Abstract

The invention provides an HNC (Head and Neck Cancer) prognosis biomarker based on a lymph node microbial flora and application of the HNC prognosis biomarker, and belongs to the technical field of disease prognosis and molecular biology. According to the invention, the 16S ribosomal RNA gene of the lymph node microbial flora of an HNC patient is subjected to high-throughput sequencing, so that it is proved that different species exist in flora species of metastatic lymph nodes and non-metastatic lymph nodes in the HNC patient; furthermore, through a microbial flora symbiotic relationship network, it is found that the flora interrelation between the species of the metastatic lymph node and the species of the non-metastatic lymph node of the HNC patient is also different at the genus level; the result discovers the characteristics of the microbiome of the metastatic lymph node and the non-metastatic lymph node of the HNC patient for the first time; and meanwhile, it is known by analysis that the flora difference characteristics (diversity index values and relative abundance of different species) have a good prediction effect on the lifetime (total lifetime and three-year lifetime) of the HNC patient, so that the invention has a good practical application value.

Description

technical field [0001] The invention belongs to the technical field of disease prognosis and molecular biology, and specifically relates to a head and neck cancer prognosis biomarker based on lymph node microbial flora and its application. Background technique [0002] The information disclosed in this background section is only intended to increase the understanding of the general background of the present invention, and is not necessarily taken as an acknowledgment or any form of suggestion that the information constitutes the prior art already known to those skilled in the art. [0003] Head and Neck Cancer (HNC) refers to malignant tumors that occur in the head and neck, including the oral cavity, oropharynx, nasopharynx, and larynx. There are about 650,000 new cases of head and neck cancer each year worldwide. One of the more common malignant tumors has seriously threatened human life and health. The scientific community is still not completely clear about the cause of...
