future management of such tumors.
