6th and 7th International consensus guidelines for the management of advanced breast cancer (ABC guidelines 6 and 7).

This manuscript describes the Advanced Breast Cancer (ABC) international consensus guidelines updated at the last two ABC international consensus conferences (ABC 6 in 2021, virtual, and ABC 7 in 2023, in Lisbon, Portugal), organized by the ABC Global Alliance. It provides the main recommendations on how to best manage patients with advanced breast cancer (inoperable locally advanced or metastatic), of all breast cancer subtypes, as well as palliative and supportive care. These guidelines are based on available evidence or on expert opinion when a higher level of evidence is lacking. Each guideline is accompanied by the level of evidence (LoE), grade of recommendation (GoR) and percentage of consensus reached at the consensus conferences. Updated diagnostic and treatment algorithms are also provided. The guidelines represent the best management options for patients living with ABC globally, assuming accessibility to all available therapies. Their adaptation (i.e. resource-stratified guidelines) is often needed in settings where access to care is limited.

Impact of COVID-19 on patients with metastatic breast cancer: REthink Access to Care and Treatment survey results.

Aim: Patients with metastatic breast cancer (MBC) may be vulnerable to changes in healthcare management, safety standards and protocols that occurred during the COVID-19 pandemic. Materials & methods: The REthink Access to Care & Treatment (REACT) survey assessed USA-based patient perspectives on COVID-19-related impacts to their MBC treatment experience between 27 April 2021 and 17 August 2021. Results: Participants (n = 341; 98.5% females, mean age 50.8 years) reported that overall oncology treatment quality was maintained during the pandemic. Delayed/canceled diagnostic imaging was reported by 44.9% of participants while telemedicine uptake was high among participants (80%). Conclusion: Overall, MBC care was minimally affected by the pandemic, possibly due to the expanded use of telemedicine, informing MBC management for future public health emergencies.

The COVID-19 pandemic has forced healthcare providers to change the way that healthcare is delivered. These changes could particularly affect people with metastatic breast cancer (MBC), an advanced stage of cancer that has spread to other parts of the body. The authors of this study used a web-based survey to ask 341 volunteers with MBC how the pandemic has affected their cancer treatment. The authors found that people with MBC thought that the quality of their care stayed the same during the pandemic. Most people (80%) surveyed were able to use telemedicine, the remote delivery of care by phone or computer, to replace in-person visits to their doctor. However, almost half of people surveyed reported delays or cancellation of their diagnostic imaging appointments. Overall, this study shows that the COVID-19 pandemic did not affect peoples' opinions of their MBC care. Increased use of telemedicine may have contributed to the lack of disruption in care. These findings will help guide MBC care during future public health emergencies.

Progression-free survival and quality of life in metastatic breast cancer: The patient perspective.

INTRODUCTION: Treatment advances for metastatic breast cancer (mBC) have improved overall survival (OS) in some mBC subtypes; however, there remains no cure for mBC. Considering the use of progression-free survival (PFS) and other surrogate endpoints in clinical trials, we must understand patient perspectives on measures used to assess treatment efficacy. OBJECTIVE: To explore global patient perceptions of the concept of PFS and its potential relation to quality of life (QoL). MATERIALS AND METHODS: Virtual roundtables in Europe and the United States and interviews in Japan with breast cancer patients, patient advocates, and thought leaders. Discussions were recorded, transcribed, and analyzed thematically. RESULTS: Lengthened OS combined with no worsening or improvement in QoL remain the most important endpoints for mBC patients. Time when the disease is not progressing is meaningful to patients when coupled with improvements in QoL and no added treatment toxicity. Clinical terminology such as "PFS" is not well understood, and participants underscored the need for patient-friendly terminology to better illustrate the concept. Facets of care that patients with mBC value and that may be related to PFS include relief from cancer-related symptoms and treatment-related toxicities as well as the ability to pursue personal goals. Improved communication between patients and providers on managing treatment-related toxicities and addressing psychosocial challenges to maintain desired QoL is needed. CONCLUSION: While OS and QoL are considered the most relevant endpoints, patients also value periods of time without disease progression. Incorporation of these considerations into the design and conduct of future clinical trials in mBC, as well as HTA and reimbursement decision-making, is needed to better capture the potential value of a therapeutic innovation.

Global analysis of advanced/metastatic breast cancer: Decade report (2005-2015).

Approximately 0.5 million people worldwide die from metastatic breast cancer (mBC) every year. This manuscript provides an overview on the status of mBC in several regions of the world, highlighting the gaps in care, resources, and support available for patients with mBC. Primary research was conducted in 2015 and 2016, comprising four global qualitative and quantitative surveys of approximately 15,000 individuals in 34 countries. Secondary research was conducted using literature reviews of peer-reviewed publications, patient survey reports, and media or online articles. There have been modest improvements in mBC outcomes over the past decade. Patients are not provided with adequate information about mBC. There is a need for open discussion with patients and caregivers about realistic goals; however, physicians are not trained in communicating with patients about their disease. Maintaining patients' quality of life is a crucial goal; however, this has not improved, and in some cases, may have declined in the past decade. Public awareness and understanding of mBC is limited, with damaging consequences for patients and caregivers. Issues affecting employment remain relevant to patients with mBC and their caregivers. Globally, mBC is associated with a substantial economic burden. Relationships with caregivers are crucial to patients with mBC, and caregiver support needs are often overlooked. A strong and united global effort among healthcare professionals, including clinicians, oncologists, pharmaceutical manufacturers, payers, and policy makers, and with advocates, families, and patients, is necessary to improve the outcome and quality of life for patients with mBC.

Obstacles, Opportunities and Priorities for Advancing Metastatic Breast Cancer Research.

In January 2016, the Metastatic Breast Cancer Alliance (the Alliance) convened a think tank of stakeholders from academia, government, industry, and patient advocacy to discuss gaps and opportunities in clinical and translational research in metastatic breast cancer. Priorities that emerged from the meeting included the following: the need for innovative preclinical model systems to study metastatic disease; increased sharing of resources and data; collaboration across cancer care teams and scientists; biorepositories for studies to identify biomarkers for treatment response; creation of patient registries to increase access to clinical trials and tissue procurement; and redesign of clinical trials in metastatic breast cancer.

Evolving psychosocial, emotional, functional, and support needs of women with advanced breast cancer: Results from the Count Us, Know Us, Join Us and Here & Now surveys.

Although medical advances have marginally improved survival of women with advanced breast cancer, their psychosocial, emotional, and functional needs remain unmet. Two surveys, Count Us, Know Us, Join Us (Count Us) and Here & Now (H&N), were conducted to understand the unique challenges faced by women with advanced breast cancer and to identify ways of addressing these issues. A total of 1577 women with advanced breast cancer (Count Us, N = 1273; H&N, N = 304) participated in the two surveys, which revealed several previously unreported challenges. Nearly half the women felt isolated and worried, and slightly more than half experienced declines in income because of change in employment; 41% of women felt that support from family and friends decreased over time, and many patients believed information about advanced breast cancer was inadequate and difficult to find. Concerted efforts by people who care for and support women with advanced breast cancer are urgently needed to address these issues.
