A 75-year-old man with type 4 advanced gastric cancer was referred to our hospital. We diagnosed the tumor as cStage III B(cT4a, cN2, cM0)gastric cancer. We selected neoadjuvant S-1 combined with CDDP therapy for him. After 2 courses of chemotherapy, the extension of the gastric wall improved. After an additional 2 courses of chemotherapy, the primary tumor revealed a partial response(PR), judged from a barium meal study and upper GI endoscopic findings, and a total gastrectomy with lymph node dissection was performed. The pathological specimens showed no cancer cells in the gastric wall and lymph nodes, so the histological effect was judged as Grade 3.

A 50-year-old man with advanced gastric cancer and a tumor embolus in the portal vein was referred to our hospital. We diagnosed the tumor as cStage III B (cT3, cN2, cH0, P0, M0) gastric cancer, and selected neoadjuvant S-1 (80 mg/m2) and CDDP (60 mg/m2) therapy for him. After 2 courses of chemotherapy, the embolus in the portal vein disappeared. After additional chemotherapy, the primary tumor and regional lymph node revealed a partial response (PR), and judging from the results from the barium meal study, upper GI endoscopic findings and CT scan, a total gastrectomy with lymph node dissection was performed.

We report the frequency of lacrimal passage disorder and the outcomes of treatment. This retrospective study was performed on 55 cases that were treated with S-1 for at least 1 month. We asked patients about ocular symptoms. An ophthalmic surgeon examined all patients and diagnosed lacrimal passage disorder in 6 of 55 patients (12. 5%). The mean dose of S- 1 was 10, 300 mg, and the average period to onset of lacrimal passage disorder was 5. 7 months. The causes of epiphora included occlusion/stenosis of lacrimal canaliculus, occlusion of lacrimal puncta and stenosis of nasolacrimal duct. Lacrimal surgery was performed in all 6 patients and epiphora improved. Lacrimal passage disorder may result from systemic treatment of patients with S-1. Symptoms of lacrimal passage disorder improved with early detection and treatment by insertion of a silicone tube.
