For patients with breast cancer, delays in chemotherapy initiation have been adversely associated with recurrence and survival. We evaluated patient‐level factors associated with delayed chemotherapy initiation, from both diagnosis and surgery, in a community‐based cohort of women with early‐stage breast cancer. For the Optimal Breast Cancer Chemotherapy Dosing study, we identified a cohort of 34,109 women diagnosed with stage I–IIIA breast cancer at two U.S. integrated healthcare delivery systems between 2004 and 2019. We used logistic regression to calculate odds ratios (OR) and 95% confidence intervals (CI) to identify patient factors associated with delays in chemotherapy initiation after diagnosis (≥90 days) and surgery (≥60 days). Among 10,968 women receiving adjuvant chemotherapy, 21.1% experienced delays in chemotherapy initiation after diagnosis and 21.3% after surgery. Older age, non‐Hispanic Black and Hispanic race and ethnicity, and ER+ and/or PR+ disease were associated with increased likelihood of delays to chemotherapy initiation after diagnosis and surgery. People diagnosed in 2012–2019 (vs. 2005–2011), with a higher grade and larger tumor size were less likely to experience delays. Other factors were associated with a higher likelihood of delays specifically from diagnosis (earlier stage, mastectomy vs. breast‐conserving surgery), or surgery (higher comorbidity, increased nodal number). Women diagnosed with breast cancer who were at highest risk of progression and recurrence were less likely to experience delays in chemotherapy initiation after diagnosis and surgery. Understanding reasons for chemotherapy delays beyond patient factors may be potentially important to reduce risk of breast cancer recurrence and progression. [ABSTRACT FROM AUTHOR]

Background: Guidelines informing chemotherapy regimen selection are based on clinical trials with participants who do not necessarily represent general populations with breast cancer. Understanding who receives nonguideline regimens is important for understanding real-world chemotherapy administration and how it relates to patient outcomes. Methods: Using data from the Optimal Breast Cancer Chemotherapy Dosing (OBCD) study, based at Kaiser Permanente Northern California (2006-2019) and Kaiser Permanente Washington (2004-2015), we use logistic regression to examine the associations between patient characteristics and receipt of nonguideline chemotherapy regimens among 11,293 women with primary stage I to IIIA breast cancer receiving chemotherapy. Results: The use of nonguideline regimens was strongly associated with several factors, including older age [=80 vs. 18-39 years: OR, 5.25; 95% confidence interval (CI), 3.06-9.00; P-trend = 0.002] and HER2 status (HER2+ vs. HER2-: OR, 3.44; 95% CI, 3.06-3.87) and was less likely in women with larger tumor size (>5 cm vs. 0.1 to =0.5 cm: OR, 0.56; 95% CI, 0.36-0.87; P-trend = 0.01) and diagnosed in later years (2012-2019 vs. 2005-2011: OR, 0.80; 95% CI, 0.71-0.90). Factors associated varied by type of nonguideline regimens. For example, women with comorbidity and older age were more likely to receive nonguideline drug combinations in particular, whereas women with larger tumor size were less likely to receive nonguideline administration schedules. Conclusions: Nonguideline chemotherapy regimens are more likely in certain patient populations. [ABSTRACT FROM AUTHOR]

Aims The most appropriate timing of exercise therapy to improve cardiorespiratory fitness (CRF) among patients initiating chemotherapy is not known. The effects of exercise therapy administered during, following, or during and following chemotherapy were examined in patients with breast cancer. Methods and results Using a parallel-group randomized trial design, 158 inactive women with breast cancer initiating (neo)adjuvant chemotherapy were allocated to receive (1:1 ratio): usual care or one of three exercise regimens—concurrent (during chemotherapy only), sequential (after chemotherapy only), or concurrent and sequential (continuous) (n = 39/40 per group). Exercise consisted of treadmill walking three sessions/week, 20–50 min at 55%–100% of peak oxygen consumption (VO2peak) for ≈16 (concurrent, sequential) or ≈32 (continuous) consecutive weeks. VO2peak was evaluated at baseline (pre-treatment), immediately post-chemotherapy, and ≈16 weeks after chemotherapy. In intention-to-treat analysis, there was no difference in the primary endpoint of VO2peak change between concurrent exercise and usual care during chemotherapy vs. VO2peak change between sequential exercise and usual care after chemotherapy [overall difference, −0.88 mL O2·kg−1·min−1; 95% confidence interval (CI): −3.36, 1.59, P = 0.48]. In secondary analysis, continuous exercise, approximately equal to twice the length of the other regimens, was well-tolerated and the only strategy associated with significant improvements in VO2peak from baseline to post-intervention (1.74 mL O2·kg−1·min−1, P < 0.001). Conclusion There was no statistical difference in CRF improvement between concurrent vs. sequential exercise therapy relative to usual care in women with primary breast cancer. The promising tolerability and CRF benefit of ≈32 weeks of continuous exercise therapy warrant further evaluation in larger trials. [ABSTRACT FROM AUTHOR]

Background: In clinical trials and clinical practice, patient-reported outcomes are almost always assessed using multiple patient-reported outcome measures at the same time. This raises concerns about whether patient responses are affected by the order in which the patient-reported outcome measures are administered. Methods: This questionnaire-based study of order effects included adult cancer patients from five cancer centers. Patients were randomly assigned to complete questionnaires via paper booklets, interactive voice response system, or tablet web survey. Linear Analogue Self-Assessment, Patient-Reported Outcomes Version of the Common Terminology Criteria for Adverse Events, and Patient-Reported Outcomes Measurement Information System assessment tools were each used to measure general health, physical function, social function, emotional distress/anxiety, emotional distress/depression, fatigue, sleep, and pain. The order in which the three tools, and domains within tools, were presented to patients was randomized. Rates of missing data, scale scores, and Cronbach's alpha coefficients were compared by the order in which they were assessed. Analyses included Cochran–Armitage trend tests and mixed models adjusted for performance score, age, sex, cancer type, and curative intent. Results: A total of 1830 patients provided baseline patient-reported outcome assessments. There were no significant trends in rates of missing values by whether a scale was assessed earlier or later. The largest order effect for scale scores was due to a large mean score at one assessment time point. The largest difference in Cronbach's alpha between the versions for the Patient-Reported Outcomes Measurement Information System scales was 0.106. Conclusion: The well-being of a cancer patient has many different aspects such as pain, fatigue, depression, and anxiety. These are assessed using a variety of surveys often collected at the same time. This study shows that the order in which the different aspects are collected from the patient is not important.

Burkitt lymphoma (BL) is a highly aggressive B-cell malignancy that occurs with increased frequency among patients infected with HIV. Until recently, the immunocompromised state of patients with HIV and BL was generally deemed to preclude the use of the intensive chemotherapeutic regimens used to treat HIV-negative patients due to toxicity issues. However, the advent of highly active antiretroviral therapy (HAART) and the mounting evidence that less intensive lymphoma regimens are ineffective in BL have led investigators to treat HIV-positive patients with the same chemotherapy now established as the standard of care for immunocompetent patients. Data suggest that these current approaches, along with supportive care, may result in improved patient outcomes. In contrast, the role of adjunctive immunotherapy with rituximab in HIV-BL remains undefined. Further studies, including randomized clinical trials, are needed to better delineate the optimal treatment for patients with this devastating disease.

Many cancer patients experience a reduction in work status during cancer treatment. Authors analyzed cross-sectional survey data from U.S. cancer patients and survivors to examine the relationship between reduced work status and cost-related nonadherence , defined as skipping or forgoing medical treatments or medications due to cost. Of 381 respondents who were working at the time of diagnosis, 143 reported a reduction in work status during treatment. Age, racial identity, level of education, and treatment type were associated with reductions in work status. Respondents who reduced work status had higher odds of engaging in cost-related nonadherence than those with stable employment. Authors conclude that reduced work status is associated with nonadherence that can undermine treatment benefit and lead to disease progression. This association is troubling given that African American respondents were more likely to report reduced work status during treatment, potentially exacerbating existing cancer health disparities. To reduce treatment nonadherence, social workers should assess for potential employment problems and be prepared to intervene through counseling, community resource referrals, and direct financial assistance. Social workers should be aware of how structural racism is reproduced through inequitable labor policies and practices that have direct implications for health and access to care.

BACKGROUND: The coronavirus pandemic has highlighted the health and financial vulnerabilities of essential workers, especially among women. OBJECTIVE: The purpose of this study is to understand the workplace environment of essential workers. METHODS: We used data from a prospective cohort study of disparities in employment outcomes among women undergoing breast cancer treatment between 2010–2018 in New York City. We characterized participants as essential or non-essential based on self-reported occupation/industry and New York State executive orders issued during the pandemic. We compared job benefits and perceptions of workplace environment between groups. RESULTS: There were 563 participants: 341 essential and 222 non-essential workers. Essential workers less frequently reported access to disability pay through work [n(%): 148 (58) versus 130 (73), p < 0.01]. Essential workers in unions had greater availability of sick leave and disability pay than non-unionized essential workers (86% versus 53%, p < 0.01, and 76% versus 46%, p < 0.01, respectively). Health insurance differed by essential worker status (p < 0.01): essential workers more frequently had public insurance (29% versus 18%). Surprisingly, in multivariable analyses controlling for age, race/ethnicity, income, education, chemotherapy receipt, and comfort with English, essential workers were less likely to say their employer had treated them unfairly (p < 0.01). However, minorities were less likely to say their employer was accommodating (p = 0.03) and more likely to say their employer had treated them unfairly (p < 0.01) than Non-Latina Whites. CONCLUSIONS: We identified vulnerabilities in workplace protections, particularly among essential workers not in unions. Minority women more often had negative perceptions of their work environment, possibly reflecting employer bias. [ABSTRACT FROM AUTHOR]

This report describes the rationale, purpose and design of A011801 (CompassHER2 RD), an ongoing prospective, multicenter, Phase III randomized trial. Eligible patients in the United States (US) and Canada with high-risk (defined as ER-negative and/or node-positive) HER2-positive (HER2+) residual disease (RD) after a predefined course of neoadjuvant chemotherapy and HER2-directed treatment are randomized 1:1 to adjuvant T-DM1 and placebo, versus T-DM1 and tucatinib. Patients have also received adjuvant radiotherapy and/or endocrine therapy, if indicated per standard of care guidelines. The primary objective of the trial is to determine if the invasive disease-free survival (iDFS) with T-DM1 plus tucatinib is superior to iDFS with T-DM1 plus placebo; other outcomes of interest include overall survival (OS), breast cancer-free survival (BCFS), distant recurrence-free survival (DRFS), brain metastases-free survival (BMFS) and disease-free survival (DFS). Correlative biomarker, quality of life (QoL) and pharmacokinetic (PK) end points are also evaluated. [ABSTRACT FROM AUTHOR]

Background More than one-half of breast cancer cases are diagnosed among women aged younger than 62 years, which may result in employment challenges. This study examined whether cancer-related employment disruption was associated with increased financial hardship in a national US study of women with breast cancer. Methods Women with breast cancer who were enrolled in the Sister or Two Sister Studies completed a survivorship survey in 2012. Employment disruption was defined as stopping work completely or working fewer hours after diagnosis. Financial hardship was defined as: 1) experiencing financial problems paying for cancer care, 2) borrowing money or incurring debt, or 3) filing for bankruptcy because of cancer. Prevalence ratios and 95% confidence intervals for the association between employment disruption and financial hardship were estimated using multivariable Poisson regression with robust variance. Results We analyzed data from women employed at diagnosis (n = 1628). Women were a median age of 48 years at diagnosis and 5.6 years from diagnosis at survey completion. Overall, 27.3% of women reported employment disruption (15.4% stopped working; 11.9% reduced hours), and 21.0% experienced financial hardship (16.0% had difficulty paying for care; 12.6% borrowed money or incurred debt; 1.8% filed for bankruptcy). In adjusted analysis, employment disruption was associated with nearly twice the prevalence of financial hardship (prevalence ratio = 1.93, 95% confidence interval = 1.58 to 2.35). Conclusions Women experiencing employment disruptions after breast cancer may be more vulnerable to financial hardship. Findings highlight the need to target risk factors for employment disruption, facilitate return to work or ongoing employment, and mitigate financial consequences after cancer.

Purpose: Food insecurity, which leads to adverse health outcomes, has even more severe implications for cancer patients. Yet medically underserved cancer patients are more likely to be food insecure than the general population. Methods: This study is a cross-sectional analysis of intake data from patients who participated in the Integrated Cancer Care Access Network (ICCAN). ICCAN is a specialized program that addresses socioeconomic barriers to cancer care among underserved cancer patients in NYC. This study utilized ICCAN data from 2011 to 2017. The USDA food insecurity score, self-reported SNAP receipt, and SNAP eligibility based on household income were compared between SNAP and non-SNAP recipients. Results: 681 patients were assessed for food insecurity. Sixty-nine percent of participants lived in food insecure households. Despite SNAP assistance, most SNAP recipients (68%) were food insecure; 69% of respondents who did not receive SNAP were also food insecure. Conclusions: Underserved cancer patients who receive SNAP are still food insecure, hence at more significant risk for its associated negative outcomes. Supplemental programs for patients with chronic diseases are needed in clinics with large low income populations. SNAP benefits should account for the additional financial burden posed by treatment costs and exceptional circumstances faced by cancer patients. [ABSTRACT FROM AUTHOR]

Background Chemotherapy-induced peripheral neuropathy (CIPN) is a common, debilitating side effect that worsens quality of life and increases the risk of falls in cancer survivors. Evidence of yoga's safety and efficacy in treating CIPN is lacking. Methods In a randomized controlled study, we assigned breast and gynecological cancer survivors with persistent moderate-to-severe CIPN pain, numbness, or tingling with a score of 4 or greater (0-10 numeric rating scale [NRS]) for at least 3 months after chemotherapy to 8 weeks of usual care or yoga focused on breathwork and musculoskeletal conditioning. Primary endpoint was treatment arm differences for NRS, and secondary endpoints were Functional Assessment of Cancer Therapy/Gynecologic Oncology Group-Neurotoxicity subscale (FACT/GOG-Ntx), and Functional Reach Test after week 8. We tested treatment arm differences for each outcome measure using linear mixed models with treatment-by-time interactions. All statistical tests were two-sided. Results We randomly assigned 41 participants into yoga (n = 21) or usual care (n = 20). At week 8, mean NRS pain decreased by 1.95 points (95% confidence interval [CI] = -3.20 to -0.70) in yoga vs 0.65 (95% CI = -1.81 to 0.51) in usual care (P =.14). FACT/GOG-Ntx improved by 4.25 (95% CI = 2.29 to 6.20) in yoga vs 1.36 (95% CI = -0.47 to 3.19) in usual care (P =.035). Functional reach, an objective functional measure predicting the risk of falls, improved by 7.14 cm (95% CI = 3.68 to 10.59) in yoga and decreased by 1.65 cm (95% CI = -5.00 to 1.72) in usual care (P =.001). Four grade 1 adverse events were observed in the yoga arm. Conclusion Among breast and gynecological cancer survivors with moderate-to-severe CIPN, yoga was safe and showed promising efficacy in improving CIPN symptoms. [ABSTRACT FROM AUTHOR]
