Active clinical trials for "Stomach Neoplasms"

This is a phase III randomized study designed to evaluate the efficacy of mitomycin, doxifluridine, and cisplatin compared to mitomycin and doxifluridine.

A significant proportion of advanced gastric cancer (AGC) occurs in individuals 65 years of age and older. In addition, patient delay in seeking care for symptoms results in diagnosis at a more advanced stage than that seen in younger individuals. However, clinical trials on gastric cancer rarely have been available to the elderly. Recently oral 5-FU pro-drugs, which have been reported to have clinically significant response rates and survival with mild or negligible toxicities, have been widely used for the patients with AGC. However, few studies have been conducted in elderly patients.

RATIONALE: Stop-smoking plans, including counseling and nicotine replacement therapy, may help smokers quit smoking. It is not yet known whether counseling and the nicotine lozenge is more effective than counseling and the nicotine patch in helping adult smokers quit smoking. PURPOSE: This randomized phase III trial is studying counseling and the nicotine lozenge to see how well they work compared to counseling and the nicotine patch in helping smokers quit smoking.

This phase II trial is studying how well giving irinotecan and cisplatin together with bevacizumab works in treating patients with unresectable or metastatic gastric (stomach) or gastroesophageal junction adenocarcinoma (cancer). Drugs used in chemotherapy, such as irinotecan and cisplatin, work in different ways to stop tumor cells from dividing so they stop growing or die. Monoclonal antibodies such as bevacizumab can locate tumor cells and either kill them or deliver tumor-killing substances to them without harming normal cells. Giving chemotherapy together with a monoclonal antibody may kill more tumor cells.

This will be an international, multicenter, uncontrolled, 2-stage, phase II study in adult patients with advanced gastric cancer, reasonable performance status, good organ function, lack of serious concomitant medical conditions. Patients must have progressed or recurred after a fluoropyrimidine-containing regimen at anytime for primary metastatic disease or within 6 months of last dose of adjuvant therapy. Twenty-one evaluable patients will be enrolled in Stage 1. If at least 2 objective tumor responses are observed in the first 21 evaluable patients, the study will be expanded to enroll a total of 41 evaluable patients. Edotecarin will be administered at a starting dose of 13 mg/m2 as an IV infusion over 60 minutes in repeated 3-week cycles treatment.

RATIONALE: Drugs used in chemotherapy work in different ways to stop tumor cells from dividing so they stop growing or die. PURPOSE: Phase II trial to study the effectiveness of T900607 in treating patients who have gastroesophageal junction cancer.

RATIONALE: Bortezomib may stop the growth of tumor cells by blocking the enzymes necessary for their growth. PURPOSE: Phase II trial to study the effectiveness of bortezomib in treating patients who have unresectable or metastatic gastric cancer or gastroesophageal junction adenocarcinoma.

Imatinib mesylate may stop the growth of tumor cells by blocking the enzymes necessary for tumor cell growth. This phase II trial is studying how well imatinib mesylate works in treating patients with refractory metastatic and/or unresectable stomach or gastroesophageal junction cancer.

This study aimed to verify the survival benefit of TS-1 plus CDDP combination chemotherapy compared with the monotherapy by TS-1 alone.

Because well-designed, randomized, controlled clinical trials are lacking in patients with advanced gastric cancer (AGC), and because randomly allocating patients to treatments that do not accord with their preferences may influence trial validity, the investigators employed a patient preference randomized trial design to compare the efficacy of second-line chemotherapy and best supportive care.
