Herpes Simplex and Epstein-Barr Viruses Co-infection in Early-Stage Nasopharyngeal Carcinoma Treated with Concurrent Chemoradiation: Proteomic Analysis of Formalin-fixed Paraffin-embedded Samples from a Non-endemic Region

report our findings of prevalent viral infection-related proteins in nasopharyngeal carcinoma (NPC) via label-free quantitative (LFQ) proteomics in formalin-fixed paraffin-embedded (FFPE) samples. we retrieved clinical and follow up data from 82 consecutive NPC patients. One slice of FFPE sample with 10 microns was submitted to LFQ proteomic (LC-MS/MS). LC-MS/MS data were analyzed using Data Analysis 4.2 software. Proteins were identified using...
