Active clinical trials for "Colorectal Neoplasms"

The primary objective was to describe the pattern of use of panitumumab (Vectibix®) in combination with chemotherapy in patients with wild-type rat sarcoma viral oncogene homolog (RAS) metastatic colorectal cancer (mCRC): as first-line treatment in combination with FOLFOX or FOLFIRI or second-line treatment in combination with FOLFIRI in patients who have received first-line fluoropyrimidine-based chemotherapy (excluding irinotecan).

Objective: To test the sensitivity of a proprietary novel filtration device designed to capture and concentrate circulating tumor cells (CTCs).

Prometheus's Onco dX assay platform provides technological breakthrough for immunoassay by obtaining a level of sensitivity down to single tumor cells without compromising specificity. This allows assessment of multiple TKI treatment targets, their activation status, as well as down stream signaling proteins using very tiny amount of tissue that can be obtained by FNA or CTCs. We planned this study to explore biomarkers predictive of clinical response to cetuximab-based treatment in metastatic colorectal cancer using the Prometheus Platform. We will also elucidate signal transduction pathway attributable to cetuximab resistance, monitor changes in the RTK activation status during cetuximab treatment using circulating tumor cells and analyze correlation between the quantity of circulating tumor cells and treatment response to cetuximab.

Detect plasma Hsp90α concentration of colorectal cancer patients, healthy volunteers, benign colorectal diseases patients.

The purpose of this study is to see whether gene mutations can be found in the urine or blood of lung cancer patients and urine of colorectal cancer patients. Gene mutations are when DNA in a gene is damaged in a way that changes the genetic message carried by that gene. Gene mutations can sometimes cause lung cancers. These gene mutations are only found in lung and colorectal cancer cells, not the normal cells in your body. All lung cancer tumors and colorectal cancer tumors are now tested for different gene mutations as their presence affects lung cancer treatment. Tumor samples obtained from a biopsy or surgery are typically tested for these gene mutations.

The purpose of this study is to determine whether colorectal cancer diagnosed by screening (primary screening colonoscopy, colonoscopy after immunochemical based faecal occult blood test) has more favourable clinical-pathological characteristics than colorectal cancer diagnosed for symptoms. We aimed to compare these two groups of patients at the time of diagnosis and confirm the efficiency of the screening programme.

The objective of the program is to provide access to TAS-102 to patients with metastatic colorectal cancer who are refractory to or failing standard chemotherapy, are new to therapy with TAS-102 and in whom therapy with TAS-102 is clinically indicated.

Sox2 has been studied in several types of human solid tumors. The investigators found that Sox2 had higher expression level in colorectal cancer and metastatic tissues than normal tissues. So the investigators assumed that whether Sox2 plays an important role in the progression and migration of colon cancer.

The purpose of this registry is to collect information about patients in which a pouch has been created to improve in the future the quality of the surgery of the pouch.

The aim of this sudy is to investigate the prevalence of colorectal cancer (CRC) in patients with nonalcoholic fatty liver disease (NAFLD) and evaluate whether NAFLD is a risk factor for CRC.
