Reagent kit for auxiliary diagnosis of hepatoma

The invention discloses a reagent kit for auxiliary diagnosis of hepatoma. The reagent kit provided by the invention comprises a compound for detecting Rab27B gene expression. The application of the compound for detecting the Rab27B gene expression in preparing the reagent kit for the auxiliary diagnosis of the hepatoma also belongs to the protection range of the invention. The compound for detecting the Rab27B gene expression is 1 or 2 as follows: 1. a PCR primer of a cDNA for detecting an Rab27B gene; 2. a monoclonal antibody or a polyclonal antibody for detecting Rab27B albumen. Experiments prove that the concentration mean value of the Rab27B albumen of an LMS group (no metastatic group recurs within two years when in blood collection) is 2.08ng/mul, the concentration mean value of the Rab27B albumen of an HMS group (a metastatic group occurs within one year when in blood collection) is 7.03ng/mul, the concentration mean value of the Rab27B albumen of an AMS group (the metastatic group occurs when in blood collection) is 17.80ng/mul, and the albumen contents among the three groups have marked differences.
