Filter by:The local recurrence of rectal cancer is one of the main problem that fail the treatment. The preoperative neoadjuvant (chemo)radiotherapy has been confirmed to reduce the local recurrence rate,especially in the advanced rectal cancer. However the local recurrence rate is low about 10-20% totally,and the integrity of the mesorectum after the operation and circumferential resection margin(CRM) are the most critical factor for the local recurrence.So that, the advanced rectal cancer patients with negative CRM and had a complete mesorectum excision,may not benefit from the neoadjuvant radiation.This trial was mainly focus on the resectable advanced rectal cancer patients whose preoperative stage was cT3/N+. These patients will be divided into the lower risk group and higher risk group according the preoperative CT,Endoscopic ultrasound, and MRI,and carrying out randomized trial in the two groups respectively.The purpose of this trial is to confirm whether the preoperative radiotherapy is necessary for all the advanced rectal cancer patients,identify the reason of the local recurrence,and finally help the making of the treatment decision for the advanced resectable rectal cancer.
The purpose of this study is to determine whether Alkagin paste is effective at preventing radiodermatitis in patients receiving external beam radiation therapy to the perineal area.
This phase II trial studies how well Linifanib works in treating patients with advanced, refractory colorectal cancer expressing k-Ras mutations. Linifanib may stop the growth of tumor cells by blocking some of the enzymes needed for cell growth.
The purpose of the Phase Ib portion is to find out the highest dose of study drug that can safely be given when tested in a small group of subjects. The purpose of the Phase II portion is to find out how safe the study drug is when taken at the highest dose in a larger group of subjects.
This phase II trial studies how well giving combination chemotherapy and bevacizumab before surgery and radiolabeled monoclonal antibody therapy works in treating liver metastases in patients with metastatic colorectal cancer. Drugs used in chemotherapy, such as leucovorin calcium, fluorouracil, and oxaliplatin (FOLFOX), 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 to grow and spread. Others find tumor cells and help kill them or carry tumor-killing substances to them. Radiolabeled monoclonal antibodies, such as yttrium Y 90 DOTA anti-CEA monoclonal antibody M5A, can find tumor cells and carry tumor-killing substances to them without harming normal cells. Giving chemotherapy and monoclonal antibody before surgery may make the tumor smaller and reduce the amount of normal tissue that needs to be removed. Giving radiolabeled monoclonal antibody therapy after surgery may kill any tumor cells that remain after surgery
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.
The primary purpose of the study is to investigate 18F-FAZA-PETs role as predictor of response to neoadjuvant chemoradiation of locally advanced rectum cancer.
Panobinostat may stop the growth of tumor cells by blocking some of the enzymes needed for cell growth. Drugs used in chemotherapy, such as fluorouracil 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 panobinostat together with fluorouracil and leucovorin calcium may kill more tumor cells. PURPOSE: This phase I trial is studying the side effects and the best dose of giving panobinostat, fluorouracil, and leucovorin calcium together in treating patients with stage IV colorectal cancer who did not respond to previous fluorouracil-based chemotherapy.
This phase I trial is studying the side effects and the best dose of veliparib when given together with capecitabine and oxaliplatin in treating patients with advanced solid tumors. Veliparib may stop the growth of tumor cells by blocking some of the enzymes needed for cell growth. 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 veliparib together with capecitabine and oxaliplatin may kill more tumor cells.
The purpose of this study is to determine if a new drug, RO4929097, can work with cetuximab, a drug already approved for colorectal cancer, to help fight the patient's cancer. Cancers arise as a result of abnormal control of gene expression. One of the pathways that gets abnormally regulated in some cancers is the Notch pathway. RO4929097 is an investigational drug that blocks the activation of the Notch pathway. It is hoped that by blocking this abnormal activation, this drug may be helpful in patients with cancer but the investigators do not yet know if that is true. Cetuximab is an antibody against epidermal growth factor receptor and is known to have activity in metastatic colorectal cancer. Recent studies have shown that people with colorectal cancers that contain a mutation in a gene called K-ras do not benefit from receiving cetuximab. It is unknown if adding RO4929097 to cetuximab would benefit patients who have tumors with this mutation.
