Description: <p><b>Extracorporeal Shock Wave Therapy</b> - Underwater / Focused Shock Wave Treatment</p>
<p><b>Recommended Abbreviation:</b> ESWT</p>
<p><b>Alternative Names:</b> Extracorporeal shock waves, ESW, shock wave therapy, underwater shock waves, focused shock wave therapy</p>
<p><b>Type:</b> Physical therapy / acoustic-mechanical intervention / experimental anticancer treatment</p>
<p><b>Function:</b> Extracorporeal shock waves are high-pressure acoustic pulses transmitted through a material medium into biological tissue. Shock waves produce rapid mechanical stress, pressure gradients, cavitation-related effects, and transient increases in cell-membrane permeability. Depending on energy and treatment parameters, these effects can alter cellular signaling, drug uptake, vascular responses, apoptosis, and tissue remodeling.</p>
<p><b>Cancer:</b> Preclinical studies demonstrate direct cytotoxic and pro-apoptotic effects in multiple cancer models and increased tumor-cell permeability to anticancer drugs and other therapeutic molecules. Shock waves can enhance the cytotoxic activity of agents including cisplatin, doxorubicin, bleomycin, and paclitaxel and have been investigated for drug delivery and sonodynamic approaches. Direct shock-wave treatment of malignant tumors remains experimental and is not an established standard cancer therapy.</p>
<p><b>Clinical Status:</b> Established extracorporeal shock wave therapy is primarily used for musculoskeletal and rehabilitation indications. Active malignant tissue within the treatment field is generally considered a contraindication for routine clinical ESWT, despite experimental research investigating direct antitumor applications.</p>
