Auxiliary Diagnosis and Prognostic Value of Dehydrogenase/Reductase 2 (DHRS2) in Various Tumors.

Background: As the most convenient and commonly used for clinical diagnosis, cancer biomarker has been widely used in the auxiliary diagnosis of tumors, the observation of curative effect, the judgment of prognosis, and the monitoring of the disease.

Methods: Pan-cancer analysis was used to validate the value of Dehydrogenase/Reductase 2 (DHRS2) as a tumor prognostic marker in various tumors. The relationship of DHRS2 to TMB and MSI was used to explain the effect of DHRS2 on genomic instability. Online cbioportal was used to analyze DHRS2 mutations in tumors. Finally, 33 clinical tumor samples were collected in 2021 who were enrolled into the Affiliated Lianyun-gang Oriental Hospital of Xuzhou Medical University, to verify the expression and diagnostic prognostic value of DHRS2.

Results: The expression of DHRS2 was up-regulated in a variety of tumors and had adverse effects on the overall survival, disease-free interval, and progression-free interval of tumor patients. DHRS2 was associated with tumor genome instability, confirming that DHRS2 was correlated with tumorigenesis. In addition, DHRS2 had different mutation sites in various tumors. DHRS2 was up-regulated and was a poor prognosis biomarker in clinical tumor samples.

Conclusion: DHRS2 was aberrantly expressed in tumors and has diagnostic prognostic value.
