Antecedentes: El cáncer de laringe representa el 21.7% de las neoplasias malignas de vías aerodigestivas superiores. La prevalencia del virus del papiloma humano (VPH) en el cáncer de laringe oscila entre el 0 y el 80%.
MÉtodo: Se incluyeron 112 muestras de tejido laríngeo de pacientes con cáncer de laringe. Se amplificó el ADN y se analizó la presencia y el genotipo del VPH mediante hibridación reversa (INNO-LiPA). Se realizaron pruebas de ji cuadrada, Fisher y t de Student no pareada.
Resultados: Se incluyeron muestras de 107 hombres (95.5%) y 5 mujeres (4.5%), con una edad de 65.3 ± 10.1 años, con antecedente de tabaquismo 108 (96.4%), alcoholismo 9 (8.0%) y carcinoma epidermoide moderadamente diferenciado queratinizante 96 (85.7%). Se identificó VPH en 60 (53.5%), VPH-11 en 51 (45.5%), VPH-52 en 27 (24.1%), VPH-16 en 9 (8.0%), VPH-45 en 3 (2.6%) y coinfección por más de un genotipo en 31 (27.6%). No hubo diferencia entre pacientes con y sin infección por VPH en cuanto a edad, sexo, localización, diagnóstico histopatológico, tabaquismo ni alcoholismo (p > 0.05).
Conclusiones: La prevalencia de infección por VPH en el cáncer de laringe fue del 53.5%, con coinfección por más de un genotipo en el 27.6%. El genotipo más frecuente fue el VPH-11, tipo de bajo riesgo, seguido por el VPH-52, de alto riesgo oncogénico.
Background: Laryngeal cancer represents 21.7% of malignancies of the upper aerodigestive tract. The prevalence of the Human Papillomavirus (HPV) in laryngeal cancer ranges 0 to 80%.
Methods: We included 112 laryngeal tissue samples obtained from patients with laryngeal cancer. DNA was extracted and amplified by PCR. HPV presence and genotype were analyzed by the reverse hybridization INNO-LiPA assay. Chi-square, Fisher’s and unpaired Student t tests were used.
Results: Samples from 107 male (95.5%) and 5 female patients (4.5%) were evaluated, aged 65.3±10.1 years, 108 with smoking history (96.4%), 9 with alcoholism history (8.0%), and in 96 the histological diagnosis was moderately differentiated keratinizing squamous cell carcinoma (85.7%). HPV was detected in 60 samples (53.5%), HPV-11 in 51 (45.5%), HPV-52 in 27 (24.1%), HPV-16 in 9 (8.0%), HPV-45 in 3 (2.6%), and coinfection by more than one genotype in 31 (27.6%). There was no difference between patients with and without HPV infection with respect to age, sex, tumor location and histology, smoking and alcoholism history (p>0.05).
Conclusions: The prevalence of HPV infection in laryngeal cancer was 53.5% with coinfection with more than one genotype in 27.6%. The most frequent genotype was HPV-11, an oncogenic low-risk genotype, followed by HPV-52, a high-risk genotype.
