Malignancy Predictors, Bethesda and TI-RADS Scores Correlated With Final Histopathology in Thyroid Diseases

Correlation of Malignancy Predictors, Bethesda (I-VI) and TI-RADS Scores (I-V) With Final Histopathology in Patients Undergoing Total Thyroidectomy 34 Years After Chernobyl Disaster: Multi-centric Trial

Malignancy risk factors: 1. Demographics (Age and gender-Male/Female), 2. Smoking history (Yes/No, duration and number/day), 3. Iodine-deficient diet (Yes/No), 4. Born at an endemic area (Yes/No), 5. Presence in an endemic area (Yes/No), 6. Radiation exposure (Yes/No), 7. Radiation treatment during childhood (Yes/No), 8. Head and neck carcinoma (Yes/No), 9. Other carcinoma history (Yes/No, if yes specify.........) 10. Family history of thyroid disease (Yes/No), 11. Family history of other carcinomas (Yes/No), 12. Personal history of thyroid carcinoma/surgery (Yes/No, if yes, pathology……..), 13. Personal history of other carcinomas (e.g. colonic polyps? breast disease?......) 14. Genetic disorders (Yes/No), 15. Obesity (Body mass index - ? kg/m2), 16. Diabetes mellitus (Yes/No) should be evaluated for each patient before surgery- The number of risk factors will be compared with malignancy rate found at final histopathology report.

Bethesda score-FNA cytology report- as I, II, III, IV, V or VI. Cytology report will be compared with final histology report for each patient for malşgnancy rate and multifocality I. Nondiagnostic or unsatisfactory, II. Benign, III. Atypia of undetermined significance (AUS) or follicular lesion of undetermined significance (FLUS), IV. Follicular neoplasm or suspicious for a follicular neoplasm-Preoperative cytology category will be compared with postoperative final histopathology report for malignancy rate, multifocality and cases with cytology-histopathology discrepancy will be evaluated further for biopsy techniques and cytology mis-interpretations.
V. Suspicious for malignancy, VI. Malignant.

TI-RADS score-Ultrasound evaluation of thyroid nodues- as I, II, III, IV or V. TI-RADS scores will be compared with final histopathology report to see malignancy rates and accuracy of TI-RADS.
TI-RADS 1: Normal thyroid gland. No focal lesion. TI-RADS 2: Benign nodules. Noticeably benign pattern (0% risk of malignancy) TI-RADS 3: Probably benign nodules (<5% risk of malignancy)
TI-RADS 4:
4a - Undetermined nodules (5-10% risk of malignancy) Score of 1.
4b - Suspicious nodules (10-50% risk of malignancy) Score of 2.
4c - Highly suspicious nodules (50-85% risk of malignancy) Score of 3-4 TI-RADS 5: Probably malignant nodules (>85% risk of malignancy) Score of 5 or higher TI-RADS 6: Biopsy-proven malignancy

Final histopathology report-After surgery (all patients should have a final histopathology report after total thyroidectomy operation). Final histology report will be correlated to Malignancy risk factors (number), Bethesda category (accuracy, false negativity/positivity) and TI-RADS (accuracy, false negativity/positivity)

All Excel documents will be available (Patient initials and medical record numbers shaded XX). Demographics, BMI, malignancy risk factors, Bethesda and TI-RADS scores and final histopathology reports

Patients with morbid obesity who were eligible for and willing to have bariatric surgery performed

Age and BMI matched patients with morbid obesity who either were not eligible for or were not willing to have bariatric surgery performed - no sufficient number of matched patients has completed the study; the arm of obese patients not treated with bariatric surgery has been discarded for the purpose of the analyses
