Results: Based on experience to date, the following are key issues that should be addressed when treatments are undertaken. Firstly, nuclear medicine specialists applying the paste should upskill in the diagnosis and management of NMSC. Secondly, practitioners applying the foil on the skin should practice the technique of foil application, which is generally the most challenging part of the procedure. Thirdly, all staff involved should be trained and understand the software used to calculate the administered dose, typically 50Gy as overtreatment or undertreatment can occur if there are dose calculation errors. Finally, all staff present (technologists, medical practitioners, nurses) must ensure that radiation safety procedures are carefully followed by all and there are sufficient staff to ensure that the patient dose not touch the radioactive paste until fully dry (typically ~5 minutes post application). 

Conclusions: SCT of NMSC is a promising treatment for many patients unsuited to surgery or external beam radiotherapy. Appropriate patient selection, upskilling of all staff involved, and careful attention to radiation safety precautions is essential to ensure optimal outcomes.
