Filter by:RATIONALE: Drugs used in chemotherapy, such as irinotecan hydrochloride, work in different ways to stop the growth of tumor cells, either by killing the cells or stopping them from dividing. Chemoembolization kills tumor cells by blocking blood flow to the tumor and keeping chemotherapy drugs near the tumor. PURPOSE: This phase II trial is studying how well chemoembolization using irinotecan works in treating patients with liver metastases from metastatic colon or rectal cancer.
This study combines midostaurin (PKC412) with radiation and a standard chemotherapy drug call 5-Fluorouracil (5-FU) for subjects with advanced rectal cancer. Midostaurin is a type of kinase inhibitor which works by blocking proteins associated with cancer cell growth. Previous studies also suggest that midostaurin may help increase the effectiveness of radiation therapy. In this research we are looking for the highest dose of midostaurin that can be given safely in combination with standard chemoradiation.
This study is proposed to evaluate whether giving part of the chemotherapy prior to radiotherapy and surgery (as opposed to standard of care, which involves giving all the chemotherapy after radiotherapy and surgery) for patients with node positive operable rectal cancer will result in higher patient compliance to chemotherapy.
In the Netherlands approximately 2300 new patients are diagnosed with rectal cancer each year. Standard treatment for patients with a T2 or T3 rectal cancer consists of preoperative short course of radiotherapy followed by surgery. In advanced cases long course of radiotherapy combined with chemotherapy is used instead of a short cause. In some of these advanced cases a complete remission is observed after a long course of radio-/chemotherapy. Patients who respond well to neo-adjuvant treatment carry a better prognosis. Objective of this research is to evaluate whether neo-adjuvant chemo-/radiotherapy in small non-advanced rectal cancers can be used to obtain a complete or near complete remission. In these patients could a complete resection of the rectum as an organ be avoided by treating them with a local excision with the TEM-technique (Transanal Endoscopic Microsurgery) of the scar. The advantage for these patients is, that they do not need major abdominal surgery and in a substantial number of these patients the rectum can be preserved with a better function of continence.
This phase II clinical trial is studying how well giving combination chemotherapy and bevacizumab with or without RO4929097 works in treating patients with metastatic colorectal cancer. Drugs used in chemotherapy, such as oxaliplatin, leucovorin calcium, and fluorouracil, work in different ways to stop the growth of tumor cells, either by killing the cells or by stopping them from dividing. Monoclonal antibodies, such as bevacizumab, can block tumor growth in different ways. Some block the ability of tumor cells to grow and spread. Others find tumor cells and help kill them or carry tumor-killing substances to them. RO4929097 may stop the growth of tumor cells by blocking some of the enzymes needed for cell growth. It is not yet known whether combination chemotherapy and bevacizumab is more effective with RO4929097 in treating patients with colorectal cancer.
After rectal excision, the rate of anastomotic leak and abscess is higher than after colic surgery. In order to limit and avoid the risk of pelvic sepsis after rectal excision, a prophylactic pelvic drainage is usually used. If current data have confirmed the uselessness of drainage in colic surgery, the question stay in abeyance in rectal surgery. This practice had never been evaluated in patients with rectal excision and low anastomosis (patients with a high risk of pelvic sepsis)
The purpose of this study is the increase of resection rate of primary cancer in rectal after short course radiotherapy without interrupt chemotherapy schedule during the period of chemotherapy. The subject should have the pathologically confirmed for unresectable (impossible to try Total mesorectal excision) rectal cancer with liver metastasis. This trial contributes to save the time for decreasing primary tumor in rectal and metastasis cancer to whole body after short course radiotherapy.
This is an open-label, randomized phase II study. Patients will be randomly assigned to either FL or TS-1/irinotecan preoperative chemotherapy regimens by stratification. Patients in FL group will be treated with bolus injections of 5-FU 400 mg/m2/day and LV 20 mg/m2/day for 3 consecutive days every 4 weeks for 2 cycles, and patients in TS-1/irinotecan will be treated with irinotecan 40 mg/m2/day on days 1, 8, 15, 22, 29. TS-1 at a dose of 35mg/m2 was administered orally twice a day after a meal on the day of irradiation (Monday-Friday) concurrent with radiotherapy.
The purpose of this study is to seek the proper dose of capecitabine in post-operative concurrent chemotherapy for stage II/III elderly rectal cancer patients receiving radical surgery, and evaluate the toleration of this modality in such patients.
RATIONALE: Drugs used in chemotherapy, such as oxaliplatin, leucovorin, and fluorouracil, work in different ways to stop the growth of tumor cells, either by killing the cells or by stopping them from dividing. Radiation therapy uses high-energy x-rays to kill tumor cells. Giving chemotherapy before surgery may make the tumor smaller and reduce the amount of normal tissue that needs to be removed. Giving chemotherapy after surgery may kill any tumor cells that remain after surgery. PURPOSE: This phase II trial is studying giving oxaliplatin, leucovorin, and fluorouracil together, before and after radiation therapy and surgery in treating patients with rectal cancer that can be removed by surgery.
