Purpose: Conventional pathologic classifications of human renal cell carcinoma give
little insight into oncogenesis and little assistance in predicting the clinical behavior of
this disease. For genetic classification, deletion of the short arm of chromosome 3(3p),
the hallmark of nonpapillary/clear cell RCC, is a major diagnostic criterion. Because of
the limited routine applicability of cytogenetics and molecular genetic techniques we
investigated fluorescence In situ hybridization(FISH) for the detection of this aberration
in RCC.
Materials and Methods: Isolated nuclei from 8 human RCC paraffin embedded tissue
sections were examined with a dual colors FISH technique for loss of chromosome 3p.
Telomeric DNA probe from 3p and an internal ploidy control probe, centromeric probe of
chromosome 2, were applied to the isolated nuclei of RCC.
Results: 87.5% of the patients(7) lost chromosome Sp. The loss of 3p in the samples
tested was unrelated to patient age, gender, tumor stage, and grade.
Conclusions: FISH for the detection of loss in 3p from paraffin embedded tissue
sections provides a sensitive and feasible methods for the genetic classification of kidney
tumors and FISH is a very useful diagnostic tool for detection of the genetic aberrations
of the tumors.
