Mean radiation dose to stomach from specific radiotherapy fields for Hodgkin lymphoma with at least some subdiaphragmatic exposure, by stomach site. All radiotherapy fields with exclusively supradiaphragmatic exposure gave mean dose to all stomach sites < 2 Gy, including mantle with lower border at diaphragm (51% cases, 55% controls; mean total stomach dose, 1.3 Gy), mediastinum (21% cases, 24% controls; mean, 0.8 Gy), supraclavicular (10% cases, 7% controls; mean, 0.1 Gy), axilla (17% cases, 16% controls; mean, 0.5 Gy), neck with or without head (37% cases, 27% controls; mean, 0.2 Gy), and other neck/chest (9% cases, 7% controls; mean, 0.4 Gy). (*) Percentages were calculated among patients who received radiotherapy (82 cases, 164 controls). Patients may have received multiple treatment fields.
