Endoscopic laser palliation for advanced malignant dysphagia

Area of Science:

• Gastroenterology
• Oncology
• Otolaryngology

Background:

• Malignant dysphagia significantly impacts quality of life in advanced cancer patients.
• Palliative treatment focuses on optimizing swallowing function and minimizing patient distress.
• Surgical options are often unsuitable for patients with advanced malignancy or prior unsuccessful surgeries.

Purpose of the Study:

• To evaluate the efficacy and safety of endoscopic Neodymium-doped Yttrium Aluminum Garnet (Nd:YAG) laser treatment for malignant dysphagia.
• To assess the impact of Nd:YAG laser therapy on swallowing function and patient outcomes.
• To determine the duration of palliation and identify factors influencing treatment success.

Main Methods:

• A cohort of 34 patients with malignant dysphagia, unsuitable for surgery, underwent endoscopic Nd:YAG laser treatment.
• Swallowing function was assessed using a 0-4 scale (0=normal, 4=complete dysphagia).
• Patient outcomes, including survival, need for re-treatment, and complications, were recorded.

Main Results:

• Significant improvement in swallowing was achieved in 29 patients (85%).
• The mean improvement in swallowing score was 1.7, with 74% able to swallow most or all solids post-treatment.
• Mean survival was 19 weeks; 18 patients required further treatment for recurrent dysphagia, with variable response.

Conclusions:

• Endoscopic Nd:YAG laser therapy is an effective palliative treatment for malignant dysphagia in carefully selected patients.
• While offering significant short-term improvement, recurrent dysphagia necessitates further interventions, including prosthetic tube insertion in some cases.
• The duration of palliation is variable, highlighting the need for individualized patient management.
