Complication Rate, Cure Rate, Efficacy and Safety
Conditions
Brief summary
This study is a prospective, multicenter study designed to compare the efficacy and safety of surgical treatment versus ablation therapy (including radiofrequency ablation and microwave ablation) for patients with primary hyperparathyroidism (PHPT). The study will assess the impact of both treatment modalities on serum parathyroid hormone (iPTH) and calcium levels, clinical symptom improvement, bone mineral density enhancement, reduction in the incidence of urinary system stones, and postoperative complication rates. While surgical treatment has been the standard of care for PHPT, offering definitive cure, it carries inherent surgical risks and complications. Ablation therapy, as a minimally invasive approach, presents a novel alternative with reduced trauma and fewer complications. The outcomes of this study will inform clinical decision-making and potentially optimize treatment strategies for patients with PHPT.
Interventions
Thermal ablation is a minimally invasive procedure used to treat primary hyperparathyroidism, a condition where one or more of the parathyroid glands produce excessive amounts of parathyroid hormone (PTH). The treatment involves using heat to destroy the overactive parathyroid tissue. This can be done through various methods such as radiofrequency ablation (RFA) and microwave ablation(MWA).
Parathyroidectomy is a surgical procedure to remove one or more of the parathyroid glands in cases of hyperparathyroidism.

Eligibility
Inclusion criteria
* Symptomatic patients with primary hyperparathyroidism, such as those with symptoms in any system including the kidneys, bones, gastrointestinal tract, psychoneurological system, or those with atypical symptoms such as muscle weakness, dysfunction, and sleep disorders. * Asymptomatic PHPT patients with any of the following conditions: ① Serum calcium is higher than the upper limit of the normal value by 1 mg/dL (0.25 mmol/L); ② There is objective evidence of renal involvement, including asymptomatic kidney stones, nephrocalcinosis, hypercalciuria (24 - hour urinary calcium level \> 400 mg/dL) on renal imaging, or impaired renal function (glomerular filtration rate \< 60 mL/min); ③ There is evidence of osteoporosis (bone mineral density decreased by 2.5 standard deviations at any site) and/or radiographic evidence of fragility fractures. ④ Age \< 50 years ⑤ The patient cannot accept routine follow - up observation. * Imaging examination shows that at least one parathyroid gland is enlarged.
Exclusion criteria
* diagnosis of secondary or tertiary HPT * severe coagulation disorder * severe cardiopulmonary insufficiency
Design outcomes
Primary
| Measure | Time frame | Description |
|---|---|---|
| cure rate | 6 months after surgery or ablation | The cure rate is the probability that postoperative levels of parathyroid hormone (PTH) and blood calcium reach the target values. |
Secondary
| Measure | Time frame | Description |
|---|---|---|
| complication rate | within 30 days after surgery or ablation | The incidence rate of complications refers to the proportion of patients who experience complications after a surgical procedure within a certain period. |
| symptom remission rate | 1 year after treatment initiation | The symptom remission rate refers to the proportion of the number of patients whose symptoms have been alleviated to the total number of patients treated in the treatment of primary hyperparathyroidism, either by surgery or ablation. |
| Normalization Probability of Serum Calcium and Phosphorus after Ablation or Surgery | 6 months post-treatment | The probability of normal serum calcium and serum phosphorus levels after ablation or surgical treatment for primary hyperparathyroidism is defined as the proportion of patients in whom the levels of blood calcium and blood phosphorus return to the normal physiological range among all the patients who have received either ablation or surgical procedures for this condition. |
| Bone mineral density change | 2 years | Bone mineral density change after treatment is defined as the alteration in bone density measured by DEXA in patients with primary hyperparathyroidism after surgery or ablation. |

| Evaluation of the Learning Curve for Surgical and Ablation Procedures in Treating Primary Hyperparathyroidism: Incorporating Key Performance Indicators and Patient Cure Outcomes | through study completion, an average of 2 year | The learning curve for surgical or ablation procedures will be evaluated by tracking and analyzing key performance indicators, with patient cure outcomes also taken into account. These indicators encompass the time taken from the start of the procedure until its completion (operation time). Additionally, the rate of occurrence of immediate and short-term post-operative complications (like bleeding, nerve injury) is considered. Patient cure status, such as complete remission of related symptoms, normalization of relevant physiological indicators, and long-term disease-free survival, will be meticulously assessed to comprehensively evaluate the effectiveness and learning the effectiveness and learning curve of these procedures. |
| Cosmetology Scoring(Scar Cosmesis Assessment and Rating Scale) | at 3 months, 6 months, and 1 year post-procedure | The Scar Cosmesis Assessment and Rating Scale (SCAR) will be utilized to evaluate the cosmetic outcome following surgical or ablation treatment for primary hyperparathyroidism. The observer part of the SCAR assesses six aspects: scar spread, erythema, pigmentation abnormality, surgical marks or suture tracks, hypertrophy/atrophy, and overall impression. The patient part includes two simple questions about patient satisfaction with the scar and the degree of itching. The scale has a minimum value of 0, representing the least severe scar with the best cosmetic appearance, and a maximum value of 15, signifying the most severe scar with the poorest cosmetic result. Higher scores on this scale indicate a worse cosmetic outcome. |
