Abstract:
OBJECTIVESTo determine changes of insulin-like growth factor-1 (IGF-1) and IGF binding protein-3 (IGFBP-3) in serum samples from benign prostatic hyperplasia (BPH) patients and to evaluate the value of these molecules as possible etiologic factors for BPH.
METHODSThe serum IGF-1 and IGFBP-3 levels were measured with immunoradiometric assay(IRMA) in 64 cases of BPH and in 30 healthy subjects as controls. The cases of BPH were divided into 3 groups according to the prostate volume(PV). There were 18 cases(PV < or = 30 ml) in group A, 24 cases(PV31 approximately 50 ml) in group B, 22 cases(PV > or = 50 ml) in group C.
RESULTSThere were no statistical differences between the levels of Both IGF-1 and IGFBP-3 in BPH groups and healthy groups (both P > 0.05), but there were statistical differences among three groups of BPH. Both IGF-1 and IGFBP-3 levels in group C of BPH were significantly higher than those in group A (both P < 0.05). A positive correlation between the serum levels of IGF-1 and PV displayed(r = 0.58), as well as IGFBP-3 (r = 0.48).
CONCLUSIONSTogether these observations implicate IGF-1 and IGFBP-3 as important factors during the progression of BPH. It shows the value of non-operation treatment for this disease.
