Should regional ventilation function be considered during radiation treatment planning to prevent radiation-induced complications?
The authors' results demonstrated that the inclusion of regional ventilation function improved accuracy in predicting RF. In particular, dose-subvolume metrics provided a promising method for preventing radiation-induced pulmonary complications.
Patients with colorectal cancer are at greater risk of developing a metachronous colorectal cancer. Among them, no predicting factors for the development of metachronous tumours were found. Thus lifelong colonoscopic surveillance is needed.
