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

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|1-year CNS was defined as the probability of surviving 5 years given that the patient has survived 1 year. CF was defined as the proportion of patients with the same life expectancy as the general population. One-year NS and 5|1-year CNS were contrasted between 2013-2017 and 2003-2007, and CF between 2015 and 2005.

Results

For lesions up to 4 mm thick, 1-year NS reached a level > 98.0%. In 2013-2017, 5|1-year CNS was abov
