Filter by:The aim of this study is to determine whether greater rectal cancer downstaging and regression occurs when surgery is delayed to 12 weeks after completion of radiotherapy/chemotherapy compared to 6 weeks. Hypothesis: Greater downstaging and tumour regression is observed when surgery is delayed to 12 weeks after completion of CRT compared to 6 weeks.
RATIONALE: Drugs used in chemotherapy, such as doxorubicin, work in different ways to stop the growth of tumor cells, either by killing the cells or by stopping them from dividing. Infusing doxorubicin beads into the liver, and blocking blood flow to the tumor, may keep doxorubicin near the tumor and kill more tumor cells. PURPOSE: This clinical trial is studying the side effects of doxorubicin beads and to see how well they work in treating patients with unresectable liver metastases from neuroendocrine tumors.
The proposal seeks to establish: - A comprehensive compilation (database) of clinical information comprising clinical, histopathological, treatment and follow-up characteristics of past and future gastrointestinal cancer (GIC) cases in Singapore that can be shared by investigators. The characteristics will include clinical (eg age, sex, stage), histopathological (eg. grade, type), treatment (eg. treatment status, regimens) and outcome data (eg. survival, toxicity) from medical records. - A collection (bank) of corresponding frozen and fixed tissue, blood and processed samples (enriched blood mononuclear cells, protein, RNA, DNA, tissue arrays) in Singapore that can be shared by the investigators. - A gastrointestinal cancer co-operative group (GCCG) of clinicians and scientists researching prognostic and predictive markers in GIC, which will benefit from the multi-disciplinary knowledge, information and samples of its members. - To characterise genetic polymorphisms related to Gastrointestinal cancer chemotherapy treatment in controls (healthy volunteers)
RATIONALE: Screening tests may identify people with cancer who are at high risk of losing weight and help doctors plan better treatment. PURPOSE: This clinical trial is studying how well a new screening tool works in predicting weight loss in patients with cancer.
This is an international multi-center trial that will enroll patients with locally advanced, unresectable, or metastatic gastric, esophageal, or gastro-esophageal junction cancer whose tumors have amplification of the ErbB2 (HER2) gene. The trial will investigate whether lapatinib, when added to the chemotherapy regimen, capecitabine plus oxaliplatin (CapeOx), extends the time to progression and overall survival. Tumor ErbB2 (HER2) status must be known before trial entry. CapeOx is administered to all patients, and patients will be randomly assigned to receive either lapatinib or placebo.
RATIONALE: Questionnaires that measure quality of life may help doctors identify the effects of treatment and improve the ability to plan treatment for patients with gastrointestinal-related neuroendocrine tumors. PURPOSE: This phase IV clinical trial is studying how well a disease-specific questionnaire works in assessing the quality of life of patients with gastrointestinal-related neuroendocrine tumors.
RATIONALE: Nelfinavir may stop the growth of tumor cells by blocking some of the enzymes needed for cell growth. PURPOSE: This phase I trial is studying the side effects and best dose of nelfinavir in treating patients with metastatic, refractory, or recurrent solid tumors.
