Urine sampling for HPV DNA detection has been proposed as an effective method for monitoring the impact of HPV vaccination programs; however, conflicting results have been reported. The goal of this study was to evaluate the performance of optimized urine HPV DNA testing in women aged 19 to 25 years. Optimization process included the use of first void urine, immediate mixing of urine with DNA preservative, and the concentration of all HPV DNA, including cell-free DNA fragments. Urine and cervical samples were collected from 535 young women attending cervical screening at health centers from two Colombian cities. HPV DNA detection and genotyping was performed using an HPV type-specific multiplex genotyping assay, which combines multiplex polymerase chain reaction with bead-based Luminex technology. Concordance between HPV DNA detection in urine and cervical samples was determined using kappa statistics and McNemar tests. The accuracy of HPV DNA testing in urine samples was evaluated measuring sensitivity and specificity using as reference the results obtained from cervical samples. Statistical analysis was performed using STATA11.2 software. The findings revealed an overall HPV prevalence of 60.00% in cervical samples and 64.72% in urine samples, HPV-16 being the most frequent HPV type detected in both specimens. Moreover, our results indicate that detection of HPV DNA in first void urine provides similar results to those obtained with cervical samples and can be used to monitor HPV vaccination trials and programs as evidenced by the substantial concordance found for the detection of the four vaccine types.Cancer Prev Res; 9(9); 766-71.

In 2012, Colombia launched human papillomavirus (HPV) vaccination program for girls ages 9 to 12, and in 2013, the target age was expanded to 9 to 17 years. Monitoring the changes of HPV infection prevalence among young women has been proposed as an endpoint for early assessment of HPV vaccination programs. However, the data on HPV prevalence in young ages are very limited. The purpose of this study was to determine the prevalence of HPV infection and the distribution of genotypes in a group of nonvaccinated women ages 18 to 25 years old in three Colombian cities as baseline for the monitoring of the HPV national vaccination program. A total of 1,782 sexually active women were included. Cervical smear samples were collected to perform the Pap smear and HPV DNA detection using a Linear Array HPV assay. Of the 1,782 specimens analyzed, 60.3% were positive for any HPV type; 42.2% were positive for high-risk HPV (HR-HVP) types, and 44.4% for low-risk HPV (LR-HPV) types. Multiple and single infections were identified in 37.1% and 23.2% of samples, respectively. HR-HPV types -16, -52, and -51 were the most predominant with proportions of 11.3%, 7.92%, and 7.9%, correspondingly. The prevalence for HR-HPV 16/18 was 14.4%. HR-HPV prevalence in women with abnormal cytology (75.16%) was higher than in women with normal cytology (38.6%). In conclusion, a high prevalence of HR-HPV was observed among younger women. This HPV type-specific prevalence baseline may be used to monitor postvaccination longitudinal changes and to determine its impact on HPV-related disease incidence in Colombia population. .

Colombia, tiene un riesgo intermedio a desarrollar  cáncer de mama  con una tasa de incidencia estandarizada por edad en de 44,1 por 100,000 mujeres. A pesar de que en el país se recomienda la tamización mediante mamografía, en mujeres de 50 a 69 años de edad y examen clínico de mama anual así como detección temprana para mujeres sintomáticas  independientemente de la edad, en Colombia no se no se ha podido reducir la mortalidad por esta causa. Múltiples causas parecen explicar este problema: baja participación en las actividades de tamización con mamografía por parte de la población objeto, baja calidad de la mamografía, y barreras  de acceso para el diagnóstico oportuno y el tratamiento integral. Frente a esta problemática el 03 de octubre fue aprobado en primer debate el proyecto de ley No 259 de 2019 Cámara Proyecto de Ley “Por medio de la cual se establecen medidas para la prevención, diagnóstico, tratamiento oportuno, rehabilitación, y cuidados paliativos del cáncer de mama y se dictan otras disposiciones”. A fin de revisar el soporte científico del contenido del proyecto de ley y aportar a su adecuada discusión, el Instituto Nacional de Cancerología INC realizó un foro el día 9 de diciembre del 2019. El propósito de este artículo es presentar el análisis de los puntos de mayor controversia desde una perspectiva científica, como base para la adecuada toma de decisiones en materia de políticas de salud pública.
