Herpes zoster complicating bortezomib therapy of relapsed/refractory indolent B-cell and mantle cell lymphoma: an analysis of two phase II trials. Issue 10 (October 2013) - Solh, Melhem
Abstract The incidence of herpes zoster (HZ) in patients with non-Hodgkin lymphoma (NHL) receiving bortezomib-based therapy has not been well studied. We reviewed data from two phase II trials in which bortezomib was administered to 236 patients, median age 65 years, with relapsed/refractory mantle cell or indolent NHL. HZ occurred in 24 patients (10.2%) overall, with a comparable incidence in NHL histologic subgroups. Median time to HZ was 39 (range, 11–206) days. In total, 71% of patients who developed HZ were aged ≥ 65 years, compared to 48% without HZ (p = 0.03). Patients with HZ were more likely to have had received ≥ 2 lines of therapy (63% vs. 47%, p = 0.16). Six (25%) of the patients who developed HZ had received purine analogs, compared with 34 (16%) patients without HZ (p = 0.27). As the occurrence of HZ may complicate the course of indolent or mantle cell NHL in patients receiving bortezomib-based therapies, these patients, especially the elderly, should be strongly considered for antiviral prophylaxis.
