Breast Cancer in Women Older Than 80 Years

Characterization of time toxicity in older patients with metastatic breast cancer

PURPOSE

Recognizing that receiving healthcare can be time intensive and burdensome, time toxicity has been conceptualized as the time spent by patients seeking healthcare. This study investigates the association between age at diagnosis and time toxicity for patients with Metastatic Breast Cancer (MBC) and identifies major components of care that confer the greatest time toxicity.

METHODS

We conducted a retrospective cohort study among patients with MBC aged 67 or older using the SEER-Medicare database. We assessed time toxicity using the number of encounter days patients interacted with the healthcare system per 100 days, within the first year of starting cancer treatment. We used a Poisson model to analyze the association between age and encounter days, adjusting for clinical and sociodemographic factors. We stratified the mean encounter days for each age cohort by treatment types.

FINDINGS

The final sample included 2949 patients; 51.4% were between 70 and 79 years old, and 81.3% were white. Although unadjusted analysis showed an association between older age and more encounter days (Rate Ratio (RR) 1.12; 95% CI 1.02, 1.22), there was no significant association after adjusting for comorbidities and treatment type. Patients with more than three comorbidities had significantly higher encounter days compared to those without comorbidities [RR 1.36 (95% CI 1.26, 1.46)]. Receipt of radiotherapy [RR: 1.45 95% CI (1.37, 1.54)] was associated with more encounter days compared to not receiving radiotherapy, while receipt of bone-modifying agents was associated with fewer encounter days compared to not using Bone modifying agents [RR 0.75 (95% CI 0.70, 0.79)].

CONCLUSION

Our study identified comorbidities and cancer treatment modality, including radiotherapy, as the factors affecting time toxicity in older patients with MBC. Assessment of an individual's comorbid medical conditions and types of treatment planned are crucial to understanding age-related impacts on encounter days and to support shared decision making in older patients.

Palbociclib in Older Patients with Advanced/Metastatic Breast Cancer: A Systematic Review

BACKGROUND

Palbociclib in combination with endocrine therapy is approved for treatment of hormone receptor-positive (HR+)/human epidermal growth factor receptor 2-negative (HER2-) advanced breast cancer. In addition to clinical trials, several real-world studies have evaluated the effectiveness of palbociclib. With increased life expectancy in the general population, breast cancer in older women is also expected to increase.

OBJECTIVE

The aim was to systematically review evidence from both clinical trials and real-world studies for palbociclib treatment outcomes in older patients with HR+/HER2- advanced/metastatic breast cancer (a/mBC). Older patients are often underrepresented in clinical trials, and real-world evidence (RWE) will enrich the analysis of palbociclib outcomes in this subgroup of patients.

DESIGN

A systematic literature search in PubMed, EMBASE, and Cochrane Library through May 4, 2023, yielded 2355 unique articles. A total of 52 articles (13 and 39 articles reporting results from seven randomized controlled trials [RCTs] and 37 RWE studies, respectively) were included based on study eligibility criteria.

RESULTS

All RCTs used age cutoffs of ≥ 65 years to define older population (n = 722; 437 received palbociclib); all RWE studies, except one with an age cutoff of > 60 years, had age cutoffs of ≥ 65 years or higher to define older population (n = 9840; 7408 received palbociclib). Overall, in studies that compared efficacy (progression-free survival [seven RCTs, 20 RWE studies], overall survival [four RCTs, 11 RWE studies], tumor response [three RWE studies], and clinical benefit rate [one RCT, two RWE studies]) and safety outcomes (three RCTs, three RWE studies) between older and younger patients, palbociclib showed similar benefits, regardless of age. Results from two RCTs and two RWE studies showed that global quality of life (QoL) was maintained in older patients receiving palbociclib. Overall, palbociclib dose modifications (two RWE studies), dose reductions (one RCT, seven RWE studies), and treatment discontinuation rates (three RCTs, three RWE studies) were higher in older patients compared with younger patients; however, these differences did not appear to adversely impact efficacy outcomes.

CONCLUSIONS

In this systematic review, data from RCTs showed that palbociclib was effective, well tolerated, and maintained QoL in older patients with HR+/HER2- a/mBC. Palbociclib treatment in older patients in real-world settings was associated with similar clinical benefit as in RCTs.

Measures of functional status in older patients treated with palbociclib for advanced breast cancer

INTRODUCTION

Limited data are available on the effects of treatment for advanced breast cancer (ABC) in older patients because this population has limited enrollment in clinical trials. Data generated from the prospective, noninterventional POLARIS study of patients with hormone receptor-positive/human epidermal growth factor receptor 2-negative ABC may help bridge the gap in our understanding of the tolerability and outcomes in this vulnerable population.

MATERIALS AND METHODS

We evaluated measures of geriatric impairments and activities of daily living in patients with ABC aged ≥70 years in POLARIS to evaluate the change within six months of palbociclib initiation. Geriatric impairments and activities of daily living (functional) status were assessed using the Geriatric 8 (G8) and Activities of Daily Living (ADL) screening tools. The G8, ADL, and Eastern Cooperative Oncology Group performance status (ECOG PS) scores were assessed at baseline and month six through end of treatment with palbociclib. ECOG PS scores were also stratified by G8 and ADL score severity subgroups (G8: ≤14 = impaired subgroup; >14 = not at all impaired subgroup; ADL: <18 = dependent subgroup, 18 = independent subgroup).

RESULTS

At data cutoff in November 2020, of 1282 POLARIS patients of all ages, 287 (22.4%) were ≥ 70 years old and completed ≥6 months of palbociclib therapy. At baseline, 117 (45%; n = 260) of these patients had an ECOG PS score of 0, 143 (55%; n = 260) had ECOG PS score > 0, 248 (86%) had G8 scores (mean [SD] 13.6 [2.14]), and 256 (89%) had ADL scores (17.7 [1.03]) among the available 287 patients. At six months, 102 (40%; n = 255) had an ECOG PS score of 0, 153 (60%; n = 255) had ECOG PS score > 0, 198 (69%) had G8 scores (13.6 [1.99]), and 211 (74%) had ADL scores (17.6 [1.22]) among the 287 available patients. There was no mean change (standard deviation) from baseline to 6 months in mean ECOG PS scores (0.0 [0.61], P = 0.24), G8 scores (0.0 [2.17], P = 0.89), or ADL scores (0.0 [1.00], P = 0.62).

DISCUSSION

In this subgroup analysis of older patients with ABC from POLARIS, functional status and impairment outcomes were preserved in older patients receiving palbociclib. G8, ADL, and ECOG PS scores were generally maintained during the first six months of palbociclib therapy.

Safety and Efficacy of Lenvatinib in Very Old Patients with Unresectable Hepatocellular Carcinoma

BACKGROUND

Data concerning the use of lenvatinib in very old patients (≥ 80 years) are limited, although the incidence of hepatocellular carcinoma (HCC) in this patient population is constantly increasing.

OBJECTIVE

This analysis aimed to evaluate the efficacy and safety of lenvatinib in a large cohort of very old patients (≥ 80 years) with unresectable HCC.

PATIENTS AND METHODS

The study was conducted on a cohort of 1325 patients from 46 centers in four Western and Eastern countries (Italy, Germany, Japan, and the Republic of Korea) who were undergoing first-line treatment with lenvatinib between July 2010 and February 2022. Patients were stratified according to age as very old (≥ 80 years) and not very old (< 80 years).

RESULTS

The median overall survival (OS) was 15.7 months for patients < 80 years old and 18.4 months for patients ≥ 80 years old [hazard ratio (HR) = 1.02, 95% confidence interval (CI) 0.84-1.25, p = 0.8281]. Median progression free survival (PFS) was 6.3 months for patients < 80 years old and 6.5 months for patients ≥ 80 years old (HR = 1.07, 95% CI 0.91-1.25, p = 0.3954). No differences between the two study groups were found in terms of disease control rate (DCR; 80.8% versus 78.8%; p = 0.44) and response rate (RR; 38.2% versus 37.9%; p = 0.88). Patients < 80 years old experienced significantly more hand-foot skin reaction (HFSR) grade ≥ 2 and decreased appetite grade ≥ 2. Conversely, patients ≥ 80 years old experienced significantly more fatigue grade ≥ 2. In the very old group, parameters associated with prognosis were AFP, albumin-bilirubin (ALBI) grade, Barcelona Clinic Liver Cancer (BCLC), and Child-Pugh score. BCLC stage was the only independent predictor of overall survival (OS; HR = 1.59, 95% CI 1.11-2.29, p = 0.01115).

CONCLUSIONS

Our study highlights the same efficacy and safety of lenvatinib between very old and not very old patients.

Locoregional Ablative Radiation Therapy for Patients With Breast Cancer Unsuitable for Surgical Resection

PURPOSE

Patients with breast cancer who are unsuitable for surgical resection are typically managed with palliative systemic therapy alone. We report outcomes of 5-fraction ablative radiation therapy for nonresected breast cancers.

METHODS AND MATERIALS

This is a retrospective analysis of an institutional registry of patients with breast cancer who were unsuitable for resection and underwent 35 to 40 Gy/5 fractions to the primary breast tumor or regional lymph nodes from 2014 to 2021. Primary outcomes were cumulative incidence of local failure and grade ≥3 toxicity (Common Terminology Criteria for Adverse Events, version 5.0).

RESULTS

We reviewed 57 patients who received 61 treatment courses (median age of 81 years; range, 38-99). Unresectable tumor (10%), patient refusal (18%), medical inoperability (35%), and metastatic disease (37%) were the causes of not having surgery. Five patients (8%) had previously undergone adjuvant locoregional radiation therapy. Fifty-four percent (n = 33/61) of treatment courses targeted the breast only, 31% (n = 19/61) both the breast and lymph nodes, and 15% (n = 9/61) the lymph nodes only. Sixty-seven percent (n = 35/52) of the courses that targeted the breast were delivered with partial breast irradiation and 33% (n = 17/52) with whole breast radiation therapy (median dose of 25 Gy in 5 fractions) ± simultaneous integrated boost to the primary tumor. Most primary tumors (65%, n = 34/52) and target lymph nodes (61%, n = 17/28) were treated with a dose of 35 Gy in 5 fractions. Most treatments (52%) were delivered with intensity modulated radiation therapy (IMRT). Radiation therapy was delivered daily (20%), every other day (18%), twice weekly (36%), or weekly (26%). The 2-year cumulative incidence of local failure was 11.4% and grade≥3 toxicity was 15.1%. The grade ≥3 toxicity was 6.5% for IMRT treatments, versus 7.7% for non-IMRT treatments targeting partial breast or lymph nodes (hazard ratio, 1.13, P = .92), versus 38.9% for non-IMRT treatments targeting the entire breast (hazard ratio, 6.91, P = .023). All grade ≥3 toxicity cases were radiation dermatitis. No cases of brachial plexopathy were observed.

CONCLUSIONS

Thirty-five to 40 Gy in 5 fractions is a safe and effective breast stereotactic body radiation therapy (SBRT) regimen and may be an attractive option for patients who are not surgical candidates. Highly conformal techniques (ie, IMRT or partial breast irradiation) were associated with a reduced risk of toxicity and should be the preferred treatment approaches.

Heart Failure in the Elderly: the Role of Biological and Sociocultural Aspects Related to Sex

PURPOSE OF REVIEW

Heart failure (HF) entails poor prognosis, with high morbidity and mortality burden, particularly in elderly patients. Notably, important sex differences have been described between men and women with HF. In this regard, some biological and sociocultural aspects related to sex may play a key role in the different development and prognosis of HF in elderly men and women.

RECENT FINDINGS

Important differences between men and women with HF, especially in the elderly population, have been specifically addressed in recent studies. Consequently, specific differences in biological and sociocultural aspects have been found to associate differences in pathophysiology, baseline clinical profile, and prognosis according to sex. Moreover, differences in comorbidities and frailty and other geriatric conditions, frequent in elderly population with HF, have also been described. Biological and sociocultural differences related to sex are key in the different clinical presentation and prognosis of heart failure in elderly women. Further studies will be required to better understand some other underlying reasons that may differently impact prognosis in elderly patients with HF.

Breast cancer screening and diagnosis in older adults women in Brazil: why it is time to reconsider the recommendations

Introduction

Breast cancer screening in women of 70 years of age or older remains controversial due to a lack of studies that include women of this age.

Methods

This ecological study evaluated data from the Brazilian National Health Service (SUS) on breast cancer screening and staging in this age group compared to 50-69-year olds, for Brazil as a whole and for its geographical regions, between 2013 and 2019. A secondary database was obtained from the outpatient data system of the SUS's Informatics Department, the Brazil Oncology Panel, the Brazilian Institute of Geography and Statistics, the Supplementary Health Agency and the Online Mortality Atlas.

Results

There was a marked reduction in screening in women ≥70 years of age (annual percent change [APC] -3.5; p < 0.001) compared to those of 50-69 years of age (APC-2.2; p = 0.010). There was a trend towards an increase in clinical staging, with a greater occurrence of stages III and IV in the ≥70 group (44.3%) compared to the women of 50-69 years of age (40.8%; p < 0.001).

Conclusion

Considering the increasing age of the Brazilian population and the heterogeneity among older adults women, screening for the over-70s within the SUS merits greater debate insofar as the implementation of public policies is concerned.

SaBrcada: Survival Intervals Prediction for Breast Cancer Patients by Dimension Raising and Age Stratification

(1) Background: Breast cancer is the second leading cause of cancer death among women. The accurate prediction of survival intervals will help physicians make informed decisions about treatment strategies or the use of palliative care. (2) Methods: Gene expression is predictive and correlates to patient prognosis. To establish a reliable prediction tool, we collected a total of 1187 RNA-seq data points from breast cancer patients (median age 58 years) in Fragments Per Kilobase Million (FPKM) format from the TCGA database. Among them, we selected 144 patients with date of death information to establish the SaBrcada-AD dataset. We first normalized the SaBrcada-AD dataset to TPM to build the survival prediction model SaBrcada. After normalization and dimension raising, we used the differential gene expression data to test eight different deep learning architectures. Considering the effect of age on prognosis, we also performed a stratified random sampling test on all ages between the lower and upper quartiles of patient age, 48 and 69 years; (3) Results: Stratifying by age 61, the performance of SaBrcada built by GoogLeNet was improved to a highest accuracy of 0.798. We also built a free website tool to provide five predicted survival periods: within six months, six months to one year, one to three years, three to five years, or over five years, for clinician reference. (4) Conclusions: We built the prediction model, SaBrcada, and the website tool of the same name for breast cancer survival analysis. Through these models and tools, clinicians will be provided with survival interval information as a basis for formulating precision medicine.

Eligibility criteria in clinical trials in breast cancer: a cohort study

BACKGROUND

Breast cancer (BC) is the most common cancer type in women. The purpose of this study was to assess the eligibility criteria in recent clinical trials in BC, especially those that can limit the enrollment of older patients as well as those with comorbidities and poor performance status.

METHODS

Data on clinical trials in BC were extracted from ClinicalTrials.gov. Co-primary outcomes were proportions of trials with different types of the eligibility criteria. Associations between trial characteristics and the presence of certain types of these criteria (binary variable) were determined with univariate and multivariate logistic regression.

RESULTS

Our analysis included 522 trials of systemic anticancer treatments started between 2020 and 2022. Upper age limits, strict exclusion criteria pertaining to comorbidities, and those referring to inadequate performance status of the patient were used in 204 (39%), 404 (77%), and 360 (69%) trials, respectively. Overall, 493 trials (94%) had at least one of these criteria. The odds of the presence of each type of the exclusion criteria were significantly associated with investigational site location and trial phase. We also showed that the odds of the upper age limits and the exclusion criteria involving the performance status were significantly higher in the cohort of recent trials compared with cohort of 309 trials started between 2010 and 2012 (39% vs 19% and 69% vs 46%, respectively; p < 0.001 for univariate and multivariate analysis in both comparisons). The proportion of trials with strict exclusion criteria was comparable between the two cohorts (p > 0.05). Only three of recent trials (1%) enrolled solely patients aged 65 or 70 and older.

CONCLUSIONS

Many recent clinical trials in BC exclude large groups of patients, especially older adults, individuals with different comorbidities, and those with poor performance status. Careful modification of some of the eligibility criteria in these trials should be considered to allow investigators to assess the benefits and harms of investigational treatments in participants with characteristics typically encountered in clinical practice.

Real-world data on home end-of-life care for older adults with cancer: A retrospective claims data analysis

Background

Cancer incidence is expected to increase with population aging, making the availability of places for treating patients with terminal cancer a pressing issue. However, little is known about the actual state of home end-of-life care (HEC) in Japan.

Objective

The objective of this study was to examine the real-world state of HEC for older adults with cancer.

Methods

The Yokohama Original Medical Database was used to identify the cohort. Data of target patients was extracted based on three criteria: age ≥65 years, malignant neoplasm diagnosis, and having a specific billing code of HEC. Multivariable linear and logistic regression models were used to evaluate the association between age groups and HEC services or outcome indexes.

Results

Overall, 1323 people (554 and 769 aged < 80 and ≥ 80 years, respectively; men, 59.2%) had planned to receive HEC. The < 80 years group had more frequent emergent home visits than the ≥ 80-year group (P < 0.001), but the number of monthly home visits was similar between the two groups (P = 0.267). The rate of emergent admission was 5.9% in the ≥ 80-year group, which was higher than that in the < 80-year group (3.1%; P = 0.018). Conversely, the rates of central venous nutrition and opioid use were higher in the < 80-year group than those in the ≥ 80-year group.

Conclusions

This study reported patterns of use of HEC among older adults with cancer in the terminal stage. Our findings may provide the basis for providing HEC for older adults with cancer.

Women 75 Years Old or Older: To Screen or Not to Screen?

Breast cancer is the most common cancer in women, with the incidence rising substantially with age. Older women are a vulnerable population at increased risk of developing and dying from breast cancer. However, women aged 75 years and older were excluded from all randomized controlled screening trials, so the best available data regarding screening benefits and risks in this age group are from observational studies and modeling predictions. Benefits of screening in older women are the same as those in younger women: early detection of smaller lower-stage cancers, resulting in less invasive treatment and lower morbidity and mortality. Mammography performs significantly better in older women with higher sensitivity, specificity, cancer detection rate, and positive predictive values, accompanied by lower recall rates and false positives. The overdiagnosis rate is low, with benefits outweighing risks until age 90 years. Although there are conflicting national and international guidelines about whether to continue screening mammography in women beyond age 74 years, clinicians can use shared decision making to help women make decisions about screening and fully engage them in the screening process. For women aged 75 years and older in good health, continuing annual screening mammography will save the most lives. An informed discussion of the benefits and risks of screening mammography in older women needs to include each woman's individual values, overall health status, and comorbidities. This article will review the benefits, risks, and controversies surrounding screening mammography in women 75 years old and older and compare the current recommendations for screening this population from national and international professional organizations. ^©RSNA, 2023 Quiz questions for this article are available through the Online Learning Center.

Chemotherapy refusal and subsequent survival in healthy older women with high genomic risk estrogen receptor-positive breast cancer

BACKGROUND

Patients with estrogen receptor (ER)-positive, HER2-negative breast cancer (BC), and high-risk 21-gene recurrence score (RS) results benefit from chemotherapy. We evaluated chemotherapy refusal and survival in healthy older women with high-RS, ER-positive BC.

METHODS

Retrospective review of the National Cancer Database (2010-2017) identified women ≥ 65 years of age, with ER-positive, HER2-negative, high-RS (≥ 26) BC. Patients with Charlson Comorbidity Index ≥ 1, stage III/IV disease, or incomplete data were excluded. Women were compared by chemotherapy receipt or refusal using the Cochrane-Armitage test, multivariable logistical regression modeling, the Kaplan-Meier method, and Cox's proportional hazards modeling.

RESULTS

6827 women met study criteria: 5449 (80%) received chemotherapy and 1378 (20%) refused. Compared to women who received chemotherapy, women who refused were older (71 vs 69 years), were diagnosed more recently (2014-2017, 67% vs 61%), and received radiation less frequently (67% vs 71%) (p ≤ 0.05). Refusal was associated with decreased 5-year OS for women 65-74 (92% vs 95%) and 75-79 (85% vs 92%) (p ≤ 0.05), but not for women ≥ 80 years old (84% vs 91%; p = 0.07). On multivariable analysis, hazard of death increased with refusal overall (HR 1.12, 95% CI 1.04-1.2); but, when stratified by age, was not increased for women ≥ 80 years (HR 1.10, 95% CI 0.80-1.51).

CONCLUSIONS

Among healthy women with high-RS, ER-positive BC, chemotherapy refusal was associated with decreased OS for women ages 65-79, but did not impact the OS of women ≥ 80 years old. Genomic testing may have limited utility in this population, warranting prudent shared decision-making and further study.

[Epidemiology, diagnosis and extension]

Breast cancer is the most common cancer in women. The elderly, whose numbers have been increasing, constitute a population in their own right, because of the many co-morbidities they suffer from. The epidemiology of breast cancer, particularly in elderly women, is described here, as well as the diagnosis and the assessment of extension, which do not differ from the rest of the population.

Breast Cancer in Geriatric Patients: Current Landscape and Future Prospects

Breast cancer is the most common cancer diagnosed among women worldwide and more than half are diagnosed above the age of 60 years. Life expectancy is increasing and the number of breast cancer cases diagnosed among older women are expected to increase. Undertreatment, mostly due to unjustifiable fears of advanced-age and associated comorbidities, is commonly practiced in this group of patients who are under-represented in clinical trials and their management is not properly addressed in clinical practice guidelines. With modern surgery and anesthesia, breast surgeries are considered safe and is usually associated with very low complication rates, regardless of extent of surgery. However, oncoplastic surgery and management of the axilla can be tailored based on patients’- and disease-related factors. Most of chemotherapeutic agents, along with targeted therapy and anti-Human epidermal growth factor receptor-2 (HER2) drugs can be safely given for older patients, however, dose adjustment and close monitoring of potential adverse events might be needed. The recently introduced cyclin-D kinase (CDK) 4/6-inhibitors in combination with aromatase inhibitors (AI) or fulvestrant, which changed the landscape of breast cancer therapy, are both safe and effective in older patients and had substituted more aggressive and potentially toxic interventions. Despite its proven efficacy, adjusting or even omitting adjuvant radiation therapy, at least in low-risk older patients, is safe and frequently practiced. In this paper, we review existing data related to breast cancer management among older patients across the continuum; from resection of the primary tumor through adjuvant chemotherapy, radiation and endocrine therapy up to the management of recurrent and advanced-stage disease.

Long term outcome data from the EORTC 75111-10114 ETF/BCG randomized phase II study: Pertuzumab and trastuzumab with or without metronomic chemotherapy for older patients with HER2-positive metastatic breast cancer, followed by T-DM1 after progression

INTRODUCTION

Older patients are at higher risk of chemotherapy-induced toxicity, raising interest in less toxic anti-HER2 regimens for older persons with HER2-positive (HER2+) metastatic breast cancer (MBC).

PATIENTS AND METHODS

This phase II study randomized (1:1) patients with HER2+ MBC, aged 70+ or frail 60+, to first line chemotherapy with metronomic oral cyclophosphamide (M) + Trastuzumab (T) and Pertuzumab (P) or TP alone. T-DM1 was offered in case of progression.

RESULTS

In total, 39 and 41 patients were randomized to TP and TPM arm respectively. Median follow-up is 54.0 months. 24-month PFS was 18.7% (95% CI 8.2-32.4) and 28.7% (95% CI 15.8-43.0), respectively. A total of 49 (61.3%) patients died of whom 37 (75.5%) from disease progression; number of deaths per arm was 27 (69.2%) for TP and 22 (53.7%) for TPM. There was no significant difference in OS between the two arms (median OS TP vs TPM: 32.1 vs 37.5 months, p 0.25). Among the 40 patients who have started T-DM1 after disease progression on TP/TPM, PFS rate at 6 months after start of T-DM1 was 43.6% (95% CI: 27.7-58.5) and grade 3 or higher AE occurred in 18 pts (45%).

CONCLUSIONS

Metronomic chemotherapy-based dual blockade (TPM), followed by T-DM1 after progression, provides an active and relatively well tolerated treatment option in an older/frail HER2+ MBC population, with a median survival of over 3 years. Nevertheless, the majority of this older/frail population died from breast cancer, highlighting the need for well tolerated and efficacious treatments in these patients.

Sociodemographic disparities in molecular testing for breast cancer

PURPOSE

Molecular testing is a critical component of breast cancer care used to identify the presence of estrogen and/or progesterone receptors (jointly hormone receptors-HRs) and the expression of human epidermal growth factor 2 (HER2) on a tumor. Our objective was to characterize trends and predictors of lack of molecular testing among female breast cancer patients overall and by sociodemographic characteristics.

METHODS

We examined data on female breast cancer patients diagnosed between 2010 and 2016 from Surveillance Epidemiology and End Results-18. Joinpoint regression analyses assessed annual percent change (APC) in lack of ER, PR, or HER2 testing. Multivariable, multilevel logistic regression models identified factors associated with lack of molecular testing.

RESULTS

A nominally lower proportion of rural patients did not receive molecular testing (e.g., 1.8% in rural vs. 2.3% in urban for HER2). For all tests, a higher proportion of Hispanic and non-Hispanic Black women were not tested. Across all characteristics, improvement in testing was noted, although disparities among groups remained. For example, lack of HER2 testing improved from 3.2 to 1.7% in White patients (APC = - 10.05) but was consistently higher in Black patients 3.9 to 2.3% (APC = - 8.21). Multivariable, multilevel models showed that older, non-Hispanic Black, and unpartnered women were at greater odds of not receiving molecular testing.

CONCLUSIONS

While lack of molecular testing of breast cancer patients is relatively rare, racial/ethnic, insurance status, and age-related disparities have been identified. To reduce testing and downstream treatment and outcome disparities, it is imperative for all breast cancer patients to receive molecular testing.

Surgical under-treatment of older adult patients with cancer: A systematic review and meta-analysis

BACKGROUND

Older patients with cancer often have lower surgery rates and survival than younger patients, but this may reflect surgical contraindications of advanced disease, comorbidities, and frailty - and not necessarily under-treatment.

OBJECTIVES

This review aims to describe variations in surgery rates and observed or net survival among younger (<75) and older (≥75) patients with breast, lung and colorectal cancer, while taking account of pre-existing health factors, in order to understand how under-treatment is defined and estimated in the literature.

METHOD

MEDLINE, EMBASE, Web of Science and PubMed databases were searched for studies reporting surgery rates and observed or net survival among younger and older patients with breast, lung, and colorectal cancer. Study quality was assessed using the Newcastle Ottawa Scale, and random effects meta-analyses were used to combine study results. The I-squared statistic and subgroup analyses were used to assess heterogeneity.

RESULTS

Thirty relatively high-quality studies of patients with breast (230,200; 71.9%), lung (77,573; 24.2%), and colorectal (12,407; 3.9%) cancers were identified. Compared to younger patients, older patients were less likely to receive surgical treatment for 1) breast cancer after adjusting for comorbidity, performance status (PS), functional status and patient choice, 2) lung cancer after accounting for stage, comorbidity, PS, and 3) colorectal cancer after adjusting for stage, comorbidity, and gender. The pooled unadjusted analyses showed lower surgery receipt in older patients with breast (odds ratio [OR] 0.31, 95% confidence interval [CI] 0.13-0.78), lung (OR 0.54, 95% CI 0.39-0.75), and colorectal (OR 0.59, 95% CI 0.51-0.68) cancer. In separate analyses, older patients with breast, lung and colorectal cancer had lower observed and net survival, compared to younger patients.

CONCLUSIONS

Lower surgery rates in older patients may contribute to their poorer survival compared to younger patients. Future research quantifying under-treatment should include necessary clinical factors, patient choice, patient's quality of life and a statistically-robust approach, which will demonstrate how much of the survival deficit in older patients is due to their receiving lower surgery rates.

Short- and long-term recurrence of early-stage invasive ductal carcinoma in middle-aged and old women with different treatments

Most new cases and the highest mortality rates of breast cancer occur among middle-aged and old women. The recurrence rate of early-stage invasive ductal carcinoma (IDC) among women aged ≥ 50 years and receiving different treatments remains unclear. Therefore, this study was conducted to determine these rates. We used Surveillance, Epidemiology, and End Results (SEER) data for this nationwide population-based cohort study. All women aged ≥ 50 years and diagnosed with early-stage IDC between 2000 and 2015 were identified and divided into three treatment groups, namely, breast conservation therapy (BCT), mastectomy alone (MAS), and mastectomy with radiation therapy (MAS + RT). The recurrence rates of IDC among these groups were then compared. The BCT group had a lower short-term recurrence risk than the MAS and MAS + RT groups (hazard ratio [HR]: 1.00 vs. 2.90 [95% CI 1.36–2.66] vs. 2.07 [95% CI 0.97–4.44]); however, the BCT group also had a higher long-term recurrence risk than MAS and MAS + RT groups (HR 1.00 vs. 0.30 [95% CI 0.26–0.35] vs. 0.43 [95% CI 0.30–0.63]). The high long-term recurrence rate of the BCT group was especially prominent at the 10- and 15-year follow-ups. The results provide valuable evidence of the most reliable treatment strategy for this population. Further studies including more variables and validation in other countries are warranted to confirm our findings.

Metastasis patterns and prognosis of octogenarians with metastatic breast cancer: A large-cohort retrospective study

Background

Breast cancer may differ biologically in patients aged over 80 years. The objective of the current study was to analyze the metastasis patterns and prognosis of elderly patients with metastatic breast cancer (MBC) and compare it to patients of other ages.

Methods

The Surveillance, Epidemiology, and End Results (SEER) database was utilized to select MBC patients from 2010 to 2015. Chi-squared test was used to compare clinicopathological characteristics among different aged groups. The Kaplan-Meier method and multivariate Cox model were utilized for survival analysis.

Results

A total of 10479 MBC patients were included, among which 1036 (9.9%) patients were aged over 80 years. Compared with other aged group, the elderly patients tended to have a higher proportion of HR+/Her2- subtype, white race, lower tumor differentiation, and receive less treatment, including surgery, chemotherapy and radiotherapy (P< 0.001). MBC patients with different age presented with distinctive metastatic patterns. The older patients were more likely to have lung metastasis, but less likely to have bone, brain, liver and multiple sites metastasis than the younger group (P <0.001). The proportion of TNBC subtype increased substantially in the older patients with brain metastasis, compared to the younger and middle-aged group. The old age was demonstrated to significantly associate with worse prognosis of MBC patients. Additionally, our findings also showed that older MBC patients could achieve dramatical overall survival benefit from surgery (HR = 0.58; P <0.001) and chemotherapy (HR = 0.59; P <0.001), but not the radiotherapy (HR = 0.96; P = 0.097).

Conclusion

The elderly MBC patients presented with distinctive metastatic patterns, clinical characteristics, and prognostic outcomes compared with younger patients. Our findings could assist clinicians in making appropriate therapeutic decision.

Adjuvant Treatment of Elderly Breast Cancer Patients: Offer the Best Chances of Cure

Background

Breast cancer remains the most common cancer in women and a leading cause of death. Elderly people have a higher incidence of breast cancer since it increases with age. Furthermore, the extended life expectancy and advances in imaging techniques have led to an increased number of cases. Guidelines concerning the management of this specific age group are rare, mainly due to underrepresentation of seniors in clinical trials. Moreover, increased frailty, comorbidities, and a poor performance status make it complex to determine the best therapeutic approach.

Summary

In this review, we attempt to summarize the current literature and aim to provide specific approaches and recommendations for prompt diagnosis, treatment, and management of breast cancer in the elderly.

Key Messages

The establishment of applicable protocols is imperative and efforts are being made in this direction. A careful geriatric assessment and adequate consultation should be the standard of care and patient's preferences should always be considered.

Analysis of the Effect of Trastuzumab Combined with Docetaxel on Serum Tumor Markers in the Treatment of HER-2 Positive Breast Cancer and Factors Influencing Therapeutic Efficacy

Objective

To explore the influence of trastuzumab (TZ) combined with docetaxel (DTX) on serum tumor markers (TMs) in the treatment of human epidermal growth factor receptor 2-positive (HER-2+) breast cancer (BC) and to analyze the factors influencing therapeutic efficacy.

Methods

Ninety-six patients with HER-2+ BC treated in the First Affiliated Hospital of Anhui University Of Science and Technology from January 2019 to December 2020 were selected. According to different treatment plans, the patients were divided into two arms with 48 cases each. The control group (CG) was treated with DTX, and the research group (RG) was given TZ combined with DTX (TZ+DTX). The two arms were compared regarding the following aspects: curative effects, adverse reaction, alterations of TMs and inflammatory factors (IFs), and quality of life. Logistic regression analysis was performed to analyze the factors affecting the efficacy of patients.

Results

After treatment, the TMs carcinoembryonic antigen (CEA), carbohydrate antigen (CA)125 and CA15-3 were significantly lower in RG compared with CG. The levels of IFs C-reactive protein (CRP) and tumor necrosis factor-α (TNF-α) were also lower in CG. The overall response rate and the Karnofsky performance status (KPS) score were significantly higher in RG. No evident difference was observed in the total incidence of adverse reactions between the two arms. The high expression of CEA, CA125 and CA15-3 as well as DTX monotherapy increased the risk of adverse prognosis.

Conclusion

TZ+DTX can effectively improve the clinical efficacy of HER-2+ BC patients and reduce their levels of serum TMs and IFs.

Breast Cancer in Women Over 65 years- a Review of Screening and Treatment Options

Breast cancer is becoming increasingly prevalent in the women greater than 65 years of age. Most tumors are hormone receptor-positive in this group. Breast cancer screening recommendations for older women should be tailored based on life expectancy. Early stage breast cancer should be treated with conservative surgery followed by adjuvant endocrine therapy in HR+ patients. Primary endocrine therapy is a low-risk option for those with limited life expectancy. Adjuvant radiation therapy can be avoided in early stage, low-risk cancers. Evaluation should include comprehensive geriatric assessment. Treatment with less cytotoxic chemotherapy, HER-2 targeted therapies, and other biomarker-driven, molecularly targeted therapies should be sought whenever possible.

Population-based analysis of non-operative management and treatment patterns in older women with estrogen receptor-positive breast cancer

PURPOSE

To examine the proportion of older women with ER + HER2- breast cancer receiving non-operative management versus surgery, and to evaluate the use of axillary staging and adjuvant radiation in this population.

METHODS

We queried the SEER database to identify all women aged 70 years or older with stage I-III ER + HER2- invasive breast cancer diagnosed between 2010 and 2016. We evaluated trends in non-operative management, breast surgery, axillary staging, and adjuvant radiation according to age at diagnosis.

RESULTS

We identified 57,351 older women with ER + HER2- disease. Overall, 3538 (6.2%) of the cohort underwent non-operative management, 38,452 (67.0%) underwent breast-conserving surgery (BCS), and 15,361 (26.8%) underwent mastectomy. The proportion of patients undergoing non-operative management increased from 2.8% among 70-74-year-old women to 30.1% in those ≥ 90 years old (p < 0.001). In 53,813 women who underwent surgery, 36,850 (68.5%) underwent sentinel lymph node biopsy, while 10,861 (20.2%) underwent axillary lymph node dissection. Subgroup analysis of 29,032 older women undergoing BCS for stage I ER + HER2- breast cancer revealed a 14.2% rate of omission of axillary staging, increasing from 5.3% in those 70-74 years to 67.6% in those ≥ 90 years old (p < 0.001). Receipt of adjuvant radiation occurred in 63.3% of older women following BCS and 18% post-mastectomy, with similar trends towards omission in older age groups.

CONCLUSION

Primary breast surgery remains the dominant management strategy for the majority of older women with ER + HER2- breast cancer. Omission of axillary staging and adjuvant radiation are used in a minority of eligible women undergoing breast conservation for early-stage disease.

Suboptimal therapy following breast conserving surgery in triple-negative and HER2-positive breast cancer patients

PURPOSE

To assess potential disparities in guideline-concordant care delivery among women with early-stage triple-negative and HER2-positive breast cancer treated with breast conserving therapy.

METHODS

Women ≥ 40 years old diagnosed with pT2N0M0 triple-negative or HER2-positive breast cancer treated with primary surgery and axillary staging between 2012 and 2017 were identified using the National Cancer Database (NCDB). The primary outcome was receipt of adjuvant systemic therapy and radiation concordant with current guidelines. Multivariable log-binomial regression was used to assess the prevalence of optimal therapy use across patient and cancer characteristics. Kaplan-Meier curves were used to assess 5-year overall survival. Multivariable Cox proportional hazards regression was used to compare the impact of optimal therapy on 5-year mortality.

RESULTS

11,785 women were included with 7,843 receiving optimal therapy. Receipt of optimal therapy decreased with age even after adjusting for comorbidities and cancer characteristics; other sociodemographic factors were not associated with differences in receipt of optimal therapy. Among patients who did not receive adjuvant systemic therapy, most were not offered the treatment (49%) or refused (40%). Overall 5-year survival was higher among women who received optimal therapy (89% [95% CI 88.0-89.3] vs. 66% [95% CI 62.9-68.5]). Patients who received suboptimal therapy were over twice as likely to die within 5 years of their diagnosis (adjusted HR 2.44, 95% CI 2.12-2.82).

CONCLUSION

Age is the primary determinant of the likelihood of a woman to receive optimal adjuvant therapies in high-risk early-stage breast cancer. Patients who did not receive optimal therapy had significantly diminished survival.

Effects of Adjuvant Endocrine Therapy Adherence and Radiation on Recurrence and Survival Among Older Women with Early-Stage Breast Cancer

BACKGROUND

The Cancer and Leukemia Group-B 9343 (CALGB 9343) trial demonstrated that women aged ≥ 70 years with early-stage breast cancer can safely omit radiation therapy (RT) and be treated with breast-conserving surgery (BCS) and adjuvant endocrine therapy (AET) alone. AET adherence is low, leaving an undertreated cohort who may be at increased risk of recurrence and death. We hypothesized that AET adherence and adjuvant treatment choice impact recurrence and survival among CALGB 9343 eligible women.

PATIENTS AND METHODS

SEER-Medicare was used to identify CALGB 9343 eligible women who underwent BCS between 2007 and 2016. Medicare claims were used to identify AET use, and the proportion of days covered by AET was used to categorize adherent (PDC ≥ 0.80) versus nonadherent patients (PDC < 0.80). Recurrence-free, cancer-specific, and overall survival were assessed using Cox proportional hazards models.

RESULTS

In total, 10,719 women were identified, of whom 780 (7.3%) underwent BCS alone, 1490 (13.9%) underwent BCS + RT, 1663 (15.5%) underwent BCS + AET, and 6786 (63.3%) had BCS + RT + AET. Among women treated with BCS + AET, adherent patients had lower recurrence than did nonadherent patients (HR = 0.65, 95% CI: 0.50-0.85). With respect to adjuvant treatment combinations, there was no recurrence difference between the BCS + RT + AET group and BCS + AET group (HR = 0.81, 95% CI: 0.54-1.21). There was equivalent cancer-specific but worse overall survival in the BCS + AET group versus the BCS + AET + RT group.

CONCLUSIONS

While BCS + RT + AET may represent overtreatment for some, AET nonadherent women who omit RT are at risk for worse outcomes. Treatment decisions regarding RT omission should be tailored to the individual patient, taking into consideration the chances of AET nonadherence and the patients' own risk tolerance.

Variations in intrinsic breast cancer characteristics in screen-detected breast cancer patients aged between 45 and 69 and above the age of 70

BACKGROUND

Increasing age is a well-recognized risk factor for breast cancer. With an increase in life expectancy of women, more older patients are diagnosed with breast cancer. This study aimed to identify the variations in breast cancer attributes and mortality in different age groups in New Zealand.

METHODS

This was a retrospective study of data from the Auckland Breast Cancer Register between 1 June 2000 and 28 February 2017. Patients who were diagnosed through Breast Screen were included. Group A included those aged between 45 and 69 years. Group B included individuals with an age of 70 years or above.

RESULTS

From June 2000 to February 2017, a total of 6304 new cases of new breast cancer were diagnosed through Auckland Breast Screen, with 5788 patients in group A and 516 patients in group B. Group B was more likely to have the lower grade invasive cancers, with fewer grade 3 cancers. Oestrogen receptor positivity was more pronounced in group B, along with progesterone receptor positivity. Conversely, HER-2 receptor was less likely to be positive in group B. There was a significantly higher breast cancer-related mortality in group B (6.0% versus 2.7%). Mortality related to other causes was also much higher in group B as compared to that in group A (12.8% versus 2.5%).

CONCLUSION

Women aged 70 years or above generally tend to have a more favourable type of breast cancer, with a lower tumour grade, oestrogen and progesterone receptor positivity, and lower rate of HER-2 overexpression.

The Evolving Complexity of Treating Hormone Receptor-Positive, Human Epidermal Growth Factor Receptor-2 (HER2)-Negative Breast Cancer: Special Considerations in Older Breast Cancer Patients-Part II: Metastatic Disease

Breast cancer is a disease of aging, and the incidence of breast cancer is projected to increase dramatically as the global population ages. The majority of breast cancers that occur in older adults are hormone-receptor positive, human epidermal growth factor receptor-2 (HER2)-negative phenotypes, with favorable tumor biology; yet, because of underrepresentation in clinical trials, less evidence is available to guide the complex care for this population. Providing care for older patients with metastatic breast cancer, with coexisting medical conditions, increased risk of treatment toxicity, and frailty, remains a clinical challenge in oncology. In this review, we provide an overview of the current evidence from clinical trials and subanalyses of older adults with hormone receptor-positive, HER2-negative metastatic breast cancer, highlighting data on the safety and efficacy of oral therapies, including endocrine therapy alone or in combination with cyclin-dependent kinase (CDK) 4/6 inhibitors, phosphatidylinositol 3-kinase (PI3K) inhibitors, and mammalian target of rapamycin (mTOR) inhibitors. In addition, we note the significant underrepresentation of older and frail adults in these studies. Current and future directions in research for this special population, in order to address significant knowledge gaps, include the need to improve long-term adherence to hormonal and targeted therapy, prospective clinical trials that capture clinical and biological aging endpoints, and the need for a multidisciplinary approach with integration of geriatric and oncology principles.

Oncotype DX Breast Recurrence Score Distribution and Chemotherapy Benefit Among Women of Different Age Groups With HR-Positive, HER2-Negative, Node-Negative Breast Cancer in the SEER Database

Objective: To explore the distribution of Oncotype DX Breast Recurrence Score (RS), the proportion of receiving chemotherapy, and the relationship between RS and chemotherapy benefit according to detailed age groups in women with hormone receptor-positive, human epidermal growth factor receptor 2-negative, node-negative (HR+/HER2−/N0) breast cancer.

Methods: This was an extensive, comprehensive, population-based retrospective study. Data on individuals with breast cancer were obtained from the Surveillance, Epidemiology, and End Results (SEER) Program. The cohort was divided into five groups by age (≤ 35, 36–50, 51–65, 66–80, >80 years). RS distribution and chemotherapy proportion among different age groups were analyzed, and the overall survivals between patients receiving chemotherapy and those not/unknown were compared in each age group.

Results: The study cohort comprised 49,539 patients and the largest age group was 51–65 years. The percentage of patients with low-risk RS (0–10) increased with age, whereas those with intermediate-risk RS (11–25) decreased with age (except for the group of 36–50 years, which had the highest rate of intermediate-risk RS). The age group ≤35 years has the greatest rate of high-risk RS (26–100). The proportion of receiving chemotherapy decreased with age in all RS risk categories. Overall survival was benefited by chemotherapy only in the age group of 66–80 years with intermediate- and high-risk RS, and chemotherapy seemed to do more harm than good for patients older than 80 years.

Conclusions: In the present study, we identified the distribution of RS, the proportion of receiving chemotherapy, and the relationship between RS and chemotherapy benefit according to a detailed age grouping for women with HR+/HER2−/N0 breast cancer, which may help in making individualized clinical decisions.

Breast cancer in the oldest old (≥ 89 years): Tumor characteristics, treatment choices, clinical outcomes and literature review

INTRODUCTION

Risk of breast cancer increases with age and very few data are available in patients older than 89.

METHODS

A retrospective analysis on patients aged 89 and older treated between 2008 and 2019 at our certified breast center. The aim was to analyze clinical characteristics, decision-making, treatment, outcomes and open questions regarding this subpopulation for which there is a lack of guidelines.

RESULTS

58 patients included. Tumor characteristics were analyzed, 85% patients underwent surgery of which 44% had a mastectomy. The median follow-up and overall survival were 20 and 76 months, respectively.The median survival of metastatic and non-metastatic patients were 14 and 50 months, respectively. Most patients did not receive any adjuvant treatment and among these 14% had a relapse.

CONCLUSIONS

Elderly patients should not be under or over-treated because of their age; they represent a large heterogeneous group deserving a sub-stratification for a better tailored treatment.

The 8-Year Management of an Older Breast Cancer Patient by Non-surgical Primary Therapies and Minimized Surgery: A Case Report

A 74-year-old woman presented with a palpable lesion in her right breast. At the time of her visit, she was taking medications for diabetes, hypertension, tremors, tinnitus, and lumbago. She was also caring for her husband, who had dementia. Imaging studies revealed another lesion in addition to the palpable mass. A core biopsy of the palpable mass confirmed invasive ductal carcinoma. Surgery was recommended to remove both masses. However, the patient refused the operation due to her comorbidities and her husband's nursing needs. A modified treatment process, including non-surgical primary therapies, minimized surgery, and close follow-up, for 8 years proved successful. This report focuses on the points to consider in the treatment and management of older patients with breast cancer.

POLARIS: a prospective, multicenter, noninterventional study assessing palbociclib in hormone receptor-positive advanced breast cancer

This report describes the rationale, purpose and design of the POLARIS study. POLARIS is an ongoing noninterventional, prospective, multicenter study. Female and male patients in the USA and Canada diagnosed with hormone receptor-positive/HER2-negative metastatic breast cancer were enrolled in the study and treated with the cyclin-dependent kinase 4/6 inhibitor palbociclib when hormone receptor-positive/HER2-negative metastatic breast cancer was deemed to be indicated by their physician. The study will provide real-world data on palbociclib prescribing and treatment patterns in routine clinical practice, associated clinical outcomes, treatment sequencing in the advanced/metastatic setting, patient quality of life and geriatric-specific assessments. The tumor genomic landscape in relation to clinical outcomes will be explored. POLARIS will identify benefits and side effects of palbociclib across multiple lines of therapy and in discrete subsets of patients. Clinical Trial Registration: NCT03280303 (ClinicalTrials.gov).

Breast Cancer in Patients 80 Years-Old and Older

Objective

Breast cancer is the most common cancer in women and one in ten patients affected are over age 80. However, this age group is mostly excluded from clinical trials and data to inform their care is sparse.

Materials and Methods

Medical records of all patients aged 80 years-old and older diagnosed and treated for breast cancer in a single center over a six-year period were retrospectively reviewed. A cohort of patients aged 65 to 75 treated for breast cancer at the same center during the same period was also reviewed for comparison.

Results

Patients in the 80 and over age group were commonly diagnosed with stage II or III disease (39.2%) compared to younger patients who were diagnosed more commonly (61.6%) with stage I disease. Sub-types of breast cancer had a similar representation in the two groups. Hormonal therapy was used equally in the two groups, but significantly fewer patients in the 80 and over age group had radiation therapy and chemotherapy as part of their treatment. Despite these differences, recurrence rates were not significantly different between the two groups.

Conclusion

Individualized treatments taking into consideration the patient's general status, comorbidities and life expectancy are feasible in the older breast cancer population and result in outcomes similar to those of younger patients in the short and intermediate terms.

A systematic review and meta-analysis of clinician-reported versus patient-reported outcomes of radiation dermatitis

Radiation dermatitis is a common adverse effect of radiotherapy (RT) in breast cancer patients. Although radiation dermatitis is reported by either the clinician or the patient, previous studies have shown disagreement between clinician-reported outcomes (CROs) and patient-reported outcomes (PROs). This review evaluated the extent of discordance between CROs and PROs for radiation dermatitis. Studies reporting both clinician and patient-reported outcomes for external beam RT were eligible. Nine studies met the inclusion criteria for the systematic review, while 8 of these studies were eligible for inclusion in a meta-analysis of acute and late skin toxicities. We found an overall agreement between CROs and PROs of acute skin colour change, fibrosis and/or retraction, and moist desquamation (p > 0.005). Reporting of late breast pain, breast edema, skin colour change, telangiectasia, fibrosis and/or retraction and induration/fibrosis alone (p > 0.005) were also in agreement between clinicians and patients. Our meta-analysis revealed a greater reporting of acute breast pain by patients (RR = 0.89, 95% CI 0.87-0.92, p < 0.001), greater reporting of acute breast edema by physicians (RR = 1.80, 95% CI 1.65-1.97, p < 0.001) and a greater reporting of late breast shrinkage by patients (RR = 0.61, 95% CI 0.44-0.86, p = 0.005). However, our review was limited by the discrepancies between PRO and CRO measurement tools as well as the absence of standard time points for evaluation of radiation dermatitis. Given potential discrepancies between CROs and PROs, both measures should be reported in future studies. Ultimately, we advocate for the development of a single tool to assess symptoms from both perspectives.

Open Wounds and Healed Scars: A Qualitative Study of Elderly Women's Experiences With Breast Cancer

BACKGROUND

Breast cancer is more prevalent among women 60 years or older than among women younger than 60 years. However, we know much more about the breast cancer experiences of younger women than of older women. Such knowledge is important, for example, to guide treatment decisions or to provide psychosocial care.

OBJECTIVE

The aim of this study was to gain insight into the experiences of women with breast cancer 70 years or older.

METHODS

Semistructured interviews were conducted with 21 older patients with breast cancer in the Netherlands. We used open coding and affinity diagramming to evoke the themes reflecting the experiences of these women.

RESULTS

Four themes emerged from the data: living through and coping with breast cancer, information exchange and informed choice, support experiences, and impact on daily life. Getting breast cancer took some women by surprise. However, older women with breast cancer coped fairly well and were satisfied with the support they received, especially from oncology nurses. Disturbing treatment adverse effects and changes in appearance, comorbid diseases, lack of clear information, and/or an unsupportive environment complicated their living with breast cancer.

CONCLUSIONS

Even though many older women with breast cancer handle their disease rather well, some women do encounter difficulties. Lack of support, comorbid diseases, and treatment adverse effects warrant extra attention.

IMPLICATIONS FOR PRACTICE

Nurses' close attention to women at risk and early intervention could help relieve individual suffering, while taking these womens' strengths into account can enhance self-management.

Age-related disparities in older women with breast cancer

Improvements in breast cancer (BC) mortality rates have not been seen in the older adult community, and the fact that older adults are more likely to die from their cancer than younger women establishes a major health disparity. Studies have identified that despite typically presenting with more favorable histology, older women present with more advanced disease, which may be related in part to delayed diagnosis. This is supported by examination of screening practices in older adults. Older women have a worse prognosis than younger women in both early stage disease, and more advanced and metastatic disease. Focus on the treatment of older adults has often concentrated on avoiding overtreatment, but in fact undertreatment may be one reason for the age-related differences in outcomes, and treatments need to be individualized for every older adult, and take into account patient preferences and functional status and not chronologic age alone. Given the aging population in the US, identifying methods to improve early diagnosis in this population and identify additional factors will be important to reducing this age-related disparity.

The Influence of Age on the Histopathology and Prognosis of Atypical Breast Lesions

BACKGROUND

Although several prognostic variables and risk factors for breast cancer are age-related, the association between age and risk of cancer with breast atypia is controversial. This study aimed to compare the type of breast atypia and risk of underlying or subsequent breast cancer by age.

METHODS

Adult women with breast atypia (atypical ductal hyperplasia, atypical lobular hyperplasia, and lobular carcinoma in situ) at a single institution from 2008 to 2017 were stratified by age at initial diagnosis: <50 y, 50-70 y, and >70 y. Regression modeling was used to estimate the association of age with risk of underlying carcinoma or subsequent cancer diagnosis.

RESULTS

A total of 530 patients with atypia were identified: 31.1% < 50 y (n = 165), 58.1% 50-70 y (n = 308), and 10.8% > 70 y (n = 57). The proportion of women with atypical ductal hyperplasia steadily increased with age, compared with atypical lobular proliferations (P = 0.04). Of those with atypia on needle biopsy, the overall rate of underlying carcinoma was 17.5%. After adjustment, older age was associated with a greater risk of underlying carcinoma (odds ratio: 1.028, 95% confidence interval: 1.003-1.053; P = 0.03). Of those confirmed to have atypia on surgical excision, the overall rate of a subsequent cancer diagnosis was 15.7%. Age was not associated with a long-term risk for breast cancer (P = 0.48) or the time to a subsequent diagnosis of carcinoma (log-rank P = 0.41).

CONCLUSIONS

Although atypia diagnosed on needle biopsy may be sufficient to warrant surgical excision, older women may be at a greater risk for an underlying carcinoma, albeit the long-term risk for malignancy associated with atypia does not appear to be affected by age.

Comprehensive Geriatric Assessment as a Versatile Tool to Enhance the Care of the Older Person Diagnosed with Cancer

The comprehensive geriatric assessment (CGA) is a versatile tool for the care of the older person diagnosed with cancer. The purpose of this article is to detail how a CGA can be tailored to Ambulatory Geriatric Oncology Programs (AGOPs) in academic cancer centers and to community oncology practices with varying levels of resources. The Society for International Oncology in Geriatrics (SIOG) recommends CGA as a foundation for treatment planning and decision-making for the older person receiving care for a malignancy. A CGA is often administered by a multidisciplinary team (MDT) composed of professionals who provide geriatric-focused cancer care. CGA can be used as a one-time consult for surgery, chemotherapy, or radiation therapy providers to predict treatment tolerance or as an ongoing part of patient care to manage malignant and non-malignant issues. Administrative support and proactive infrastructure planning to address scheduling, referrals, and provider communication are critical to the effectiveness of the CGA.

The use of contralateral prophylactic mastectomy among elderly patients in the United States

PURPOSE

Previous studies have reported increased rates of contralateral prophylactic mastectomy (CPM) in the United States among women with unilateral breast cancer. These trends have primarily focused on younger breast cancer patients. Given the growing aging population in the United States, we sought to determine whether CPM use is also increasing in elderly patients.

METHODS

This population-based study identified patients in the surveillance epidemiology and end results (SEER) data. We determined the rate of CPM as a proportion of all surgically treated patients and as a proportion of all mastectomies. We compared the unadjusted CPM rates over the study period using the Cochrane-Armitage test for trend. We used a logistic regression model to test for the factors associated with CPM utilization.

RESULTS

We identified 261,281 patients ≥ 65 years who underwent surgical treatment for breast cancer. For all patients treated with surgery for invasive breast cancer, the use of CPM increased from 1 in 2004 to 3% in 2014 (200% increase). Among mastectomy patients, the use of CPM increased from 3 in 2004 to 7% in 2014 (133% increase). Young age, non-Hispanic white race, lobular histology, higher grade, increased stage, negative lymph node status, and recent year of diagnosis were significantly associated with increased CPM rates.

CONCLUSIONS

For elderly patients the use of CPM has continued to increase in the United States. These observations warrant concern in light of increasing evidence that CPM does not improve oncological outcomes and is associated with increased morbidity in older patients.

Treatment strategies and predicting prognoses in elderly patients with breast cancer

Objective

The prevalence of breast cancer in elderly women (older than 80 years) is expected to rise more dramatically than its incidence. In this study, we evaluated the evidence for treatment guidelines for elderly breast cancer patients.

Patients and methods

All included patients were enrolled from 2010 to 2013 from the Surveillance, Epidemiology, and End Results (SEER) database. The Akaike information criterion (AIC) and Harrell’s C statistic were used to perform comparisons. In addition, a propensity score analysis was used to avoid bias caused by data selection criteria. Prognostic factors were selected as nomogram parameters to develop a model to predict survival.

Results

A total of 16998 patients included in the SEER database from 2010 to 2013 had breast cancer and fulfilled the study criteria. Of whom, 13007 patients underwent surgery. Overall survival and cancer-specific survival were significantly better in patients who underwent surgery and/or radiotherapy than in those who did not (P<0.001). In addition, a nomogram system with a C index of 0.83 and an AIC index of 11112.85 was better able to predict prognoses and estimate cancer-specific survival in elderly patients with breast cancer.

Conclusion

A localized surgical approach might provide better results in elderly breast cancer patients. However, radiotherapy improved cancer-specific survival and overall survival in these patients. In addition, a prognostic nomogram directly quantified patient risk by accounting for various prognostic factors without forming risk groups and was better able to estimate cancer-specific survival.

Breast cancer treatment in women over the age of 80: A tailored approach

Breast cancer treatment in women over the age of 80 remains a complex issue due to pre-existing comorbidities, therapy-related toxicities, and the lack of evidence-based data in this population, leading to both overtreatment and under treatment. The average life expectancy of an 80-year-old woman is 9.7 years and chronologic age alone should not be a factor in withholding therapy. Women over age 80 should be treated on an individual basis, taking into account their overall health and life expectancy, their risk of dying from breast cancer versus other causes, and the benefits versus toxicities of therapies for their tumor. Invaluable online tools are readily available to easily assess life expectancy (ePrognosis), as well as the absolute survival benefits for every tumor type and stage in individual patients (PREDICT, Ajuvant!). This information should be presented to the patient so that they are able to make an informed decision based on their goals, wishes and quality of life. Vulnerable patients should not be bullied or scared into taking unwanted or unnecessary treatments.

Breast cancer in octogenarian. Are we doing our best? A population-registry based study

BACKGROUND

The number of old people with breast cancer is estimated to increase during the next years in developed countries. However, management of breast cancer in octogenarians is not well established. The main objective was to evaluate if patients older than 80 years with breast cancer are receiving the most convenient treatment by using a population registry cancer analysis.

PATIENTS AND METHODS

A retrospective analysis of a population cancer registry was designed. Data were retrieved from the Castellon Cancer Registry (Valencian Community, Spain). Patient records were analyzed from January 1, 1995 to December 31, 2013. Two groups were defined: group A, <80 years; and group B, >= 80 years. Survival analyses were sequentially performed into three phases. First, a non-adjusted Kaplan Meier analysis was conducted. For the second survival analyses, Cox's proportional hazards model of Overall survival was used adjusting for condensed-TNM stage and adjuvant treatments. Finally, the third specific adjustment was carried out adding information of life expectancy by age for Spanish women, corresponding to year 2008 with condensed-TNM stage and Propensity Score variable, as an approximation to relative or disease-specific survival.

RESULTS

The total number of included patients was 1304. Women ≥80 years presented a more extended disease, larger tumors and less in situ carcinomas. A lower proportion of women ≥80 years received adjuvant therapies. In the absence of any adjustment of results, the overall survival in women ≥80 years was poorer than in younger patients (median of 14.1 years for <80y vs. 5.7 years for ≥80y), the crude HR was 4.6 (95% CI: 2.9-7.5) p < 0.001. For second survival analysis, the HR was 2.5 (95% CI: 1.8-3.5) p < 0.001. After the third adjustment the HR was 1.7 (95% CI: 1.2-2.4) p = 0.004.

CONCLUSIONS

Octogenarians with operable breast cancer are receiving suboptimal treatments, which can have repercussions on survival. New studies are required to identify a subgroup of women age ≥80 years who may benefit from more aggressive treatment and a population of older women on the basis of tumor characteristics, comorbidities and life expectancy who may not need as aggressive treatment.

Specific Aspects of Breast Cancer Therapy of Elderly Women

Breast cancer is the leading cause of death among women, and its incidence increases with age. The average age at diagnosis is 61 years, and the majority of deaths occurs after the age of 65 years. Optimal approach to elderly women with breast cancer is still a major challenge. Elderly patients with cancer should have at least a brief geriatric assessment to detect potentially treatable problems not always adequately evaluated by the oncologists. Therapeutic nihilism should be avoided and effective treatment provided, unless there are compelling reasons against it. Sharing the care for the patient with geriatricians or primary care physicians trained in geriatrics should be considered for all vulnerable and frail elderly patients.
