Effect of intensity-modulated radiation therapy on sciatic nerve injury caused by echinococcosis

Neural Regeneration Research, 2021
Conventional radiotherapy has a good killing effect on femoral echinococcosis. However, the sciatic nerve around the lesion is irreversibly damaged owing to bystander effects.

A network analysis of self‐reported psychoneurological symptoms in patients with head and neck cancer undergoing intensity‐modulated radiotherapy

Cancer, 2022
Patients with head and neck cancer experience psychoneurological symptoms (PNS) (i.e., depression, fatigue, sleep disturbance, pain, and cognitive dysfunction) during intensity‐modulated radiotherapy (IMRT) that decrease their functional status, quality ...
