| Research Abstract |
The clonality of sporadic multiple renal cell carcinomas are unknown. We compared the genetic background of the multiple tumors by the mutation analyses of von Hippel Lindau (VHL) tumor suppressor gene. Furthermore, comparative genomic hybridization (CGH) was used to investigate genetic differences. The main tumor and the satellite tumor of four patients with renal cell carcinomas were investigated. In patient #1, no mutation of VHL gene was detected in the main tumor, however, missense mutation was detected in codon 167 (CGC→CCG; Arginme→Proline) in the satellite tumor. In patient #2, no mutation of VHL gene was detected in the main tumor, however, nonsense mutation was detected in codon 185 (TAC→TAG; Tyrosine→stop codon) in the satellite tumor. In patient #3, one base deletion was detected in codon 133 in the main tumor, however, no mutation of VHL gene was detected in the satellite tumor. In patient #4, no mutation of VHL gene was detected both in the main tumor and the satellite tumor, In summary, no common mutation in both the main and the satellite tumor was detected, which suggests clonality of multiple renal cell carcinomas are different. The result of the CGH supports the idea because common abnormality is rare between the main tumors and the satellite tumors.
