Guia de cáncer de pene de la Sociedad Colombiana de Urología / Colombian Society of Urology Penile Cancer Guideline

El cáncer de pene tiene una incidencia de 1.11 por 100.000 habitantes en Colombia, representado en el 95% por carcinoma de células escamosas el cual representa una alta morbilidad y mortalidad, La Sociedad Colombiana de Urología realizo la adaptación de la guía de cáncer de pene para el año 2021 con revisión de la literatura, esta guía permite realizar una evaluación y tratamiento del cáncer de pene, enmuchas ocasiones con el objetivo de preservación de órgano utilizando la ecografía como determinante para evaluar el compromiso de la lesión a las estructuras del pene, los estudios de extensión dependerán de hallazgos al examen físico como ganglios o compromiso local de la enfermedad, de acuerdo al tipo de lesión y su estadificación puede recibir terapia con agentes tópicos, radioterapia, cirugía láser, cirugía preservadora de órgano o penectomía total; La linfadenectomía inguinal permitirá mejorar la supervivencia en tumores de riesgo intermedio y alto (>pT1G2), posteriormente la quimioterapia adyuvante esta en el grupo de pacientes en el cual la intención sea curativa, aunque en terapia paliativa de segunda línea se encuentran los platinos y texanos como alternativa pero con pobre respuesta (<30%); los esquemas de seguimiento se realiza de acuerdo al estadio y el compromiso ganglionar. Al final se presentan los resultados de actividad sexual después de cirugía preservadora de órgano; Esta guía abarca la literatura actualizada del cáncer de pene, el cual es útil para el manejo por parte de los profesionales de salud del país.

Penile cancer has an incidence of 1.11 per 100,000 inhabitants in Colombia, 95% represented by squamous cell carcinoma which represents a high morbidity and mortality, The Colombian Society of Urology adapted the penile cancer guide to The year 2021 with a review of the literature, this guide allows an evaluation and treatment of penile cancer, in many cases with the objective of organ preservation, using ultrasound as a determinant to evaluate the commitment of the injury to the structures of the penis, Extension studies will depend on findings on physical examination such as lymph nodes or local involvement of the disease, according to the type of lesion and its staging, it can receive therapy with topical agents, radiotherapy, laser surgery, organ-sparing surgery or total penectomy; Inguinal lymphadenectomy will improve survival in intermediate and high risk tumors (> pT1G2), subsequently adjuvant chemotherapy is in the group of patients in which the intention is curative, although platinum and Texans are found in second-line palliative therapy as an alternative but with a poor response (<30%); the follow-up schemes are carried out according to the stage and lymph node involvement. At the end, the results of sexual activity after organ-sparing surgery are presented; This guide covers the updated literature on penile cancer, which is useful for the management of health professionals in the country.

Citologia esfoliativa convencional versus citologia em meio líquido para prevenção e diagnóstico precoce do carcinoma escamo celular (CEC) oral / Conventional cytology versus liquid-based cytology for prevention and early diagnosis of Oral Squamous Cell Carcinoma (OSCC)

Objetivando avaliar a concordância, sensibilidade e especificidade diagnóstica dos métodos citológicos:convencional e em meio líquido, foi realizado um estudo de caso-controle, no Ambulatório deCabeça e Pescoço do Hospital de Câncer de Pernambuco, sendo selecionados 182 indivíduos doentese 179 sãos, no período de setembro de 2002 a janeiro de 2004, os quais, permitiram através de assinatura de termo de consentimento livre e esclarecido a realização de exames (clínico/ citológicoesfoliativo - cytobrush) na área carcinomatosa e em área sã, constituindo, respectivamente, o grupo de casos e controles. Os dados obtidos foram analisados através dos softwares estatísticos SPSS(Statistical Package for Social Science) e Epi-Info versão 6.4. Os resultados evidenciaram que os métodosdiagnósticos citológicos apresentaram entre os casos: sensibilidade= 96,9% (IC= 95%: 92,5% a98,8%); especificidade= 75,0% (IC= 95%: 21,9% a 98,7%) e acurácia= 96,3% (IC=95%: 92,5% a 98,5%);e entre os controles: sensibilidade= 91,0% (IC=95%: 84,1% a 95,2%); especificidade = 57,5% (IC=95%:41,0% a 72,6%) e acurácia= 82,7% (IC=95%: 76,3% a 88,0%). A citologia convencional e em base--líquida apresentaram concordância com o diagnóstico histopatológico em mais de 90%. Conclui-se, portanto, que, se bem indicado e executado, o exame citológico pode ser utilizado rotineiramente como exame complementar, pois ambos apresentaram alta sensibilidade e razoável especificidade,cabendo à citologia convencional maior especificidade para o diagnóstico das lesões orais.

The purpose of this study was to evaluate the sensitivity, specificity, and concordance between conventionalcytology and liquid-based cytology. A case-control study was developed at the Head andNeck ambulatory service of Hospital do Cancer de Pernambuco. A hundred and eighty-two patientswith primary Oral Squamous Cellular Carcinoma (OSCC) (case group) and 179 individuals with normalbuccal mucosa (control group) were selected, from September 2002 to January 2004. They agreed tobe submitted to clinical examination and exfoliative cytology of the oral cavity, by signing a documentof consent. The data were analysed by Statistical Package for Social Science (SPSS) and Epi-Info 6.4 program.Among the cases, the cytologic methods demontrated a sensitivity= 96.9% (IC= 95%: 92.5% to98.8%), specificity= 75.0% (IC=95%: 21.9% to 98.7%), and accuracy= 96.3% (IC=95%: 92.5% to 98.5%).Among the controls the results were: sensitivity= 91.0% (IC=95%: 84.1% to 95.2%);, specificity= 57.5%(IC=95%: 41.0% to 72.6%), and accuracy= 82.7% (IC=95%: 76.3% to 88.0%). Conventional cytologyand liquid-based cytology demonstrated a diagnostic concordance with histopathology of more than90%. In conclusion if properly indicated and executed, they can be routinely used as complementarydiagnostic methods. When compared to each other, conventional cytology and liquid-based cytologyshowed a high sensitivity and reasonable specificity, conventional cytology having higher specificity.
