Summary
Most papillary and follicular thyroid carcinoma patients in Australasia are low-risk. This suggests less aggressive surgical treatment may be suitable for many, reducing complications from total thyroidectomy.
Area of Science:
- Endocrinology
- Surgical Oncology
- Thyroid Cancer Research
Background:
- Total thyroidectomy is standard for papillary and follicular thyroid carcinoma in Australasia.
- Clinicopathological factors stratify patients into risk groups.
- Low-risk patients may benefit from less extensive surgery.
Purpose of the Study:
- To assess the proportion of low-risk patients with thyroid cancer.
- To identify candidates for less aggressive surgical approaches.
Main Methods:
- Analysis of 175 previously untreated thyroid carcinoma patients over 10 years.
- Application of Mayo Clinic, Lahey Clinic, and Memorial Hospital prognostic scoring systems.
- Evaluation of complication rates following total thyroidectomy.
Main Results:
- 75-81% of patients were classified as low-risk across different scoring systems.
- Tumor size < 4 cm in 81%; 41% were ≤ 40 years old.
- Total thyroidectomy had low complication rates (1% nerve palsy, 1.9% hypoparathyroidism); no permanent complications in the low-risk group.
Conclusions:
- The majority of thyroid cancer patients treated were low-risk.
- Less aggressive surgical options could be considered for these patients.
- This study supports tailored treatment strategies for thyroid cancer.
