Resumo(s)
O presente trabalho representa o documento final de avaliação do Mestrado em Análises Clínicas da Faculdade de Farmácia da Universidade de Lisboa.
Este é composto por duas partes. A primeira parte consiste no Relatório do estágio efetuado no Laboratório Central da Synlab. onde se descreve o trabalho realizado, nomeadamente os parâmetros analisados, metodologias mais comuns e sistema de avaliação da qualidade interno para cada uma das valências incluídas.
A segunda parte corresponde à monografia, “Marcadores Bioquímicos para o Diagnóstico do Cancro do Pâncreas”. Sendo o cancro do pâncreas uma condição fatal de incidência crescente com índices de mortalidade muito elevados é crucial, para a diminuição da sua letalidade, a deteção precoce desta patologia. Isto passa, em grande parte, pela melhoria dos seus métodos de diagnóstico, entre os quais se inclui o uso de marcadores tumorais. Estes são substâncias cuja presença em níveis elevados pode indicar a presença de um tumor, sendo que um bom marcador deverá ter tanto uma alta sensibilidade como uma elevada especificidade para a doença que se quer diagnosticar.
Assim, o tema proposto visa fazer uma revisão dos vários tipos de marcadores bioquímicos que podem ser utilizados no diagnóstico desta patologia, nomeadamente os marcadores CA19-9, CA50, CA242, CEA, DUPAN-2, a família de genes RAS e micro- RNAs.incluindo a especificidade e sensibilidade de cada um deles e a eventual utilidade no diagnóstico diferencial de outras doenças, explorando, sempre que possível, os mecanismos que levam à alteração dos seus valores no cancro do pâncreas. Irá, também, ser abordado o uso e as vantagens de painéis de marcadores com o mesmo objetivo.
The present work represents the final evaluation document for the Master's degree in Clinical Analysis at the Faculty of Pharmacy, University of Lisbon. This is composed of two parts. The first part consists of the internship report carried out at Synlab’s Central Laboratory, which describes the work carried out, namely the parameters analyzed, the most common methodologies and the internal quality assessment system for each of the valences included. The second part corresponds to the monograph, "Biochemical Markers for the Diagnosis of Pancreatic Cancer". Since pancreatic cancer is a fatal condition with an increasing incidence and very high mortality rates, early detection of this pathology is crucial to reducing its lethality. This largely involves improving diagnostic methods, including the use of tumor markers. These are substances whose presence at high levels can indicate the presence of a tumor, and a good marker should have both high sensitivity and high specificity for the disease it is intended to diagnose. Therefore, the proposed topic aims to review the various types of biochemical markers that can be used in the diagnosis of this pathology, namely the markers CA19-9, CA50, CA242, CEA, DUPAN-2, the RAS gene family and micro-RNAs, including the specificity and sensitivity of each of them and their possible usefulness in the differential diagnosis of other diseases, exploring, whenever possible, the mechanisms that lead to changes in their values in pancreatic cancer. The use and advantages of panels of markers for the same purpose will also be discussed.
