Malignant pleural effusions, causing shortness of breath, are effectively treated with thoracoscopic talc poudrage, achieving over 90% success. This procedure induces pleural symphysis, though rare complications like adult respiratory distress syndrome (ARDS) are linked to small talc particles.

Area of Science:

  • Pulmonology
  • Oncology
  • Thoracic Surgery

Context:

  • Malignant pleural effusions occur in approximately 20% of cancer patients.
  • Large effusions primarily cause dyspnea, along with cough and chest pain, influenced by effusion size and patient's pulmonary function.

Purpose:

  • To evaluate the efficacy and safety of thoracoscopic talc poudrage for managing malignant pleural effusions.
  • To discuss patient selection criteria and potential complications associated with talc pleurodesis.

Summary:

  • Thoracoscopic talc poudrage (2.5-10 g) is a highly effective therapy (>90% success rate) for controlling recurrent malignant pleural effusions.
  • Talc induces pleural inflammation and fibrosis, leading to symphysis. The procedure is suitable for patients in good condition with expected survival >30 days (Karnofsky Performance Scale ≥40).

  • Adult respiratory distress syndrome (ARDS) is a significant complication (up to 9%), particularly associated with small talc particles (<15 microm).

    • Impact:

    • Talc poudrage or slurry (particle size >10 microm) offers a safe and effective method for inducing pleural symphysis in malignant pleural effusions.
    • Complications like chest pain, fever, and empyema are rare and typically linked to the procedure itself.
