What Researchers Did
Researchers evaluated the effectiveness of interstitial low-dose-rate brachytherapy as a salvage treatment for 220 patients with recurrent head-and-neck cancers that had previously been treated with radiation.
What They Found
They found that local tumor control was achieved in 77% (217/282) of implanted sites. The 2, 5, and 10-year disease-free survival rates for the entire group were 60%, 33%, and 22% respectively, with an overall 5-year survival rate of 21.7%. However, 27% of patients experienced moderate to severe late complications.
What This Means for Canadian Patients
For Canadian patients facing recurrent head-and-neck cancers after prior radiation, this study suggests that brachytherapy can be an effective salvage treatment option. It offers a chance for local tumor control and improved survival, even in challenging cases where other options may be limited.
Canadian Relevance
No direct Canadian connection identified.
Study Limitations
This study is a retrospective analysis from a single institution, which may limit the generalizability of its findings.
