Endoscopic Resection Multicenter Registry

Gastrointestinal NeoplasmsGastrointestinal Disease11 more

This is a retrospective and prospective multicenter registry to collect long-term data (1 year) on patients who have or will undergo Endoscopic resection such as EMR, ESD, EFTR, STER, etc. within the gastrointestinal tract for endoscopic treatment of early gastrointestinal neoplasms involving the resection of the superficial layers, mucosa and submucosa, of the tract wall. Subjects will be consented for medical chart review. The purpose of this retrospective and prospective registry is to assess long term data on efficacy, safety and clinical outcome of Endoscopic Resection within the gastrointestinal tract (1 year). The registry will evaluate efficacy, technical feasibility, clinical outcome, safety profile and overall clinical management through medical chart review. The procedures the investigators are evaluating are all clinically indicated and will not be prescribed to someone to participate in this registry study.

Endoscopic Resection of Gastrointestinal Neoplasms

Endoscopic Mucosal ResectionEndoscopic Submucosal Dissection4 more

The study aims to retrospectively investigate the endoscopic resection procedures of cancerous and precancerous lesions of the upper and lower digestive tract in order to evaluate the efficacy and safety outcomes and to compare different resection techniques. In particular, the resection techniques investigated will be mucosectomy, en bloc and piecemeal, endoscopic submucosal dissection (ESD) and its variants, full-thickness resection. The anatomical districts involved will be the esophagus, stomach, duodenum, colon and rectum.

Postoperative VEGF and Recurrence After Colon Cancer Surgery

AngiogenesisColon Cancer3 more

The purpose of this trial is to study the relationship between the angiogenic response to surgical aggression, determined through the serum levels of vascular endothelial growth factor (VEGF) on postoperative day four, and the tumor recurrence in patients with colon cancer operated with a curative intention.

Da Vinci RobotColon Cancer1 more

The purpose of this study is to compare the clinical data of patients with colon cancer who received robotic or laparoscopic surgery, and to compare the short-term and long-term effects of robotic surgery in the treatment of colon cancer. To verify the safety and effectiveness of the corresponding surgical methods, and provide better guidance for the following clinical practice.

PERCIST Criteria for Response Evaluation With Solid Tumors

Lung NeoplasmsBreast Neoplasms2 more

Chemo-radiotherapy and targeted therapy are widely used as non-surgical treatments for solid tumors. Early assessment of treatment response is considered efficient and helpful to clinical management and personalized therapy.RECIST 1.1 criteria was accepted widely. Complete response (CR), partial response (PR), stable disease (SD), and progressive disease (PD) are defined in the RECIST criteria. This type of classification divides intrinsically continuous data (tumor size) into 4 bins, losing statistical power for ease of nomenclature and convenience. The 18F-FDG PET exam is based on metabolic information and considered to overcome limitations of anatomic imaging and more suitable for assessment of therapeutic response.PERCIST 1.0 proposes a series of detailed and unambiguous regulations about standardization procedures to ensure the reproducibility. Complete metabolic response (CMR), partial metabolic response (PMR), stable metabolic disease (SMD), and progressive metabolic disease (PMD) are defined in the PERCIST criteria. So far, there have several studies using metabolic-based PERCIST criteria in patients with solid tumors, including lung cancer, digestive tumor and lymphoma, etc. But all of these studies had limitations of small study sample, thus were need to be further investigated. Compared to RECIST, the advantages of PERCIST were to evaluate chemotherapy, especially targeted therapy, to distinguish PMR and SMD patients from SD group in RECIST, and to better predict the response rate. Recently, several studies applied PERCIST criteria to evaluate neoadjuvant chemotherapy in pancreatic cancer and rectal cancer, and revealed the metabolic response results were well related to pathology. All these studies conclude PERCIST criteria could help making clinical therapeutic decisions. Moreover, several studies have shown that PERCIST has advantage in predicting early response of several malignant tumors. The aim of this multicenter study is 1) to evaluate treatment response in newly diagnosed and pre-therapeutic patients with solid tumors who are going to receive a baseline , an early follow-up (after a certain period of treatment cycle) and a final (after treatment) 18F-FDG PET/CT; 2) to compared PERCIST criteria to RECIST 1.1 criteria in prediction treatment response, especially in early stage of treatment; 3) to reveal the value of PERCIST criteria in clinical therapeutic management and tailed therapy.

Thymidylate Synthase Polymorphisms as a Predictor of Toxicity to 5-Fluorouracil Based Chemotherapy...

Colon Cancer

Cancer of the colon and rectum are the third most common cancers in Canadian males and females. The initial therapy of colorectal cancer is surgery to remove the cancer and nearby lymph glands. If the cancer has spread to the lymph glands there is a high chance that the cancer will come back. To reduce the risk of the cancer recurring, patients are treated with an anticancer drug 5-fluorouracil (5FU) in combination with a vitamin leucovorin (LV). This study will determine if a simple blood test can predict which patients are at risk for developing side effects from this chemotherapy. In addition, participants of this study will be followed to determine if this same blood test will predict which patients will have their cancer relapse.

BASE HSP110 : A New Therapeutic Target and a New Marker for Prognosis of Type MSI Colorectal Cancer...

Rectum CancerCancer of Colon

We collect prospectively and retrospectively, patients' demographic, pathological, surgical, therapeutic and prognosis informations in a database. After patient's consent to collect tumoural samples of their colorectal cancer after resection. We will then be able to evaluate the impact of HSP110, a chaperon protein, on their prognosis. Other proteins (to be determined) will also be study, after.

Microbiological Spectrum of the Intraperitoneal Surface After Elective Right-sided Colon Cancer...

Peritoneal Contamination After Ileocolonic AnastomosisWound Infection1 more

Despite performing colonic surgery with strict asepsia measures, minimizing the contact of the colon lumen with the peritoneum, some contamination is nearly impossible to avoid. In stapled anastomosis, the hole opened in the colon is minimum, just the necessary for introducing the parts of the mechanical devices. In handsewn anastomosis, the colonic lumen is more exposed to the peritoneum, despite the colonic occlusion with clamps meanwhile the suture is performed. Hypothesis: After stapled anastomoses, the peritoneal contamination should be lower than after handsewn ones.
