Problems solved by technology

In the current research, people are still trying to find more sensitive and specific anti-TAAs autoantibodies for the diagnosis of ESCC. Although anti-TAAs autoantibodies have been reported in the literature, their sensitivity and specificity are low, and their clinical application value is limited.

Embodiment 1

[0031] Example 1: Eight kinds of serum autoantibodies are tested for early diagnosis of esophageal squamous cell carcinoma (small sample)

[0032] 1 Materials and methods

[0033] 1.1 Research object

[0034] A total of 150 serum samples were collected from Fujian Provincial Hospital from March 2015 to February 2016, including 50 early ESCC patients, 50 EBL patients, and 50 HC patients. All 50 patients with early ESCC were diagnosed on the basis of endoscopy combined with cytology or histopathology. They did not receive any anti-tumor treatment such as chemotherapy and radiotherapy. The TNM classification was stage 0, I, and II. The 50 cases of EBL patients came from patients who were initially treated in Fujian Provincial Hospital during the same period, including benign esophageal tumors, benign esophageal ulcers, esophageal erosion, and reflux esophagitis. Fifty HC patients were healthy adults from the Physical Examination Center of Fujian Provincial Hospital, which did n...

Embodiment 2

[0044] Example 2: Detection of four kinds of serum autoantibodies on the early diagnosis test of esophageal squamous cell carcinoma (large sample)

[0045] Based on the results of small-sample research, the purpose of this study is to study the value of anti-TP53, HRAS, CTAG1A, and NSG1 antibody detection in the early diagnosis of ESCC in a large sample of 569 cases of serum by constructing an ELISA method. The research cohort includes 409 A training set of 160 cases and a validation set of 160 cases with independent matching.

[0047] 1.1 Research object

[0048] A total of 569 serum samples were collected from Fujian Provincial Hospital from February 2016 to June 2018, including 179 early ESCC patients, 180 EBL patients, and 210 HC patients. All 179 patients with early ESCC were diagnosed on the basis of endoscopy combined with cytology or histopathology. They did not receive any anti-tumor treatment such as chemotherapy and radiotherapy. T...

Abstract

The invention provides a multiple autoantibody combined detection kit and application for diagnosing early esophageal squamous cell carcinoma. The kit comprises a solid-phase substrate and antigenic proteins coated on the solid-phase substrate, and the antigenic proteins are composed of TP53, HRAS, CTAG1A and NSG1. The present invention uses TP53, HRAS, CTAG1A and NSG1 as a combination for the early diagnosis of ESCC for the first time, which has high sensitivity and specificity, and helps to further improve the quality of serological screening for early diagnosis of ESCC, thereby promoting the cure of patients rate increase and survival rate prolongation.

Description

technical field [0001] The invention belongs to the technical field of medical diagnosis, and in particular relates to a multiple autoantibody combined detection kit for diagnosing early esophageal squamous cell carcinoma based on Luminex xMAP technology and its application. Background technique [0002] Esophageal squamous cell carcinoma (ESCC) is one of the most common upper gastrointestinal malignancies worldwide. As an area with a high incidence of esophageal cancer, China has the highest incidence rate of ESCC in the world, and ranks the fourth cause of cancer death (Ferlay J, Soerjomataram I, Dikshit R, Eser S, Mathers C, Rebelo M, et al. Cancer incidence and Mortality worldwide: Sources, methods and major patterns in GLOB ℃ AN2012. Int J Cancer 2015; 136(5):E359-86.). ESCC patients often have no specific clinical symptoms in the early stage and are difficult to be detected. It is difficult to find them, and the five-year survival rate is only 15-25% (PennathurA, Gibs...
