STK1p as a prognostic biomarker for overall survival in non-small-cell lung carcinoma, based on real-world data

Future Sci OA. 2020 Nov 23;7(3):FSO661. doi: 10.2144/fsoa-2020-0130.

Abstract

Aim: A prospective investigation of serum thymidine kinase 1 concentration (STK1p) was performed to evaluate its prognostic value in patients with non-small-cell lung carcinoma (NSCLCs).

Patients & methods: The STK1p values of 127 patients were determined by an enhanced chemiluminescent dot blot assay. The patients were recruited from March 2011 to December 2017.

Results: Kaplan-Meier plot showed that patients with elevated STK1p values had worse overall survival (OS), especially patients of early/middle stages. Multi-variable COX regression showed that STK1p value and combined treatment surgery + chemotherapy were independent prognostic factors for favorable OS.

Conclusion: STK1p is helpful in predicting OS of early/middle stages (I-IIIA) NSCLCs patients following a nonrandomized individual adapted treatment, but is may be not recommended in advanced stages (IIIB + IV) of NSCLCs.
