title: [A case of early gastric cancer disappeared by endoscopic polypectomy and local injection of anti-cancer agent associated with systemic immunochemotherapy].
abstract: A 78-year-old female was diagnosed as having an early gastric cancer of II a (+II c) type with probable sm invasion by gastroscopic examination. Endoscopic polypectomy was carried out due to advanced age, severe ischemic heart disease, and refusal of surgical treatment. Most of the cancerous tissue were removed endoscopically, but biopsy specimens after polypectomy showed some tumor cells leaving at the excisional site. She was treated with local injection of OK-432 endoscopically, PSK orally, Tegafur rectally, and Lentinan intravenously. After about 7 months' treatments, biopsy specimens revealed no residual cancer cells. The total doses administered up to cure for cancer were 70 KE of OK-432, 141 g of PSK, 99 g of Tegafur, and 45 mg of Lentinan. The combination therapy with massive removal of cancer tissue by endoscopy, local injection of anti-cancer agent to residual cancerous lesion and systemic immunochemotherapy will be available and recommendable for poor risk patients with early gastric cancer.
