Standardised skin response definitions (utilising the modified Severity Weighted Assessment Tool score) [1].

Response	Definition
Complete response	100% clearance of skin lesions.
Partial response	50–99% clearance of skin disease from baseline without new tumours (T3) in patients with T1, T2, or T4 only skin disease.
Stable disease	<25% increase to <50% clearance in skin disease from baseline without new tumours (T3) in patients with T1, T2, or T4 only skin disease.
Progressive disease	≥25% increase in skin disease from baseline, or New tumours (T3) in patients with T1, T2, or T4 only skin disease, or Loss of response: in those with complete or partial response, increase of skin score of greater than the sum of nadir plus 50% baseline score.
Relapse	Any disease recurrence in those with complete response.
