Este documento pretende ser una reflexión sobre las tendencias en la investigación del Virus del papiloma humano (VPH) en América Latina, en comparación con los países de ingresos altos. Materiales y métodos: se proporcionan respuestas sobre el VPH en términos de frecuencia, tendencias de investigación, programas de educación para pacientes y personal sanitario, y estrategias preventivas. Se realizó una revisión extensa de la investigación publicada y de los estudios presentados durante la I Reunión Sudamericana sobre el VPH. Resultados: el trabajo de investigación en el VPH se centra en estudios básicos y aplicados sobre el HVP y el cáncer cervical (CC). Existen limitaciones al desarrollo científico en nuestra región en comparación con los países de altos ingresos, y esto se refleja en la prevalencia de la enfermedad y las tasas de vacunación. Los programas de preve...

Context: Quality assurance in cervical cytology is based on the cyto-histological correlation that is performed in several countries even without standardized protocols. Aims: To evaluate the quality of the Pap smear with the Clinical and Laboratory Standards Institute (CLSI) EP12-A2 guideline in a Peruvian hospital. Settings and Design: This prospective study was carried out at tertiary care national hospital. Methods and Material: The 156 cyto-histological results were collected and coded according to the Bethesda 2014 and FIGO system. The evaluation with the CLSI EP12-A2 guide allowed estimating the performance and quality of the test. Statistical Analysis Used: We performed a descriptive analysis of the cytological and histological data and correlation with the weight Kappa test. From the calculation of the likelihood ratios, the post-test probability was estimated using Bayes' ...

Introduction: The follow-up of squamous intraepithelial lesions (SIL) allows us to understand their progression and regression, however squamous cell atypia (ASC) can generate confusing follow-up results. We aimed to describe the evolution of ASC and SIL during cyto-histopathological follow-up in a tertiary-care hospital. Materials and methods: we conducted a retrospective study during 2016 in 156 Papanicolaou test (PAP) results under three models: 1) with ≥1 PAP and biopsies, 2) 1 PAP followed by ≥1 biopsy, and 3) ≥1 PAP and a confirmatory biopsy. Progression was defined as ASCUS to low-grade SIL (LSIL) or higher, and LSIL to high-grade SIL (HSIL) or higher and regression as HSIL to LSIL or lower and LSIL to ASCUS or lower. Results: In PAP, 57 (36.5%) cases were ASC and in histopathology 56 (39.9%) cases of grade 1 cervical intraepithelial neoplasia. Twenty-nine (18.6%) results we...
