Parameters affecting laser palliation in patients with advanced digestive cancers

Area of Science:

• Oncology
• Gastroenterology
• Surgical Oncology

Background:

• Nonsurgical management of advanced cancers often requires palliative interventions.
• Dysphagia in esophagogastric cancer and rectal discharge/occlusion in rectosigmoid cancer significantly impact patient quality of life.
• Laser therapy presents a minimally invasive option for symptom palliation in these conditions.

Purpose of the Study:

• To evaluate the efficacy and safety of laser therapy for palliative treatment of dysphagia in esophagogastric cancer.
• To assess the effectiveness of laser therapy in palliating abnormal rectal discharge and occlusion in rectosigmoid cancer.
• To identify factors influencing the success and duration of palliation.

Main Methods:

• Retrospective analysis of 99 patients with esophagogastric cancer (Group I) and 142 with rectosigmoid cancer (Group II) undergoing laser therapy.
• Patients received monthly retreatment as needed.
• Success rates, duration of palliation, and complication rates were recorded and analyzed.

Main Results:

• Immediate success rates were 83% for esophagogastric cancer and 90% for rectosigmoid cancer.
• Average palliation duration was 4.3 months (Group I) and 9.3 months (Group II).
• Complication rates were low (4% in Group I, 3.4% in Group II). Factors like tumor size, location, and prior treatment affected outcomes in Group I.

Conclusions:

• Laser therapy is an effective palliative treatment for dysphagia and rectal symptoms in advanced esophagogastric and rectosigmoid cancers.
• Tumor characteristics significantly influence treatment outcomes in esophagogastric cancer patients.
• The procedure demonstrates a favorable safety profile and provides meaningful symptom relief and improved quality of life.
