IMRT with Compensators for Head-and-Neck Cancers

Optimization strategies for pulsed low‐dose‐rate IMRT of recurrent lung and head and neck cancers

Pulsed low-dose-rate radiotherapy (PLDR) has been proven to be a valid method of reirradiation. Previous studies of recurrent cancer radiotherapy were mainly based on conventional 3D CRT and VMAT delivery techniques. There are difficulties in IMRT planning using existing commercial treatment planning systems (TPS) to meet the PLDR protocol. This work focuses on PLDR using ten-field IMRT and a c...

Effect of cryotherapy on oral mucositis in patients with head and neck cancers receiving radiotherapy

Background: Mucositis is an important adverse effect of cancer treatment. The aim of this study was to investigate the effect of ice cubes on oral mucositis following head and neck radiotherapy. Materials and Methods: A randomized controlled trial was conducted on 40 head and neck cancer patients who underwent radiotherapy. The patients were randomly divided into two experimental and control gr...

Ultrasonographic changes of submandibular glands in irradiated patients for head and neck cancers

Background: Salivary glands (SGs) are usually irradiated during radiotherapy for head and neck cancers, which may lead to radiation-induced changes. These changes could be evaluated safely by ultrasonography; however, there have been few studies in this regard. Thus, we aimed to investigate the changes in post-radiotherapy submandibular glands using ultrasonography in patients undergoing head-n...

Postoperative IMRT in head and neck cancer

BACKGROUND Aim of this work was to assess loco-regional disease control in head and neck cancer (HNC) patients treated with postoperative intensity modulated radiation therapy (pIMRT). For comparative purposes, risk features of our series have been analysed with respect to histopathologic adverse factors. Results were compared with an own historic conventional radiation (3DCRT) series, and with...
