Screening with Anal Cytology in Colombia: Initial Experience and Need for High-Resolution Anoscopy.

BACKGROUND: Men who have sex with men (MSM) living with human immunodeficiency virus (HIV) are at increased risk of anal cancer. Anal cytology can be used to screen for dysplasia, with high-resolution anoscopy (HRA) required for diagnostic confirmation. We describe the impact lack of HRA had on management of abnormal screening results in Bogotá, Colombia. MATERIAL AND METHODS: This retrospective cohort study includes MSM with HIV who underwent anal cytology screening between January 2019February 2020, with colorectal surgery (CRS) follow-up through July 2020. Cytology results included atypical squamous cells of undetermined significance (ASC-US), low-grade squamous intraepithelial lesion (LSIL), and high-grade squamous intraepithelial lesion (HSIL). Categorical and continuous variables were compared via Fisher's exact test and Wilcoxon rank-sum, respectively. RESULTS: Of 211 MSM screened, 68 had abnormal cytology: ASC-US (n = 23), LSIL (n = 41), HSIL (n = 4). Sixty (88.2%) were referred to CRS, and 51 (75.0%) attended ≥ 1 appointment. At initial assessment, 17 were referred for anal exam under anesthesia (EUA) for tissue resection, and 21 for rectosigmoidoscopy. Having perianal condyloma was associated with recommendation for EUA (P < 0.001), while cytology grade of dysplasia was not (P = 0.308). Eleven (16.2%) underwent EUA for condyloma resection. CONCLUSIONS: Few studies have described anal cancer screening in settings without HRA. We found lack of HRA limited management of abnormal cytology in Colombia. Those with condyloma underwent resection, but HRA remains necessary to localize and treat microscopic disease. Next steps include implementation of HRA in order to further develop the anal cancer screening program for MSM with HIV in Bogotá.

Cáncer colorrectal durante la pandemia COVID-19, recomendaciones de la Asociación Colombiana de Coloproctología / Recommendations of the Colombian Association of Coloproctology for Management of Colorectal Cancer during the COVID-19 Pandemic

Resumen La pandemia por el coronavirus 2 del síndrome respiratorio agudo severo (SARS-CoV-2), (coronavirus disease-19 [COVID-19]), ha alterado por completo toda la realidad mundial con repercusiones económicas, sociales y grandes compromisos de los sistemas de salud. La enfermedad ha afectado a todos los países en los 5 continentes; y en nuestro país, desde el primer caso, se han venido tomando medidas para prepararnos mejor ante esta crisis. Pese a que se trata de un virus respiratorio, se ha documentado su presencia en diferentes tejidos y órganos de los seres humanos. Aunque la presentación clínica en su mayoría tiene síntomas leves, se sabe que un porcentaje importante tiene manifestaciones graves que pueden llevar a complicaciones graves y la muerte. El cáncer colorrectal es un tumor prevalente en nuestra población y obliga a tener una mejor preparación para tratarlo durante este período. Desde la Asociación Colombiana de Coloproctología, basados en los diferentes reportes de la literatura, en las recomendaciones de las diferentes asociaciones internacionales y en nuestra propia experiencia, se realiza una revisión del cáncer colorrectal durante la pandemia de COVID-19 y se comparten algunas recomendaciones para el manejo de los pacientes con esta patología revisando las diferentes opciones de manejo según la presentación de la enfermedad.

Abstract The economic and social repercussions and the enormous commitment required of health care systems by the severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) pandemic (coronavirus disease [COVID-19]) has completely altered world reality. The disease has affected all countries on all five continents. In Colombia, from diagnosis of the very first case, measures have been taken to better prepare ourselves for this crisis. Although it is a respiratory virus, its presence in various human tissues and organs has been documented. Despite the fact that its clinical presentation is most often in the form of mild symptoms, a significant percentage of those infected have severe manifestations that can lead to serious complications and death. Colorectal cancer is a prevalent tumor in our population, and this pandemic forces to prepare ourselves better to treat it during this period. The Colombian Coloproctology Association has reviewed reports in the literature and recommendations of various international associations and on our own experience with colorectal cancer during the COVID-19 pandemic. We present our recommendations for management of patients with this pathology and review management options according to disease presentation.
