High Dose Rate Skin Brachytherapy: A Compassionate, Cost-Effective Alternative

AbstractBackground and purposeIn developing countries like Pakistan the cost effectiveness and patient convenience in any treatment modality is a question of major concern. The purpose of this study was two-fold; first to report our experience with a high-dose rate Iridium-192 surface mould brachytherapy of keloid scars after surgical excision, using different radiation treatment regimen and second to establish the most convenient and cost effective treatment protocol having no compromise on the treatment outcomes.Materials and methodsFrom January 2012 to April 2015 a total 51 patients with 65 keloid lesions underwent postoperative Iridium-192 high-dose rate surface mould brachytherapy. The dose regimen used was: 8 Gy in a single fraction, 10 Gy in a single fraction, 15 Gy in three fractions and 18 Gy in three fractions. The median follow-up period was 33 months (range 15–53 months).ResultsThe success rates were 57·2, 89·5, 85 and 89·5% for the treatment regimen of 8 Gy/F×1, 10 Gy/F×1, 5 Gy/F×3 and 6 Gy/F×3, respectively. Grade 2 or above radiation induced toxicity was not observed.FindingsThe results of this study show that a dose regimen of 10 Gy (biological effective dose=20 Gy) in a single fraction have comparable results with a dose regimen of 15 Gy in three fractions or 18 Gy in three fractions. 10 Gy in a single fraction is therefore the most convenient and cost effective dose regimen for the management of keloid scars in developing countries like Pakistan, while 8 Gy in a single fraction is considered suboptimal and discouraged in practice.

The Cost

Background: While evidence shows high-dose statins reduce cardiovascular events compared with moderate doses in individuals with acute coronary syndrome (ACS), many primary care trusts (PCT) advocate the use of generic simvastatin 40 mg/day for these patients. Methods and results: Data from 28 RCTs were synthesized using a mixed treatment comparison model. A Markov model was used to evaluate the cost-effectiveness of treatments taking into account adherence and the likely reduction in cost for atorvastatin when the patent expires. There is a clear dose–response: rosuvastatin 40 mg/day produces the greatest reduction in low-density lipoprotein cholesterol (56%) followed by atorvastatin 80 mg/day (52%), and simvastatin 40 mg/day (37%). Using a threshold of £20,000 per QALY, if adherence levels in general practice are similar to those observed in RCTs, all three higher dose statins would be considered cost-effective compared to simvastatin 40 mg/day. Using the net benefits of the treatments, rosuvastatin 40 mg/day is estimated to be the most cost-effective alternative. If the cost of atorvastatin reduces in line with that observed for simvastatin, atorvastatin 80 mg/day is estimated to be the most cost-effective alternative. Conclusion: Our analyses show that current PCT policies intended to minimize primary care drug acquisition costs result in suboptimal care.
