PRADO P, Yrneh Y et al. Comparison of the detection and typing of human papilloma virus in cytological samples vs. urine samples in female patients. Invest. clín [online]. 2017, vol.58, n.2, pp.107-118. ISSN 0535-5133.
Cervical cancer is the second most common cancer in women worldwide. Infection with high oncogenic risk Human Papillomavirus (HPV) is the main etiological factor of this malignancy. Viral identification is achieved by sensitive and specific molecular methods, such as polymerase chain reaction (PCR), which are generally used on cervical biopsies or swabs of biological material. Because of the complications and discomfort that taking these samples implies, studies are conducted with other samples obtained from less invasive methods, such as urine. Accordingly, detection and genotyping of HPV in endocervical swabs and urine were performed to compare results and to evaluate the effectiveness of using the latter samples. The genetic material was obtaining using the commercial kit Axygen. For viral detection and typing the conventional PCR technique was used. Positivity for HPV in cervical swabs was 68.6% and 62.9% in urine samples, similar values and comparable to previous studies. Likewise, the concordance obtained between the results of the samples used with respect to the identified viral types was moderate (k = 0.609), with high values of sensitivity and specificity of 83.3% and 81.8%, respectively, when urine samples were used. These results point to the possibility of developing an effective diagnosis for HPV using urine samples, because it would reduce the intervention of trained personnel, cost and discomfort for the patients.
