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

External-Beam Radiation Therapy for Head and Neck Cancer

Two-Dimensional Radiation Therapy and Three-Dimensional Conformal Radiation Therapy

This slide includes a table with two columns and four rows. Column 1, row 1: potential advantages. Column 2, row 1: potential disadvantages.Column 1, row 2: Higher dose delivered to tumor. Column 2, row 2: Higher total body dose. Column 1, row 3: Sparing of normal, surrounding tissue from radiation damage. Column 2, row 3: Increased risk of marginal miss and dose perturbation. Column 1, row 4: Decreased toxicity. Column 2, row 4: time and expense. A definition of abreviations is included on the slide: IMRT = intensity-modulated radiation therapy; 2DRT = two-dimensional radiation therapy; 3DCRT = three-dimensional conformal radiation therapy.
