Active clinical trials for "Digestive System Neoplasms"

The purpose of this study is to investigate the safety and determine the maximum tolerated dose of TAS-102 administered in combination with CPT-11 in patients with advanced gastrointestinal tumors.

The purpose of this study is to determine maximum tolerated dose (MTD), dose limiting toxicities (DLT) and recommend a proper dose for our phase II study of S-1 when combined with radiation therapy for locally advanced or recurrent gastric cancer.

To investigate safety and efficacy of single agent sunitinib malate in Chinese Patients With Imatinib Resistant Or Intolerant Malignant Gastrointestinal Stromal Tumor.

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.

There has been no successful treatment of diffuse peritoneal metastasis or carcinomatosis, in childhood tumors. Once this advanced stage of disease is evident, survival is measured in weeks. The selective lethal effect of supranormal temperatures on neoplastic cells and the additive or synergistic effect of combining chemotherapy has been well established in adult clinical trials using continuous hyperthermic peritoneal perfusion (CHPP) for advanced peritoneal adenocarcinoma of gastrointestinal origin, ovarian carcinoma and mesothelioma. This phase I study will evaluate the safety of continuous hyperthermic peritoneal perfusion with escalating doses of intraperitoneal cisplatin in the treatment of children with refractory tumors limited to the abdominal cavity. If tumors are outside the abdominal cavity, the tumors must be able to be controlled. Since CHPP has potential to improve outcome of children with peritoneal and retroperitoneal metastases, this study will evaluate the safety of elevated temperature (40oC) with intraperitoneal cisplatin chemotherapy. Primary Objectives: To determine the MTD and dose-limiting toxicity of intraperitoneal cisplatin given in combination with CHPP as a 90 minute perfusion in children with advanced peritoneal and retroperitoneal solid tumors To determine the safe and tolerable dose of CHPP with cisplatin to be used in Phase II trials To determine the pharmacokinetics of intraperitoneal cisplatin platinum given with CHPP as a 90 minute abdominal perfusion (Optional)

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 purposes of this study are: To assess the maximum tolerated dose of low-dose UART(Upper Abdominal Radiation Therapy ) or WART(Whole Abdominal Radiation Therapy) given in combination with standard fixed dose-rate Gemcitabine in patients with advanced gastrointestinal (GI) or ovarian tumors (Phase I). To assess response rate and survival in advanced upper GI tumors following completion of therapy (Phase II).

The CRC DRAW study will assess the sensitivity and specificity of the blood-based, Next-Gen CRC Screening Test for the detection of CRC.

The study is designed to investigate the influence of parenteral nutrition (PN) with low nitrogen and calorie supply on the clinical outcome of patients after an operation compared to that of traditional PNs.
