Filter by:We grafted the concept of metabolic surgery (long limb Roux-en Y reconstruction) into gastric cancer surgery. This study aimed to investigate the safety and efficacy of long limb Roux-en Y reconstruction after gastrectomy in non-obese type II diabetes with gastric cancer.
The study aims to: 1. Achieve molecular imaging of MG7 antigen in patients with gastric cancer in vivo using confocal laser endomicroscopy. 2. Compare the results of in vivo MG7-specific molecular imaging with CLE and ex vivo immunohistochemistry .
Although the overall incidence of gastric cancer has steadily declined in many Western countries during the last few decades, it is still one of the most common tumors in China. It is now well recognised that combination chemotherapy regimens improve patient outcomes, but there is no accepted global standard regimen for advanced gastric cancer. The ToGA study was the first randomized, prospective, multicenter, phase III trial to show the efficacy and safety of Trastuzumab in HER2- positive GC. Trastuzumab reduced the risk of death by 26% (HR 0.74; 95% CI 0∙60, 0∙91; p=0∙0046) when combined with a reference chemotherapy (Capecitabine plus Cisplatin) and prolonged the median survival by nearly 3 months (from 11.1 to 13.8 months) in patients with HER2-positive(FISH+ or IHC3+) advanced GC. Oxaliplatin has been shown to be as effective as cisplatin, and exhibits a favorable toxicity profile with a substantially lower rate of nephrotoxicity, ototoxicity, and myelosuppression. In the current study, the efficacy and safety of Trastuzumab in combination with Oxaliplatin/capecitabine chemotherapy will be evaluated in Chinese patients with HER2 positive advanced or recurrent gastric cancer.
This is a randomized multicenter controlled study of oxaliplatin, leucovorin calcium , plus 5-fluorouracil (FOLFOX) compared with S-1 plus oxaliplatin (SOX) as perioperative chemotherapy for advanced gastric cancer. Hypothesis: SOX is not inferior to FOLFOX as perioperative chemotherapy for advanced gastric cancer.
RATIONALE: Drugs used in chemotherapy, such as fluorouracil, cisplatin, and leucovorin calcium, work in different ways to stop the growth of tumor cells, either by killing the cells or by stopping them from dividing. Monoclonal antibodies, such as cetuximab, can block tumor growth in different ways. Some block the ability of tumor cells to grow and spread. Others find tumor cells and help kill them or carry tumor-killing substances to them. Giving more than one drug (combination chemotherapy) together with cetuximab before surgery may make the tumor smaller and reduce the amount of normal tissue that needs to be removed. Giving these drugs after surgery may kill any tumor cells that remain after surgery. PURPOSE: This phase II trial is studying the side effects of giving fluorouracil, cisplatin, and leucovorin calcium together with cetuximab and to see how well they work in treating patients with adenocarcinoma of the stomach or gastroesophageal junction.
Venous thromboembolism (VTE) has considerably harmful effects on morbidity and mortality of cancer patients. Several guidelines recommendations have been made about the use of anticoagulation for the prevention and treatment of VTE in Western patients with cancer. In Western VTE guidelines, all solid cancer patients receiving abdominal major surgery are strongly recommended to receive pharmacologic prophylactic anticoagulation such as low molecular weight heparin (LMWH) in the perioperative periods. These guideline recommendations are based on high incidence of postoperative VTE development in Western cancer patients. However, there have been many cumulative data about the effect of different ethnicity on the VTE development and more and more investigators and clinicians admit that Asian ethnicity has lower incidence of VTE than Western ethnicity. Therefore, it may not be advisable to apply Western guidelines as it is to the clinical situation of Asian cancer patients. Although gastric cancer is the common cancer in Asia, there is no prospective data on the incidence of VTE development during the postoperative period of gastric cancer surgery. In other words, Asian doctors including Korean clinicians don't know the exact incidence of surgery-related VTE. From their clinical experiences, most Korean surgeons think that the incidence of postoperative VTE development is rare. They also have much concern about the complications such as bleeding that might be caused by routine use of pharmacologic thromboprophylaxis during the perioperative periods. Therefore, in most clinical situation, Korean surgeons do not perform perioperative pharmacologic thromboprophylaxis using LMHW. Considering these clinical situations in Korea, the uncritical acceptance of Western guidelines is inappropriate. The necessity of pharmacologic thrombo-prophylaxis can be answered only from the results of the prospective study on the incidence of postoperative VTE development after gastric cancer surgery. Moreover, current surgical trend in cancer patients is minimally invasive approach such as laparoscopic surgery. However, the necessity of pharmacologic thromboprophylaxis in patients receiving laparoscopic cancer surgery has not been evaluated even in Western countries. Western guidelines also cannot exactly answer whether pharmacologic thromboprophylaxis is really necessary in cancer patients receiving laparoscopic cancer surgery. On above backgrounds, this study was designed.
The purpose of this study is to assess the feasibility of image-guided surgery in patients with early stage gastric cancer using Robotic Surgery with Tile-pro program. For the assessment of the feasibility, conversion to open or laparoscopic surgery due to disturbance of will indicate the failure.
Minimally invasive surgery revolutionized the field of gastric cancer surgery. The surgical robot was introduced to alleviate the difficulty of laparoscopic surgery. Although many studies have reported successful outcomes for robotic surgery, there is no multicenter prospective analysis regarding the advantage of the robotic gastrectomy. The aim of this study is to analyze the surgical outcomes of the robotic gastrectomy focusing on the learning curve, cost-effectiveness, quality of life, and acute-inflammatory reaction in comparison with laparoscopic gastrectomy.
The investigators propose to survey the frequency of HER2 (+) CTC in order to lay groundwork for future clinical trials incorporating Her-2 targeted agents in gastric cancer.
The purpose of this study is to determine maximum tolerated dose (MTD), dose limiting toxicities (DLT) and recommend a proper dose for our phase II study of S-1 when combined with radiation therapy for locally advanced or recurrent gastric cancer.
