Eligible patients have a confirmed PV diagnosis according to current criteria, have received at least one dose of Ropeginterferon, and have complete clinical and laboratory data available. The primary objective is to analyze the time course of hematologic response (complete or partial, CHR\u002FPR) according to ELN criteria, and to identify clinical and treatment-related factors associated with achieving and maintaining response. Secondary objectives include time to response, duration of response, progression-free survival, thromboembolic event rate, safety and tolerability, treatment discontinuation, dose modifications and adherence, normalization of hematologic parameters, and changes in JAK2 V617F allele burden.
