[Therapeutic outcome and prognosis in S-1+CDDP chemotherapy for advanced gastric cancer--postoperative histopathological assessment].

Unlabelled: The efficacy and prognosis with neoadjuvant chemotherapy(NAC)for advanced gastric cancer were assessed by histopathological examination of resected tumors. The subjects consisted of cases (< or =75 y.o.

[Strategy of treatment for gastric cancer with peritoneal metastasis].

In advanced gastric cancer with peritoneal metastasis, adjuvant chemotherapy after primary tumor resection showed considerably poor prognosis with a median survival time of only 232 days. So, we changed the strategy that we start systemic chemotherapy at the earliest opportunity without resecting the primary tumor for gastric cancer patients who were diagnosed peritoneal metastasis by laparotomy or staging laparoscopy. Eleven cases of gastric cancer with peritoneal metastasis were administered systemic chemotherapy first including S-1+paclitaxel (PTX).

[A multi-centric phase I/II study of intraperitoneal docetaxel combined with S-1 for patients with peritoneal dissemination of gastric cancer].

To determine the safety profile and activity of IP docetaxel combined with S-1 for patients with peritoneal dissemination of gastric cancer, a multi-centric phase I/II study has started. Patients with histologically confirmed peritoneal dissemination by laparoscopy or laparotomy were eligible to participate in this study, but the patients with a large amount of malignant ascites were excluded. In phase I part, the patients received variable doses of intraperitoneal docetaxel on day 1 and day 15 and 80 mg/m2 of daily oral S-1 on days 1-14 every 4 weeks.

[Neoadjuvant chemotherapy using TS-1 and CDDP against large type 3/Type 4/Bulky N 2 advanced gastric cancer].

This study was conducted to assess therapeutic results following neoadjuvant chemotherapy (NAC) for large type 3/type 4/Bulky N 2 advanced gastric cancer having a poor prognosis following resection. The subjects consisted of cases (< or = 75 y.o.

[A phase I study of combination chemotherapy using TS-1 and pirarubicin (THP) for advanced gastric cancer].

The safety of chemotherapy combining TS-1 and pirarubicin (THP) for treatment of recurrent or locally advanced gastric cancer was evaluated. THP was administered by intravenous drip infusion at a dose of 14 mg/m2 every other week. TS-1 was administered orally at a dose of 40 mg/m2 twice a day for 2 weeks followed by 2 weeks of rest (level 1), for 3 weeks followed by 2 weeks of rest (level 2), and for 4 weeks followed by 2 weeks of rest (level 3).

Differential alternative splicing expressions of thymidylate synthase isoforms.

We identified two novel deletion variants of the thymidylate synthase transcript in gastric cell lines. Sequence analyses indicate that none of these variants results in introduction of a premature stop-codon or a frame shifts. In 39 gastric cancer samples, both the full-length and one-deletion variant messages were detected in cancerous as well as non-cancerous tissues.

Malignant lymphoma occurring in the residual stomach following gastrectomy: plus discussion based on the literature in Japan.

Malignant lymphoma of the remnant stomach was diagnosed in a 53-year-old man 8 years after gastrectomy for a perforated gastric ulcer. Endoscopic examination demonstrated protruding lesions spreading over the entire residual stomach, and biopsy revealed malignant lymphoma. Rectal cancer was diagnosed simultaneously.

A patient with small-cell carcinoma of the stomach with long survival after percutaneous microwave coagulating therapy (PMCT) for liver metastasis.

A 66-year-old man was admitted to our hospital with epigastralgia. Preoperative examinations revealed an 8.0 x 8.
