Active clinical trials for "Colorectal Neoplasms"

The purpose of the study is to compare the efficacy of device assisted colonoscopy (DAC) with standard colonoscopy (SC) in detecting adenomas in a randomized fashion.

Basing on the strong evidence from former researches, patients with CRLM can benefit from the treatment of bevacizumab combined with sencond-line chemotherapy. Recently, although with the popularization of RFA, the role that RFA plays in the long term survival of patients with metastatic colorectal cancer (CRC) is still confused. In this designed, randomized, controlled, prospective, and open clinical trial, the effectiveness of RFA combined with second-line chemotherapy + bevacizumab on unresectable CRLM is going to be evaluated compared with that of second-line chemotherapy + bevacizumab. After screened by inclusion and exclusion criteria, the eligible subjects will be randomly allocated into the experimental group-with the treatment of RFA + second-line chemotherapy + bevacizumab and control group-with the treatment of second-line chemotherapy + bevacizumab equally.

Patients with Stage IV obstructing colorectal cancer and unresectable liver metastses, with general and local conditions not a risk for coliorectal resection, will be randomized to have either endoscopic stenting or colorectal resection

Colorectal cancer will be resistant to Chemotherapy drugs after treated for a period of time .In the past, the classical treatment regiment was to change other drug after tumor progressed. In theory, the continuous use of such a drug could shortening the patient's drug resistance time. It has been shown that the alternate use of the two drug combinations is reasonable in clinical. This application can not only further improve the curative effect but also significantly reduce the side effects. So the investigators are going to carry out a prospective phase II clinical study. The control group change to second-line treatment after progression of first-line drugs. The experimental group use the first line and the second line,alternately, for every two cycles. The combination of bevacizumab is a first line development, and the second line can still be used .Objective to compare the clinical value of XELOX and XELIRI alternation regimen in the first-line treatment of advanced colorectal cancer.

This is a single-arm, open-label, single-center prospective phase II study to evaluate the efficacy and safety of rechallenge chemotherapy in the third or later-line treatment in patients with advanced colorectal cancer. The primary end point is progression free survival (PFS). A total of 42 patients who failed with oxaliplatin, irinotecan and fluorouracil in previous treatment and could not receive the target therapy presently are planned for recruitment. For patients with metastatic colorectal cancer who met admission criteria, oxaliplatin- or irinotecan-based chemo regimen could be used and evaluation was repeated every 6 weeks. The treatment continues until the disease progression or the untolerable adverse reaction.

The purpose of the study is to evaluate if the exposure to all the three active cytotoxic agents (FOLFOXIRI regimen) is superior in terms of progression-free survival to conventional chemotherapy with the FOLFOX regimen as first-line treatment of chemo-naive metastatic colorectal cancer patients. A second primary aim is to evaluate the response rate, safety and tolerability of the chemotherapy of FOLFOXIRI regimen in this patient population. Patients will be randomized to two therapy groups: Experimental arm A: Chemotherapy with FOLFOXIRI Standard arm B: Chemotherapy with FOLFOX

This adaptive seamless Phase II/III trial is to compare the efficacy and safety of adjuvant systemic chemotherapy (SCT) with or without hepatic arterial infusion (HAI) after complete hepatic resection for Chinese patients with metastatic colorectal cancer.

Primary Objective: Correlation of the skin and/or eye toxicity grade secondary to Cetuximab or Panitumumab and the SNP profile of the Epidermal Growth Factor Receptor (EGFR) domain III region. Secondary Objectives: Correlation of SNP profile with indicators of tumour response parameters, such as radiological response, duration of response, time to progression (TTP), overall survival (OS) time, incidence of non-dermatological adverse events.

A multi-center, non-random, open study ,to observe efficacy and safety of bevacizumab plus Oxaliplatin based multidrug chemotherapy as conversion therapy for patients with previously untreated unresectable liver metastases from colorectal cancer.

The use of colonic stenting with elective surgery has been suggested as an alternative management for acute malignant colonic obstruction, as emergency surgery has a high risk of morbidity and mortality. However, the available body of literature addressing their benefit in this setting is contradictory. The purpose of this study is to determine the efficacy and safety of colonic stenting with elective surgery versus emergency surgery in the management of acute malignant colonic obstruction.
