To investigate possible histopathological differences between tumours with and without such losses, we compared loss of heterozygosity data from 51 tumours with 1 histological and 2 different cytological classifications of renal\u2010cell tumour. Using the cytological classification of Thoenes <jats:italic>et al.<\/jats:italic>, we only found tumours with loss of heterozygosity in these authors' clear\u2010cell category. Possibly, only these tumours arise by a mechanism of double loss of a tumour\u2010suppressor gene on 3p, non\u2010clear\u2010cell renal tumours having a different genetic background. Alternatively, deletions may occur in all subtypes, in which case those subtypes in which no LOH is found may also contain deletions too small to be detected with the set of 3p probes we used. A cytogenetic analysis was carried out on 30 of the tumours. Results of molecular and microscopic cytogenetic analyses did not seem to be in agreement in 12 cases. In 6 of these we found allelic losses in tumours showing morphologically normal copies of chromosome 3. Mitotic recombination or loss of one chromosome 3 homologue followed by duplication of the remaining homologue is a likely explanation. The other 6 cases showed microscopic abnormalities of chromosome 3 which were not reflected, or only partly reflected, as allelic losses. These discrepancies are caused either by the limitations of microscopic analysis in exactly determining a breakpoint or tracing a translocated part of a chromosome, or by the failure of molecular analysis to demonstrate LOH if this occurs in only a minority of cells.<\/jats:p>","DOI":"10.1002\/ijc.2910530302","type":"journal-article","created":{"date-parts":[[2007,2,19]],"date-time":"2007-02-19T23:26:49Z","timestamp":1171927609000},"page":"353-357","source":"Crossref","is-referenced-by-count":36,"title":["Loss of heterozygosity at the short arm of chromosome 3 in renal\u2010cell cancer correlates with the cytological tumour type"],"prefix":"10.1002","volume":"53","author":[{"given":"A.
