Next‑generation sequencing failure rates in rare tumors: A real‑world single‑institution analysis.

Reported next-generation sequencing (NGS) failure rates vary widely and are primarily based on studies of common tumor types. The present study aimed to estimate NGS failure rates in rare tumors and their association with preanalytical variables and sequencing methods in a single institution. Patients with sarcomas, rare carcinomas, and rare melanomas who underwent NGS between January 2022 and October 2023 were eligible for participation in the present study.

Serum and synovial fluid levels of interleukin-17 in correlation with disease activity in patients with RA.

The aim of this study was to evaluate serum and synovial levels of IL-17A by ELISA in rheumatoid arthritis (RA) and find out the correlations between IL-17A levels and various clinical, laboratory parameters and RA disease activity and severity indices. Group I consists of 30 adult active RA patients fulfilling the ARA 1987 revised criteria, with knee effusion and receiving basic therapy, and with a mean age of 41.47±11.
