Filter by:This phase II trial studies how well combination chemotherapy works in treating patients with advanced stomach, gastroesophageal, or esophageal cancer. Drugs used in chemotherapy, such as irinotecan hydrochloride, oxaliplatin, leucovorin calcium, and fluorouracil, work in different ways to stop the growth of tumor cells, either by killing the cells or by stopping them from dividing. Giving more than one drug (combination chemotherapy) may kill more tumor cells.
40 eligible patients with confirmed esophageal or gastric adenocarcinoma and anemia will be randomized to a control or intervention group for management of this anemia. The control group treatment will consist of standard treatments as governed by the clinical team (eg oral iron, blood transfusions) whilst the intervention group will be treated with intravenous iron III isomaltoside (Monofer ®). It is hypothesized that intravenous iron supplementation is more efficacious than standard therapies.
By literature review, there is a clear trend towards a potential role for human epidermal growth factor receptor 2 (HER2) as a negative prognostic factor in gastric cancer was shown, but only in half of the analyses used multivariate statistics. Besides, For the studies in the current review that have looked at the Lauren classification in relation to HER2, a higher level of overexpression or amplification was found in the intestinal phenotype compared to the diffuse or mixed types. As lauren classification was reported as an independent prognostic factor result in favored outcomes in gastric cancer (GC), there may probably be histologic bias exists when compare overall survival (OS) between HER2 statuses without controlling this confounding. Similarly, patients with different disease settings (early stage and advanced stage; resectable and metastatic) affect outcomes either. In this study, the investigators will retrospectively analyze HER2 status and lauren classification in 800 gastric patients who received gastrectomy in the Cancer Center of Sun Yat-Sen University between January 1996 and December 2006 with formalin-fixed and paraffin- embedded tumor tissue samples. To avoid potential influence by histologic classifications and disease settings, the investigators assess difference in OS between HER2 positive and HER2 negative groups in resectable Lauren classification of GCs, and further evaluate the prognostic value of HER2 status according to tumor-node-metastasis (TNM) stages.
Lymph node dissection in gastric cancer surgery is a very important factor not only for exact acquisition of stage but also proper treatment. Realistically, it is impossible to identify complete removal of lymph node in dissected nodal station by naked eye. The investigators can assess the route of lymphatic drainage and identify residual lymph nodes in dissected area. In the field of gastric cancer treatment, ICG and near infra-red fluorescence imaging was used only detection of sentinel lymph nodes. However, this novel concept can help to understand lymphatic drainage and make surgeons to perform D1+ or D2 lymph node dissection completely.
Gastric cancer remains a significant global public health problem. Although in developed countries its incidence has dramatically decreased, on a worldwide scale it is still a leading cause of cancer-related deaths. Surgery is the only potentially curative treatment for gastric cancer. Although the survival rates for patients with early stage disease (stage 1A and 1B) are good, this subgroup of patients constitutes only 20% of those undergoing resection. The majority of patients will have locally advanced or metastatic disease at presentation, which has an extremely poor prognosis. The current five-year survival rate for gastric cancer in Western countries is approximately 20-30%, a figure that has improved little over the past 30 years. The intervention arm in TOPGEAR consists of pre-operative chemotherapy, pre-operative chemoradiotherapy, surgery and post-operative chemotherapy. The control arm consists of pre-operative chemotherapy, surgery and post-operative chemotherapy. The primary objective of TOPGEAR is to investigate whether the addition of chemoradiotherapy to chemotherapy is superior to chemotherapy alone in the neoadjuvant setting by improving pathological complete response rates in the first instance, and subsequently overall survival, in patients undergoing adequate surgery (D1+ dissection) for resectable gastric cancer.
This study is a phase III, multi-centre study of olaparib in combination with paclitaxel, compared with placebo in combination with paclitaxel in patients with advanced gastric cancer who have progressed following first-line therapy. Patients will be from China, Japan , Korea and Taiwan.
Docetaxel is currently one of standard second-line therapy in patients with gastric cancer. As angiogenesis and FGFR pathway has been suggested to be associated with gastric cancer, dovitinib, dual VEGFR and FGFR inhibitor, may have the potential to improve the outcomes of patients with gastric cancer. Therefore, we investigated the combination regimen of docetaxel and dovitinib.
Gastric cancer is still one of the main health care issue and gastrectomy with lymph node dissection is the only chance to be cure. Even though the development and standardization of gastric cancer surgery, the morbidity of gastric cancer surgery was reported around 20% with less than 1% of mortality in East. In contrast, around 40% of morbidity and 10% of mortality was reported in West. There has been several indexes which can define the complications after surgery, but adapting it into clinical practice is sometimes difficult due to the heterogeneous opinion between surgeons. Thus for clear defining the complications after surgery, consensus between many surgeons and prospective cohort study is necessary. The purpose of this study is collecting the complications data after gastric cancer surgery and defining it with every week meeting by at least 6 or more surgeons' discussion.
multi-center, prospective, randomized, open-label phase III
Background: - Recent advances in cancer research have led to new therapies to treat the disease. It is important to continue these advances and discover new ones. To do that, researchers need tissue samples from solid tumors. This study will collect such samples from people already scheduled to have a procedure at the National Institutes of Health Clinical Center (NIHCC). Objectives: - To collect tissue samples for use in studying new ways to treat tumors. Eligibility: - Adults 18 years and older, with a precancerous or cancerous solid tumor who are scheduled to have surgery or a biopsy at the NIHCC. - Children under the age of 18 but who are older than 2 years of age are eligible to be enrolled on the research sample collection portion of this study if they will have a biopsy or surgery as part of their medical care. Design: - Before their procedure, participants will have a small blood sample taken. - Some participants will undergo leukapheresis. In this procedure, blood is removed through a tube in one arm and circulated through a machine that removes white blood cells. The blood, minus the white blood cells, is returned through a tube in the other arm. The procedure takes 3-4 hours. - For all participants, during the surgery or biopsy, pieces of the tumor and pieces of normal tissue near it will be removed for this study. The rest of the tumor or precancerous growth will be sent to a lab for analysis. - Participants will return to the clinic about 6 weeks after the operation for a routine checkup. Some may have to return for additional follow-up.
