Clinical characteristics and treatments of patients with alpha-fetoprotein producing gastric carcinoma

Year, pages: 2018, 326 - 330

Alpha-fetoprotein (AFP) is a well-known tumor marker of hepatic carcinoma and yolk sac tumor. Alpha-fetoprotein producing gastric carcinoma (AFPGC) is a rare type of gastric cancer with high malignancy and poor prognosis, which make it different from other types of gastric cancer. This rare gastric cancer patient subgroup is likely frequently misdiagnosed which may be related to lack of knowledge of the disease. The purpose of this article is to summarize the mechanism of AFP positive gastric cancer, classification, biological behavior and treatment, in order to assist clinical practitioners to detect AFPGC earlier and treat it better. Previous studies have showed that AFPGC has a complex pathophysiology mechanism. AFPGC is more aggressive and characterized by stronger proliferation, neovascularization, lymphatic invasion and distant metastasis. Furthermore, so far there has been no standard treatment for patients with AFPGC. Nevertheless, our present study summarizes some effective treatments based on previous research outcome. In conclusion, the present study demonstrates that the importance of detecting AFP routinely in serum and tissues in gastric cancer cases, which will greatly improve the diagnosis rate of AFPGC, and in regards to treatment, surgery, chemotherapy, targeted therapy and interventional treatment may have positive impacts on AFPGC treatment outcome. However, further study with a larger sample is required to confirm the reliability and validity of these methods.
