Background:
Surgical extension for treatment of patients with low-risk papillary thyroid carcinoma is still controversial. We undertook this study to assess if there is a difference in recurrence between patients undergoing total thyroidectomy plus adjuvant therapy and patients treated with only partial thyroidectomy.
Methods:
We conducted a longitudinal, observational, analytical study in patients with histopathological diagnosis of low-risk papillary thyroid carcinoma followed for at least 10 years. Patients were divided into two groups: Group 1: Patients treated with total thyroidectomy plus adjuvant therapy (TT) and Group 2: Patients treated with only partial thyroidectomy without adjuvant therapy (HT). Descriptive and inferential statistical methods were used.
Results:
AMES: 184 patients, recurrence in 5/23 HT and 7/161 TT (p = 0.0016); MACIS: 170 patients, recurrence in 5/24 HT and 5/146 TT (p = 0.0008); DeGroot: 92 patients, recurrence in 3/19 HT and 2/73 TT (p = 0.0254); TNM: 150 patients, recurrence in 5/22 HT and 7/128 TT (p = 0.0058). The time interval for local recurrences was higher in comparison to regional recurrences (p <0.05). In all classifications, recurrences occur mainly with regional metastatic disease (60%). Multifocality, bilateral disease and extracapsular disease showed no statistical difference. There was one incidental injury to a recurrent laryngeal nerve and this was repaired during the same surgical procedure. There was no morbidity due to hypoparathyroidism.
Conclusions:
Patients classified as low risk according to any of the studied classifications have a higher risk for recurrence when treated with hemithyroidectomy than when treated with total thyroidectomy plus adjuvant therapy.
