Clinical and Economic Impact of Herpes Zoster in Cancer Patients
Brazil150 participantsStarted 2019-09-01
Plain-language summary
Herpes zoster (HZ) is an important infectious complication among patients with cancer, particularly in the setting of treatment-related immunosuppression. This retrospective observational cohort study aimed to characterize the clinical profile of HZ episodes and estimate direct hospital costs associated with emergency department visits and hospitalizations in patients with active malignancy treated at a Brazilian tertiary cancer center. The study also explored associations between cancer characteristics, recent oncologic therapies, and clinical outcomes, including postherpetic neuralgia, recurrence, disease dissemination, and hospital costs. Findings are intended to support future budget impact and cost-effectiveness analyses of herpes zoster vaccination in oncology populations.

AI-rewrites the medical criteria so a patient or caregiver can understand them. Always confirm with the trial site.
Inclusion Criteria Adults (≥18 years). Active solid or hematologic malignancy. Evaluation at A.C. Camargo Cancer Center (São Paulo, Brazil) between September 2019 and December 2024.
Clinically confirmed episode of herpes zoster (initial episode or recurrence). Herpes zoster diagnosed based on a typical painful dermatomal rash with polymorphic lesions (macules, papules, vesicles, and crusts), either localized or disseminated.
Exclusion Criteria Age \<18 years. No evidence of active malignancy (complete remission or no oncologic treatment for at least one year).
Patients in whom herpes zoster was not confirmed after medical record review.
Questions worth asking your doctor
Bring these to your next appointment. They're a starting point for a shared conversation — not a sign you qualify or a recommendation to enrol.
1Based on my diagnosis and history, is this trial worth exploring for me — or is there a standard treatment we should try first?
2What does this trial's phase tell us about how much is already known about its safety and benefit?
3What would taking part actually involve for me — visits, tests, time, and travel?
4What are the known and possible risks or side effects I should weigh, and how would they be monitored?
5If this trial isn't the right fit, what other options or trials would you suggest I look into?
Generated to help you prepare — always confirm anything about your own eligibility and care with the study team and your doctor.
Questions for the trial coordinator
The trial coordinator is the person who runs the study day to day. These cover the practical side — logistics, costs, and what taking part would actually mean for your life. The study team confirms whether you meet the criteria; these are questions to ask, not a sign you qualify.
1What does taking part actually involve week to week — how many visits, where, and how long does each one take?
2What costs are covered by the study, and what might I have to pay for myself, including travel, parking, or time off work?
3What happens during screening, and what happens if the study team confirms I don't meet the criteria after those tests?
4Who pays for the scans, blood work, and other tests the trial requires — the study, my insurance, or me?
5How will being in the trial affect my regular care, and will my own doctor stay informed and involved?
6Can I leave the trial at any point if I change my mind, and what would happen to my care if I do?
A starting point for the conversation — always confirm anything about your own eligibility, costs, and care with the study team and your doctor.
