CIRSE Emprint Microwave Ablation Registry

Study Overview
=================
Brief Summary
-----------------
Observation of the clinical use of the Emprint Microwave Ablation System for the ablation of Liver Metastases of Colorectal Adenocarcinoma.

Detailed Description
-----------------
The CIRSE Emprint Microwave Ablation Registry (CIEMAR) aims to collect real-life data on the microwave ablation (MWA) of colorectal liver metastatic disease using the Emprint Microwave Ablation System. CIEMAR is a prospective, single-arm, multi-centre observational (non-interventional) study with the objective to observe the real-life use of MWA in Europe. The study will observe the use of the Emprint Microwave Ablation System and all patients included in CIEMAR will receive treatment with this device as their standard care for CRLM. Primary endpoint: local tumour control in liver at 12 months after the microwave ablation treatment on a per lesion basis Secondary objectives: Overall survival; Overall disease-free survival; Hepatic disease-free survival; Time to untreatable progression by thermal ablation; Systemic cancer therapy vacation; Quality of life; Adverse events and toxicity; Economic aspects In order to measure changes in the quality of life of enrolled patients at different moments in time before and after treatment with MWA, CIEMAR will incorporate the EORTC QLQ-C30 questionnaire. Filling out the quality-of-life questionnaire is entirely voluntary for the patient. The patient will be offered to fill out the questionnaire in his/her mother tongue. The registry is currently in design and it is planned to start patient inclusion in January 2020. The target is to enrol 1000 patients and patient enrolment will stop two years after the enrolment of the first patient. A follow-up period of three years has been defined by the CIEMAR Steering Committee.

What is the study measuring?

Primary Outcome Measures

| Outcome Measure | Measure Description | Time Frame |
| --- | --- | --- |
| Local Tumor Control | Local Tumor Control at 12 months on a per lesion basis | 12 months | 

Secondary Outcome Measures

| Outcome Measure | Measure Description | Time Frame |
| --- | --- | --- |
| Number of participants with acute and/or chronic adverse events according to the latest version of CTCAE | Safety and Tolerability will be monitored before, during and after the microwave ablation treatment. | 3 years | 
| Overall survival | Time from observation until death due to any cause (or censoring) | 3 years | 
| Overall disease-free-survival | Time from observation until disease progression or death assessed by the investigators | 3 years | 
| Hepatic disease-free-survival | Time from observation until disease progression in the liver or death assessed by the investigators. | 3 years | 
| Time to untreatable progression by thermal ablation | Time from the treatment to the point when liver malignancies can no longer be treated by thermal ablation. | 3 years | 
| Systemic cancer therapy vacation | Time that participants can be removed from systemic cancer therapies following the microwave ablation treatment. | 3 years | 
| Treatment specific quality of life | Treatment specific quality of life will be assessed using the EORTC-QLQ-C30 questionnaire which includes 28 questions on a scale of 1 to 4 where 1 indicates lower impact of the disease on the patient's quality of life and 4 represents a high impact. Additionally 2 questions using a scale form 1 to 7 are used to generally assess the patient's quality of life where 1 represents poor quality of life and 7 represents an excellent quality of life. | 1 year |
