Trial Outcomes & Findings for Study of Cryoablation for Metastatic Lung Tumors (NCT NCT01957787)

NCT ID: NCT01957787

Last Updated: 2021-07-19

Results Overview

Local tumor control defined as the absence of local treatment failure 12 months following study cryoablation based on site-reported data. Local control was achieved if the 3-axis measurement (that is, the greatest trans-axial diameter plus the 2 perpendicular diameters) of a tumor at Month 12 was less than 20% larger than the 3-axis measurement of the tumor at Month 1 following study cryoablation. A separate evaluation of local tumor control at Month 12 following cryoablation was completed per index tumor. Month 1 data served as the baseline for this analysis; if Month 1 data was missing, Month 3 data were used. Tumors with a local failure at the prior study visit and those with repeat cryoablation procedures prior to Month 12 were counted as failures. Imaging for assessment of tumor measurements was performed using CT or 18 F-fluorodeoxyglucose positron emission tomography-CT with or without contrast.

Cryoablation
Participants underwent a cryoablation procedure with the Galil Medical Cryoablation System according to the manufacturer's guidelines. Participant preparation, anesthesia, intra-operative monitoring, and postoperative management for the study cryoablation procedure were identical to those for standard cryoablation treatment routinely performed at the clinical centers that participated in this study and were at the discretion of the Investigators. Tumors in both lungs were to be treated at an appropriate interval, determined on an individual basis. Treatment of bilateral index tumors in a single treatment session was not performed. All participants received cryoablation of up to 6 metastatic lung tumors. Treatment of all study index tumors was completed within an 8-week window.

PRIMARY outcome

Timeframe: Month 1 (Month 3 if Month 1 Data was missing) and Month 12

Population: Participants for whom cryoablation via Galil Medical Cryoablation System was attempted or performed and met all study entry criteria (mITT population). Multiple imputation methods for missing data were applied.

Local tumor control defined as the absence of local treatment failure 12 months following study cryoablation based on site-reported data. Local control was achieved if the 3-axis measurement (that is, the greatest trans-axial diameter plus the 2 perpendicular diameters) of a tumor at Month 12 was less than 20% larger than the 3-axis measurement of the tumor at Month 1 following study cryoablation. A separate evaluation of local tumor control at Month 12 following cryoablation was completed per index tumor. Month 1 data served as the baseline for this analysis; if Month 1 data was missing, Month 3 data were used. Tumors with a local failure at the prior study visit and those with repeat cryoablation procedures prior to Month 12 were counted as failures.

A technically successful treatment was defined by the presence of an ablation zone, ground glass opacity, or frank consolidation encompassing the targeted index tumor(s) at no later than the 1 month follow up visit after the cryoablation procedure. Technical success rates and 95% confidence intervals (CIs) were calculated using random effects logistic regression on a tumor level.

Population: Participants for whom cryoablation via Galil Medical Cryoablation System was attempted or performed and met all study entry criteria (mITT population) and evaluable KPS scores.

The KPS scale is a standard way of measuring the ability of cancer participants to perform ordinary tasks. KPS may be used to determine a participant's prognosis and to measure changes in a participant's ability to function. Assessments were made by examining the change in the baseline scores to those reported post-operatively. KPS scores range from 0 to 100. A higher score means the participant is better able to carry out daily activities.

Population: Participants for whom cryoablation via Galil Medical Cryoablation System was attempted or performed and met all study entry criteria (mITT population) and evaluable SF-12 scores.

The SF-12 is a shortened version of the well-known SF-36. The SF-12 assesses 8 domains (physical functioning, role limitations due to physical health problems, bodily pain, social functioning, general mental health, role limitations due to emotional problems, vitality, general health perception). The shorter instrument provides a general measurement of quality of life. Assessments were made by examining the change in the baseline scores to those reported post-operatively. The scores range from 0 to 100. A higher value indicates a better quality of life of the participant.

Measure
Cryoablation
n=130 participants at risk
Participants underwent a cryoablation procedure with the Galil Medical Cryoablation System according to the manufacturer's guidelines. Participant preparation, anesthesia, intra-operative monitoring, and postoperative management for the study cryoablation procedure were identical to those for standard cryoablation treatment routinely performed at the clinical centers that participated in this study and were at the discretion of the Investigators. Tumors in both lungs were to be treated at an appropriate interval, determined on an individual basis. Treatment of bilateral index tumors in a single treatment session was not performed. All participants received cryoablation of up to 6 metastatic lung tumors. Treatment of all study index tumors was completed within an 8-week window.
