Current practice patterns and gaps in guideline-concordant breast cancer survivorship care

Ongoing Symptoms and Concerns Experienced by Low-Risk Breast Cancer Survivors Following Active Treatment

INTRODUCTION

Little is known about the symptom burden of breast cancer survivors with early-stage disease. Many studies have focused on symptoms of patients who are undergoing or recently completed systemic therapy. However, with the increased use of Oncotype DX, the proportion of early-stage hormone receptor-positive patients who undergo chemotherapy has declined, making existing studies of the symptom experience less useful for these patients.

OBJECTIVE

The aim of this study was to assess symptom burden for early-stage breast cancer survivors.

METHODS

Eligible survivors had stage I-II, estrogen receptor (ER)- or progesterone receptor (PR)-positive and HER2neu-negative breast cancer, did not receive chemotherapy, were 6 months-5 years post-diagnosis, and were cancer-free. Survivors were enrolled at the University of Wisconsin Breast Center follow-up visits and were emailed a link to a patient-reported outcomes (PRO) survey. Survey domains were informed by American Cancer Society/American Society of Clinical Oncology (ACS/ASCO) survivorship guidelines and survivor/provider stakeholders. The prevalence of clinically significant symptoms are reported.

RESULTS

Overall, 98 patients participated. On average, participants were 61.3 years of age (standard deviation [SD] 11.5) and 2.5 years post-diagnosis (SD 1.2); 71.3% underwent breast-conserving surgery. The average item-level missingness rate was low (2.0%). Most survivors (86.2%) experienced symptoms (38.8% reporting one to two symptoms; 47.9% reporting more than three symptoms).

CONCLUSIONS

Early-stage breast cancer survivors report a high symptom burden. Given nearly 50% of survivors report more than three symptoms, many topics may not be discussed or addressed during time-limited follow-up visits. Some symptoms, such as sexual health, may be less feasible to address in-clinic given their complex/sensitive nature. Use of PROs allows for a comprehensive evaluation and identification of unrecognized needs, representing an opportunity to improve survivorship care.

Engaging survivor and oncologist stakeholders to develop a patient-reported outcome assessment to use as a component of survivorship care

PURPOSE

Incorporating patient-reported outcomes (PROs) into survivorship care may improve the comprehensiveness of follow-up. The objective was to engage stakeholders to develop a PRO assessment of survivors' symptoms and concerns for use during breast cancer follow-up.

METHODS

We convened patient and oncologist stakeholder advisory groups to develop an initial PRO assessment including survivorship domains of importance, measurement instruments, and clinically significant thresholds, and revise the assessment based on feedback from community focus groups and two rounds of iterative pilot testing with survivors.

RESULTS

Stakeholders identified key domains and measurement instruments, including recurrence symptoms, treatment side effects, adherence, mental health, and sexual health. Ninety-four survivors completed the PRO assessment in the initial pilot test (median age 62 years, median 2 years from diagnosis). Most (89/93) reported questions were easy to understand. The level of missingness was low. The most common threshold-level symptoms/concerns were hot flashes (46%), fatigue (35%), back pain (31%), joint pain (31%), and anxiety (30%). The PRO assessment was revised to clarify symptom causality and desire to discuss with a provider. In a follow-up pilot study with 20 survivors, the most common symptoms were chest/breast discomfort (50%) and anxiety (25%).

CONCLUSIONS

We leveraged stakeholder input to develop a comprehensive PRO assessment to use to assess breast cancer survivors' well-being. Our PRO assessment is acceptable to survivors. Future research will focus on the integration of the PRO assessment into clinical care.

Exploring long-term breast cancer survivors' care trajectories using dynamic time warping-based unsupervised clustering

OBJECTIVES

Long-term breast cancer survivors (BCS) constitute a complex group of patients, whose number is estimated to continue rising, such that, a dedicated long-term clinical follow-up is necessary.

MATERIALS AND METHODS

A dynamic time warping-based unsupervised clustering methodology is presented in this article for the identification of temporal patterns in the care trajectories of 6214 female BCS of a large longitudinal retrospective cohort of Spain. The extracted care-transition patterns are graphically represented using directed network diagrams with aggregated patient and time information. A control group consisting of 12 412 females without breast cancer is also used for comparison.

RESULTS

The use of radiology and hospital admission are explored as patterns of special interest. In the generated networks, a more intense and complex use of certain healthcare services (eg, radiology, outpatient care, hospital admission) is shown and quantified for the BCS. Higher mortality rates and numbers of comorbidities are observed in various transitions and compared with non-breast cancer. It is also demonstrated how a wealth of patient and time information can be revealed from individual service transitions.

DISCUSSION

The presented methodology permits the identification and descriptive visualization of temporal patterns of the usage of healthcare services by the BCS, that otherwise would remain hidden in the trajectories.

CONCLUSION

The results could provide the basis for better understanding the BCS' circulation through the health system, with a view to more efficiently predicting their forthcoming needs and thus designing more effective personalized survivorship care plans.

Reviewing the Landscape of Cancer Survivorship: Insights from Dr. Lidia Schapira's Programs and Beyond

The constantly escalating population of cancer survivors worldwide has prompted a focused exploration of their unique needs and experiences within the context of healthcare medicine. This review initiates its analysis inspired by Dr. Lidia Schapira's insightful keynote conference on the Survivorship 1.0 and Survivorship 2.0 Programs, shedding light on their implementation challenges and setting the stage for a comprehensive analysis of cancer survivorship initiatives. Within the transformed landscape of cancer care, patient-centric strategies embedded in cancer survivorship programs comprising vital elements such as connection, support, and education are presented. While placing cancer recurrence surveillance at the forefront, the review underlines concern regarding the potential oversight of the enduring impact on mental and physical health. Dr. Schapira's insights further extend into the exploration of mental health challenges faced by survivors, promoting an examination of diverse strategies to address these concerns. Furthermore, the discussion continues toward promising areas of research, notably Precision Medicine's role in de-escalating cancer therapies, and advocates for measures such as early cancer awareness and timely referrals to supportive services. Highlighting the significance of education, the role of online resources in enhancing the knowledge of healthcare practitioners and future generations in cancer care is then explored. The paper concludes by presenting some of the most prominent global current survivorship programs, identifying critical knowledge gaps in cancer care and projecting future developments aimed at delivering accurate and holistic care, improving the quality of life for survivors, and enhancing both mental and physical well-being. Drawing upon the insights from Dr. Schapira, this review lays the groundwork for a nuanced exploration of cancer survivorship and its multifaceted implications.

Cancer survivor late-effects, chronic health problems after cancer treatment: what's the evidence from population and registry data and where are the gaps?

PURPOSE OF REVIEW

Improvements in cancer treatment have led to more people living with and beyond a cancer diagnosis but survivors may have increased health problems as they age. The purpose of this review is to critically evaluate population data exploring incidence of late effects for cancer survivors.

RECENT FINDINGS

18 studies were identified between 2013 and 2023 that explored the impact on survivors' physical and emotional health. Patients who had been treated at least 2 years previously for cancer had significant cardiovascular risk factors compared with age-matched controls. Women with breast cancer were more likely to have cardiovascular disease, including hypertension, arrythmias and congestive heart failure. This was associated with anthracyclines and/or trastuzumab as part of systemic anti-cancer therapy. Survivors of colorectal cancer were three times more likely to have acute kidney injury than age-matched controls. Stress and mood disorders were higher in survivors of testicular cancer and prostate cancer.

SUMMARY

Population studies are important to identify the 'real world' consequences of cancer and its treatment beyond clinical trials. Knowledge is critical for managing an ageing cancer population. Data to personalise cancer survivorship care, not only helps determine potential health risks, but can improve secondary prevention, emotional health, recovery, and long-term outcomes.

Survivorship care in breast cancer: understanding implementation barriers through the lens of the Theoretical Domains Framework

BACKGROUND

Breast cancer survivorship guidelines with specific recommendations on managing long-term effects are available, but uptake in clinical practice remains low. Using the lens of the Theoretical Domains Framework, we aimed to understand key factors in guideline-concordant management of long-term effects to inform future implementation efforts in clinical practice contexts.

METHODS

As part of a broader survey of oncologists, a theory-guided questionnaire was developed. Oncologists were asked to report level of agreement with Theoretical Domains Framework-based statements, current usage and perceived value of survivorship resources, and frequency of managing long-term effects in routine care. Data analyses included psychometric assessment of the questionnaire, descriptive summaries of theoretical domains and survivorship resources, and multivariable logistic regression models.

RESULTS

In total, 217 oncologists completed the Theoretical Domains Framework-based questionnaire; 54% of oncologists reported "always or almost always" evaluating physical effects at routine survivorship appointments, while 34% did so for psychosocial effects. In regression models, Environmental Context and Resources was the only theoretical domain found to be statistically significantly associated with "always or almost always" evaluating both physical (odds ratio = 0.29, 95% confidence interval = 0.09 to 0.80) and psychosocial (odds ratio = 0.09, 95% confidence interval = 0.02 to 0.35) effects.

CONCLUSIONS

Findings support application of the Theoretical Domains Framework in understanding oncologists' behaviors and perceived barriers in managing long-term effects in breast cancer survivors. In future implementation efforts, this theory-informed approach can be used to target relevant domains and strategies focused on embedding guideline recommendations in the clinical context through structured resources and environmental supports.

Factors Associated with Long-Term Dietary Supplement Use among Korean Breast Cancer Survivors: A Cross-Sectional Study

PURPOSE

The factors associated with the dietary supplement (DS) use of Asian breast cancer survivors in consideration of the duration of use and types of DS have not been well established.

METHODS

We recruited 693 Korean female breast cancer survivors at two university-affiliated hospitals and collected study data through a self-administered questionnaire and a review of medical records. A multiple logistic regression analysis was conducted to evaluate the multivariable-adjusted association between DS use and study variables.

RESULTS

The prevalence of any (≥2 weeks) and long-term (≥6 months) DS use among study participants was 48.2% and 12.0%, respectively. Education level, alcohol use, adequate physical activity (≥150 min/week), and time lapse after cancer diagnosis were positively associated with any DS use. Among DS users, as compared with short-term (≥2 weeks and <6 months) users, long-term users were more likely to have a higher cancer stage, more diverse cancer treatment modalities, a shorter time since cancer diagnosis, and lower fear of cancer recurrence. When we repeated the analysis for each DS type, time lapse after cancer diagnosis showed a consistently inverse association with long-term use of the most frequently consumed DS (multivitamins, followed by vitamin D/calcium, vitamin C, and omega-3). The number of cancer treatment modalities was positively associated with the long-term use of multivitamins and vitamin D/calcium. Alcohol consumption and low bone mineral density were positively associated with long-term vitamin D/calcium use.

CONCLUSIONS

The factors associated with DS use differed by the duration of DS use and specific DS type. Long-term DS use was more frequently associated with cancer-related factors.

A mixed method study of medical oncologists' perceived barriers and motivators to addressing long-term effects in breast cancer survivors

Purpose

The purpose of this study was to identify oncologist-reported barriers and motivators in addressing long-term effects with breast cancer survivors.

Methods

This study is a secondary analysis of data from a survey of U.S. medical oncologists (n = 217) about breast cancer survivorship care in clinical practice. Using both closed- and open-ended questions, we asked oncologists to report barriers and motivators they perceived in addressing long-term effects with breast cancer patients. Descriptive statistics were used to summarize and rank items endorsed by oncologists in analyses of quantitative data; content analysis was used to identify salient categories of barriers and motivators in qualitative data.

Results

Key barriers to managing physical long-term effects included lack of time during appointments (n = 128 oncologists, 59%) and perceived lack of evidence-based interventions (n = 89, 41%). With respect to psychosocial effects, oncologists reported lack of knowledge (n = 88, 40.6%) and challenges making referrals to mental health providers (n = 115, 53%). From the qualitative data, three distinct barrier categories emerged: “Competing priorities during brief appointments;” “Discussing long-term effects—Who? What? When?;” and “Beyond my expertise and comfort level.” Two motivator categories emerged: “I owe it to them;” and “Giving people a life worth living.”

Conclusion

Oncologists’ key motivators for addressing long-term effects were focused on professional values, relationships with survivors, and their commitment to prioritizing patients' quality of life. Future efforts should leverage oncologists' professional and interpersonal motivators to enhance the delivery of survivorship care for breast cancer.
