Purpose : Renal cell carcinoma has been characterized by an abnormality on the short
arm of chromosome 3, which suggests the presence of a tumor suppressor gene at this
location. The aim of study was to investigate the role of tumor suppressor genes on the
short arm of chromosome 3 in the mechanism of tumorigenesis in sporadic renal cell
carcinoma.
Materials and Method : The DNA from normal and tumor tissue from 48cases with
renal cell carcinoma was analyzed for allele loss on chromosome 3p by polymerase chain
reaction using microsatellite marker.
Results : A total of 37 of 48 informative tumors(77%) showed loss of
heteroxygosity(LOH) at one or more loci. Detailed analysis of the pattern of LOH on the
chromosome 3p suggested that mutations of other genes in chromosome 3p13-p24, in
addition to VHL gens in chromosome 3p25, are required for malignant tumor growth.
There was the statistically significant correlation between the extent of LOH and
cancer cell type(clear vs. others)(p=value 0.048, Fisher's exact test). A total of 26 of 37
clear cell types(70%)revealed LOH on chromosome 3p, but all of 11 non clear cell types
including 2 granular cell types, 3 chromophobe types, 1 sarcomatoid cell type and 5
mixed cell types showed LOH.
There was no correlation between LOH and other clinico-pathological factors including
patients age, sex, symptom, tumor size, stage of disease and tumor cell grade.
Conclusions : Our data suggest that, in addition to VHL gene, at least one tumor
suppressor gene for the genesis of sporadic remal cell carcinoma exists on the short
arm of chromosome 3.
