Table 2

Clinical course and outcome of the patients.

Patient number	Disease-free duration (months)	Year of reoccurrence	Management for reoccurrence	Oncological outcome	Nephrological outcome
Case1	33	1992	nephrectomy	Disease-free for longer than 10 years	Dialysis dependent
Case2	41	1995	Conservative observation	Lost 29 months after reoccurence	Dialysis-free
Case3	56	2005	Conservative observation	Alive with disease for 22 months	Dialysis-free
Case4	16	2006	RFA	Alive with metastasis for 20 months	Dialysis-free
Case5	88	2007	RFA	Disease-free for 12 months	Dialysis-free
