Abstract

The invention provides application of a specific lectin composition in preparing a test carrier for identifying epithelial ovarian cancer, and a kit. Aiming at a saliva sample, the specific lectin composition comprises (1) a composition of PSA, SNA, MAL-II, ECA and HHL for a healthy crowd; (2) a composition of PHA-E, LTL and PNA for patients with benign ovarian diseases; (3) a composition of RCA120, UEA-I, ConA, LCA, AAL, WFA, WGA, DBA, VVA, NPA and GNA for patients with epithelial ovarian diseases. Through specific combining of lectin and glycoprotein carbohydrate chain in saliva, glycoprotein and a carbohydrate chain structure in differential expression in the saliva sample of a patient can be quickly detected, and multiple glycoprotein and carbohydrate chain structures in the sample canbe quickly detected in high flux.

Description

technical field

[0001] The invention relates to the use and kit of a lectin for identifying epithelial ovarian cancer based on salivary glycoprotein. Background technique

[0002] Ovarian cancer (Ovarian cancer, OC) is one of the most common tumors of the female reproductive system, ranking sixth among the most common cancers in the world, fifth among common female cancers, and seventh among the major cancers that cause death in women globally . In recent years, the incidence of ovarian cancer in my country has been on the rise. It is estimated that the incidence of ovarian cancer in my country will reach 6.43 / 100,000 in 2016. Due to the lack of obvious differential signs and screening methods, early diagnosis of ovarian cancer is very difficult. Clinical studies have shown that the 5-year survival rate of ovarian cancer patients diagnosed in the early stage (I / II) can reach more than 90%, however, about 70%-85% of the patients are already in the advanced stage (III / IV stag...
