Active clinical trials for "Stomach Neoplasms"

RATIONALE: Analgesics, antiemetics, steroids, and radiation therapy are effective in helping to control symptoms caused by cancer. It is not yet known whether these treatments are more effective when given with or without docetaxel in treating patients with relapsed esophageal cancer or stomach cancer. PURPOSE: This randomized phase II trial is studying symptom control given together with docetaxel to see how well it works compared with symptom control given without docetaxel in treating patients with relapsed esophageal cancer or stomach cancer.

This randomized phase II trial studies combination chemotherapy when given together with vismodegib to see how well it works compared with combination chemotherapy without vismodegib in treating patients with advanced stomach cancer or gastroesophageal junction cancer. Drugs used in chemotherapy, such as oxaliplatin, leucovorin calcium, and fluorouracil, work in different ways to stop the growth of tumor cells, either by killing the cells, by stopping them from dividing, or by stopping them from spreading. Giving more than one drug (combination chemotherapy) may kill more tumor cells. Vismodegib may stop the growth of stomach or gastroesophageal junction cancer by blocking the growth of new blood vessels necessary for tumor growth. It is not yet known whether combination chemotherapy is more effective when given with or without vismodegib in treating stomach cancer and gastroesophageal junction cancer.

This randomized phase II trial studies how well giving irinotecan hydrochloride with or without alvocidib works in treating patients with advanced stomach or gastroesophageal junction cancer that cannot be removed by surgery. Drugs used in chemotherapy, such as irinotecan hydrochloride, work in different ways to stop the growth of tumor cells, either by killing the cells or by stopping them from dividing. Alvocidib may stop the growth of tumor cells by blocking some of the enzymes needed for cell growth. It is not yet known whether irinotecan hydrochloride is more effective with or without alvocidib.

The objectives of this study are to evaluate the anti-tumor activity, safety, and tolerability of telatinib when used in combination with chemotherapy (capecitabine and cisplatin) as first-line therapy in subjects with advanced gastric cancer. The primary objective is to assess progression free survival (PFS) in subjects receiving telatinib in combination with chemotherapy (capecitabine and cisplatin). The secondary objectives are to assess overall survival, overall response rate, safety and tolerability, pharmacokinetics and biomarkers.

The purpose of this study is to determine the maximum tolerated dose (MTD) of BMS-833923 administered in combination with Cisplatin and Capecitabine as first-line therapy in subjects with inoperable metastatic gastric, gastroesophageal or esophageal adenocarcinomas.

The purpose of this study is to determine the safe and tolerable dose of sunitinib when given together with cisplatin and 5-fluorouracil in patients with advanced gastric cancer who have not received prior chemotherapy for their advanced cancer.

This study intends to evaluate the feasibility and treatment efficacy of adding an antibody blocking the epidermal growth factor (EGF) pathway to a neoadjuvant approach with proven efficacy developed at New York University.

The purpose of this study is to gather information about the use of an investigational drug called Ramucirumab in adenocarcinomas of the stomach or gastroesophageal junction.

This study is to evaluate the efficacy and safety of addition of intraperitoneal (ip) Floxuridine to adjuvant chemoradiation therapy for patients under-going potentially curative stomach resection.

Thymidylate Synthase (TS) is a key enzyme in the synthesis of DNA and the target enzyme inhibited by 5-fluorouracil (5-FU). TS level in the tumour cells has been reported as predictive to response to 5-FU and a prognostic factor in colorectal and gastric cancer patients. We plan to study TS by immunohistochemistry (IHC) in the paraffin blocks of tumour tissue. A combined comparative genomic hybridization (CGH) and expression microarray analysis of gastric cancer specimens before and after neoadjuvant chemotherapy. CGH will be performed using standard technique routinely done in Dr Patrick Tan's laboratory at the National Cancer Centre, which determines the gain or loss of DNA copies of each chromosome. Total RNA will be extracted from at least one biopsy sample which contains at least 50% cancer cells by homogenization of the tumour tissue and tri-sol method. 5 ug of RNA were amplified and hybridized with the C-DNA microarrays of 18K targets. Primary Objective 1. Feasibility and safety of pre-operative chemotherapy in locally advanced gastric cancer. Secondary Objective Complete clinical and pathological response rates to pre-operative chemotherapy in locally advanced gastric cancer Complete resection rate. Time to recurrence, disease free and overall survival Correlation of clinical outcome with (Runt-related transcription factor) RUNX-3 methylation status and Thymidylate synthetase in the tumor tissue. Correlation of CGH and gene expression profile and their changes after chemotherapy with clinical outcome. Patients may be included in the study only if they meet all of the following criteria: Age at least 18 years. Histologic or cytologic diagnosis of adenocarcinoma of stomach or gastric cardia (Siewert Classification Type III) Preoperative Stage T3-4NxM0 by endoscopic ultrasound, CT of the abdomen/pelvis and laparoscopy. (CT of the chest if it is a cardia lesion). Absence of malignant cells in peritoneal lavage fluid during laparoscopic examination. Patients must not have received any prior chemotherapy or hormonal therapy for the treatment of gastric cancer. Karnofsky performance status of 70 or higher. Estimated life expectancy of at least 12 weeks. Adequate organ function including the following: - Bone marrow: White blood cells (WBC) at least 3.5 x 109/L Absolute neutrophil (segmented and bands) count (ANC) at least 1.5 x 109/L Platelets at least 100 x 109/L Haemoglobin at least 9g/dL - Hepatic: Bilirubin within upper limit of normal (ULN), Aspartate transaminase (ALT) or Alanine transaminase (AST) not more than 2.5x ULN Alkaline phosphatase not more than 2.5x ULN. - Renal: creatinine not more than 1.5x ULN Signed informed consent by patient or legal representative. Patients with reproductive potential must use an approved contraceptive method if appropriate (eg, intrauterine device, birth control pills, or barrier device) during and for three months after the study. Females with childbearing potential must have a negative serum pregnancy test within 7 days prior to study enrollment. The study plans to recruit 30 patients in 12-18 months.
