Table 6 Radiotherapy doses for whole lung radiotherapy

Whole lung radiotherapy

The dose for whole lung radiotherapy is 15 Gy in 10 fractions for patients <14 years, or 18 Gy in 12 fractions for patients ≥14 years. Dose may be specified to 100 % for an optimised plan, or to the mid plane dose (MPD) for simulated opposed fields. However, it should be noted that this will result in a dose of approximately 10 % higher in the lungs than that prescribed, and so optimisation of dosimetry is recommended if fields are simulated
