Filter by:Second-line chemotherapy represents an option in gastric cancer, especially for patients with adequate performance status. Two randomized phase III trials comparing 2nd-line docetaxel with best-supportive care have reported a benefit in favor of chemotherapy. Capecitabine is a fluoropyrimidine carbamate, which has a broader spectrum of antitumor activity than other fluoropyrimidines. In gastric cancer xenografts. metronomic capecitabine inhibited angiogenesis, growth of gastric cancer and improved survival with less toxicity. Given its potential low toxicity, the combination of docetaxel and metronomic capecitabine needs to be evaluated to assess efficacy and tolerability in patients with advanced gastric cancer previously treated with a fluoropyrimidine-based and platinum-based chemotherapy.
Gastroenterologists often follow up second look endoscopy after endoscopic submucosal dissection(ESD) of gastric neoplasms because they want to prevent bleeding of procedure sites. But Goto suggested in his retrospective analysis that a second-look endoscopy after endoscopic submucosal dissection for gastric epithelial neoplasm may be unnecessary. So, the investigators try to identify the hypothesis prospectively in this study.
This study will evaluate the efficacy and safety of Herceptin in patients with metastatic or advanced gastric cancer with disease progression during platinum-based or 5-fluoropyrimidine-based chemotherapy. The anticipated time on study treatment is until disease progression.
Patients with inoperable, locally advanced or recurrent and/or HER2-positive metastatic gastric or gastro-esophageal junction cancer, with no prior treatment for metastatic disease are to be recruited in the study. In the current study, the efficacy and safety of Trastuzumab in combination with Capecitabine/Docetaxel will be evaluated in Chinese patients with HER2 positive advanced or recurrent gastric cancer.60 patients could provide adequate precision rather than controlling type I&II error. Assuming the target PFS is 6.7m, 60 patients will give 90% CI of (5.5, 8.4). Considering the 5% drop out rate, 65 patients will be enrolled.
The MET oncogene encodes the receptor tyrosine kinase (RTK) for hepatocyte growth factor (HGF) and controls genetic programs leading to cell growth, invasion and protec¬tion from apoptosis. Although the definitive role of MET oncogene is yet to be determined in carcinogenesis of gastric cancer, overexpression and amplification of c-Met has been demonstrated in gastric cancer cell lines. In addition, approximately 10-20% of gastric cancer tissues and up to 40% of the scirrhous histological subtype were shown to harbor increased MET gene copy numbers. Importantly, PHA-665,752, a selective c-Met kinase inhibitor showed significant reduction of established tumor mass in mouse xenografts with GTL16, a gastric cancer cell line with >10-fold MET amplification. Another pivotal study showed that gastric cancer cells with MET amplification were extremely sensitive to PHA-665,752 and implicated a potential role of c-Met protein in developing theranostics in gastric cancer. More and more data indicated that c-Met was an important prognostic factor in gastric cancer. Gastric cancer is a heterogeneous disease. Does the expression and amplification of c-Met in the primary lesion differ from the metastatic disease? Does the expression and amplification of c-Met in the early disease differ from advanced disease? Till now there is no related report. Purposes: - Compare the expression and amplification of c-Met between primary lesion and metastatic lesion together with clinical characteristic, to explore the relationship of c-Met expression and metastatic pattern - Compare the expression and amplification of c-Met between early stage and metastatic stage, and to explore the role of c-MET in the development of carcinoma
Elderly patients are generally underrepresented in the study populations of combination chemotherapy trials. In gastric cancer patients, oxaliplatin has shown a more favorable toxicity profile than cisplatin. A combination chemotherapy of 5-fluorouracil (5-FU) with oxaliplatin, mainly FOLFOX regimens, has been investigated in numerous phase II studies, using different doses and schedules, and has shown considerable antitumor activity. Insofar as toxicity is concerned, significant toxicities, including myelo-suppression and peripheral neuropathy, are a major issue for elderly patients. A modified FOLFOX regimen by omitting the administration of bolus 5-fluorouracil have shown a good profile of activity and tolerability in the elder population. This study evaluates the efficacy and safety of a modified FOLFOX (m FOLFOX) regimen for up to 8 cycles followed by capecitabine maintenance in elderly patients with metastatic gastric cancer and presenting associated disease(s)
Title: The role of early systematic best palliative care versus on request palliative care consultation during standard oncologic treatment for patients with advanced gastric or pancreatic cancers: a randomized, controlled, multicenter trial. Description of Study Treatment: 1. Interventional arm Patients will receive standard oncologic care and will be assigned to early systematic best palliative care. They will meet a member of the palliative care team within 2 weeks after enrolment. Thereafter, they shall be visited by a palliative care team member every 2 weeks until death. Patients assigned to this experimental arm will be evaluated if the total of palliative care visits between T0 (day of enrollment) and T1 (12±3 weeks) is ≥3. Palliative care visits and intervention has to be oriented by the General guidelines for palliative care: specific attention will be paid to assessing physical and psychosocial symptoms, establishing goals of care, assisting decision making regarding treatment, and coordinating care on the basis of the individual needs of the patients. The doctor expert in palliative care, with regular visits in the experimental arm, must be a physician dedicated full time to palliative care, that can directly prescribe drugs and other interventions, and with a particular attention to physical, psychological, and spiritual needs. Palliative care doctor must have the possibility to decide about organizational arrangements. He has to perform the palliative care visit according to Temel indications. 2. Standard arm Patients will receive standard oncologic care and will be assigned to on request palliative care consultation. They will be not scheduled to meet with the palliative care service unless a meeting will be requested by the patients, the family, or the oncologist. After the time of evaluation (T1) patients will be followed by the palliative care services as needed. Patient completes QoL (Quality of Life) and mood questionnaires at baseline and at 12 weeks ± 3. Patients will receive standard antineoplastic treatment in both arms of the study according to best clinical practice in each participating centre.
The purpose of this study is to find out whether the nutritional status of patients undergoing Functional Jejunal Interposition is better than those with Roux-en-Y After Total Gastrectomy for Gastric Cancer. To find a better reconstruction for patients who received total gastrectomy.
Famitinib is a tyrosin-inhibitor agent targeting at c-Kit, VEGFR2, PDGFR, VEGFR3, Flt1 and Flt3. Phase I study has shown that the toxicity is manageable. The purpose of this study is to evaluate the efficacy and safety profile of Famitinib in patients with advanced or metastatic Gastroenteropancreatic Neuroendocrine Tumor.
The purpose of this study is to evaluate progression-free survival in participants with gastric or gastroesophageal junction cancer who have had disease progression following first-line therapy who undergo treatment with ramucirumab.
