Purpose : The purpose of this study was to investigate whether the expressions of
alpha-1-antichymotrypsin(ACT) and/or p53 protein in advanced prostate cancer were
related with bony metastases.
Materials and Methods : The immunohistochemical study with ACT and p53 included
7 archival transurethral resection and 14 prostate biopsy specimens from patients with
prostate cancer who showed high serum PSA level(>10ng/§¢) and periprostatic or lymph
node involvement on imaging study. Whole body bone scan was perfomed to detect
bony metastatis in all patients.
Results : Four out of 5 cases showing strong expression patterns with ACT protein
showed abnormal hot uptakes on whole body bone scan. ACT proteins were weakly
expressed in seven out of eight cases without bony metastases. p53 protein was
expressed in 13 cases, but there was no statistically significant relation between the
expression of p53 protein and bony metastasis. Either, there was no significant relation
between ACT and p53 protein expression patterns.
Conclusions : Our results suggested that the strong expression of ACT protein
combined with high serum PSA level(>10ng/§¢) and whole body bone scan could be the
useful method for confirming bony metastasis although not adequate for screening test.
The expression of p53 protein appears to be associated with progression of prostate
cancer, but there was no statistically significant relation with bony metastasis.
