A case report of SMARCA4-deficient gastric cancer and review of the literature.
We report the case of a 50-year-old female with gastric carcinoma. The tumor was positive for epithelial and other immunological markers; however, SMARCA4 was completely inactivated. The histological and immunophenotypic findings were consistent with a diagnosis of SMARCA4-DTS. Next-generation sequencing identified a frameshift mutation in SMARCA4. The pathological diagnosis was SMARCA4-deficient gastric carcinoma. The tumor exhibits a poor response to conventional chemotherapy and has a poor prognosis; therefore, correct diagnosis is necessary. Moreover, new therapies such as EZH2 inhibitors and etoposide should be considered in cases where conventional chemotherapy is ineffective.
期刊介绍:
SAGE Open Medical Case Reports (indexed in PubMed Central) is a peer reviewed, open access journal. It aims to provide a publication home for short case reports and case series, which often do not find a place in traditional primary research journals, but provide key insights into real medical cases that are essential for physicians, and may ultimately help to improve patient outcomes. SAGE Open Medical Case Reports does not limit content due to page budgets or thematic significance. Papers are subject to rigorous peer review and are selected on the basis of whether the research is sound and deserves publication. By virtue of not restricting papers to a narrow discipline, SAGE Open Medical Case Reports facilitates the discovery of the connections between papers, whether within or between disciplines. Case reports can span the full spectrum of medicine across the health sciences in the broadest sense, including: Allergy/Immunology Anaesthesia/Pain Cardiovascular Critical Care/ Emergency Medicine Dentistry Dermatology Diabetes/Endocrinology Epidemiology/Public Health Gastroenterology/Hepatology Geriatrics/Gerontology Haematology Infectious Diseases Mental Health/Psychiatry Nephrology Neurology Nursing Obstetrics/Gynaecology Oncology Ophthalmology Orthopaedics/Rehabilitation/Occupational Therapy Otolaryngology Palliative Medicine Pathology Pharmacoeconomics/health economics Pharmacoepidemiology/Drug safety Psychopharmacology Radiology Respiratory Medicine Rheumatology/ Clinical Immunology Sports Medicine Surgery Toxicology Urology Women''s Health.
