Active clinical trials for "Colorectal Neoplasms"

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.

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.

The aim of this study is to compare the activity and safety of Oxaliplatin and S-1 (SOX) and Oxaliplatin and Capecitabine (XELOX) in patients with peritoneal metastasis of colorectal cancer.

This research trial studies the gut microbiome in fecal samples from patients with cancer that has spread to other parts of the body who are undergoing chemotherapy or immunotherapy. Studying samples of feces from patients with metastatic cancer in the laboratory may help doctors learn if the make-up of the gut microbiome has a positive or negative influence to a patient's response to chemotherapy or immunotherapy.

This study is a randomized phase II trial to evaluate the efficacy of adjuvant consolidative radiotherapy in colorectal cancer liver metastasis (CRLM) patients after chemotherapy combined with surgical resection or radiofrequency ablation of liver lesions.

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.

This is an Exploratory Clinical Trial Study on Apatinib in the Treatment of Metastatic Colorectal Cancer Who Have Progressed after Standard Second Line Therapy.

The purpose of this study is to evaluate the efficacy and safety of recombinant anti-EGFR Monoclonal antibody（SCT200）in patients with wild-type RAS and BRAF mCRC treated with fluorouracil, oxaliplatin and irinotecan after failure of standard therapy

A prospective, multicenter, randomized in a 2:1 ratio, controlled, clinical trial with two parallel arms will be conducted to compare irinotecan dose escalated FOLFIRI according to UGT1A1 genotyping plus 120 mg regorafenib with 120 mg regorafenib alone in previously treated patients with metastatic colorectal cancer (mCRC).

This randomized controlled clinical phase II study was designed to compare the effect of rhTPO with rhIL-11 in improving thrombocytopenia in patients with recurrent colorectal cancer who underwent radiotherapy and with thrombocytopenia.
