Abstract(s)
A ecografia é o exame de primeira linha na
identificação e caraterização de tumores anexiais.
Foram descritos diversos métodos de diagnóstico
diferencial incluindo a avaliação subjetiva do
observador, índices descritivos simples e índices
matematicamente desenvolvidos como modelos
de regressão logística, continuando a avaliação
subjectiva por examinador diferenciado a ser o
melhor método de discriminação entre tumores
malignos e benignos. No entanto, devido à
subjectividade inerente a esta avaliação tornouse
necessário estabelecer uma nomenclatura
padronizada e uma classificação que facilitasse
a comunicação de resultados e respectivas
recomendações de vigilância.
O objetivo deste artigo é resumir e comparar
diferentes métodos de avaliação e classificação
de tumores anexiais, nomeadamente os modelos
do grupo International Ovary Tumor Analysis
(IOTA) e a classificação Gynecologic Imaging
Report and Data System (GI-RADS), em termos
de desempenho diagnóstico e utilidade na prática
clínica.
Ultrasonography is currently considered as the primary imaging modality for identifying and characterizing adnexal masses. Several approaches of differential diagnosis have been proposed, including examiner’s subjective impression, simple descriptive scoring systems and logistic regression models. After all, subjective impression of an experienced examiner is currently believed to be the best approach. However, due to the subjective nature of the examiner’s impression, there is a need for a standardized nomenclature and definitions for all tumour features evaluated and structured reporting to allow for improved communication of results and recommendations for follow-up. The aim of this article is to summarize and compare different methods of evaluation and classification of adnexal masses, namely the International Ovary Tumor Analysis (IOTA) models and the Gynecologic Imaging Report and Data System (GIRADS) classification, in terms of accuracy and utility in clinical practice.
