Fuzzy-DATA: A Strength- and Certainty-Calibrated Fuzzy TOPSIS Framework for Decision Support in Differentiated Thyroid Cancer

Öz

Clinical practice guidelines communicate both the direction and strength of recommendations, but these categorical labels do not directly resolve preference-sensitive choices for an individual patient. This study develops an interpretable fuzzy decision framework, Fuzzy-DATA, that incorporates recommendation strength, evidence certainty, patient-level applicability and contextual decision criteria within the 2025 American Thyroid Association management pathway for differentiated thyroid cancer. The framework uses a noncompensatory eligibility layer followed by a strength- and certainty-calibrated fuzzy Technique for Order Preference by Similarity to Ideal Solution (TOPSIS). Recommendation strength, certainty and applicability were represented by triangular fuzzy numbers and seven benefit-form criteria were used. Two synthetic showcases addressed a small low-risk papillary thyroid carcinoma and postoperative radioactive iodine selection for high-risk disease. Evaluation comprised one-way weight sensitivity, model ablation, Recommendation 15 scope-mapping stress tests, executable eligibility-gate tests and 30,000-iteration conditional numerical robustness simulation per showcase. In Showcase 1, active surveillance ranked first (closeness coefficient 0.709; conditional top-rank frequency 99.3%). Under the primary scope-qualified mapping, lobectomy overtook active surveillance near a guideline-concordance weight of 0.680, but this threshold changed under alternative scope mappings; unreliable follow-up excluded active surveillance. In Showcase 2, adjuvant iodine-131 at 100-150 millicuries ranked first (closeness coefficient 0.686; conditional top-rank frequency 92.7%). The leading alternative remained unchanged when the Dirichlet concentration varied from 50 to 300. The framework showed internally coherent and assumption-transparent behaviour under the illustrative inputs. The findings establish computational feasibility rather than clinical validity; multidisciplinary calibration and prospective validation are required.
