Hypofractionated proton beam therapy for centrally located lung cancer.
This study from Japan reported outcomes of 39 patients who received hypofractionated PBT for centrally located cT1-2N0M0. Twenty-four patients (62%) were treated with 80 Gy (RBE) in 20 fractions, whereas eight (21%) were treated with 66 Gy (RBE) in 10 fractions. The 2-year progression-free survival (PFS) and overall survival (OS) rates were 86 and 100% for T1 disease and 56 and 94% for T2 disease.
Dyspnoea of grade 3 was noted in one patient (3%), and pneumonitis of grade 2 was noted in four patients (10%). The authors concluded that hypofractionated PBT may be a very safe and effective treatment option for centrally located early lung cancer.
