Official title
Cryoablation as Alternative for Lumpectomy in Early-Stage Breast Cancer: The CRYSTAL Trial
Overview
The goal of this randomised controlled trial is to compare ipsilateral breast cancer recurrence rates in patients with early-stage breast cancer between patients treated with breast conserving surgery and patient treated with percutaneous cryo-ablation.
Interventions
- Procedure Percutaneous cryoablation
In this trial, the IceCure Prosense Cryoablation System will be used to execute the percutaneous cryoablation procedure. - Procedure Breast-conserving surgery
Breast-conserving surgery
Primary outcome measures
- Ipsilateral breast cancer recurrence [Time frame: Until 5 years after the intervention]
Secondary outcome measures (12)
- Complication Rate [Time frame: Within 30 days after the intervention]
- Regional breast cancer recurrences [Time frame: Until 5 years after the intervention]
- Disease Free Survival [Time frame: until 15 years after the intervention]
- Overall Survival [Time frame: through study completion, an average of 15 years]
- Cosmetic Outcomes [Time frame: at baseline, 6 months and 1 year after the intervention]
- Hospital-related costs [Time frame: Until 5 years after the intervention]
- Out-of-hospital (non)-medical costs [Time frame: Until 5 years after the intervention]
- Generic Health-related Quality of Life [Time frame: At baseline, 6 months after the intervention, 1 and 5 years after the intervention]
- Disease-specific quality of life [Time frame: At baseline, 6 months after the intervention, 1 and 5 years after the intervention]
- Complete ablation rate [Time frame: 2 weeks after the intervention (cryoablation)]
- Predictive value of MRI [Time frame: until 5 years after the intervention]
- Proportion of reinterventions [Time frame: For the duration of the study, most likely within 2 weeks after the intervention]
