Active clinical trials for "Colorectal Neoplasms"

RATIONALE: Biological therapies such as gefitinib may interfere with the growth of the tumor cells and slow the growth of recurrent metastatic colorectal cancer. PURPOSE: Randomized phase II trial to compare the effectiveness of two different doses of gefitinib in treating patients who have recurrent metastatic colorectal cancer.

This 4 arm study assessed the efficacy and safety of oral capecitabine (Xeloda) or intravenous (iv) fluorouracil/leucovorin, in combination with iv oxaliplatin (Eloxatin) with or without iv bevacizumab (Avastin), as a first-line treatment in patients with metastatic colorectal cancer. Patients were randomized to receive 1) XELOX (Xeloda 1000 mg/m^2 orally [po] twice a day [bid] on Days 1-15 + oxaliplatin in 3 week cycles), 2) FOLFOX-4 (oxaliplatin + leucovorin + fluorouracil [5-FU] in 2 week cycles), 3) XELOX + bevacizumab (7.5 mg iv on Day 1 in 3 week cycles), or 4) FOLFOX-4 + bevacizumab (5 mg iv on Day 1 in 2 week cycles).

This 2 arm study will assess the efficacy and safety of intermittent oral Xeloda, or iv fluorouracil/leucovorin, in combination with intravenous Eloxatin (oxaliplatin) in patients previously treated for metastatic colorectal cancer. Patients will be randomized to receive either 1)XELOX (Xeloda 1000mg/m2 po bid on days 1-15 + oxaliplatin) in 3 week cycles or 2) FOLFOX-4 (oxaliplatin + leucovorin + 5-FU in 2 week cycles. The anticipated time on study treatment is until disease progression, and the target sample size is 500+ individuals.

RATIONALE: Drugs used in chemotherapy use different ways to stop tumor cells from dividing so they stop growing or die. Combining more than one drug may kill more tumor cells. PURPOSE: Randomized phase II trial to study the effectiveness of combining fluorouracil and leucovorin with or without oxaliplatin in treating patients who have recurrent metastatic colorectal cancer.

RATIONALE: Drugs used in chemotherapy use different ways to stop tumor cells from dividing so they stop growing or die. PURPOSE: Randomized phase II trial to compare the effectiveness of two different regimens of Ro 31-7453 in treating patients who have recurrent or refractory metastatic colorectal cancer.

RATIONALE: Drugs used in chemotherapy use different ways to stop tumor cells from dividing so they stop growing or die. Ethynyluracil may help fluorouracil kill more cancer cells by making tumor cells more sensitive to the drug. PURPOSE: Phase II trial to study the effectiveness of fluorouracil plus ethynyluracil in treating patients with advanced colorectal cancer that has not responded to fluorouracil.

RATIONALE: Radiation therapy uses high energy x-rays to damage tumor cells. Drugs used in chemotherapy use different ways to stop tumor cells from dividing so they stop growing or die. Combining radiation therapy with chemotherapy may kill more tumor cells. PURPOSE: Phase I/II trial to study the effectiveness of radiation therapy plus irinotecan in treating patients with colon cancer that is recurrent or that cannot be removed surgically.

Compare the efficacy and safety of endoscopic resection a full thickness (EFTR) with Full Thickness Resection Device (FTRD) System versus endoscopic submucosal dissection (ESD) in the treatment of Laterally Spreading Tumor Non Granular Type (LST-NG), "no lift" lesions colon and residual / relapse on scars from previous resections endoscopic colon. The dimensional cut off of these lesions is ≤30mm

The aim of project EMPACOL will be to investigate, while taking into consideration the clinical factors known and well described in the literature, among the non-clinical factors, in particular, patient-healthcare personnel (HCP) relationship, a link between HCP's empathy perceived by the patient, and the results of the curative treatment of non-metastatic colorectal cancer, throughout the patient's care.

Evaluation of some risk factors (e.g. smoking, heavy metal exposure, and organophosphorus exposure) on CRC. Estimation of KRAS and BRAF genes mutations associated with CRC. Association between different risk factors and gene mutations on different types of CRC.
