Filter by:The purpose of this study is to compare overall survival in participants with metastatic colorectal cancer treated with either ramucirumab and FOLFIRI or placebo and FOLFIRI.
The aim of this study is to compare the effect of reminding letter and educational intervention on attendance to screening colonoscopy in nonresponders to initial invitation to screening colonoscopy.
The purpose of the study is to investigate whether the information about a doctor or possibility to choose doctor's gender included in invitation letter is associated with attendance rate to screening colonoscopy.
This study will assess the efficacy and safety of intravenous Avastin in combination with chemotherapy regimens as second-line treatment of metastatic cancer of the colon or rectum. The anticipated time of study treatment is until disease progression.
A new approach to treating solid tumours (both operable and inoperable) has been carried out by the Cork Cancer Research Centre (CCRC) at the Mercy University Hospital, Cork, Ireland since 2002. The approach simply allows a greater concentration of chemotherapy drugs to enter the tumour cells rather than healthy cells. The uptake of the chemotherapeutic drug directly by the tumour is aided through applying short electric pulses to the tumor mass (referred to as - Electrochemotherapy or ECT). The pulses make the tumour more porous which allows the drug easier access into the cancer cells, whereas other tissues and organs in the body remain relatively poor at absorbing the drug, thereby reducing the potential side effects on healthy tissues. This approach to date has been limited to skin based tumours due to the requirement for the electrodes to be placed directly in contact with the tumour. Procedures with electrochemotherapy have been applied to human patients in other countries of the EU, the US and Japan. The drug concentration used is significantly reduced due to the more targeted absorption by the tumor and this significantly reduces side effects normally associated with chemotherapy. A large number of preclinical and clinical Phase I and I/II studies have demonstrated the efficiency and safety of ECT. These studies have included patients with melanoma, head and neck squamous cell carcinoma, merkel cell carcinomas, basal cell carcinoma and adenocarcinoma nodules. Case reports concerning other primary tumours have also been reported. The investigators have developed an endoscopic approach (EndoVe system) for delivering the electric pulses to internal cancers and are currently seeking to evaluate its efficacy in the treatment of inoperable colorectal cancer. The treatment procedure is similar to standard endoscopic colorectal examination (colonoscopy) with the added element of an intravenous injection of bleomycin followed after eight minutes by the delivery of electric pulses (each one less than 1msec in duration). The pulses are endoscopically delivered directly to the tumour mass. The entire procedure is minimally invasive and does not require intensive care follow up or stitches. If the treatment is successful the tumour will shrink in size in the weeks following the procedure. The objective of this study is to investigate the efficacy and safety of this approach in reducing the size of the tumour.
RATIONALE: Fiber may lessen bowel side effects caused by radiation therapy. It is not yet known whether a high-fiber diet is more effective than a low-fiber diet in preventing bowel side effects caused by radiation therapy. PURPOSE: This randomized clinical trial is studying a high-fiber diet to see how well it works compared with a low-fiber diet in preventing bowel side effects in patients undergoing radiation therapy for gynecological cancer, bladder cancer, colorectal cancer, or anal cancer.
This expanded access study will assess the efficacy and safety of intravenous Avastin (5 mg/kg every 2 weeks or 7.5 mg/kg every 3 weeks) in combination with fluoropyrimidine-based chemotherapy as first line treatment of patients with metastatic cancer of the colon or rectum. The anticipated time on study treatment is 3-12 months.
RATIONALE: Drugs used in chemotherapy work in different ways to stop the growth of tumor cells, either by killing the cells or by stopping them from dividing. Heating mitomycin C to several degrees above normal body temperature and infusing it into the area around the tumor may kill more tumor cells. Giving mitomycin C after surgery may kill any remaining tumor cells. It is not yet known whether standard therapy is more effective with or without surgery followed by mitomycin C. PURPOSE: This randomized phase III trial is studying standard therapy with or without surgery and mitomycin C in treating patients with advanced limited peritoneal dissemination of colon cancer
RATIONALE: Drugs used in chemotherapy, such as fluorouracil, oxaliplatin, and leucovorin calcium, work in different ways to stop the growth of tumor cells, either by killing the cells or by stopping them from dividing. Giving more than one drug, combination chemotherapy, may kill more tumor cells. Studying samples of blood in the laboratory from patients with cancer receiving fluorouracil in combination with oxaliplatin and leucovorin calcium may help doctors learn how fluorouracil works in the body and how patients will respond to treatment. PURPOSE: This phase I trial is studying biomarker-guided fluorouracil in treating patients with colorectal cancer receiving combination chemotherapy.
The purpose of this study is to identify an early indicator of drug efficacy in patients with advanced colorectal cancer - a prospective evaluation of circulating tumor cells, positron-emission tomography scan and RECIST criteria.
