Open Versus Laparoscopic Ablation of Liver Malignancies (OPTIMAL)
March 11, 2024 updated by: Hans-Christian Pommergaard, Rigshospitalet, Denmark
Laparoscopic Versus Open Ablation of Liver Malignancies: a Randomized, Controlled Multicenter Trial
The purpose of this study is to compare laparoscopic ablation to open ablation of liver malignancies regarding complication rates and ablation response as well as quality of life following the surgery.

Intervention / Treatment
Detailed Description
Liver malignancies is a major cause of cancer-related mortality and the incidence is increasing.
Patients with liver malignancies are often left with limited surgical treatment options due to extensive tumor burden or comorbidities.
Ablation is a less invasive treatment for these patients that can be performed percutaneously, by laparoscopy or open surgery.
Ablation during open surgery has a high potential of complications.
Laparoscopic ablation presumably has a lower complication rate than during open surgery, yet still offers some of the same advantages needed for tumors in locations not favorable for percutaneous ablation.
This study aims to compare laparoscopic ablation with ablation during open surgery to investigate a treatment option with a supposed lower complication rate and equally treatment effectiveness after one month.

Arms and Interventions
Participant Group / Arm |
Intervention / Treatment |
---|---|
Active Comparator: Open ablation
Laparotomy performed for open ablation of the tumor
|
Heat-based ablation modality performed by laparotomy.
Centers may use either radiofrequency or microwave ablation.
The modality should be the same in both groups.
|
Experimental: Laparoscopic ablation
Ablation of the tumor performed by laparoscopic approach
|
Heat-based ablation modality performed by laparoscopy.
Centers may use either radiofrequency or microwave ablation.
The modality should be the same in both groups.

Primary Outcome Measures
Outcome Measure |
Measure Description |
Time Frame |
---|---|---|
Complications measured by the comprehensive complication index.
Time Frame: Complications are registered and clavien-dindo graded 30 days after surgery.
|
Comprehensive Complication Index (CCI) scores compared between open and laparoscopic ablation groups.
A higher CCI score represents a larger complication burden.
|
Complications are registered and clavien-dindo graded 30 days after surgery.
|
Secondary Outcome Measures
Outcome Measure |
Measure Description |
Time Frame |

Time Frame: 30 days after surgery.
|
Presence of tumor remnants in ablation cavity one month after procedure evaluated with contrast enhanced CT.
|
30 days after surgery.
|
Quality of Recovery score (QoR)
Time Frame: Before surgery and postoperative day 1, 7 and 30.
|
Questionnaires are filled out prior to surgery and after
|
Before surgery and postoperative day 1, 7 and 30.

Time Frame: Before surgery and on postoperative day 30.
|
Questionnaires are filled out prior to surgery and after
|
Before surgery and on postoperative day 30.
|
Overall survival
Time Frame: Up to 90 days after surgery
|
Overall and disease-free survival measured as survival status 90 days after surgery.
