Abstract
Aim: To report treatment patterns and quality of life (QoL) in HER2-negative advanced breast cancer patients. Methods: Data were drawn from a cross-sectional survey in Europe and USA. Results: Hormone plus targeted therapy was the most frequent first-line (1L, 62%) and second-line (2L, 45%) treatment for HR+/HER2-patients. Chemotherapy was most frequent at third-line or greater (3L+, 39%) for HR+/HER2- patients, 2L (51%) and 3L+ (48%) for triple negative breast cancer (TNBC) patients. Time to progression was 13.8 (2L) and 11.0 (3L+) months for HR+/HER2- patients. No comparisons were observed for TNBC patients. EQ-5D-5L scores were highest in patients at 1L and lowest at 3L+. Conclusion: Reduced QoL and treatment response were reported in patients at later lines of therapy.

Abstract
OBJECTIVES Advanced breast cancer (ABC) is an incurable disease. The number of people living with ABC has increased globally. Disparities in ABC care exist at both individual and system levels. ABC cases in most low- and middle-income countries (LMICs) are underreported due to a lack of national cancer registries. Harmonized guidelines for resource stratification and capacity building in LMICs are under way. DATA SOURCES MEDLINE, Cochrane, and Google Scholar databases were used. CONCLUSION To improve ABC outcomes and resolve disparities, more robust health systems or pathways need to be developed across the cancer continuum in addition to social education. IMPLICATIONS FOR NURSING PRACTICE So far, the ABC specialist nurse role has been variable globally, and to conquer such variability, an international online nurse education and training program is in practice.

Abstract
PURPOSE Many studies on cancer patients investigate the impact of treatment on health-related quality of life (QoL). Typically, QoL is measured longitudinally, at baseline and at predefined timepoints thereafter. The question is whether, at a given timepoint, patients who return their questionnaire (available cases, AC) have a different QoL than those who do not return their questionnaire (non-AC). METHODS We employed augmented inverse probability weighting (AIPW) to estimate the average QoL of non-AC in two studies on advanced-stage cancer patients. The AIPW estimator assumed data to be missing at random (MAR) and used machine learning (ML)-based methods to estimate answering probabilities of individuals at given timepoints as well as their reported QoL, as a function of auxiliary variables. These auxiliary variables were selected by medical oncologists based on domain expertise. We aggregated results both by timepoint and by time until death and compared AIPW estimates to the AC averages. Additionally, we used a pattern mixture model (PMM) to check sensitivity of our AIPW estimates against violation of the MAR assumption. RESULTS Our study included 1927 patients with advanced pancreatic and 797 patients with advanced breast cancer. The AIPW estimate for average QoL of non-AC was below the average QoL of AC when aggregated by timepoint. The difference vanished when aggregated by time until death. PMM estimates were below AIPW estimates. CONCLUSIONS Our results indicate that non-AC have a lower average QoL than AC. However, estimates for QoL of non-AC are subject to unverifiable assumptions about the missingness mechanism.

Dynamic changes in quality of life, psychological status, and body image in women who underwent a mastectomy as compared with breast reconstruction: an 8-year follow up. Breast Cancer 2023; 30:226-240. [PMID: 36319889 DOI: 10.1007/s12282-022-01413-6] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 02/21/2022] [Accepted: 10/27/2022] [Indexed: 02/24/2023]
Abstract
BACKGROUND Surgical decisions and methods of surgery highly influence long term QoL for breast cancer (BC) survivors. This study is aimed towards an exploration of the dynamic changes in quality of life (QoL), anxiety/depression status, and body image (BI) among women with BC who received a mastectomy compared with those receiving breast reconstruction (BR) within an 8-year follow-up period. METHODS Women with major BC surgeries were invited to complete the World Health Organization Quality of Life-Brief (WHOQOL-BREF), the European quality of life five dimensions questionnaire (EQ-5D), and a body image scale within 8 years of surgery. Kernel smoothing methods were applied to describe dynamic changes in QoL, anxiety/depression, and BI at different time points. Linear mixed effects models were constructed to identify the interaction between time, different types of surgery, and the determinants of QoL in these patients. RESULTS After 1:10 propensity score matching, a total of 741 women who had undergone a BR and mastectomy were included. The BR group exhibited a high WHOQOL QoL score one to five years after surgery with some fluctuations. The mastectomy group had comparatively stable QoL scores on WHOQOL items and were less depressed/anxious. The BR group generally showed fluctuating, higher BI scores two years after surgery, but they exhibited more anxiety/depression during follow up for 8 years. Medical comorbidities, the status of anxiety/depression, and BI were the major factors influencing all domains and items of the WHOQOL BREF among women with BC. CONCLUSION The mastectomy group showed a decreased trend toward depression in patients with BC. The BR group showed a significant improvement in QoL in the first 5 years with massive fluctuations. These findings should be considered and discussed in patient participatory decision-making and promotion of QoL for breast cancer survivors.

Psychosocial Aspects of Living Long Term with Advanced Cancer and Ongoing Systemic Treatment: A Scoping Review. Cancers (Basel) 2022; 14:cancers14163889. [PMID: 36010883 PMCID: PMC9405683 DOI: 10.3390/cancers14163889] [Citation(s) in RCA: 6] [Impact Index Per Article: 3.0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/04/2022] [Revised: 08/01/2022] [Accepted: 08/04/2022] [Indexed: 11/16/2022] Open
Abstract
(1) Background: Studies examining the psychosocial impact of living long term on systemic treatment in advanced cancer patients are scarce. This scoping review aimed to answer the research question “What has been reported about psychosocial factors among patients living with advanced cancer receiving life-long systemic treatment?”, by synthesizing psychosocial data, and evaluating the terminology used to address these patients; (2) Methods: This scoping review was conducted following the five stages of the framework of Arksey and O’Malley (2005); (3) Results: 141 articles published between 2000 and 2021 (69% after 2015) were included. A large variety of terms referring to the patient group was observed. Synthesizing qualitative studies identified ongoing uncertainty, anxiety and fear of disease progression or death, hope in treatment results and new treatment options, loss in several aspects of life, and worries about the impact of disease on loved ones and changes in social life to be prominent psychosocial themes. Of 82 quantitative studies included in the review, 76% examined quality of life, 46% fear of disease progression or death, 26% distress or depression, and 4% hope, while few studies reported on adaptation or cognitive aspects. No quantitative studies focused on uncertainty, loss, or social impact; (4) Conclusion and clinical implications: Prominent psychosocial themes reported in qualitative studies were not included in quantitative research using specific validated questionnaires. More robust studies using quantitative research designs should be conducted to further understand these psychological constructs. Furthermore, the diversity of terminology found in the literature calls for a uniform definition to better address this specific patient group in research and in practice.

Effects of decisional conflict, decision regret and self-stigma on quality of life for breast cancer survivors: A cross-sectional, multisite study in China. J Adv Nurs 2022; 78:3261-3272. [PMID: 35396872 DOI: 10.1111/jan.15250] [Citation(s) in RCA: 7] [Impact Index Per Article: 3.5] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/21/2021] [Revised: 02/20/2022] [Accepted: 03/23/2022] [Indexed: 01/03/2023]
Abstract
AIMS To examine the differences in decisional conflict, decision regret, self-stigma and quality of life among breast cancer survivors who chose different surgeries, as well as the effects of decisional conflict, decision regret and self-stigma on quality of life. DESIGN Observational study. METHODS Paper and online surveys were used to collect data from March to September 2020. The Chinese version of the Decisional Conflict Scale, Decision Regret Scale, Self-Stigma Form and Functional Assessment of Cancer Treatment-B were used to measure the corresponding health outcomes for breast cancer survivors who chose different surgeries from three university-affiliated hospitals. One-way analysis of variance, Pearson's correlation coefficient and hierarchical multiple regression analysis were used for data analysis. RESULTS Among the 448 participants, only 21% chose breast conservative surgery, while 79% chose mastectomy with or without reconstruction. Women who chose mastectomy with reconstruction reported higher decisional conflict (p = .028) and more decision regret (p = .013) than women who chose breast conservative surgery; women who chose mastectomy without reconstruction indicated higher decisional conflict (p = .015), more decision regret (p < .001), and higher self-stigma (p = .034) than women who chose breast conservative surgery. Decisional conflict (r = -.430), decision regret (r = -.495), and self-stigma (r = -.561) were negatively correlated with quality of life. After controlling for sociodemographic and clinical variables, decisional conflict and decision regret explained 19.7% and self-stigma explained 12.9% of the variance in quality of life. CONCLUSION Decisional conflict, decision regret and self-stigma vary according to different breast surgeries and are greatly associated with the quality of life of breast cancer survivors. IMPACT Future studies are warranted to investigate the decision-making process and the underlying reasons for surgical choices. Decision support strategies pre-surgery are needed to inform women about the risks and benefits of surgery options. Moreover, psychosocial support post-surgery is warranted to relieve women's self-stigma, thus improving their quality of life.

Abstract
Background Quality of life (QoL) is one of the treatment outcome measures in patients with breast cancer. In this study, we measured the QoL of women with breast cancer at Universiti Kebangsaan Malaysia Medical Centre (UKMMC) and identified the associated factors.
Methodology This cross-sectional study was conducted from October 2017 to December 2017 and involved female patients with breast cancer. The QoL scores and domains were determined using the EuroQol EQ-5D-5L, and were presented as the utility value and visual analog scores, respectively. Results We recruited a total of 173 women, aged 33–87 years. The median VA score was 80.00 (interquartile range [IQR] 70.00–90.00); the median utility value was 0.78 (interquartile range [IQR] 0.65–1.00. Women who did not take traditional medicine had a higher utility index score of 0.092 (95% CI 0.014–0.171), and women with household income of RM3000–5000 had a higher utility index score of 0.096 (95% CI 0.011–0.180). Conclusion Traditional medicine consumption and household income were significantly associated with lower QoL. The pain/discomfort domain was the worst affected QoL domain and was related to traditional medicine use and household income. Addressing pain management in patients with breast cancer and the other factors contributing to lower QoL may improve the QoL of breast cancer survivors in the future.

Abstract
PURPOSE Performing a systematic review and meta-analysis to assess the evidence of intra-arterial therapies in liver metastatic breast cancer (LMBC) patients. METHODS A systemic literature search was performed in PubMed, EMBASE, SCOPUS for studies regarding intra-arterial therapies in LMBC patients. Full text studies of LMBC patients (n ≥ 10) published between January 2010 and December 2020 were included when at least one outcome among response rate, adverse events or survival was available. Response rates were pooled using generalized linear mixed models. A weighted estimate of the population median overall survival (OS) was obtained under the assumption of exponentially distributed survival times. RESULTS A total of 26 studies (1266 patients) were included. Eleven articles reported on transarterial radioembolization (TARE), ten on transarterial chemoembolization (TACE) and four on chemo-infusion. One retrospective study compared TARE and TACE. Pooled response rates were 49% for TARE (95%CI 32-67%), 34% for TACE (95%CI 22-50%) and 19% for chemo-infusion (95%CI 14-25%). Pooled median survival was 9.2 months (range 6.1-35.4 months) for TARE, 17.8 months (range 4.6-47.0) for TACE and 7.9 months (range 7.0-14.2) for chemo-infusion. No comparison for OS was possible due to missing survival rates at specific time points (1 and 2 year OS) and the large heterogeneity. CONCLUSION Although results have to be interpreted with caution due to the large heterogeneity, the superior response rate of TARE and TACE compared to chemo-infusion suggests first choice of TARE or TACE in chemorefractory LMBC patients. Chemo-infusion could be considered in LMBC patients not suitable for TARE or TACE. LEVEL OF EVIDENCE 3a.

Measuring Quality of Life Using Patient-Reported Outcomes in Real-World Metastatic Breast Cancer Patients: The Need for a Standardized Approach. Cancers (Basel) 2021; 13:cancers13102308. [PMID: 34065805 PMCID: PMC8151772 DOI: 10.3390/cancers13102308] [Citation(s) in RCA: 8] [Impact Index Per Article: 2.7] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/01/2021] [Revised: 04/20/2021] [Accepted: 05/10/2021] [Indexed: 12/04/2022] Open
Abstract
Simple Summary Metastatic breast cancer (MBC) remains incurable despite treatment improvements. The health-related quality of life is a multidimensional entity which covers physical, psychological and social dimensions. It is an important outcome particularly in patients with metastatic disease, as the primary goal of therapy is no longer curation, but to provide the best possible quality of life weighted against treatment risks and adverse symptoms. Patient-reported outcomes reflecting the quality of life are usually measured with validated questionnaires to evaluate treatment strategies based on symptom burden and to improve care delivery. This review shares insights into the role of patient-reported outcome measurements in MBC patients and describes the heterogeneity of current questionnaires. We conclude that an up-to-date and standardized outcome set is needed, containing relevant domains referring to individual needs to improve the quality of life assessment among MBC patients. This is a prerequisite to learn about how they could impact the clinical care pathway. Abstract Metastatic breast cancer (MBC) patients are almost always treated to minimize the symptom burden, and to prolong life without a curative intent. Although the prognosis of MBC patients has improved in recent years, the median survival after diagnosis is still only 3 years. Therefore, the health-related quality of life (HRQoL) should play a leading role in making treatment decisions. Heterogeneity in questionnaires used to evaluate the HRQoL in MBC patients complicates the interpretability and comparability of patient-reported outcomes (PROs) globally. In this review, we aimed to provide an overview of PRO instruments used in real-world MBC patients and to discuss important issues in measuring HRQoL. Routinely collecting symptom information using PROs could enhance treatment evaluation and shared decision-making. Standardizing these measures might help to improve the implementation of PROs, and facilitates collecting and sharing data to establish valid comparisons in research. This is a prerequisite to learn about how they could impact the clinical care pathway. In addition, the prognostic value of intensified PRO collection throughout therapy on survival and disease progression is promising. Future perspectives in the field of PROs and MBC are described.

Abstract
BACKGROUND This study evaluates the cost-effectiveness of pertuzumab with trastuzumab biosimilar and docetaxel as initial treatment for HER2-positive metastatic breast cancer (MBC) in Singapore. METHODS A partitioned survival model with three health states was developed to evaluate the cost-effectiveness of trastuzumab biosimilar and docetaxel with or without pertuzumab from a healthcare system perspective over a 15-year time horizon for patients with HER2-positive MBC. Key clinical inputs were derived from the CLEOPATRA trial. Health state utilities were derived from the literature and direct medical costs were obtained from local public healthcare institutions. RESULTS The base-case resulted in an incremental cost-effectiveness ratio (ICER) of SGD366,658 (USD272,244) per quality-adjusted life-year (QALY) gained. One-way sensitivity analyses showed that the ICER was sensitive to utilities in the progression-free state, price of pertuzumab and time horizon. When the price for trastuzumab reference biologic (branded) was applied, the ICER was even higher (SGD426,996 [USD317,045]/QALY). CONCLUSION Although trastuzumab biosimilar reduced the cost of the pertuzumab combination regimen, the ICER remained high and was not cost effective in Singapore's context. As pertuzumab contributed 80% of the overall combination treatment cost, price reductions for pertuzumab will be required to improve the cost-effectiveness of combination treatment to an acceptable level.
