ABSTRACT
ObjectiveTo analyze the clinicopathological features and prognosis of gastric cancer patients with metastatic nodules of perigastric soft tissue. MethodsIn this study,1025 cases of gastric cancer received radical resection.According to the metastasis of perigastric soft tissue,patients were divided into metastatic group ( group MP,n =334 ),non-metastatic group ( group NMP,n =691 ).The clinicopathological features and prognosis were compared between the two groups. ResultsIn group MP,the ratio of upper,middle,lower,total gastric cancer was 25.8%,22.0%,51.4%,0.9% and the ratio in group NMP was 33.2%,21.3%,41.3%,4.2% respectively,showing significant higher ratio of upper and total gastric cancer in MP group(P =0.000). In group MP 47.3% cases with tumor size ≥5 cm,significantly higher than that in NMP group(27% ) (P =0.000).Lymph node metastatic ratio between 21% -40% and 41% -100% was found in 24.4% and 37.3% in MP group respectively,significantly higher than that of 12.9%,10.8% in NMP group(P =0.000).20.1% cases had distal metastasis in group MP,significantly higher than that of 4.1% in group NMP(P=0.000).In group MP and NMP group,the ratio of Borrmann infiltration typing was 82.1% vs.64.6%,the ratio of positive CEA was 21.2% vs.11.4%,the ratio of lower or undifferentiation typing was 78.7% vs.64.2%,all with significant difference (P =0.000 ). COX regression analysis showed the infiltration depth,organic invasion,lymph node metastatic ratio,M staging,Borrmann typing,metastatic nodules was the independent prognostic factors.Prognosis was significantly poorer in the cases with perigastric soft tissues than without ( P =0.000 ).Stratified analysis showed that irrespective of tumor size,infiltration depth,lymph node metastatic ratio,CEA value,Borrmann typing,differentiation degree,the mean survival time was significantly shorter in MP group than that in group NMP(P < 0.005).In cases without distal metastasis,the prognosis was significant poorer in group MP than that in group NMP ( P =0.000 ),however,there was no significant difference between two groups in cases without distal metastasis ( P =0.076).ConclusionsPerigastric soft tissue metastasis was common in gastric cancer,more frequently seen in tumor ≥5 cm,or with organic invasion,lymph nodemetastaticration ≥ 21%, distalmetastasis, Borrmanninfiltrationtyping, loweror undifferentiation typing,positive CEA. Perigastric soft tissues metastasis was the independent prognotic factor for gastric cancer.
