Problems solved by technology

Obviously, relying solely on clinical staging cannot accurately distinguish the risk of metastases in patients, so as to give targeted treatment, some patients may receive over-treatment, while others may receive insufficient treatment intensity

Embodiment Construction

[0021] The technical solution of the present invention will be further described below in combination with experiments.

[0022] Case screening:

[0023] The inventor selected 937 patients as samples of patients with non-metastatic locally advanced nasopharyngeal carcinoma, all of whom received radical radiotherapy. Among them, 56.6% of the patients (530 cases) also received concurrent chemotherapy based on cisplatin. After 68.1 months (quartile IQR 44.6 ~ 84.4), 209 of them had metastases during the follow-up period.

[0024] The inventors used the Affymetrix Human Gene 2.0ST expression profile chip to detect 24 cases of high risk of metastasis (no metastasis at first diagnosis, but distant metastasis occurred within 2 years after radical treatment) and 24 cases of low risk of metastasis (no metastasis at first diagnosis, and radical treatment). 137 differentially expressed genes were obtained by screening the first-diagnosed biopsy paraffin tissue specimens of nasopharynge...

Abstract

The invention discloses a marker for forecasting nasopharynx cancer transfer risk and an application thereof. The marker comprises ANXA1, CBR3, CLASP1, CXCL10, DCTN1, FNDC3B, LRIG1, FNDC3B, HDLBP, POLR2M, WSB2, WNK1, and YBX3. Molecular tags formed by 13 genetic expression formulas of the marker are capable of reflecting the biological specificity of a nasopharynx cancer patient, more accurately forecasting the transfer risk and prognosis of the nasopharynx cancer patient, and guiding clinical medication better. The forecasting efficiency to distance metastasis free survival is superior to thetraditional N-stage.

Description

technical field [0001] The present invention relates to prognostic markers of nasopharyngeal carcinoma, in particular to a group of markers for predicting the metastasis risk of nasopharyngeal carcinoma and its application. Background technique [0002] 40% of the world's nasopharyngeal carcinoma (NPC) occurs in China, with the highest incidence in southern China such as Guangdong Province. 70% of the patients are already in the middle and late stages when they go to the doctor, which seriously threatens the life and health of our people. In recent years, with the application of modern imaging technology and the advancement of intensity-modulated radiation therapy, the local control rate of nasopharyngeal carcinoma has been significantly improved, and distant metastasis has become the main mode of treatment failure. According to literature reports, the distant metastasis rate of nasopharyngeal carcinoma patients after initial radical treatment is as high as 30-40%, and metas...
