[A phase I study of TS-1 and weekly cisplatin in patients with advanced gastric cancer].

This is a phase I study to determine the maximum tolerated dose (MTD) and toxicity of a combination of TS-1 and weekly cisplatin (CDDP) in advanced gastric cancer patients.

Intestinal obstruction in the terminal ileum caused by an anomalous congenital vascular band between the mesoappendix and the mesentery: report of a case.

We report a case of intestinal obstruction caused by a congenital abnormal vascular band in a 17-year-old boy. The patient was admitted with acute colicky abdominal pain, and an emergency laparotomy revealed that the ileum was strangulated by a fibrous band with vessels about 2 mm in diameter and 7 cm in length, extending from the antemesenterium of the terminal ileum to the mesoappendix. The affected intestine was resected with the band and the appendix.

[A case of recurrent advanced gastric cancer with lung metastasis effectively treated by combined chemotherapy of TS-1 and weekly CDDP].

We report a case of a patient with recurrent gastric cancer and lung metastasis, who responded remarkably to combination chemotherapy using TS-1 and weekly CDDP. The patient was administered 2 courses of TS-1 (80 mg/m2/day, on day 1-21) and CDDP (25 mg/m2/day, on day 8, 15, 22) every 5 weeks. The regimen was done on an outpatient basis.
