Patient-reported symptom severity, interference with daily activities, and adverse events in older and younger women receiving chemotherapy for early breast cancer.

BACKGROUND: To the authors' knowledge, it is unknown whether patient-reported symptom severity and symptom interference with daily activities differ between younger (aged <65 years) and older (aged ≥65 years) women receiving similar chemotherapy regimens for early breast cancer (EBC). METHODS: Study participants rated 17 side effects of chemotherapy regimens currently in use in clinical practice (2014-2019). RESULTS: Of 284 women with EBC (stage I-III), approximately 57% were aged <65 years and 43% were aged ≥65 years. For anthracycline-based regimens, a higher percentage of younger women reported moderate, severe, or very severe (MSVS) hot flashes (49% vs 18%) (P < .001). For nonanthracycline regimens, a higher percentage of younger women reported MSVS hot flashes (38% vs 19%) (P = .009) and a lower percentage reported MSVS arthralgia (28% vs 49%) (P = .005). With regard to symptom interference with daily activities, a higher percentage of younger women being treated with anthracycline-based regimens reported MSVS hot flashes (32% vs 7%) (P = .001) and myalgia (38% vs 18%) (P = .02). For nonanthracycline chemotherapy, a higher percentage of younger women reported MSVS interference for hot flashes (26% vs 9%) (P = .006) and lower percentages reported abdominal pain (13% vs 28%) (P = .02). Overall, there were no significant differences noted among younger versus older patients with regard to hospitalizations (19% vs 12%; P = .19), dose reductions (34% vs 31%; P = .50), dose delays (22% vs 25%; P = .59), or early treatment discontinuation (16% vs 16%; P = .9546). CONCLUSIONS: Older and younger women with EBC who were treated with identical chemotherapy regimens generally experienced similar levels of symptom severity, symptom-related interference with daily activities, and adverse events. LAY SUMMARY: In this study, women receiving chemotherapy for early breast cancer rated the severity of 17 symptoms and symptom interference with their activities of daily living. Older (aged ≥65 years) and younger (aged <65 years) women who received identical chemotherapy regimens generally experienced similar levels of symptom severity, symptom-related interference with daily activities, and adverse events.

Older adult participation in cancer clinical trials: A systematic review of barriers and interventions.

Cancer is a disease of aging and, as the world's population ages, the number of older persons with cancer is increasing and will make up a growing share of the oncology population in virtually every country. Despite this, older patients remain vastly underrepresented in research that sets the standards for cancer treatments. Consequently, most of what we know about cancer therapeutics is based on clinical trials conducted in younger, healthier patients, and effective strategies to improve clinical trial participation of older adults with cancer remain sparse. For this systematic review, the authors evaluated published studies regarding barriers to participation and interventions to improve participation of older adults in cancer trials. The quality of the available evidence was low and, despite a literature describing multifaceted barriers, only one intervention study aimed to increase enrollment of older adults in trials. The findings starkly amplify the paucity of evidence-based, effective strategies to improve participation of this underrepresented population in cancer trials. Within these limitations, the authors provide their opinion on how the current cancer research infrastructure must be modified to accommodate the needs of older patients. Several underused solutions are offered to expand clinical trials to include older adults with cancer. However, as currently constructed, these recommendations alone will not solve the evidence gap in geriatric oncology, and efforts are needed to meet older and frail adults where they are by expanding clinical trials designed specifically for this population and leveraging real-world data.

Effects of Breast Cancer Adjuvant Chemotherapy Regimens on Expression of the Aging Biomarker, p16INK4a.

Background: Although chemotherapy saves lives, increasing evidence shows that chemotherapy accelerates aging. We previously demonstrated that mRNA expression of p16INK4a , a biomarker of senescence and molecular aging, increased early and dramatically after beginning adjuvant anthracycline-based regimens in early stage breast cancer patients. Here, we determined if changes in p16INK4a expression vary by chemotherapy regimen among early stage breast cancer patients. Methods: We conducted a study of stage I-III breast cancer patients receiving adjuvant or neoadjuvant chemotherapy. p16INK4a expression was analyzed prechemotherapy and postchemotherapy (median 6.2 months after the last chemotherapy) in peripheral blood T lymphocytes. Chemotherapy-induced change in p16INK4a expression was compared among regimens. All statistical tests were 2-sided. Results: In 146 women, chemotherapy was associated with a statistically significant increase in p16INK4a expression (accelerated aging of 17 years; P < .001). Anthracycline-based regimens were associated with the largest increases (accelerated aging of 23 to 26 years; P ≤ .008). Nonanthracycline-based regimens demonstrated a much smaller increase (accelerated aging of 9 to 11 years; P ≤ .15). In addition to the type of chemotherapy regimen, baseline p16INK4a levels, but not chronologic age or race, were also associated with the magnitude of increases in p16INK4a . Patients with lower p16INK4a levels at baseline were more likely to experience larger increases. Conclusions: Our findings suggest that the aging effects of chemotherapy may be influenced by both chemotherapy type and the patient's baseline p16INK4a level. Measurement of p16INK4a expression is not currently available in the clinic, but nonanthracycline regimens offering similar efficacy as anthracycline regimens might be favored.

Factors associated with falls in older women with breast cancer: the use of a brief geriatric screening tool in clinic.

PURPOSE: Unintentional falls and breast cancer are common among older women, but the associations between them are understudied. We aimed to identify factors associated with falls in older women with breast cancer. METHODS: We retrospectively reviewed clinical records of older women with breast cancer at Duke Medical Center who had completed the Senior Adult Oncology Program geriatric assessment. Characteristics were compared between women had had at least one fall in the past year and those who did not. Pearson's Chi-square tests and t tests were used for comparison of groups' characteristics. Logistic regression determined factors associated with falling. RESULTS: We identified 425 women, age 76.2 years (range 65-89 years), at the time of the assessment. 118 (27.8%) women reported a fall in the prior year. Age, race, ethnicity, and time since diagnosis (all p > 0.05) were similar between groups. In univariate analyses, metastatic disease (p = 0.023) and history of endocrine therapy (p = 0.042) were more common among women who fell. Women who fell had lower systolic (p = 0.001), diastolic (p < 0.001) blood pressures, and SpO2 (p = 0.018). Women who had fallen had a higher Charlson Comorbidity Index (CCI: p = 0.033), and were more likely to report using a walking aide (p < 0.001), nutritional issues (p = 0.006), and depression symptoms (p = 0.038). In multivariate analysis, falling was associated with low DBP (OR 0.93; p = 0.0017), low SpO2 (OR 0.79; p = 0.0169), a higher CCI (OR 1.23; p = 0.0076), and depression symptoms (OR 1.61; p = 0.039). CONCLUSIONS: Among older women with breast cancer, depressive symptoms, higher comorbidity level, and vital sign measurements were associated with having fallen.
