Filter by: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.
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.
Adjuvant chemotherapy followed by curative gastrectomy for Stage II/III gastric cancer has improved disease free time and survival. However, there are still considerable number of patients experience relapse even after adjuvant chemotherapy. In an attempt to select patients who really benefit the postoperative adjuvant chemotherapy, we have identified potential biomarkers (NF-kappaB/JNK) from cell line panel screening followed by immunohistochemical validation. In the present study, we further validate the significance of the biomarkers in a larger set of clinical samples to see if chemotherapeutic response can be determined immediately after surgery.
A study of Raltitrexed plus Docetaxel versus Docetaxel as second-line chemotherapy in subjects with Gastric Cancer.The purpose of this study is to compare the activity of Raltitrexed plus Docetaxel versus Docetaxel as second-line chemotherapy in subjects with gastric carcinoma by estimating progression free survival (PFS) in each treatment arm.
Background: It is shown that TS-1 as adjuvant chemotherapy after D2 resection in patients with gastric cancer can improve DFS and OS in one Japanese Trial. And TS-1 has become one of the standard therapies to these patients. But it is still unknown whether it would improve more to OS and DFS than single TS-1 after combined with oxaliplatin . This trial is designed to investigate the efficacy and safety of TS-1 plus oxaliplatin versus TS-1 single as adjuvant chemotherapy after D2 resection in patients with gastric cancer. Patients and methods: In this study , patients with histologically confirmed gastric cancer who received D2 resection and staged II or III, aged from 18 to 70 years and with Eastern Cooperative Oncology Group performance status ≤2 and adequate organ function, are randomized 1:1 to oxaliplatin 100mg/m2 on day 1 and TS-1 40~60mg twice everyday for 14 days in a 21-days cycle for total 6 cycles followed by TS-1 single with the same dose and frequency to the end of the 1st year postoperatively(SOX) , or TS-1 single 40~60mg twice everyday for 14 days in a 21-days cycle to the end of the 1st year postoperatively (TS-1). The primary end point is overall survival (OS), and secondary end point is disease free survival(DFS) and safety. Final study analysis will be conducted in the end of the 5th year after the last patient's enrollment.
The optimal regimen for adjuvant treatment has not been established in GC yet. We plan to compare TS-1, TS-1/oxaliplatin with or without RT in D2 resected gastric cancer.
Stage 1:First line therapy Sequential therapy of S1+Docetaxel followed by S1 is superior to concomitant S1+Docetaxel in the safety and clinical efficiency. Stage 2:Second line therapy To explore the feasibility of single drug(S1) maintenance treatment for advanced gastric cancer.
This study evaluate whether treatment of Helicobacter pylori infection reduces the incidence of gastric cancer in subjects with family history of gastric cancer.
Primary objective of the study is to compare requirement of blood transfusion and mortality in patients receiving Tranexamic acid (Cyklokapron®) and those not receiving it. Secondary objective is to; assess the re-bleeding events; need for surgical intervention; length of stay in Intensive care unit in between the two groups.
The purpose of this study is to assess the safety and efficacy of S-1 plus oxaliplatin combination chemotherapy based on the adverse events and survival period by performing a phase I/II study of this combination in patients with D2 resection of gastric cancer.
