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 evaluate the early clinical outcome of the short-course preoperative chemoradiotherapy, 33Gy/10 fx and delayed operation after chemoradiation, the investigators initiated the clinical trial of KROG 11-02.
This study will determine the following: the response rate (including pathological CR rate), TTP, and complications of treatment in patients with rectal cancer treated with FOLFOX bevacizumab, the alteration of tumor blood flow (assessed by DCE-MRI as percentage change in Ktrans) after 1 cycle of bevacizumab therapy compared to baseline value in patients treated with FOLFOX alone and those treated with bevacizumab at 5 mg/kg., the degree of hypoxis (measured by tumor uptake of the 2-nitroimidazole EF5) induced by bevacizumab treatment and its relationship to changes in tumor blood flow, and the degree of apoptosis (measured by tumor uptake of di-annexin V) induced by bevacizumab treatment and its relationship to changes in tumor blood flow.
Bowel removal is indicated for various types of colon and rectal disease, including colon cancer, rectal cancer, diverticulitis, and inflammatory bowel disease among others. Following removal of the diseased segment of bowel your surgeon will reconnect the two healthy ends to reconstruct a continuous bowel tube. If the bowel leaks it can become an extremely dangerous situation. The cause of leakage has many causes and is not well understood, but appears to be at least in part due to not having enough blood going to the bowel. There is currently no way to evaluate the blood supply to the bowel. The purpose of this study is to utilize a special camera to evaluate the blood supply of the bowel. This new system is called the Spy-scope. This system may assist surgeons in reducing the occurrence of leaks
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.
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 pilot clinical trial studies cholecalciferol in treating patients with colorectal cancer. The use of cholecalciferol may slow disease progression in patients with colorectal cancer.
The purpose of this study is to determine whether an optimal dose of [6R] 5,10-methylenetetrahydrofolate (arfolitixorin) in combination with pemetrexed are effective in pre-operative treatment of patients with resectable rectal cancer.
The aim of the study CGD-01/2000 was to investigate wheter a transverse coloplasty pouch is able to improve functional results and quality of life after coloanal anastomosis.
In this phase I trial neoadjuvant CCRT combining IMRT with three escalated dose levels (45 Gy, 50 Gy, and 55 Gy in 25 fractions) and BV-fluorouracil/ leucovorin/oxaliplatin (FOLFOX) regimens is planned for 15 locally advanced rectal cancer patients. The primary goal is to define the maximally tolerated dose of radiotherapy and the treatment related acute toxicity, and to demonstrate that preoperative highly conformal IMRT and concurrent BV-chemotherapy will lead to acceptable acute gastrointestinal morbidity. The secondary goal is to demonstrate that this treatment modality will elicit a comparable or improved rate of T stage downstaging and complete response pathologically.
