Trends in Survival and Cure Indicators of Thin and Thick Cutaneous Malignant Melanoma in Italy

Cancer Medicine, Volume 15, Issue 1, January 2026.
ABSTRACT Background In Italy, cure indicators of cutaneous malignant melanoma according to Breslow tumour thickness have never been assessed. Objectives To evaluate the time trend in 1‐year net survival (NS), 5|1‐year conditional NS (CNS) and cure fraction (CF). Methods Data from 10 cancer registries and 13,377 patients aged 15–74 years were used. Five|
