Filter by:This phase II trial aimed to assess the efficacy and safety of pemetrexed in patients with pretreated metastatic gastric cancer.
Background: - Malignant mesothelioma is a malignancy arising from the mesothelial cells of the pleura, peritoneum, pericardium, or tunica vaginalis. - Mesothelioma accounts for 0.10% of deaths annually in the United States. Malignant pleural mesothelioma is the most common of these, comprising of 80% of the cases with an annual incidence of about 2,500 in the United States. - The median survival from diagnosis of pleural mesothelioma is approximately 12 months. The majority of patients present with stage III or IV disease with 85-90% of patients considered unresectable at diagnosis. - Peritoneal mesothelioma has a better prognosis than pleural mesothelioma; nevertheless, patients undergoing therapy for peritoneal mesothelioma have few well-studied treatment options due in large part to the rarity of the disease. Objectives: -To allow sample acquisition for use in the study of mesothelioma. Eligibility: - All patients age greater than or equal to 2 years with malignant mesothelioma - Must be able and willing to provide informed consent if 18 or over; parent or guardian must be able and willing to provide consent for patients under the age of 18 Design: - Up to 1000 subjects will be enrolled. - Patients will be followed to determine the course of disease and to record any treatment received for mesothelioma. - Patients will undergo sampling of blood, urine, tumor and abnormal body fluids for tissue banking. - Studies which may be performed on banked material include genetic and genomic studies, establishment of cell cultures and immunologic studies.
Patients with advanced gastric cancer have showed poor prognosis. Only 81% of the patients could underwent curative surgery. In those, about 60% of patients would survive after 5 years from the surgery. As a result, role of chemotherapy has been increased. In ACTS-GC trial, S-1 adjuvant therapy after D2 gastrectomy increased overall survival rate in advanced gastric cancer patients. However, subgroup analysis showed that S-1 adjuvant therapy was insufficient in patients with stage III or IV (according to the AJCC 6th criteria) gastric cancer. In addition, CLASSIC trial demonstrated that oxaliplatin plus capecitabine adjuvant therapy could increase disease-free survival after D2 gastrectomy in advanced gastric cancer patients. Notwithstanding these trial, optimal adjuvant regimen of advanced gastric cancer has not been established. We aimed to evaluate efficacy of S-1 plus oxaliplatin as adjuvant chemotherapy after D2 gastrectomy in stage III (according to the AJCC 7th criteria) gastric cancer patients.
It is recognized that gastroscopy can miss intestinal metaplasia, dysplasia and early gastric cancer. This could conceivably be due to the fact that these lesions may only present as subtle mucosal changes on conventional white light endoscopy (WLE) and thus be easily missed. In narrow band imaging (NBI) a rotating interference narrow band filter is interposed after the xenon light source such that when the NBI mode is switched on, discrete blue and green wavelengths are used and this improves mucosal surface contrast and facilitates visualization of mucosal details. A new NBI system is available that allows brighter illumination. We hypothesize that bright -NBI is superior to WLE in detecting focal gastric lesions such as gastric intestinal metaplasia, dysplasia and early gastric cancer in subjects undergoing gastroscopy.
1. Introduction The aim of the study is to evaluate the efficacy and safety of ESD by use of a new water-jet assisted ESD system using the HybridKnife® in patients with early gastric neoplastic lesions in comparison to the conventional ESD established in Japan. The water-assisted ESD technology allows pressure controlled injection of fluids through the tip of a recently developed HybridKnife®. Submucosal injection, circumferential cutting and dissection of lesions as well as coagulation of bleeding can be performed with the same device without need for changing the instrument. These options should accelerate the procedure and may increase its safety and efficacy. 2. Hypothesis The water-jet assisted ESD technique using the HybridKnife® bears the advantage of less instrument changes due to the combination of high-frequency cutting and water-jet application in one single instrument. This should lead to a simplified ESD procedure, shorter learn-ing curve and especially to a shorter procedure time. The water-jet assisted ESD technique should be shorter than the conventional ESD techniques using IT2-, Dual- and Hook-Knifes at least with the same safety and effectiveness.
This pilot clinical trial studies copper Cu 64 (64Cu) tetra-azacyclododecanetetra-acetic acid (DOTA)-trastuzumab positron emission tomography (PET)/computed tomography (CT) in studying patients with gastric, or stomach cancer. Diagnostic procedures, such as copper Cu 64-DOTA-trastuzumab PET/CT, may help doctors study the characteristics of tumors and choose the best treatment.
1. Compare the immune response and postoperative complications between pure SIDG (single-incision laparoscopic distal gastrectomy) and TLDG (totally laparoscopic distal gastrectomy) for early gastric cancer (EGC) 2. Validate the safety, usefulness, minimal invasiveness and feasibility of SIDG (EGC)
Enhanced Recovery After Surgery (ERAS) programs have been introduced with purposes of reducing the surgical stress response and obtaining optimal recovery after surgery.
multicenter, open label, randomaized, phase III The role of post surgery adjuvant chemotherapy is becoming more and more important in AGC (advance gastric cancer). S-1 and combined therapy of Capecitabine and Oxaliplatin are currently accepted as a standard therapy among the AGC patients who were performed gastrectomy from the D2 surgery. However, many improvements will be needed in stage IIIB and IV. Combined chemotherapy of Docetaxel, Capecitabine, and Oxaliplatin may be considered as one of the best treatments for IIB and IV(M0) stage AGC patients who were performed gastrectomy.
The purpose of this study is to determine maximal tolerable dose (MTD) of the combination of docetaxel, oxaliplatin and S1 (DOS) to patients with gastric cancer.
