Active clinical trials for "Stomach Neoplasms"

Surgical quality control is a crucial determinant of evaluating the tumor efficacy. We assess the ClassIntra grade for quality control and oncological outcomes of robotic radical surgery for gastric cancer (GC).

A retrospective, multi-center, single-blind, pivotal trial to assess clinical equivalence with stage II and III advanced gastric cancer based on the 6th and 8th of the AJCC

More than 20% of patients with gastric cancer have at presentation a stage IV disease. Advanced adenocarcinoma of the antro-pyloric region often determines a condition of gastric outlet obstruction syndrome (GOOS), which requires a rapid resolution for the severe consequences that will occur if the obstruction is not resolved. GOOS causes malnutrition, fluid and electrolyte imbalances that are difficult to control. Laparoscopic or open gastroenterostomy has been proposed as the treatment of choice in patients with advanced unresectable distal stomach tumor presenting with symptoms of GOOS. Noticeably, laparoscopic gastroenterostomy might be difficult to be performed in a hostile abdomen because of the involvement of the root of the mesentery, infiltration of the surrounding structures and peritoneal carcinosis. Furthermore, laparoscopic or open gastroenterostomy provides suboptimal palliation, because it is associated with postoperative complications ranging from 15% to 50% related to a delayed gastric emptying and a protract postoperative hospital stay. These results negatively affect the quality of life (QoL), and therefore, the efficacy of gastroenterostomy for palliation has been questioned. In 1997, Kaminishi et al. introduced a technique of stomach-partitioning gastrojejunostomy (SPGJ), which divides the lower part of the stomach and connects the jejunum to the proximal part of the stomach while maintaining a tunnel that is 2 to 3 cm in diameter along the lesser curvature. This technique theoretically provides some benefits: endoscopic evaluation of the tumor response to adjuvant chemotherapy and the possibility of repeated endoscopic local treatment on the tumor, prevention of ingested food retention in the distal part of the stomach thus facilitating gastric emptying and improving patient's QoL. A current alternative to laparoscopic or open surgical approach to an advanced gastric tumor is the positioning of a self-expandable metal stent (SEMS) which offers many potential advantages: the avoidance of general anaesthesia for a laparoscopic or open approach, a shorter hospital stay and a minor patient postoperative discomfort. We want to perform a prospective longitudinal cohort trial, comparing the QoL of patients affected with stage IV antropyloric stomach cancer and symptoms of GOOS who underwent endoscopic placement of a SEMS or after open SPGJ.

The study was designed to evaluate the effectiveness of the maximum dose of mucolytic solution used before upper endoscopy on the visibility of the gastric mucosa

Gastric cancer (GC) is more prevalent in males than in females. One of these differences could be the effect of sex hormones such as estrogens. However, few reports have been reported regarding sex and age differences of incidence and survival of GC. The aim of this study was to evaluate the effect of sex and age on the incidence and survival of GC. And we would like to further analyze single GC and synchronous multiple GC, EBV, etc.

This study investigates the safety and feasibility of performing laparoscopic surgery for colorectal and gastric cancer inside versus outside the primary registered medical institution under multi-sites practice (MSP) policy. This is a single practitioner, retrospective comparative study. The endpoints are peri-operative outcomes, pathological results, and medical costs.

Surgery is the mainstay treatment of operable gastric carcinoma but the optimal extent of lymph node (LN) dissection is controversial. The aim of this observational study is to assess the outcomes after curative D2 compared to D1 gastrectomy of operable gastric carcinoma regarding operative and long term oncological outcomes.

This study aims to explore the value of 68Ga-FAPI PET/CT in the diagnosis of gastric cancer peritoneal carcinomatosis in high-risk patients compared with conventional abdominal enhanced CT and 18F-FDG PET/CT. The patients with gastric adenocarcinoma (cT4/N+/M0-1) will be studied.

Recently, cytokine polymorphisms are considered to play an important role in the pathogenesis of peptic ulcer and gastric cancer. We intended to clarify the association between polymorphisms of pro-inflammatory and anti-inflammatory cytokines, and the susceptibility to gastric cancer, gastric ulcer and duodenal ulcer in Japan, and to detect the individuals who have higher risks for gastrointestinal disease development.

The median survival at progression after first-line chemotherapy for metastatic gastric cancer is about 2.5 months. There are no data which a possible benefit of second line therapy. for this reason a trial which investigates a possible benefit or chemotherapy compared to best supportive care as second line treatment is urgently necessary. Irinotecan shows response rates of 20% in the first line therapy with high rates od disease stabilization. There are few trials investigating irinotecan in the second line setting. Response rates of 20% are reported in tis setting. Irinotecan is supplied without costs from the company Pfizer.
