Active clinical trials for "Stomach Neoplasms"

This prospective, single arm phase II study is designed to evaluate the rate of pathologic complete response of neoadjuvant chemoradiotherapy and neoadjuvant chemotherapy followed by surgery for locally advanced gastric adenocarcinoma

Treatment for stage 4 gastric cancer with peritoneal carcinomatosis has been unchanged for decades. The median survival for stage 4 gastric cancer is 9-14 months with systemic chemotherapy. Intraperitoneal chemotherapy in combination with systemic chemotherapy is under many clinical trials mainly in Japan, and are showing promising results. This is Korea's first clinical trial on Intraperitoneal Paclitaxel with Systemic mFOLFOX6 chemotherapy.

The aim of this study is comparing the short-term quality of life between laparoscopy-assisted distal gastrectomy and totally laparoscopic distal gastrectomy for gastric cancer.

This research is designed to compare proximal gastrectomy anterior anastomosis with pyloroplasty with esophagogastric anastomosis for gastric cancer. Gastroesophageal reflux disease, postoperative quality of life, short term outcomes, and long term outcomes will be compared.

Gastric cancer patients with stage III will be randomized to immune nutrition support or control group at discharge after total gastrectomy. Patients will receive 6 months of immune nutrition support or normal diet after discharge. The primary and secondary outcomes will be collected.

The incidence of adenocarcinomas of the esophagogastric junction (AEJ) has increased rapidly during the past decades. By the Siewert classification, the AEJ is the tumor center located 5 cm above the anatomic cardia and 5 cm below it, which is divided into three individual subtypes. Complete tumor resection is the primary therapy strategies for tumors of the AEJ. The Japan Clinical Oncology Group 9502 (JCOG 9502) found that transabdominal or transhiatal approach gastrectomy has better survival outcomes compared with left thoracoabdominal approach surgery for Siewert II/III tumors. Transabdominal approach gastrectomy is recommended as the standard treatment strategy for Siewert II/III tumors by the guidelines of the Japanese Gastric Cancer Association (JGCA). However, the length of the proximal resection margin for Siewert-II/III tumors by transabdominal/transhiatal gastrectomy is still controversies. Previous study found that longer than 2cm proximal resection margin had better survival outcome than less than 2cm proximal resection margin for Siewert-II/III tumors. On the other sides, due to more advanced tumor stage of patients in China when compared with Japan and Korea. It is necessary to conduct a randomized control study to analyze the length of resection margin in advanced adenocarcinomas of esophagogastric junction. Therefore, this study was aimed to include those Siewert II/III tumor patients in Gastrointestinal Surgery Department, West China Hospital, Sichuan University to analyze the relationship between the length of proximal resection margin and survival outcomes.

Patients with resectable adenocarcinoma of the stomach or the esophagogastric junction (II-III type by Siewert) without previous therapy will be treated with one of two chemotherapy combinations before and after surgery. One half of the patients gets 5-Fluorouracil (5-FU), Leucovorin, Oxaliplatin and Docetaxel (FLOT), the others 5-Fluorouracil (5-FU), Leucovorin, Oxaliplatin and Irinotecan (FOLFIRINOX). Main objective of the study is median overall survival.

Surgical resection of the primary tumour and treatment of the metastatic site in oligometastatic stage IV metastatic gastric adenocarcinoma enhances survival and improves quality of life with acceptable postoperative morbidity and mortality in a selected group of operable patients with only one metastatic site that does not progress under chemotherapy.

This is a single centre randomised controlled trial, comparing perioperative FLOT versus adjuvant XELOX for locally advanced gastric and esophagogastric junction cancers. Patients with operable clinical T3 or above and N1 or above gastric and esophagastric junction cancer would be recruited. Participants would be randomised to perioperative FLOT versus adjuvant XELOX with curative radical gastrectomy. Primary outcome would be 3 year Disease Free Survival. It was calculated that 110 patients would be required to demonstrate the study hypothesis.

Surgical resection is the mainstay for gastric cancer. Surgical stress response, like insulin resistance and catabolism, is inevitable and is a risk factor for postoperative outcome. To cope with this stress, the enhanced recovery protocol has been proposed and successfully implemented in clinical practice. Recently, prehabilitation have attracted increasingly attention, which is the preoperative part of enhanced recovery pathway. Prehabtilitation are bundles of evidenced elements in order to improve patient's functional capacity. Patients with gastric cancer are usually suffered from nutritional risk, anxiety and frailty. In this trial, we investigate whether multimodal prehabilitation (exercise, nutrition and psychological support) could improve patient's functional status to better tolerate surgical trauma.
