Patients with head and neck cancer who are treated with radiotherapy often have significant
weight loss or tumor regression during treatment. Adaptive radiotherapy refers to acquiring …

Objective: The present study evaluated the efficacy and toxicity of adaptive radiotherapy
(RT) among patients with head and neck cancer. Methods: 36 patients eligible for radical RT …

Modern radiation therapy techniques are characterized by high conformality to tumor
volumes and steep dose gradients to spare normal organs. These techniques require …

Background Although there have been dramatic improvements in radiotherapy for head and
neck squamous cell carcinoma (HNSCC), including robust intensity modulation and daily …

Objective: To investigate the effects of adaptive radiotherapy on dosimetric, clinical, and
toxicity outcomes for patients with head and neck cancer undergoing chemoradiotherapy …

Background: Adaptive radiotherapy is being used in few institutions in patients with head
and neck cancer having bulky disease using periodic computed tomography imaging …

Introduction Head and neck cancer (HNC) patients' anatomy may undergo significant
changes during radiotherapy (RT). This potentially affects dose distribution and …

Abstract Changes in patient anatomy may occur either from a tumour volume, position or
function of a specific organ at risk, or target volume, weight loss or a reduction in …

Current head and neck intensity‐modulated radiotherapy (IMRT) techniques cause
significant toxicity. This may be explained in part by the fact that IMRT cannot compensate …

The aim of the review was to present the current literature status about replanning regarding
anatomical and dosimetric changes in the target and OARs in the head and neck region …
