BACKGROUND Phase I/II clinical trials of S-1 plus cisplatin for advanced gastric cancer have yielded good responses and the treatment was well tolerated. In this S-1 Plus cisplatin versus S-1 In RCT In the Treatment for Stomach cancer (SPIRITS) trial, we aimed to verify that overall survival was better in patients with advanced gastric cancer treated with(More)
The efficacy and safety outcomes of laparoscopy-assisted distal gastrectomy (LADG) with D2 lymph node dissection for locally advanced gastric cancer remain unclear. Therefore, we conducted a randomized, controlled phase II trial to confirm the feasibility of LADG in terms of technical safety, and short-term surgical outcomes were investigated. Eligibility(More)
BACKGROUND The role of thymidylate synthase (TS) and dihydropyrimidine dehydrogenase (DPD) enzyme activities in tumor progression and sensitivity to 5-fluorouracil (5-FU) were evaluated. MATERIALS AND METHODS TS and DPD activities were measured in 81 clinical samples of gastric cancer. TS and DPD activities were determined by 5-fluorodeoxyuridine(More)
BACKGROUND A sensitive method for detecting minimal residual disease in the peritoneal cavity by quantifying carcinoembryonic antigen (CEA) mRNA using real-time quantitative reverse transcription-polymerase chain reaction (RQ-RT-PCR) was developed. The clinical value of the method for predicting peritoneal recurrence in patients with gastric cancer was(More)
A Phase III study was started in Japan to evaluate the non-inferiority of overall survival of laparoscopy-assisted distal gastrectomy with open distal gastrectomy in patients with clinical IA (T1N0) or IB [T1N1 or T2(MP)N0] gastric cancer. This study followed the previous Phase II study to confirm the safety of laparoscopy-assisted distal gastrectomy(More)
PURPOSE Complicated gastric lymphatic drainage potentially undermines the utility of sentinel node (SN) biopsy in patients with gastric cancer. Encouraged by several favorable single-institution reports, we conducted a multicenter, single-arm, phase II study of SN mapping that used a standardized dual tracer endoscopic injection technique. PATIENTS AND(More)
Lymph node metastasis in patients with gastric cancer is one of the important prognostic factors. However, there is no consensus concerning the best classification for lymph node metastasis as a prognostic factor. So, to evaluate the ratio of the number of metastatic lymph nodes to the total number of dissected lymph nodes (the ratio of LN meta) as a(More)
Pylorus-preserving gastrectomy (PPG) is increasingly being used to treat early gastric cancer in the middle third of the stomach, with the hope of ameliorating postoperative dysfunction and improving quality of life (QOL). We evaluated symptoms of postgastrectomy syndrome (PGS) and QOL by means of a newly developed integrated questionnaire, the(More)
BACKGROUND The Adjuvant Chemotherapy Trial of TS-1 for Colon Cancer (ACTS-CC) is a phase III trial designed to validate the non-inferiority of S-1 to UFT/leucovorin (LV) as postoperative adjuvant chemotherapy for stage III colon cancer. We report the results of a planned safety analysis. METHODS Patients aged 20-80 years with curatively resected stage III(More)
Cisplatin plus 5-fluorouracil has been globally accepted as a standard regimen for the treatment for advanced gastric cancer. However, cisplatin has several disadvantages, including renal toxicity and the need for admission. S-1 plus cisplatin has become a standard treatment for advanced gastric cancer in East Asia. This phase III study was designed to(More)
