Isolated limb perfusion with cytostatic drug leakage

Area of Science:

• Oncology
• Surgical Oncology
• Pharmacology

Background:

• Isolated limb perfusion (ILP) is a treatment for stage III melanoma with in-transit metastasis.
• ILP allows high-concentration, localized administration of chemotherapy agents, avoiding systemic toxicity.
• Systemic leakage of these agents is a significant complication, potentially causing systemic inflammatory response syndrome.

Observation:

• A case involving isolated lower limb perfusion for melanoma is presented.
• The procedure was interrupted due to the systemic passage of tumor necrosis factor.
• This passage led to severe intra-operative hemodynamic instability.

Findings:

• Systemic leakage of chemotherapy agents during ILP can manifest as systemic inflammatory response syndrome.
• Tumor necrosis factor release into systemic circulation can cause critical hemodynamic compromise.
• Early detection and multidisciplinary management are crucial for peri-operative safety.

Implications:

• This case highlights the critical importance of vigilant monitoring for systemic leakage during ILP.
• Anesthesiologists play a vital role in managing potential systemic complications of ILP.
• Understanding and mitigating ILP-related toxicities are essential for optimizing patient outcomes in advanced melanoma treatment.
