Active clinical trials for "Rectal Neoplasms"

The hypothesis is that intraoperative radiotherapy for locally advanced or recurrent rectal cancer improve outcomes without causing significant side effects.

The purpose of this study is to determine whether topical nitroglycerin in addition to 5-flourouracil and radiation therapy are effective in the treatment of operable rectal cancer.

This phase I trial studies the side effects and best dose of sorafenib tosylate when given together with bevacizumab, irinotecan hydrochloride, leucovorin calcium, and fluorouracil in treating patients with colorectal cancer that has spread to other parts of the body. Drugs used in chemotherapy, such as irinotecan hydrochloride, leucovorin calcium, and fluorouracil, work in different ways to stop the growth of tumor cells, either by killing the cells, by stopping them from dividing, or by stopping them from spreading. Sorafenib tosylate may stop the growth of tumor cells by blocking some of the enzymes needed for cell growth. Monoclonal antibodies, such as bevacizumab, may interfere with the ability of tumor cells to grow and spread. Sorafenib tosylate and bevacizumab may also block tumor growth in different ways by targeting certain cells. Giving sorafenib tosylate and bevacizumab together with combination chemotherapy may be a better treatment for colorectal cancer.

This phase II trial studies how well RO4929097 works in treating patients with metastatic colorectal cancer. RO4929097 may stop the growth of tumor cells by blocking some of the enzymes needed for cell growth.

The aim is to study safety and activity of nelfinavir , added to standard chemoradiotherapy in patients with locally advanced rectal cancer. Furthermore analysis of the effect of nelfinavir combined with chemoradiation on tumour tissue will be studied

To assess the efficacy and safety of pre-operative capecitabine and oxaliplatin followed by capecitabine with concurrent radiotherapy followed by post-operative capecitabine in the treatment of patients with locally advanced or inoperable rectal cancer.

Primary objective: Pathological complete response (ypT0N0) rate Secondary objectives: Histopathological R0 resection rate Pathological downstaging (ypT0-T2N0) rate One month surgical complication rate Predictive value of pre-operative MRI for surgical, pathological and clinical outcomes Safety Local and distant recurrence rates Progression-free survival Overall survival

To determine if short course radiotherapy followed by chemotherapy can maintain morbidity at or below levels reported with concurrent 5FU, oxaliplatin, and radiotherapy, while maintaining response rates comparable to what would be expected with radiotherapy and concurrent chemotherapy.

The primary objective was to improve adjuvant 5-FU chemoradiotherapy in resectable rectal cancer. The investigators hypothesis was that modulation of 5-FU by addition of either FA or INF-alpha may increase overall survival.

The purpose of the study is to evaluate the efficacy and safety of the combination of capecitabine + bevacizumab concomitantly with radiotherapy versus capecitabine concomitantly with radiotherapy, as neoadjuvant treatment for patients with localized and resectable rectal cancer.
