Applied radiation fields and dose of radiation (in Gy) in the group of CCS treated with H&N RT.
| Radiation Field | Total n (%) | Radiation Dose | |
|---|---|---|---|
| Mean (sd) | Median (Range) | ||
| Group 2: H&N RT | 94 (100.0) | 27.80 (17.91) | 25.00 (5.00–100.80) |
| RT to salivary glands a | 81 (86.2) | 25.17 (17.27) | 24.00 (5.00–100.80) |
| Full brain | 45 | 31.26 (11.99) | 25.00 (18.00–55.70) |
| Face | 8 | 46.69 (26.46) | 37.80 (25.00–100.80) |
| TBI | 29 | 9.33 (2.34) | 8.00 (5.00–12.00) |
| RT not to salivary glands b | 6 (6.4) | 33.20 (10.30) | 39.70 (19.80–40.00) |
| Unclear RT to salivary glands c | 7 (7.4) | 53.57 (3.58) | 54.00 (50.40–60.00) |
H&N RT; head/neck radiotherapy, TBI; total body irradiation. a One CCS received both TBI and RT to the brain. These dose values have been summed. b Field of irradiation was the neck. c Field of irradiation was part of the brain.
