Prognostic subclassifications of T1 cutaneous melanomas based on ulceration, tumour thickness and Clark’s level of invasion: results of a population-based study from the Swedish Melanoma Register

Abstract: SummaryBackground Survival and prognostic factors for thin melanomas have been studied relatively little in population-based settings. This patient group accounts for the majority of melanomas diagnosed in western countries today, and better prognostic information is needed. Objectives The aim of this study was to use established prognostic factors such as ulceration, tumour thickness and Clark's level of invasion for risk stratification of T1 cutaneous melanoma. Methods From 1990 to 2008, the Swedish Melanoma… Show more

“…Tumour thickness was analysed as a categorical variable grouped according to the American Joint Commission on Cancer (AJCC) 2002 classification (16), but with an additional subdivision of T1 into three previously used groups (<0.5 mm, 0.5-0.8 mm and 0.81-1.0 mm) (12). Tumour sites were divided into three groups (head/neck, trunk and extremities).…”

“…Other studies have previously found such disparities and the most probable explanation is selection bias. The AJCC results are based on a selected data set of patients, probably due to inclusion of patients referred to the institution for metastatic disease and not primarily treated at that institution (12,21) (22). Unfortunately it is too early to assess the impact of these treatments with the present data.…”

“…Ulceration of the primary melanoma has also been identified in some large series as an important prognostic determinant [22, 23] but none of our patients presented with ulceration so we could not analyze this factor. Likewise, because of a low number of prepubertal patients in our cohort, we could not analyze features specific to this population.…”

“…PLG patients provided written, informed consent under an Institutional Review Board-approved protocol. A PUBMED search yielded three non-US studies, two population/registry-based and one set in a single institution, that reported five- and/or ten-year CMD rates for patients in the four subgroups of thin melanomas: Sweden (Lyth et al, 2013), Queensland (Green et al, 2012) and Germany (Leiter et al, 2004). …”
