OBJECTIVE: Psoriasis and psoriatic arthritis (PsA) are closely linked to cancer, as supported by the literature. Systemic treatments for psoriasis and PsA, namely non-biological disease-modifying anti-rheumatic drugs (DMARDs), have been associated with increased cancer risk in both conditions. New, more effective biological DMARDs (bDMARDs) do not seem to be associated with higher overall cancer risk compared to those not receiving bDMARDs, opening up possibilities for treating patients with previous or ongoing oncological disease alongside psoriasis and PsA. However, limited literature exists on treating PsA patients with cancer with bDMARDs. This study aims to assess the safety of secukinumab, a bDMARD, in patients with PsA and concurrent cancer. Here, we describe a case series of four patients with PsA treated with bDMARD secukinumab and review the literature on the subject.

CASE SERIES: We assessed the laboratory parameters and clinical characteristics of 4 patients with PsA treated with the bDMARD secukinumab and followed up until 30 months. Three patients had oncological disease in remission, while one had active neoplasia. No cancer progression was observed during the treatment of these patients with secukinumab.

CONCLUSIONS: In conclusion, our case series, consisting of four PsA patients with concurrent neoplasia treated with secukinumab, showed no evidence of cancer progression and represents the first case of PsA described in the literature treated during active oncological disease, lending support to the safety of secukinumab for the treatment of patients with PsA and concomitant neoplasia.
