title: [The significance of pepsinogen with its subgroup and CA72-4 associate detect applied to early diagnostic and prognosis judgment on gastric cancer].
abstract: OBJECTIVE
  To find out the connection of serum pepsinogen and it's subgroups (PGI, PGII) with CA72-4 to early diagnosis and postoperative recurrence on gastric cancer.
  
  
  METHODS
  RIA was applied to detect the results of serum PGI, PGII and CA72-4 on gastric cancer and other stomach diseases, then the clinic value of associating detection on gastric cancer diagnosis and prognosis judgment were assessed.
  
  
  RESULTS
  The serum PG levels of GC patients were significantly lower comparing to those of healthy controls (P < 0.01), apparent changes had taken place on earlier period GC (P < 0.05), and aggressive GC were even lower (P < 0.01). On the earlier period of GC diagnosis, CA72-4 levels were not apparently different to healthy controls (P > 0.05), and aggressive GC were significantly higher (P < 0.01). Compared preoperative with postoperative, the serum PGI and PGII and CA72-4 levels were significantly different (P < 0.01). In the patients underwent total gastrectomy, both of pepsinogen levels were lower than those of subtotal or large partial gastrectomy (P < 0.05). The serum PGI, PGII and CA72-4 levels of patients with recurrence of GC after total gastrectomy were significantly higher than those without. Compared before recurrence patients with after ones, the serum PGI and PGII levels of partial gastrectomy were no apparent difference (P > 0.05), however apparent changes had taken place on CA72-4 levels. The associate detection had even higher specificity (P < 0.01).
  
  
  CONCLUSIONS
  Apply to detect the serum PG levels on crowds, especially pGI, PGI/II levels decrease, which may be expected to become the index to earlier period GC screening. The associating detection to PG and CA72-4 levels may significantly improve sensitivity and specificity, which have chances to be applied to monitoring to postoperative gastrectomy.
