Filter by:The study objective is to collect prospective data on cancer patients who undergo surgery and intraoperative imaging. The registry will include (but not limited to) cancer type, stage, intraoperative challenges to the surgeon, usage and results of intraoperative imaging, and recurrence surveillance.
One paraffin block is routinely used for Human Epidermal Growth Factor Receptor 2 (Her2/neu) immunohistochemistry (IHC) assessment. Here, investigators investigated if picking two or multiple paraffin blocks for Her2/neu evaluation is an economical, efficient and practical method, which may reduce false-negativity of Her2/neu IHC assessment due to intratumoral heterogeneity.
The purpose of this study is to evaluate sensitivity and specificity of newly defined tumor biomarker with gastric cancer pts and cancer-free healthy volunteers.
The purpose of this study is to explore the safety and feasibility of the Laparoscopic Spleen-Preserving No. 10 Lymph Node Dissection for patients with locally advanced upper third gastric adenocarcinoma（cT2-4a, N-/+, M0）.
The aim of this study was to compare the efficacy and safety of POF, FOLFOX, and FOLFOX plus paclitaxel(ip) as first-line treatment in AGC a phase II clinical trial.
Stage I of the Thoracic-POISE study will pilot-test a broad-based, multi-agent integrative care intervention delivered by naturopathic doctors in conjunction with standard surgical and oncologic care of people with thoracic cancer.
Background: Gastric cancer (GC) is major global health concern and the second leading cause of cancer deaths worldwide. Amplification of Her2/neu gene and/or overexpression of the Her2/neu protein have been observed in GC. Trastuzumab (Herceptin™) is an anti-Her2/neu antibody, which has been successfully applied in GC. However, the intratumoral heterogeneity of Her2/neu overexpression and amplification in GC should be noticed. The investigators investigated the significance of evaluating Her2/neu expression in different paraffin blocks of tumor tissue in GC. Methods: 2000 GC patients from ten centers, patients were divided into a cohort using one tumor tissue paraffin block (cohort 1, n=1000) and a cohort using dual tumor tissue paraffin blocks (cohort 2, n=1000) when evaluating Her2/neu expression status by immunohistochemistry (IHC). In cohort 2, the investigators combined the results from two different paraffin blocks and used the higher one as the final score.
The purpose of this study is to evaluate the safety and effectiveness of CAR-pNK cell immunotherapy in patients with MUC1 positive relapsed or refractory solid tumor.
Billroth-II (gastrojejunostomy) is one of major option after gastrectomy for gastric cancer. The investigators hypothesized that isoperistaltic anastomosis lead to higher incidence of dumping syndrome but antiperistaltic (anisoperistaltic) anastomosis have relevance to gastric stasis or obstruction. The investigators will assess complications, dumping syndrome and quality of life between isoperistaltic and antiperistaltic after distal gastrectomy for gastric cancer.
Helicobater pylori plays an important role in the development of gastric cancer. Eradication therapy can reducing the morbidity of gastric cancer, but can't totally prevent it especially when atrophy and more serious precancerous lesions already happened. Prior studies found the gastric bacterial difference among gastritis, intestinal metaplasia and gastric cancer. However, they didn't reach an agreement. Correa's model is widely accepted in the development of gastric cancer. The pathological change makes a more suitable environment for bacteria to overgrowth. This study are designed to analyze the gastric microbial difference of non-atrophic gastritis, atrophic gastritis, intestinal metaplasia, intraepithelial neoplasia and gastric cancer.
