National Epidemiology of Cutaneous Lymphomas

Rationale and Objective Primary cutaneous lymphomas are a rare and diverse group of cancers that start in the skin. While international data suggests an increase in cases since the 1970s, there is currently a lack of nationwide data in Italy regarding how common these diseases are and how they correlate with environmental or social factors.The main goal of this study is to create a national map of cutaneous lymphoma incidence and prevalence in Italy. Researchers want to identify if there are specific geographic areas with higher or lower numbers of cases and investigate potential links between the disease and environmental pollutants or other health conditions (comorbidities).Study Design This is a multicenter observational study that looks at both past and future data (retrospective and prospective). The study will involve approximately 1,000 patients across several Italian dermatology departments, with the IRCCS Azienda Ospedaliero-Universitaria di Bologna serving as the coordinating center.What the Study InvolvesData Collection: Researchers will review medical records from January 1, 2018, to December 31, 2022 (retrospective phase) and continue to collect data for patients enrolled over the next three years.Patient Participation: Patients will follow their standard clinical care paths. Information collected includes medical history, current and previous therapies, and laboratory results.Follow-up: Participants will be monitored for approximately two years to evaluate clinical outcomes and treatment responses.Expected Outcomes By analyzing this data, the study aims to improve clinical practice by providing a clearer understanding of how cutaneous lymphoma affects the Italian population based on age, sex, ethnicity, and location.
