Stability of health-related quality of life in the Norwegian general population and impact of chronic morbidity in individuals with and without a cancer diagnosis

Image guided radiotherapy in curative treatment for prostate cancer. 5-year results from a randomized controlled trial (RIC-trial)

BACKGROUND

Between 2012 and 2015 we conducted a randomized controlled trial in prostate cancer patients comparing weekly 2-D portal imaging versus daily 3-D verification.

AIM

To evaluate the clinical outcomes of image guided radiotherapy by presenting rectal and urinary side effects, health related quality of life and progression free survival after 5-years follow up of a randomized controlled trial.

METHODS

We randomized 260 men with intermediate or high-risk prostate cancer to weekly 2-D portal imaging with 15 mm margin from CTV to PTV (Arm A) or daily 3-D cone-beam computer tomography with 7 mm margins (Arm B). Prescribed doses were 78 Gy/39 fractions. All patients received hormonal therapy. Primary end point was patient reported bowel symptoms and secondary outcomes were patient reported urinary symptoms, health- related quality of life and progression free survival.

RESULTS

Of the 216 patients available for analyses at 5 years more than 90 % completed patient reported outcome measures. There were no significant differences between study arms for any single items nor scales evaluating bowel symptoms. There were also no differences in self-reported urinary symptoms nor in health-related quality of life. Symptom scores were low in both study arms. Progression free survival was similar in Arm B as compared to arm A (Hazard ratio 1.01; 95 % CI 0.57 to 1.97).

CONCLUSIONS

Our results support that both 2-D weekly and 3-D daily image guided radiotherapy are safe and efficient treatments for PC and emphasize the need to evaluate technological progress in clinical trials with long follow-up.

Work status changes and associated factors in a nationwide sample of Norwegian long-term breast cancer survivors

PURPOSE

The study aims to describe work status at diagnosis and 8 years post-diagnosis in a nationwide sample of breast cancer survivors (BCSs), and investigate associated and self-reported factors of reduced work status.

METHODS

Women aged 20-65 years when diagnosed with stage I-III breast cancer (BC) in 2011 or 2012 were invited to participate in a questionnaire study in 2019 (n = 2803), of whom 49% (n = 1361) responded. For this sub-study, we included 974 BCSs below the legal retirement age in Norway (< 67 years) at survey and with complete work status data. Reduced work status was defined as being in paid work at BC diagnosis and not working at time of survey. Logistic regression analyses were applied to identify factors associated with reduced work status.

RESULTS

Of BCSs who were in paid work at diagnosis (n = 845), 63% maintained their work status to 8 years later. Reduced work status was associated with not living with children (OR .44, 95% CI .24-.82), age (OR 1.16, 95% CI 1.11-1.21), chemotherapy (OR 2.83, 95% CI 1.24-6.61), > 2 comorbid conditions (OR 2.27, 95% CI 1.16-4.32), cognitive function (OR .99, 95% CI .98-.99), fatigue (OR 1.02, 95% CI 1.01-1.03), and neuroticism (OR 1.57, 95% CI 1.00-2.46). BC and late effects were reported as reasons for reduced work status and disability.

CONCLUSIONS

The majority of BCSs who were in paid work at diagnosis were working 8 years later.

IMPLICATIONS FOR CANCER SURVIVORS

Our results suggest a need to focus on fatigue and reduced cognitive function among long-term BCSs, with the ultimate aim of improving work sustainability.

The association between age and long-term quality of life after curative treatment for prostate cancer: a cross-sectional study

OBJECTIVE

We aimed to investigate the associations between age at radical prostate cancer treatment and long-term global quality of life (QoL), physical function (PF), and treatment-related side effects.

MATERIAL AND METHODS

This single-center, cross-sectional study included men treated for localized prostate cancer with robotic-assisted radical prostatectomy (RARP) or external beam radiotherapy (EBRT) in 2014-2018. Global QoL and PF were assessed by the European Organisation of Research and Treatment in Cancer Quality of life Questionnaire-C30 (QLQ-C30), side effects by the Expanded Prostate Cancer Index Composite (EPIC-26). Adjusted linear regression models were estimated to assess associations between age (continuous variable) at treatment and outcomes. QLQ-C30 scores were compared to normative data after dividing the cohort in two groups, <70 years and ≥70 years at treatment.

RESULTS

Of 654 men included, 516 (79%) had undergone RARP, and 138 (21%) had undergone EBRT combined with androgen deprivation therapy for 93%. Mean time since treatment was 57 months. Median age at treatment was 68 (min-max 44-84) years. We found no statistically significant independent association between age at treatment and global QoL, PF or side effects, except for sexual function (regression coefficient [RC] -0.77; p < 0.001) and hormonal/vitality (RC 0.30; p = 0.006) function. Mean QLQ-C30 scores were slightly poorer than age-adjusted normative scores, for men <70 years (n = 411) as well as for men ≥70 years (n = 243) at treatment, but the differences were not beyond clinical significance.

CONCLUSIONS

In this cohort of prostate cancer survivors, age at treatment had little impact on long-term QoL and function. Due to the cross-sectional design, short term impact or variation over time cannot be ruled out.

Burden of late effects in a nationwide sample of long-term breast cancer survivors

BACKGROUND

Long-term breast cancer survivors (BCSs) may experience several late effects (LEs) simultaneously. This study aimed to identify subgroups of 8-year BCSs with higher burden of LEs who could benefit from closer survivorship care, explore variables associated with higher symptom burden, and describe how symptom burden may affect general functioning.

METHODS

All Norwegian women aged 20 to 65 years when diagnosed with stage I-III breast cancer in 2011 and 2012 were invited (n = 2803). The European Organization for Research and Treatment of Cancer Quality of Life Questionnaire/BR23, the Fatigue Questionnaire, Assessment of Survivor Concerns, and Scale for Chemotherapy Induced Long-term Neurotoxicity were used to assess 10 common LEs and general functioning. Using latent class analysis, subgroups of BCSs with similar burden of LEs were identified. Multinominal regression analysis were performed to examine variables associated with higher symptom burden.

RESULTS

The final sample consisted of 1353 BCSs; 46% had low, 37% medium, and 17% high symptom burden. Younger age, short education, axillary dissection, higher systemic treatment burden, higher body mass index, and physical inactivity were associated with higher symptom burden. General functioning scores were lower, and the proportion on disability pension were higher among BCSs in the two most burdened subgroups compared with those in the low burden subgroup.

CONCLUSION

More than half of long-term BCSs suffered from medium or high symptom burden and experienced impaired general functioning compared with BCS with low symptom burden. Younger age and systemic treatment were important risk factors for higher symptom burden. BCSs at risk of higher symptom burdens should be identified and offered closer and extended survivorship care.

Estimated prevalence of DSM-5 eating disorders in Norwegian adolescents: A community based two-phase study

OBJECTIVE

Little is known about the prevalence of DSM-5 eating disorders (EDs) in adolescents. In Norway, the most recent community-based prevalence study in adolescents was published more than 20 years ago. The aim of this study was to assess the prevalence of DSM-5 EDs in Norwegian adolescents using a two-phase design.

METHOD

A total of 1558 upper secondary school students (827 girls and 730 boys) (ages 16-19) were screened for at-risk ED pathology using the Eating Disorder Examination-Questionnaire short version (EDE-QS). A sub-sample of 99 adolescents (87 girls and 12 boys) subsequently participated in a clinical interview using the Eating Disorder Assessment for DSM-5 (EDA-5).

RESULTS

Eating pathology was common, with 19.9% of participants scoring at or above the applied EDE-QS cut-off. The estimated prevalence of any ED was 9.4% in the total sample, and 16.4% in girls. The number of boys who took part in the diagnostic interview was low, thus, diagnostic data from boys were not analyzed separately. Prevalence estimates of AN, BN, BED, and OSFED in girls were 2.7%, 1.1%, 1.9%, and 10.7%. Atypical AN was the most frequently assigned diagnosis in girls.

DISCUSSION

Sampling biases limit generalizability of results. Additional population-based studies are warranted to assess the prevalence of EDs in Norwegian youth.

PUBLIC SIGNIFICANCE STATEMENT

In this study, 1558 adolescents, aged 16-19, were screened for ED pathology. A subsample completed a diagnostic interview using DSM-5 criteria. Results showed that one in five adolescents displayed problematic eating behaviors and cognitions. The estimated prevalence rate of any ED was 9.4%. Sampling biases limit generalizability of results. Additional population-based studies are warranted to assess the prevalence of EDs in Norwegian youth.

Quality of life of older gynecologic oncology patients at the initiation of chemotherapy

AIM

To evaluate older gynecologic oncology patients' quality of life (QOL) at the initiation of chemotherapy and compare their QOL scores with a female age-matched general population (GP) sample.

DESIGN

Cross-sectional.

METHODS

Older (n = 122) gynecologic oncology patients completed the European Organization for the Research and Treatment of Cancer Quality of Life Questionnaire (QLQ-C30) that evaluates global health and five functional scales (range from 0 to 100). Differences in QOL scores between our sample and the GP were evaluated using one-sample t-tests and effect sizes were calculated using Cohen's d.

RESULTS

Patients' mean age was 70.7 years (±6.6). Mean scores for the function scales ranged from 58.5 (±31.1) for role function to 86.1 (±17.0) for cognitive function. Compared to the GP, our sample reported significantly lower scores for global health status, social, role and physical functioning, and a significantly higher score for cognitive functioning. No differences were found in emotional functioning scores.

PATIENT OR PUBLIC CONTRIBUTION

No patient or public contribution.

Norwegian general population normative data for the European Organization for Research and Treatment of Cancer questionnaires: the Quality of Life Questionnaire-Core 30, the Sexual Health Questionnaire QLQ-SHQ22 and the sexual domains of the QLQ-BR23/BR45

OBJECTIVE

The aim of this study was to provide sex-, age-, and morbidity-specific Norwegian general population normative values for the European Organization for Research and Treatment of Cancer Quality of Life Questionnaires QLQ-C30, the sexual health questionnaire QLQ-SHQ22 and the sexual domains of the breast modules QLQ-BR23 and QLQ-BR45.

METHODS

A random nationwide sample stratified by sex and age groups (18-29, 30-39, 40-49, 50-59, 60-69 and ≥70 years) was drawn from the Norwegian National Population Register. Participants were notified through national online health services (HelseNorge) and postal mail. The survey included sociodemographic background information, health-related quality of life assessed by the EORTC questionnaires, and morbidity assessed by the Self-Administered Comorbidity Questionnaire. Multivariable linear regression was carried out to estimate the associations of age, sex and morbidity with the EORTC scale and item scores.

RESULTS

Of the 15,627 eligible individuals, 5135 (33%) responded. Women and persons with morbidities reported lower functioning and higher symptom burden than men and persons without morbidities, respectively, on nearly all EORTC scales. Sex differences were most prominent for emotional functioning, pain, fatigue and insomnia (QLQ-C30), body image, sexual functioning (QLQ-BR23/45), importance of sexual activity, libido and fatigue (QLQ-SHQ22). The score differences between persons with and without morbidity were highly significant and largest in the youngest and middle-aged groups.

CONCLUSION

This is the first study to provide normative values for the EORTC sexual health questionnaire QLQ-SHQ22 and the sexual subscales of the QLQ-BR23 and QLQ-BR45 for all, separately in age groups by sex and morbidity.

Updated normative data for the EORTC QLQ-C30 in the general Dutch population by age and sex: a cross-sectional panel research study

PURPOSE

The European Organisation for Research and Treatment of Cancer (EORTC) quality of life core questionnaire (QLQ-C30) is a validated and widely-used Patient-Reported Outcome Measure for measuring the health-related quality of life (HRQoL) of cancer patients. To facilitate interpretation of results obtained in studies using the EORTC QLQ-C30, we generated normative data for the Dutch general population, stratified by age and sex.

METHODS

Dutch participants were selected from a larger cross-sectional online panel research study collecting EORTC QLQ-C30 general population normative data across 15 countries. EORTC QLQ-C30 raw scores based on a 4-point response scale were transformed to linear scores ranging from 0 to 100. Transformed scores were weighted based on the United Nations population distribution statistics and presented by age and sex/age. Differences in scale scores of ≥ 10 points in HRQoL were applied to indicate clinical relevance.

RESULTS

One thousand respondents completed the online survey. Stratified by age, clinically meaningful differences were observed, with worse physical functioning scores and better emotional functioning scores with increased age. Symptom scores remained stable across age groups, except for small age differences observed for fatigue, nausea/vomiting, diarrhoea, and financial difficulties. Stratified by sex/age, men generally scored better for both functioning and symptoms. However, these differences were not clinically meaningful.

CONCLUSIONS

These updated normative EORTC QLQ-C30 for the Dutch general population can be used to better interpret HRQoL data obtained from Dutch cancer patients. Being part of a larger international study, these data can further be used for inter-country comparisons in multi-national studies.

A study of modifiable factors associated with health-related quality of life in long-term cervical cancer survivors

INTRODUCTION

Health-related quality of life (HR-QoL) in cancer survivors is relevant for symptom relief and optimal care. The aim of this cross-sectional study of long-term cervical cancer survivors was two-fold: (a) To compare HR-QoL in long-term cervical cancer survivors with reference data; and (b) to identify modifiable factors significantly associated with low levels of generic cancer HR-QoL in long-term cervical cancer survivors using high HR-QoL as reference.

MATERIAL AND METHODS

Women treated for cervical cancer from 2000 through 2007 who were cancer-free and alive in 2013 received a mailed questionnaire including scales for anxiety, depression, and HR-QoL. To obtain a homogeneous sample only women with FIGO stages 1 and 2 were included. The questionnaire included the European Organization for Research and Treatment of Cancer Quality of Life Questionnaire.C-30 (EORTC QLQ C-30) for generic HR-QoL. Groups with high and low HR-QoL were defined by the median score on the general HR-QoL item. Between-group differences were examined with descriptive statistics. Logistic regression analyses examined independent variables associated with low generic HR-QoL.

RESULTS

Complete C-30 scores were delivered by 472 long-term cervical cancer survivors. Median age at survey was 53 (interquartile range 14.9) years, and median time since diagnosis was 11 (interquartile range 3.9) years. The proportion of survivors with stage 1 disease was 83% and stage 2 was 17%. Mean generic HR-QoL scores showed minor differences between long-term cervical cancer survivors and reference data. In the multivariable analysis, only modifiable variables remained significantly associated with low generic HR-QoL namely self-rated health, probable depression, fatigue, and pain. In bivariate analyses other modifiable variables also showed significant associations with low generic HR-QoL like probable anxiety disorder, obesity, smoking, sleep disturbances, and bowel symptoms.

CONCLUSIONS

Clinicians should be aware that generic HR-QoL in long-term cervical cancer survivors eventually may be improved by identification and treatment of modifiable factors through the whole follow-up period.

Quality of life in patients with achalasia: Associations with Eckardt score and objective treatment outcomes after peroral endoscopic myotomy

Background and study aims  Knowledge on self-reported quality of life (QoL) in achalasia and QoL improvements after peroral endoscopic myotomy (POEM) is limited. Furthermore, the clinical role of QoL in achalasia follow-up has not been evaluated. The present study aimed to examine QoL in achalasia patients before and after POEM and assess associations between QoL, Eckardt score (ES) and objective results. Patients and methods  This was a single-center prospective study of treatment-naïve achalasia patients with 12-month follow-up after POEM including manometry, upper endoscopy, 24-hour pH registration, and timed barium esophagogram. QoL data were registered using European Organisation for Research and Treatment of Cancer core questionnaire (QLQ-C30) and esophageal module (QLQ-OES18). Comparison with a reference population was performed to assess impact of achalasia on QoL and effect of therapy. Mixed models for repeated measures were applied. Results  Fifty patients (26 females) with a median age of 47 years (18-76) were included. Before treatment, all QoL domains were significantly impaired compared with an age- and gender-adjusted reference population ( P  < 0.05). No significant QoL-differences were found after POEM, except for fatigue and nausea/vomiting. Clinically relevant QoL improvement was observed in ≥ 50 % of the patients in all QoL domains, except for physical and role functioning. QoL was significantly associated with ES ( P  < 0.05) but not with objective results. Conclusions  Achalasia is associated with severe QoL impairment. Following POEM, a significant and clinically relevant QoL improvement is observed. QoL is associated with ES, but not with objective results after POEM.

Work ability 8 years after breast cancer: exploring the role of social support in a nation-wide survey

INTRODUCTION

As the 5-year survival rate after breast cancer in Norway is 92%, the population of breast cancer survivors (BCSs) is increasing. Knowledge of work ability in this population is scarce. In a population-based cohort of BCSs, we explored work ability 8 years after diagnosis and the association between work ability and social support, and cancer-related variables including late effects and lifestyle factors.

METHODS

In 2019, all Norwegian women < 59 years when diagnosed with stage I-III breast cancer in 2011 or 2012, were identified by the Cancer Registry of Norway and invited to participate in a survey on work life experiences. Work ability was assessed using the Work Ability Index (scale 0-10). Factors associated with excellent work ability (score ≥ 9) were identified using univariate and multivariate logistic regression analyses, and adjusted for socioeconomic-, health- and cancer-related variables.

RESULTS

Of the 1951 eligible BCSs, 1007 (52.8%) responded. After excluding survivors with relapse (n = 1), missing information on work ability score (n = 49), or work status (n = 31), the final sample comprised 926 BCSs within working age at survey (< 67 years). Mean age at survey was 56 years and 8 years (SD 0.7) had passed since diagnosis. Work ability had been reduced from 8.9 (SD 2.3) at diagnosis to 6.3 (SD 3.1). One in three BCSs reported poor work ability (WAS ≤ 5), and seven out of ten reported that their physical work ability had been reduced due to cancer. Social support from colleagues during cancer therapy was associated with excellent work ability, which was not observed for social support provided by supervisors or the general practitioner. Cognitive impairment and fatigue were inversely associated with work ability. None of the cancer-related variables, including treatment, were associated with work ability 8 years after diagnosis.

CONCLUSION

In this population-based sample, one in three BCSs reported poor work ability 8 years after diagnosis. Collegial social support during cancer therapy appears to be a protective factor for sustained work ability, whilst survivors struggling with fatigue and cognitive impairments may represent a particularly vulnerable group for reduced work ability.

Pretreatment patient-reported cognitive function in patients with diffuse glioma

Purpose

Cognitive function is frequently assessed with objective neuropsychological tests, but patient-reported cognitive function is less explored. We aimed to investigate the preoperative prevalence of patient-reported cognitive impairment in patients with diffuse glioma compared to a matched reference group and explore associated factors.

Methods

We included 237 patients with diffuse glioma and 474 age- and gender-matched controls from the general population. Patient-reported cognitive function was measured using the cognitive function subscale in the European Organisation for Research and Treatment of Cancer QLQ-C30 questionnaire. The transformed scale score (0–100) was dichotomized, with a score of ≤ 75 indicating clinically important patient-reported cognitive impairment. Factors associated with preoperative patient-reported cognitive impairment were explored in a multivariable regression analysis.

Results

Cognitive impairment was reported by 49.8% of the diffuse glioma patients and by 23.4% in the age- and gender-matched reference group (p < 0.001). Patients with diffuse glioma had 3.2 times higher odds (95% CI 2.29, 4.58, p < 0.001) for patient-reported cognitive impairment compared to the matched reference group. In the multivariable analysis, large tumor volume, left tumor lateralization, and low Karnofsky Performance Status score were found to be independent predictors for preoperative patient-reported cognitive impairment.

Conclusions

Our findings demonstrate that patient-reported cognitive impairment is a common symptom in patients with diffuse glioma pretreatment, especially in patients with large tumor volumes, left tumor lateralization, and low functional levels. Patient-reported cognitive function may provide important information about patients’ subjective cognitive health and disease status and may serve as a complement to or as a screening variable for subsequent objective testing.

Longitudinal effects of adjuvant chemotherapy and lymph node staging on patient-reported outcomes in endometrial cancer survivors: a prospective cohort study

BACKGROUND

Most patients with endometrial cancer with localized disease are effectively treated and survive for a long time. The primary treatment is hysterectomy, to which surgical staging procedures may be added to assess the need for adjuvant therapy. Longitudinal data on patient-reported outcomes comparing different levels of primary treatment are lacking, especially when adjuvant radiotherapy is omitted.

OBJECTIVE

We assessed the impact of lymphadenectomy and adjuvant chemotherapy on patient-reported symptoms, function, and quality of life. We hypothesized that these treatment modalities would substantially affect patient-reported outcomes at follow-up.

STUDY DESIGN

We prospectively included patients with endometrial cancer enrolled in the ongoing MoMaTEC2 study (ClinicalTrials.gov Identifier: NCT02543710). Patients were asked to complete the patient-reported outcome questionnaires European Organization for Research and Treatment of Cancer Quality of Life Questionnaire C30 and European Organization for Research and Treatment of Cancer Quality of Life Questionnaire EN24 preoperatively and at 1 and 2 years of follow-up. Functional domains and symptoms were analyzed for the whole cohort and by treatment received. To assess the effect of the individual treatment modifications, we used mixed regression models.

RESULTS

Baseline data were available for 448 patients. Of these patients, 339 and 219 had reached 1-year follow-up and 2-year follow-up, respectively. Treatment included hysterectomy (plus bilateral salpingo-oophorectomy) alone (n=177), hysterectomy and lymph node staging without adjuvant therapy (n=133), or adjuvant chemotherapy irrespective of staging procedure (n=138). Overall, patients reported improved global health status and quality of life (+9 units; P<.001), increased emotional and social functioning, and increased sexual interest and activity (P<.001 for all) from baseline to year 1, and these outcomes remained stable at year 2. Means of functional scales and quality of life were similar to age- and sex-weighted reference cohorts. Mean tingling and numbness and lymphedema increased after treatment. The group who received adjuvant chemotherapy had a larger mean reduction in physical functioning (-6 vs +2; P=.002) at year 1, more neuropathy (+30 vs +5; P<.001; year 1) at years 1 and 2, and more lymphedema at year 1 (+11 vs +2; P=.007) than the group treated with hysterectomy and salpingo-oophorectomy only. In patients not receiving adjuvant chemotherapy, patient-reported outcomes were similar regardless of lymph node staging procedures. Adjuvant chemotherapy independently increased fatigue, lymphedema, and neuropathy in mixed regression models.

CONCLUSION

Patients with endometrial cancer receiving adjuvant chemotherapy reported significantly reduced functioning and more symptoms up to 2 years after treatment. For patients treated by surgery alone, surgical staging did not seem to affect the quality of life or symptoms to a measurable degree at follow-up. Therefore, subjecting patients to lymph node removal to tailor adjuvant therapy seems justified from the patient's viewpoint; however, efforts should increase to find alternatives to traditional chemotherapy.

Age-related differences in self-report and objective measures of cognitive function in older patients prior to chemotherapy

Aim

Evaluate for differences in demographic and clinical characteristics and subjective and objective measures of cognitive function (CF) between younger older adults (YOA, 60–69 years) and older adults (OA, ≥70 years).

Design

Cross‐sectional.

Methods

Older oncology patients (n = 139) completed subjective (Attentional Function Index, European Organization for the Research and Treatment of Cancer Quality of Life Questionnaire (EORTC) CF scale) and objective (Montreal Cognitive Assessment, Trail Making Test (TMT) A & B) measures of CF prior to chemotherapy. Data were analyzed using parametric and nonparametric tests.

Results

No differences were found between the two groups for any of the subjective or objective CF measures, except that OA patients had higher TMT B scores. Compared with the general population, OAs had significantly higher EORTC CF scores and YOAs had significantly worse scores for all of the objective tests. Clinically meaningful difference between group differences was found for the TMT B test.

Comorbidities, Rather Than Older Age, Are Strongly Associated With Higher Utilization of Healthcare in Colorectal Cancer Survivors

BACKGROUND

Colorectal cancer (CRC) survivors generally have a higher healthcare utilization (HCU) than the general population due to cancer burden. However, it is unclear which factors are associated with this increased uptake. Our study aimed to (1) compare CRC-related and non-CRC visits to general practitioners (GPs) and medical specialists (MSs) by comorbidities, and (2) assess whether HCU differs by demographic, clinical, and psychological factors.

METHODS

We used data from a German population-based cohort of 1,718 survivors of stage I-III CRC diagnosed in 2003 through 2010 who provided information on HCU at 5-year follow-up. Multivariable linear regression was used to calculate least-square means of CRC-related and non-CRC HCU according to the Charlson comorbidity index and comorbidity cluster, adjusting for relevant demographic, clinical, and psychological characteristics.

RESULTS

A higher comorbidity level was associated with more CRC-related MS visits and non-CRC GP visits. In addition to being strongly associated with non-CRC GP visits, comorbidity clusters were associated with CRC-related GP and MS visits, but their association varied by specific cardiometabolic comorbidities. HCU was less dependent on prognostic factors for CRC, such as age and tumor stage, but was strongly associated with disease recurrence, depression, and emotional functioning.

CONCLUSIONS

Comorbidities, rather than age or tumor stage, were related to HCU, suggesting that CRC survivors use healthcare mainly for reasons other than cancer 5 years postdiagnosis. Improved communication between primary and tertiary healthcare providers could enhance the medical care of cancer survivors with complex health needs and thereby also reduce healthcare costs.

Common and distinct characteristics associated with self-reported functional status in older patients with cancer receiving chemotherapy

PURPOSE

To evaluate for inter-individual differences in two subjective measures of functional status in older patients (n = 112), as well as to determine which demographic, clinical, and symptom characteristics, and levels of cognitive function, were associated with initial levels and with the trajectory of the two measures.

METHODS

Functional status was assessed using self-report measures of physical function (PF) and role function (RF) from the European Organization for Research and Treatment of Cancer Core Quality-of-Life Questionnaire at the initiation of chemotherapy and at 1, 3, 6, 9, and 12 months after its initiation. Hierarchical linear modeling was used to assess inter-individual differences in and characteristics associated with initial levels and changes in PF and RF.

RESULTS

Characteristics associated with decreases in PF at the initiation of chemotherapy were higher numbers of comorbidities and higher depression, pain, and dyspnea scores. For initial levels of poorer RF, lower Karnofsky Performance Status scores and higher pain and fatigue scores were the associated characteristics. Characteristic associated with worse trajectories of PF was not having had surgery. For RF, worse trajectories were associated with lower cognitive function and higher RF at enrollment. Characteristic associated with both lower initial levels and improved trajectories of PF was having lower performance status at enrollment.

CONCLUSIONS

Older patients undergoing chemotherapy experience reduced functional performance. Characteristics associated with decrements in PF and RF need to be assessed and interventions implemented to maintain and increase functional status in older oncology patients.

General Spanish population normative data analysis for the EORTC QLQ-C30 by sex, age, and health condition

Purpose

General population normative data for the European Organisation for Research and Treatment of Cancer (EORTC) QLQ-C30 questionnaire facilitates interpretation of data assessed from cancer patients. This study aims to present normative data of the general Spanish population.

Methods/patients

Data were obtained from a prior larger study collecting EORTC QLQ-C30 norm data across 15 countries. Data were stratified by sex and age groups (18–39, 40–49, 50–59, 60–69 and > 70 years). Sex and age distribution were weighted according to population distribution statistics. Sex- and age-specific normative values were analysed separately, as were participants with versus those without health conditions. Multiple linear regression was used to estimate the association of each of the EORTC QLQ-C30 scales with the determinants age, sex, sex-by-age interaction term, and health condition.

Results

In total, 1,165 Spanish individuals participated in the study. Differences were found by sex and age. The largest sex-related differences were seen in fatigue, emotional functioning, and global QOL (Quality of Life), favouring men. The largest age differences were seen in emotional functioning, insomnia, and pain, with middle-aged groups having the worst scores. Those > 60 years old scored better than those < 60 years old on all scales except for physical functioning. Participants with no health conditions scored better in all QLQ-C30 domains.

Conclusions

The present study highlights differences in HRQOL between specific sex/age strata and especially between people with and without a health condition in the general Spanish population. These factors must be considered when comparing general population HRQOL data with that of cancer patients.

Distinctions Between Self-Report and Performance-Based Measures of Physical Function in Older Patients Prior to Chemotherapy

BACKGROUND

The maintenance of physical function (PF) is an extremely important outcome for elderly people.

OBJECTIVE

The aims of this study were to identify differences in the subjective and objective measures of PF between younger older adults (YOAs, 60-69 years of age) and older adults (OA, ≥70 years of age), to compare the PF scores with age-matched samples from the general population, and to evaluate for associations between the subjective and objective measures of PF.

METHODS

Patients (n = 139) were assessed using subjective (ie, European Organization for Research and Treatment of Cancer Core Quality-of-Life Questionnaire) and objective (ie, Short Physical Performance Battery [SPPB]) measures prior to chemotherapy (CTX). Data were analyzed using parametric and nonparametric tests.

RESULTS

No differences were found between the 2 age groups in any of the subjective or objective measures of PF. Compared with the age-matched general population, both YOAs and OAs had significantly lower scores in both measures of PF. Large effect sizes were found for differences in European Organization for Research and Treatment of Cancer Core Quality-of-Life Questionnaire role function, SPPB balance, and SPPB total scores between the YOA group and the age-matched general population samples. Correlations between the subjective and objective measures were low.

CONCLUSIONS

Older patients with cancer have lower PF than their age-matched general population prior to CTX. Longitudinal studies are warranted to evaluate for changes in PF during and following CTX.

IMPLICATIONS FOR PRACTICE

Nurses need to perform routine assessments of PF in older oncology patients prior to CTX. Our findings suggest that SPPB gait speed may be a useful screening measure for PF in older patients.

Rasch Analysis of the Norwegian Version of the Occupational Balance Questionnaire in a Sample of Occupational Therapy Students

Background

Recently, the Occupational Balance Questionnaire developed in Sweden was translated into Norwegian. No studies to date have examined the measurement properties of the Norwegian version of this questionnaire.

Aim

The study is aimed at examining the psychometric properties of the Norwegian version of the Occupational Balance Questionnaire, the OBQ11-N.

Methods

Along with sociodemographic data, 180 occupational therapy students enrolled at two Norwegian universities completed the OBQ11-N as well as one question each related to health and quality of life and some sociodemographic variables. Rasch analysis was employed for examining rating scale functioning, item and person validity, dimensionality, and differential item functioning.

Results

Item categories were ordered, but there were potential gaps in the measurement of the construct. Person reliability was fair, whereas item reliability was low. Point biserial correlations were positive, indicating that all items contributed to the construct. Factor loadings were low for two items, and there were indices of a second underlying dimension and item redundancy. Many people were not aligned with the items, and some items functioned differently across various demographic variables. Conclusion and Significance. The OBQ11-N did not function as an adequate measure of occupational balance in a sample of students. Potentially, the detected measurement problems may be solved by adding more relevant items to a larger item pool, from which the best fitting items should be selected.

Symptoms in the general Norwegian adult population - prevalence and associated factors

BACKGROUND

Patients´ own perceptions and evaluations of symptoms, functioning and other health-related factors, i.e. Patient Reported Outcomes (PROs), are important elements for providing good patient care. Symptoms are subjective and best elicited by the patient orally or by using PRO measures (PROMs), be it on paper, or as electronic assessment tools. Reference values on frequently used PROMs facilitate the interpretation of scores for use in clinics and research settings, by comparing patient data with relevant samples from the general population. Study objectives were to (1) present reference values for the M.D. Anderson Symptom Inventory (MDASI) (2) examine the occurrence and intensity of symptoms assessed by the MDASI in a general Norwegian adult population sample, and (3) examine factors associated with higher symptom burden defined as the sum score of all symptoms, and factors associated with symptoms` interference on functions.

METHODS

In 2015, MDASI was sent by mail as part of a larger survey, to a representative sample of the general Norwegian adult population (N = 6165). Medical comorbidities were assessed by the Self-Administered Comorbidity Questionnaire. Depression was self-reported on the Patient Health Questionnaire 9 (PHQ-9). Linear multivariable regression analysis was used to examine for factors associated with MDASI sum score and factors associated with symptoms' interference on functions.

RESULTS

The response rate was 36%. More women (54%) than men (46%) responded. Mean age was 55 years (SD 14). The most frequent symptoms were fatigue (59.7%), drowsiness (56.2%) and pain (56.1%). Fatigue, pain and disturbed sleep had the highest mean scores. The presence of one or more comorbidities, increasing PHQ-9 score and lower level of education were associated with higher MDASI sum score (p < 0.001). The MDASI sum score and the PHQ-9 score were positively associated with all interference items (p < 0.001) except for walking (p = 0.22).

CONCLUSION

This study provides the first Norwegian reference values for MDASI. The presence of one or more comorbidities, higher level of depressive symptoms and lower level of education were significantly associated with higher MDASI sum score. These covariates must be controlled for when using the reference values.

Personality and educational level determine self-reported health-related quality-of-life and distress in patients with renal tumors awaiting radical surgery

Objective: Data on preoperative distress and health-related quality-of-life (HRQoL) is lacking for patients with newly diagnosed renal tumors. This study aims to compare HRQoL within this group with the general population and to study the relationship between distress, HRQoL, personality, coping, and patient/tumor-related factors.Materials and methods: Between January 2011 and June 2014, 153 patients (100 males/53 females), scheduled for surgery were prospectively included. Distress was determined by the General Health Questionnaire (GHQ), HRQoL by EORTC-QLQ-C30 questionnaire, personality by Eysenck Personality Inventory and coping by COPE questionnaire. HRQoL-data from an age and gender matched Norwegian reference population was used for comparison.Results: The study patients had significantly poorer HRQoL than the reference population. GHQ and HRQoL sum scores had a common variance (CV = r²) of 29-35%. In regression models, the measured variables accounted for 33% of the variance for the GHQ score. Significant predictors of the measured variance were neuroticism (18%), education level (3%) and avoidant coping (2%). Similarly, the measured variables accounted for 33-44% of the variance for the HRQoL sum scores. For all HRQoL sum scores, neuroticism predicted 17-28%, while education predicted 4-11% of the measured variance. Large tumor size, comorbidity, performance status and CRP predicted 2-7% of individual sum scores.Conclusions: For both preoperative distress and HRQoL, personality traits such as neuroticism and education level were the most important predictors. Tumor-related factors and other preexisting conditions seemed to be of lesser importance. Thus, preoperatively screening of psychological factors could be helpful to identify those at risk of poor outcomes.

The Influence of Comorbidity on Health-Related Quality of Life After Esophageal Cancer Surgery

BACKGROUND

Esophageal cancer surgery reduces patients' health-related quality of life (HRQoL). This study examined whether comorbidities influence HRQoL in these patients.

METHODS

This prospective cohort study included esophageal cancer patients having undergone curatively intended esophagectomy at St Thomas' Hospital London in 2011-2015. Clinical data were collected from patient reports and medical records. Well-validated cancer-specific and esophageal cancer-specific questionnaires (EORTC QLQ-C30 and QLQ-OG25) were used to assess HRQoL before and 6 months after esophagectomy. Number of comorbidities, American Society of Anesthesiologists physical status classification (ASA), and specific comorbidities were analyzed in relation to HRQoL aspects using multivariable linear regression models. Mean score differences with 95% confidence intervals were adjusted for potential confounders.

RESULTS

Among 136 patients, those with three or more comorbidities at the time of surgery had poorer global quality of life and physical function and more fatigue compared with those with no comorbidity. Patients with ASA III-IV reported more problems with the above HRQoL aspects and worse social function and pain compared with those with ASA I-II. Cardiac comorbidity was associated with worse global quality of life and dyspnea, while pulmonary comorbidities were related to coughing. Patients assessed both before and 6 months after surgery (n = 80) deteriorated in most HRQoL aspects regardless of comorbidity status, but patients with several comorbidities had worse physical function and fatigue and more trouble with coughing compared with those with fewer comorbidities.

CONCLUSION

Comorbidity appears to negatively influence HRQoL before esophagectomy, but appears not to severely impact 6-month recovery of HRQoL.

Self-rated global health in the Norwegian general population

Background

Prevalence studies are needed to assess the distribution of diseases. However, in a contrasting health promotion perspective, self-rated health is in itself an important field of study. This study investigated self-rated global health in the general population in Norway.

Methods

As part of a national survey, a two-item measure of global health (score range 0–100) was administered to a general population sample, and 1776 of 4961 eligible participants (response rate 36%) responded. Group comparisons were conducted using independent t-tests and one-way analyses of variance, whereas factors associated with global health was investigated with linear regression analysis.

Results

In the adjusted analyses, better global health was associated with higher age (β = 0.13, p <  0.001), having higher education (β = 0.10, p <  0.001), being employed (β = 0.21, p <  0.001), and living with a spouse or partner (β = 0.05, p <  0.05).

Conclusions

While global health was similar for men and women in the Norwegian general population, other sociodemographic variables were linked with global health. In particular, the link between employment and self-rated global health was strong. The findings are considered representative for the Norwegian population.

Factors related to health-related quality of life in ankylosing spondylitis, overall and stratified by sex

Background

Ankylosing spondylitis (AS) begins early in life and often leads to reduced physical function, but less is known about the impacts it has on health-related quality of life (HRQoL). The aims of this study were to assess HRQoL using the Short Form-36 (SF-36) in a cohort of patients with AS compared with controls and to examine associations between SF-36 scores and spinal radiographic changes, physical function, disease activity and demographic data overall and stratified by sex.

Methods

A cohort of patients with AS from Western Sweden were assessed using the Modified Stoke Ankylosing Spondylitis Spine Score (mSASSS) with spinal radiographs, clinical examination and questionnaires, including the Bath Ankylosing Spondylitis Metrology Index, Bath Ankylosing Spondylitis Functional Index (BASFI), Ankylosing Spondylitis Disease Activity Score-C-reactive protein (ASDAS-CRP), Bath Ankylosing Spondylitis Disease Activity Index, Bath Ankylosing Spondylitis Patient Global (BASG) and SF-36. Each patient’s SF-36 results were compared with those of five age-matched and sex-matched persons (n = 1055) from the SF-36 Swedish normative population database. Associations between SF-36 physical component summary (PCS) and mental component summary (MCS) scores and disease-related and demographic factors were investigated using univariate and multivariable ogistic regression analyses with PCS and MCS below/above their respective median values as dependent variables.

Results

A total of 210 patients, age (median, IQR) 49.0 (21.2) years, symptom duration 24.0 (21.0) years, men 57.6% and HLAB27 87.1% were included. Patients with AS scored significantly lower (p < 0.001) compared to controls in all SF-36 domains and component summaries; PCS 42.4 (14.5) in AS versus 52.4 (11.8) in controls and MCS 47.9 (20.0) in AS versus 54.1 (10.1) in controls. Both men and women scored significantly lower in PCS compared with MCS. Multivariable logistic regression analyses revealed that living without a partner (OR 2.38, 95% CI 1.00–5.67), long symptom duration (year in decade OR 1.66, 95% CI 1.16–2.37), higher BASFI (OR 1.98, 95% CI 1.46–2.70) and ASDAS ≥ 2.1 (OR 3.32, 95% CI 1.45–7.62) were associated with worse PCS, while living without a partner (OR 3.04, 95% CI 1.34–6.91), fatigue (visual analogue scale for global fatigue greater than the median (OR 6.36, 95% CI 3.06–13.19) and ASDAS ≥ 2.1 (OR 2.97, 95% CI 1.41–6.25) with worse MCS. Some differences between sexes were observed in the results.

Conclusions

The patients with AS had significantly lower HRQoL compared with controls. PCS was more affected compared to MCS in both sexes. Both disease-related and demographic factors were associated with HRQoL, partly overlapping for PCS and MCS. Factors associated with HRQoL showed some differences between sexes. By modifying factors, such as ASDAS-CRP and fatigue, HRQoL may potentially be improved.

Norwegian reference values for the Short-Form Health Survey 36: development over time

Purpose

Reference values for patient-reported outcome measures are useful for interpretation of results from clinical trials. The study aims were to collect Norwegian SF-36 reference values and compare with data from 1996 to 2002.

Methods

In 2015, SF-36 was sent by mail to a representative sample of the population (N = 6165). Time trends and associations between background variables and SF-36 scale scores were compared by linear regression models.

Results

The 2015 response rate was 36% (N = 2118) versus 67% (N = 2323) in 1996 and 56% (N = 5241) in 2002. Only 5% of the youngest (18–29 years) and 27% of the oldest (>70 years) responded in 2015. Age and educational level were significantly higher in 2015 relative to 1996/2002 (p < .001). The oldest age group in 2015 reported better scores on five of eight scales (p < 0.01), the exceptions being bodily pain, vitality, and mental health compared to 1996/2002 (NS). Overall, the SF-36 scores were relatively stable across surveys, controlled for background variables. In general, the most pronounced changes in 2015 were better scores on the role limitations emotional scale (7.4 points, p < .001) and lower scores on the bodily pain scale (4.6 points, p < .001) than in the 1996/2002 survey.

Conclusions

The low response rate in 2015 suggests that the results, especially among the youngest, should be interpreted with caution. The high response rate among the oldest indicates good representativity for those >70 years. Despite societal changes in Norway the past two decades, HRQoL has remained relatively stable.

Differential Impact of Symptom Prevalence and Chronic Conditions on Quality of Life in Cancer Survivors and Non-Cancer Individuals: A Population Study

Background: To compare associations of symptom prevalence, chronic conditions, and health-related quality of life (HRQOL) between cancer survivors and non-cancer individuals using the U.S. National Health Interview Survey.Methods: Study samples comprised 604 survivors and 6,166 non-cancer individuals. Symptoms included sensation abnormality, pain, fatigue, cognitive disturbance, depression, and anxiety. Physical and mental HRQOL was measured by the Patient-Reported Outcomes Measurement Information System.Results: Compared with non-cancer individuals, survivors had higher prevalence in sensation abnormality (OR = 2.4; 95% CI = 1.9 to 3.0), pain (OR = 2.1; 95% CI = 1.7 to 2.6), fatigue (OR = 1.4; 95% CI = 1.1 to 1.8), and decremented physical HRQOL (difference = -3.7; 95% CI = -4.7 to -2.6). The prevalence of individual symptoms was significantly associated with decremented physical HRQOL [range = -5.9 (anxiety) to -8.9 (pain)] and mental HRQOL [range = -4.7 (sensation) to -8.4 (depression)]. The association between cancer experience and physical and mental HRQOL was chiefly explained by the prevalence of six symptoms and presence of chronic conditions. Pain (β = -4.0; 95% CI = -4.5 to -3.6) and ≥2 chronic conditions (β = -9.2; 95% CI = -10.2 to -8.2) significantly decremented physical HRQOL. Depression (β = -5.2; 95% CI = -5.8 to -4.6) and ≥2 chronic conditions (β = -3.3; 95% CI = -4.4 to -2.3) significantly decremented mental HRQOL.Conclusions: Cancer survivors experience more symptom burden than non-cancer individuals, which is associated with more chronic conditions and impaired HRQOL.Impacts: Interventions to manage symptom prevalence especially for older cancer survivors and survivors with more chronic conditions may improve their HRQOL outcomes.

Health-related Quality of Life Assessed by the EORTC QLQ-C30 Questionnaire in the General Slovenian Population

Background

The aim of our study was to obtain reference data of the EORTC QLQ-C30 quality of life dimensions for the general Slovenian population. We intend to provide the researchers and clinicians in our country with the expected mean health-related quality of life (HRQL) scores for distinctive socio-demographic population groups.

Methods

The EORTC QLQ-C30 questionnaire supplemented by a socio-demographic inquiry was mailed or distributed to 1,685 randomly selected individuals in the Slovenian population aged 18 – 90. Answers from 1,231 subjects representing socio-demographic diversity of the Slovenian population were collected and transformed into EORTC dimensions and symptoms. The impact of socio-demographic features on HRQL scores was assessed by multiple linear regression models.

Results

Gender, age and self-rated social class are the important confounders in the quality of life scores in our population. Men reported better quality of life on the majority of the specific scales and, at the same time, reported fewer symptoms. There was no gender-specific difference in cognitive functioning. The mean scores were consistently lower with age in both sexes.

Conclusions

This is the first study to report the normative EORTC QLQ-C30 scores for one of the south-eastern European populations. The reported expected mean scores allow Slovenian oncologists to estimate what the quality of life in cancer patients would be, had they not been ill. As they are derived by common methodology, our results can easily be included in any further international comparisons or in the calculation of European summarized HRQL scores.

Health-related quality of life, anxiety and depression in the diagnostic phase of suspected cancer, and the influence of diagnosis

Background

Undergoing diagnostic evaluation for cancer has been associated with a high prevalence of anxiety and depression and affected health-related quality of life (HRQoL). The aims of this study were to assess HRQoL, anxiety, and depression pre- and post-diagnosis in patients undergoing diagnostic evaluations for cancer due to non-specific symptoms; to examine changes over time in relation to final diagnosis (cancer yes/no); and to assess the predictive value of pre-diagnostic psychological, socio-demographic and clinical factors.

Methods

A prospective, multicenter survey study of patients suspected to have cancer based on non-specific symptoms was performed. Participants completed the EORTC-QLQ-C30 quality of life scale, HADS, SOC-13 and self-rated health before and after completing diagnostic evaluations. Intra- and inter-group differences between patients diagnosed with cancer versus patients with non-cancer diagnoses were calculated. The impact of baseline psychological, socio-demographic, and medical factors on HRQoL, anxiety and depression at follow-up was explored by bootstrapped multivariate linear regression analyses and logistic regression analyses.

Results

A total of 838 patients participated in this study; 679 (81 %) completed the follow-up. Twenty-two percent of the patients received a cancer diagnosis at the end of the follow-up. Patients presented initially with a high burden of symptoms and affected role and emotional functioning and global health/QL, irrespective of diagnosis. The prevalence of clinical anxiety prior to knowledge of the diagnosis was 32 % in patients with cancer and 35 % in patients who received a non-cancer diagnosis. HRQoL and anxiety improved after diagnosis, and a larger improvement was seen in patients who received a non-cancer diagnosis. There were no intra- or inter-group differences in the depression scores. The strongest predictors of global QL, anxiety, and depression after a known diagnosis were baseline scores, co-morbidity and poor self-rated health.

Conclusions

Patients undergoing diagnostic evaluations for cancer based on non-specific symptoms experience a high prevalence of anxiety and affected quality of life prior to knowledge of the diagnosis. The predictive value of the baseline scores is important when assessing the psychological impact of undergoing diagnostic evaluations for cancer.

Undergoing Diagnostic Evaluation for Possible Cancer Affects the Health-Related Quality of Life in Patients Presenting with Non-Specific Symptoms

AIM

Undergoing diagnostic evaluation for possible cancer can affect health-related quality of life (HRQoL). The aims of this study were to examine the HRQoL in patients undergoing a diagnostic evaluation for possible cancer due to non-specific symptoms and further to investigate the impact of socio-demographic and medical factors associated with HRQoL at the time of diagnosis.

METHODS

This was a prospective, multicenter survey study that included patients who were referred for a diagnostic evaluation due to non-specific cancer symptoms. Participants completed the EORTC-QLQ-C30 quality of life scale before and after completing the diagnostic evaluation. The baseline and follow-up EORTC-QLQ-C30 scores were compared with reference populations. The impact of socio-demographic and medical factors on HRQoL at follow-up was explored by bootstrapped multivariate linear regression.

RESULTS

A total of 838 patients participated in the study; 680 (81%) also completed follow-up. Twenty-two percent of the patients received a cancer diagnosis at the end of follow-up. Patients presented initially with a high burden of symptoms, less role and emotional functioning and a lower global health/QoL. Most domains improved after diagnosis and no clinically important difference between baseline and follow-up scores was found. Patients reported effects on HRQoL both at baseline and at follow-up compared with the Danish reference population and had similar scores as a cancer reference population. Co-morbidity, being unemployed and receiving a cancer diagnosis had the greatest effect on HRQoL around the time of diagnosis.

CONCLUSIONS

Patients with non-specific symptoms reported an affected HRQoL while undergoing a diagnostic evaluation for possible cancer. Morbidity, being unemployed and receiving a cancer diagnosis had the greatest effect on HRQoL around the time of diagnosis.

Spiritual well-being and quality of life among Icelanders receiving palliative care: data from Icelandic pilot-testing of a provisional measure of spiritual well-being from the European Organisation for Research and Treatment of Cancer

Palliative care focuses on improving quality of life (QoL). This study examined the feasibility of the Icelandic version of a provisional European Organisation for Research and Treatment of Cancer (EORTC) measure of spiritual well-being (SWB), and explored the relationship between SWB and QoL for palliative care patients in Iceland. Instruments from the EORTC were used: the provisional measure of SWB, which was undergoing pilot-testing in Iceland, and the EORTC QLQ C15-PAL. The correlation between scores was examined and descriptive statistics were used. Structured interviews explored feasibility. Thirty persons participated with average age 72 years. Belief in God or a higher power had the mean 3.33 on a 1-4 scale and the mean for overall SWB was 5.73 on a 1-7 scale. The mean score for global health/QoL was 59.4, physical functioning 48.5 and emotional functioning 78.9 on a 0-100 scale. Overall QoL was positively correlated with SWB showing r(30) = 0.386, P = 0.035. The participants found that answering the provisional EORTC QLQ-SWB prompted an emotional response and took the opportunity to discuss the subject. The provisional SWB measure was found relevant for the Icelandic context, and the study indicates that SWB and QoL are closely connected.

A relationship between quality-of-life and head and neck cancer: A systemic review

AIM

The aim was to identify the literature and to assess the association between quality-of-life (QoL) and head and neck cancer (HNC) related outcomes systemically.

MATERIALS AND METHODS

The full articles published in English language bio-medical journals between 1992 and December 2014 were searched using Medline database. The keywords used for searching the articles include the combination of "health-related of QoL," "QoL," "HNC." The search limited only to the observational studies using questionnaires European Organization for Research and Treatment of Cancer (EORTC) QLQ C 30 and EORTC QLQ H and N 35. Purely psychological studies were excluded.

RESULTS

A total of 5055 articles were retrieved, and 16 articles were selected for this review. Of 16 observational studies, 13 (81.25%) were prospective cohort studies while remaining 3 (18.75%) were cross-sectional studies. The main findings of the studies revealed that the treatment of HNC had a statistically significant influence on QoL. Others associated factors like age, female sex, duration of treatment, advance tumor, and site of the tumor has also the impact on QoL on patients suffering from HNC.

CONCLUSION

This review provides evidence for a positive relationship between cancer-related outcomes and QoL. Assessment of QoL in relation to HNC with proper methodology and validated instruments is lacking hence there is a need for further evidence to support the relation between cancer and QoL.

Physical inactivity and risk of poor quality of life among elderly cancer survivors compared to women without cancer: the Iowa Women's Health Study

PURPOSE

Few studies have examined lifestyle factors and quality of life (QOL) in cancer survivors compared to a cancer-free group. Compared to active cancer-free women, we examined the association between physical inactivity and QOL in elderly cancer survivors and similar-aged women without cancer.

METHODS

Participants included 1776 cancer survivors and 12,599 cancer-free women enrolled in the Iowa Women's Health Study in 1986 who completed the SF36 QOL assessment in 2004 (ages 73-88 years). The odds of poor QOL were computed for each SF36 subscale (>0.5 SD below mean score of cancer-free women) associated with physical inactivity (moderate-vigorous activity <once/week) between four groups based on the cross-classification of cancer history (no/yes) and physical inactivity (no/yes) (referent group = active cancer-free women).

RESULTS

Compared with the referent group, inactive cancer survivors were significantly more likely to report poor QOL for each SF36 subscale (odds ratios 1.8 to 4.7), independent of age, comorbidity, body mass index (BMI), and diet quality. The greatest odds for poor QOL occurred for general health, vitality, and physical function. These increased odds occurred regardless of whether survivors were inactive at both baseline (1986) and follow-up or became inactive sometime after baseline. Among physically active women, cancer survivors had similar QOL as cancer-free women.

CONCLUSION

These findings provide evidence on the importance of leisure-time physical activity in older women and support the need for interventions to help older women maintain or regain a physically active lifestyle.

IMPLICATIONS FOR CANCER SURVIVORS

Survivors who remain or become physically active as they age report better mental and physical QOL.

Quality of life among prostate cancer patients: a prospective longitudinal population-based study

PURPOSE

To investigate the course of quality of life (QoL) among prostate cancer patients treated with external beam radiotherapy and to compare the results with QoL of a normal age-matched reference population.

PATIENTS AND METHODS

The study population was composed of 227 prostate cancer patients, treated with radiotherapy. The EORTC QLQ-C30 was used to assess QoL before radiotherapy and six months, one year, two years and three years after completion of radiotherapy. Mixed model analyses were used to investigate longitudinal changes in QoL. QoL of prostate cancer patients was compared to that of a normative cohort using a multivariate analysis of covariance.

RESULTS

A significant decline in QoL was observed after radiotherapy (p<0.001). The addition of hormonal therapy to radiotherapy was associated with a lower level of role functioning. Patients with coronary heart disease and or chronic obstructive pulmonary disease or asthma had a significantly worse course in QoL. Although statistically significant, all differences were classified as small or trivial.

CONCLUSION

Prostate cancer patients experience a small worsening of QoL as compared with baseline and as compared with a normal reference population. As co-morbidity modulates patients' post-treatment QoL, a proper assessment of co-morbidity should be included in future longitudinal analyses on QoL.

Depression and anxiety in long-term cancer survivors compared with spouses and healthy controls: a systematic review and meta-analysis

BACKGROUND

Cancer survival has improved in the past 20 years, affecting the long-term risk of mood disorders. We assessed whether depression and anxiety are more common in long-term survivors of cancer compared with their spouses and with healthy controls.

METHODS

We systematically searched Medline, PsycINFO, Embase, Science Direct, Ingenta Select, Ovid, and Wiley Interscience for reports about the prevalence of mood disorders in patients diagnosed with cancer at least 2 years previously. We also searched the records of the International Psycho-oncology Society and for reports that cited relevant references. Three investigators independently extracted primary data. We did a random-effects meta-analysis of the prevalences of depression and anxiety in cancer patients compared with spouses and healthy controls.

FINDINGS

Our search returned 144 results, 43 were included in the main analysis: for comparisons with healthy controls, 16 assessed depression and ten assessed anxiety; of the comparisons with spouses, 12 assessed depression and five assessed anxiety. The prevalence of depression was 11·6% (95% CI 7·7-16·2) in the pooled sample of 51 381 cancer survivors and 10·2% (8·0-12·6) in 217 630 healthy controls (pooled relative risk [RR] 1·11, 95% CI 0·96-1·27; p=0·17). The prevalence of anxiety was 17·9% (95% CI 12·8-23·6) in 48 964 cancer survivors and 13·9% (9·8-18·5) in 226 467 healthy controls (RR 1·27, 95% CI 1·08-1·50; p=0·0039). Neither the prevalence of depression (26·7% vs 26·3%; RR 1·01, 95% CI 0·86-1·20; p=0·88) nor the prevalence of anxiety (28·0% vs 40·1%; RR 0·71, 95% CI 0·44-1·14; p=0·16) differed significantly between cancer patients and their spouses.

INTERPRETATION

Our findings suggest that anxiety, rather than depression, is most likely to be a problem in long-term cancer survivors and spouses compared with healthy controls. Efforts should be made to improve recognition and treatment of anxiety in long-term cancer survivors and their spouses.

Determinants of quality of life in advanced cancer patients with bone metastases undergoing palliative radiation treatment

PURPOSE

Assessment of health-related quality of life (HRQOL) is critical to effective delivery of palliative care in patients with advanced cancer. The current study analyzes relationships between baseline social determinants of health and medical factors, and self-reported HRQOL in patients with bone metastases receiving palliative radiotherapy.

METHODS AND MATERIALS

Advanced cancer patients referred for radiotherapy treatment of bone metastases completed the EORTC QLQ-C30 questionnaire in multiple outpatient clinics internationally. Demographics and social determinants were collected as baseline information. Univariate and Bonferroni-adjusted multivariate linear regression analyses were used to detect significant correlations between baseline determinants and different HRQOL domains.

RESULTS

Karnofsky Performance Status (KPS) was correlated with better physical (p = 0.0002), role (p < 0.0001), emotional (p < 0.0001), and social (p < 0.0001) functioning, and global health scores (p = 0.0015) and predicted lower symptom scores for fatigue (p < 0.0001), pain (p < 0.0001), appetite loss (p < 0.0001), and constipation (p < 0.0001). Increased age was predictive of better social functioning (p < 0.0001) and less insomnia (p = 0.0036), higher education correlated with better global health status (p = 0.0043), and patients who were employed or retired had improved physical functioning (p = 0.0004 and p = 0.0030, respectively) and less financial challenges compared to patients who were unemployed (p = 0.0005).

CONCLUSIONS

Baseline KPS had the greatest influence on EORTC QLQ-C30 domain scores. Age, education level, and employment status had significant impacts, although on fewer domains. Further studies that investigate baseline determinants are worthwhile to clarify relationships in order to care for patients more effectively at the end of life.

One-year course of fatigue after post-operative radiotherapy in Norwegian breast cancer patients--comparison to general population

INTRODUCTION

Fatigue after treatment for breast cancer (BC) is common, but poorly understood. We examined the fatigue levels during first year after radiotherapy (RT) according to the extent of RT (local or locoregional), hormonal therapy (HT) and chemotherapy (CT). The impact of comorbidity was also explored. Moreover, we compared fatigue levels in patients with the general population (GenPop) data.

MATERIAL AND METHODS

BC patients (n = 250) referred for post-operative RT at St. Olavs Hospital, Trondheim, Norway, were enrolled. Fatigue was measured by the EORTC QLQ-C30-fatigue subscale, ranging from 0 to 100, before RT (baseline), after RT, and at three, six, and 12 months. Clinical and treatment-related factors were recorded at baseline. GenPop data was available from a previous survey (n = 652). Linear mixed models and analysis of covariance were applied.

RESULTS

Compliance ranged from 87% to 98%. At baseline, mean value (SD) of fatigue in BC patients was 26.8 (23.4). The level increased during RT (mean change 8.3, 95% CI 5.5-11.1), but declined thereafter and did not differ significantly from pre-treatment levels at subsequent time points. In age-adjusted analyses, locoregional RT accounted for more overall fatigue than local RT (mean difference 6.6, 95% CI 1.2-12.0), but the association was weakened and not statistical significant when adjusting for CT and HT. Similar pattern was seen for CT and HT. The course of fatigue differed significantly by CT (p < 0.001, interaction test). At baseline, fatigue levels were higher in patients with than without CT, but at subsequent time points similar levels were evident, indicating a temporary adverse effect of CT. Comorbidity was significantly associated with increased level of fatigue, independent of other factors (mean difference 8.1, 95% CI 2.2-14.1). BC-patients were not significantly more fatigued than GenPop, except for immediately after ending RT, and then only among those without comorbidity (mean 35.9 vs. 25.8, p < 0.001).

CONCLUSION

Comorbidity seems to be a more important determinant for fatigue levels than the cancer treatment.

All's well that ends well? Quality of life and physical symptom clusters in long-term cancer survivors across cancer types

CONTEXT

Little is known about the presentation of multiple concurrent symptoms (symptom clusters) in long-term cancer survivors, with few studies adequately powered to compare quality of life (QoL) and symptom presentation by cancer type.

OBJECTIVES

This research aimed to 1) assess patient-reported QoL and 2) identify clusters of cancer-related physical symptoms by cancer type among long-term breast, prostate, colorectal, and melanoma cancer survivors.

METHODS

A population-based cross-sectional sample of 863 adult cancer survivors five to six years post-diagnosis completed the European Organization for Research and Treatment of Cancer Quality of Life Questionnaire (EORTC QLQ-C30), assessing global QoL and frequency of presentation of cancer-related physical symptoms.

RESULTS

Long-term survivors reported higher levels of global QoL than 1) the general population (age-adjusted mean=79.4 vs. 71.1, small clinical difference) and 2) cancer patients early in the care trajectory (age-adjusted mean=77.1 vs. 61.3, moderate clinical difference). The majority (71%) did not report any cancer-related physical symptoms; 18% reported multiple (two or more) symptoms in the past month. Factor analysis found that cognitive functioning, fatigue, insomnia, pain, dyspnea, appetite loss, constipation, diarrhea, nausea, and vomiting formed a cluster (α=0.48). No symptom clusters were identified that were specific to just one cancer type. However, individual symptoms (including diarrhea, pain, constipation, and insomnia) modestly discriminated between cancer types.

CONCLUSION

Contrary to expectations, no symptom clusters specific to one type of cancer were identified and survivors reported few cancer-related symptoms and high QoL. These results convey a strong "good news" message, providing health professionals with a sound foundation for making encouraging predictions about their patients' long-term physical recovery after cancer. Cancer patients also will welcome the news that only a minority of five-year survivors experience long-term and late effects.

Quality of life following liver transplantation in patients with liver metastases from colorectal carcinoma

PURPOSE

To study quality of life (QoL) in patients with liver metastases from colorectal carcinoma (CRC) following liver transplantation (Ltx).

METHODS

Ten patients participated in a prospective explorative pilot study. Inclusion criteria were nonresectable liver-only metastases determined by CT/MRI-, PET/CT- scans and colonoscopy, and ECOG 0-1. Primary outcome was QoL assessed by the EORTC-C30 questionnaires at baseline, and at 3, 6 and 12 months after Ltx.

RESULTS

The patients' age ranged from 50 to 63 years. Nine of 10 patients were observed for 12 months. One patient did not return the form at 6 months and died shortly after because of recurrence of the malignant disease. Compared to baseline, Ltx resulted in sustained excellent global health status scale (score of 100) in one patient, improved scores in 4 and unchanged scores in 3 patients at 12 months. The majority of the patients also reported good functional scores at follow-ups. Although two patients had marked symptoms both before and after Ltx, the patients in general reported low levels of pain and fatigue before and after surgery.

CONCLUSION

The present study indicates that CRC patients with liver-only metastases who receive Ltx have good QoL and have mostly minor symptoms the first year after Ltx.

Quality of life in chronic lymphocytic leukemia: 5-year results from the multicenter randomized LRF CLL4 trial

Health-related quality of life (HRQoL) is a key issue for patients with chronic lymphocytic leukemia. The multicenter LRF CLL4 trial, in which 777 patients were randomized to receive chlorambucil or fludarabine, alone or with cyclophosphamide (FC), assessed HRQoL at baseline, months 3, 6 and 12, then annually until 5 years, using the European Organisation for Research and Treatment of Cancer quality of life questionnaire (EORTC-QLQ-C30). While on treatment, some HRQoL impairment was seen in patients receiving fludarabine, particularly FC, compared with chlorambucil. Thus at 3 months, role/social functioning and fatigue were ≥ 10 points worse than baseline in 41%/46%/56%, respectively, of patients receiving fludarabine alone and 48%/54%/60% receiving FC, compared with only 29%/31%/40% of those receiving chlorambucil. Thereafter HRQoL appeared similar between treatment groups. Sustained remissions were associated with long-term HRQoL benefit. In the primary HRQoL domains patients still in complete or partial remission at each time-point had scores close to those reported in general population studies, while patients whose disease had progressed had mean scores up to 22 points worse, in spite of subsequent treatments. These data offer support for the use of primary treatment regimens likely to achieve and sustain remission in otherwise medically fit patients of all ages, including those aged > 70 years.

Health-Related Quality of Life During the 10 Years After Diagnosis of Colorectal Cancer: A Population-Based Study

Purpose

To compare long-term quality of life (QoL) of colorectal cancer survivors with QoL in the general population and investigate changes in QoL of survivors during the 10 years after diagnosis.

Patients and Methods

Health-related QoL was assessed 1, 3, 5, and 10 years after diagnosis in a population-based cohort starting with 439 patients with colorectal cancer from Saarland, Germany, using the European Organisation for Research and Treatment of Cancer Quality of Life Questionnaire Core 30. QoL after 5 and 10 years and time course of QoL during the 10 years after diagnosis were compared with controls from the general population of Germany, after controlling for sex and age.

Results

Overall, 234 and 196 patients were still alive after 5 and 10 years, respectively. Of these survivors, 178 (76%) responded in the 5-year follow-up, 133 (68%) in the 10-year follow-up, and 117 (60%) participated in all follow-ups. Over the entire follow-up, younger survivors (age at diagnosis, < 60 years) reported restrictions in role, social, emotional, and cognitive functioning and specific problems like constipation, diarrhea, fatigue, and insomnia. Older survivors (age at diagnosis, ≥ 70 years) reported comparable or even better QoL than controls within the first 3 to 5 years after diagnosis and comparable to worse QoL 5 to 10 years after diagnosis.

Conclusion

Although younger survivors continuously reported detriments in various QoL dimensions during the 10-year period after diagnosis, detriments in older survivors became apparent in the long run only.

Adult survivors of childhood malignant lymphoma are not aware of their risk of late effects

PURPOSE

Survivors after malignant lymphoma are at high risk of late effects. In order to take full responsibility for their own health they need knowledge about their diagnosis, treatment and risk of late effects. We assessed such knowledge in adult survivors of childhood malignant lymphoma.

MATERIAL AND METHODS

In 2007-2009 128 five-year survivors after childhood malignant lymphoma participated in a national cross-sectional questionnaire-based survey combined with clinical examination. [Males: 69, females: 59, treatment period 1970-2000, median age (range) at diagnosis: 14 years (0-18), at survey: 32 years (19-55), Hodgkin lymphoma (HL): 84, Non-Hodgkin lymphoma (NHL): 44]. Prior to the clinical examination a semi-structured interview on the survivors' knowledge was conducted by a study nurse. The individual survivors' responses were compared with his/her medical record.

RESULTS

One hundred and twenty one reported their diagnosis correctly, seven reported that they had cancer, but could not specify malignant lymphoma. Thirty-three could not differentiate between HL and NHL. One hundred and twenty three reported their treatment modalities correctly (radiotherapy vs. chemotherapy vs. combined). Eighty-five (66%) were not aware of any risks for late effects. The remaining 43 listed at least one of the following late effects; infertility, heart-problems, impaired dental status, hypothyroidism, breast cancer, reduced muscle growth, fatigue and reduced memory or concentration. Thirty-seven survivors who provided additional comments reported that they had received some information about risk of late effects from their therapists. Age at diagnosis or educational level were not associated with knowledge about possible late effects while treatment period was.

CONCLUSIONS

Norwegian long-term survivors of childhood malignant lymphomas are showing improved level of knowledge of their diagnosis and treatment modalities during the last decade. Still, independent of age at diagnosis and level of education, they are insufficiently aware of their risk of late effects.

Normative data for the EORTC QLQ-C30 and EORTC-sexuality items in the general Dutch population

AIM

The aim of the present study was to generate Dutch reference data for the EORTC QLQ-C30 and for five sexuality items from the EORTC QL-item bank. Furthermore, to evaluate the relative impact of self-reported health problems on these outcomes and compare the Dutch normative EORTC QLQ-C30 overall QoL with available Scandinavian and German normative data.

METHODS

QLQ-C30 and sexual item normative data were obtained from the Health and Health Complaints project from CentERdata. The CentERpanel is an online household panel consisting of more than 2000 Dutch households, representative of the Dutch-speaking population in the Netherlands.

RESULTS

The questionnaire was completed by 1731 (78%) CentERpanel members. For both men and women, functional health (except emotional functioning) decreased with age, and the symptoms pain and fatigue increased with age. Men scored statistically but never clinically significantly better on most functional scales than women. Men reported higher levels of sexual interest and activity than women. All subgroups of participants with health problems reported lower physical and role functioning and overall quality of life (QoL). Those with depression (n=79) reported functioning scores 20-30 points lower than participants without any condition. Dutch men and women reported high levels of overall QoL as compared to previously published Scandinavian and German normative data.

CONCLUSION

Age, gender and other health problems are important when comparing QoL and sexuality among different cancer cohorts. Normative data on QoL and sexuality are needed to interpret QoL issues among the growing group of (long-term) cancer survivors.

Changes in arm morbidities and health-related quality of life after breast cancer surgery - a five-year follow-up study

BACKGROUND AND PURPOSE. Many breast cancer survivors (BCS) suffer from long-term upper limb morbidities after axillary node dissection. The purpose of this five-year follow-up study was to describe changes in long-term upper limb morbidities, physical activity level, and Health-Related Quality of Life (HRQoL) and to find factors that predict HRQoL five years after surgery. PATIENTS AND METHODS. This study included 204 women aged 55+/-10 years who had primary breast cancer surgery with axillary node dissection. The subjects were examined for arm volumes and arm lymphedema, arm pain, sensation of heaviness, shoulder function, physical activity level, and HRQoL, prior to surgery, and six months and five years after surgery. The statistical analyses used included ANOVA for repeated measures and multivariate linear regression. RESULTS. ALE (13%), pain (36%), and sensation of heaviness (21%) in the upper limbs were present five years after surgery. ALE was the only morbidity that continued to increase over time. Several dimensions of HRQoL temporarily declined after surgery, but significantly improved in the period from six months to five years after surgery. The significant predictive factors of HRQoL five years after surgery included HRQoL prior to surgery, physical activity level at leisure time (both prior to and at six months after surgery), and duration of sick leave after surgery (in weeks). CONCLUSIONS. The overall HRQoL improved significantly from baseline to five years, despite the chronic arm pain and increase in ALE. Three independent predictive factors of HRQoL were identified.
