Abstract:
We evaluated acute toxicity and disease control in 42 patients receiving thoracic radiotherapy with concurrent KRAS G12C inhibitors. Toxicity included 13 grade 2 events (31%) and one grade 3 pneumonitis. There were no significant differences in toxicity between patients who held versus continued inhibitors during radiotherapy. The estimated cumulative incidence of local failure at 6 months was 5%.
