¹Mean reported instead of median.

²Only cases treated with curative intent included in analysis.

³Median overall survival (OS) [abdominoperineal resection (APR) vs wide excision].

⁴APR OS grouped as lymph node negative/lymph node positive.

⁵Melanoma specific survival.

⁶Mean OS of deceased patients only.

APR: Abdominoperineal resection; WE: Wide excision; mo: Month; OS: Overall survival.
