Comparative Effectiveness and Safety of Radiotherapy Treatments for Head and Neck Cancer

Slide: 17 of 36

Interventions of Interest

Studies that used a mix of radiotherapy modalities, such as 2DRT plus IMRT boost or 3DCRT plus brachytherapy, were excluded from the review. Boost techniques were allowed if they were of the same modality as the main technique (e.g., IMRT with an IMRT boost). Conventional 2DRT was addressed to the extent that comparative studies included groups of patients who received 2DRT. However, noncomparative studies of 2DRT were not sought. Data on other comparators, such as stereotactic radiosurgery or similar modalities, were also not sought.
