Differentiated Thyroid Cancer; DTC - 1 識 註1 (2015ATA) Stratification of Sonographic Findings According to Probability of malignancy High suspicion [malignancy risk > 70-90%]: Solid hypoechoic nodule or a solid hypoechoic component in a partially cystic nodule with one or more of the following features: irregular margins (specifically defined as infiltrative, microlobulated, or spiculated), microcalcifications, taller than wide shape, disrupted rim calcifications with small extrusive hypoechoic soft tissue component, or evidence of extrathyroidal extension. A nodule demonstrating this ultrasound pattern is highly likely to be a papillary thyroid cancer. Intermediate suspicion [malignancy risk 10-20%]: Hypoechoic solid nodule with a smooth regular margin, without microcalcifications, extrathyroidal extension, or taller than wide shape Low suspicion [malignancy risk 5-10%]: Isoechoic or hyperechoic solid nodule, or partially cystic nodule with eccentric uniformly solid areas without microcalcifications, irregular margin or extrathyroidal extension, or taller than wide shape. Very low suspicion [malignancy risk < 3%]: Spongiform or partially cystic nodules without any of the sonographic features described in the low, intermediate or high suspicion patterns ; A spongiform appearance is defined as the aggregation of multiple microcystic components in more than 50% of the volume of the nodule Benign [malignancy risk < 1%]: Purely cystic nodules 377 甲狀腺癌診療指引共

Differentiated Thyroid Cancer; DTC - 4 識 註4 An active surveillance management can be considered as an alternative to immediate surgery in: Patients with very low risk tumors (e.g. papillary microcarcinomas without clinically evident metastases or local invasion, with no convincing cytologic or molecular (if performed) evidence of aggressive disease, not at a location adjacent to the trachea or on the dorsal surface of the lobe close to the recurrent laryngeal nerve, and with no signs of progression during follow-up.) 甲狀腺癌診療指引共381
Differentiated Thyroid Cancer; DTC - 5 識 註5 Initial Risk (of persistence/recurrence) Stratification System-1 (Modified from 2015 ATA Guidelines) Low Risk 1. Papillary Thyroid Cancer with all of the following (1)No local or distant metastases; (2)All macroscopic tumor has been resected (3)No tumor invasion of loco-regional tissues or structures (4) The tumor does not have aggressive histology (e.g., tall cell, hobnail variant, columnar cell carcinoma, diffuse sclerosing variant) (5) If 131I is given, there are no RAI avid metastatic foci outside the thyroid bed on the first post-treatment whole-body RAI scan (6)No vascular invasion (7)Clinical N0 or 5 pathologic N1 micrometastases (< 0.2 cm in largest dimension)* 2. Intrathyroidal, encapsulated follicular variant of papillary thyroid cancer* 3. Intrathyroidal, well differentiated follicular thyroid cancer with capsular invasion and no or minimal (< 4 foci) vascular invasion* 4. Intrathyroidal, papillary microcarcinoma, unifocal or multifocal, including V600E BRAF mutated (if known)*, without other worrisome features (e.g., aggressive histology, vascular invasion) 5. Intrathyroidal, papillary thyroid cancer, primary tumor 1-4 cm, V600E BRAF wild type, without other worrisome features (e.g., aggressive histology, vascular invasion) 382 甲狀腺癌診療指引共
Differentiated Thyroid Cancer; DTC - 5 識 註5 續 Initial Risk (of persistence/recurrence) Stratification System-2 (Modified from 2015 ATA Guidelines) Intermediate Risk 1. Microscopic invasion of tumor into the perithyroidal soft tissues 2. RAI avid metastatic foci in the neck on the first post-treatment whole-body RAI scan 3. Aggressive histology (e.g., tall cell, hobnail variant, columnar cell carcinoma, diffuse sclerosing variant) 4. Papillary thyroid cancer with vascular invasion 5. Clinical N1 or > 5 pathologic N1 with all involved lymph nodes < 3 cm in largest dimension* 6. Intrathyroid, papillary thyroid cancer, primary tumor 1-4 cm, V600E BRAF mutated (if known)* 7. Multifocal papillary microcarcinoma with extrathyroidal extension and V600E BRAF mutated (if known)* High Risk 1. Macroscopic invasion of tumor into the perithyroidal soft tissues (gross extrathyroidal extension), 2. Incomplete tumor resection 3. Distant metastases 4. Post-operative serum thyroglobulin suggestive of distant metastases 5. Pathologic N1 with any metastatic lymph node 3 cm in largest dimension* 6.
