Filter by:National, multi-center, open-label,randomized, 2-arm phase III superiority trial, comparing neoadjuvant chemotherapy (CT) with mFolfirinox followed by preoperative chemoradiotherapy (CRT), versus preoperative CRT in patients with locally advanced rectal cancer.
The aim of this study is to decrease the morbidity by 30% using the Turnbull-Cutait procedure in comparison to the standard surgery for low rectal cancer. The investigators compare quality of life, faecal incontinence and recurrence of neoplasm in patients who received standard colo-anal anastomosis with protective ileostomy or two-staged Turnbull-Cutait colo-anal anastomosis after Low Anterior Resection for rectal cancer.
This phase II trial studies how well giving aflibercept together with combination chemotherapy works in treating patients with previously untreated colon or rectal cancer that is metastatic or locally advanced and cannot be removed by surgery. Aflibercept may stop the growth of colon or rectal cancer by blocking blood flow to the tumor. Drugs used in chemotherapy, such as leucovorin calcium, fluorouracil, and oxaliplatin, work in different ways to stop the growth of tumor cells, either by killing the cells or by stopping them from dividing. Giving aflibercept together with combination chemotherapy may kill more tumor cells
To investigate the feasibility of preoperative chemoradiation with oxaliplatin plus capecitabine, with or without prior induction chemotherapy in patients with locally advanced or marginally resectable rectal cancer with resectable synchronous liver metastases.
Currently the 3-year disease free survival of patients with locally advanced rectal cancer is about 50%. Current standard treatment for patients at high risk of failing locally and/or systemically includes pre-operative long course radiotherapy (5 weeks) in combination with chemotherapy (so called neoadjuvant chemoradiotherapy). The neoadjuvant chemoradiotherapy has been demonstrated to improve local control, but had no effect on the overall survival. Different studies in patients with rectal cancer studying the effect of adjuvant post operative chemotherapy did not result in an improved survival. This may be due the fact that rectal cancer surgery (TME) is associated with a high complication rate so substantial proportion of patients cannot receive chemotherapy postoperatively. An alternative approach is to administer the systemic therapy preoperative. To guarantee control of the rectum tumor short-course radiotherapy (5 days) is given, as different studies showed local control of the tumor for a long time. During this waiting period the patient is in a good condition to receive an optimal dose of chemotherapy. The investigators hypothesize that with this proposed protocol both the local tumour and possible micrometastases are effectively treated and that this will result in an increased survival. The investigators will compare this with the standard treatment of neoadjuvant chemoradiation followed by TME surgery and optional adjuvant chemotherapy.
The standard treatment for locally advanced rectal cancer involves chemotherapy and radiation, known as 5FUCMT, (the chemotherapy drugs 5-fluorouracil/capecitabine and radiation therapy) prior to surgery. Although radiation therapy to the pelvis has been a standard and important part of treatment for rectal cancer and has been shown to decrease the risk of the cancer coming back in the same area in the pelvis, some patients experience undesirable side effects from the radiation and there have been important advances in chemotherapy, surgery, and radiation which may be of benefit. The purpose of this study is to compare the effects, both good and bad, of the standard treatment of chemotherapy and radiation to chemotherapy using a combination regimen known as FOLFOX, (the drugs 5-fluorouracil (5-FU), oxaliplatin and leucovorin) and selective use of the standard treatment, depending on response to the FOLFOX. The drugs in the FOLFOX regimen are all FDA (Food and Drug Administration) approved and have been used routinely to treat patients with advanced colorectal cancer.
Rectal cancer is a common type of cancer occuring more frequently in men but also common in women. Almost 60% of the patients survive 5-years and the treatment has been continuously developed in the last three decades. The aim of the QoLiRECT study is to increase the knowledge about symptoms, functional impairments, quality of life (QoL) and psychological and socioeconomic burden in an unselected population of rectal cancer patients.
Sphincter preservation surgery in low rectal cancer has been increased due to better understanding of tumor biology and advances in surgical technology. Furthermore, a majority of patients prefer sphincter preservation rather than living with permanent colostomy. But it is not clear whether sphincter preservation is directly related with better quality of life. There have been many studies comparing sphincter preservation surgery and abdominoperineal resection in many aspects including oncologic and functional outcomes, and the quality of life. However, the conclusion remains controversial because of the different results between studies.
The trial compares two different techniques for reconstruction of the lesser pelvic floor after an extended abdominoperineal excision for locally advanced rectal cancer. The alternative reconstruction techniques in the trial are: - a technique using a gluteus maximus myocutaneous flap or - a technique using an acellular porcine collagen implant (biological mesh) The primary endpoint will be physical performance six months from operation and our hypothesis is that the technique using an acellular porcine implant will cause less impaired physical performance compared to the technique using a myocutaneous flap. The study is interventional, randomized and by definition a comparative effectiveness research project.
The objective of this trial is to obtain evidence that, in patients with RAS wildtype tumors, a chemotherapy-free combined modality treatment with panitumumab is clearly superior to radiotherapy alone and achieves a pCR rate comparable to that after radiochemotherapy including two-drug combinations while reducing the toxicity compared to these two-drug regimens.
