The incidence of herpes zoster in patients with Hodgkin's disease. An analysis of prognostic factors.

The incidence of zoster in 717 patients with Hodgkin's disease was determined by a retrospective chart review. All patients had been treated and followed in one of six cancer centers. Prognostic factors that might predict the subsequent incidence of zoster were examined by univariate and multivariate analytic techniques. Intensity of treatment was a key factor in the incidence of zoster. Thirty-six months after initiation of treatment, patients receiving chemotherapy-radiation-chemotherapy had twice the attack rate (27.3%) of those receiving radiation alone (11.5%). The pediatric age group had a significantly higher attack rate (26.6%) than did adults (18.7%). Stage, histology, and laparotomy did not influence the incidence of zoster.
