A single pulsed dye laser treatment at the time of suture removal does not appear to have a beneficial effect on clinical scar appearance. The point of minimal benefit for such laser treatments may lie somewhere between one and three treatments.

Radiation dermatitis is a common adverse effect of radiotherapy (RT) in breast cancer patients. Although radiation dermatitis is reported by either the clinician or the patient, previous studies have shown disagreement between clinician-reported outcomes (CROs) and patient-reported outcomes (PROs). This review evaluated the extent of discordance between CROs and PROs for radiation dermatitis. Studies reporting both clinician and patient-reported outcomes for external beam RT were eligible. Nine studies met the inclusion criteria for the systematic review, while 8 of these studies were eligible for inclusion in a meta-analysis of acute and late skin toxicities. We found an overall agreement between CROs and PROs of acute skin colour change, fibrosis and/or retraction, and moist desquamation ( p > 0.005). Reporting of late breast pain, breast edema, skin colour change, telangiectasia, fibrosis and/or retraction and induration/fibrosis alone ( p > 0.005) were also in agreement between clinicians and patients. Our meta-analysis revealed a greater reporting of acute breast pain by patients (RR = 0.89, 95% CI 0.87–0.92, p < 0.001), greater reporting of acute breast edema by physicians (RR = 1.80, 95% CI 1.65–1.97, p < 0.001) and a greater reporting of late breast shrinkage by patients (RR = 0.61, 95% CI 0.44–0.86, p = 0.005). However, our review was limited by the discrepancies between PRO and CRO measurement tools as well as the absence of standard time points for evaluation of radiation dermatitis. Given potential discrepancies between CROs and PROs, both measures should be reported in future studies. Ultimately, we advocate for the development of a single tool to assess symptoms from both perspectives.
