ABSTRACT

AIM: To evaluate the precision of the pre-surgical measurement of the size of breast cancer by contrast-enhanced spectral mammography (CESM). MATERIAL AND METHODS: This was a retrospective study of 204 breast cancers. Variables related to tumour biology and anthropometric variables were recorded and considered when evaluating the efficacy of CESM in predicting tumour size. Microscopic measurement of the largest diameter of the tumour at pathology was chosen as the reference standard. RESULTS: The mean size of tumours at pathology was 20.7±15.8 mm, while at CESM it was 23.6±16.7 mm (Bland-Altman 2.9 mm overestimation, 2.9 mm; 95% confidence interval [CI]: -10.3-16.2 mm). Spearman's correlation coefficient was 0.83 (p<0.0001). The concordance analysis indicated that 37.8% of the measurements were concordant, 47% were overestimated, and 15.2% were underestimated. Tumour size, nodal involvement, breast density, and breast size significantly modified the sizing accuracy. CONCLUSION: Quality of tumour size prediction with CESM is good, and this appears to be a promising imaging technique in the surgical planning of breast cancer. Biological tumour features, and anthropological characteristics of the patients do, however, affect the diagnostic precision and should be taken into account.

ABSTRACT

Es bien conocido que el grado de vascularización de las lesiones mamarias se relaciona con su malignidad. Por ello, las técnicas de diagnóstico por imagen que estudian funcionalmente las lesiones han cobrado mucha relevancia en los últimos años. La mamografía con medio de contraste y energía dual es una técnica de reciente aparición, aparentemente prometedora en el cáncer de mama, que informa del grado de vascularización de la lesión junto con la información morfológica habitual. El propósito de este artículo es presentar el estado actual de esta nueva técnica de imagen. Basándonos en una experiencia de 15 meses, ilustramos esta revisión con casos clínicos que nos permiten presentar también sus ventajas y limitaciones (AU)


The degree of vascularization in breast lesions is related to their malignancy. For this reason, functional diagnostic imaging techniques have become important in recent years. Dual-energy contrast-enhanced mammography is a new, apparently promising technique in breast cancer that provides information about the degree of vascularization of the lesion in addition to the morphological information provided by conventional mammography. This article describes the state of the art for dual-energy contrast-enhanced mammography. Based on 15 months’ clinical experience, we illustrate this review with clinical cases that allow us to discuss the advantages and limitations of this technique (AU)

ABSTRACT

Propósito: La incidencia y mortalidad por cáncer de mama en Gran Canaria es una de las más altas de España. En este estudio analizamos las características epidemiológicas y clínico-patológicas de un grupo de pacientes con diagnóstico de cáncer de mama. Material y métodos: Se estudiaron 474 pacientes con cáncer de mama, diagnosticadas y tratadas entre diciembre de 1990 y marzo de 1996, en los dos Hospitales Generales de nuestra Provincia. Se confeccionó una base de datos y los análisis estadísticos realizados fueron, fundamentalmente, medidas de tendencia central y medidas de dispersión. Resultados: La edad media y mediana fue de 60 años. El grupo entre 56 y 60 años representó el 17,7 por ciento. El 83,8 por ciento de las neoplasias se detectaron por autopalpación y el 9,3 por ciento por mamografía. El 8,9 por ciento tenían antecedentes familiares de carcinoma de mama en primer grado. Se practicó mastectomía radical modificada en el 78,1 por ciento y cirugía conservadora en el 19,4 por ciento de los casos. Conclusiones: En nuestra serie, un alto porcentaje de tumores 83,8 por ciento fueron palpables precisando en el 78,1 por ciento la realización de mastectomía radical modificada (AU)
