Hypothesis
Patients undergoing mediastinal radiotherapy may develop early oesophageal dysmotility.
Conclusion
Oesophageal scintigraphy can detect early alterations of oesophageal transit during the third week of thoracic radiotherapy.
Supporting Evidence
- 82% of patients showed an increase in the residual activity ratio during treatment.
- 63% of patients had a slight increase in mean transit time during irradiation.
- No patients developed grade 2 or 3 acute toxicity.
Takeaway
This study looked at how radiation therapy affects swallowing in patients. It found that many patients had changes in how their oesophagus worked during treatment.
Methodology
Oesophageal transit scans were performed on 11 patients at three time points during radiotherapy, measuring mean transit time and residual activity.
Limitations
The study lacked a comparison with manometry, which is the gold standard for detecting oesophageal motility issues.
Participant Demographics
All participants were male, with a mean age of 59 years.
