[A case of recurrent gastric cancer successfully treated with radiation therapy].
We report a case of recurrent gastric cancer that was effectively controlled with radiation therapy. A 63-year-old man underwent total gastrectomy, cholecystectomy and D2 dissection in February 2006 for early gastric cancer in the upper third area that was diagnosed with papillary adenocarcinoma and Stage IA (T1 (SM), N0, H0, P0, CY0, M0). He underwent lateral segmentectomy of the liver for liver metastasis of S2/3. He suffered from No. 12 lymph node(LN)metastasis in February 2009, so CPT-11, next to S-1, was administered. Portal tumor thrombosis (PTT) and liver S8 metastasis were observed in September 2009. First, chemoradiotherapy (CRT) ( S-1 80 mg/body+total of 65 Gy per 26 Fr) for #12 LN and PTT was performed and, in turn, stereotactic radiation therapy (SRT: total of 52.8 Gy per 4 Fr) was performed. A complete response in all of tumors was noted and he was presently alive with no sign of recurrence after 19 months after CRT and SRT. Grade 3 or 4 adverse events were not recognized. It is thought that radiation therapy is one of effective treatments for localized metastasis from gastric cancer.
