What this trial studies

This study investigates the safety and effectiveness of MRI-guided focused ultrasound combined with microbubble therapy and radiotherapy for patients with malignant melanoma and non-melanoma skin cancer. The approach utilizes low-power ultrasound to stimulate microbubbles in the tumor before administering radiation, aiming to enhance the therapeutic effect. The primary goal is to assess the safety profile of this combined treatment, while the secondary goal focuses on evaluating the tumor response through radiological measurements.

Who should consider this trial

Good fit: Ideal candidates include adults aged 18 and older with biopsy-confirmed malignant melanoma or non-melanoma skin cancer, including metastatic lesions.

Not a fit: Patients who are pregnant or lactating, or those with certain health conditions that prevent participation, may not benefit from this study.

Why it matters

Potential benefit: If successful, this treatment could improve the efficacy of radiotherapy for patients with skin cancer.

How similar studies have performed: Other studies have shown promise with similar ultrasound and microbubble approaches, suggesting potential for success in this novel application.
