Clinicopathologic features, serum AFP level at diagnosis and changes during treatment, first-line chemotherapy regimens, efficacy and toxicity, and survival information were collected. A Person's χ~2 or Fisher's exact test was used to measure the differences between variables. Survival prognostic factors were investigated using the Kaplan-Meier method and Cox regression.RESULTS Median serum AFP level was 161.7 ng/m L(range, 22.9-2557110 ng/m L). Objective response rates(ORR) was significantly lower in the AFP ≥ 160 ng/m L group than in the AFP < 160 ng/m L group(30.4% vs 68.3%, P < 0.001). ORR to doublet regimens was significantly lower in the AFP ≥ 160 ng/m L group, whereas ORR to triplet regimens was similar between the two groups. Liver metastasis rate was significantly higher in the AFP ≥ 160 ng/m L group than in the AFP < 160 ng/m L(69.8% vs 50.0%, P < 0.001). Overall survival(OS) in the two cohorts did not show any significant difference(P = 0.712). Dynamic changes of AFP were consistent with response to chemotherapy, and median OS of patients with a serum AFP decline ≥ 50% and those with a serum AFP decline < 50% was 17.5 m and 10.0 m, respectively(P = 0.003). Hepatic(P = 0.005), peritoneal(P < 0.001), non-regional lymph node metastasis(P < 0.001), and portal vein tumor thrombus(PVTT)(P = 0.042) were identified as independent prognostic factors for AFPAGC. CONCLUSION Real-time examination of AFP has great predictive and prognostic value for managing AFPAGC. For those with markedly elevated AFP, triplet regimens may be a better choice.展开更多
