Active clinical trials for "Colorectal Neoplasms"

Cisplatin is a widely used anti-tumor agent for the treatment of testicular and ovarian cancers. Carboplatin is used extensively for small cell, non small cell lung cancer and ovarian cancer. Oxaliplatin has recently been approved in the United States (US) for treatment of colorectal cancer. A large portion (in the range of 65% to 98%) of cisplatin in the blood plasma was bound to protein within a day after intravenous administration. The binding of cisplatin and other analogues to proteins and enzymes is generally believed to be the cause of several severe side effects such as ototoxicity and nephrotoxicity. The interactions between platinum based chemotherapy drugs and proteins is proposed to play important roles in both drug activity and toxicity. Therefore, a better understanding of the molecular mechanism of platinum-protein interactions may have an impact on optimization of strategies for treatment. The objective is to develop novel approaches and techniques to provide detailed mechanistic, kinetic and high-resolution structural information on the binding of platinum analogues to blood proteins, and to improve treatment efficacy and reduce side effects.

The primary objective of this Phase 1 study is to identify the recommended dose of capiri and of sunitinib for combination therapy subsequent phase II trials.

It is uncertain, whether hilar lymphadenectomy should be performed routinely in patients undergoing resection of colorectal liver metastases. For this reason it is the aim of the present prospective randomized trial to evaluate, if routine lymphadenectomy reduces recurrent disease in patients undergoing resection of colorectal liver metastases.

To assess the usefulness of irinotecan plus S-1 therapy based on the antitumor effect and survival period. by performing a phase II study of this combination in patients with inoperable or with postoperative colorectal cancer.

The aim of this study is to compare the stoma rate, clinical efficacy, and safety of patients treated by endoscopic stenting followed by elective laparoscopic resection (the 'endolaparoscopic approach') versus immediate emergency surgery for obstructing left-sided colorectal cancers.

RATIONALE: Drugs used in chemotherapy work in different ways to stop the growth of tumor cells, either by killing the cells or by stopping them from dividing. Internal radiation uses radioactive material placed directly into or near a tumor to kill tumor cells. Giving chemotherapy together with internal radiation may kill more tumor cells. PURPOSE: This phase II trial is studying how well giving chemotherapy together with internal radiation works in treating patients with colorectal cancer that has spread to the liver.

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 compare the effectiveness of fluorouracil with or without mitomycin in treating patients who have peritoneal cancer.

RATIONALE: Drugs used in chemotherapy use different ways to stop tumor cells from dividing so they stop growing or die. PURPOSE: Phase I trial to study the effectiveness of tocladesine in treating patients who have recurrent or progressive metastatic colorectal cancer.

RATIONALE: Drugs used in chemotherapy use different ways to stop tumor cells from dividing so they stop growing or die. SU5416 may stop the growth of tumor cells by stopping blood flow to the tumor. It is not yet known whether combination chemotherapy will be more effective with or without SU5416 in treating metastatic colorectal cancer. PURPOSE: Randomized phase III trial to compare the effectiveness of combination chemotherapy with or without SU5416 in treating patients who have metastatic colorectal cancer.

Study to determine the feasibility of Sentinel Lymph Node (SLN) mapping using novel magnetic tracers (FerroTrace) and indocyanine green (ICG) for colorectal cancer; and to evaluate safety by assessing short term toxicity associated with colonoscopic peritumoral injection of novel magnetic nanoparticles (FerroTrace) and ICG for colorectal cancer.
