Circulating tumor HPV DNA as a specific biomarker for cervical cancer.

Objective: The aim of this study was to determine whether circulating tumor human papillomavirus (HPV) DNA is a potential specific biomarker for cervical cancer (CC).

Methods: This retrospective matched study included 87 patients with cervical intraepithelial neoplasia (CIN), 29 CC patients (FIGO IA1-IVA) and 29 HPV-negative controls at Yuhuangding Hospital of Qingdao University (from July 2022 to September 2023). The digital droplet PCR (ddPCR) was used to detect and quantify ctHPV DNA in the plasma of patients with HPV16, 18, 33, 52, or 58-associated CC.

Expanding individualized therapeutic options via genoproteomics.

Clinical next-generation sequencing (NGS) tests have enabled treatment recommendations for cancer patients with driver gene mutations. Targeted therapy options for patients without driver gene mutations are currently unavailable. Herein, we performed NGS and proteomics tests on 169 formalin-fixed paraffin-embedded (FFPE) samples of non-small cell lung cancers (NSCLC, 65), colorectal cancers (CRC, 61), thyroid carcinomas (THCA, 14), gastric cancers (GC, 2), gastrointestinal stromal tumors (GIST, 11), and malignant melanomas (MM, 6).
