S-1 is a novel oral fluorouracil antitumor drug that consists of tegafur which is a prodrug of 5-fluorouracil (5-FU); 5-chloro-2,4-dihydropyridine (CDHP), which inhibits dihydropyrimidine dehydrogenase (DPD) activity; and potassium oxonate (Oxo), which reduces gastrointestinal toxicity. 5-FU is metabolized by CYP2A6 and DPD. In this study, the researchers investigate the influences of differences in activities of CYP2A6 and DPD on pharmacokinetics and pharmacodynamics of S-1 and clinical outcomes in digestive organ cancer patients treated with S-1.

No accurate, inexpensive and non-invasive test for gastric cancer screening is currently available. The investigators' recent study identified a1-antitrypsin and other proteins as potentia...
The purpose of this study is to establish a gastric cancer registry. A registry is a database of information. With the registry, we can learn more about the genetic causes of gastric cance...
Since it is not uncertain about efficacy of combination therapy with PSK and TS-1 in gastric cancer, in this study, we compare efficacy and safety of postoperative adjuvant therapy using T...
Liquid biopsy has been widely used in the diagnosis and treatment of tumors, and cfDNA has always been a hot spot in clinical research. Previous studies have shown that cfDNA may be associ...
Familial gastric cancer accounts for 10% of all cases, but predisposing genetic variations is unknown except for CDH1 mutation. Because Germline mutation is believed to be a key aspect of...
Evidence regarding gastric cancer patients
Mongolia has the highest mortality rate of gastric cancer. The early detection of cancer and down-staging screening for high risk patients are essential. Therefore, we aimed to validate serum markers ...
Our goal was to evaluate changes in PD-L1 expression in primary tumours of metastatic gastric cancer before and after chemotherapy.
Gastric cancer (GC) is one of the high-incidence and high-mortality cancers all over the world. Though genome-wide association studies (GWASs) have found some genetic loci related to GC, they could on...
That portion of the stomach remaining after gastric surgery, usually gastrectomy or gastroenterostomy for cancer of the stomach or peptic ulcer. It is a common site of cancer referred to as stump cancer or carcinoma of the gastric stump.
A proto-oncogene protein and member of the Wnt family of proteins. It is frequently up-regulated in human GASTRIC CANCER and is a tumor marker (TUMOR MARKERS, BIOLOGICAL) of gastric and COLORECTAL CANCER.
A deoxycytidine derivative and fluorouracil PRODRUG that is used as an ANTINEOPLASTIC ANTIMETABOLITE in the treatment of COLON CANCER; BREAST CANCER and GASTRIC CANCER.
Abnormal distention of the STOMACH due to accumulation of gastric contents that may reach 10 to 15 liters. Gastric dilatation may be the result of GASTRIC OUTLET OBSTRUCTION; ILEUS; GASTROPARESIS; or denervation.
Vagal denervation of that part of the STOMACH lined with acid-secreting mucosa (GASTRIC MUCOSA) containing the GASTRIC PARIETAL CELLS. Since the procedure leaves the vagal branches to the antrum and PYLORUS intact, it circumvents gastric drainage required with truncal vagotomy techniques.

Head and neck cancers
Cancer can occur in any of the tissues or organs in the head and neck. There are over 30 different places that cancer can develop in the head and neck area. Mouth cancers (oral cancers) - Mouth cancer can develop on the lip, the tongue, the floor...
Cancer is not just one disease but many diseases. There are more than 100 different types of cancer. Most cancers are named for the organ or type of cell in which they start - for example, cancer that begins in the colon is called colon cancer; cancer th...
