What is the study measuring?
-----------------
Primary Outcome Measures

| Outcome Measure | Measure Description | Time Frame |
| --- | --- | --- |
| Complete Response (CR) with Modified Visual RECIST tool | To assess the proportion of lesions achieving complete response (CR) as per MODIFIED VISUAL RECIST criteria | 12 months | 

Secondary Outcome Measures

| Outcome Measure | Measure Description | Time Frame |
| --- | --- | --- |
| SKINDEX-16 QoL Questionnaire | The QoL questionnaire will be scored according to the author's instructions. Change from baseline in score will be calculated. Descriptive statistics will be presented for actual score and change from baseline by timepoint, overall and by tumour type (BCC/SCC). | 6 months and 12 months | 
| Comfort of Treatment short questionnaire | Comfort of treatment assessed using a short questionnaire completed by subjects post treatment with Rhenium-SCT. The frequency (and percentage) of subjects reporting each option for each question will be presented. | 14 days | 
| cosmetic outcomes by Visual Analogue Scale | Cosmetic outcome assessed by subject and Clinician, using Visual Analogue Scale. Descriptive statistics will be presented overall and by tumour type (BCC or SCC). A mixed model will be fitted with Visual Analogue Scale as the outcome variable. Tumour type and tumour stage will be included as factors. Other relevant prognostic factors assessed at Baseline will be included. From the model the adjusted mean score will be obtained and presented with 95% confidence limits. Adjusted mean score will be estimated overall and by tumour type. | 12 months and 24 months |
