Adrenocortical carcinoma: prognostic indices based on clinical and immunohistochemical markers.
Adrenocortical carcinoma is a rare condition with an unpredictable prognosis as a rule. The authors retrospectively analyzed the clinical outcome of 46 patients (31 F, 15 M) during 16 years building up a numerical index for the prognosis, based on clinical and immunohistochemical data. Four indices were analyzed: J1= (Y + 2L + 4H)/T; J2 = (J1) square root of W/200; J3 = (O + Y + 2L + 4H)/T; J4 = (J3) square root W/200. Y = 1 when chronological age (CA) >33 mo, Y = 0 when CA < or =33 mo; L = 1 for right sided tumor and L = 0 for left sided tumor; H = 1 in presence of hypertension and H = 0 for normal blood pressure; T = length of disease in months; W = weight of tumor (g); O = 1 in the absence of p53 protein and O = 0 in the presence of p53. The chance of bad prognosis was observed when age is >33 mo, tumor is on the right side, systemic hypertension is present, tumor weight >250 g, in the absence of p53, J1, J2, J3 >0.4 (p <0.001) and J4 >0.5 (p <0.01). Clinical data and the mathematical model enabled us to establish probabilities of good prognosis in 78-96% and bad prognosis in 63-83%.
