Table 2.- DIAGNOSTIC VALUE OF 37.090 BREAST FINE NEEDLE ASPIRATION BIOPSY
CYTODIAGNOSTIC 1989-2004 ( Bayes )
1 as
malignant are calculated consecutively operated patients, with recorded
histopathological diagnosis of malignancy
2 as
benign are calculated cosecutively operated patients with benign
histopathological diagnoses (4.008) and all cytological negative patients,
not developing clinical signs of malignancy, in the 1 – 16 years period of
follow-up.
* Total number of breast aspiration
biopsies is shown in row 7 of I stratum of cytology – topography. From
5.906 positive cytological findings
2.639 are not calculated in this Bayes table because they have not
recorded consecutive histopathological finding needed
for gold standard.
** The number of positive cytological
findings with recorded consecutive histopathological findings is 3.267. 2.639 positive cytologic
findings are not calculated because they have not recorded consecutive
histopathological findings. (5.906 - 3.267 = 2.639).
