Active clinical trials for "Stomach Neoplasms"

It is expected that RAD001 works in gastric cancer by inhibiting PI3K/AKT/mTOR pathway and Hif1A (hypoxia inducible factor 1, alpha subunit), a key player in angiogenesis and the growth of tumors like renal cell carcinoma.However, RAD001 alone looks not enough to control gastric cancer. By the mechanisms above, RAD001 can show additive or synergistic effect in combination with conventional chemotherapy. In this study, XELOX was selected as a conventional combination chemotherapy because it was proven very active and safe in gastric cancer. Combination of XELOX and RAD001 has been never tried for the treatment of cancer patients yet. So, the optimal dose will be first determined in this phase I study

The purpose of this study was to determine whether ixabepilone is effective in the treatment of unresectable or metastatic gastric cancer in Asian participants.

The purpose of this study is to assess objective tumor response in the single agent treatment of PEP02, irinotecan, or docetaxel for locally advanced or metastatic gastric or gastroesophageal junction adenocarcinoma

Background: Gastric (stomach) cancer is a rare cancer. In most cases, by the time it has been diagnosed it has spread to other organs in the body and the chance of a cure is very small. The standard treatment for gastric cancer is a combination of chemotherapy drugs. Researchers are interested in finding out if surgically removing all tumors before beginning chemotherapy for stomach cancer can slow or halt its spread better than giving chemotherapy alone. Objectives: - To determine whether tumor removal surgery followed by chemotherapy is more effective in treating gastric cancer than chemotherapy given alone. Eligibility: - Patients 18 years of age and older who have been diagnosed with gastric cancer. Design: All patients will undergo an initial physical examination, blood tests, imaging scans, and a laparoscopy to determine the extent of the disease. Half of the participants will be assigned to have surgery first and then chemotherapy; the other half will be assigned to have chemotherapy alone. The surgery-plus-chemotherapy group will have major surgery to remove all tumors in the stomach and abdominal area, followed by a recovery time of up to 4 weeks. Chemotherapy will begin 6 to 8 weeks after surgery. The chemotherapy-only group will begin treatment within 2 weeks of laparoscopy. All patients will receive four chemotherapy drugs: 5-Fluorouracil, leucovorin, oxaliplatin, and irinotecan. The drugs are given intravenously over 2 days every 2 weeks (one cycle) for 12 cycles (about 6 months), either at the National Institutes of Health (NIH) Clinical Center or at home with a referring oncologist. Patients in the surgery group who have tumors in the peritoneum will receive an additional set of chemotherapy drugs in a separate treatment. During the chemotherapy cycles, patients will provide blood samples approximately once a week and will have physical examinations and scans on a regular basis. Patients will return to the NIH Clinical Center for follow-up visits about every 4 months for 2 years, then every 6 months for 3 years and yearly thereafter.

RATIONALE: A stop-smoking plan that includes health education counseling and bupropion may help African-American smokers stop smoking. It is not yet known whether health education counseling is more effective with or without bupropion in helping African Americans stop smoking. PURPOSE: This clinical trial is studying health education counseling and bupropion to see how well they work compared with a placebo and health education counseling in helping African Americans smokers stop smoking.

In this trial, FLOT will be evaluated as therapy option for elderly patients (>65 years) with advanced gastric cancer in comparison to the well established FLO scheme. The hypothesis is that FLOT is more effective than FLO in elderly patients with acceptable side effects.

The purpose of this study is to evaluate the safety and time to progression of HLA-A*2402 restricted epitope peptides URLC10, KOC1, VEGFR1 and VEGFR2 emulsified with Montanide ISA 51.

The study consisted of two parts. In Part 1 the study enrolled 38 patients (Step 1 Simon 2 step design) after which Step 2 was opened and the total enrollment target for the study (n=63) was exceeded due to a rapid enrollment (78 patients were entered). Part 2 of the study did not open due to the final overall insufficiency of efficacy observed in 78 patients. Sunitinib (SU011248) was administered orally daily for 4 weeks followed by a 2-week rest at a starting dose of 50 mg with provision for dose reduction based on tolerability. All patients received repeated cycles of sunitinib until disease progression, occurrence of unacceptable toxicity, or other withdrawal criteria were met. After discontinuation of treatment, patients were followed up in order to collect information on further antineoplastic therapy and survival.

Primary: To demonstrate that capecitabine/oxaliplatin as adjuvant chemotherapy is superior to observation alone in terms of 3 year disease-free survival (DFS) rate in chemotherapy-naïve patients who underwent potentially curative resection for gastric cancer. Secondary: To compare the overall survival of surgery and capecitabine/ oxaliplatin as adjuvant therapy versus surgery alone. To evaluate the safety profile of capecitabine/oxaliplatin adjuvant therapy.

The combination of capecitabine and oxaliplatin as 'backbone' regimen, adding a newer biologic agent, cetuximab, is a reasonable strategy of further chemotherapy development in advanced gastric cancer, which is the investigators study rationale.
