Filter by:Recent national surgical quality guidelines (Surgical Care Improvement Project, National Hospital Inpatient Quality Measures)state that removal of urinary catheters should occur by post-operative day two for all surgical patients. These guidelines exclude neither patients who have undergone rectal surgery nor those with epidural analgesic catheters. The common practice among most colorectal surgeons is to leave urinary catheters in for three to five days for patients who have undergone rectal operations, due to concern for urinary retention. This study aims to explore the outcomes of following the national surgical guidelines for early urinary catheter removal, especially with regards to urinary retention and urinary tract infection.
This trial is for patients with colon cancer, head and neck cancer and lung cancer that has not responded to standard therapy. Cetuximab targets a receptor on cancer cells called the Epidermal Growth Factor Receptor or EGFR. It is thought that this receptor is turned "on" in some cancers, enabling cancer cells to divide and grow. Blocking this receptor can turn this signal off. Cetuximab blocks this receptor from the outside of cancer cells. It is thought that cancer cells can turn this signal back on by the EGFR joining with a related receptor called ErbB2. Lapatinib blocks both EGFR and ErbB2 from the inside of cancer cells. In laboratory experiments it has been found that combining drugs that target both EGFR and ErbB2 might work better in turning this signal back off. The purpose of this study is to determine the maximum dosages that patients can tolerate when these two medicines are given at the same time. In addition, in order to be on this trial, patients must agree to have a tumor biopsy before starting treatment on this study and 21 days after starting treatment. These biopsies are a required part of the study. Patients must also agree to have blood drawn for research testing to see whether genetic differences between patients explain different reactions to and side effects from, these medicines.
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.
This study is being done to determine the maximum dose of a certain chemotherapy drug (irinotecan) that can be tolerated as part of a combination of drugs. There is a combination of chemotherapy drugs typically used to treat cancer of the colon and rectum: 5-Flurouracil (5-FU), leucovorin, and irinotecan; the combination is known as FOLFIRI. At the present time, the Food and Drug Administration (FDA) has approved this drug combination for the treatment of cancers of the colon and rectum. The FDA has also approved the use of a drug called bevacizumab (or Avastin) in combination with FOLFIRI, and this is considered one of the standards of care for all patients with colon and rectal cancer which has spread. The best dose of irinotecan to use in the combination of FOLFIRI and bevacizumab is not known. Earlier studies have shown that higher doses of irinotecan can be used safely as part of the FOLFIRI combination, but it is unclear whether these same doses will be safe when bevacizumab is added to this combination.
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.
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.
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.
This is a single-arm, open-label, multicentre phase II study evaluating the safety and efficacy of the combination of the G.O.N.O. FOLFOXIRI regimen with bevacizumab as first-line treatment of metastatic colorectal cancer.
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.
