RTOG, CTCAE and WHO criteria for acute radiation dermatitis correlate with cutaneous blood flow measurements

Abstract Background Various clinician-assessed scoring criteria have been used to grade acute radiation dermatitis. However, it is not known whether these scoring criteria correlate with changes in objective skin biophysical parameters and patient-reported symptoms following radiotherapy. We seek to...

Description
Summary:Abstract Background Various clinician-assessed scoring criteria have been used to grade acute radiation dermatitis. However, it is not known whether these scoring criteria correlate with changes in objective skin biophysical parameters and patient-reported symptoms following radiotherapy. We seek to correlate three different clinician-assessed scoring criteria with skin biophysical changes and patient-reported symptoms in breast cancer patients undergoing radiotherapy. Methods A prospective cohort study was performed in a university hospital medical center. The severity of acute radiation dermatitis in 101 breast cancer patients was graded using the RTOG, CTCAE and WHO clinical scoring criteria. We also measured various skin biophysical parameters (skin blood flow, pigmentation, hydration, and pH) by non-invasive techniques before and after radiotherapy. Patient-reported breast symptoms (pain, itching, local heat, and tightness) were evaluated using a questionnaire. Results The three different clinician-assessed scoring criteria correlated most strongly with changes in cutaneous blood flow following radiotherapy for breast cancer (correlation coefficient 0.70 for RTOG, 0.68 for CTCAE, and 0.50 for WHO). All three scoring criteria also showed moderate correlation with changes in skin pigmentation (correlation coefficients 0.4–0.5), but showed no significant correlation with skin hydration or pH (correlation coefficients
