ABSTRACT
Purpose To investigate the expression pattern and c1inicopatho1ogica1 significance of D2-40 in craniopharyngioma( CP). Methods Immunohistochemica1 method was used to assess D2-40 expression in 126 cases of craniopharyngioma. Statistic software was used to ana1yze the corre1ation between D2-40 expression and c1inicopatho1ogica1 features. Results The overa11 positive rate of D2-40 expression in 126 craniopharyngioma was 87. 30%. The rate of +, and were 44. 44%( 56/126 ),37. 30%( 47/126 )and 5. 56%(7/126)respective1y. In adamantinomatous CPs,D2-40 expression was observed in epithe1ia1 components corresponding to the stratum intermedium,whi1e in papi11ary CPs,it was immuno-positive in basa1 ce11s. With the increasing of the existence of inf1amma-tion in tumor,D2-40 expression was up-regu1ated. Tumor ce11s were over-expressed for D2-40 in basa1 ce11s and stratum intermedium ce11s of the invasive frontier. D2-40 expression was higher in the invasive craniopharyngioma than in the non-invasive craniopharyngio-ma. In addition,D2-40 expression was higher in the recurrent craniopharyngioma than in the non-recurrent craniopharyngioma. There were no significant re1ationship between D2-40 expression and gender,and histo1ogica1 c1assification of tumors. Conclusions D2-40 expression is associated with the deve1opment of craniopharyngioma,which can 1ead to enhance the tumor ce11 invasion,and may be re-1ated to inf1ammation-re1ated mechanisms. D2-40 expression may be one of the recurrence factors in patients with craniopharyngioma.
