Active clinical trials for "Gastrointestinal Neoplasms"

This study will attempt to determine the feasibility of combination of Oxaliplatin, Irinotecan, and S-1, the maximum tolerated dose and the recommended doses of the agents used, and to preliminarily evaluate the antitumor activity in untreated patients with advanced gastrointestinal cancer.

The underlying hypothesis of the synergistic activity of octreotide and everolimus is based on the combination of a) a direct action of everolimus over mTOR (mammalian target of rapamycin), and b) the inhibitory effect of octreotide on the IGF-I (insulin like growth factor 1) system preventing the activation of the mTOR system by this factor. Both types of inhibition would completely cancel this signal transduction pathway, which is so important in neuroendocrine tumours. Furthermore, the biological study proposed in this protocol will allow for better establishing the relationship between the activation of the IGFR-PI3K-mTOR signal transduction pathway (i.e., the mTOR pathway stimulated by IGFR) and treatment response; this information is relevant since the IGFR-PI3K-mTOR activation status could be a response prediction factor. This study will provide significant additional information about the efficacy of the combination treatment of everolimus with octreotide LAR® in non-functioning GI NET.

RATIONALE: Radiolabeled octreotide can locate tumor cells and deliver radioactive tumor-killing substances to them without harming normal cells. PURPOSE: This phase I trial is to study the safety and effectiveness of radiolabeled octreotide in treating children who have advanced or refractory solid tumors.

RATIONALE: Drugs used in chemotherapy use different ways to stop tumor cells from dividing so they stop growing or die. PURPOSE: Phase II trial to study the effectiveness of PS-341 in treating patients who have metastatic neuroendocrine tumors.

This phase I trial is studying the side effects and best dose of giving 7-hydroxystaurosporine together with irinotecan hydrochloride in treating patients with metastatic or unresectable solid tumors, including triple-negative breast cancer (currently enrolling only patients with triple-negative breast cancer since 6/8/2007). Drugs used in chemotherapy use different ways to stop tumor cells from dividing so they stop growing or die. Giving 7-hydroxystaurosporine together with irinotecan hydrochloride may help kill more cancer cells by making tumor cells more sensitive to the drug.

This clinical trial is studying the amount of EF5 and motexafin lutetium present in tumor cells and/or normal tissues of patients with abdominal (such as ovarian, colon, or stomach cancer) or non-small cell lung cancer. EF5 may be effective in measuring oxygen in tumor tissue. Photosensitizing drugs such as motexafin lutetium are absorbed by tumor cells and, when exposed to light, become active and kill the tumor cells. Knowing the level of oxygen in tumor tissue and the level of motexafin lutetium absorbed by tumors and normal tissue may help predict the effectiveness of anticancer therapy

Patients will be randomized to early PN group or late PN group at day 3 after abdominal surgery. Patients will receive supplemental parenteral nutrition or not within 7 days after abdominal surgery. Both groups will receive SPN except 80% of target energy delivered by EN or oral or patients are discharged from hospital. The primary and secondary outcomes will be collected.

The aim of this study was to define the maximum tolerated dose (MTD) of bolus mitomycin C (MMC) in combination with 24 h-continuous infusion of 5-fluorouracil (FU) plus folinic acid, and to assess the toxicity and activity in patients with previously treated colorectal and gastric cancer. Escalating doses of MMC starting from 6 mg m(-2) in 2 mg m(-2)-steps to a maximum of 10 mg m(-2) were applied on days 1 and 22, given to fixed doses of 5-FU (2.600 mg m(-2)) as 24 h infusion and folinic acid 500 mg m(-2) prior to 5-FU weekly for 6 weeks

The PREEMPT CRC study is a prospective multi-center observational study to validate a blood-based test for the early detection of colorectal cancer by collecting blood samples from average-risk participants who will undergo a routine screening colonoscopy.

The goal of this observational population-based cohort study is to investigate the clinical characteristics and outcomes of children and adolescents with primary gastrointestinal malignancies registered in the publicly available Surveillance, Epidemiology, and End Results (SEER) 17 database during 2000-2019.
