Active clinical trials for "Rectal Neoplasms"

Phase II clinical trial, open-label, randomized, two arms, multicentre (possibly multinational). Academic, investigator initiated. To assess the activity of bevacizumab (AvastinTM) in combination with capecitabine (XelodaTM) and radiation therapy with or without oxaliplatin (EloxatinTM) in the pre-operative treatment of locally advanced rectal cancer, followed by TME (total mesorectal excision).

This phase II trial is studying how well giving sorafenib together with bevacizumab works in treating patients with metastatic colorectal cancer. Sorafenib may stop the growth of tumor cells by blocking some of the enzymes needed for cell growth. 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. Sorafenib and bevacizumab may also stop the growth of tumor cells by blocking blood flow to the tumor. Giving sorafenib together with bevacizumab may kill more tumor cells

This phase 1/2, multi-center, randomized, double-blind, placebo-controlled trial is designed to evaluate the efficacy and safety of AMG 655 when combined with mFOLFOX6 and bevacizumab compared with mFOLFOX6 and bevacizumab alone in subjects with previously untreated metastatic colorectal cancer (CRC). The clinical benefit of AMG 655 in combination with mFOLFOX6 and bevacizumab will be measured by progression-free survival, objective response rate, time to response, duration of response, and overall survival. This study is also designed to evaluate the safety and tolerability of AMG 655 in combination with mFOLFOX6 and bevacizumab and to evaluate anti-AMG 655 antibody formation and the pharmacokinetics of AMG 655.

RATIONALE: Drugs used in chemotherapy, such as oxaliplatin and capecitabine, 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 cetuximab, 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. Radiation therapy uses high-energy x-rays to kill tumor cells. Giving chemotherapy and radiation therapy before surgery may make the tumor smaller and reduce the amount of normal tissue that needs to be removed. PURPOSE: This phase II trial is studying the side effects and how well giving oxaliplatin, capecitabine, and cetuximab together with radiation therapy followed by surgery works in treating patients with stage II or stage III rectal cancer.

The purpose of this study is to evaluate the of international standard operation, mesorectal excision (ME alone) compared to Japanese standard operation, ME with lateral lymph node dissection for clinical stage II, III lower rectal cancer

RATIONALE: Radiation therapy uses high-energy x-rays to kill tumor cells. Drugs used in chemotherapy, such as capecitabine 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 more than one drug (combination chemotherapy) may kill more tumor cells. Giving radiation therapy together with combination chemotherapy before surgery may shrink the tumor so it can be removed. It is not yet known whether giving radiation therapy together with capecitabine is more effective with or without oxaliplatin before surgery in treating rectal cancer. PURPOSE: This randomized phase III trial is studying radiation therapy, capecitabine, and oxaliplatin to see how well they work compared to radiation therapy and capecitabine in treating patients who are undergoing surgery for stage II or stage III rectal cancer.

For patients who have one or two metastases in the brain, the tumor(s) can often be removed with surgery to relieve symptoms from the tumor(s) and to improve survival. However, about half of all patients who have the tumor(s) removed with surgery will develop regrowth (recurrence) of the tumor. To prevent this regrowth of tumor, some patients receive radiation to the entire brain (whole brain radiation) after surgery. This involves daily treatment for about two to three weeks, and may cause long-term neurological problems, such as memory loss. Stereotactic radiosurgery (SRS) is sometimes used instead of surgery to treat brain metastasis. This involves the use of a special head frame and sophisticated computer programs that enable us to deliver a high dose of radiation to a small focused area of the brain in only one treatment. Research has shown that the results of treatment with SRS are as good as surgical removal of the tumor. SRS and surgical resection are considered the standard options for the treatment of brain metastases. This Phase II clinical trial is studying the combination of these two techniques. The purpose of this study is to evaluate the use of SRS following surgical removal of brain metastases. The outcomes we will be looking at are tumor regrowth after treatment and side effects of treatment.

The purpose of this research study is to find out what effects (good and bad) cetuximab has on rectal cancer.

This phase II trial studies how well giving bevacizumab, radiation therapy, and combination chemotherapy works in treating patients who are undergoing surgery for locally advanced nonmetastatic rectal cancer. Monoclonal antibodies, such as bevacizumab, can block tumor growth in different ways. Some find tumor cells and kill them or carry tumor-killing substances to them. Others interfere with the ability of tumor cells to grow and spread. Bevacizumab may also stop the growth of tumor cells by blocking blood flow to the tumor. Radiation therapy uses high-energy x-rays to kill tumor cells. Drugs, such as capecitabine, may make tumor cells more sensitive to radiation therapy. Drugs used in chemotherapy, such as capecitabine, oxaliplatin, fluorouracil, and leucovorin, work in different ways to stop the growth of tumor cells, either by killing the cells or by stopping them from dividing. Giving bevacizumab together with radiation therapy and combination chemotherapy before surgery may make the tumor smaller and reduce the amount of normal tissue that needs to be removed. Giving bevacizumab together with combination chemotherapy after surgery may kill any tumor cells that remain after surgery.

This randomized phase I/II trial studies the side effects, best way to give, and best dose of erlotinib and bevacizumab when given with cetuximab and how well giving erlotinib and cetuximab together with or without bevacizumab works in treating patients with metastatic or unresectable kidney, colorectal, head and neck, pancreatic, or non-small cell lung cancer. Erlotinib may stop the growth of tumor cells by blocking some of the enzymes needed for cell growth. Monoclonal antibodies, such as cetuximab and 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. Cetuximab and bevacizumab may also stop the growth of tumor cells by blocking blood flow to the tumor. Giving erlotinib together with cetuximab and/or bevacizumab may kill more tumor cells.
