RECRUITINGprevalence of cutaneous T-cell lymphoma (CTCL) variants
The prevalence and the exact binomial 95% CI will be presented.
Time frame: October 2033
survival among the various subtypes of CTCL
To compare survival among the various subtypes of CTCL, the survival rate will be reported as deaths per 100 person-years; the start date of follow-up will be the diagnosis of the disease. The groups will be compared using the log-rank test and survival will be described using Kaplan-Meier curves.
Time frame: October 2033
Association between clinical, histopathological and immunophenotypic characteristics of patients with cutaneous T-cell lymphoma and overall survival
A Cox model will be used to derive the hazard ratio (HR) and relative 95% CI. Harrell's c statistic will be calculated for the model's ability to discriminate. Estimates will be adjusted as far as possible for potential confounding factors.
Time frame: October 2033
dermatoscopic features of cutaneous T-cell lymphomas
Descriptive statistics will be calculated for each type of cutaneous lymphoma.
