Summary progression-free survival (PFS) was 1.59 months (95% CI 1.24-1.94 months). Summary overall survival (OS) was 5.72 months (95% CI 0-12.19 months). A subset of patients derived long-term benefits as seen in other cancer locations. The adverse effect rate was low and consistent with that in other disease locations. Low efficacy of immune checkpoint inhibitors as a class in gastric or gastroesophageal junction adenocarcinomas is observed in this analysis and stresses the need for effective biomarker use for the identification of most probable responders.

Euroasian J Hepato-Gastroenterol 2020;10(2)56-63. To assess the effect of nonsurgical treatment on salivary hepatocyte growth factor (sHGF) levels in a population with periodontal disease a quasi-experimental study. Eighty-one patients (aged 30-70 years) were divided into three groups based on the gingival index, probing depth, clinical attachment loss, and radiographic evidence of bone loss healthy (group I), gingivitis (group II), and chronic periodontitis (group III). Saliva samples were collected from these groups at baseline. At 8 weeks, saliva samples were collected again from group II and group III after the patients went through nonsurgical periodontal treatment. The levels of HGF were estimated using enzyme-linked immunosorbent assay (ELISA). The clinical parameters and HGF levels among all groups were analyzed using a one-way analysis of variance (ANOVA) using SPSS 17 version. At baseline, the highest mean HGF concentration in saliva was observed for group III (3455.83 ± 1463.44 pg/mL), and the least in group I (469.43 ± 317.
