AIM To investigate predictive and prognostic value of serum alpha-fetoprotein(AFP) level and its dynamic changes in patients with advanced gastric cancer with elevated serum AFP(AFPAGC).METHODS One hundred and five patients with AFPAGC were enrolled in the study, and all of them underwent at least one cycle of systemic chemotherapy at our institute and had serum AFP ≥ 20 ng/m L at diagnosis or recurrence. 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

A case with an Alpha-fetoprotein-producing(AFP-producing) carcinoma originating from the rectum was described.A 41-year-old man,who underwent a palliative surgery for rectal carcinoma,was diagnosed with occupying liver lesions and a remarkable AFP elevation(3484.61 ng/mL),and the AFP declined obviously 10 days after the palliative surgery.So we carried out a biopsy of the liver lesions.The histopathology was reported as low differentiation adenocarcinoma.The immunohistochemistry of the tumor cells via liver biopsy showed:Villin,CDX-2 was positive,Glypican-3 was partial positive,CK7,CK20,AFP,Hepatocyte were all negative.The initial histopathology was reported as an AFP-producing rectum adenocarcinoma with liver metastasis,which was a rare disease.So far,only 17 reports,none has been reported in China.Then,we summarize the characteristic of the disease:diagnosed with hepatic metastasis,raised serum AFP and a poor outcome,in addition to primary symptoms.This kind of disease is highly malignant. 展开更多
