Abstract
Gastric carcinoma is one of the most common malignancies nowadays, and caner antigen 72-4 (CA 72-4) in gastric juice has been rarely studied. To compare CA 72-4 in gastric juice pre- and post-distal gastrectomy (DG) and analyze its possible significances, we selected 64 patients diagnosed with gastric carcinoma who underwent DG and collected their perioperative gastric juice samples whose contents of CA 72-4 were detected. We found that CA 72-4 in gastric juice pre-gastrectomy is significantly higher among patients in advanced stages and correlated with tumor TNM classification (P < 0.01), within which tumor size, levels of gastric wall invaded, and number of metastatic lymph nodes are significant influencing factors (P < 0.05); CA 72-4 in gastric juice post-gastrectomy is significantly higher than that pre-surgery (P < 0.01), and it is significantly correlated with tumor TNM classification and radical degree (P < 0.01), and regards the sum of distances from tumor to two cutting edges and the classification of cutting edge as significant impact factors (P < 0.05); nine patients whose CA 72-4 in gastric juice rose post-DG show features indicating poor prognosis; the difference of CA 72-4 in gastric juice between pre- and post-gastrectomy is significantly correlated with tumor TNM classification and radical degree (P < 0.05), and regards tumor size, levels of gastric walls invaded, the sum of distances from tumor to two cutting edges and the classification of cutting edge as significant influential factors (P < 0.05). We conclude that CA 72-4 in gastric juice pre- and post-gastrectomy can provide us with much information about tumor and radical gastrectomy and that CA 72-4 in gastric juice post-gastrectomy and the difference of CA 72-4 in gastric juice between pre- and post-gastrectomy may indicate prognosis.
