The Treatment Outcome and Radiation-Induced Toxicity for Patients with Head and Neck Carcinoma in the IMRT Era: A Systematic Review with Dosimetric and Clinical Parameters

<table>A typical IMRT plan with the parotid sparing technique for a carcinoma of the oral cavity. Three PTVs were contouring: primary site and all relevant lymph nodes as PTV1; primary site and clinical involved lymph nodes as PTV2; primary site only as PTV3. The technique used was integrated boost by means of 30 fractions with 1.8 Gy, 2 Gy, and 2.25 Gy per fraction by PTV1, PTV2, and PTV3, respectively (ONCENTRA, treatment planning). The isodoses shown are the 95% of the prescribed doses per PTV: 45% in orange; 51.3% in blue; 57% in green; 64,13% in red (personal archive).</table>
