Reduction in cyclophosphamide cumulative dose and introduction of newer immunosuppressive drugs may reduce the malignant burden of systemic necrotising vasculitis (SNV).1 2 This study aimed to describe malignancies recorded in five randomised controlled trials in SNV conducted by the French Vasculitis Study Group and to identify predictive factors.
CHUSPAN, CHUSPAN 2, WEGENT, CORTAGE and MAINRITSAN trials evaluated different therapeutic strategies, summarised in online supplementary table S1, for the treatment of newly diagnosed or relapsing SNV. Informations regarding methods and references are provided in the online supplementary materials. The primary endpoint was the occurrence of malignancy.
A total of 733 patients included between 1993 and 2012 were pooled. Baseline characteristics of the population are summarised in table 1. During a 4485.9 person-years (PY) observation period, 39 (5.3%) patients developed malignancies (869.5 per 100 000 PY), including solid cancers in 34 (4.6%) cases (757.9 per 100000 PY) and haematological malignancies in 5 …
