Long-Term Disease-Free Survival by S-1 Therapy in a Case of Gastric Cancer with Peritoneal Dissemination
Summary
The patient was a 77-year-old woman who underwent gastrectomy for gastric cancer. Since the patient had positive peritoneal washing cytology and positive peritoneal dissemination, she was started on oral S-1 therapy post-surgery for 4 weeks, followed by a 2-week rest period. During the first course of therapy, her white blood cell count decreased; therefore, the regimen was changed to a 1-week administration, followed by a 1-week rest period. No subsequent adverse events were noted. The patient has experienced no relapse in the four years she has been followed up after surgery in our outpatient clinic. We report our experience with an elderly patient for whom S-1 monotherapy was effective in the treatment of gastric cancer with peritoneal dissemination.

症例は77歳,女性。胃癌に対して胃切除術を行った。洗浄細胞診陽性および腹膜播種陽性であったため,術後4週投与2週休薬の予定でS-1内服を開始した。好中球減少を認めたため1週投与1週休薬に変更したところ,その後は副作用を認めなかった。現在術後4年を経過し,再発なく外来通院中である。腹膜播種を有する高齢者胃癌に対してS-1単独療法が有効であった1例を経験した。
