Filter by:The purpose of this study is to monitor the success rates and completion rates for endoscopic submucosal dissection (ESD) for gastrointestinal (GI) cancers.
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.
The investigators hypothesize IXO chemotherapy will have an improvement in response rate and acceptable toxicity for uncurable metastatic gastric cancer compared to historical controls.
Octreotide (OCT) is a somatostatin analogue (SSA) available in a long-acting formulation, conventionally administered every 28 days at the maximum dose of 30 mg. Together with lanreotide, it is considered the therapy of choice in the control of endocrine syndromes associated with neuroendocrine tumors (NET)s. A complete or partial clinical response to SSA therapy is generally achieved in at least 50% of the patients with neuroendocrine syndrome. Many studies reported a clinical response in 70-90% of functioning NETs. In about 36-50% of the patients with progressive advanced well differentiated NET (WDNET), a stabilization of disease occurs after treatment with subcutaneous OCT. By developing long-acting slow-release SSA formulation, long-acting OCT (LAR), lanreotide-SR, lanreotide-Autogel, the patient's compliance to SSA therapy was improved and escape from treatment, which was common with the subcutaneous formulation, was avoided. However, rate of objective response was not significantly improved as compared to short-acting SSA. On the other hand, it has to be remarked that long-acting SSA are being used in NET patients at doses correspondent to the low doses of short-acting formulation. The higher commercially available doses of LAR is 30 mg, which is assumed to be comparable to 300 µg of short-acting OCT in the therapy of acromegaly. Only one study was designed to investigate the use of high-dose LAR (160 mg every 28 days). In this study, objective and hormonal responses in patients with progressive metastatic ileal NET non-responder to standard doses, was significantly elevated. However, this compound has never been commercialized and, of consequence, this first preliminary observation has not been confirmed by further studies. No systematic studies were performed with the commercially available long-acting SSA used in high-dose treatments. In patients with progressive locally advanced or metastatic NET, increase of the dose or reduction of the interval between injections is a relatively common "empirical" clinical practice, but no studies have been performed to evaluate safety and efficacy of this treatment schedule.
The aim of the study is to determine wether subcutaneus suction drain (type redon-drain) protect against surgical side infection by laparotomy in general surgery.
To investigate safety and efficacy of single agent sunitinib malate in Chinese Patients With Imatinib Resistant Or Intolerant Malignant Gastrointestinal Stromal Tumor.
This clinical study is being conducted at multiple sites to determine the best confirmed response rate, safety, and tolerability of GSK1363089 treatment in metastatic gastric carcinoma.
The purpose of the study is to collect pancreatic tissue, blood and urine from adults to study pancreatic abnormalities.
The purpose of this study is to evaluate the clinical benefit of the KIT inhibitor XL820 in subjects with advanced gastrointestinal stromal tumors (GIST) who are resistant to or intolerant of Imatinib and/or Sunitinib.
The study will determine if changes in expression of markers involved in the 5-FU pathways are associated with response to treatment with the combination of lapatinib and capecitabine independent of tumor erbB2 status.
