Quality of Life in Patients with Low-Risk Papillary Thyroid Microcarcinoma: Active Surveillance Versus Immediate Surgery

Abstract

This study aimed to compare the quality of life (QoL) and psychological issues of patients with papillary thyroid microcarcinoma (PMC) who were under active surveillance (AS) and those who underwent immediate surgery (OP). This was a cross-sectional study conducted on 347 patients with low-risk PMC who were under AS (n = 298) or who underwent OP (n = 49). They were asked to complete two questionnaires (thyroid cancer-specific health-related QoL [THYCA-QoL] and the Hospital Anxiety and Depression Scale [HADS]). The results between the AS and OP groups were compared. The mean ages of patients in the AS and OP groups were 58.6±12.5 and 58.4±13.1 years (P =.94), respectively, and the male ratios were 34/298 (11%) and 2/49 (4.1%) (P =.14), respectively. The median follow-up periods from diagnosis in the AS and OP groups were 56.5 months (interquartile range [IQR], 32 to 88 months) and 84 months (IQR, 64 to 130 months) (P<.001), respectively. In the THYCA-QoL questionnaire, the OP group had more complaints about "voice" (P<.001), "psychological" (P =.025), "problems with scar" (P<.001), and "gained weight" (P =.047) than the AS group. Other scales of the THYCA-QoL were comparable in the two groups. In the HADS questionnaire, the AS group had significantly better anxiety (P =.020), depression (P =.027), and total scores (P =.014) than the OP group. PMC patients in the OP group had more complaints and were more anxious and depressed than the AS group. These findings suggest that AS is a reasonable alternative to surgery for patients with low-risk PMC from the point of view of QoL and psychology. AS = active surveillance; CI = confidence interval; HADS = Hospital Anxiety and Depression Scale; LT4 = levothyroxine; OP = immediate surgery; PMC = papillary microcarcinoma; PTC = papillary thyroid carcinoma; QoL = quality of life; STAI = State-Trait Anxiety Inventory; THYCA-QoL = thyroid cancer-specific health-related quality of life; TSH = thyrotropin.
