Association Between HTLV-1 Infection and Nasopharyngeal Carcinoma: A Case-control Study
The northeast of Iran is one of the endemic regions of human T-cell lymphotropic virus type-1 (HTLV-1). This study aimed to evaluate the relationship between nasopharyngeal carcinoma and HTLV-1 infection in northeast Iran, an endemic area for HTLV-1.
In this case-control study, paraffin-embedded nasopharyngeal tissue samples of patients with definitive nasopharyngeal carcinoma were evaluated for the presence of the HTLV-1 genome by polymerase chain reaction retrospectively.
Thirty patients with nasopharyngeal carcinoma and 30 healthy people were evaluated. All participants were matched in terms of age and gender, and all were living in Mashhad. The HTLV-1 genome was detected in only one of the people in the healthy group.
The HTLV-1 infection and nasopharyngeal carcinoma did not correlate significantly.
