Summary
Smoking during or after radiotherapy significantly prolongs mucositis duration in head and neck cancer patients. Quitting smoking before treatment is crucial for minimizing radiation-induced mucositis.
Area of Science:
- Oncology
- Radiotherapy
- Head and Neck Cancer Treatment
Background:
- Mucositis is a common and debilitating side effect of radiotherapy.
- Continuous, hyperfractionated, accelerated radiotherapy (CHART) is used for locally advanced head and neck cancer.
Purpose of the Study:
- To investigate the relationship between smoking patterns and the duration of mucositis in patients undergoing CHART.
- To identify factors influencing mucositis duration.
Main Methods:
- Analysis of smoking habits in 41 patients receiving CHART for head and neck cancer.
- Correlation analysis of smoking status, irradiated mucosal volume, and mucositis duration.
Main Results:
- No correlation found between mucositis duration and age, sex, or pre-treatment weight loss.
- Significant correlation between smoking during/after treatment and mucositis duration (p=0.014).
- Significant correlation between irradiated mucosal volume and mucositis duration (p=0.025).
Conclusions:
- Smoking during and/or after radiotherapy independently increases mucositis duration.
- Encouraging complete smoking cessation prior to radiotherapy is vital to minimize mucositis.
- Irradiated mucosal volume is another key factor influencing mucositis duration.
