Hypothesis
Can a nomogram based on radiomic and dosimetric parameters predict radiation esophagitis in patients with non-small cell lung cancer undergoing combined immunotherapy and radiotherapy?
Conclusion
The developed nomogram effectively predicts the occurrence of radiation esophagitis in patients with non-small cell lung cancer treated with immunotherapy and radiotherapy.
Supporting Evidence
- 38 out of 102 patients developed radiation esophagitis.
- The nomogram showed an AUC of 0.918 in the training cohort.
- Independent predictors included maximum dose to the esophagus >58.4 Gy and mean esophagus dose >13.3 Gy.
- The model demonstrated good calibration and clinical effectiveness.
Takeaway
Doctors can use a special chart to help figure out which lung cancer patients might get a sore throat from radiation treatment, so they can take steps to prevent it.
Methodology
The study analyzed data from 102 patients, using logistic regression to identify predictors of radiation esophagitis and developing a nomogram based on significant factors.
Potential Biases
Selection bias may be present due to the retrospective nature of the study.
Limitations
The study is retrospective, single-center, and has a relatively small sample size.
Participant Demographics
Of the 102 patients, 86.3% were male and 42.2% were aged 60 or younger.
