[A Patient Who Underwent Surgery after CR to Chemotherapy for Scirrhous Gastric Cancer Suspected because of Lymphangitis Carcinomatosa].

A 58-year-old woman was diagnosed with scirrhous gastric cancer suspected because of lymphangitis carcinomatosa. She was treated with 10 courses of S-1+CDDP chemotherapy. After 3 years and 6 months, CR was obtained and she underwent curative total gastrectomy with D2 lymph node dissection plus resection of the spleen and transverse colon. The pathological results of the resected specimen were tub2>por, pT1a, N1 (No.7), M0, CY0, P0, and HER2 (3+). After surgical treatment, supraclavicular lymph node metastasis occurred, and the patient underwent trastuzumab+capecitabine therapy, which resulted in CR for 1 year and 6 months. Thus, for unresectable scirrhous gastric cancer, multidisciplinary therapy such as longterm chemotherapy including trastuzumab and surgery is useful.
