Filter by:This study involves standard combination chemotherapy treatment for colon cancer, 5-Fluorouracil (5FU), leucovorin and irinotecan (known as FOLFIRI), plus bevacizumab (Avastin). The study is designed to test the FOLFIRI regimen based on certain characteristics of a person's genetic makeup or "genes". Genes are made of DNA and determine not only inherited traits or appearance (hair and eye color, height, body type, etc.) but also play an important role in health and how the body responds to illness and treatments for those illnesses. In this study, the investigators will examine the relationship between a patient's genes (DNA), or "genotype", and how the patient's body breaks down and removes or "metabolizes" the anti-cancer drug irinotecan. Circulating blood level of irinotecan plays an important role in how well this drug works against a patient's cancer as well as the adverse side effects the patient may experience. The current standard dose of irinotecan was determined in clinical trials without knowing individual genotypes and thus does not take into account a patient's ability to metabolize irinotecan. This means that based on one genotype the current standard dose of irinotecan may be correct or based on other genotypes the standard dose could result in lower and possibly less effective blood levels and result in significant under-dosing of irinotecan. Based on genotype the patient will be assigned to one of the following doses of irinotecan: - 180 mg/m2 (standard dose) - 260 mg/m2 - 310 mg/m2 The purpose of this research study is to determine if dosing irinotecan based on genotype is effective and safe for patients with colon cancer. Patient genotype will be determined from a small sample of blood and a laboratory test or "assay" performed at UNC Laboratories. For the purpose of this study, this assay is new and considered to be "investigational". This means that the genotype assay used in this study has not yet been approved by the FDA for determining irinotecan dose levels in patients with colon cancer.
The purpose of this study is to compare 3 cycles of neoadjuvant (preoperative) chemotherapy + operation with the standard treatment of locally advanced colon cancer, which is operation + 8 cycles of (adjuvant) chemotherapy. Patients receiving neoadjuvant chemotherapy may not need adjuvant chemotherapy after the operation and, if this is the case, they will be spared of 5 cycles of chemotherapy.
Primary objective of the study is to compare requirement of blood transfusion and mortality in patients receiving Tranexamic acid (Cyklokapron®) and those not receiving it. Secondary objective is to; assess the re-bleeding events; need for surgical intervention; length of stay in Intensive care unit in between the two groups.
The investigators are investigating the usefulness of 18F-Fluordeoxyglucose Positron Emission Tomography/ Computed Tomography (18F-FDG PET/CT) for staging and follow-up of colon cancer. Furthermore, the investigators combine 18F-FDG PET findings with clinical and histopathological features, circulating tumor cell (CTC) analyses, tumor gene expression and measurements of circulating cancer biomarkers sUPAR, TIMP-1 and CEA in order to predict tumor recurrence. The investigators hypothesis: The combination of functional imaging by 18F-FDG PET/CT and pre-existing and evolving molecular biomarkers will optimize tumor characterization, staging of disease and early detection of recurrence.
This is a prospective randomized study of 114 patients. The purpose of this study is to compare the efficacy of two standard methods of analgesia for pain control in patients undergoing elective colon and rectal surgery, as measured by the Numeric Pain Scale (NPS) and by the need for supplemental narcotic analgesics. This study is designed to determine if postoperative pain control by local analgesics delivered through preperitoneally placed ON-Q Silver SoakerTM catheters (CPA) is equivalent to continuous epidural analgesia (CEA).
This study is a parallel translational study of a Randomized Phase III trial Investigating the Role of Oxaliplatin duration (6 Cycles Versus 12 Cycles) in modified FOLFOX-6 Regimen as Adjuvant Therapy for Patients with Stage II/III Colon Cancer (MIDAS trial: protocol NCCCTS-467) . Patients participating in the trial will be provided with the informed consent of this parallel study, and peripheral blood and tumor tissue of those who signed the consent will be collected for germline polymorphism analysis and gene expression profile study .
This study sets up the final study end point and three detailed goals as the following. The main objective of study: This trial is done to assess the safety and benefit of early adjuvant chemotherapy from 10 to 14 days after surgery compared with conventional commencement after 2weeks for treatment of patients with colon cancer. Detailed goal of study: The primary endpoint: This study is designed to assess whether early commencement of adjuvant chemotherapy improves the 3-year disease-free survival, overall survival and recurrence rate. The secondary endpoint: This study aims to compare short-term cumulative complications between early and conventional commencement of adjuvant chemotherapy after laparoscopic resection of colon cancer. This study will also assess the quality of life and side effects of chemotherapy.
This study is designed to confirm that first 3 months of oxaliplatin in 6 months of modified FOLFOX-6 or CAPOX treatment is not inferior to 6 months of oxaliplatin in modified FOLFOX-6 or CAPOX treatment in terms of disease free survival in patients with stage II/III colon cancer.
This study will look for new types of gene changes that may be related to cancer in some patients. Some gene changes (mutations) are passed on from parents to offspring (child). Other gene changes are new and are seen for the first time in a child. They are not seen in the parent. Some of these gene changes may cause cancers in the offspring. We will look for gene changes by studying patients with cancer their parents and family members without cancer. In this study, we will be able to find gene changes that occur in the cancer patient but not in the rest of the family. Knowing the role that new gene changes play in cancer risk may help us find people at a higher risk of getting cancer.
The purpose of this study is to provide educational material to promote screening for second primary cancer for the intervention group, or educational material to instruct appropriate use of dietary supplement for the control group.
