- Abstract
Context: Longitudinal symptom monitoring is important in the setting of patients with advanced cancer. Scores over time may naturally fluctuate, although a patient may feel the same., Objectives: The purpose of this study was to determine the minimal levels of change required to be clinically relevant (minimal clinically important difference [MCID]) using the Edmonton Symptom Assessment System (ESAS)., Methods: Between 1999 and 2009, patients completed the ESAS before palliative radiotherapy and at follow-up. MCIDs were calculated using both the anchor- and distribution-based methods for improvement and deterioration; 95% confidence intervals for the differences in mean change scores between adjacent categories also were calculated., Results: A total of 276 patients completed the ESAS at baseline and during at least one follow-up visit. At the four-week follow-up, decrease of 1.2 and 1.1 units in pain and depression scales, respectively, constituted clinically relevant improvement, whereas increase of at least 1.4, 1.8, 1.1, 1.1, and 1.4 units, respectively, in pain, tiredness, depression, anxiety, and appetite loss items were required for deterioration. At the subsequent follow-ups, these values were similar. Overall, the MCID for improvement tended to be smaller than that for deterioration. The distribution-based method estimates tended to be larger than the 0.3 SD estimates, but closer to the 0.5 SD estimates., Conclusion: MCIDs allow health care professionals to determine the success of treatment in improving the patient's quality of life. MCIDs may prompt health care professionals to intervene with new treatment. Future studies should confirm our findings with a variety of anchors., (Copyright © 2013 U.S. Cancer Pain Relief Committee.

- Abstract
Purpose: The purpose of this study is to compare self-reported quality of life (QOL) scores in old and young patients with metastatic cancer using the European Organization for Research and Treatment of Cancer (EORTC) QLQ-C15-PAL questionnaire., Materials and Methods: Patients receiving palliative radiotherapy (RT) for bone metastases and brain metastases completed the QLQ-C15-PAL questionnaire prior to treatment. Using multiple linear regression analysis, a parametric test, the QLQ-C15-PAL scores were compared using 65 and 70 years as cutoff ages., Results: A total of 340 patients were referred for palliative RT for bone metastases (n = 190) or brain metastases (n = 150). Physical functioning and appetite were worse in the older group using either 65 or 70 years as the cutoff age. Age-related differences in the QLQ-C15-PAL scores varied as a function of age cutoff used and location of metastatic site irradiated., Conclusion: Based on the (EORTC) QLQ-C15-PAL, elderly advanced cancer patients have a different QOL profile. Similar observations have been reported with the (EORTC) QLQ-C30 questionnaire.

- Abstract
Purpose: To examine the reported rates and predictive factors for sleep disturbance in patients with bone metastases., Methods: Patients with symptomatic bone metastases treated with palliative radiotherapy (RT) were eligible. At initial consultation, demographic information, baseline Brief Pain Inventory (BPI) questionnaire, and analgesic consumption were recorded. The BPI functional interference sleep item was categorized into none (0), mild (1-3), moderate (4-6), and severe (7-10). Follow-up BPI was collected in person or via telephone post-RT at week 4, 8, and 12. Subgroup analysis for BPI between responders and nonresponders was performed. Ordinal logistic regression analysis was used to search for the relationship between sleep disturbance and other covariates., Results: Four hundred patients were enrolled between May 2003 and June 2007. Two hundred thirty-five males (59%) were accrued. The median age was 68 years old (range, 30-91). Within the study population, primary cancer sites included breast (25%), lung (25%), prostate (24%), bladder (4%), pancreas/gastric (3%), and other primaries (18%). In the BPI functional interference items, the mean baseline score for sleep disturbance was 4.8. When categorized in terms of severity, 99 (25%) patients had moderate sleep disturbance and 144 (36%) patients had severe sleep disturbance, respectively. There was an improvement in sleep scores for both responders and nonresponders at week 4 and 8, but scores worsened for nonresponders at week 12., Conclusion: Age, Karnofsky Performance Scale (KPS), pain score, and lung primary were the significant variables associated with sleep disturbance. The scores for sleep disturbance improved significantly post-RT in responders at week 4 and 12.

- Abstract
Background: Few studies incorporate patient self-assessment scales in prognostic models of survival prediction. The Edmonton Symptom Assessment Scale (ESAS) is commonly used as a symptom screening tool in cancer patients., Objective: The goal of this study was to evaluate the prognostic value of the ESAS for survival prediction in the advanced cancer population., Materials and Methods: Patients completed the ESAS and demographic information prior to palliative radiotherapy consultation and at follow-up at the Odette Cancer Centre between 1999 and 2009. Generalized estimating equation (GEE) methodology was applied to analyze ESAS trends within the last months of life. One-way analysis of variance (ANOVA) with repeated measurements was used to characterize trends between time periods., Results: ESAS records (2377) from 808 patients (433 male and 375 female) were included in this cohort. Median age was 68 years (range 32-95) with median Karnofsky performance status (KPS) of 60 (range 10-100). Primary cancer sites were of the lung (36%), breast (20%), and prostate (19%). All nine ESAS symptoms significantly deteriorated in the last 4 weeks immediately before death when compared with those scores in the preceding months. At one week prior to death, the worst ESAS symptoms experienced by patients were fatigue, appetite, and well-being with mean scores of 7.4, 6.9, and 6.1, respectively., Conclusions: All ESAS scores significantly worsened in the last 4 weeks prior to death compared with those in the previous months. Sudden deterioration of the global ESAS symptoms may predict impending death. Future studies on a prognostic model should incorporate both ESAS symptom severity and trends.
