Quality-of-life measurement in randomized clinical trials in breast cancer: an updated systematic review (2001-2009)

Accelerated versus standard epirubicin followed by cyclophosphamide, methotrexate, and fluorouracil or capecitabine as adjuvant therapy for breast cancer (UK TACT2; CRUK/05/19): quality of life results from a multicentre, phase 3, open-label, randomised, controlled trial

BACKGROUND

Adjuvant chemotherapy for patients with early breast cancer improves outcomes but its toxicity affects patients' quality of life (QOL). The UK TACT2 trial investigated whether accelerated epirubicin improves time to recurrence and if oral capecitabine is non-inferior to cyclophosphamide, methotrexate, and fluorouracil (CMF) for efficacy with less toxicity. Results showed no benefit for accelerated epirubicin and capecitabine was non-inferior. As part of the QOL substudy, we aimed to assess the effect of chemotherapies on psychological distress, physical symptoms, and functional domains.

METHODS

TACT2 was a multicentre, phase 3, open-label, parallel-group, randomised, controlled trial done in 129 UK centres. Participants were aged 18 years or older with histologically confirmed node-positive or high-risk node-negative invasive primary breast cancer, who had undergone complete excision, and due to receive adjuvant chemotherapy. Patients were randomly assigned (1:1:1:1) to four cycles of 100 mg/m2 epirubicin either every 3 weeks (standard epirubicin) or every 2 weeks with 6 mg pegfilgrastim on day 2 of each cycle (accelerated epirubicin), followed by four 4-week cycles of either CMF (600 mg/m2 cyclophosphamide intravenously on days 1 and 8 or 100 mg/m2 orally on days 1-14; 40 mg/m2 methotrexate intravenously on days 1 and 8; and 600 mg/m2 fluorouracil intravenously on days 1 and 8 of each cycle) or four 3-week cycles of 2500 mg/m2 capecitabine (1250 mg/m2 given twice daily on days 1-14 of each cycle). The randomisation schedule was computer generated in random permuted blocks, stratified by centre, number of nodes involved (none vs 1-3 vs ≥4), age (≤50 years vs >50 years), and planned endocrine treatment (yes vs no). QOL was one of the secondary outcomes and is reported here. All patients from a subset of 44 centres were invited to complete QOL questionnaires (Hospital Anxiety and Depression Scale [HADS] and European Organisation for Research and Treatment of Cancer [EORTC] Quality of Life Questionnaire 30-item core module [QLQ-C30] and Quality of Life Questionnaire breast module [QLQ-BR23]) at baseline, end of standard or accelerated epirubicin, end of CMF or capecitabine, and at 12 and 24 months after randomisation. The QOL substudy prespecified two coprimary QOL outcomes assessed in the intention-to-treat population: overall QOL (reported elsewhere) and HADS total score. Prespecified secondary QOL outcomes were EORTC QLQ-C30 subscales of physical function, role function, and fatigue and EORTC QLQ-BR23 subscales of sexual function and systemic therapy side-effects. This trial is registered with ISRCTN, ISRCTN68068041, and ClinicalTrials.gov, NCT00301925.

FINDINGS

From Dec 16, 2005, to Dec 5, 2008, 4391 patients (20 [0·5%] of whom were male) were enrolled in TACT2; 1281 (85·8%) of 1493 eligible patients were included in the QOL substudy. Eight (0·6%) participants in the QOL substudy were male and 1273 (99·4%) were female. Median follow-up was 85·6 months (IQR 80·6-95·9). Analysis was performed on the complete QOL dataset (as of Sept 15, 2011) when all participants had passed the 24-month timepoint. Prerandomisation questionnaires were completed by 1172 (91·5%) patients and 1179 (92·0%) completed at least one postrandomisation questionnaire. End-of-treatment HADS depression score (p=0·0048) and HADS total change score (p=0·0093) were worse for CMF versus capecitabine. Accelerated epirubicin led to worse physical function (p=0·0065), role function (p<0·0001), fatigue (p=0·0002), and systemic side-effects (p=0·0001), but not sexual function (p=0·36), compared with standard epirubicin during treatment, but the effect did not persist. Worse physical function (p=0·0048), sexual function (p=0·0053), fatigue (p<0·0001), and systemic side-effects (p<0·0001), but not role functioning (p=0·013), were seen for CMF versus capecitabine at end of treatment; these differences persisted at 12 months and 24 months.

INTERPRETATION

Accelerated epirubicin was associated with worse QOL than was standard epirubicin but only during treatment. These findings will help patients and clinicians make an informed choice about accelerated chemotherapy. CMF had worse QOL effects than did capecitabine, which were persistent for 24 months. The favourable capecitabine QOL compared with CMF supports its use as an adjuvant option after neoadjuvant chemotherapy in patients with triple-negative breast cancer.

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.

Health-related quality of life in Her2-positive early breast cancer woman using trastuzumab: A systematic review and meta-analysis

Background: Despite the benefits of trastuzumab in many trials, evidence of its impact on health-related quality of life (HRQoL) in early treatment has not been summarized. This study explored the effects of trastuzumab treatment on HRQoL, including pooled meta-analysis, in an effort to provide an integrated assessment of HRQoL for Her2-positive early breast cancer patients. Methods: A comprehensive literature review to February 2023 using three databases, focusing on treatment using trastuzumab during the early stage, was performed. The mean changes from baseline during and after treatment were extracted from the included randomized control trials (RCTs) papers and total HRQoL scores were obtained from cross-sectional studies included. Mean difference (MD) and 95% confidence intervals were assessed by a random effect or fixed effect model based on heterogeneity (I²). Results: A total of ten studies were identified and reviewed, consisting of seven RCTs and three cross-sectional studies. The pooled analysis of the mean change from baseline during treatment resulted in an MD of 1.92 (95% CI = 1.59 to 2.25, p < 0.05, I² = 0%), favoring the trastuzumab group. A non-significant result of the mean change from baseline after treatment appeared in the analysis of 12-month follow-up. In the cross-sectional studies, pooled analyses of HRQoL showed that trastuzumab meaningfully demonstrated an improved HRQoL profile (MD = 9.29, 95% CI = 1.31 to 17.27, p = 0.02, I² = 0%). Conclusion: Trastuzumab as a targeted therapy resulted in a favorable effect on HRQoL in the early stages of Her2-positive breast cancer. The findings of significant improvements in patients' HRQoL and less clinically meaningful deterioration in side effects of trastuzumab-containing regimen during treatment were supported by prolonged survival.

Quality of Life in Breast Cancer Survivors in Relation to Age, Type of Surgery and Length of Time since First Treatment

(1) Background: Quality of life assessment is a critical aspect of breast cancer patient outcomes, as diagnosis, prognosis and treatment can have a major impact on quality of life. The aim of this study was to describe the characteristics of the sample and to verify the relationship between quality of life (QOL) in women diagnosed with breast cancer (BC) and their age, type or surgery and time since treatment; (2) Methods: a cross-sectional, descriptive study was conducted with 183 women diagnosed with BC, aged 30−80 years in Mexico. Women’s QOL was assessed using two questionnaires, The European Organization for Research and Treatment of Cancer-Quality of Life Core Questionnaire (EORTC QLQ-C30) and The Breast Cancer Module (EORTC QLQ-BR23). (3) Results: the results show significant differences in several items when the variable age is taken into account, indicating that younger women have poorer social and sexual function, as well as poorer sexual enjoyment and lower expectations of the future. The type of surgery also indicates a significantly better QOL in those women who receive conservative treatment versus a mastectomy; the time elapsed since surgery does not show any significant results, except for sexual functioning and breast-related symptoms where >5 years implies better scores on the items. (4) Conclusions: in conclusion, it is important to take into account the characteristics of women with BC, particularly at the time of treatment, in order to mitigate the impact of the disease on their QOL with the help of a multidisciplinary team.

The effectiveness of case management for cancer patients: an umbrella review

Background

Case management (CM) is widely utilized to improve health outcomes of cancer patients, enhance their experience of health care, and reduce the cost of care. While numbers of systematic reviews are available on the effectiveness of CM for cancer patients, they often arrive at discordant conclusions that may confuse or mislead the future case management development for cancer patients and relevant policy making. We aimed to summarize the existing systematic reviews on the effectiveness of CM in health-related outcomes and health care utilization outcomes for cancer patient care, and highlight the consistent and contradictory findings.

Methods

An umbrella review was conducted followed the Joanna Briggs Institute (JBI) Umbrella Review methodology. We searched MEDLINE (Ovid), EMBASE (Ovid), PsycINFO, CINAHL, and Scopus for reviews published up to July 8th, 2022. Quality of each review was appraised with the JBI Critical Appraisal Checklist for Systematic Reviews and Research Syntheses. A narrative synthesis was performed, the corrected covered area was calculated as a measure of overlap for the primary studies in each review. The results were reported followed the Preferred reporting items for overviews of systematic reviews checklist.

Results

Eight systematic reviews were included. Average quality of the reviews was high. Overall, primary studies had a slight overlap across the eight reviews (corrected covered area = 4.5%). No universal tools were used to measure the effect of CM on each outcome. Summarized results revealed that CM were more likely to improve symptom management, cognitive function, hospital (re)admission, treatment received compliance, and provision of timely treatment for cancer patients. Overall equivocal effect was reported on cancer patients’ quality of life, self-efficacy, survivor status, and satisfaction. Rare significant effect was reported on cost and length of stay.

Conclusions

CM showed mixed effects in cancer patient care. Future research should use standard guidelines to clearly describe details of CM intervention and its implementation. More primary studies are needed using high-quality well-powered designs to provide solid evidence on the effectiveness of CM. Case managers should consider applying validated and reliable tools to evaluate effect of CM in multifaced outcomes of cancer patient care.

Adaptability and clinical applicability of UFS-QoL in Chinese women with uterine fibroid

Objective

To demonstrate the applicability and adaptability of uterine fibroid symptoms and quality of life (UFS-QoL) in assessing the efficacy of treatment in Chinese populations.

Methods

This is a secondary analysis of a prospective cohort study involving 20 Chinese hospitals and 2,411 Chinese women with fibroids. Patients completed UFS-QoL and short form-36 (SF-36) at pre-surgery, 6-month and 12-month post-treatments. Internal consistency of the quality of life assessed by the UFS-QoL questionnaire using Cronbach’s α coefficient (α). Principal axis factor analysis with orthogonal rotation was established to investigate relationships between items and subscales. Concurrent validity refers to the Spearman's correlation estimate of the correlation between UFS-QoL and SF-36. Using effect size and standardized response mean, the ability to detect change was evaluated by comparing pre- and post-6-month and post-12-month treatment scores.

Results

Exploratory factor analysis yielded six subscales (concern, activities, energy/mood, control, self-consciousness, and sexual function) with eigenvalues > 1 in UFS-QoL. A 63.61% total variance was explained by the test items. Ceiling effects of self-consciousness and sexual functioning subscales from UFS-QoL were > 15%. UFS-QoL showed a positive and moderate correlation with SF-36 to establish good concurrent validity. And showed good consistency reliability (Cronbach α > 0.7 in all subscales), ability to detect change after treatment. This excluded self-consciousness (α = 0.56), which demonstrated the lowest effect size (0.38) and standardized response means (0.38) 6- and 12-months post-treatment.

Conclusions

Symptom severity, activity, and mood subscales of the Chinese UFS-QoL were valid and reliable. However, the self-consciousness domain needs further investigation on cultural adaptation, such as cognitive debriefing for how Chinese interpret these questions.

Quality of Life in Early Breast Cancer Patients: A Prospective Observational Study Using the FACT-B Questionnaire

BACKGROUND/AIM

Quality of life (QoL) in early breast cancer (BC) treatment may be affected by acute and late toxicities. This study evaluated the impact of radiotherapy (RT) schedules, treatment-related toxicities, hormone therapy (HT) and age on QoL.

PATIENTS AND METHODS

Ninety-five patients answered the FACT-B 4.0 questionnaire. Acute or late toxicities were recorded at each follow-up visit.

RESULTS

The median trend of the QoL subscales was stable during all questionnaires. HT negatively impacted on Functional Assessment of Cancer Therapy-General-Total, functional and emotional wellbeing. No difference was recorded between RT schedules and toxicity. No significant differences for age were detected in QoL.

CONCLUSION

RT seems not to influence QoL of BC patients, in terms of fractionation regimen or RT-related side-effects. Moreover, women having systemic HT experienced a QoL worse than patients treated with RT only. Further and long-term protocols are needed to improve the validity of the tool.

Health-related quality of life in breast cancer patients: review of reviews from 2008 to 2018

BACKGROUND

Breast cancer still is a topic. This overview of the literature aimed to update the current knowledge on quality of life in breast cancer patients.

METHODS

A review of literature in MEDLINE, Cochrane Database of Systematic Reviews and Google Scholar were carried out to identify review papers on health-related quality of life in breast cancer during the 2008 to 2018. All publications were screened using the PRISMA guideline. The methodological quality of reviews was assessed using the AMSTAR. The findings were summarized and tabulated accordingly.

RESULTS

Within over a decade, a total of 974 review papers were identified which according to the study selection criteria finally we have evaluated 82 reviews. Of these about 85% had a reasonable methodological quality. The findings were mainly summarized on several headings including instruments used to measure quality of life, treatment, supportive care, psychological distress, and symptoms. Questionnaires had a good performance to quantify quality of life in breast cancer patients. Most reviews were focused on the impact of treatment including endocrine therapy as well as integrating complementary and alternative medicine into the current practice. According to the reviews, yoga was the most recommended exercise to improve quality of life in breast cancer patients.

CONCLUSION

Overall, the findings from this overview indicated that quality of life in breast cancer patients enhanced during the last decade. Several simple but effective interventions such as physical activity and psychosocial interventions proved to be effective in improving quality of life in this population. However, management of symptoms such as pain, and lymphedema, issues related to worry, sexual function especially for young patients, and the future outlooks all are among topics that deserve further consideration. Also, this overview indicated that methodological issues in measuring quality of life in breast cancer patients improved greatly, but still there is a long way to go to understand what really matter to patients.

Assessment of Quality of Life in Postmenopausal Women with Early Breast Cancer Participating in the PACT Trial: The Impact of Additional Patient Information Material Packages and Patient Compliance

Background

Breast cancer patients' self-understanding of their disease can impact their quality of life (QoL); the relationship between compliance and QoL is poorly understood.

Patients and Methods

The Patient's Anastrozole Compliance to Therapy (PACT) program, a prospective, randomized study, investigated the effect of additional patient information material (IM) packages on compliance with adjuvant aromatase inhibitor (AI) therapy in postmenopausal women with hormone receptor-positive early breast cancer. The QoL subanalysis presented here examined the impact of IM packages on QoL and the association between QoL and compliance. European Organization for Research and Treatment of Cancer (EORTC) QLQ-C30 and QLQ-BR23 questionnaires were completed at baseline, 12 and 24 months, or study termination to assess health-related QoL and disease-related symptoms.

Results

Of the 4,844 patients randomized to standard therapy or standard therapy + IM packages (1:1), 4,253 were available for QoL analysis. No difference in QoL was observed between groups at baseline. IM packages did not have a statistically significant impact on patient QoL at the 12- or 24-month follow-up. Compliant patients experienced improvement in multiple items across the QLQ-C30 and QLQ-BR23 scales at 12 months. However, those results should be interpreted carefully due to limitations in the statistical analyses.

Conclusions

Provision of IM packages did not influence patients' QoL or satisfaction with care during AI therapy. Compliant patients appear to experience improved QoL compared to noncompliant patients, perhaps indicating a more self-empowered perception of their condition.

Using time series analysis to forecast the health-related quality of life of post-menopausal women with non-metastatic ER+ breast cancer: A tutorial and case study

BACKGROUND

Time series models are widely used forecasting techniques in health care for long time series and are typically built in commercial statistical packages. However, for short time series data, such as health-related quality of life (HRQoL), guidance on how to select and use appropriate time series models is lacking. This tutorial provides a step-by-step guide adopting a time series analysis framework for HRQoL forecasting.

OBJECTIVE

We walk through a case study examining the forecasting of the effects of adjuvant endocrine therapy on the HRQoL of post-menopausal women with non-metastatic ER + breast cancer using data from the HRQoL sub-protocol of the Tamoxifen arm of the Arimidex, tamoxifen, alone or in combination (ATAC) trial.

METHODS

The forecasting of HRQoL consists of four steps: 1) data extraction and accuracy check, 2) forecasting horizon definition and identification of data pattern, 3) forecasting model identification and fitting using five forecasting approaches appropriate for short time series ((i) double exponential smoothing, (ii) double moving average, (iii) fuzzy forecasting, (iv) grey forecasting, and (v) Volterra series), 4) forecasting model selection. A user-friendly visual basic for applications (VBA) Excel add-in is made available to interested users to facilitate the application of the tutorial.

RESULTS

The Grey method and Volterra series appeared to be good candidates to forecast the effects of adjuvant endocrine therapy on the HRQoL of post-menopausal women with non-metastatic ER + breast cancer enrolled in the ATAC trial.

CONCLUSION

It is feasible to forecast the effects of treatments on HRQOL even when the time series is short.

The added value of geriatric assessment in evaluating a patient's Health-Related Quality-of-Life: A study in ≥70-year-old early-stage invasive breast cancer patients

OBJECTIVE

The objective of this study was to assess the relationship between geriatric assessment (GA) and health-related Quality-of-Life (HRQOL) in older patients with breast cancer.

METHODS

Patients were assigned either to adjuvant chemotherapy (CTG) or to a control group (CG). Spearman rank coefficients (ρ) calculated correlations between HRQOL and GA at baseline, 3 months and 1 year. Multivariate regressions modelled the prognostic value of GA in evaluating of a patient's HRQOL and the accuracy of baseline GA in predicting HRQOL decline (change of ≥10 points).

RESULTS

The analysis included 57 patients in the CTG and 52 in the CG. Strong correlations (ρ ≥ 0.5) were reported between the EORTC QLQ-C30 Physical Functioning Scale and Activities of Daily Living (ADL), Instrumental ADL (iADL) and Leuven Oncogeriatric Frailty Score Scale (LOFS). Multivariate models demonstrated that poor iADL, ADL and LOFS (CG) and ADL and iADL (CTG) contributed to a statistically (all p < .05) worse HRQOL. The relative gain in predicting 3-month and 1-year HRQOL decline was 24.1% and 4.7% (CG) and 6.1% and 18.3% (CTG).

CONCLUSION

Our results show that the functional measures in the GA are strongly correlated with patient self-reported functioning. Poor baseline GA has a modest probability of predicting HRQOL deterioration.

Congruence of patient- and clinician-reported toxicity in women receiving chemotherapy for early breast cancer

BACKGROUND

The National Cancer Institute's Patient-Reported Outcomes Version of the Common Terminology Criteria for Adverse Events, collected alongside the clinician-reported Common Terminology Criteria for Adverse Events, enables comparisons of patient and clinician reports on treatment toxicity.

METHODS

In a multisite study of women receiving chemotherapy for early-stage breast cancer, symptom reports were collected on the same day from patients and their clinicians for 17 symptoms; their data were not shared with each other. The proportions of moderate, severe, or very severe patient-reported symptom severity were compared with the proportions of clinician-rated grade 2, 3, or 4 toxicity. Patient-clinician agreement was assessed via κ statistics. Chi-square tests investigated whether patient characteristics were associated with patient-clinician agreement.

RESULTS

Among 267 women, the median age was 58 years (range, 24-83 years), and 26% were nonwhite. There was moderate scoring agreement (κ = 0.413-0.570) for 53% of symptoms, fair agreement for 41% (κ = 0.220-0.378), and slight agreement for 6% (κ = 0.188). For example, patient-reported and clinician-rated percentages were 22% and 8% for severe or very severe fatigue, 41% and 46% for moderate fatigue, 32% and 39% for mild fatigue, and 6% and 7% for none. Clinician severity scores were lower for nonwhite patients in comparison with white patients for peripheral neuropathy, nausea, arthralgia, and dyspnea.

CONCLUSIONS

Although clinician reporting of symptoms is common practice in oncology, there is suboptimal agreement with the gold standard of patient self-reporting. These data provide further evidence supporting the integration of patient-reported outcomes into oncological clinical research and clinical practice to improve monitoring of symptoms as well as timely interventions for symptoms.

Quality of life after breast-conserving therapy and adjuvant radiotherapy for non-low-risk ductal carcinoma in situ (BIG 3-07/TROG 07.01): 2-year results of a randomised, controlled, phase 3 trial

BACKGROUND

BIG 3-07/TROG 07.01 is an international, multicentre, randomised, controlled, phase 3 trial evaluating tumour bed boost and hypofractionation in patients with non-low-risk ductal carcinoma in situ following breast-conserving surgery and whole breast radiotherapy. Here, we report the effects of diagnosis and treatment on health-related quality of life (HRQOL) at 2 years.

METHODS

The BIG 3-07/TROG 07.01 trial is ongoing at 118 hospitals in 11 countries. Women aged 18 years or older with completely excised non-low-risk ductal carcinoma in situ were randomly assigned, by use of a minimisation algorithm, to tumour bed boost or no tumour bed boost, following conventional whole breast radiotherapy or hypofractionated whole breast radiotherapy using one of three randomisation categories. Category A was a 4-arm randomisation of tumour bed boost versus no boost following conventional whole breast radiotherapy (50 Gy in 25 fractions over 5 weeks) versus hypofractionated whole breast radiotherapy (42·5 Gy in 16 fractions over 3·5 weeks). Category B was a 2-arm randomisation between tumour bed boost versus no boost following conventional whole breast radiotherapy, and category C was a 2-arm randomisation between tumour bed boost versus no boost following hypofractionated whole breast radiotherapy. Stratification factors were age at diagnosis, planned endocrine therapy, and treating centre. The primary endpoint, time to local recurrence, will be reported when participants have completed 5 years of follow-up. The HRQOL statistical analysis plan prespecified eight aspects of HRQOL, assessed by four questionnaires at baseline, end of treatment, and at 6, 12, and 24 months after radiotherapy: fatigue and physical functioning (EORTC QLQ-C30); cosmetic status, breast-specific symptoms, arm and shoulder functional status (Breast Cancer Treatment Outcome Scale); body image and sexuality (Body Image Scale); and perceived risk of invasive breast cancer (Cancer Worry Scale and a study-specific question). For each of these measures, tumour bed boost was compared with no boost, and conventional whole breast radiotherapy compared with hypofractionated whole breast radiotherapy, by use of generalised estimating equation models. Analyses were by intention to treat, with Hochberg adjustment for multiple testing. This trial is registered with ClinicalTrials.gov, NCT00470236.

FINDINGS

Between June 1, 2007, and Aug 14, 2013, 1208 women were enrolled and randomly assigned to receive no tumour bed boost (n=605) or tumour bed boost (n=603). 396 of 1208 women were assigned to category A: conventional whole breast radiotherapy with tumour bed boost (n=100) or no boost (n=98), or to hypofractionated whole breast radiotherapy with tumour bed boost (n=98) or no boost (n=100). 447 were assigned to category B: conventional whole breast radiotherapy with tumour bed boost (n=223) or no boost (n=224). 365 were assigned to category C: hypofractionated whole breast radiotherapy with tumour bed boost (n=182) or no boost (n=183). All patients were followed up at 2 years for the HRQOL analysis. 1098 (91%) of 1208 patients received their allocated treatment, and most completed their scheduled HRQOL assessments (1147 [95%] of 1208 at baseline; 988 [87%] of 1141 at 2 years). Cosmetic status was worse with tumour bed boost than with no boost across all timepoints (difference 0·10 [95% CI 0·05-0·15], global p=0·00014, Hochberg-adjusted p=0·0016); at the end of treatment, the estimated difference between tumour bed boost and no boost was 0·13 (95% CI 0·06-0·20; p=0·00021), persisting at 24 months (0·13 [0·06-0·20]; p=0·00021). Arm and shoulder function was also adversely affected by tumour bed boost across all timepoints (0·08 [95% CI 0·03-0·13], global p=0·0033, Hochberg adjusted p=0·045); the difference between tumour bed boost and no boost at the end of treatment was 0·08 (0·01 to 0·15, p=0·021), and did not persist at 24 months (0·04 [-0·03 to 0·11], p=0·29). None of the other six prespecified aspects of HRQOL differed significantly after adjustment for multiple testing. Conventional whole breast radiotherapy was associated with worse body image than hypofractionated whole breast radiotherapy at the end of treatment (difference -1·10 [95% CI -1·79 to -0·42], p=0·0016). No significant differences were reported in the other PROs between conventional whole breast radiotherapy compared with hypofractionated whole breast radiotherapy.

INTERPRETATION

Tumour bed boost was associated with persistent adverse effects on cosmetic status and arm and shoulder functional status, which might inform shared decision making while local recurrence analysis is pending.

Health-related quality of life among breast cancer survivors and noncancer controls over 10 years: Pink SWAN

BACKGROUND

The goal of this study was to compare health-related quality of life (HRQL) from diagnosis to 10 years postdiagnosis among breast cancer survivors (BCS) and women without cancer over the same period and to identify BCS subgroups exhibiting different HRQL trajectories.

METHODS

Our analysis included 141 BCS and 2086 controls from the Study of Women's Health Across the Nation (SWAN), a multiracial/ethnic cohort study of mid-life women assessed approximately annually from 1995 to 2015. Pink SWAN participants reported no cancer at SWAN enrollment and developed (cases) or did not develop (controls) incident breast cancer after enrollment. We assessed HRQL with SF-36 Mental Component Summary and Physical Component Summary scores. We modeled each as a function of case/control status, years since diagnosis, years since diagnosis squared, and the interaction terms between case/control status and the 2 time variables in linear models. We characterized heterogeneity in postdiagnosis HRQL of cases using group-based trajectories.

RESULTS

BCS had significantly lower HRQL compared with controls at diagnosis and 1 year postdiagnosis. By 2 years, BCS and controls no longer differed significantly. Among BCS, 2 trajectory groups were identified for both scores. For the Mental Component Summary, 88.4% of BCS had consistently good and 11.6% had very low scores. For the Physical Component Summary, 73.9% had good scores, and 26.1% had consistently low scores. Prediagnosis perceived stress and current smoking were related to being in the low mental trajectory group, and a higher number of comorbidities was related to being in the low physical trajectory group.

CONCLUSION

Although the majority of BCS have HRQL similar to non-cancer controls after 2 years, subgroups of BCS continue to have low HRQL. Prediagnosis stress, comorbidities, and smoking are vulnerability factors for long-term, low HRQL in BCS.

The impact of patient-reported outcome (PRO) data from clinical trials: a systematic review and critical analysis

Background

Patient-reported outcomes (PROs) are commonly collected in clinical trials and should provide impactful evidence on the effect of interventions on patient symptoms and quality of life. However, it is unclear how PRO impact is currently realised in practice. In addition, the different types of impact associated with PRO trial results, their barriers and facilitators, and appropriate impact metrics are not well defined. Therefore, our objectives were: i) to determine the range of potential impacts from PRO clinical trial data, ii) identify potential PRO impact metrics and iii) identify barriers/facilitators to maximising PRO impact; and iv) to examine real-world evidence of PRO trial data impact based on Research Excellence Framework (REF) impact case studies.

Methods

Two independent investigators searched MEDLINE, EMBASE, CINAHL+, HMIC databases from inception until December 2018. Articles were eligible if they discussed research impact in the context of PRO clinical trial data. In addition, the REF 2014 database was systematically searched. REF impact case studies were included if they incorporated PRO data in a clinical trial.

Results

Thirty-nine publications of eleven thousand four hundred eighty screened met the inclusion criteria. Nine types of PRO trial impact were identified; the most frequent of which centred around PRO data informing clinical decision-making. The included publications identified several barriers and facilitators around PRO trial design, conduct, analysis and report that can hinder or promote the impact of PRO trial data. Sixty-nine out of two hundred nine screened REF 2014 case studies were included. 12 (17%) REF case studies led to demonstrable impact including changes to international guidelines; national guidelines; influencing cost-effectiveness analysis; and influencing drug approvals.

Conclusions

PRO trial data may potentially lead to a range of benefits for patients and society, which can be measured through appropriate impact metrics. However, in practice there is relatively limited evidence demonstrating directly attributable and indirect real world PRO-related research impact. In part, this is due to the wider challenges of measuring the impact of research and PRO-specific issues around design, conduct, analysis and reporting. Adherence to guidelines and multi-stakeholder collaboration is essential to maximise the use of PRO trial data, facilitate impact and minimise research waste.

The Impact of Radiodermatitis on Breast Cancer Patients' Quality of Life During Radiotherapy: A Prospective Cohort Study

CONTEXT

In the oncology field, quality of life (QoL) is recognized as an essential component. However, few studies have evaluated radiotherapy (RT) and its adverse events, specifically radiodermatitis.

OBJECTIVES

The objective of this study was to investigate the influence of radiodermatitis severity on QoL of women with breast cancer (BC) throughout RT.

METHODS

A prospective cohort study was conducted with 100 BC patients evaluated weekly during RT. The Dermatology Life Quality Index questionnaire and the Radiation Therapy Oncology Group scale were used. The generalized estimated equations were used to examine the association between the total score of QoL and their domains, time of RT, and the radiodermatitis score, controlled by confounding factors. Estimated marginal means and 95% CIs were compared pairwise by applying Sequential Sidak.

RESULTS

The total QoL score and their domains (work/school, leisure, daily activities, symptoms, and feelings) were significantly associated with the evaluation times of RT (P < 0.001), the radiodermatitis score (P ≤ 0.002), and the interaction between timing (T) of treatment and radiodermatitis score (P < 0.001). When assessing post hoc, it was identified that the worst QoL scores were in the presence of Grade 3 (mean = 6.00) in T3 and Grade 4 (6.50; 7.00) in T5 and T6, respectively, and this difference was statistically significant.

CONCLUSIONS

RT negatively influenced the QoL of women with BC, with the greatest impact resulting from severe radiodermatitis. Actions aimed at minimizing the impairment on QoL need to be adopted to make this exhausting process less traumatic and easier to complete.

Quality of life of women with breast cancer undergoing treatment and follow-up at King Salman Armed Forces Hospital in Tabuk, Saudi Arabia

Background: Assessment of quality of life can significantly impact the diagnosis and treatment course of breast cancer, resulting in a better prognosis among patients. However, very limited data are available regarding quality of life among breast cancer patients in Saudi Arabia.

Objective: To determine the quality of life of women with breast cancer referred to the Surgery Department of King Salman Armed Forces Hospital for treatment and follow-up.

Materials and methods: This cross-sectional study used a questionnaire to assess the quality of life of 96 adult Saudi female patients diagnosed with breast cancer from January 2016 to September 2017.

Results: One-third of the surveyed patients (31.3%) were >48 years of age, and 29.2% were in the 18- to 27-year age group. Regarding marital status, 35.4% of the women were married and 8.3% were single. The highest score was observed for the physical well-being subscale (7.65±071), followed by the spiritual well-being subscale (7.19±0.66), psychological well-being scale (7.09±0.30) and social concerns subscale (7.02±0.41). Age, marital status and cancer stage differed remarkably (P=0.00) for the physical well-being subscale scores. Meanwhile, employed women differed significantly (P=0.01) in terms of psychological well-being compared to those who were not employed. The social well-being subscale score of single and married women was significantly higher than that of widowed and divorced women. Women who underwent radiation and immunotherapy had significantly higher scores for the spiritual well-being subscale.

Conclusions: Scores were determined for the physical, spiritual, psychological and social well-being scales. Age, marital status and cancer stage significantly influenced the physical well-being scale; the occupation status of the patients significantly impacted the psychological well-being scale. Social well-being can be predicted by marital status, and chemotherapy and radiation significantly impacted the spiritual well-being scale.

Prognostic Value of Post-diagnosis Health-Related Quality of Life for Overall Survival in Breast Cancer: Findings from a 10-Year Prospective Cohort in Korea

Purpose

We aimed to evaluate health-related quality of life (HRQOL) at 1-year post-diagnosis in breast cancer (BC) patients and its association with overall survival using data from the National Cancer Center Hospital.

Materials and Methods

Data of a BC cohort were first obtained between 2004 and 2006 and followed up. HRQOL was assessed using EORTC QLQ-C30 and BC specific module QLQ-BR23 few days after diagnosis and 1 year after that. We examined and compared the difference in the two HRQOL scores measured for each patient by the patient’s current survival status. The Cox proportional hazards model was fitted to evaluate the impact of HRQOL on survival, with adjustment for baseline HRQOL and other factors.

Results

Of 299 enrolled patients, 206 responded at 1-year post-diagnosis (80.6%) and were followed up for 11.6 years on average. At 1-year post-diagnosis, survivors had better HRQOL scores than those who died, although their health status was similar at baseline. Survivors reported significant increase 1 year after diagnosis in global health status and emotional scales. Between the groups, functional scales such as physical, role, and emotional were significantly different. Functional scales, including physical (adjusted hazard ratio [aHR], 0.70), role (aHR, 0.68), emotional (aHR, 0.72), and symptom scales, including fatigue (aHR, 1.34), dyspnea (aHR, 1.29), appetite loss (aHR, 1.24) were significantly associated with overall survival. Patients who were less worried about future health had favorable survival(aHR, 0.83).

Conclusion

Besides treatment-related symptoms, non-medical aspects at 1-year post-diagnosis, including functional well-being and future perspective, are predictive of long-term survival. Intervention to enhance physical, role, and emotional support for women soon after their BC diagnosis might help to improve disease survival outcomes afterwards.

Quality of life during and after adjuvant anthracycline-taxane-based chemotherapy with or without Gemcitabine in high-risk early breast cancer: results of the SUCCESS A trial

PURPOSE

In high-risk early breast cancer, adjuvant taxane-Gemcitabine combinations result in a recurrence-free survival similar to single-agent taxanes. However, haematologic toxicities and need for dose reductions are more frequent in combinations. Which option ultimately provides a better quality of life (QoL) is unknown. We compared the QoL curves before, during, and up to one year after three cycles of Fluorouracil-epirubicin-cyclophosphamide followed by three cycles of Docetaxel-Gemcitabine or Docetaxel.

METHODS

Overall, 3691 women with recent R0-resection of a primary epithelial breast cancer participated in the nationwide SUCCESS A clinical trial. The centres sent QoL questionnaires of the European Organisation for Research and Treatment of Cancer before and up to 15 months after randomisation to Docetaxel-Gemcitabine versus Docetaxel. Multilevel analysis by chemotherapy arm estimated the QoL time curves, questionnaire return, and dropout.

RESULTS

The combination caused one-point higher global QoL (95% confidence ±1; p = 0.05) and 1.1 lower odds of adherence to the outcome (95% confidence 1.0-1.1; p = 0.23) than the monotherapy. In both groups, a 10-point decrease during therapy preceded a 16-point increase after chemotherapy (p < 0.001). The secondary QoL outcomes showed transient superiority of the combination at the end of chemotherapy. Discontinuation from chemotherapy and its reasons were equal in both groups.

CONCLUSIONS

While patients perceive a one-point QoL difference as meaningless, a six-point increase is clinically relevant for them. That is, both regimens cause the same relevant long-term QoL improvement. With the similar recurrence-free survival, the lower toxicity, and the shorter chemotherapy duration in mind, taxanes without Gemcitabine are the preference. This challenges previous recommendations supporting combinations.

Methodological aspects of health-related quality of life measurement and analysis in patients with multiple myeloma

Multiple myeloma (MM) is an incurable but treatment-sensitive cancer. For most patients, this means treatment with multiple lines of anti-myeloma therapy and a life with disease- and treatment-related symptoms and complications. Health-related quality of life (HRQoL) issues play an important role in treatment decision-making. Methodological challenges in longitudinal HRQoL measurements and analyses have been identified, including non-responses (NR) to scheduled questionnaires. Publications were identified for inclusion in a systematic review of longitudinal HRQoL studies in MM, focussing on methodological aspects of HRQoL measurement and analysis. Diversity in timing of HRQoL data collection and applied statistical methods were noted. We observed a high rate of NR, but the impact of NR was investigated in only 8/23 studies. Thus, evidence-based knowledge of HRQoL in patients with MM is compromised. To improve quality of HRQoL results and their implementation in daily practice, future studies should follow established guidelines.

Longitudinal Effects of Adjuvant Endocrine Therapy on the Quality of Life of Post-menopausal Women with Non-metastatic ER+ Breast Cancer: A Systematic Review

BACKGROUND

Anti-estrogen (ER) endocrine therapy is an effective treatment strategy in reducing breast cancer mortality. This therapy has a better therapeutic index than chemotherapy but can still affect patients' quality of life (QOL) over time.

OBJECTIVE

The objectives of this systematic review were to (1) describe QOL instruments used in ER-positive (ER+) non-metastatic breast cancer trials and (2) document the longitudinal effects of adjuvant endocrine therapy on the QOL of post-menopausal women with ER+ non-metastatic breast cancer.

METHODS

We searched three electronic bibliographic databases for articles published from inception to October 2017 that described (1) a randomized controlled trial (RCT) of non-metastatic breast cancer containing an adjuvant endocrine regimen in at least one arm; (2) the use of a patient self-report measure assessing general or breast cancer-specific QOL; and (3) QOL outcomes at multiple time points during follow-up of at least 5 years. All included trials were independently evaluated by two reviewers, and data were extracted using standardized forms.

RESULTS

In total, 13 studies met our inclusion criteria and were assessed in this review. The quality of the trials was reasonably good. The top three most commonly used QOL instruments in the trials were the Functional Assessment of Cancer Therapy/Functional Assessment of Chronic Illness Therapy, the Short Form-36 and the Menopause-Specific Quality of Life. Most studies found no differences between tamoxifen and aromatase inhibitor groups in terms of global QOL. QOL data affected treatment regimen recommendations in a few cases. A meta-analysis was not feasible because the RCTs included in our review varied in terms of sample size, comparators, QOL instrument used, and timing of QOL measurement. Additionally, as no search strategy has perfect sensitivity, specificity and accuracy, there is always a chance that potentially relevant articles were missed.

CONCLUSION

This systematic review suggests that the QOL of post-menopausal women is unlikely to be adversely affected by long-term use of adjuvant endocrine therapy. Efforts are needed to improve the quality of QOL reporting in clinical trials.

Anxiety and Depression Disorders in Relation to the Quality of Life of Breast Cancer Patients with Locally Advanced or Disseminated Stage

OBJECTIVE

To evaluate patterns of association between anxiety and depression and the different elements of the construct of quality of life, in patients with locally advanced breast cancer or disseminated stages METHODS: With a single measure over time, HADS and FACIT-B scales were applied in 107 women histologically confirmed to have breast cancer, in stages IIB, IIIA, IIIB, IIIC and IV. Factor analysis and multidimensional scaling methods were used to analyze patterns of association RESULTS: In 84.1% of the patients clinical anxiety was found (95%CI, 75.8-90.5%) and clinical depression in 25.2% (95%CI, 17.3-34.6%). Factor analysis groups items of the two scales in 4 domains which accounted for 59% of the total variance, where 2 items (H11 and B8) showed high values of uniqueness and low factor loadings. Multidimensional scaling suggests five groups, showing proximity between depressive symptoms and physical symptoms, as well as between anxious symptoms and related to functionality and social and family environment CONCLUSIONS: The HADS in patients with neoplastic disease detects a high frequency of depressive and especially anxious symptoms, which makes it advisable to reevaluate their psychometric properties in patients with cancer. The association between depressive symptoms of HADS and physical symptoms of quality of life construct is in favor of the difficulty of diagnosing depressive disorder in patients with cancer, so it may be necessary to develop instruments that allow locating symptoms or clinical characteristics that facilitate this diagnosis.

The sex life of women surviving breast cancer

The diagnosis of breast cancer elicits diverse emotional responses in patients and partners. Surviving cancer has raised new needs and caretakers must understand the medical and psychological latent effects of oncology therapy. Improving patients' well-being is crucial as 19 million survivors are expected in the next decade in the United States alone. In general, sexuality contributes to one's well-being but when it is disrupted by the occurrence of cancer, women withdraw emotionally, no longer feel desirable due to esthetic damage, and become overwhelmed by the thought of sex. Alopecia and mastectomy elicit feelings of unattractiveness affecting even some women with nipple sparing mastectomy. Couples who share the psychological distress of experiencing cancer should be logically included in survivorship interventions. Hence, any support offered to the couple improves their ability to cope significantly. Treatments causing premature ovarian failure as well as adjuvant endocrine treatments deepen the effects of hypo-estrogenism on the genital modifications of arousal. Sexual rehabilitation with vaginal dilators and sensate focus exercises help to lessen pain, and reduce the couple's anxiety toward sex. In conclusion, caregivers must realize that surviving women are often reluctant to voice their needs, thus, efficient interventions must be available to everyone.

A systematic assessment of Cochrane reviews and systematic reviews published in high-impact medical journals related to cancer

OBJECTIVE

To compare cancer-related systematic reviews (SRs) published in the Cochrane Database of SRs (CDSR) and high-impact journals, with respect to type, content, quality and citation rates.

DESIGN

Methodological SR with assessment and comparison of SRs and meta-analyses. Two authors independently assessed methodological quality using an Assessment of Multiple Systematic Reviews (AMSTAR)-based extraction form. Both authors independently screened search results, extracted content-relevant characteristics and retrieved citation numbers of the included reviews using the Clarivate Analytics Web of Science database.

DATA SOURCES

Cancer-related SRs were retrieved from the CDSR, as well as from the 10 journals which publish oncological SRs and had the highest impact factors, using a comprehensive search in both the CDSR and MEDLINE.

ELIGIBILITY CRITERIA FOR SELECTING STUDIES

We included all cancer-related SRs and meta-analyses published from January 2011 to May 2016. Methodological SRs were excluded.

RESULTS

We included 346 applicable Cochrane reviews and 215 SRs from high-impact journals. Cochrane reviews consistently met more individual AMSTAR criteria, notably with regard to an a priori design (risk ratio (RR) 3.89; 95% CI 3.10 to 4.88), inclusion of the grey literature and trial registries (RR 3.52; 95% CI 2.84 to 4.37) in their searches, and the reporting of excluded studies (RR 8.80; 95% CI 6.06 to 12.78). Cochrane reviews were less likely to address questions of prognosis (RR 0.04; 95% CI 0.02 to 0.09), use individual patient data (RR 0.03; 95% CI 0.01 to 0.09) or be based on non-randomised controlled trials (RR 0.04; 95% CI 0.02 to 0.09). Citation rates of Cochrane reviews were notably lower than those for high-impact journals (Cochrane reviews: mean number of citations 6.52 (range 0-143); high-impact journal SRs: 74.45 (0-652)).

CONCLUSIONS

When comparing cancer-related SRs published in the CDSR versus those published in high-impact medical journals, Cochrane reviews were consistently of higher methodological quality, but cited less frequently.

Trajectories of quality of life following breast cancer diagnosis

PURPOSE

Although quality of life (QoL) improves over time for most breast cancer survivors (BCS), BCS may show different patterns of QoL. This study sought to identify distinct QoL trajectories among BCS and to examine characteristics associated with trajectory group membership.

METHODS

BCS (N = 653) completed baseline assessments within 8 months of diagnosis. QoL was assessed by the Functional Assessment of Cancer Therapy-Breast (FACT-B) at baseline and 6, 12, and 18 months later. Finite mixture modeling was used to determine QoL trajectories of the trial outcome index (TOI; a composite of physical well-being, functional well-being, and breast cancer-specific subscales) and emotional and social/family well-being subscales. Chi-square tests and F tests were used to examine group differences in demographic, cancer-related, and psychosocial variables.

RESULTS

Unique trajectories were identified for all three subscales. Within each subscale, the majority of BCS had consistently medium or high QoL. The TOI analysis revealed only stable or improving groups, but the emotional and social/family subscales had groups that were stable, improved, or declined. Across all subscales, women in "consistently high" groups had the most favorable psychosocial characteristics. For the TOI and emotional subscales, psychosocial variables also differed significantly between women who started similarly but had differing trajectories.

CONCLUSIONS

The majority of BCS report good QoL as they transition from treatment to survivorship. However, some women have persistently low QoL in each domain and some experience declines in emotional and/or social/family well-being. Psychosocial variables are consistently associated with improving and/or declining trajectories of physical/functional and emotional well-being.

Quality of life and anxiety in women with breast cancer before and after treatment

Objectives:

to determine the quality of life and anxiety in patients with breast cancer and the changes they experience after treatments.

Method:

prospective study. Breast cancer statistics (n=339, confidence=95%, accuracy= ± 5.32%). The quality of life questionnaires (QLQ) used were QLQ C-30 and QLQ Br23, and the State-Trait Anxiety Inventory (STAI) was used for anxiety. A multivariate analysis was performed to identify variables associated with baseline quality of life and anxiety as well as pre- and post-treatment differences. Authorization was obtained from the Ethics Committee, and informed consent was provided by all patients.

Results:

the baseline quality of life dimensions with the lowest score were future prospects (46.0/100) and sexual enjoyment (55.7/100). The dimensions with the highest score were body image (94.2/100) and role (93.3/100). The most disturbing symptoms were insomnia, fatigue and concern about hair loss. After treatment, the dimensions of physical function, role, body image, financial concerns and symptomatology worsened, whereas emotional function and future prospects improved. Severe anxiety presented as a state (48.6%) and as a trait (18.2%). The highest baseline state anxiety was associated with married-widowed status and anxiolytic medication. The greatest trait anxiety was associated with an inactive work situation, anxiolytic medication, breast swelling and advanced stage at diagnosis. After treatment, anxiety significantly decreased.

Conclusions:

After treatment, the quality of life score was positively modified, while state and trait anxiety decreased.

Quality of life in breast cancer patients: Associations with optimism and social support

Background/Objective: The purpose of this study was to examine quality of life (QoL) in breast cancer patients from Colombia and to explore the relationship between QoL, habitual optimism, and social support. Method: A sample of 95 breast cancer patients treated in a hospital in Bogotá were administered the QoL instrument EORTC QLQ-C30 and the Life Orientation Test LOT-R. Additionally, they were asked to indicate from whom (physicians, friends, nurses, etc.) they wished and received social support. Reference data for the EORTC QLQ-C30 and the LOT-R were taken from a representative sample of the general Colombian population. Results: The breast cancer patients showed detriments to their QoL on most functioning scales and symptom scales of the EORTC QLQ-C30, while their general assessments of health and QoL were not worse than those of the controls. Optimism was positively correlated with QoL. Most patients wanted and received social support from their physicians and friends/family. Conclusions: The results suggest that optimism helps patients better cope with disease. A general assessment of global QoL cannot replace the more specific assessments of the functioning domains and symptoms.

Quality of life of breast cancer survivors following breast-conserving therapy versus mastectomy: a multicenter study in Taiwan

Background

Breast cancer is the most common female malignancy worldwide. The aim of this study was to investigate the influence of surgical procedures and quality-of-care (QoC) on quality-of-life (QoL) among breast cancer survivors who underwent breast-conserving therapy (BCT) or mastectomy, and to identify provider- and patient-related factors pertaining to QoL.

Method

In this cross-sectional study, structured-questionnaires were distributed among breast cancer survivors in 19 hospitals. QoL was evaluated using the European Organization for Research and Treatment of Cancer core questionnaire (EORTC QLQ-C30) and the breast cancer specific module (EORTC QLQ-BR23). QoC is indicated by adherence to the core measures stipulated for the treatment of breast cancer. Multiple regression and hierarchical linear modeling were used for multivariate analysis.

Results

A total of 544 female survivors of Stage 0-III breast cancer were included, among whom 217 (39.9%) underwent BCT and 327 (60.1%) underwent mastectomy. Surgical modality does not appear to have a notable impact on any QoL domains except body image; i.e. patients who underwent BCT reported better body image (diff = 11.20, P < 0.001), particularly at 1-5 years after the initial treatment. Independent factors including age, education, employment, marital status, income, chemotherapy, duration since treatment, recurrence status, primary hospital accreditation level and location all appear to be correlated to QoL.

Conclusion

Patients with breast cancer should be informed of differences in QoL when discussing treatment options. Furthermore, physicians should recognize that the impact of surgical treatment modality on QoL may vary according to patients' sociodemographic and clinical characteristics.

Comparison of quality of life between 2-year and 3-or-more-year administration of leuprorelin acetate every-3-months depot in combination with tamoxifen as adjuvant endocrine treatment in premenopausal patients with endocrine-responsive breast cancer: a randomized controlled trial

Background

We conducted an open-label, randomized controlled trial evaluating the appropriate treatment duration of leuprorelin acetate 3-month depot, TAP-144-SR (3M), administered postsurgically every 3 months for 2 years versus 3 or more (up to 5) years, in combination with tamoxifen, for 5 years in premenopausal endocrine-responsive breast cancer patients and reported similar survival benefit in the two treatment groups. We hereby present patient-reported quality of life (QOL) data obtained from this trial.

Methods

Three self-administered QOL questionnaires (QOL-ACD, QOL-ACD-B, FACT-ES subscale) were used, and the difference in QOL score changes between the two groups was analyzed using a mixed-effects model for repeated measures.

Results

Eligible patients (N = 222) were randomly assigned to a 2-year (2YG, N = 112) or 3-or-more-year treatment group (3YG, N = 110). The time courses of the three QOL scores during the trial period were similar in the two groups. The mean changes in the QOL scores from week 96 were largely stable through week 240 in the 3YG, but showed significantly greater improvement in the score changes from week 96 in the 2YG than the 3YG. Symptoms associated with menopause such as hot flashes and sweating contributed to these results. Menstruation recovery was associated with significantly greater improvement of these symptoms in the 2YG than the 3YG.

Conclusions

Patient-reported menopause-associated symptoms and QOL improved after discontinuation of the LH-RH agonist administration and menstruation recovery. QOL information should be a consideration in long-term treatment.

Treatment decision-making in ductal carcinoma in situ: A mixed methods systematic review of women's experiences and information needs

OBJECTIVE

Decision-making in ductal carcinoma in situ (DCIS) is complex due to the heterogeneity of the disease. This study aimed to understand women's experience of making treatment decisions for DCIS, their information and support needs, and factors that influenced decisions.

METHODS

We searched six electronic databases, conference proceedings, and key authors. Two reviewers independently applied inclusion and quality criteria, and extracted findings. Thematic analysis was used to combine and summarise findings.

RESULTS

We identified six themes and 28 subthemes from 18 studies. Women with DCIS have knowledge deficits about DCIS, experience anxiety related to information given at diagnosis and the complexity of decision-making, and have misconceptions regarding risks and outcomes of treatment. Women's decisions are influenced by their understanding of risk, the clinical features of their DCIS, and the benefits and harms of treatment options. Women are dissatisfied with the decisional support available.

CONCLUSIONS

Informed and shared decision-making in this complex decision setting requires clear communication of information specific to DCIS and individual's, as well as decision support for patients and clinicians.

PRACTICE IMPLICATIONS

This approach would educate patients and clinicians, and assist clinicians in supporting patients to an evidence-based treatment plan that aligns with individual values and pReferences.

Cross-cultural comparison of breast cancer patients' Quality of Life in the Netherlands and Japan

Purpose

Cultural differences are hypothesized to influence patients’ Quality of Life (QoL) reports. However, there is a lack of empirical cross-cultural studies comparing QoL of patients with cancer. This study aims to compare QoL of women with breast cancer in the Netherlands and Japan, and to investigate the association of QoL with sociodemographic, clinical, and psychological variables (illness perceptions).

Methods

Dutch (n = 116) and Japanese (n = 148) women with early breast cancer undergoing chemotherapy completed the EORTC QLQ-C30 and Brief Illness Perception Questionnaire immediately before their second cycle of chemotherapy.

Results

Dutch women reported poorer Physical, Role, Emotional, and Cognitive functioning than Japanese women. Additionally, illness perceptions were significantly different in Japan and the Netherlands, but these did not vary across treatment type. In Japan, QoL of women receiving AC-chemotherapy was better than that of women receiving FEC-chemotherapy, whereas in the Netherlands, QoL did not vary as a function of chemotherapy. Illness perceptions about symptom severity, adverse consequences, and emotional representations were negatively related to most domains of patients’ QoL in both countries. Adding illness perceptions as covariates to the ANOVA analyses rendered the effects of country and treatment type on QoL non-significant.

Conclusions

Comparing Dutch and Japanese women with early breast cancer revealed important differences in treatment modalities and illness perceptions which both appear to influence QoL. Perceptions about cancer have been found to vary across cultures, and our study suggests that these perceptions should be considered when performing cross-cultural studies focusing on patient-reported outcomes.

Quality of life and functional status of patients treated for neoplastic disease in mid-northern Poland

BACKGROUND

Research into the quality of life (QoL) of people with cancer is relevant for the diagnosis of the patient's health. The collected data are used to determine somatic complaints, psychological state and the needs for nursing care.

AIM

The study aimed to assess the overall QoL and functional status in relation to basic activities of daily living of patients diagnosed with cancer in our region.

METHODS

Using questionnaires for assessment of QoL and functional status (Barthel Index), we surveyed 500 adult patients (250 women and 250 men) diagnosed with neoplasms of varying etiology and staying at home.

RESULTS

The average QoL (± standard deviation) in the study population was low and amounted to 34.5 (±22.7) on the scale of 0-100. The most intensive symptoms were fatigue (69.9 ± 25.5) and pain (62.7 ± 29.1). The greatest demand for nursing care concerned grooming and bathing.

CONCLUSIONS

The QoL and functioning scores of patients with neoplasmic disease were low. The caregivers (usually nurses) should strive to minimize patients' fatigue and pain.

Patient-reported outcomes in ductal carcinoma in situ: A systematic review

Ductal carcinoma in situ (DCIS) is a pre-invasive breast cancer with excellent prognosis but with potential adverse impacts of diagnosis and treatment on quality of life and other patient-reported outcomes (PROs). We undertook a systematic review to synthesise current evidence about PROs following diagnosis and treatment for DCIS. We searched five electronic databases (from database inception to November 2015), cross-referenced and contacted experts to identify studies that reported PROs after DCIS treatment. Two reviewers independently applied inclusion and quality criteria, and extracted findings. Of 2130 papers screened, 23 were eligible, reporting 17 studies. Short- and long-term PRO evidence about differences between DCIS treatment options was lacking. Evidence pooled across treatments indicated core aspects of quality of life (physical, role, social, emotional function, pain, fatigue) and psychological distress (anxiety, depression) were impacted significantly initially, with most aspects returning to population norms by 6-12 months, and all by 2 years post-operatively. Fears of recurrence and dying from breast cancer were exaggerated, occurred early and persisted for many years. Sexuality and body image impacts were generally low and resolved within 1-3 months after surgery. A minority of women experienced considerable impact, including depression and sexual issues associated with body image problems. Well-powered PRO studies are required to track recovery trajectories and long-term impacts of the range of contemporary and emerging local and systemic treatments for DCIS. PRO data would enable care providers to prepare patients for short-term sequelae and enable patients who have treatment options to exercise preferences in choosing among them.

Analysing data from patient-reported outcome and quality of life endpoints for cancer clinical trials: a start in setting international standards

Measures of health-related quality of life (HRQOL) and other patient-reported outcomes generate important data in cancer randomised trials to assist in assessing the risks and benefits of cancer therapies and fostering patient-centred cancer care. However, the various ways these measures are analysed and interpreted make it difficult to compare results across trials, and hinders the application of research findings to inform publications, product labelling, clinical guidelines, and health policy. To address these problems, the Setting International Standards in Analyzing Patient-Reported Outcomes and Quality of Life Endpoints Data (SISAQOL) initiative has been established. This consortium, directed by the European Organisation for Research and Treatment of Cancer (EORTC), was convened to provide recommendations on how to standardise the analysis of HRQOL and other patient-reported outcomes data in cancer randomised trials. This Personal View discusses the reasons why this project was initiated, the rationale for the planned work, and the expected benefits to cancer research, patient and provider decision making, care delivery, and policy making.

Patient-provider communication and hormonal therapy side effects in breast cancer survivors

Side effects from hormonal therapy (HT) for breast cancer treatment occur frequently and are associated with worse quality of life and HT non-adherence. Whether improved patient-physician communication is associated with patients' reporting of side effects is unknown. We undertook this study to assess factors associated with women's reports of HT side effects. Between December 2012 and April 2013, we conducted a cross-sectional survey of breast cancer patients undergoing HT in an urban medical center. Descriptive statistics, univariate analyses, and multivariate analyses were used to evaluate associations. Of the 100 participants, 67% reported having HT side effects. However, when prompted, an additional 9% reported experiencing specific HT-related symptoms. Despite very high communication scores, one-third of participants reported they had not discussed side effects with providers. Multivariate analysis showed that after controlling for age, education, race, and medication beliefs, women who had difficulty asking providers for more information were more likely to report side effects (odds ratio 8.27, 95% confidence interval 1.01-69.88). Although HT side effects often occur and are bothersome, patient-provider discussions about side effects remain suboptimal. Providers should actively ask patients about medication side effects so that they can be addressed to improve quality of life and potentially, medication adherence.

Differences in quality of life between American and Chinese breast cancer survivors

OBJECTIVE

It has been speculated that cancer survivors in Asia may have lower quality of life (QOL) compared with their Western counterparts. However, no studies have made international comparisons in QOL using a comprehensive measure. This study aimed to compare Chinese breast cancer survivors' QOL with US counterparts and examine if demographic and medical factors were associated with QOL across groups.

METHOD

The sample consisted of 159 breast cancer patients (97 Chinese and 62 American) who completed the Functional Assessment for Cancer Therapy Breast Cancer (FACT-B) scale before the start of radiotherapy in Shanghai, China and Houston, USA.

RESULTS

Higher income was associated with higher QOL total scores in both Chinese and American cancer patients, but QOL was not significantly associated with other factors including age, education, disease stage, mastectomy, and chemotherapy. Consistent with hypotheses, compared to their US counterparts, Chinese breast cancer survivors reported lower QOL and all four subdimensions including functional well-being (FWB), physical well-being (PWB), emotional well-being (EWB), and social well-being (SWB); they also reported more breast cancer-specific concerns (BCS). Differences were also clinically significant for Functional Assessment for Cancer Therapy General (FACT-G) scale total scores and the FWB subscale. After controlling for demographic and medical covariates, these differences remained except for the SWB and BCS. Furthermore, Chinese breast cancer survivors receiving chemotherapy reported significantly lower FACT-G scores than those who did not, but this difference did not emerge among US breast cancer survivors.

DISCUSSION

Chinese breast cancer survivors reported poorer QOL on multiple domains compared to US women. Findings indicate that better strategies are needed to help improve the QOL of Chinese breast cancer survivors, especially those who underwent chemotherapy.

'Trial Exegesis': Methods for Synthesizing Clinical and Patient Reported Outcome (PRO) Data in Trials to Inform Clinical Practice. A Systematic Review

Purpose

The CONSORT extension for patient reported outcomes (PROs) aims to improve reporting, but guidance on the optimal integration with clinical data is lacking. This study examines in detail the reporting of PROs and clinical data from randomized controlled trials (RCTs) in gastro-intestinal cancer to inform design and reporting of combined PRO and clinical data from trials to improve the ‘take home’ message for clinicians to use in practice.

Materials and Methods

The case study was undertaken in gastro-intestinal cancer trials. Well-conducted RCTs reporting PROs with validated instruments were identified and categorized into those combining PRO and clinical data in a single paper, or those separating data into linked primary and supplemental papers. Qualitative methods were developed to examine reporting of the critical interpretation of the trial results (trial exegesis) in the papers in relation of the PRO and clinical outcomes and applied to each publication category. Results were used to inform recommendations for practice.

Results

From 1917 screened abstracts, 49 high quality RCTs were identified reported in 36 combined and 15 linked primary and supplemental papers. In-depth analysis of manuscript text identified three categories for understanding trial exegesis: where authors reported a “detailed”, “general”, or absent PRO rationale and integrated interpretation of clinical and PRO results. A total of 11 (30%) and 6 (16%) combined papers reported “detailed” PRO rationale and integrated interpretation of results although only 2 (14%) and 1 (7%) primary papers achieved the same standard respectively. Supplemental papers provide better information with 11 (73%) and 3 (20%) achieving “detailed” rationale and integrated interpretation of results. Supplemental papers, however, were published a median of 20 months after the primary RCT data in lower impact factor journals (median 16.8 versus 5.2).

Conclusion

It is recommended that single papers, with detailed PRO rationale and integrated PRO and clinical data are published to optimize trial exegesis. Further work to examine whether this improves the use of PRO data to inform practice is needed.

Quality of life in breast cancer sufferers

Purpose - The purpose of this paper is to measure health-related quality of life (QOL) among patients with early stage cancer breast under curative treatment at department of oncology and nuclear medicine at Ain Shams University Hospitals. Identify factors affecting QOL among these patients. Design/methodology/approach - A cross-sectional study measured QOL among early stage female breast cancer (BC) patients and determined the main factors affecting their QOL. Three interviewer administered questionnaires were used. Findings - The physical domain mostly affected in BC patients and the functional domain least. Socio-demographic factors that significantly affected BC patients QOL scores were patient age, education, having children and family income. Specific patient characteristics include caregiver presence - a factor that affected different QOL scores. Age at diagnosis, affection in the side of the predominant hand, post-operative chemotherapy and difficulty in obtaining the medication were the disease-related factors that affected QOL scores. Originality/value - The final model predicting QOL for early stage female BC patients included age, education and difficulty in obtaining the medication as determinants for total QOL score. Carer presence was the specific patient characteristic that affected different QOL scores.

Graphical displays of patient-reported outcomes (PRO) for use in clinical practice: What makes a pro picture worth a thousand words?

Patient-reported outcomes (PROs) report patients' assessments of the impact of a health condition and its treatment, and can promote patient-centered care.

OBJECTIVES

To address the effectiveness of graphic display of PRO data in clinical practice by reviewing existing literature, and current recommendations, regarding graphic presentations of PROs.

METHODS

We performed an integrated literature review to identify themes and emerging principles guiding effective graphic display of PRO data. The findings were placed in the context of the literature informing graphical presentation of other clinical data.

RESULTS

Although a large body of literature informs graphical presentation of clinical data, only nine empirical studies addressed presentation of PROs. Four major themes emerged: many patients and most clinicians can accurately interpret some PRO graphs; interpretation accuracy, personal preference, and perceived level of understanding are sometimes discordant; patient age and education may predict PRO graph comprehension; patients tend to prefer simpler graphs than do clinicians.

CONCLUSIONS

Little empirical research specifically addresses graphic representation of PRO data. A single format may not work optimally for both clinicians and patients.

PRACTICE IMPLICATIONS

Patients and clinicians may or may not comprehend PRO data when graphically presented. Further research to determine best practices for presenting PROs optimally is needed.

Targeted drugs and Psycho-oncological intervention for breast cancer patients

Personalized medicine is a new field based on molecular biology and genomics in which targeted tumor therapies are administered to patients. Psycho-oncology is a complementary approach that considers social and psychological aspects of patients as part of the treatments for cancer patients.

The aim of this mini-review is to weigh clinical benefits for breast cancer patients of both treatments and possibily enhance benefits by modulating the use of both interventions. We have compared and evaluated on the one hand the use of anti Vascular Endothelial Growth Factor and, on the other hand, psycho-oncological interventions in metastatic and non-metastatic breast cancer patients.

Both treatments did not increase survival of metastatic breast cancer patients, while in a selected study psycho-oncological interventions extended lifespan of non-metastatic breast cancer patients and ameliorate psychological and social factors of metastatic breast cancer patients. Because the two approaches address completely different aspects of cancer patients, if the comparison is limited to the extension of survival, the value of these two treatments cannot be assessed and compared.

It is likely that by comparing patients reported outcomes, possibly by using standardized Quality of Life questionnaires, both patients and health care providers can weigh the benefits of the two treatments. It is therefore important to evaluate the use of cancer patients’ quality of life measures as a mean to improve their experiences about life and treatment, and possibly to extend their survival.

Patient-reported pain and other quality of life domains as prognostic factors for survival in a phase III clinical trial of patients with advanced breast cancer

Background

Patient-reported outcomes have been associated with survival in numerous studies across cancer types, including breast cancer. However, the Brief Pain Inventory-Short Form (BPI-SF) and the Rotterdam Symptom Checklist (RSCL) have rarely been investigated in this regard in breast cancer.

Methods

Here we describe a post hoc analysis of the prognostic effect of baseline scores of these instruments on survival in a phase III trial of patients with advanced breast cancer who received gemcitabine plus paclitaxel or paclitaxel alone after anthracycline-based adjuvant or neoadjuvant therapy. The variables for this analysis were baseline BPI-SF “worst pain” and BPI-SF “pain interference” scores, and four RSCL subscales (each transformed to 0–100). Univariate and multivariate Cox models were used, the latter in the presence of 11 demographic/clinical variables. Kaplan-Meier curves and log-rank tests were used to compare survival for patients by BPI-SF or RSCL scores.

Results

Of 529 randomized patients, 286 provided BPI-SF data and 336 provided RSCL data at baseline. Univariate analyses identified BPI-SF worst pain and pain interference (both hazard ratios [HR], 1.07 for a 1-point increase; both p ≤ 0.0061) and three of four RSCL subscales [activity level, physical distress, and health-related quality of life (HRQOL) (HR, 0.86–0.91 for 10-point increase all p ≤ 0.0104)], to have significant prognostic effect for survival. BPI-SF worst pain (p = 0.0342) and RSCL activity level (p = 0.0004) were prognostic in the multivariate analysis. Median survival for patients categorized by BPI-SF worst pain score was 23.8 (n = 91), 17.9 (n = 94) and 14.6 (n = 94) months for scores 0, 1–4, and 5–10, respectively (log-rank p = 0.0065). Median survival was 23.8 and 14.6 months for patients (n = 330) with above- and below-median RSCL activity level scores respectively (log-rank p < 0.0001).

Conclusion

Pretreatment BPI-SF worst pain and RSCL activity scores provide distinct prognostic information for survival in patients receiving paclitaxel or gemcitabine plus paclitaxel for advanced breast cancer even after controlling for multiple demographic and clinical factors.

Efficacy and safety of pirarubicin plus capecitabine versus pirarubicin plus cyclophosphamide in Chinese node-negative breast cancer patients: a 4-year open-label, randomized, controlled study

This study aimed to evaluate the efficacy and safety of adjuvant chemotherapy with pirarubicin plus capecitabine (AX regimen) in Chinese node-negative breast cancer (BCa) patients. Two hundred eighty Chinese pT1-2N0M0 BCa patients under 70 years of age were equally and randomly assigned to receive four cycles of adjuvant therapy with the AX regimen or pirarubicin and cyclophosphamide (AC regimen) between January 2010 and May 2011. End points included overall survival (OS), disease-free survival (DFS), chemotherapy-induced toxicities, and quality of life (QoL). The 4-year DFS (AX vs. AC, 93.6 vs. 92.9 %, P = 0.761) and OS (97.1 vs. 96.4 %, P = 0.965) were similar between the two treatment arms. The AX group, compared to the AC group, experienced significantly less frequent grade III/IV vomiting (11.4 vs. 26.4 %, P < 0.001), whereas the incidence of other grade III/IV chemotherapy-associated toxicities was comparable between the two groups (all P values >0.05). Use of the AX regimen was associated with significantly higher QoL scores in the domains of physical, role, and social functions than the AC regimen (P values <0.05), although the two regimens were similar in the domains of emotional and cognitive functions (all P values >0.05). In comparison with the AC regimen, AX adjuvant chemotherapy is equally beneficial for node-negative BCa patients younger than 70 years with respect to OS and DFS. The AX regimen is primarily advantageous over the AC regimen based on less frequent severe toxicities and better health-related QoL.

New approaches for improving outcomes in breast cancer in Europe

Considerable progress has been made in breast cancer treatment in Europe over the past three decades, yet survival rates for metastatic disease remain poor, underlining the need for further advances. While the use of predictive biomarkers for response to systemic therapy could improve drug development efficiency, progress in identifying such markers has been slow. The currently inadequate classification of breast cancer subtypes is a further challenge. Improved understanding of the molecular pathology of the disease has led to the identification of new targets for drug treatment, and evolving classifications should reflect these developments. Further ongoing challenges include difficulties in finding optimal combinations and sequences of systemic therapies, circumventing multidrug resistance and intra-tumor heterogeneity, problems associated with fragmentation in clinical trials and translational research efforts. Adoption of some of the strategies identified in this article may lead to further improvements in outcomes for patients with the disease.
