More attention should be paid to adult gastric cancer patients younger than 35 years old: extremely poor prognosis was found.

ABSTRACT: Purpose: Several studies have reported controversial results about prognosis of gastric cancer in young age patients. The difference may partially result from variable definitions of young age. The aim of this study was to find out the relation between age and prognosis of gastric cancer patients, and to analyze the clinicopathological features and prognostic factors in young gastric cancer patients. Methods: Data queried for this analysis included GC patients from the Surveillance, Epidemiology, and End Results Program database from 1973 to 2014. Gastric cancer patients (N=79,505) diagnosed with an age?18 were included. By combining patients with similar prognosis, we figured out 3 cutoff values of age, 35 years old, 65 years old and 75 years old. We divided patients into 4 groups: young age patients: 18-34 years; middle-age patients: 35-64 years; elderly patients: 65-74 years; extremely elderly patients: >74 years. GC patients from Sun Yat-sen University Cancer Center (SYSUCC) were used as external validation data. Results: The clinicopathological features of young age gastric cancer patients included: poor-differentiated, diffuse type of cancer, and advanced stage at diagnosis. The median survival of patients <35 years old was significantly lower than middle-age patients (35-64 years) and elderly patients (65-74 years) (12 months vs. 15 and 16 months, respectively, both p <0.001). Location of tumor, ethnicity, tumor size, surgery and TNM stage were independent prognostic factors by multivariate analysis in young patients. The poor prognosis for young patients remained valid in the SYSUCC database. Conclusions: Our results demonstrated that gastric cancer patients <35 years old had an extremely poor prognosis. Early detection of gastric cancer is of paramount importance in young age people.

Project description:Colorectal cancer (CRC) is the third most diagnosed cancer worldwide and second leading cause of cancer death. Most CRCs arise from a polyp, developing through two major precursor lesion pathways: the traditional adenoma-carcinoma pathway, and the serrated neoplasia pathway. This provides opportunities to prevent cancer by removing its precursor lesions. CRC screening efforts are directed toward removal of precancerous polyps with colonoscopy and detection of early-stage CRC, which has been demonstrated to reduce CRC incidence and mortality effectively, making CRC one of the most preventable and treatable forms of cancer. Current guidelines in China recommend starting CRC screening uniformly at age 50 in average-risk individuals. However, a one-fits-all approach to determining CRC screening starting age may be not conducive to personalized screening, especially in the developing countries with scarce health resources. The incidence of early-onset CRC (CRC diagnosed before the age of 50) has shown a continuous increasing trend worldwide, spurring the US Preventive Services Task Force to recommend initiating average-risk CRC screening at age 45 instead of 50. Furthermore, different populations may benefit from even earlier screening, and CRC incidence may differ on the basis of population characteristics and CRC risk factors. For individuals younger than 50 years old, earlier screening based on risk factors may address this concern. Previous studies have recommended earlier starting age of CRC screening combined with risk factors such as but not limited to sex, age, family history, lifestyle and comorbidity. Some upper gastrointestinal diseases have also been reported to be associated with an increased risk of colorectal neoplasms, which may be related to the destruction of gastric acid barrier function and long-term use of pump proton inhibitors. Compared with colonoscopy examination, individuals were more willing to undergo esophagogastroduodenoscopy (EGD) examination for gastric cancer screening, especially among the younger, potentially utilizing the EGD to guide earlier colonoscopies for patients at increased risk. Therefore, this study was aimed to investigate the association between esophagogastric histopathology and colorectal neoplasms in patients under the age of 50 and whether these risks factor could be combined with to guide earlier CRC screening.
