Filter by:Follow-up after successful operative treatment of cancer in the esophagus, stomach or pancreas in order to detect recurrent disease is a controversial topic. This is because the methods and the consequence of following these patients is unknown. Therefore the investigators will randomize these patients in to two groups: 1. One group of patients will be offered visits with a specialist surgeon in a outpatient setting for a clinical evaluation every 3,6,9,12,18 and 24 months after surgery, as is the current standard at our department. 2. The other group will be offered Endoscopic UltraSound, EUS, and PET/CT with the same intervals as the first group.
The overall objective of this pilot study is to determine whether multispectral imaging increases the diagnostic accuracy of the current standard of high-definition white-light endoscopy for the detection of gastric neoplasia (high grade dysplasia or cancer). As part of an NCI-funded RO1, the investigators goal is to develop a multispectral endoscopic platform that can be used to survey a large surface area and, potentially, serve as a "red flag" for microendoscopic imaging of small areas. In prior ex vivo evaluations of surgical and endoscopic specimens, the investigators have identified the optical settings and illumination wavelengths that are complementary to white-light imaging and enhance superficial mucosal and vascular changes associated with neoplasia. Based on this initial testing, vital-dye enhanced fluorescence imaging (VFI) and imaging with High Resolution Microendoscope (HRME) have been identified as modalities that may be complementary to white-light imaging. The goal of this pilot study is to preliminarily determine the accuracy of these modalities during the endoscopic surveillance and detection of gastric neoplasia.
This dose-escalation study is to determine the safety, maximum tolerated dose (MTD) and efficacy of KD019 in combination with trastuzumab and mFOLFOX-6.
The purpose of this study is to find out whether either trastuzumab or the combination of trastuzumab and pertuzumab with standard chemotherapy shows more activity against gastro-oesophageal adenocarcinoma than standard chemotherapy given before and after surgery and it can be safely administered.
Intraperitoneal chemotherapy as an adjuvant treatment modality is designed to eradicate intraperitoneal free tumor cells that can be a source of peritoneal carcinomatosis. Although we have not reached unanimous consensus, favorable reports on the outcome of intraperitoneal chemotherapy have been published. In this study, we review the clinicopathological characteristics of patients and effects of early postoperative intraperitoneal chemotherapy (EPIC) on overall and gastric cancer-specific survival and patterns of recurrence of gastric cancer patients with macroscopic serosal invasion. The aim of this study is to evaluate the impact of intraperitoneal chemotherapy on overall and disease free survival of advanced gastric cancer patients with serosal invasion after potentially curative surgery.
In gastric cancer patients treated with 5-FU and cisplatin, higher tumor TS levels were associated with a less favorable response (29% vs. 68%; p=0.024). Similarly, in a study in which patients were treated with high dose 5-FU, patients with high TS expression had a response rate of only 12.5%. Conversely a response rate of 92.9% was observed in patients with low tumor TS expression. A longer but not statistically significant survival advantage was observed in patients with the TSER*2 allele compared with the TSER*3/*3 patients. Additionally, a review by Patel et al. identified approximately 20 gastric cancer studies that have found a positive association between TSER genotype and clinical response (in either direction). Therefore, the primary goal of this proposal is to prospectively genotype patients, select patients with "good risk" TSER genotypes (TSER*2*/*2 or *2/*3) and treat them with a standard 5-FU containing regimen (FOLFOX) in order to improve clinical outcomes, while randomize patients with the "poor risk" TSER genotype (*3/*3) to either the standard 5-FU containing regimen or another non-5-FU-based regimen (docetaxel/cisplatin).
The aim of this study is to evaluate the feasibility and safety of no use of antimicrobial prophylaxis during laparoscopic distal gastrectomy for gastric carcinoma.
This study is to evaluate the efficacy of GUARDIX-SGⓇ for patients with gastrectomy in Korea and the investigators hypothesized applying of adhesive preventing agent would reduce incidence of adhesive obstruction after gastrectomy.
It is thought that the development of cancer of the stomach follows a series of stages in which the lining becomes increasingly abnormal. Early detection of precursors of gastric cancer likely enable less invasive treatment. The assessment of gastric mucosa using the endoscope is used to detect cancers and these precursor lesions. Narrow band imaging uses filtered light already built into modern endoscopoes to identify the early changes in the gastric lining. The investigators' hypothesis is that narrow band imaging improves detection of precursor lesions and is a method amenable to international standardization. The investigators will conduct a prospective trial in which standard random biopsy, white light guided biopsy, and narrow band imaging guided biopsy will be performed for each patient. The yield of the different methods for gastric cancer precursors will thus be compared.
This study is designed to assess what is the better neoadjuvant chemotherapy regimen for patients with initially unresectable locally advanced gastric cancer.
