Accumulating evidence indicates that fractionated radiotherapy (RT) can result in distant non-irradiated (abscopal) tumour regression. Although preclinical studies indicate the importance of T cells in this infrequent phenomenon, these studies do not preclude that other immune mechanisms exhibit an addition role in the abscopal effect. We therefore addressed the question whether in addition to T cell mediated responses also humoral anti-tumour responses are modulated after fractionated RT and whether systemic dendritic cell (DC) stimulation can enhance tumour-specific antibody production.

Purpose: As Radiation-Induced Lung Toxicity (RILT) is dose-limiting for radiotherapy (RT) of lung cancer and current parameters are only moderately associated with RILT, we sought for novel parameters associated with RILT.

Patients And Methods: In this prospective study, FDG-PET-CT scans were taken on days 0, 7 and 14 after initiation of high-dose RT in 18 patients with stage III non-small cell lung cancer. The maximal Standardized Uptake Value (SUV(max)) in the lung outside of the GTV was used as a measure of FDG uptake.
