This study explores the use of NLS (Non-Linear System) technology for evaluating lymph nodes in oncology patients. NLS helps identify enlarged, inflamed, hyperplastic, and metastatic lymph nodes by analyzing their size, structure, chromogeneity, vascular patterns, and relationship with surrounding tissues. Advanced techniques such as 3D NLS-graphy, ultramicroscanning, and spectral-entropic analysis (SEA) improve the detection of deep lymph nodes that cannot be assessed through palpation. The method also aids in differentiating inflammatory lymphadenopathy from malignant involvement and allows dynamic monitoring of treatment response. According to the authors, NLS demonstrated high diagnostic specificity and provided valuable information for cancer staging and treatment planning.
