Abstract

Eight patients with surgically treated glioblastoma who were eligible for radiotherapy and nine patients with brain metastases from lung and breast cancer underwent CT before and after injection of contrast medium CBV and PS were calculated in the contrastenhancing lesion area in the area of perilesional oedema and in the normalappearing white matter NAWM normalised to contralateral symmetrical areasNo significant differences were found for normalised CBV nCBV and nPS in NAWM regions between metastasis and glioma Significant differences in nPS p0005 were found between the typically vasogenic oedema surrounding the metastases and signal alteration surrounding the glial neoplasm On the contrary no significant differences were detected in the same areas for nCBVPCT can analyse the histopathological substrate underlying the hypodense peritumoural halo and differentiate between vasogenic oedema and neoplastic infiltration on the basis of the PS parameter In our study PS was more informative than CBV These findings can be used to integrate plans for radiation therapy and/or surgeryScopo del presente studio è stato identificare l’infiltrazione tumorale del tessuto cerebrale circostante l’area lesionale d’impregnazione in pazienti con glioblastoma tramite tomografia computerizzata perfusionale TCP valutando i parametri volume ematico cerebrale CBV e superficie di permeabilità PSOtto pazienti affetti da glioblastoma trattato chirurgicamente candidati alla radioterapia e nove pazienti con metastasi cerebrali da tumore polmonare e mammario hanno effettuato una TC prima e dopo somministrazione di mezzo di contrasto Il CBV ed il PS sono stati calcolati nell’area lesionale di impregnazione nell’area di edema perilesionale e nella sostanza bianca apparentemente sana NAWM normalizzati n con aree simmetriche controlateraliNon sono emerse differenze statisticamente significative per nPS ed nCBV nelle sostanza bianca apparentemente sana tra metastasi e glioma Differenze statisticamente significative per nPS p0005 sono emerse tra l’edema perimetastatico puramente vasogenico e l’alterazione di segnale circostante le lesioni gliali Al contrario nessuna differenza è stata trovata nelle stesse aree per il nCBVLa TCP è in grado di valutare il substrato istopatologico nell’alone ipodenso peritumorale e differenziare tra edema vasogenico ed infiltrazione tumorale attraverso il parametro PS Nel nostro studio il PS è risultato più informativo del CBV Queste informazioni possono essere utilizzate per integrare il piano di trattamento radioterapico e/o chirurgico
