Dose distribution for a representative patient with a 2.5 cm T3N0M0 stage IIB right lower lobe adenocarcinoma treated with standard RT technique. The patient was treated with carboplatin, paclitaxel, and thoracic RT to 63 Gy via six-field IMRT followed by an eight-field IMRT boost. The patient developed acute grade 2 dysphagia and grade 1 dyspnea and died 8 months after treatment from acute myocardial infarction without evidence of progression. (A) Axial dose distribution demonstrates high target volume conformality but inclusion of a significant volume of esophagus within the high dose–volume. A significant volume of lung received at least 5 Gy. (B) Coronal dose distribution. (C) Dose–volume histogram demonstrates high-esophageal V60 and high lung V5, V10, V20, and mean lung doses.
