PURPOSE: Oral mucositis (OM) is a frequent side effect resulting from antineoplastic treatment and is described as an acute alteration characterized by ulcerative lesions, with the presence of a persistent chronic inflammatory infiltrate, erythema, and pain. AIMS: The purpose of the study was to evaluate the presence of the herpes simplex virus (HSV-1/2) in patients with squamous cell carcinoma of the head and neck region (SCC) and its influence on the aggravation of oral mucositis after radiotherapy or radio/chemotherapy treatment. METHODS: In this prospective cohort study, 91 patients were evaluated with regard to their serological status for IgG before treatment (initial time interval--TI) and for IgM before treatment (T1) and on the 30th day after the first day of radiotherapy application/radiation therapy (final time interval--TF), using immunoenzymatic assay (ELISA), and the results were correlated with the intensity of OM. RESULTS: The seroprevalence for IgG was 97.8 %. IgM (TI) was positive in 18.7% and IgM (TF) in 20.9% of patients. All the patients developed some degree of oral mucositis; however, there was statistically significant correlation between positivity for IgM and degree of severity of OM, irrespective of the type of treatment to which the patient was submitted. CONCLUSION: The reactivation of HSV-1/2 was shown to be relatively infrequent and there was no correlation between presence of the virus and aggravation of oral mucositis resulting from antineoplastic treatment.
