title: Modified glasgow prognostic score as a prognostic factor in gastriccancer patients: a systematic review and meta-analysis.
abstract: OBJECTIVE
  Modified Glasgow prognostic score (mGPS) had been reported to associate with the prognosis ofgastric cancer (GC), butits significance in gastric cancer patients has not been studied fully.
  
  
  METHODS
  PubMed; EMBASE; Web of Science and CNKI data base were searched to identify studies using the mGPS in gastric cancer patients. Outcome measures that were evaluated included overall survival (OS), lymphatic invasion and venous invasion inpatients with gastric cancer.
  
  
  RESULTS
  A total of seven studies comprising 3206 patients were included in the meta-analysisof which all used OS as an outcome measure, three studies reported lymphatic invasionand three evaluated venous invasion. The results show that OS was worse in patients with an mGPS=1 and 2 (odds ratio [OR]=2.54, 95% [CI]: 1.62-3.98 and OR=12.02, 95% [CI]: 6.79-21.28, respectively) compared with those with a score of 0 (both P<0.01). Furthermore, gastric cancer patients with mGPS≥1 have higher rates of lymphatic and venous invasion with ORs of 2.51 (95% CI: 1.80-3.51) and 2.63 (95% CI: 1.35-5.11) respectively (both P<0.01).
  
  
  CONCLUSIONS
  Them GPS could be used as a prognosis predictorfor gastric cancer patients and associated lymphatic and venous invasion.
