Thyroid Nodule Management: Primary Specialty
Endocrinologists are the primary specialists who manage thyroid nodules, working collaboratively with radiologists for imaging and surgeons for operative cases. 1
Primary Care Specialty
Endocrinologists serve as the principal specialists for thyroid nodule evaluation and management, as evidenced by their central role in developing multiple international guidelines for thyroid nodule care 1
Endocrinologists see the highest volume of thyroid nodule patients among specialists, averaging 89 patients per year compared to 30 for ENT physicians and 6 for general practitioners 2
The management of thyroid nodules requires endocrinology expertise because it involves both assessment of thyroid function (TSH, thyroid hormones) and malignancy risk stratification 1, 3
Multidisciplinary Collaboration Model
While endocrinologists lead thyroid nodule management, optimal care requires collaboration with specific specialists at defined decision points:
Radiology Integration
Radiologists perform and interpret thyroid ultrasound, which is the first-line diagnostic procedure for detecting and characterizing nodular thyroid disease 1
Radiologists frequently perform ultrasound-guided fine-needle aspiration (FNA), with 31.9% of FNAs performed by radiologists versus 56.6% by endocrinologists 4
The ACR (American College of Radiology) developed the TI-RADS system specifically to standardize thyroid nodule imaging assessment 1
Surgical Involvement
Thyroid surgeons (typically general surgeons or ENT surgeons with thyroid specialization) become involved when nodules require operative management 1
Surgical referral is indicated for: nodules with malignant or suspicious cytology, follicular neoplasms with suppressed TSH and "cold" appearance on scan, or symptomatic compressive nodules 1, 5
Surgeons see approximately 105 thyroid nodule patients annually, reflecting their role in definitive treatment rather than initial evaluation 2
Nuclear Medicine Participation
Nuclear medicine physicians contribute to thyroid nodule evaluation through radioiodine scanning when TSH is low or suppressed 5, 3
Nuclear medicine specialists also participate in radioiodine ablation therapy post-thyroidectomy for differentiated thyroid carcinoma 1
International Practice Patterns
The collaborative model between endocrinology, radiology, and surgery is consistent across international guidelines, though specific practice patterns vary by region 1, 6, 4
In France, the SFE-AFCE-SFMN consensus explicitly requires collaboration between endocrinologists, nuclear medicine physicians, and surgeons for optimal thyroid nodule management 6
Chinese guidelines similarly emphasize multidisciplinary participation, with 37 experts from interventional ultrasound, endocrinology, and thyroid surgery contributing to thermal ablation guidelines 1
Common Pitfall to Avoid
Do not assume general practitioners or primary care physicians routinely manage thyroid nodules independently—only 13.1% of general practitioners in one survey reported managing thyroid nodules, and those who do see far fewer cases (6 per year) than endocrinologists 2
Patients with thyroid nodules discovered incidentally should be referred to endocrinology for proper risk stratification using ultrasound features and FNA when indicated, rather than managed solely in primary care 7, 5
