Abstract
Background
This cross-sectional study compared patient-reported outcomes of low-risk papillary thyroid carcinoma (PTC, T1N0M0) between patients who underwent active surveillance (AS) and those who received immediate surgery,
Methods
Using the State-Trait Anxiety Inventory, Short-Form 36 version 2, and a visual analog scale for neck symptoms, 249 patients under AS and 32 patients underwent immediate surgery were compared. To match the difference in time from the onset of treatment to the survey, we conducted propensity score matching. We also investigated factors affecting anxiety in patients under AS in multiple linear regression analysis.
Results
In the entire group, patients under AS had significantly longer time from the onset to the survey than patients underwent immediate surgery (7.9 vs. 4.0 years). After matching, AS group showed significantly better trait anxiety and mental component summary (MCS) compared to surgery group, while surgery group showed better role-social component summary. AS group also had significantly better MCS than the Japanese norm-based score. Surgery group displayed worse neck symptoms than AS group. Among AS group, trait anxiety and time from the onset were significant predictors of state anxiety. Compared with the group with < 5 years since starting AS, the group with ≥ 5 years of follow-up showed a significantly better state anxiety only in patients with better trait anxiety.
Conclusions
Low-risk PTC patients under AS showed better trait anxiety and mental health than surgery group. After a certain period, the anxiety of patients under AS seems to be improved, especially in patients with better trait anxiety.
