15 Recommendations on surveillance strategies should be based on duodenal cancer risk. In this issue of JGH, Bai and Li describe an interesting series of 210 Chinese gastric cancer patients aged below 35 years,16 and compared the endoscopic, clinicopathologic features, and survival of these patients with a control group of 210 patients with gastric cancer diagnosed at selleck screening library older age. In this patient series, several of the specific abovementioned features characterizing gastric cancer diagnosed at young age were confirmed; female predominance, high proportion of carcinomas

of the diffuse type, high percentage of patients with a family history of gastric cancer, and a majority of cancers localized in the gastric corpus. An important clinical aspect is that early diagnosis of gastric cancer in young patients is hindered by the absence of alarm symptoms in a large proportion of patients. The study of Bai and Li shows that about two thirds of their young gastric cancer patients lacked alarm symptoms, as compared to less than half of patients at older age. Unfortunately, young patients with gastric cancer also tend to show a poor prognosis as a result of advanced disease at diagnosis so that only limited curative options are available. Although published reports data on this point are conflicting. Bai and Li show that in cases where the stage of gastric cancer allows surgical resection, survival

PF-562271 molecular weight rates of young and older patients are similar. In conclusion, the study of Bai and Li provides a fine overview on the specific patient characteristics of young gastric cancer patients. Individual cases should always be assessed for the presence of an underlying hereditary condition, which is of outmost importance for follow-up, and for the management of family members. Additional investigation of a potential increase of the incidence of gastric cancer diagnoses at young age is required, as this may identify important risk factors for cancer development in this selection

of patients. “
“Loss of 16q is one of the most frequent alterations in many malignancies including hepatocellular carcinomas (HCC), suggesting the existence of a tumor suppressor Masitinib (AB1010) gene (TSG) within the frequently deleted region. In this report we describe the identification and characterization of one candidate TSG, tyrosine aminotransferase gene (TAT), at 16q22.1. Loss of one TAT allele was detected in 27/50 (54%) of primary HCCs by quantitative real-time polymerase chain reaction. In addition, homo-deletion of TAT alleles was detected in two cases. Down-regulation of TAT was detected in 28/50 (56%) of HCCs, which was significantly associated with the loss of TAT allele and hypermethylation of TAT 5′ CpG island (CGI) region (P < 0.001). Functional studies found that TAT has a strong tumor suppressive ability. Introduction of the TAT gene into HCC cell lines could effectively inhibit colony formation in soft agar, foci formation, and tumor formation in nude mice.
