Patient-based surgical outcome tool demonstrating alleviation of symptoms following parathyroidectomy in patients with primary hyperparathyroidism.
This study assessed the impact of parathyroidectomy on the preoperative symptoms of patients with primary hyperparathyroidism (1 degrees HPT) using a surgical outcome tool designed specifically for HPT. The multicenter nature of this study allowed us to validate further this disease-specific outcome tool. 1 degrees HPT patients from Canada, the United States, and Australia filled out the questionnaire preoperatively and postoperatively on day 7 and at 3 and 12 months. The symptoms recorded by the patients were expressed as parathyroidectomy assessment of symptoms (PAS) scores: the higher the score, the more symptomatic is the patient. Quality of Life (QOL) and self-rated health uni-scales were included. Altogether, 203 patients with 1 degrees HPT were enrolled; 27 from center A, 54 from center B, and 122 from center C; 58 nontoxic thyroid patients were enrolled for comparison. The comparison group had no significant change in their PAS scores throughout the study (scores 184, 215, 156, 186). All three centers demonstrated a significant reduction in symptoms following surgery. The median preoperative PAS score from center B patients was 282. Following surgery, PAS scores decreased significantly: 136, 58, 0 (p <0.05). Center C patients had a median preoperative PAS score of 344, decreasing postoperatively to 228 (p <0.05) and continuing to decrease to 190, then 180. Center A also demonstrated a significant reduction in symptoms at 3 months, from 510 preoperatively to 209 (p <0.001). Both QOL and self-rated health improved in the HPT patients, whereas no change was found in the comparison group following surgery. PAS scores are a reliable, disease-specific measure of symptoms seen with HPT. Parathyroidectomy significantly reduces these preoperative symptoms, and this change translated into an improved health-related QOL for the patients.
