Clinical Trial: Sentinel Lymph Node Detection in Gastric Cancer Using a Dual Tracer (Superparamagnetic Iron Oxide and Methylene Blue): A Prospective Study With Histological and OSNA Validation

U.S., Aug. 30 -- ClinicalTrials.gov registry received information related to the study (NCT07147452) titled 'Sentinel Lymph Node Detection in Gastric Cancer Using a Dual Tracer (Superparamagnetic Iron Oxide and Methylene Blue): A Prospective Study With Histological and OSNA Validation' on Aug. 22.

Brief Summary: Gastric cancer (GC) remains an oncological challenge, where lymph node involvement is a key prognostic factor. Sentinel lymph node (SLN) mapping may improve staging and reduce surgical morbidity. This study evaluated a dual-tracer technique - superparamagnetic iron oxide (SPIO) and methylene blue - for ex vivo SLN detection in GC, analysed the performance of one-step nucleic acid amplification (OSNA) versus conventional histology a...
