Navigating financial toxicity in patients with cancer: A multidisciplinary management approach.

Approximately one-half of individuals with cancer face personal economic burdens associated with the disease and its treatment, a problem known as financial toxicity (FT). FT more frequently affects socioeconomically vulnerable individuals and leads to subsequent adverse economic and health outcomes. Whereas multilevel systemic factors at the policy, payer, and provider levels drive FT, there are also accompanying intervenable patient-level factors that exacerbate FT in the setting of clinical care delivery. The primary strategy to intervene on FT at the patient level is financial navigation. Financial navigation uses comprehensive assessment of patients' risk factors for FT, guidance toward support resources, and referrals to assist patient financial needs during cancer care. Social workers or nurse navigators most frequently lead financial navigation. Oncologists and clinical provider teams are multidisciplinary partners who can support optimal FT management in the context of their clinical roles. Oncologists and clinical provider teams can proactively assess patient concerns about the financial hardship and employment effects of disease and treatment. They can respond by streamlining clinical treatment and care delivery planning and incorporating FT concerns into comprehensive goals of care discussions and coordinated symptom and psychosocial care. By understanding how age and life stage, socioeconomic, and cultural factors modify FT trajectory, oncologists and multidisciplinary health care teams can be engaged and informative in patient-centered, tailored FT management. The case presentations in this report provide a practical context to summarize authors' recommendations for patient-level FT management, supported by a review of key supporting evidence and a discussion of challenges to mitigating FT in oncology care.

"Peace of Mind" After Mastectomy: A Scoping Review.

BACKGROUND: Many women eligible for breast conservation therapy (BCT) elect unilateral mastectomy (UM) with or without contralateral prophylactic mastectomy (CPM) and cite a desire for "peace of mind." This study aimed to characterize how peace of mind is defined and measured and how it relates to surgical choice. METHODS: Nine databases were searched for relevant articles through 8 October 2023, and data were extracted from articles meeting the inclusion criteria. RESULTS: The inclusion criteria were met by 20 studies. Most were prospective cohort studies (65%, 13/20). In the majority of the studies (72%, 13/18), Non-Hispanic white/Caucasian women comprised 80 % or more of the study's sample. Almost half of the studies used the phrase "peace of mind" in their publication (45%, 9/20), and few directly defined the construct (15%, 3/20). Instead, words representing an absence of peace of mind were common, specifically, "anxiety" (85%, 17/20), "fear" (75%, 15/20), and "concern" (75%, 15/20). Most of the studies (90%, 18/20) measured peace of mind indirectly using questionnaires validated for anxiety, fear, worry, distress, or concern, which were administered at multiple postoperative time points (55%, 11/20). Most of the studies (95%, 18/19) reported at least one statistically significant result showing no difference in peace of mind between BCT, UM, and/or CPM at their latest time of assessment. CONCLUSION: Peace of mind is largely framed around concepts that suggest its absence, namely, anxiety, fear, and concern. Existing literature suggests that peace of mind does not differ among average-risk women undergoing BCT, UM, or CPM. Shared surgical decisions should emphasize at least comparable emotional and/or psychosocial well-being between CPM and breast conservation.

Genetic testing in privately insured women with surgically treated breast cancer.

PURPOSE: Rates of BRCA1 and BRCA2 prevalence among women with breast cancer vary by age, hormone receptor status, and family history. Recommendations for genetic testing have varied between overlapping guidelines, payor coverage policies, and have evolved over time, resulting in unclear implications for adoption into routine breast cancer care. METHODS: Using a large, private insurer database, we examined rates of BRCA1/BRCA2 genetic testing in women with newly diagnosed invasive breast cancer undergoing surgery from 2015 through 2019. RESULTS: Testing increased among women 50 years or older from 26 to 38%, remained stable at 66% in both 2015 and 2019 in the under 50 population, and was slightly decreased in women under age 45 years. CONCLUSION: Among privately insured patients with breast cancer, rates are increasing in older women, but appear persistently underused in younger women.

Implications of missing data on reported breast cancer mortality.

BACKGROUND: National cancer registries are valuable tools to analyze patterns of care and clinical outcomes; yet, missing data may impact the accuracy and generalizability of these data. We sought to evaluate the association between missing data and overall survival (OS). METHODS: Using the NCDB (National Cancer Database) and SEER (Surveillance, Epidemiology, End Results Program), we assessed data missingness among patients diagnosed with invasive breast cancer from 2010 to 2014. Key variables included demographic (age, race, ethnicity, insurance, education, income), tumor (grade, ER, PR, HER2, TNM stages), and treatment (surgery in both databases; chemotherapy and radiation in NCDB). OS was compared between those with and without missing data using Cox proportional hazards models. RESULTS: Overall, 775,996 patients in the NCDB and 263,016 in SEER were identified; missing at least 1 key variable occurred for 29% and 13%, respectively. Of those, the overwhelming majority (NCDB 80%; SEER 88%) were missing tumor variables. When compared to patients with complete data, missingness was associated with a greater risk of death: NCDB HR 1.23 (99% CI 1.21-1.25) and SEER HR 2.11 (99% CI 2.05-2.18). Patients with complete tumor data had higher unadjusted OS estimates than that of the entire sample: NCDB 82.7% vs 81.8% and SEER 83.5% vs 81.7% for 5-year OS. CONCLUSIONS: Missingness of select variables is not uncommon within large national cancer registries and is associated with a worse OS. Exclusion of patients with missing variables may introduce unintended bias into analyses and result in findings that underestimate breast cancer mortality.

Ancillary Treatment Referrals and Visits After Breast Cancer Surgery in a Sociodemographically Diverse Population.

BACKGROUND: Ancillary therapies with rehabilitative, palliative, and survivorship specialists mitigate adverse effects of breast cancer surgery. Existing data suggest that patients from disadvantaged backgrounds may be less likely to receive these services. This study aimed to assess variations in ancillary provider referrals and patient visits at a high-volume urban cancer center. METHODS: Electronic health records of breast cancer surgical patients at the Yale-New Haven Health System between 2010 and 2017 were reviewed. The primary end points were postoperative referral to ancillary service providers and patient use of ancillary services (defined as attending ≥ 1 consultation). Associations between end points and demographic/disease variables were identified in uni- and multivariable logistic regression analyses. RESULTS: The study identified 5496 patients: 2288 patients (41.6%) referred to ancillary services and 1572 patients (28.6%) who attended one or more consultations. Referrals were highest among the patients with Hispanic (57.5%) or black (54.9%) ancestry, no health insurance (57.6%), lowest percentage of high school degrees for the zip code area (50.5%), and poorest median income bracket (50.7%). Associations remained significant in the multivariable analysis (p < 0.05). Minority race remained associated with referrals in analyses of each ancillary service individually. Visits to ancillary specialists were greatest among the patients with private insurance (70.7%), highest percentage of high school degrees (72.8%), highest median household income (72.2%), and Hispanic ethnicity (73.5%). Highest median household income (odds ratio [OR] 1.45; p = 0.02) and Hispanic ethnicity (OR, 1.50; p = 0.05) remained associated in the multivariable analysis. CONCLUSIONS: In a well-resourced health system serving a demographically diverse population, traditional markers of poor health care access were associated with referral for ancillary treatment after breast cancer surgery but not with utilization of ancillary treatment. Health care access remains a critical barrier to adjunctive therapies that target postoperative morbidity and elevate quality of life.

Modifiable Barriers and Facilitators for Breast Cancer Care: A Thematic Analysis of Patient and Provider Perspectives.

INTRODUCTION: We sought to examine patient and provider perspectives regarding modifiable contributors to breast cancer treatment and to assess perceptual alignment between these two groups. MATERIALS: Participants were women≥18 y with stage 0-IV breast cancer who received all oncologic care in a single health system and physicians and advanced practice providers who provided medical, radiation, or surgical oncology care for breast cancer. All completed ∼45-min semistructured interviews that were recorded and transcribed verbatim. A 5-stage approach to thematic analysis was conducted, with emergent themes and exemplar quotes placed into clinical, psychological, social/logistical, financial, and lifestyle categories using a multilevel conceptual framework. RESULTS: Eighteen patients (9 Black, 9 White, and median age 60 y) and 10 providers (6 physicians and 4 advanced practice providers) were interviewed from May to November 2018. Both patients and providers perceived suboptimal communication, parking and transportation, and competing family-caregiving responsibilities as modifiable barriers to care. Treatment costs were cited by patients as barriers that were inadequately addressed even with referrals to financial counselors, but providers did not raise the issue of cost unless prompted by patients and did not feel prepared to discuss the topic when it arose. Providers cited obesity as a barrier to treatment, a view not shared by patients. CONCLUSIONS: Several modifiable factors were recognized by both patients and providers as either promoting or detracting from treatment receipt, but there was also significant incongruence and asymmetry. Alignment of provider and patient perceptions regarding contributors to guideline-concordant care receipt could mitigate disparities in breast cancer treatment and outcomes.

Implementation of an educational intervention to improve medical student cost awareness: a prospective cohort study.

BACKGROUND: In the context of rising healthcare costs, formal education on treatment-related financial hardship is lacking in many medical schools, leaving future physicians undereducated and unprepared to engage in high-value care. METHOD: We performed a prospective cohort study to characterize medical student knowledge regarding treatment-related financial hardship from 2019 to 2020 and 2020-2021, with the latter cohort receiving a targeted educational intervention to increase cost awareness. Using Kirkpatrick's four-level training evaluation model, survey data was analyzed to characterize the acceptability of the intervention and the impact of the intervention on student knowledge, attitudes, and self-reported preparedness to engage in cost-conscious care. RESULTS: Overall, N = 142 medical students completed the study survey; 61 (47.3%) in the non-intervention arm and 81 (66.4%) in the intervention arm. Of the 81 who completed the baseline survey in the intervention arm, 65 (80.2%) completed the immediate post-intervention survey and 39 (48.1%) completed the two-month post-intervention survey. Following the educational intervention, students reported a significantly increased understanding of common financial terms, access to cost-related resources, and level of comfort and preparedness in engaging in discussions around cost compared to their pre-intervention responses. The majority of participants (97.4%) reported that they would recommend the intervention to future students. A greater proportion of financially stressed students reported considering patient costs when making treatment decisions compared to their non-financially stressed peers. CONCLUSIONS: Targeted educational interventions to increase cost awareness have the potential to improve both medical student knowledge and preparedness to engage in cost-conscious care. Student financial stress may impact high-value care practices. Robust curricula on high-value care, including treatment-related financial hardship, should be formalized and universal within medical school training.

Disease characteristics and mortality among Asian women with breast cancer.

BACKGROUND: Asian women with breast cancer are often studied in aggregate, belying significant intragroup diversity. The authors sought to examine differences in breast cancer characteristics and outcomes among Asian women. METHODS: Asian, non-Hispanic Black, Hispanic, and non-Hispanic White women aged 18 years and older who were diagnosed with breast cancer from 1990 to 2016 were identified in the Surveillance, Epidemiology, and End Results 18 database. Asian patients were subclassified as Chinese, Japanese, Korean, Filipino, Vietnamese, South Asian (Asian Indian or Pakistani), Southeast Asian (SEA, i.e., Cambodian, Laotian, Hmong, or Thai), or other Asian. Unadjusted overall survival (OS) and cancer-specific survival (CSS) were estimated using the Kaplan-Meier method. Cox proportional hazards models were used to estimate adjusted OS and CSS. RESULTS: In total, 910,415 women were included (Asian, n = 63,405; Black, n = 92,226; Hispanic, n = 84,451; White, n = 670,333). Asian women had higher rates of human epidermal growth factor receptor 2 (HER2)-positive disease compared with White women (18.7% vs 13.8%) and had the highest 10-year unadjusted OS and CSS among all racial/ethnic groups (all P < .001). SEA women had the highest rates of stage IV disease at presentation, whereas Japanese women had the lowest rates (5.9% vs 2.7%; P < .001). Japanese women had the highest 10-year unadjusted CSS (89.4%; 95% confidence interval, 88.7%-90.1%) of any distinct Asian group, whereas SEA women had the worst unadjusted CSS (78%; 95% confidence interval, 74.1%-81.3%; P < .001). After adjustment, SEA women had the worst OS of any Asian group and were the only Asian group without improved OS compared with White women (reference category; P = .08). CONCLUSIONS: Breast cancer characteristics and outcomes vary significantly among Asian women. Future research should consider disaggregation by country or region of origin to identify subgroups that are at risk for worse outcomes than aggregated data may suggest. LAY SUMMARY: Asian women with breast cancer are frequently studied as a single entity. However, Asian ethnic groups differ greatly by country of origin, genetic ancestry, disease frequency, socioeconomic status, patterns of immigration, as well as dietary and cultural practices. Women of different Asian ethnicities vary significantly with regard to cancer characteristics, such as mortality and tumor subtype. Future research should disaggregate these populations to better understand, treat, and counsel Asian patients with breast cancer.

A Novel Staging System for De Novo Metastatic Breast Cancer Refines Prognostic Estimates.

OBJECTIVE: We aim to identify prognostic groups within a de novo metastatic cohort, incorporating both anatomic and biologic factors. BACKGROUND: Staging for breast cancer now includes anatomic and biologic factors, although the guidelines for stage IV disease do not account for how these factors may influence outcomes. METHODS: Adults with de novo metastatic breast cancer were selected from the National Cancer DataBase (2010-2013). Recursive partitioning analysis was used to group patients with similar overall survival (OS) based on clinical T/N stage, tumor grade, ER, PR, HER2, number of metastatic sites, and presence of bone-only metastases. Categories were created by amalgamating homogeneous groups based on 3-year OS rates (stage IVA: >50%, stage IVB: 30%-50%, stage IVC: <30%). RESULTS: 16,187 patients were identified; median follow-up was 32 months. 65.2% had 1 site of distant metastasis, and 42.9% had bone-only metastases. Recursive partitioning analysis identified the number of metastatic sites (1 vs >1) as the first stratification point, and ER status as the second stratification point for both resulting groups. Additional divisions were made based on HER2 status, PR status, cT stage, tumor grade, and presence of bone-only metastases. After bootstrapping, significant differences in 3-year OS were noted between the 3 groups [stage IVB vs IVA: HR 1.58 (95% confidence interval 1.50-1.67), stage IVC vs IVA: HR 3.54 (95% confidence interval 3.33-3.77)]. CONCLUSIONS: Both anatomic and biologic factors yielded reliable and reproducible prognostic estimates among patients with metastatic disease. These findings support formal stratification of de novo stage IV breast cancer into 3 distinct prognosis groups.

Dissatisfaction After Post-Mastectomy Breast Reconstruction: A Mixed-Methods Study.

BACKGROUND: Breast reconstruction is associated with improved patient well-being after mastectomy; however, factors that contribute to post-surgical dissatisfaction remain poorly characterized. METHODS: Adult women who underwent post-mastectomy implant-based or autologous breast reconstruction between 2015 and 2019 were recruited to participate in semi-structured interviews regarding their lived experiences with reconstructive care. Participants completed the BREAST-Q, and tabulated scores were used to dichotomize patient-reported outcomes as satisfied or dissatisfied (high or low) for each BREAST-Q domain. A convergent mixed-methods analysis was used to evaluate interviews for content related to satisfaction or dissatisfaction with breast reconstruction. RESULTS: Overall, we interviewed 21 women and identified 17 subcodes that corresponded with the five BREAST-Q domains. Sources of dissatisfaction were found to be related to the following domains: (a) low breast satisfaction due to asymmetry, cup size, and lack of sensation and physical feeling (n = 8, 38%); (b) poor sexual well-being due to shape, look and feel (n = 7, 78% [of 9 who discussed sexual well-being]); (c) reduced physical well-being of the chest due to persistent pain and weakness (n = 11, 52%); (d) reduced abdominal well-being due to changes in abdominal strength, numbness, and posture (n = 6, 38% [of 16 who underwent abdominally based reconstruction]); and (e) low psychosocial well-being impacted by an unexpected appearance that negatively influenced self-confidence and self-identity (n = 13, 62%). CONCLUSION: Patients may be unprepared for the physical, sexual, and psychosocial outcomes of breast reconstruction. Targeted strategies to improve preoperative education and shared decision making are needed to mitigate unexpectedness associated with breast reconstruction and related outcomes.

Incremental Spending Associated with Low-Value Treatments in Older Women with Breast Cancer.

BACKGROUND: In most women ≥ 70 years old with hormone-receptor-positive breast cancer, axillary staging and adjuvant radiotherapy provide no survival advantage over surgery and hormone therapy alone. Despite recommendations for their omission, sentinel lymph node biopsy (SLNB) and adjuvant radiotherapy rates remain high. While treatment side effects are well documented, less is known about the incremental spending associated with SLNB and adjuvant radiotherapy. METHODS: Using a statewide multipayer claims registry, we examined spending associated with breast cancer treatment in a retrospective cohort of women ≥ 70 years old undergoing surgery. RESULTS: 9074 women ≥70 years old underwent breast cancer resection between 2012 and 2019, with 78% (n = 7122) receiving SLNB and/or adjuvant radiotherapy within 90 days of surgery. Women undergoing SLNB were more likely to receive radiation (51% vs. 28%; p < 0.001 and OR = 2.68). Average 90-day spending varied substantially based upon treatment received, ranging from US$10,367 (breast-conserving surgery alone) to US$27,370 (mastectomy with SLNB and adjuvant radiotherapy). The relative increases in 90-day treatment spending in the breast-conserving surgery cohort was 65% for SLNB, 82% for adjuvant radiotherapy, and 120% for both treatments. CONCLUSIONS: SLNB and adjuvant radiotherapy have significant spending implications in older women with breast cancer, even though they are unlikely to improve survival.

Malignant phyllodes tumor and primary breast sarcoma; distinct rare tumors of the breast.

BACKGROUND: Malignant phyllodes (MP) and primary breast sarcomas (PBS) are rare neoplasms with overlapping histopathologic features. We compared overall survival (OS) and estimated the association of surgery and therapies with OS. METHODS: We utilized the National Cancer Database (2004-2016). Patients without surgery, unknown surgery, or margins, or Stage IV disease were excluded. Kaplan-Meier curves and Cox proportional hazards models were used to estimate unadjusted and adjusted OS, respectively. RESULTS: A total of 3209 (59.5%) MP, and 2185 (40.5%) PBS were identified. Despite a larger median tumor size in MP (46 vs. 40 mm PBS, p < 0.001), lumpectomy rate was higher for MP (52.9% vs. 27.0% PBS, p < 0.001). Compared to MP, PBS patients more frequently received radiation (28.9% vs. 24%), and chemotherapy (28.1% vs. 4%), both p < 0.001. Unadjusted OS was lower for PBS (57% vs. 85% MP, log-rank p < 0.001). PBS (vs. MP) had persistently worse survival (hazard ratio [HR]: 1.98, 95% confidence interval [CI]: 1.69-2.31) after adjustment. Receipt of adjuvant therapies was not associated with OS (either neoplasm); however, lumpectomy was associated with improved OS (vs. mastectomy) for both PBS (HR: 0.59, 95% CI: 0.50-0.75) and MP (HR: 0.65, 95% CI: 0.53-0.81). Positive margins had no association with OS for MP (HR: 1.09, 95% CI: 0.75-1.60), but was associated with worse survival for PBS (HR: 2.35, 95% CI: 1.82-3.02). DISCUSSION: We found significant survival differences between MP and PBS, with PBS having a consistently worse OS. Our findings support surgery as the mainstay of treatment for both tumor types and suggest that lumpectomy may be a reasonable option for select patients without compromising outcomes.

Characterizing participants in the North Carolina Breast and Cervical Cancer Control Program: A retrospective review of 90,000 women.

BACKGROUND: The North Carolina Breast and Cervical Cancer Control Program (NC BCCCP) provides breast cancer screening services to underserved women to mitigate disparities in access to care. The authors sought to characterize this understudied population. METHODS: Women 21 years old or older who underwent their first breast cancer screen through NC BCCCP from 2008 to 2018 were included. Demographic factors associated with the timeline of care and odds of a breast cancer diagnosis were identified with negative binomial and logistic regression, respectively. RESULTS: Of the 88,893 women identified, 45.5% were non-Hispanic (NH) White, 30.9% were NH Black, 19.6% were Hispanic, 1.7% were American Indian, and 1.1% were Asian. Breast cancer was diagnosed in 2.5% of the women (n = 2255). Hispanic women were the least likely to be diagnosed with breast cancer (odds ratio vs NH White women, 0.40; 95% confidence interval [CI], 0.34-0.47). Among patients with breast pathology, the median time to diagnosis was 19 days (interquartile range [IQR], 10-33 days), and the time to treatment was 33 days (IQR, 19-54 days). After adjustments, a longer time to diagnosis was significantly associated with age (incidence rate ratio [IRR], 1.01; 95% CI, 1.01-1.02) and being NH Black (vs NH White; IRR, 1.17; 95% CI, 1.06-1.29). A longer time to treatment was significantly associated with age (IRR, 1.01; 95% CI, 1.01-1.01), being NH Black (vs NH White; IRR, 1.20; 95% CI, 1.10-1.31), and being Hispanic (vs NH White; IRR, 1.22; 95% CI, 1.05-1.41). CONCLUSIONS: NC BCCCP participants with breast cancer received treatment within approximately 1 month of presentation, and this finding aligns with quality care benchmarks. Nevertheless, racial/ethnic disparities in timeliness of care persist, and this suggests opportunities for improvement. LAY SUMMARY: This review of approximately 90,000 participants in a breast cancer screening program for uninsured and underinsured women highlights the importance of safety net programs in providing timely care to underserved patients. The authors found that the North Carolina Breast and Cervical Cancer Control Program met timeliness benchmarks from the Centers for Disease Control and Prevention across all racial/ethnic groups. However, non-Hispanic Black women experienced relative delays in the time to diagnosis, and both non-Hispanic Black women and Hispanic women experienced relative delays in the time to treatment. These findings demonstrate how racial/ethnic disparities in the timeliness of care can persist even within a program intended to reduce barriers to access.

Time to surgery among women treated with neoadjuvant systemic therapy and upfront surgery for breast cancer.

PURPOSE: Time to surgery (TTS) is a potentially modifiable factor associated with survival after breast cancer diagnosis and can serve as a proxy for quality of oncologic care coordination. We sought to determine whether factors associated with delays in TTS vary between patients who receive neoadjuvant systemic therapy (NST) vs upfront surgery and whether the impact of these delays on overall survival (OS) varies with treatment sequence. METHODS: Women ≥ 18 years old with Stage I-III breast cancer were identified in the National Cancer Database (2004-2014). Multivariate linear regression stratified by treatment sequence (upfront surgery vs NST [neoadjuvant chemotherapy {NAC}, neoadjuvant endocrine therapy {NAE}, or both {NACE}]) was used to identify factors associated with TTS. Cox proportional hazards models were used to estimate the effect of TTS on overall survival (OS). RESULTS: Of 693,469 patients, 14.8% (n = 102,326) received NST (NAC n = 85,143, NAE n = 10,004, NACE n = 7179). Non-White race/ethnicity, no or government-issued insurance, more extensive surgery (i.e., mastectomy and contralateral prophylactic mastectomy vs breast-conserving surgery), and post-mastectomy reconstruction were associated with significantly longer adjusted TTS for NAC and upfront-surgery recipients, but only upfront-surgery patients had progressively worse OS with increasing TTS (> 180 vs ≤ 30 days: HR = 1.31, all p < 0.001). CONCLUSIONS: Surgery extent, race/ethnicity, and insurance were associated with TTS across treatment groups, but longer TTS was only associated with worse OS in upfront-surgery patients. Our findings can help inform surgeon-patient communication, shared decision making, care coordination, and patients' expectations throughout both NST and in the perioperative period.

Contralateral Axillary Nodal Metastases: Stage IV Disease or a Manifestation of Progressive Locally Advanced Breast Cancer?

BACKGROUND: Contralateral axillary nodal metastases (CAM) is classified as stage IV disease, although many centers treat CAM with curative intent. We hypothesized that patients with CAM, treated with multimodality therapy, would have improved overall survival (OS) versus patients with distant metastatic disease (M1) and similar OS to those with locally advanced breast cancer (LABC). METHODS: Using the NCDB (2004-2016), we categorized adult patients with node-positive breast cancer into three study groups: LABC, CAM, and M1. Kaplan-Meier curves were used to visualize the unadjusted OS. Cox proportional hazards models were used to estimate the association of study group with OS. RESULTS: A total of 94,487 patients were identified: 122 with CAM, 12,325 with LABC, and 82,040 with M1 (median follow-up 63.6 months). LABC and CAM patients had similar histology and rates of chemotherapy and endocrine therapy receipt. However, the CAM group had significantly larger tumors, more estrogen-receptor expression, higher T-stage, and more mastectomies than the LABC group. Compared with M1 patients, CAM patients were more likely to have grade 3 and cT4 tumors. Patients with CAM and LABC had similar 5-year unadjusted OS and significantly improved OS vs M1 patients. After adjustment, LABC and CAM patients continued to have similar OS and better OS vs M1 patients. CONCLUSIONS: CAM patients who receive multi-modal therapy with curative intent may have OS more comparable to LABC patients than M1 patients. Out data support a reevaluation of whether CAM should remain classified as M1, as N3 may better reflect disease prognosis and treatment goals.

Financial Toxicity Following Surgical Treatment for Breast Cancer: A Cross-sectional Pilot Study.

BACKGROUND: Despite growing national attention, there is limited understanding of the patient- and treatment-level characteristics related to treatment cost-associated distress ("financial toxicity") in breast cancer patients. Our aim is to identify risk factors for financial toxicity amongst breast cancer patients undergoing surgical treatment. METHODS: This is a single-institution cross-sectional survey of adult female breast cancer patients who underwent lumpectomy or mastectomy between January 2018 and June 2019. Financial toxicity was measured via the 11-item comprehensive score for financial toxicity (COST) instrument. Responses were linked with data on patient demographics and clinical history abstracted from the corresponding medical record. Multivariate regression was used to identify patient- and treatment-level factors associated with worsening financial toxicity. Secondary outcome measures included self-reported coping strategies for high treatment costs. RESULTS: A total of 571 patients were included; overall, these individuals were mostly white (76.0%), in-state residents (72.3%), and married (73.0%). Following multivariate analysis, lower financial distress was associated with the use of supplemental insurance, increasing annual household income, and a higher credit score (score > 740). Conversely, work reduction or cessation, increased out-of-pocket spending, advanced tumor stage, and being employed at the time of diagnosis were associated with increased financial distress. Patients with higher reported financial distress were more likely to decrease their spending on food, clothing, and leisure activities. CONCLUSIONS: Financial toxicity was associated with baseline demographic, disease, and treatment characteristics in our cohort of insured patients. These characteristics may be critical opportunities for interventions related to financial navigation along the treatment continuum.

Treatment Patterns and Outcomes of Women with Breast Cancer and Supraclavicular Nodal Metastases.

BACKGROUND: In 2002, breast cancer patients with supraclavicular nodal metastases (cN3c) were downstaged from AJCC stage IV to IIIc, prompting management with locoregional treatment. We sought to estimate the impact of multimodal therapy on overall survival (OS) in a contemporary cohort of cN3c patients. METHODS: Women ≥ 18 years with cT1-T4c/cN3c invasive breast cancer who underwent systemic therapy were identified from the 2004-2016 National Cancer Database. We compared three patient cohorts: (a) cN3c + multimodal therapy (systemic therapy, surgery, and radiation); (b) cN3c + non-standard therapy; and, (c) cM1. Logistic regression identified factors associated with receipt of multimodal therapy and Kaplan-Meier was used to estimate unadjusted OS. The Cox proportional hazards model estimated effects of diagnosis and treatment on OS after adjustment. RESULTS: Overall, 1827 (3.7%) patients with cN3c disease and 46,919 (96.3%) cM1 patients were identified. Of cN3c patients, 74.5% (n = 1362) received multimodal therapy and 25.5% (n = 465) received non-standard therapy; receipt of multimodal therapy was associated with improved 5-year OS (multimodal: 59% vs. M1: 28% vs. non-standard: 28%, log-rank p < 0.001). Adjusting for covariates, non-standard therapy was associated with an increased risk of death compared with receipt of multimodal therapy (HR 2.20, 95% CI 1.71-2.83, p < 0.001). Private insurance was the only patient characteristic associated with a greater likelihood of receiving multimodal therapy (OR 2.81; 95% CI, 1.64-4.82; p < 0.001). CONCLUSION: Women with cN3c breast cancer who received multimodal therapy demonstrated improved overall survival when compared with patients undergoing non-standard therapy and those with metastatic (M1) disease. Although selection bias may contribute to worse overall survival among cN3c patients undergoing non-standard therapy, national guidelines should encourage locoregional treatment in carefully selected patients.

Navigating the high costs of cancer care: opportunities for patient engagement.

Over the past decade, the financial burden of cancer care on patients and their families has garnered increased attention. Many of the potential solutions have focused on system-level interventions such as adopting value-based payment models and negotiating drug prices; less consideration has been given to actions at the patient level to address cancer care costs. We argue that it is imperative to develop and support patient-level strategies that engage patients and consider their preferences, values and individual circumstances. Opportunities to meet these aims and improve the economic experience of patients in oncology are discussed, including: shared decision-making and communication, financial navigation and treatment planning, digital technology and alternative care pathways, and value-based insurance design.

Lay abstract The financial burden of cancer care on patients and their families is a growing problem and action is critically needed to alleviate the high costs of such care. So far, potential solutions have focused on system-level interventions, with less consideration given to solutions at the patient level. This review argues that it is imperative to develop and support patient-level strategies that engage patients. Next, the review presents evidence of the interplay between patient preferences and values and the costs of cancer care. Finally, opportunities to enhance engagement and improve the economic experience of patients in oncology are discussed, including: shared decision-making and communication, financial navigation and treatment planning, digital technology and alternative care pathways, and value-based insurance design.

Implications for Breast Cancer Restaging Based on the 8th Edition AJCC Staging Manual.

OBJECTIVE: We assessed the changes that have resulted from the latest breast cancer staging guidelines and the potential impact on prognosis. BACKGROUND: Contemporary data suggest that combining anatomic staging and tumor biology yields a predictive synergy for determining breast cancer prognosis. This forms the basis for the American Joint Committee on Cancer's (AJCC) Staging Manual, 8th edition. We assessed the changes that have resulted from the new staging guidelines and the potential impact on prognosis. METHODS: Women with stages I to III breast cancer from 2010 to 2014 in the National Cancer Data Base were pathologically staged according to the 7th and 8th editions of the AJCC Staging Manual. Patient characteristics and restaging outcomes were summarized. Unadjusted overall survival (OS) was estimated, and differences were assessed. Cox proportional-hazards models were utilized to estimate the adjusted association of stage with OS. RESULTS: After restaging the 493,854 women identified, 6.8% were upstaged and 29.7% were downstaged. The stage changes varied by tumor histology, receptor status, tumor grade, and Oncotype DX scores (all P < 0.0001). Applying the 8th edition criteria yielded an incremental reduction in survival for each increase in stage, which was not consistently seen in the 7th edition. In a subgroup analysis based on hormone receptor (HR) status, those with stages II and III, and HR- disease had a worse OS than those with HR+ disease. CONCLUSIONS: Applying the 8th edition staging criteria resulted in a stage change for >35% of patients diagnosed with invasive breast cancer and refined OS estimates. Overall, the transition to the 8th edition is expected to better drive clinical care, treatment recommendations, and future research.

Axillary lymph node dissection in node-positive breast cancer: are ten nodes adequate and when is enough, enough?

PURPOSE: National guidelines define adequate axillary lymph node dissections as those yielding ≥ 10 lymph nodes (LNs). We aimed to identify the optimal LN yield among node-positive patients. METHODS: Using the National Cancer Data Base (2010-2015), we categorized node-positive patients as follows: (1) neoadjuvant chemotherapy (NAC, cN1-3 or ypN1mi-3) or (2) upfront surgery (pN1-3). A restricted cubic splines model was used to estimate LN retrieval thresholds associated with change in overall survival (OS). RESULTS: 129,685 patients were identified: 21.2% NAC, 78.8% upfront surgery. Low, moderate, and high retrieval thresholds were estimated to be 1-6, 7-21, and > 21 LNs (upfront surgery), and 1-7, 8-22, and > 22 LNs (NAC). In an adjusted model, high versus low LN yield was associated with greater receipt of adjuvant chemotherapy (upfront surgery OR 1.96, p < 0.001) and greater use of adjuvant radiation (upfront surgery OR 1.08, p = 0.02; NAC OR 1.23, p = 0.002). After adjustment, high versus low LN retrieval was associated with improved OS (upfront surgery HR 0.86, p < 0.001; NAC HR 0.77, p < 0.001). Worse OS was associated with retrieving fewer LNs, likely as a result of an under-staged axilla and missed opportunity for adjuvant therapy, while better OS was independently associated with retrieval of up to approximately 20 LNs, after which survival did not improve. CONCLUSION: In node-positive breast cancer, the number of nodes retrieved is significantly associated with an increased positive nodal count and greater use of adjuvant therapy. Removal of approximately 20 LNs may improve survival by both more accurate nodal staging and increased adjuvant therapy use.
