PRIMARY OBJECTIVE:
I. Estimate the 2-year local recurrence rate for microwave ablation within a basket.
SECONDARY OBJECTIVES:
I. Evaluate whether microwave ablation offers treatment benefit for safety when compared to wedge resection using a contemporaneous database consisting of a commensurate surgical patient population.
II. Evaluate whether microwave ablation offers treatment benefit for efficacy when compared to wedge resection using a contemporaneous database consisting of a commensurate surgical patient population.
III. Evaluate whether microwave ablation offers treatment benefit for changes in patient reported outcomes when compared to wedge resection using a contemporaneous database consisting of a commensurate surgical patient population.
OUTLINE:
Patients undergo standard care microwave ablation or wedge resection followed by contrast-enhanced computed tomography (CT) imaging at 1, 6, 12, 18 and 24 months. Patients also complete questionnaires over 10-15 minutes at baseline up to 9 months.
