Magnetolith® (high-energy shockwave therapy) has emerged as a non-invasive therapeutic option for refractory pain management. This study evaluates its preliminary impact on a cohort of gynecological cancer patients with chronic post-treatment pain. Material/Methods: Seven patients with a history of cervical cancer treated with chemo-radiotherapy and/or brachytherapy were included. All patients were in strict complete clinical and radiological response at the time of Magnetolith® treatment. Each patient underwent between 1 and 10 sessions, with pulse ranges from 10,000 to 45,000 per session (levels 6-8; frequency of 8-10 Hz). Pain intensity was assessed using the Visual Analog Scale (VAS) before and after treatment. Toxicity and patient satisfaction were also recorded.

Results: •

Treatment details: The therapy was delivered on consecutive days, with each session lasting between 20 minutes and 2 hours. Patients were treated in a prone position, with the applicator placed directly over the area of interest. The treatment was entirely non-invasive, and patients did not need to remove their clothing. • Number of sessions : Median of 8 sessions (range: 1 – 10, mean: 7.1). • Number of pulses per session : Median of 15,000 pulses (range: 10,000 – 45,000, mean: 17,857). • Pain reduction : Median VAS reduction of 4 points (range: 0 – 8, mean: 3.7).
