Background We validated the new European Organisation for Research and Treatment of Cancer Quality of Life Head and Neck Module (EORTC QLQ‐HN43). Methods We enrolled 812 patients with head and neck cancer from 18 countries. Group 1 completed the questionnaire before therapy, and 3 and 6 months later. In group 2 (survivors), we determined test–retest reliability using intraclass correlation coefficients (ICC). Internal consistency was assessed using Cronbach's Alpha, the scale structure with confirmatory factor analysis, and discriminant validity with known‐group comparisons. Results Cronbach's alpha was >0.70 in 10 of the 12 multi‐item scales. All standardized factor loadings exceeded 0.40. The ICC was >0.70 in all but two scales. Differences in scale scores between known‐groups were >10 points in 17 of the 19 scales. Sensitivity to change was found to be sufficient in 18 scales. Conclusions Evidence supports the reliability and validity of the EORTC QLQ‐HN43 as a measure of quality of life.

Background: Herbal remedies used by patients for treatment of inflammatory bowel disease include slippery elm, fenugreek, devil’s claw, Mexican yam, tormentil and wei tong ning, a traditional Chinese medicine. Reactive oxygen metabolites produced by inflamed colonic mucosa may be pathogenic. Aminosalicylates (5‐ASA) are antioxidant and other such agents could be therapeutic. Aims: To assess the antioxidant effects of herbal remedies in cell‐free oxidant‐generating systems and inflamed human colorectal biopsies. Methods: Luminol‐enhanced chemiluminescence in a xanthine/xanthine oxidase cell‐free system was used to detect superoxide scavenging by herbs and 5‐ASA, and fluorimetry to define peroxyl radical scavenging using a phycoerythrin degradation assay. Chemiluminescence was used to detect herbal effects on generation of oxygen radicals by mucosal biopsies from patients with active ulcerative colitis. Results: Like 5‐ASA, all herbs, except fenugreek, scavenged superoxide dose‐dependently. All materials tested scavenged peroxyl dose‐dependently. Oxygen radical release from biopsies was reduced after incubation in all herbs except Mexican yam, and by 5‐ASA. Conclusions: All six herbal remedies have antioxidant effects. Fenugreek is not a superoxide scavenger, while Mexican yam did not inhibit radical generation by inflamed biopsies. Slippery elm, fenugreek, devil’s claw, tormentil and wei tong ning merit formal evaluation as novel therapies in inflammatory bowel disease.

Objectives: This study evaluates the interobserver variation in parotid gland delineation and its impact on intensity-modulated radiotherapy (IMRT) solutions. Methods: The CT volumetric data sets of 10 patients with oropharyngeal squamous cell carcinoma who had been treated with parotid-sparing IMRT were used. Four radiation oncologists and three radiologists delineated the parotid gland that had been spared using IMRT. The dose-volume histogram (DVH) for each study contour was calculated using the IMRT plan actually delivered for that patient. This was compared with the original DVH obtained when the plan was used clinically. Results: 70 study contours were analysed. The mean parotid dose achieved during the actual treatment was within 10% of 24 Gy for all cases. Using the study contours, the mean parotid dose obtained was within 10% of 24 Gy for only 53% of volumes by radiation oncologists and 55% of volumes by radiologists. The parotid DVHs of 46% of the study contours were sufficiently different from those used clinically, such that a different IMRT plan would have been produced. Conclusion: Interobserver variation in parotid gland delineation is significant. Further studies are required to determine ways of improving the interobserver consistency in parotid gland definition.
