Disease-specific Survival Rates Primary · Month 60

Disease-specific survival rate is the time in days from cryoprocedure to death due to kidney cancer. Subjects who are alive will be censored at date of their last visit. Subjects who have died from causes other than kidney cancer will be censored at the time of death. Patients are followed up for duration of registry which is 5 years.

Quality of Life Assessment Primary · Months 6 and 12

QoL SF12 is a health status survey to monitor outcomes in general and specific populations. Scoring system for the SF12 is norm-based scoring (NBS). This rescaling is done by linear transformation.The scale for each component is provided where the min = worst health and max= best health. Scale range (min-max,range): GH 23.9-63.7,39.8; PF 25.6-57.1,31.5 ; RP 23.6-57.5, 33.9; BP 21.7-57.7,36.1; VT 29.4-68.7, 39.4; SF 21.3-56.9,35.6; RE 14.7-56.3,41.6; HM 18.3-64.2,45.9; PCS 9.9-76,66 MCS 3.2-77.9,74.7

Sponsor's own description

TRACE is an observational, open-label, single-arm, multi-center registry of subjects who have undergone renal lesion cryoablation per their physician's standard of care. Patients 18 years of age or older who have been determined to be an appropriate candidate for cryoablation will be offered enrollment into the registry. Subjects will be observed for five years from the date of their cryoablation procedure.
