Acute Toxicity and Quality of Life After Dose-Intensified Salvage Radiation Therapy for Biochemically Recurrent Prostate Cancer After Prostatectomy: First Results of the Randomized Trial SAKK 09/10

PURPOSE Patients with biochemical failure (BF) after radical prostatectomy may benefit from dose-intensified salvage radiation therapy (SRT) of the prostate bed. We performed a randomized phase III trial assessing dose intensification. PATIENTS AND METHODS Patients with BF but without evidence of macroscopic disease were randomly assigned to either 64 or 70 Gy. Three-dimensional conformal radiation therapy or intensity-modulated radiation therapy/rotational techniques were used. The primary end point was freedom from BF. Secondary end points were acute toxicity according to the National Cancer Institute Common Terminology Criteria for Adverse Events (version 4.0) and quality of life (QoL) according to the European Organisation for Research and Treatment of Cancer Quality of Life Questionnaires C30 and PR25. RESULTS Three hundred fifty patients were enrolled between February 2011 and April 2014. Three patients withdrew informed consent, and three patients were not eligible, resulting in 344 patients age 48 to 75 years in the safety population. Thirty patients (8.7%) had grade 2 and two patients (0.6%) had grade 3 genitourinary (GU) baseline symptoms. Acute grade 2 and 3 GU toxicity was observed in 22 patients (13.0%) and one patient (0.6%), respectively, with 64 Gy and in 29 patients (16.6%) and three patients (1.7%), respectively, with 70 Gy (P = .2). Baseline grade 2 GI toxicity was observed in one patient (0.6%). Acute grade 2 and 3 GI toxicity was observed in 27 patients (16.0%) and one patient (0.6%), respectively, with 64 Gy, and in 27 patients (15.4%) and four patients (2.3%), respectively, with 70 Gy (P = .8). Changes in early QoL were minor. Patients receiving 70 Gy reported a more pronounced and clinically relevant worsening in urinary symptoms (mean difference in change score between arms, 3.6; P = .02). CONCLUSION Dose-intensified SRT was associated with low rates of acute grade 2 and 3 GU and GI toxicity. The impact of dose-intensified SRT on QoL was minor, except for a significantly greater worsening in urinary symptoms.

Planning and reporting of quality-of-life outcomes in cancer trials.

BACKGROUND Information about the impact of cancer treatments on patients' quality of life (QoL) is of paramount importance to patients and treating oncologists. Cancer trials that do not specify QoL as an outcome or fail to report collected QoL data, omit crucial information for decision making. To estimate the magnitude of these problems, we investigated how frequently QoL outcomes were specified in protocols of cancer trials and subsequently reported. DESIGN Retrospective cohort study of RCT protocols approved by six research ethics committees in Switzerland, Germany, and Canada between 2000 and 2003. We compared protocols to corresponding publications, which were identified through literature searches and investigator surveys. RESULTS Of the 173 cancer trials, 90 (52%) specified QoL outcomes in their protocol, 2 (1%) as primary and 88 (51%) as secondary outcome. Of the 173 trials, 35 (20%) reported QoL outcomes in a corresponding publication (4 modified from the protocol), 18 (10%) were published but failed to report QoL outcomes in the primary or a secondary publication, and 37 (21%) were not published at all. Of the 83 (48%) trials that did not specify QoL outcomes in their protocol, none subsequently reported QoL outcomes. Failure to report pre-specified QoL outcomes was not associated with industry sponsorship (versus non-industry), sample size, and multicentre (versus single centre) status but possibly with trial discontinuation. CONCLUSIONS About half of cancer trials specified QoL outcomes in their protocols. However, only 20% reported any QoL data in associated publications. Highly relevant information for decision making is often unavailable to patients, oncologists, and health policymakers.

Owner-perceived, weighted quality-of-life assessments in dogs with spinal cord injuries.

OBJECTIVE To evaluate changes over time in owner-perceived, weighted quality-of-life assessments in dogs with spinal cord injuries and determine whether scores were associated with underlying etiology or with veterinarian-assigned scores for severity of neurologic dysfunction. DESIGN Cohort study. ANIMALS 100 dogs with spinal cord injury. PROCEDURES Duration of dysfunction, modified Frankel neurologic injury score, and etiology were recorded. At initial and recheck (4- to 6-week) evaluations, owners were asked to identify 5 areas or activities they believed had the most influence on their dogs' quality of life, assess their dogs' current status in each area, and provide a weighting for the importance of each area; results were used to construct a weighted quality-of-life score. Owners were also asked to provide a quality-of-life score with a visual analog scale (VAS). RESULTS At initial and recheck evaluations, weighted quality-of-life scores were higher for ambulatory than for nonambulatory dogs. However, scores did not differ among groups when dogs were grouped on the basis of underlying etiology or duration of injury. Dogs with an increase in Frankel score between the initial and recheck evaluations had a significant increase in weighted quality-of-life score, whereas for dogs that did not have any change in Frankel score, initial and recheck weighted quality-of-life scores were not significantly different. CONCLUSIONS AND CLINICAL RELEVANCE Results suggested that owner-assigned, weighted quality-of-life scores for dogs with spinal cord injuries did not vary significantly on the basis of underlying etiology or duration of injury but were higher for ambulatory than for nonambulatory dogs.

Evaluation of a questionnaire for obtaining owner-perceived, weighted quality-of-life assessments for dogs with spinal cord injuries.

OBJECTIVE To evaluate a questionnaire for obtaining owner-perceived, weighted quality-oflife assessments for dogs with spinal cord injuries. DESIGN Evaluation study. Animals-100 dogs with spinal cord injuries and 48 healthy control dogs. PROCEDURES The questionnaire was adapted from a questionnaire (the schedule for the evaluation of individual quality of life-direct weighting) used for human patients. Specifically, owners were asked to identify 5 areas or activities they believed had the most influence on their dogs' quality of life, assess their dogs' current status in each of those areas, and provide a weighting for the importance of each area. Results were used to construct a weighted quality-of-life score ranging from 0 to 100 for each dog. Owners were also asked to provide a quality-of-life score with a visual analog scale (VAS). RESULTS A good correlation was found between weighted and VAS quality-of-life scores. Dogs with spinal cord injuries had weighted quality-of-life scores that were significantly lower than scores for control dogs. Quality-of-life areas and activities provided by owners of dogs with spinal cord injuries were similar to areas and activities provided by owners of healthy control dogs and could mostly be encompassed by 5 broader domains: mobility, play or mental stimulation, health, companionship, and other. CONCLUSIONS AND CLINICAL RELEVANCE Results suggested that the questionnaire could be used to obtain owner-perceived, weighted quality-of-life assessments for dogs with spinal cord injuries. Obtaining owner-perceived quality-of-life assessments for individual dogs should allow veterinarians to better address quality-of-life concerns and expectations of owners.

Quality of Life in Swiss Paediatric Inflammatory Bowel Disease Patients: Do Patients and Their Parents Experience Disease in the Same Way?

BACKGROUND AND AIMS Inflammatory bowel diseases (IBDs) may impair quality of life (QoL) in paediatric patients. We aimed to evaluate in a nationwide cohort whether patients experience QoL in a different way when compared with their parents. METHODS Sociodemographic and psychosocial characteristics were prospectively acquired from paediatric patients and their parents included in the Swiss IBD Cohort Study. Disease activity was evaluated by the Paediatric Crohn's Disease Activity Index (PCDAI) and the Paediatric Ulcerative Colitis Activity Index (PUCAI). We assessed QoL using the KIDSCREEN questionnaire. The QoL domains were analysed and compared between children and parents according to type of disease, parents' age, origin, education and marital status. RESULTS We included 110 children and parents (59 Crohn's disease [CD], 45 ulcerative colitis [UC], 6 IBD unclassified [IBDU]). There was no significant difference in QoL between CD and UC/IBDU, whether the disease was active or in remission. Parents perceived overall QoL, as well as 'mood', 'family' and 'friends' domains, lower than the children themselves, independently of their place of birth and education. However, better concordance was found on 'school performance' and 'physical activity' domains. Marital status and age of parents significantly influenced the evaluation of QoL. Mothers and fathers being married or cohabiting perceived significantly lower mood, family and friends domains than their children, whereas mothers living alone had a lower perception of the friends domain; fathers living alone had a lower perception of family and mood subscores. CONCLUSION Parents of Swiss paediatric IBD patients significantly underestimate overall QoL and domains of QoL of their children independently of origin and education.
