Multiple Primary Melanoma Incidence Trends Over Five Decades: A Nationwide Population-Based Study.

ABSTRACT:

Background

Over the past decades, many regions have experienced a steady increase in the incidence of cutaneous melanoma. Here, we report on incidence trends for subsequent primary melanoma.

Methods

In this nationwide population-based study, patients diagnosed with a first primary cutaneous melanoma reported to the Swedish Cancer Registry were followed for up to 10 years for a diagnosis of subsequent primary melanoma. Patients were grouped with patients diagnosed with first melanoma in the same decade (1960s, 1970s, 1980s, 1990s, and 2000s, respectively). Frequencies, incidence rates (IRs), standardized incidence ratios (SIRs), and 95% confidence intervals (CIs) for second melanomas were calculated. All tests of statistical significance were 2-sided.
