Filter by:The main objectives of this study are to determine the maximum tolerated dose (MTD) and recommend dose (RD) of Oraxol® in Phase I and to determine the objective response rate of Oraxol® in Phase II.
S-1 is an effective drug in gastric cancer (GC) for palliative chemotherapy in Eastern and Western patients. Recently, S-1 has been also reported to be an effective adjuvant therapy for GC patients who received D2 surgery in Eastern Asian patients. Recently, the development of lacrimal drainage obstruction (LDO) caused by S-1 has been reported from some case and small-sized studies. The incidence of developing LDO has been estimated to about 15~20% of patients receiving S-1 therapy in some retrospective studies. However, there is no prospective report on the incidence of LDO in patients receiving S-1 chemotherapy. Moreover, the mechanism of developing S-1-induced LDO has not been systemically studied until now. Suggested mechanism of LDO involves direct secretion of S-1 into the tear. Therefore, this study was initiated to prospectively investigate the incidence of LDO in GC patients receiving adjuvant S-1 chemotherapy. In addition, the correlation between the development of LDO and the concentration of S-1 (or its metabolites) in tear and plasma will be explored. These results will help clinicians identify patients who are at high risk of developing S-1-associated LDO.
This is a phase II study to evaluate RAD001 (Everolimus) in terms of 4-month progression-free survival rate (primary end-point) and response rate, toxicity, overall survival and biomarker assessment (secondary end-points) in patients with metastatic or recurrent gastric cancer with pS6 Ser 240/4 expression. Eligibility criteria include pathologically proven non-resectable adenocarcinoma of stomach with measurable disease who failed previous first-line palliative chemotherapy including fluoropyrimidine and platinum with high expression of pS6 Ser 240/4. Oral RAD001 (everolimus) 10mg daily will be administered and the dose will be adjusted according to the observed clinical toxicities. Treatment will be continued until disease progression or patient's intolerability to the study drug. A study requires 40 assessable subjects to decide whether the proportion of patients who are free from progression at 4 months (16 weeks), P, is less than or equal to 0.1 or greater than or equal to 0.25 with a target error rate of 0.05 and β of 0.2. If the number of responses is 7 or less, the hypothesis that P >= 0.250 is rejected with a target error rate of 0.200 and an actual error rate of 0.182. If the investigators assume that drop-out rate is 10%, total accrual patient will be 45.
A Japanese study showed that the additional use of an "Extensive Intraperitoneal Lavage" (EIPL), i.e. an extensive washing of the abdominal cavity with water, during surgery for gastric cancer can lead to a significant increase in survival. However, the study was confined to patients in whom upon commencing surgery, free peritoneal tumor cells were detected, which is only a small fraction of patients. The primary objective of our study is to assess in all patients undergoing removal of the stomach and adjacent lymph nodes for stomach cancer, if EIPL can eliminate free peritoneal tumor cells which have been present at the beginning of the surgery or after the stomach and lymph node removal. Secondary objectives are to assess how often free peritoneal tumor cells occur in patients with stomach cancer, how often surgical resection itself leads to a release of tumor cells, the safety of the EIPL procedure, and disease-free and overall survival of patients undergoing EIPL. Based on the outcome of this japanese study we want to test with special laboratory methods why this lavage leads to a better outcome. Specifically, the trial will test the hypotheses that a) lymph node dissection causes a release of tumor cells in the abdominal cavity, and b) EIPL eliminates free peritoneal tumor cells.
This is a multi-center, prospective and observational clinical study. Eligible patients will accept generalized chemotherapy according to the investigator's assessment. Information related to the treatment, including medication, disease condition, expenses, etc. will be periodically collected. Follow-up at 2-month intervals will be periodically performed to continually collect information about the disease progression, subsequent treatment and survival until death or completion of the study. Recruited patients will fill out questionnaires about quality of life before initiation of treatment, at Cycle 3 and completion of first-line treatment.
The investigators seek to compare two techniques of removing pre-cancerous lesions from the colon. The investigators also will compare two solutions used during the procedure to determine if either solution allows for an improved removal of the tumors.
The purpose of this study is to determine whether docetaxel, capecitabine, cisplatin, and bevacizumab are effective in the treatment of unresectable advanced gastric cancer.
The recurrence and metastasis of peritoneum is always the lethal consequence for gastric cancer patients, and there is no effective therapy until now. It has been reported by Dr.Fujimoto that intraperitoneal chemotherapy plus hyperthermic therapy, which called hyperthermic intraperitoneal chemotherapy (HIPEC), can eliminate and suppress the free cancer cells and tiny metastasis in abdomen. Refer to the experience of systematic chemotherapy, HIPEC with combination regimen would have a brighter prospect. In this study, the investigators would use Oxaliplatin and paclitaxel sequent as HIPEC regimen. The safety and overall survival would be observed and evaluated.
The objective of the trial is to compare Overall survival between capecitabine plus oxaliplatin (XELOX) and capecitabine (X) as first-line chemotherapy in elderly patients with advanced gastric cancer.
To assess the role of germline polymorphisms in xenobiotic metabolism genes in toxicity profile. To assess the role of germline polymorphisms in genes associated with DNA repair, p53 tumor suppressor gene and angiogenesis pathway in predicting recurrence and survival in gastric cancer patients treated with adjuvant chemotherapy.
