[PMID: 37862371 DOI: 10.1080/0284186x.2023.2271165] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/09/2023] [Accepted: 10/10/2023] [Indexed: 10/22/2023]
Abstract
BACKGROUND Normative health-related quality of life (HRQoL) data from the general population are regularly used to facilitate the interpretation of HRQoL as reported by cancer patients participating in cancer clinical trials, especially when conducting long-term follow-up studies after treatment. The aim of the present study is to compare two Swedish normative data sets, published in 2000 and 2019 respectively, and explore whether HRQoL as reported by the Swedish general population has changed over time. MATERIAL AND METHODS 'Sample 2000' was comprised of normative data from the Swedish general population who responded to the EORTC QLQ-C30 in a Swedish mail survey in 1999 (n = 3069). 'Sample 2019' consisted of data from the Swedish general population collected as part of a European norm data study using online panels, published in 2019 (n = 1027). Data were analyzed stratified by sex and age (40-49; 50-59; 60-69; 70-79 years). RESULTS For most of the subscales and single items, no age group differences between the two samples were found, with the exception of the oldest age group (70-79 years), where Sample 2019 generally showed better HRQoL as compared to Sample 2000. Lower (worse) levels of Global quality of life and higher (worse) levels of Dyspnoea were found in Sample 2019 for most age groups. CONCLUSION There were no differences found between the samples for most EORTC QLQ-C30 subscales and single items, with the exception of the oldest age group of both sexes in Sample 2019 who reported better HRQoL on many variables. When deciding which normative dataset to use, the mode of data collection and age group have to be considered.

Sannes TS, Yusufov M, Amonoo HL, Broden EG, Burgers DE, Bain P, Pozo-Kaderman C, Miran DM, Smith TS, Braun IM, Pirl WF. Proxy ratings of psychological well-being in patients with primary brain tumors: A systematic review. Psychooncology 2023; 32:203-213. [PMID: 36371618 PMCID: PMC10373343 DOI: 10.1002/pon.6063] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/15/2022] [Revised: 10/14/2022] [Accepted: 10/31/2022] [Indexed: 11/15/2022]
Abstract
OBJECTIVE This systematic review examined the agreement of proxy ratings of depression and anxiety in neuro-oncology patients. METHODS Searches were conducted across 4 databases (MEDLINE, Embase, PsycINFO, CINAHL, and Web of Science) to identify studies that compared proxy ratings (non-health care providers) of anxiety and depression in patients with brain cancer. Methodological quality and potential risk of bias were evaluated using the Joanna Briggs Institute Critical Appraisal Checklist. RESULTS Out of the 936 studies that were screened for inclusion, 6 were included for review. The findings were mixed in terms of whether patient and proxy ratings were accurate (e.g., deemed equivalent), with many of the selected studies suggesting moderate level of agreement for several of the selected studies and, when both depression and anxiety were included, depression ratings from proxy raters were more accurate than for anxiety. We identified important limitations across the selected articles, such as low sample size, clarity on defining proxy raters and the different instructions that proxy raters are given when asked to assess patients' mood symptoms. CONCLUSIONS Our findings suggest that proxy ratings of depression and anxiety should be interpreted with caution. While there is some agreement in proxy and patients with brain cancer ratings of depression and anxiety (greater agreement for depression), future work should recruit larger samples, while also remaining mindful of defining proxy raters and the instructions given in collecting these ratings.

Abstract
The European Academy of Dermatology and Venereology (EADV) Task Forces (TFs) on Quality of Life (QoL) and Patient Oriented Outcomes, Melanoma and Non-Melanoma Skin Cancer (NMSC) present a review of the literature and position statement on health-related (HR) QoL assessment in skin cancer patients. A literature search was carried out to identify publications since 1980 that included information about the impact of SC on QoL. Generic, dermatology-specific, cancer-specific, SC-specific, facial SC-specific, NMSC-specific, basal cell carcinoma-specific and melanoma-specific QoL questionnaires have been used to assess HRQoL in SC patients. HRQoL was assessed in the context of creation and validation of the HRQoL instruments, clinical trials, comparison of QoL in SC and other cancers, other diseases or controls, HRQoL assessment after treatment, comorbidities, behaviour modification, predictors of QoL and survival, supportive care needs, coping strategies and fear of cancer recurrence. The most widely used instruments for HRQoL assessment in SC patients are the European Organisation for Research and Treatment of Cancer Core Questionnaire (EORTC QLQ-C30), the Functional Assessment of Cancer Therapy-Melanoma (FACT-M), Skin Cancer Index (SCI), Short Form 36 Item Health Survey (SF-36) and the Dermatology Life Quality Index (DLQI). The TFs recommend the use of the cancer-specific EORTC QLQ-C30, especially in late stages of disease, and the melanoma-specific FACT-M and SC-specific SCI questionnaires. These instruments have been well validated and used in several studies. Other HRQoL instruments, also with good basic validation, are not currently recommended because the experience of their use is too limited. Dermatology-specific HRQoL instruments can be used to assess the impact of skin-related problems in SC. The TFs encourage further studies to validate HRQoL instruments for use in different stages of SC, in order to allow more detailed practical recommendations on HRQoL assessment in SC.

Abstract
PURPOSE The health-related quality of life (HRQoL) outcomes after comprehensive surgical staging including infrarenal paraaortic lymphadenectomy in women with high-risk endometrial cancer (EC) are unknown. Our aim was to investigate the long-term HRQoL between robot-assisted laparoscopic surgery (RALS) and laparotomy (LT). PATIENTS AND METHODS A total of 120 women with high-risk stage I-II EC were randomised to RALS or LT for hysterectomy, bilateral salpingoophorectomy, pelvic and infrarenal paraaortic lymphadenectomy in the previously reported Robot-Assisted Surgery for High-Risk Endometrial Cancer trial. The HRQoL was measured with the European Organisation for Research and Treatment of Cancer Quality of Life Questionnaire Core 30 (EORTC-QLQ-30) and its supplementary questionnaire module for endometrial cancer (QLQ-EN24) questionnaire. Women were assessed before and 12 months after surgery. In addition, the EuroQol Eq5D non-disease specific questionnaire was used for descriptive analysis. RESULTS There was no difference in the functional scales (including global health status) in the intention to treat analysis, though LT conferred a small clinically important difference (CID) over RALS in 'cognitive functioning' albeit not statistically significant -6 (95% CI-14 to 0, p = .06). LT conferred a significantly better outcome for the 'nausea and vomiting' item though it did not reach a CID, 4 (95% CI 1 to 7, p = .01). In the EORTC-QLQ/QLQ-EN24, no significant differences were observed. Eq5D-3L questionnaire demonstrated a higher proportion of women reporting any extent of mobility impairment 12 months after surgery in the LT arm (p = .03). CONCLUSION Overall, laparotomy and robot-assisted surgery conferred similar HRQoL 12 months after comprehensive staging for high-risk EC.

Abstract
PURPOSE In surveys and in research, proxies such as family members may be used to assess patient health-related quality of life. The aim of this research is to help cancer researchers select a validated health-related quality of life tool if they anticipate using proxy-reported data. METHODS Systematic review and methodological appraisal of studies examining the concordance of paired adult cancer patient and proxy responses for multidimensional, validated HRQOL tools. We searched PubMed, CINAHL, PsycINFO and perused bibliographies of reviewed papers. We reviewed concordance assessment methods, results, and associated factors for each validated tool. RESULTS A total of 32 papers reporting on 29 study populations were included. Most papers were cross-sectional (N = 20) and used disease-specific tools (N = 19), primarily the FACT and EORTC. Patient and proxy mean scores were similar on average for tools and scales, with most mean differences <10 points but large standard deviations. Average ICCs for the FACT and EORTC ranged from 0.35 to 0.62, depending on the scale. Few papers (N = 15) evaluated factors associated with concordance, and results and measurement approaches were inconsistent. The EORTC was the most commonly evaluated disease-specific tool (N = 5 papers). For generic tools, both concordance and associated factor information was most commonly available for the COOP/WONCA (N = 3 papers). The MQOL was the most frequently evaluated end-of-life tool (N = 3 papers). CONCLUSIONS Proxy and patient scores are similar on average, but there is large, clinically important residual variability. The evidence base is strongest for the EORTC (disease-specific tools), COOP/WONCA (generic tools), and MQOL (end-of-life-specific tools).

Abstract
BACKGROUND New advanced melanoma therapies are associated with improved survival; however, quality of survivorship, particularly psychosocial outcomes, for patients overall and those treated with newer therapies is unclear. OBJECTIVE Synthesize qualitative and quantitative evidence about psychosocial outcomes for advanced (stage III/IV) melanoma patients. METHODS Five databases were searched (01/01/1980 to 31/01/2016). Inclusion criteria were as follows: advanced melanoma patients or sub-group analysis; assessed psychosocial outcomes; and English language. RESULTS Fifty-two studies met review criteria (4 qualitative, 48 quantitative). Trials comprise mostly medical not psychosocial interventions, with psychosocial outcomes assessed within broader quality of life measures. Patients receiving chemotherapy or IFN-alpha showed decreased emotional and social function and increased distress. Five trials of newer therapies appeared to show improvements in emotional and social function. Descriptive studies suggest that patients with advanced, versus localized disease, had decreased emotional and social function and increased distress. Contributors to distress were largely unexplored, and no clear framework described coping/adjustment trajectories. Patients with advanced versus localized disease had more supportive care needs, particularly amount, quality, and timing of melanoma-related information, communication with and emotional support from clinicians. Limitations included: lack of theoretical underpinnings guiding study design; inconsistent measurement approaches; small sample sizes; non-representative sampling; and cross-sectional design. CONCLUSIONS Quality trial evidence is needed to clarify the impact of treatment innovations for advanced melanoma on patients' psychosocial well-being. Survivorship research and subsequent translation of that knowledge into programs and services currently lags behind gains in the medical treatment of advanced melanoma, a troubling circumstance that requires immediate and focused attention.

A Cross-Sectional Investigation of Fatigue, Mucositis, Hand-Foot Syndrome and Dysgeusia in Advanced Renal Cell Carcinoma Treatment: Final Results From the FAMOUS Study. Clin Genitourin Cancer 2015; 14:63-8. [PMID: 26520429 DOI: 10.1016/j.clgc.2015.09.004] [Citation(s) in RCA: 4] [Impact Index Per Article: 0.4] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/23/2015] [Revised: 08/21/2015] [Accepted: 09/11/2015] [Indexed: 11/25/2022]
Abstract
UNLABELLED Treatment of metastatic renal cell carcinoma can be associated with adverse symptoms. The perception of fatigue, mucositis, hand-foot syndrome, and dysgeusia, and quality of life (QOL) was assessed in 63 oncologists and their patients receiving first-line treatment. Physicians underestimated the severity of the symptoms and the severity correlated with a lower QOL. A consistent assessment of symptoms in routine practice might improve QOL, adherence to treatment, and outcome. BACKGROUND The management of symptoms associated with treatment of metastatic renal cell carcinoma (mRCC) is crucial to ensure treatment adherence and outcome. The perception of symptoms can vary between the treating physician and patient, leading to assumptions and subsequent changes in treatment, potentially affecting treatment effectiveness. The aim of the present cross-sectional study was to evaluate the perception of the common symptoms of fatigue, mucositis, hand-foot syndrome, and dysgeusia in patients with mRCC receiving systemic therapies in routine practice. PATIENTS AND METHODS German patients receiving first-line systemic treatment for mRCC and their physicians were independently queried about the incidence and severity of fatigue, mucositis, hand-foot syndrome, and dysgeusia. Patients also completed the Functional Assessment of Cancer Therapy-General questionnaire to assess their quality of life (QOL). The effect of the 4 symptoms on QOL was analyzed using linear regression modeling. RESULTS A total of 63 matching questionnaires were completed by both physicians and patients with first-line treatment. The incidence and severity of symptoms differed between the patients and physicians. Patients rated the severity of symptoms significantly higher than did the physicians. A greater severity of symptoms correlated with a lower QOL. In multivariate regression analysis, fatigue adversely affected overall QOL. CONCLUSION Physicians underestimated the severity of common symptoms in patients with mRCC. The incorporation of patient-reported outcome measures into routine practice might increase awareness of patients' overall QOL and thereby potentially improve treatment adherence. A thorough evaluation of fatigue, its potential underlying causes, and active measures to manage fatigue could potentially improve patients' QOL.

Abstract
BACKGROUND Systematic symptom assessment is not routinely performed in pediatric oncology. The objectives of the current study were to characterize the symptoms of pediatric oncology outpatients and evaluate agreement between patient and proxy reports and the association between children's ratings and oncologists' treatment recommendations. METHODS Two versions of the pediatric Memorial Symptom Assessment Scale (pMSAS) were translated into Spanish. An age-appropriate and language-appropriate pMSAS was administered independently before visits to the oncologist to patients and family caregivers (caregivers) and after visits to consenting oncologists. Statistical analysis included Spearman correlation coefficients and weighted kappa values. RESULTS English and Spanish results were similar and were combined. A total of 60 children and their caregivers completed the pMSAS. The children had a median age of 10 years (range, 7-18 years); approximately 62% were male and 33% were Spanish-speaking. Fourteen oncologists completed the pMSAS for 25 patients. Nine patients (15%) had no symptoms and 38 patients (63%) reported ≥2 symptoms. The most common symptoms were fatigue (12 patients; 40%) and itch (9 patients; 30%) for the younger children and pain (15 patients; 50%) and lack of energy (13 patients; 45%) among the older children. Total and subscale score agreement varied by proxy type and subscale, ranging from fair to good for most comparisons. Agreement for individual symptoms between the patient and proxy ranged from a kappa of -0.30 (95% confidence interval, -0.43 to -0.01) to 0.91 (95% confidence interval, 0.75 to 1.00). Three of 51 symptomatic patients (6%) had treatment recommendations documented in the electronic health record. CONCLUSIONS Symptoms are common and cross several functional domains. Proxy and child reports are often not congruent, possibly explaining apparent undertreatment among this group of patients.

Abstract
PURPOSE Prostate cancer survivors (PCSs) may experience persistent symptoms following treatment. If PCSs and spouses differ in their perceptions of symptoms, that incongruence may cause mismanagement of symptoms and reduced relationship quality. The purpose of this study was to examine symptom incongruence and identify the PCS and spouse characteristics associated with symptom incongruence in older couples coping with prostate cancer. METHODS Participants in the study were older PCSs (>60 years) and their spouses (N=59 couples). Symptom incongruence was determined by comparing patient and spouse independent ratings of the severity of his cancer-related symptoms. Predictor variables included PCS age, time since diagnosis, PCS comorbidity, PCS and spouse depressive symptoms, and spouse caregiving strain. RESULTS PCS and spouse ratings of his symptom severity and the amount of incongruence over his symptoms varied significantly across couples. Overall, couples rated a moderate level of PCS symptom severity, but PCSs and their spouses significantly differed in their perceptions of PCS symptom severity with spouses rating severity higher (t=-2.66, df=51, p<0.01). PCS younger age and high spouse caregiver strain accounted for 29 % of incongruence in perceptions of PCS symptom severity. CONCLUSIONS This study is among the first to show that PCSs and spouses may perceive cancer-related persistent symptoms differently. Among this older sample, younger PCS age and spouse caregiver strain were associated with incongruence in symptoms perceptions in couples. These and other factors may inform future interventions aimed at preserving relationship quality in older couples who have experienced prostate cancer.

Abstract
BACKGROUND From March 1994 to March 1998, breast cancer patients (an estimated relapse risk with 70% or more within five years with standard therapy) were randomised to treatment with tailored fluorouracil, epirubicin, and cyclophosphamide (FEC) therapy or FEC followed by marrow-supported high dose therapy in the Scandinavian Breast Group 9401 study. The aim of the present paper was to investigate differences in toxicity and eight health-related quality of life (HRQoL) variables (physical functioning, role functioning, emotional functioning, social functioning, cognitive functioning, fatigue, nausea-vomiting, and global quality of life) between women in the six dose steps used in the tailored and granulocyte colony stimulating factor supported FEC-arm at the assessment point 16 weeks after random assignment to treatment. METHODS The European Organization and Treatment of Cancer Quality of Life Questionnaire EORTC QLQ-C30 were mailed to the patients. RESULTS A total of 157 (87%) in the tailored FEC-group responded to the questionnaire within the time frame 16 weeks after inclusion in the study. Overall, toxicity was low, reaching grade 1-2 also in the higher dose steps. There were no overall differences between the dose steps on any of the tested HRQoL variables. Patients at dose step 4 scored statistically significantly higher on physical functioning than patients at dose step 1 (p = 0.022) and compared to those at dose step 2 (p = 0.014). Patients at dose steps -2 and -1 (combined to one group) reported statistically significantly higher mean scores on cognitive functioning than patients at dose step 1 (p = 0.022). CONCLUSION Patients who received higher doses, based on the tailored dosing strategy, did not seem to have worse HRQoL than those who had lower doses.

Abstract
In a prospective randomised Scandinavian trial, patients with localised invasive cutaneous melanoma of the trunk or extremities with tumours more than 2 mm thick were randomly assigned to excision with narrow (2 cm) or wide (4 cm) margins after primary surgery. The aims of the present study were to find out if there were any differences in health-related quality of life (QoL) and emotional distress between patients in the two arms over time. Patients were assessed at four time points: before randomisation, and at 3, 9, and 15 months after inclusion, using the EORTC QLQ-C30, the Hospital Anxiety and Depression Scale and the Impact of Event Scale. A study-specific questionnaire was used to assess patient-reported problems related to the scar. A total of 144 patients were included; 70 randomised to narrow excision and 74 to wide excision margins. The response rate was >85% at all assessment points. No differences between the two arms were found for health-related QoL or emotional distress. Emotional functioning, insomnia, anxiety, intrusion, and avoidance improved over time (p <or= 0.0001). Thirty patients (32%) reported problems with the scar but there was no difference between the two arms. No differences in health-related QoL or emotional distress were found between the two arms, indicating that resection margins have limited impact on these variables.

Abstract
OBJECTIVE This study examined the extent and the nature of agreement on health-related quality of life (QOL) assessments between terminally ill cancer patients and their primary family caregivers in Japan, using a multidimensional QOL instrument including psychosocial and spiritual domains. METHODS The Functional Assessment of Chronic Illness Therapy-Spiritual well-being questionnaire was used to assess patients' QOL. Study subjects were inpatients of a palliative care unit (PCU), outpatients who applied for admission to the PCU, and their primary family caregivers. RESULTS QOL ratings were obtained from 102 of 197 eligible patient-caregiver dyads. A moderate level of patient-family concordance on patients' overall QOL as well as families' underestimation of patients' QOL were observed. Families reported on observable domains of patients' QOL more reliably and assessed subjective aspects, such as psychospiritual concerns less accurately. Families tended to underrate the patients' social aspect of QOL, whereas most patients gave the highest rating on support from their families. The spiritual domain, particularly regarding faith, showed the least agreement. The size of the systematic bias between patient and family assessments on the patients' QOL was moderate (>0.50). CONCLUSIONS Families' limited ability to assess psychosocial and spiritual aspects of patients' QOL may suggest the need for better approaches or measures to assess these aspects of a patient's life. The systematic bias was larger than in earlier studies. Further investigation is needed to identify factors affecting patient-family discord on QOL assessments to guide effective interventions to enhance patient-caregiver agreement.

Abstract
The objective of this study was to review the literature on depression in palliative cancer care in order to identify which assessment methods and classification systems have been used in studies of depression. Extensive electronic database searches in PubMed, CancerLit, CINAHL, PsychINFO, EMBASE and AgeLine as well as hand search were carried out. In the 202 included papers, 106 different assessment methods were used. Sixty-five of these were only used once. All together, the Hospital Anxiety and Depression Scale (HADS) was the most commonly used assessment method. However, there were regional differences and while the HADS dominated in Europe it was quite seldom used in Canada or in the USA. Few prevalence and intervention studies used assessment methods with an explicit reference to a diagnostic system. There were in total few case definitions of depression. Among these, the classifications were in general based on cut-off scores (77%) and not according to diagnostic systems. The full range of the DSM-IV diagnostic criteria was seldom assessed, i.e. less than one-third of the assessments in the review took into account the duration of symptoms and 18% assessed consequences and impact upon patient functioning. A diversity of assessment methods had been used. Few studies classified depression by referring to a diagnostic system or by using cut-off scores. Evidently, there is a need for a consensus on how to assess and conceptualize depression and related conditions in palliative care.

Abstract
OBJECTIVES To assess the ability of partners and clinicians to make proxy judgements on behalf of patients with prostate cancer relating to selection of life priorities and quality of life (QoL). DESIGN 47 consecutive patients with histologically proven adenocarcinoma, and their partners, were recruited. The partners were asked to assess, by proxy, the QoL of the patient by completion of a series of interview-led questionnaires assessing global QoL (SEIQoL-DW), health-related QoL (FACT-P) and overall QoL (visual analogue score [VAS]). The patients' clinicians were asked to complete the SEIQoL-DW and VAS by proxy as soon as possible after a consultation with the patient. SETTING Patients with histologically proven adenocarcinoma, their partners and their clinicians. MAIN OUTCOME MEASURES Proxy scores for SEIQoL-DW, FACT-P and VAS, as provided by partners and clinicians. RESULTS 25 partners made a proxy assessment of the patients. The results showed that partners were able to select similar QoL cues to those of the patients (Spearman-Rank correlation 0.89). Comparison of the QoL scores obtained from patients and partners in proxy using the questionnaires showed no statistically significant difference (paired t-test). Urologists were poor predictors of areas of life (cues) that were important to their patients. The doctors overemphasized the importance of survival, postoperative complications, urinary symptoms, sexual ability, activities of daily living and finance, but underestimated the importance of wife, family, home and religion. Comparison of the QoL scores obtained from patients and urologists by proxy showed a significantly lower score when assessed by urologists using the SEIQoL-DW questionnaire. CONCLUSIONS Partners are able to accurately assess, by proxy, the areas of life that are of importance to patients. Clinicians, however, who are charged with making decisions on behalf of patients, are very poor judges of their patients' life priorities and QoL. This illustrates that conventional views held by most doctors regarding the priorities patients set themselves when planning treatment should be called into question and consequently suggests that the way in which doctors and patients arrive at treatment decisions must be reviewed.

Abstract
OBJECTIVE To examine whether a caregiver can provide reliable proxy quality of life (QOL) ratings of their adult significant other with a newly diagnosed high-grade glioma. METHODS This prospective QOL study was a companion protocol for 3 phase II high-grade glioma protocols. At study entry, 2 months, and 4 months after enrollment, 5 self-administered forms were completed by 197 patients and their caregivers to assess QOL. RESULTS Caregiver ratings of QOL were available, respectively, for 92%, 93%, and 88% of baseline, 1st, and 2nd subsequent follow-up evaluations of patients who had completed their QOL assessments. There was a strong relationship between patient and caregiver QOL scores (Spearman and intraclass correlation coefficients greater than 0.5 for 87% and 80% of the measurements, respectively); however, for some measures (eg, the profiles of mood states short form) there was better agreement between patient and caregiver scores when the QOL scores were higher. There was good agreement between patient and proxy ratings independent of the cognitive function of the patient, except for the profiles of mood states short form with better correlation between patients and caregivers for those patients without cognitive impairment. CONCLUSIONS In this multi-institutional prospective study there is a strong correlation between high-grade glioma patient and caregiver QOL scores, although for some measures this correlation is stronger for those patients without cognitive impairment. To improve the acquisition and the accuracy of assessing QOL status in high-grade glioma patients, proxy ratings from caregivers should also be obtained in conjunction with the patient, and consideration be given to substituting proxy ratings when a patient's self-report is absent.

Abstract
OBJECTIVE Metastatic melanoma (MM), a major concern for health-care providers, is increasing. We systematically reviewed published articles describing the impact of interventions (drugs and screening) on quality of life (QoL) in patients with MM, and articles that measured QoL in MM. METHODS We searched secondary databases including MEDLINE, Embase, CINAHL, Cochrane, and DARE from inception to 2006 using MESH terms "melanoma" and "metastases." Economic articles were subject to established quality assessment procedures. RESULTS We found 13 QoL and five economic studies (three cost-effectiveness, two cost-utility; average quality = 83% +/- 7%). No strong evidence was found in this review for cost-effectiveness of interferons in Canada (incremental cost-effectiveness ratio [ICER] = $55,090/quality-adjusted life-year) or temozolomide in the United States (ICER = $36,990/Life-year gained based on nonsignificant efficacy differences). Melanoma screening was not cost-effective in the United States ($150,000-931,000/life-saved) or Germany (no survival benefit). From the 13 QoL studies,eight measured baseline QoL; six studied the same population, generating similar results using different approaches/outcomes. Tools used included GLQ-8, QLQ-C30, QLQ-36, QWB-SA, and SF-36. Baseline scores QoL scores ranged from 0.60 to 0.69. Another five studies (N = 959 patients) were randomized trials analyzing QoL in patients treated with dacarbazine alone, dacarbazine +/- interferon, dacarbazine + fotemustine, interleukin +/- histamine, and temozolomide. Little difference was found in QoL scores between drugs or between baseline and end point. CONCLUSIONS Cost-effectiveness has not been widely demonstrated for treatment of MM. Only two studies with unimpressive results exist for treatments. Screening was not cost-effective in the United States or Germany. Generally, no significant improvements in QoL were found for any alternative for treating MM. A need exists for effective treatments that improve duration and QoL.

Abstract
OBJECTIVES To develop a new patient-based outcome measure in plastic surgery for head/neck skin lesions for use in audit, clinical trials and effectiveness studies. DESIGN AND SUBJECTS Questionnaire development and validation study. Qualitative methods, including interviews with 27 patients, were carried out to develop a preliminary version of the questionnaire. The questionnaire was then field tested by postal survey of 141 pre- and 250 post-surgery patients to produce a shortened (item-reduced) questionnaire and to evaluate acceptability, reliability, validity and responsiveness. A second field test was carried out by postal survey in an independent sample of 67 pre-surgery patients to further evaluate the reliability and validity of the questionnaire. MAIN OUTCOME MEASURES Psychometric properties of acceptability, reliability, validity, and responsiveness were assessed. RESULTS We developed a new measure, the Patient Outcomes of Surgery-Head/Neck (POS-Head/Neck), which includes a six- and nine-item pre- and post-surgery questionnaire, respectively. Results confirmed the acceptability (missing data <10%, evenly distributed endorsement frequencies), reliability (Cronbach alphas >0.76, item-total correlations >0.22), validity (scale inter-correlations r=0.50, scaling assumptions, correlations with age and sex < -0.25) and responsiveness (effect size=0.63) of the questionnaire. CONCLUSIONS The POS-Head/Neck is a new surgical outcome measure that can be used to evaluate outcomes in malignant and benign head/neck skin lesions before and after surgery is acceptable to patients and satisfies rigorous scientific criteria.

Abstract
OBJECTIVES This study explores how well staff and family proxies' reports on selected quality-of-life (QOL) domains (comfort, dignity, functional competence, privacy, meaningful activity, food enjoyment, relationships, security, and autonomy) correspond to residents' own reports. METHODS We compared QOL domain scores for nursing home residents and 1,326 staff proxies and 989 family proxies at the individual and facility level using means, Pearson correlation statistics, and intraclass correlations. Regression models adjusted for residents' age, gender, length of stay, ability to perform activities of daily living, and cognition. RESULTS For each domain in more than half the cases, proxy means were within 1 SD of the resident means. Resident and family proxy individual reports for selected domains were correlated at 0.14 to 0.46 (all p <.000). Resident and staff proxy individual reports were correlated at 0.13 to 0.37 (all p <.000). Correlation of mean levels by facility for staff proxies was 0.26 to 0.64 (generally p <.05) and for family proxies 0.13 to 0.61 (p <.01 except for one domain). DISCUSSION Although staff and family proxy domain scores are significantly correlated with resident scores, the level of correlation suggests they cannot simply be substituted for resident reports of QOL. Determining how proxy reports can be used for residents who cannot be interviewed at all remains an unresolved challenge.

Abstract
The present study prospectively assessed consistency of ratings of health-related quality of life between patients with hepatocellular carcinoma and two types of proxy raters, family caregivers and oncologist care providers. Patients and proxies completed the Functional Assessment of Cancer Therapy-Hepatobiliary (FACT-Hep) at baseline prior to treatment (82 patients plus proxies), at 3-months (32 patients plus proxies), and 6-months follow up (16 patients plus proxies) after diagnosis. Patient and proxy demographic data and patient medical data were also collected. At baseline, significant intra-class correlations (ICC) were found for patient--caregiver ratings of physical, social/family, and functional well-being, additional concerns (symptoms, side effects), and overall health related quality of life (HRQL); for patient--care provider ratings of physical well-being; and for caregiver--care provider ratings of physical and emotional well-being. At 3-months follow-up, the most significant number of ICCs were recorded across all three rater pairs. Significant consistencies were found for overall HRQL, and all subscale scores except for social and family well-being. The fewest significant ICCs were found at the 6-month follow-up, and were for patient--caregiver ratings of physical and functional well-being, and additional concerns; and for caregiver--care provider ratings on overall HRQL. These results suggest that family caregivers are adequate proxies of patient physical and functional well-being and additional concerns throughout the patient's illness, more so than oncologist care providers. Further research is warranted with larger samples.

Abstract
Purpose: To compare, in high-risk breast cancer patients, the effects on health-related quality of life (HRQoL) of two adjuvant treatments. Treatments were compared at eight points during the first year after random assignment to treatment with tailored fluorouracil, epirubicin, and cyclophosphamide (FEC) therapy for nine courses versus induction FEC therapy for three courses followed by high-dose chemotherapy with cyclophosphamide, thiotepa, and carboplatin (CTCb) supported by peripheral-blood stem cells. Patients and Methods: From March 1994 to March 1998, 525 breast cancer patients (estimated relapse risk > 70% within 5 years with standard therapy) were included in the Scandinavian Breast Group 9401 study. HRQoL evaluation, using the European Organization for Research and Treatment of Cancer Quality of Life Questionnaire (EORTC QLQ)-C30 and EORTC Breast Cancer Module–23, included 408 of 446 eligible patients in Finland, Norway, and Sweden. Results: Eighty-four percent to 95% of the patients completed questionnaires at eight points of assessment. Nostatistically significant overall differences were found between the tailored FEC group and the CTCb group for any of the HRQoL variables. Statistically significant differences over time were found for all HRQoL variables. HRQoL in the CTCb group demonstrated a steeper decrease, but a faster recovery than in the tailored FEC group. Emotional functioning improved with increased time from randomization. Higher levels of problems in body image and arm symptoms were reported in the tailored FEC group compared with the CTCb group. Sexual functioning and satisfaction were impaired during the study period. Conclusion: Both treatments had a negative influence on HRQoL during the treatment period. Despite the aggressive therapies, the patient’s HRQoL returned to levels found at inclusion on most variables.

Abstract
Quality of life (QOL) has recently become one of the most important focuses in oncology nursing practice and research. The aims of this study were to evaluate the QOL in Chinese cancer patients under chemotherapy and to explore the discrepancy between patients' and nurses' assessments of the patients' conditions. The study participants included gestational trophoblastic disease patients (n = 68), ovarian cancer patients (n = 105), patients with other gynaecological cancer (n = 18), and their attending nurses (n = 25) at hospitals affiliated with universities in Beijing. The high level of some symptom subscales/items in patients suggested that innovative and more effective interventions should be developed and utilised in nursing practice. Patients with metastasis reported lower levels of QOL than those without metastasis. The nurses in this study tended to estimate the patients' QOL inaccurately, except for a few objective aspects. The results of this study can help nurses in planning interventions to enhance the QOL of patients with gynaecological cancer undergoing chemotherapy. The nurses need to be trained to become more sensitive and competent in assessing patients' subjective information.

Abstract
A major challenge in research into care at the end of life is the difficulty of obtaining the views and experiences of representative samples of patients. Studies relying on patients' accounts prior to death are potentially biased, as they only represent that proportion of patients with an identifiable terminal illness, who are relatively well and therefore able to participate, and who are willing to take part. An alternative approach that overcomes many of these problems is the retrospective or 'after death' approach. Here, observations are gathered from proxies, usually the patient's next of kin, following the patient's death. However, questions have been raised about the validity of proxies' responses. This paper provides a comprehensive review of studies that have compared patient and proxy views. The evidence suggests that proxies can reliably report on the quality of services, and on observable symptoms. Agreement is poorest for subjective aspects of the patient's experience, such as pain, anxiety and depression. The findings are discussed in relation to literature drawn from survey methodology, psychology, health and palliative care. In addition to this, factors likely to affect levels of agreement are identified. Amongst these are factors associated with the patient and proxy, the measures used to assess palliative care and the quality of the research evaluating the validity of proxies' reports. As proxies are a vital source of information, and for some patients the only source, the paper highlights the need for further research to improve the validity of proxies' reports.

Abstract
One of the main goals of end-of-life care is to achieve the best quality of life (QOL) for patients and their families. Quality of life, therefore, represents a significant outcome indicator to evaluate end-of-life care interventions. However, nonresponse bias and nonrandom missing data in QOL research at the end-of-life limits the generalizability and threatens the internal validity of the study findings. The use of family proxy of patients' QOL has been suggested as a solution. Demonstration of satisfactory levels of agreement between proxies and patients is warranted before family caregivers' or other proxies' assessments can be employed when patients cannot provide their own information. Contrary to the conclusion made by Sprangers and Aaronson [The Role of Health Care Providers and Significant Others in Evaluating the Quality of Life of Patients with Chronic Disease: A Review. J. Clin. Epidemiol. 1992, 45, 743-760], it is suggested from this review of literature that terminal cancer patients and their family caregivers agreed at least moderately well on the patients' QOL. The bias introduced by the use of family informants is generally of a modest magnitude. When discrepancies existed, without exception, family caregivers held a more negative view of patients' QOL than did patients. When using family proxies, this is important to remember. The degree of agreement between terminal cancer patients' and their family caregivers' assessments varies as a function of the dimensions of QOL being measured and the patient's health status. However, the accuracy of family caregivers' assessments can be improved by assessing both patients and family caregivers concurrently over time. Several suggestions for future research are provided to better understand the influencing factors of agreement between patients and family assessments and to enhance the quality of statistical analyses on this topic.

Abstract
Health-related quality of life (HRQL) studies sometimes rely, in part, on proxy information obtained from patients' significant others (spouse or close companion) or health care providers. This review: (1) provides a quantitative analysis of the results that have been reported in recent studies assessing the level of agreement between patient and proxy HRQL ratings, and (2) addresses a number of key methodological issues surrounding the use of proxy raters in HRQL research. This review concentrates on 23 studies, published between 1991-2000, that describe patient-proxy agreement for a number of well-known multidimensional HRQL instruments. In general, moderate to high levels of patient-proxy agreement were reported. Lower levels of agreement were found predominantly in studies employing a small sample size (approximately 50 patient-proxy pairs or less). In larger studies comparing patients and their significant others, median correlations were between 0.60-0.70 for physical HRQL domains and about 0.50 for psychosocial domains. Mixed results were reported in studies comparing patients and their health care providers, but most of these studies employed a relatively small sample size. Proxy raters tended to report more HRQL problems than patients themselves, but the magnitude of observed differences was modest (median standardized differences of about 0.20). Based on the current evidence, we conclude that judgements made by significant others and health care providers about several aspects of patients' HRQL are reasonably accurate. Substantial discrepancies between patient and proxy ratings occur in a minority of cases. We recommend that future studies focus on: (a) the reliability and validity of proxy ratings according to common psychometric methods, and (b) the balance between information bias due to proxy ratings and potential selection bias due to exclusion of important patient subgroups from HRQL studies.

Abstract
Next of kin (NOK) play an integral role in fostering optimal quality of life in symptomatic patients who are coping with cancer in the home setting. Often when patients in advanced stages of cancer are no longer able to meaningfully communicate their illness and symptom needs, healthcare professionals turn to NOK to provide sound estimates of patients' symptom experiences. This overview is based on 37 research studies written between 1987 and 2002 and updates an earlier overview of 13 studies on patient-NOK response comparability. The purpose is to, first, promote a better comprehension of methodologies and statistical techniques commonly employed to measure patterns of response comparability (or levels of agreement) between patient self-reports and NOK estimates on patient quality-of-life experiences of physical or symptom and emotional or psychological well-being. The second aim is to identify conditions where NOK may pose as reasonably accurate judges of patients' health-related quality of life, particularly symptom experiences arising from various diagnoses, including cancer. Third, subsequent to identifying the gaps in current research knowledge and limitations in study designs, recommendations for statistical and methodological techniques are outlined.

Abstract
The aim of this study was to evaluate interrater and intermodality agreement in assessing health status using the Health Utilities Index. A random sample from a Dutch cohort of 14-year-old Very Low Birth Weight children and their parents were invited to participate in a face-to-face (n = 150) or telephone (n = 150) interview. All 300 participants were also sent a questionnaire by mail. Response rate was 68%. Interrater and intermodality agreement were high for the physical HUI3 attributes and poor for the psychological attributes. Children and parents reported more dysfunction in the psychological attributes when interviewed than when completing the mailed questionnaire. High agreement on the physical attributes may have resulted from the fact that hardly any dysfunction was reported in these attributes, and poor agreement in the psychological attributes may have been a result of the fact that in these attributes much more dysfunction was reported. In measuring children's health status using the HUI3, the results and their interpretation vary with the source of information and the modality of administration. For maximum comparability between studies, written self-report questionnaires seem the preferred option.

Abstract
PURPOSE We examined the extent of agreement in health related quality of life ratings provided by patients with metastatic prostate cancer and their spouses. This agreement is important for determining the feasibility of using spouses as potential proxy raters in quality of life studies in this patient population. MATERIALS AND METHODS The study sample consisted of 72 pairs of patients with metastatic prostate cancer in remission or progression and their spouses. Patients and spouses independently completed the European Organization for Research and Treatment of Cancer Quality of Life Questionnaire-C30 and a prostate cancer specific questionnaire module. Together the 2 questionnaires assess a wide range of symptoms and functional limitations for a total of 21 quality of life outcomes. RESULTS For 5 of the 21 patient-proxy comparisons we noted systematic differences in the mean score with spouses rating more impairment in patients than patients indicated. Most patient-proxy correlations were 0.40 to 0.75, indicating moderate to good agreement in patient and spouse ratings. A low patient-proxy correlation of less than 0.40 was noted only for the 2 measures of sexual function. CONCLUSIONS Our findings suggest that the spouses of men with metastatic prostate cancer evaluate with a fair degree of accuracy how patients experience physical and psychosocial functioning, symptoms and overall quality of life. However, caution should be exercised when relying on proxy raters for assessing sexual functioning and satisfaction.

Abstract
The aim of this study was to evaluate the agreement between children and proxies as well as the agreement between methods of administration in assessing Health-Related Quality of Life (HRQoL) using the TNO AZL Children's Quality Of Life (TACQOL) questionnaire. A random sample from a Dutch cohort of 14-year-old very low birth weight children and their parents were invited to participate in a face-to-face (n = 150) or telephone interview (n = 150). Participants were also sent a questionnaire by mail. The response rate was 83%. Inter-rater and intermethod agreement were generally good in observable HRQoL domains, and moderate in less readily observable, and possibly less stable, domains such as moods, pain and physical symptoms, and social functioning. In measuring children's HRQoL using the TACQOL, the results and their interpretation are dependent on the source of information and the method of administration.

Abstract
PURPOSE The purpose of this study was to examine the reliability of symptom assessments in advanced cancer patients under various conditions, including multiple raters (patients, nurses, and family caregivers), occasions, and symptoms. PATIENTS AND METHODS The study sample consisted of 32 advanced cancer patients admitted to a tertiary palliative care unit. Symptom assessments were completed for each patient on two separate occasions, approximately 24 hours apart. On each occasion, the patient, the primary care nurse, and a primary family caregiver independently completed an assessment using the Edmonton Symptom Assessment System (ESAS). The ESAS is a nine-item visual analogue scale for assessing symptoms in palliative patients. The reliability of the assessments (r) was examined using generalizability theory. RESULTS Three important findings emerged from this analysis. First, the analysis of individual symptom ratings provided a more meaningful representation of the symptom experience than total symptom distress ratings. Secondly, patients, nurses, and caregivers varied in their ratings across different patients, as well as in their ratings of shortness of breath, which may have been a result of individual rater variability. Finally, reliability estimates (r), based on a single rater and one occasion, were less than.70 for all symptoms, except appetite. These estimates improved substantially (r >/=.70) for all symptoms except anxiety and shortness of breath, using three raters on a single occasion or two raters across two occasions. CONCLUSION The findings from this study reinforce the need for the development of an integrated symptom assessment approach that combines patient and proxy assessments. Further research is needed to explore individual differences among raters.

Abstract
This study examined the usefulness of caregiver ratings of cancer patients' quality of life (QOL), an issue of relevance to both adequate patient care and to the possible use of proxy QOL raters in clinical studies. We compared QOL ratings of 90 cancer patients receiving inpatient chemotherapy with those provided by their significant others (most often the spouse), physicians and nurses. During patients' scheduled appointment for receiving chemotherapy on a clinical ward, all raters completed independently the Dartmouth COOP Functional Health Assessment charts/WONCA, an instrument developed by a cooperative group of primary care physicians to briefly assess a core set of seven QOL domains (physical fitness, feelings, daily and social activities, overall health, pain and quality of life) by single items with five response options. With few exceptions, mean scores of the proxy raters were equivalent or similar to those of the patients. Most patient-proxy correlations varied between 0.40 and 0.60, indicating a moderate level of agreement at the individual level. Of all comparisons made, 41% were in exact agreement and 43% agreed within one response category, leaving 17% more profound patient-proxy discrepancies. Disagreement was not dependent on the type of proxy rater, or on raters' background characteristics, but was influenced by the QOL dimension under consideration and the clinical status of the patient. Better patient-proxy agreement was observed for more concrete questions (daily activities, pain) and for patients with either a very good (ECOG 0) or poor (ECOG 3) performance status. The results indicate that both significant others and health care providers can be useful sources of information about cancer patients' QOL.

Abstract
OBJECTIVE Baseline patient functional status as assessed by providers is correlated with mortality after intensive care unit (ICU) admission. We wanted to see if patient self-perception of health status before admission to an ICU correlated with functional outcome. DESIGN Prospective survey on a convenience sample. SETTING Single urban university-affiliated Veterans Affairs Medial Center. PATIENTS One hundred ninety-nine patients in surgical and medical/coronary ICUs. INTERVENTIONS None. MEASUREMENTS Patient-assessed baseline health status was monitored with the Medical Outcome Survey Short-Form 36 (SF-36), consisting of 36 questions that evaluate eight health status concepts. In addition, baseline functional status (Zubrod scale) was determined and severity of illness (Acute Physiology and Chronic Health Evaluation [APACHE] II) data were collected. Zubrod functional status, which includes mortality, was determined 6 wks and 6 months after ICU admission, and correlation coefficients were calculated. MAIN RESULTS We found it feasible to collect SF-36 health status data on a 9% sample in this setting. Less than 1% of responses were completed by proxy. The SF-36 data were internally consistent, and several of its scales including general health perception and physical functioning correlated with patient Zubrod functional status (r2 = .08, p < .001; r2 = .14, p < .001) at 6 wks as did vitality (r2 = .04, p < .01), social function (r2 = .03, p < .05), and physical role function (r2 = .02, p = .053), although to a lesser extent. Similar correlations were also found with 6-month functional status. CONCLUSIONS We conclude that use of the SF-36 is time efficient in an ICU setting and correlates with 6-wk and 6-month functional outcome. It correlates as well with functional outcome as either the baseline Zubrod functional status or the APACHE II severity of illness measurement. The five-question general health evaluation portion correlated almost as well with outcome as the more extensive 36-item questionnaire. Use of the SF-36 may define patient populations for comparison across hospitals. It may also target individuals with needs for additional posthospitalization care, including rehabilitation services or nursing home placement.

Abstract
The pharmaceutical industry, the medical device industry, and national regulatory agencies such as the United States Food and Drug Administration (FDA) are faced with a number of difficult issues related to the development and evaluation of health-related quality of life (HRQL) claims for product labeling and promotion. This paper outlines some of the unique challenges of HRQL research and makes recommendations for assuring that claims are based on the results of rigorous studies designed and conducted according to accepted scientific principles and practices. Standards of evidence for HRQL are discussed in terms of research design and methodology, instrumentation, statistical analysis, and interpretation. Examples are provided to highlight important points. The paper concludes with a brief discussion of future trends in HRQL outcomes evaluation.

Abstract
The aim of this study was to examine whether significant others can provide useful proxy information on the health-related quality of life (QL) of cancer patients. We examined the level and pattern of agreement between patient and proxy ratings of the EORTC QLQ-C30, the reliability and validity of both types of information, and the influence of several factors on the extent of agreement. QL ratings were obtained for 307 and 224 patient-proxy pairs (at baseline and follow-up, respectively). Agreement was moderate to good (ICC = 0.42 to 0.79). Multitrait-multimethod analysis showed good convergence and discrimination of specific QL domains. Comparison of mean scores revealed a small but systematic bias between patient and proxy ratings. The maximum level of disagreement was found at intermediate levels of QL, with smaller discrepancies noted for patients with either a relatively poor or good QL. Both patient and proxy QL ratings were reliable and responsive to changes over time. Several characteristics of the patients and their significant others were found to be associated with the level of agreement, but explained less than 15% of the variance in patient-proxy differences. In conclusion, the present findings lend support to the viability of employing significant others as proxy respondents of cancer patients' quality of life where this is necessary.

Abstract
Quality of life (QL) assessment is now regarded as desirable, if not mandatory, by agencies supporting cancer clinical trials around the world, yet doubts persist about the relevance of QL data to clinical practice. A plethora of QL measures is available but the quality of published work remains suboptimal. The appropriate choice of instrument is essential if outcome measures are to be valid and clinically meaningful. This paper reviews the considerations which should determine the choice of QL questionnaire and, taking the specific example of the EORTC approach, aims to provide users with an update on the current state of the art in the development of cancer-specific QL questionnaires.
