Filter by:Background: It is shown that TS-1 as adjuvant chemotherapy after D2 resection in patients with gastric cancer can improve DFS and OS in one Japanese Trial. And TS-1 has become one of the standard therapies to these patients. But it is still unknown whether it would improve more to OS and DFS than single TS-1 after combined with oxaliplatin . This trial is designed to investigate the efficacy and safety of TS-1 plus oxaliplatin versus TS-1 single as adjuvant chemotherapy after D2 resection in patients with gastric cancer. Patients and methods: In this study , patients with histologically confirmed gastric cancer who received D2 resection and staged II or III, aged from 18 to 70 years and with Eastern Cooperative Oncology Group performance status ≤2 and adequate organ function, are randomized 1:1 to oxaliplatin 100mg/m2 on day 1 and TS-1 40~60mg twice everyday for 14 days in a 21-days cycle for total 6 cycles followed by TS-1 single with the same dose and frequency to the end of the 1st year postoperatively(SOX) , or TS-1 single 40~60mg twice everyday for 14 days in a 21-days cycle to the end of the 1st year postoperatively (TS-1). The primary end point is overall survival (OS), and secondary end point is disease free survival(DFS) and safety. Final study analysis will be conducted in the end of the 5th year after the last patient's enrollment.
The main aim of this multicentric 5-year follow-up study is to evaluate for the first time the long-term efficacy and safety (in terms of smoking-related serious diseases requiring hospitalization) of e-cigarette smoking, comparing its health effects with those of traditional cigarette smoking and mixed electronic and traditional cigarette smoking. The study will also permit to evaluate, over a 5-year follow-up, the self-reported quality of life, and the reported adverse events according to current and past smoking habit. Finally, the study will also explore the long-term adherence to e-cigarette smoking and its efficacy of e-cigarettes in reducing and/or quitting traditional cigarette smoking.
The optimal regimen for adjuvant treatment has not been established in GC yet. We plan to compare TS-1, TS-1/oxaliplatin with or without RT in D2 resected gastric cancer.
Stage 1:First line therapy Sequential therapy of S1+Docetaxel followed by S1 is superior to concomitant S1+Docetaxel in the safety and clinical efficiency. Stage 2:Second line therapy To explore the feasibility of single drug(S1) maintenance treatment for advanced gastric cancer.
This study evaluate whether treatment of Helicobacter pylori infection reduces the incidence of gastric cancer in subjects with family history of gastric cancer.
The purpose of this study is to evaluate the clinical safety and preliminary efficacy of antigen-specific cytotoxic T lymphocytes induced by dendritic cells infected by recombinant adeno-associated virus with CEA gene in the treatment of stage IV gastric cancer patients.
- Laparoscopic distal subtotal gastrectomy with lymph node dissection as minimally invasive surgery has gained popularity for the treatment of early gastric cancer in East Asian countries, even though the long-term follow-up outcome based on multicenter randomized clinical trial (RCT) is still awaited. - For the patient with locally advanced gastric cancer, several studies indicated that laparoscopic distal subtotal gastrectomy with D2 lymphadenectomy is a technically feasible and safe procedure by experienced surgeons in high-volume specialized hospitals. However, the application of it is controversial mainly due to lack of solid evidence on the oncologic efficacy. Therefore, conventional open approach is still the current standard for advanced gastric cancer. - Nowadays, the proportion of patients with locally advanced gastric cancer is estimated up to 80 per cent of all gastric cancer cases in China. Before the clinical application of laparoscopic procedure for the treatment with curative intent to advanced gastric cancer located at the middle- or lower-third of the stomach, the oncologic efficacy must be verified. - Accordingly,the comparison of intraoperative and postoperative complications between laparoscopic and open distal subtotal gastrectomy for over 65 years old patients with gastric cancer based on a randomized controlled trial is needed.
The purpose of this study is to assess the safety and efficacy of S-1 plus oxaliplatin combination chemotherapy based on the adverse events and survival period by performing a phase I/II study of this combination in patients with D2 resection of gastric cancer.
Peri-operative treatment of locally advanced gastric cancer (LAGC) has always been argued by eastern and western scholars. For patients with clinical stage of cT4b/N+M0, or cT4aN+M0, the prognosis is rather poor, and the primary lesions might not be resectable at the time of diagnosis. MAGIC study has showed that pre-and post-operative chemotherapy with 3 cycles of ECF has increased 13% on 5yOS compared with surgery alone; However, eastern studies such as ACTS GC or CLASSIC showed that TS-1 monotherapy or XELOX (oxaliplatin/capecitabine) combination given as adjuvant chemotherapy for stage II or III patients after D2 surgery could achieve the significant survival benefit. So whether perioperative or post operative therapy is more beneficial for LAGC patients lacks of data supported by prospective study. So in this prospective randomized phase III study, the investigators aim to compare the survival benefit as well as the safety for SOX (oxaliplatin/TS-1) as perioperative therapy versus SOX or XELOX as postoperative therapy after D2 dissection.
The aim of this study is to clarify safety of robot assisted distal gastrectomy with lymph node dissection in patients with stage Ia early gastric cancer.
