Abstract:
Objective:To analyze the clinicopathological features and prognostic factors of alpha‐fetoprotein‐producing gastric carcinoma (AFPGC).Methods:A retrospective analysis was made on 2 671 GC patients admitted from Jan 1998 to Dec 2018 , AFPGC patients and matching AFP negative GC cases were enrolled and their clinicopathological features and prognostic factors were analyzed. The survival curve was drawn by Kaplan-Meier method. Log-rank test was used to test the significance, Univariate analysis was performed by using COX proportional hazard model.Results:There were 98 AFPGC in this study accounting for 4.5% of all GC of the corresponding time period. The proportion of male to female was 2.16∶1, the average age was (65±12) years. The serum AFP levels significantly decreased after operation in most patients (median: 52 ng/ml vs. 5 ng/ml, Ｚ=-2.736, P=0.001). Serum AFP and CEA levels in patients with AFPGC before treatment were significantly higher than that in patients with AFP negative GC (both P<0.05) . Vascular invasion(62.71% vs. 40.68%) and liver metastasis (31.63% vs .6.12%) were more likely to occur in AFPGC groups (both P<0.05). However, there was no significant difference between the two groups in tumor size, location, differentiation and lymph node metastasis (all P>0.05). The prognosis of AFPGC was significant pooer than that in AFP negative GC ( P<0.05). Prognosis of AFPGC patients was significantly correlated with preoperative serum AFP level, TNM stage, lymph node metastasis, simultaneous liver metastasis and vascular invasion (all P<0.05) . COX multivariate survival analysis found that preoperative serum AFP level was independent risk factors of patients with AFPGC ( P<0.05). Conclusion:AFPGC is a special GC charactering poor prognosis .
