Objectives: This study evaluated for the first time in intraindividual comparison the conception of care with creme or powder. Acute skin reactions on the left and right side of the neck during symmetrically performed radiotherapy and subjective impairment were assessed.
Patients and methods: Twelve patients receiving radiotherapy of the head-and-neck region up to 50, 60, 66 and 72 Gy, respectively, were asked to treat one side of the neck with creme, the contralateral side with powder after random assignment. Objective and subjective assessment and photodocumentation were performed at therapy onset and weekly during therapy. The photodocumentation provides an impressive course of acute skin reactions under these care concepts.
Results: Altogether we saw no relevant difference in favor of care with creme or powder according to objective as well as subjective assessment criteria (Figure 2 and 3). In this intraindividual comparison the results are independent from interindividual different sensitivity to radiotherapy, total dose or fractionation. Therefore the small patient number is a minor limitation for evidence. Our results are in accordance to trials comparing other care concepts.
Conclusions: A relevant effect concerning onset and degree of acute skin reactions or differences in symptom relief could not be demonstrated. Both conceptions are to be regarded equal in terms of subjective symptom relief and in extent of acute skin reactions. The lack of differences may be explained by the fact that the underlying pathophysiological processes cannot be influenced by topical agents.
