Summary
High-dose-rate intraluminal brachytherapy (HDRILBT) combined with YAG laser effectively palliated obstructive colon cancer when surgery or stenting was not feasible. This novel approach improved tumor patency and relieved patient symptoms.
Area of Science:
- Oncology
- Gastroenterology
- Radiation Oncology
Background:
- Obstructive colon cancer palliation presents challenges, with limited options when standard treatments like stenting or surgery are not viable.
- High-dose-rate intraluminal brachytherapy (HDRILBT) has shown efficacy in palliating other luminal cancers.
Observation:
- A case of obstructive colon cancer at the hepatic flexure, unsuitable for stent placement or surgery, was treated with YAG laser followed by HDRILBT.
- The procedure involved endoscopic and fluoroscopic guidance for catheter placement and delivery of HDRILBT fractions.
Findings:
- Following HDRILBT, significant tumor shrinkage and increased colonic lumen patency were observed.
- The patient experienced substantial symptom relief, weight gain, and improved fitness for chemotherapy.
Implications:
- Combined YAG laser and HDRILBT offers a viable alternative for obstructive colon cancer palliation in select cases.
- This treatment approach may be considered when conventional methods are contraindicated, improving patient outcomes.
