Back ground and aim: It is well known that the kidney of von Hippel-Lindaus (VHL) disease and after persistent hemodialysis contains various precursor and precancerous lesions of renal cell carcinoma (RCC). Here, we aimed to investigate the genetic abnormalities in such lesions using laser capture microdissection (LCM) and chromogenic in situ hybridization (CISH). Materials and methods: On the kidney tissue derived from 2 cases of VHL disease and 7 cases of persistent hemodialysis, LCM was performed to cut out atypical tubules and cysts for RT-PCR followed by cDNA microarray, and CISH for evaluate the cchromosome numbers of #3, 7, 17 and Y, which have been known to be related with pathogenesis of RCCs. Results and discussion: The extracted RNAs were not appropriate for RT-PCR or cDNA microarray in the quality. CISH also failed to reveal the signals. Along with these attempts, we performed LCM study using frozen ovarian cancer tissue to evaluate the expression of the prolactin receptor and to demonstrate the copy numbers of Her2 gene in extramammary Paget disease, both of which were successful (Asai-Sato, Nagashima et al., in press; Ogawa, Nagashima, et al., submitted). Based on these facts, the methods to collect the RCC samples should be reconsidered for future study.
