Filter by:Some subtypes of gastric and cardia tumors such as adenocarcinoma or gastric linitis with disseminated cells respond poorly to the pre-operative chemotherapy, and some of them do not respond to chemotherapy usually performed. Doing chemotherapy in these patients could delay their surgical management. The completion of chemotherapy for these patients would be a bad prognosis factor according to recent data from the literature. Therefore, the aim of this research is to find prognostic markers of sensitivity to chemotherapy usually performed. The investigators are going to use biopsies realized at diagnosis and select patients "good and bad" responders. Primary purpose: To study cardia and gastric tumors, molecular markers sensitivity to pre- and post- perative chemotherapy protocols (EOX protocol ... FOLFOX) or chemoradiation Secondary purposes: - To assess the impact of patients' lifestyle (via a questionnaire) on the response to chemotherapy - To study markers of cancer stem cells - To correlate clinical and molecular markers with patient survival and quality of life questionnaires - To characterize the expression levels (Met, Her2, FGFR2) and mutations (p53 ras) in frequently deregulated genes in gastric cancers. - To characterize the level of expression of predictive candidate markers (ΔNp73, TAp73, HDAC4, mir140, EZH2, CXCL12, CXCR4, CXCR7) found in the literature. - To correlate the abnormalities found in the with tumor stages (before and after chemotherapy) and with 5 years overall survival and progression-free patients
The purpose of this study is evaluation of the safety and the efficacy of transanal local excision in patients with cT3 rectal cancer which was downstaged into ycT0-1 after neoadjuvant chemoradiotherapy.
This is a non-randomized pauci-centre, open-label phase II study. The treatment will consist in a chemotherapy by FOLFOX and nab-paclitaxel following modalities determined in the Brown University Phase I study. In neoadjuvant setting : 3 months of treatment Main criteria of Withdraw of the treatment: in case of tumor progression, non acceptable toxicity, or patient decision. Post-operative treatment (for 6 additional cycles) is recommended, but will depend on the result of the neo-adjuvant treatment and the ability of patients to receive adjuvant chemotherapy based on tolerance of neo-adjuvant treatment and general post-operative condition (i.e. adjuvant treatment if no progression during neo-adjuvant chemotherapy, less than 80% of residual viable tumor compared to initial tumor volume, acceptable tolerance and post-operative PS 0 - 2). Adjuvant treatment must be initiated within 8 weeks post-operatively.
The primary purpose of this study is to test new methods to diagnose BE in time before it turns into advanced cancer. Once BE is diagnosed, the current standard of care is to monitor the disease so that complication such as cancer can be diagnosed early. The two new methods the investigators are evaluating are: a) blood test and b) brush test of the food pipe. The investigators will collect blood, bile and cells from the food pipe and stomach and measure for a biomarker called microRNA (miRNA). In the future, measurements of microRNA biomarkers could help the doctors figure out which patients are at increased risk for cancer of the esophagus.
This platform trial will evaluate various immunotherapy combinations given in the neo-adjuvant and adjuvant setting in patients with surgically resectable pancreatic ductal adenocarcinoma.
This pilot clinical trial studies genetic analysis-guided irontecan hydrochloride dosing of modified fluorouracil, irinotecan hydrochloride, leucovorin calcium, oxaliplatin (mFOLFIRINOX) in treating patients with gastroesophageal or stomach cancer that has spread from where it started to nearby tissue or lymph nodes. Drugs used in chemotherapy, such as fluorouracil, irinotecan hydrochloride, leucovorin calcium, and oxaliplatin, work in different ways to stop the growth of tumor cells, either by killing the cells, by stopping them from dividing, or by stopping them from spreading. Leucovorin calcium may also help fluorouracil work better. Genetic analysis may help doctors determine what dose of irinotecan hydrochloride patients can tolerate.
Colorectal cancer occurs mainly in elderly patients. Recent estimation showed that in France more than 50% of the patients diagnosed with a colorectal cancer are 70 years old or more. Adjuvant chemotherapy has demonstrated a benefit on disease-free survival and overall survival after a stage III colon cancer resection. Nevertheless adjuvant chemotherapy is poorly used in elderly patients. Prognostic improvement with chemotherapy based on 5FU is suggested by a post-hoc analysis of randomized prospective clinical trial. But elderly patients in this study were highly selected and patients older than 80 represented only 0.7% of the total population. Thus, there is still a concern about the benefit of adjuvant 5FU-based chemotherapy in very elderly unselected patients. The recommended treatment for stage III adjuvant chemotherapy is a combination of fuoropyrimidine and oxaliplatin. Nevertheless oxaliplatin did not demonstrated survival advantage in elderly patients. Altogether there are still two matters of debate: - First, is there a benefit of fluoropyrimidine-based adjuvant chemotherapy for unfit elderly patients? - Second, is there a benefit of oxaliplatin-based adjuvant chemotherapy for fit elderly patients? The aim of this randomized phase III study is to evaluate the benefit for disease-free survival of adjuvant chemotherapy in elderly patient and which chemotherapy. The elderly patient population will be dichotomized into two groups according to physician's choice after a multidisciplinary evaluation involving a geriatrician, with two different randomization assignments. The patients with an expected life-expectancy below 4 years according Lee score are excluded of this study. Some biological tumour abnormalities are more frequently observed in elderly (i.e. mismatch repair deficiency), therefore an evaluation of specific biological prognostic factors is needed in elderly population.
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.
All patients with recurrent colorectal cancer in the pelvis are eligible. The original primary tumour staging scans and resected surgical specimen needs to be available. Patients' recurrence will be staged using our proposed MRI classification. We will be assessing the original primary staging scans and histopathology to learn about risk factors for recurrence. We will record treatment for the recurrence, and patients will be followed up for three years.
The purpose of this study is to compare early-stage peripheral non-small cell lung cancer lobectomy and sub-lobectomy surgery to evaluate if sub-lobectomy is as feasible and effective for the treatment of early-stage (diameter ≤2cm) peripheral non-small cell lung cancer as lobectomy.
