This study aimed to revisit the current age criterion of 50 years for surgical candidacy in patients diagnosed with asymptomatic primary hyperparathyroidism (PHPT). A Markov model was constructed based on past publications to compare two potential treatment algorithms, parathyroidectomy (PTX) and observation. The results suggest that PTX is advantageous for asymptomatic PHPT patients older than 50 years, indicating a need for revisiting the current guidelines for surgical treatment in young asymptomatic PHPT patients.
ObjectiveTo revisit the current age criterion (50 years) for surgical candidacy in patients diagnosed with asymptomatic primary hyperparathyroidism (PHPT). Study DesignA predictive model relying on past publications using the electronic databases PubMed, Embase, Medline, and Google Scholar. SettingHypothetical large cohort. MethodsA Markov model was constructed, based on relevant literature, to compare 2 potential treatment algorithms for asymptomatic PHPT patients, parathyroidectomy (PTX), and observation. The various potential health states were characterized for the 2 treatment options and included potential surgical complications, end-organ deterioration, and death. A 1-way sensitivity analysis was performed to calculate the quality-adjusted life year (QALY) gains of both strategies. A Monte-Carlo simulation for 30,000 subjects was performed and cycled per annum. ResultsOn the basis of the model's assumptions, the QALY value for the PTX strategy was 19.17 versus 17.82 for the observation strategy. The incremental QALY gains for various ages according to the sensitivity analyses for PTX in comparison to observation were: 2.84 QALY for 40-year-old patients, 2.2 QALY for 50-year-old patients, 1.81 QALY for 55-year-old patients, 1.35 QALY for 60-year-old patients, and 0.86 QALY for 65-year-old patients. The incremental QALY is below 0.5 after the age of 75 years. ConclusionThis study found PTX to be advantageous for asymptomatic PHPT patients older than the current age criterion of 50 years. The calculated QALY gains support a surgical approach for medically fit patients in their 50s. The current guidelines for the surgical treatment of young asymptomatic PHPT patients should be revisited by the next steering committee.
