It allows for precise targeting of the cancer while sparing healthy tissues, which can lead to better tumor control and fewer side effects.2381112
Do I have to stop taking my current medications for the trial?The trial protocol does not specify if you need to stop taking your current medications. However, if you are on a stable dose of a medication like warfarin and have no underlying coagulation issues, you may participate. It's best to discuss your specific medications with the trial team.
What data supports the idea that MRI-Guided Radiotherapy for Head and Neck Cancer is an effective treatment?The available research shows that MRI-Guided Radiotherapy, also known as Intensity-modulated radiation therapy (IMRT), is effective for treating head and neck cancer. It allows for higher doses of radiation to be delivered directly to the cancer while sparing healthy tissues, which can reduce side effects.

Experimental Treatment
Group I: Adaptive Radiotherapy treatmentExperimental Treatment2 Interventions
Patients will undergo adaptive radiotherapy boost for head/neck squamous cell carcinomas. A base conventional IMRT plan of 46-50Gy in 2 Gy to gross disease in the primary/nodes and 41.4-45 Gy in 1.8 Gy to the elective nodes per fraction will be utilized. The MR simulation will be utilized for boost treatment planning. Patients will receive their 6th fraction of the week on the adaptive platform treating the gross disease until completion of the base plan to 20 Gy in 2Gy daily fractions (10 fractions). Each ART treatment will be recontoured/replanned by the treating head/neck radiation oncologist as deemed clinically or dosimetrically necessary.

Intensity-modulated radiotherapy for carcinoma of the head and neck. [2019]Intensity-modulated radiotherapy (IMRT) is the next evolutionary step of three-dimensional conformal radiotherapy (3-DCRT). IMRT plans are generated with computer-optimized nonuniform radiation beam intensities incident on a target or patient. The dose distributions in IMRT show significantly higher conformality compared with other methods of external-beam radiation delivery, including conventional 3-DCRT. This significant conformality is advantageous in malignancies of the head and neck, where differential dosage is needed to deliver higher doses to the primary tumor and lower doses to areas of subclinical disease. Topics discussed in this review include target delineation, salivary gland sparing, and treatment of specific primary sites. Available data from the literature are presented, including patterns of failure after IMRT. To illustrate the potential role of IMRT in dose escalation and sparing of normal tissues, fractionation strategies in the definitive treatment of head and neck malignancies are presented. In addition, the role of IMRT in treatment of recurrent malignancies of the head and neck is explored. Finally, general concepts of helical tomotherapy are discussed.
Intensity-modulated radiation therapy for head and neck cancer. [2022]Intensity-modulated radiation therapy (IMRT) involves the delivery of optimized nonuniform beam intensities to the patient. In the head and neck region, there are many critical structures in close proximity to the target, with little influence from internal organ motion. Because IMRT produces tightly conformal doses and steep-dose gradients next to normal tissues, it provides the potential for organ sparing and improved tumor control. The dosimetric superiority of head and neck IMRT over conventional techniques has been demonstrated. The initial results of clinical IMRT studies showed reduction in xerostomia with no compromise in locoregional control if caution and appropriate knowledge are exercised in target determination and delineation.
Intensity-modulated radiation therapy in the management of head and neck cancer. [2019]Intensity-modulated radiation therapy (IMRT) represents a potentially significant new advance in the radiotherapeutic treatment of head and neck cancer patients. The capacity of IMRT to produce highly conformal dose distributions affords the opportunity to decrease the spectrum of toxicities associated with head and neck radiation. This review updates recent advances regarding the use of this emerging technology.
Intensity-modulated radiation therapy: emerging cancer treatment technology. [2018]The use of intensity-modulated radiation therapy (IMRT) is rapidly advancing in the field of radiation oncology. Intensity-modulated radiation therapy allows for improved dose conformality, thereby affording the potential to decrease the spectrum of normal tissue toxicities associated with IMRT. Preliminary results with IMRT are quite promising; however, the clinical data is relatively immature and overall patient numbers remain small. High-quality IMRT requires intensive physics support and detailed knowledge of three-dimensional anatomy and patterns of tumour spread. This review focuses on basic principles, and highlights the clinical implementation of IMRT in head and neck and prostate cancer.
Intensity-modulated radiation therapy in the treatment of head and neck cancer. [2018]Intensity-modulated radiation therapy (IMRT) is a new technical improvement of radiotherapy, in which computer-controlled treatment machines produce multiple beams of radiotherapy whose intensity is optimized to deliver a high dose of radiation to specified volumes, while reducing the dose to adjacent non-target organs. The potential benefits include the ability to deliver higher doses to the target with an improved safety than has previously been possible, and to reduce side effects and complications. Using IMRT to treat some head and neck cancers is especially attractive due to the close vicinity of the targets and many critical, dose-limiting and non-involved structures, and because of the lack of breathing-related motion. The main clinical uncertainties in the use of IMRT for head and neck cancer relate to uncertainties in the extent of radiation to the target areas. In addition, large volumes of adjacent, non-target tissue receive moderate to low radiation doses, raising concerns of increased risk of radiation-related carcinogenesis in young patients. Initial promising clinical data have emerged from IMRT treatment of several head and neck tumor sites.
Intensity-modulated radiotherapy for head and neck cancer. [2007]Intensity-modulated radiation therapy (IMRT) is a new radiation delivery technique that allows more precise delivery of radiation and optimization of the dose intensity to specific volumes while sparing the dose to critical normal structures. Using IMRT in head and neck cancers is attractive because of close proximity of the tumor targets to critical normal structures such as the spine, eyes, and parotid glands. IMRT has been shown in a number of clinical sites to improve local control and decrease side effects. Specifically, IMRT has shown the ability to preserve salivary function through sparing of the parotid glands. At the same time, there remain some uncertainties in terms of target delineation, secondary cancers, and side effects to swallowing function that may be increased with IMRT. Multi-institutional studies of IMRT are under way, and these studies, combined with refinements of the technique, should lead to continued improvement in the radiotherapeutic management of head and neck cancer.

Intensity-modulated radiation therapy for head and neck cancer: systematic review and meta-analysis. [2022]Intensity-modulated radiation therapy (IMRT) provides the possibility of dose-escalation with better normal tissue sparing. This study was performed to assess whether IMRT can improve clinical outcomes when compared with two-dimensional (2D-RT) or three-dimensional conformal radiation therapy (3D-CRT) in patients with head and neck cancer.
[Intensity modulated radiation therapy]. [2015]The development and successful clinical use of intensity modulated radiation therapy (IMRT) is a significant advance in radiation therapy. IMRT is particularly effective for cancers in complex anatomic regions such as the head and neck, and prostate, because the target volumes are contiguous to organs at risk. The success of IMRT strongly depends on the precise contouring of the target volumes and organs at risk. A significant benefit of IMRT with regard to xerostomia and quality of life has been reported for head and neck cancer. For prostate cancer, IMRT can deliver a high total dose of 76-80 Gy to the target volume without serious late toxicities.
