Analysis of Risk Factors for Postherpetic Neuralgia in Patients With Postmalignancy Herpes Zoster.

Background: The high risk of developing postherpetic neuralgia (PHN) is associated with severe immunosuppressive diseases. A malignancy itself, as well as surgery, radiotherapy, and other treatments, can lead to changes in the immune status of the body and predispose patients with a malignancy to PHN.

Objective: To investigate the risk factors of postherpetic neuralgia in herpes zoster (HZ) after a malignant tumor and to provide better preventive strategies for clinical practice.
