Hyponutrition among newly diagnosed gastric cancer.

OBJECTIVES: This study aims to determine the malnutrition status among Vietnamese patients newly diagnosed with gastric cancer (GC). BACKGROUND: GC remains the top rank of common and deadly diseases. With limited clinical manifestation, most GC patients were diagnosed at late stages when tumor is not radically resected. Malnutrition was associated with poor prognosis of GC, such as prolonged hospitalization, limited treatment efficacy and low survival rate. METHODS: The cross-sectional descriptive study recruited 77 patients newly diagnosed with GC and 90 healthy individuals (HC). The data used for this study were approved by the local Ethical Committee. The data were analysed on STATA 14.0 and GraphPad Prism 8.0. RESULTS: We observed the male dominant distribution in GC cohort and over 65% of GC were firstly diagnosed at advanced stages (III and IV). Anemia was detected in about 50% of GC patients. Hyponutrition was prevalent in newly diagnosed GC. We found the decreased tendency of anemia related indexes from HC to early stages (I and II) and advanced stages (III and IV) of GC patients. CONCLUSION: Anemia and hypoproteinemia occurred frequently among Vietnamese newly diagnosed GC. The nutrition therapy would benefit GC patients (Tab. 4, Fig. 4, Ref. 20).

Adiponectin Receptor Agonist Effectively Suppresses Hepatocellular Carcinoma Growth.

Hepatocellular carcinoma (HCC) is the second lethal cancer. Short overall survival, low five-year survival rate, and unimproved treatment efficacy urge the need to improve HCC prognosis. Adiponectin is key protector against cancer and hepatic abnormalities. Hypoadiponectinemia occurs in and promotes carcinogenesis and hepatic diseases. Adiponectin reactivation by different methods showed impressive effect against cancer and hepatic diseases. Recently, AdipoRon, an adiponectin receptor agonist, can interact with both Adiponectin receptors. AdipoRon showed promising anti-cancer effect in some cancers, but no study on HCC yet. The in vitro effect of AdipoRon on HCC was investigated by cell viability, migration, invasion, colony formation and apoptosis assays. The signalling alteration was determined by RT-qPCR and Western blot. The effect of treatment was interpreted by comparison between treatments and control. The difference between two cell lines was relatively compared. Our results showed significant in vitro anti-cancer effect of AdipoRon via AMPK- and dose-dependent manner. Huh7 cells showed a lower level of AdipoR1/2 and a superior proliferation and aggressiveness, compared to Hep3B. In addition, Huh7 cells were more sensitive to AdipoRon treatment (lower IC50, less cell growth, migration, invasion and colonies upon AdipoRon treatment) than Hep3B cells. In conclusion, AdipoRon effectively inhibited HCC growth and invasiveness in vitro. The deficient expression of adiponectin receptors affects efficacy of AdipoRon and aggressiveness of HCC cells.

The diagnostic and prognostic value of neutrophil-to-lymphocyte ratio and platelet-to-lymphocyte ratio on gastric cancer patients.

Gastric cancer (GC) is the remaining concern of cancer-associated health burden. Valuable predictive and prognostic indicators support the early diagnosis and improve outcome. Immune escape and inflammation are important cancer hallmarks. The prognostic and diagnostic value of platelet-to-lymphocyte ratio (PLR) and neutrophil-to-lymphocyte ratio (NLR) was reported in some cancers. But these cheap and convenient indexes are far from clinical use. Thus, investigation the alteration of those index on GC is needed to impose the use of those indexes in clinic. The study recruited seventy-seven hospitalized patients newly diagnosed with GC and 90 healthy individuals. The clinical and preclinical data of participants were collected from Hospital Information Management system. This study were approved by the Ethical Committee, Vietnam Military Medical University. The data were analyzed on STATA version 14.0 and GraphPad Prism 8.0. The alteration of immunological system was reported by significantly higher white blood cell count, neutrophils, platelets, PLR, and NLR as well as decreased lymphocytes on GC, compared to healthy individuals. Those indexes were elevated on advanced stage GC, compared to early stage GC. Our receiver operating characteristic curve analysis showed the significant specificity and sensitivity of PLR (cutoff 135.0) and NLR (cutoff 2.0) on GC diagnosis with respective area under receiver operating characteristic curve of 84.74% and 85.17%, P < .0001. Besides, our results reported the tendency of increased PLR and NLR and short time from clinical signs to being diagnosed. PLR and NLR have significant specificity and sensitivity in diagnosis and prognosis of GC.
