RESUMO

RESUMEN Estudio transversal que determinó la frecuencia y genotipos del virus del papiloma humano de alto riesgo (VPH-AR) a través de la técnica de autotoma en un grupo de universitarias de Lima. Participaron 221 estudiantes y se detectó el ADN del VPH-AR con el método de reacción en cadena de la polimerasa (PCR). La frecuencia del VPH-AR en las participantes fue de 43,4%; de este grupo se encontraron los genotipos VPH 16 en el 15,6% y VPH 18 en el 4,2% y otros VPH-AR en el 80,2%. Se concluye que la frecuencia del VPH-AR es mayor en el grupo de universitarias de este estudio en comparación a investigaciones nacionales previas.


ABSTRACT Cross-sectional study that determined the frequency and the genotypes of the (HR-HPV) high-risk human papillomavirus through the self-collection technique in a group of college students of Lima. Two hundred twenty-one (221) students participated and the DNA of the HR-HPV was detected with polymerase chain reaction (PCR). The frequency of HR-HPV in participants was 43.4%; of this group, genotype HPV 16 was present in 15.6%, HPV 18 in 4.2%, and another HR-HPV in 80.2%. We can conclude that the frequency of HR-HPV is greater in the group of college students of this study in comparison with previous national investigations.

RESUMO

Objetivo: El objetivo del estudio fue determinar si la Biopsia Core por aspiración con aguja fina es un método seguro para realizar diagnóstico de cáncer de mama en mujeres con tumoración mamaria palpable. Materiales y métodos: Se realizó un estudio prospectivo, analítico y de corte transversal en el área de Prevención del cáncer, constituida por 105 mujeres con tumor palpable en mama que acudieron al Departamento de Prevención y diagnóstico de cáncer del Instituto Nacional de Enfermedades Neoplásicas (INEN) durante el periodo del 01 de julio del 2014 hasta el 30 de abril del 2015. La muestra en estudio fue seleccionada mediante el muestreo no probabilístico y en base a criterios de inclusión y exclusión. Resultados: La edad promedio fue significativamente mayor en el grupo con resultado patológico maligno (51.21 años), se observa que a medida que la edad aumenta, las patologías benignas van disminuyendo en frecuencia en comparación con las patologías malignas que aumentan en frecuencia. Se observa del total de 105 mujeres con tumor palpable; el 35.2 % fueron patología maligna y 64.8 % correspondieron a patología benigna. La sensibilidad, especificidad, valor predictivo positivo, valor predictivo negativo se estiman en 94 %, 96 %, 94 % y 96 % respectivamente; la seguridad diagnostica de la BAAF fue de 90.3 %. Conclusiones: La biopsia por aspiración con aguja fina es un método de diagnóstico seguro para detección de cáncer de mama en mujeres con tumoración mamaria palpable.


Objective: The objective of the study was to determine if fine-needle aspiration biopsy is a safe method to diagnose breast cancer in women with a palpable breast tumor. Materials and methods: A prospective, analytical and cross-sectional study on cancer prevention conducted in 105 women with a palpable breast tumor who went to the Department of Cancer Prevention and Diagnosis of the Instituto Nacional de Enfermedades Neoplásicas (INEN) from July 1, 2014 to April 30, 2015. The study sample was selected through non-probabilistic sampling, and based on inclusion and exclusion criteria. Results: The average age was significantly higher in the group with a malignant pathological result (51.21 years). It was observed that, as age increases, benign pathologies decrease in frequency in comparison with malignant pathologies that increase in frequency. It was also observed that out of the total of 105 women with a palpable tumor, 35.2% had a malignant pathology and 64.8% had a benign pathology. Sensitivity, specificity, positive predictive value, and negative predictive value were estimated at 94%, 96%, 94% and 96%, respectively. The diagnostic safety of the FNAB was 90.3% Conclusions: Fine-needle aspiration biopsy is a safe diagnostic method for the detection of breast cancer in women with palpable breast tumors.

RESUMO

BACKGROUND: An ecological correlation between invasive cervical cancer incidence and burden of soil-transmitted helminths (STH) is hypothesized to explain the excess in detectable human papillomavirus (HPV) infection in Latin America, via a global T-helper type 2 (Th2)-biased mucosal immune response secondary to STH infection. METHODS: The association between current STH infection and HPV prevalence was compared in regions of Peru where STH is or is not endemic. Adjusted prevalence ratios (PRs) with robust variance were estimated as an effect measure of STH infection on HPV prevalence in each study site. Soluble immune marker profiles in STH-infected and STH-uninfected women were compared using Spearman rank correlation with the Sidak correction. RESULTS: Among women in the helminth-endemic region of the Peruvian Amazon, those with STH infection women had a 60% higher prevalence of HPV, compared with those without STH infection (PR, 1.6; 95% confidence interval, 1.0-2.7). Non-STH parasitic/protozoal infections in the non-STH-endemic population of Peru were not associated with HPV prevalence. In Iquitos, A Th2 immune profile was observed in cervical fluid from helminth-infected women but not helminth-uninfected women. CONCLUSIONS: A proportion of the increased HPV prevalence at older ages observed in Latin America may be due to a population-level difference in the efficiency of immunological control of HPV across the lifespan due to endemic STH infection.

RESUMO

El cáncer es una enfermedad genética producto de alteraciones en la secuencia o expresión del ADN. Estas alteraciones, según su origen, nos permiten clasificar el cáncer como esporádico y hereditario o familiar. En base a los registros de cáncer, en el Perú se espera que del 5 al 30% de todos los pacientes con cáncer, que equivale aproximadamente entre 2000 a 12 000 personas, presentarían cáncer del tipo familiar o hereditario, lo que representaría un similar número de familias con un riesgo mayor de desarrollar cáncer que el de la población en general. El propósito de la asesoría genética es identificar cánceres hereditarios en una familia con el fin de prevenir la enfermedad y la muerte por este mal. Es una estrategia que nos puede permitir detectar y diagnosticar con antelación estos cánceres. Es por este motivo que en el Instituto Nacional de Enfermedades Neoplásicas del Perú se realizan consultas de diagnóstico y asesoría genética desde hace cinco años, constituyéndose en un elemento importante para la lucha contra el cáncer, sin embargo, para lograr un mayor impacto en la salud requiere ampliar y fortalecer el proceso de capacitación en genética y asesoría genética a profesionales de la salud, sobre todo a médicos y enfermeras.

Cancer is a genetic disease caused by changes in the DNA sequence or expression. Based on the origin of these changes, cancer can be classified as sporadic, and hereditary or familial. Based on the cancer records in Peru, it is expected that 5 to 30% of all patients with cancer, i.e. about 2,000 to 12,000 people, have hereditary cancer, meaning that a similar number of families have a higher risk of developing cancer compared to the general population. Therefore, the purpose of genetic counseling is to identify hereditary cancers running in the family in order to prevent diseases and deaths caused by this condition. It is a strategy that allows us to detect and diagnose these types of cancer very early. For this reason, the National Institute of Neoplastic Diseases of Peru has been providing genetic diagnosis and counseling services for five years, and represents an important element in the fight against cancer. However, in order to have a greater impact on health, it is necessary to expand and strengthen the training process in genetics and genetic counseling to health care professionals, particularly to physicians and nurses.
