Larinks kanserlerinde bilgisayarlı tomografik ve histopatolojik tümör (T) evrelemenin karşılaştırılması

maç: Larenks kanserlerinde bilgisayarlı tomografi (BT) bulgularının ameliyat sonrası histopatolojik sonuçlarla karşılaştırılması. Gereç ve yöntem: Biopsi ile larenks kanseri tanısı almış yaş ortalaması 54,5 olan, 49'u erkek 52 hasta ameliyat öncesi BT tetkiki ile tümör lokalizasyonu (T) ve derin invazyon (preepiglottik ve paraglottik boşluk, subglottik alan ve kıkırdaklar) yönünden değerlendirildi. Sonuçlar patolojik (p) bakı sonuçları ile karşılaştırıldı. Bulgular: Doğruluk oranı glottik yerleşimli olanlarda %80, supraglottik yerleşimli olanlarda %64, transglottik olanlarda %76 olup, genel doğruluk oranı %73 olarak bulundu. Sonuç: T3 ve T4 evredeki tümörlerde BT evre doğruluk oranı, Tl ve T2 evre tümörlere göre yüksek bulundu. Bu doğruluk oranları literatürdekine paraleldir. Klinik muayeneyle birlikte BT değerlendirilmesi histopatolojik evrelemenin doğruluğunu arttırmaktadır.

Comparison of computerized tomographic and histopathological tumor (T) staging of laryngeal cancers

Objective: We compare the findings of computerized tomographic (CT) imaging with histopathologic results in larengeal cancer. Patients and method: Fifty-two patients (49 males, mean age 54,5) were evaluated preoperatively by CT with regard to localization (T) and deep involvement (preepiglottic space, laryngeal cartilages, paraglottic and subglottic areas). The results were correlated with histopathologic (p) findings. Results: The accuracy of CT were 80% for glottic; 64% for supraglottic, 76% for transglottic region tumors. Overall accuracy was 73%. Conclusion: Histopathologic and CT staging results are highly correlated in T3 and T4 stage tumors than Tl and T2 stage tumors, similar to those in the literature. The ccuracy of histopathologic staging enhances by concomitant use of clinical and radiologic findings.
