Early Interventional Treatments for Patients with Cancer Pain: A Narrative Review

Area of Science:

• Oncology
• Pain Management
• Interventional Radiology

Background:

• 10-20% of cancer patients experience pain inadequately controlled by WHO's three-step ladder.
• Refractory cancer pain necessitates advanced treatment strategies beyond conventional analgesics.

Purpose of the Study:

• To review evidence on interventional treatments for refractory cancer pain.
• To compare the efficacy and outcomes of early versus late indications for these procedures.

Main Methods:

• Systematic search for studies on interventional techniques for cancer pain.
• Narrative review and analysis of available evidence, focusing on timing of intervention.

Main Results:

• Strong evidence supports the efficacy of procedures like neurolysis, vertebroplasty, kyphoplasty, and intrathecal drug delivery.
• These interventions decrease symptom burden, reduce opioid consumption, and improve quality of life.
• Evidence comparing early versus late intervention timing is scarce and of low quality.

Conclusions:

• Interventional techniques are effective for refractory cancer pain and may positively impact survival.
• Early consideration of interventional options is suggested, rather than reserving them as a last resort.
• Further high-quality research is needed to guide optimal timing for interventional cancer pain management.
