Photographic documentation of acute radiation-induced side effects of the oral mucosa.
BACKGROUND
Radiotherapy in cancer of the head and neck induces cutaneous and mucosal reactions. These must be carefully assessed and documentated to control the accuracy of individual treatment, the overall toxicity of particular treatment schedules, the efficacy of prophylaxis and treatment and to determine the adequate therapy of treatment sequelae depending on the severity of the reactions. The accurate classification of lesions according to internationally accepted schedules (WHO/RTOG/CTC) is indispensable for the comparison of radiotherapy treatment results and efficacy of supportive care.


METHODS
While the treatment of cancer depends on tumor stage and medical circumstances of the patient and is more or less standardized, prophylaxis and treatment of side-effects is highly variable. Discussing an optimized prophylaxis and therapy of oral mucositis, the problem of accurate classification and documentation emerged. The verbal description of mucosal lesions is open to many subjective interpretations. Photographic documentation seems a suitable method to optimize the grading of toxicity.


RESULTS
A photographic survey of typical lesions for each grade of toxicity is a tool to reach several aims in one step. Toxicity of an individual patient may be compared with representative photographic examples in daily routine to decide quickly on the grade of toxicity. Subjective differences due to intra- and interpersonal variability of the evaluating radiooncologist will be reduced. The efficacy of treatment can be proven by accurate documentation. Randomized clinical studies concerning prophylaxis and treatment of oral mucositis will provide more reliable results if evaluation of toxicity grading is standardized by photographs.


CONCLUSIONS
Photographic documentation of lesions of the oral mucosa might be the best means to reduce interindividual subjectivity in grading. It is a valuable appendix to standard classification systems and only concerns the visible signs of mucosal lesions. However, the exact grading of mucositis is only possible with additional clinical information about pain and nutritional situation.
