Investigating associations between health-related quality of life and endocrine therapy underuse in women with early-stage breast cancer

Purpose Endocrine therapy (ET) underuse puts women at increased risk for breast cancer (BC) recurrence. Our objective was to determine if health-related quality of life (HRQOL) subgroups were associated with underuse. Methods Data came from the third phase of the Carolina Breast Cancer Study. We included 1,599 women with hormone receptor-positiveBCage 20 to 74 years.HRQOLwas measured, on average,5months postdiagnosis. Subgroups were derived using latent profile (LP) analysis. Underuse was defined as not initiating or adhering to ET by 36 months postdiagnosis. Multivariable logistic regression models estimated adjusted odds ratios (ORs) between HRQOL LPs and underuse. The best HRQOL LP was the reference. Chemotherapy- and race-stratified models were estimated, separately. Results Initiation analyses included 953womenwhohad not begun ET by their 5-month survey. Of these, 154 never initiated ET. Adherence analyses included 1,114 ET initiators, of whom 211 were nonadherent.HRQOLwas not significantly associated with noninitiation, except among nonchemotherapy users, with membership in the poorest LP associated with increased odds of noninitiation (adjusted OR, 5.5; 95% CI, 1.7 to 17.4). Membership in the poorest LPs was associated with nonadherence (LP1: adjusted OR, 2.2; 95% CI, 1.2 to 4.0 and LP2: adjusted OR,1.9;95%CI, 1.1 to 3.6). Membershipin the poorestLPwasassociated with nonadherence among nonchemotherapy users (adjusted OR, 2.1; 95% CI, 1.2 to 5.1). Conclusion Ourresults suggestwomenwith poorHRQOLduring active treatmentmaybe at increased risk for ET underuse. Focusing on HRQOL, a modifiable factor, may improve targeting of future interventions early in theBCcontinuum to improve ET initiation and adherence and prevent BC recurrence

Computer‐aided photo‐identification of a rare stingray, Megatrygon microps

We have defined protocol for photo‐identification to identify individual Megatrygon microps. 104 identification photographs were taken between 2005 and 2019. Spot patterns on the dorsal surface were used to identify individuals. Unique scarring on 8 re‐observed M. microps provided an independent confirmation of pattern stability of up to 761 days. Previously, studies have lacked statistical testing to validate photo‐identification approach. The I3S photo‐matching software was proven to successfully match images, identifying 69 individuals. A photo‐matching software facilitates an open‐source platform for identifying individual M. microps, allowing for better population assessments

Examining health-related quality of life patterns in women with breast cancer

Purpose: We aimed to identify subgroups of women with breast cancer who experience different health-related quality of life (HRQOL) patterns during active treatment and survivorship and determine characteristics associated with subgroup membership. Methods: We used data from the third phase of the population-based Carolina Breast Cancer Study and included 2142 women diagnosed with breast cancer from 2008 to 2013. HRQOL was measured, on average, 5 and 25 months post diagnosis. Latent profile analysis was used to identify HRQOL latent profiles (LPs) at each time point. Latent transition analysis was used to determine probabilities of women transitioning profiles from 5 to 25 months. Multinomial logit models estimated adjusted odds ratios (aORs) and 95% confidence intervals for associations between patient characteristics and LP membership at each time point. Results: We identified four HRQOL LPs at 5 and 25 months. LP1 had the poorest HRQOL and LP4 the best. Membership in the poorest profile at 5 months was associated with younger age aOR 0.95; 0.93–0.96, White race aOR 1.48; 1.25–1.65, being unmarried aOR 1.50; 1.28–1.65 and having public aOR 3.09; 1.96–4.83 or no insurance aOR 6.51; 2.12–20.10. At 25 months, Black race aOR 1.75; 1.18–1.82 was associated with the poorest profile membership. Black race and smoking were predictors of deteriorating to a worse profile from 5 to 25 months. Conclusions: Our results suggest patient-level characteristics including age at diagnosis and race may identify women at risk for experiencing poor HRQOL patterns. If women are identified and offered targeted HRQOL support, we may see improvements in long-term HRQOL and better breast cancer outcomes

Placental CD4(+) T cells from preeclamptic patients cause autoantibodies to the angiotensin II type I receptor and hypertension in a pregnant rat model of preeclampsia

AIM: Preeclampsia (PE) is a hypertensive disorder of pregnancy associated with activated CD4(+) T cells and autoantibodies to angiotensin II type 1 receptor (AT1-AA). We have previously shown that CD4(+) T cells isolated from women with PE cause hypertension, increased tumor necrosis factor alpha (TNF-α), endothelin-1, and soluble fms-like tyrosine kinase-1 (sFlt-1) when injected into pregnant nude-athymic rats compared to CD4(+) T cells from normal pregnant (NP) women. However, the role of PE CD4(+) T cells to cause AT1-AA as a mechanism of hypertension is not known. Our goal was to determine if PE CD4(+) T cells stimulate AT1-AA in pregnant nude-athymic rats. METHODS: CD4(+) T cells were isolated from human NP and PE placentasand injected into nude-athymic rats on gestational day (GD) 12. In order to examine the role of the PE CD4(+) T cells to stimulate B cell secretion of AT1-AA, a subset of the rats receiving PE CD4(+) T cells were treated with rituximab on GD 14 or anti-CD40 ligand (anti-CD40L) on GD 12. On GD 19, mean arterial pressure (MAP) and tissues were obtained. RESULTS: MAP [114 ± 1 mmHg (n = 9)] and AT1-AA [19.8 ± 0.9 beats per minute (bpm, n = 4)] were increased in NP nude + PE CD4(+) T cells compared to NP nude + NP CD4(+) T cells [98 ± 2 mmHg (n = 7, P < 0.05) and 1.3 ± 0.9 bpm (n = 5, P < 0.05)]. Rituximab (103 ± 2 mmHg, n = 3, P < 0.05) and anti-CD40L (102 ± 1 mmHg, n = 3, P < 0.05) lowered MAP compared to NP nude + PE CD4(+) T cells. Circulating a proliferation-inducing ligand (APRIL) and placental angiotensin-converting enzyme 2 (ACE-2) activity was increased in response to PE CD4(+) T cells. CONCLUSIONS: These results show that placental CD4(+) T cells play an important role in the pathophysiology of PE, by activating B cells secreting AT1-AA to cause hypertension during pregnancy

Congruence of patient- and clinician-reported toxicity in women receiving chemotherapy for early breast cancer

Background: The National Cancer Institute's Patient-Reported Outcomes Version of the Common Terminology Criteria for Adverse Events, collected alongside the clinician-reported Common Terminology Criteria for Adverse Events, enables comparisons of patient and clinician reports on treatment toxicity. Methods: In a multisite study of women receiving chemotherapy for early-stage breast cancer, symptom reports were collected on the same day from patients and their clinicians for 17 symptoms; their data were not shared with each other. The proportions of moderate, severe, or very severe patient-reported symptom severity were compared with the proportions of clinician-rated grade 2, 3, or 4 toxicity. Patient-clinician agreement was assessed via κ statistics. Chi-square tests investigated whether patient characteristics were associated with patient-clinician agreement. Results: Among 267 women, the median age was 58 years (range, 24-83 years), and 26% were nonwhite. There was moderate scoring agreement (κ = 0.413-0.570) for 53% of symptoms, fair agreement for 41% (κ = 0.220-0.378), and slight agreement for 6% (κ = 0.188). For example, patient-reported and clinician-rated percentages were 22% and 8% for severe or very severe fatigue, 41% and 46% for moderate fatigue, 32% and 39% for mild fatigue, and 6% and 7% for none. Clinician severity scores were lower for nonwhite patients in comparison with white patients for peripheral neuropathy, nausea, arthralgia, and dyspnea. Conclusions: Although clinician reporting of symptoms is common practice in oncology, there is suboptimal agreement with the gold standard of patient self-reporting. These data provide further evidence supporting the integration of patient-reported outcomes into oncological clinical research and clinical practice to improve monitoring of symptoms as well as timely interventions for symptoms

Patient-reported treatment toxicity and adverse events in Black and White women receiving chemotherapy for early breast cancer

Purpose: It is not known whether chemotherapy-related symptom experiences differ between Black and White women with early breast cancer (Stage I–III) receiving current chemotherapy regimens and, in turn, influences dose delay, dose reduction, early treatment discontinuation, or hospitalization. Methods: Patients self-reported their race and provided symptom reports for 17 major side effects throughout chemotherapy. Toxicity and adverse events were analyzed separately for anthracycline and non-anthracycline regimens. Fisher’s exact tests and two-sample t-tests compared baseline patient characteristics. Modified Poisson regression estimated relative risks of moderate, severe, or very severe (MSVS) symptom severity, and chemotherapy-related adverse events.Please check and confirm that the authors and their respective affiliations have been correctly identified and amend if necessary.no changes Results: In 294 patients accrued between 2014 and 2020, mean age was 58 (SD13) and 23% were Black. For anthracycline-based regimens, the only significant difference in MSVS symptoms was in lymphedema (41% Black vs 20% White, p =.04) after controlling for axillary surgery. For non-anthracycline regimens, the only significant difference was MSVS peripheral neuropathy (41% Blacks vs. 23% White) after controlling for taxane type (p =.05) and diabetes (p =.05). For all other symptoms, severity scores were similar. Dose reduction differed significantly for non-anthracycline regimens (49% Black vs. 25% White, p =.01), but not for anthracycline regimens or in dose delay, early treatment discontinuation, or hospitalization for either regimen. Conclusion: Except for lymphedema and peripheral neuropathy, Black and White patients reported similar symptom severity during adjuvant chemotherapy. Dose reductions in Black patients were more common for non-anthracycline regimens. In this sample, there were minimal differences in patient-reported symptoms and other adverse outcomes in Black versus White patients

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

Patient-Reported Toxicities During Chemotherapy Regimens in Current Clinical Practice for Early Breast Cancer

Background: This study explores the incidence of patient-reported major toxicity—symptoms rated “moderate,” “severe,” or “very severe”—for chemotherapy regimens commonly used in early breast cancer. Patients and Methods: Female patients aged 21 years or older completed a validated Patient-Reported Symptom Monitoring instrument and rated 17 symptoms throughout adjuvant or neoadjuvant chemotherapy. Fisher's exact tests compared differences in percentages in symptom ratings, and general linear regression was used to model the incidence of patient-reported major toxicity. Results: In 152 patients, the mean age was 54 years (range, 24–77), and 112 (74%) were white; 51% received an anthracycline-based regimen. The proportion of patients rating fatigue, constipation, myalgia, diarrhea, nausea, peripheral neuropathy, and swelling of arms or legs as a major toxicity at any time during chemotherapy varied significantly among four chemotherapy regimens (p <.05). The mean (SD) number of symptoms rated major toxicities was 6.3 (3.6) for anthracycline-based and 4.4 (3.5) for non-anthracycline-based regimens (p =.001; possible range, 0–17 symptoms). Baseline higher body mass index (p =.03), patient-reported Karnofsky performance status ≤80 (p =.0003), and anthracycline-based regimens (p =.0003) were associated with greater total number of symptoms rated major toxicities (alternative model: chemotherapy duration, p <.0001). Twenty-six percent of dose reductions (26 of 40), 75% of hospitalizations (15 of 20), and 94% of treatment discontinuations (15 of 16) were in anthracycline-based regimens. Conclusion: Capturing multiple toxicity outcomes throughout chemotherapy enables oncologists and patients to understand the range of side effects as they discuss treatment efficacies. Continuous symptom monitoring may aid in the timely development of interventions that minimize toxicity and improve outcomes. Implications for Practice: This study investigated patient-reported toxicities for 17 symptoms recorded prospectively during adjuvant and neoadjuvant chemotherapy regimens for early breast cancer. An analysis of four commonly used chemotherapy regimens identified significant differences among regimens in both individual symptoms and total number of symptoms rated moderate, severe, or very severe. Longer chemotherapy regimens, such as anthracycline-based regimens followed by paclitaxel, had higher proportions of symptoms rated major toxicities. The inclusion of patient perspectives on multiple toxicity outcomes at the same time at multiple time points during chemotherapy has the potential for improving patient-provider communication regarding symptom management, patient satisfaction, and long-term clinical outcomes

Patient-reported and clinician-reported chemotherapy-induced peripheral neuropathy in patients with early breast cancer: Current clinical practice

Background: In the current study, the authors investigated the incidence of moderate to severe chemotherapy-induced peripheral neuropathy (CIPN) for chemotherapy regimens commonly used in current clinical practice for the treatment of patients with early breast cancer. Patient-reported and clinician-assessed CIPN severity scores were compared, and risk factors for CIPN severity were identified. Methods: Patients completed a Patient-Reported Symptom Monitoring form and oncologists completed a Common Terminology Criteria for Adverse Events form. CIPN reports were collected prospectively during regularly scheduled infusion visits throughout the duration of chemotherapy. Results: The sample included 184 women with a mean age of 55 years; approximately 73% were white. The 4 chemotherapy regimens used were doxorubicin and cyclophosphamide plus paclitaxel (60 patients); docetaxel and cyclophosphamide (50 patients); docetaxel, carboplatin, and anti–human epidermal growth factor receptor 2 (HER2) (24 patients); and doxorubicin and cyclophosphamide plus paclitaxel and carboplatin (18 patients). All patients treated with doxorubicin and cyclophosphamide plus paclitaxel and doxorubicin and cyclophosphamide plus paclitaxel and carboplatin received paclitaxel; all patients treated with docetaxel and cyclophosphamide and docetaxel, carboplatin, and anti-HER2 received docetaxel. The chemotherapy dose was reduced in 52 patients (28%); in 15 patients (29%), this reduction was due to CIPN. Chemotherapy was discontinued in 26 patients (14%), 8 because of CIPN. Agreement between patient-reported and clinician-assessed CIPN severity scores was minimal (weighted Cohen kappa, P =.34). Patient-reported moderate to severe CIPN was higher for paclitaxel (50%) compared with docetaxel (17.7%) (P <.001). Pretreatment arthritis and/or rheumatism (relative risk [RR], 1.58; 95% CI, 1.06-2.35 [P =.023]) and regimens containing paclitaxel (RR, 2.88; 95% CI, 1.72-4.83 [P <.0001]) were associated with higher CIPN severity. Being married (RR, 0.57; 95% CI, 0.37-0.887 [P =.01]) was found to be associated with lower CIPN severity. Conclusions: The discrepancy between patient-reported and clinician-assessed CIPN underscores the need for both patient and clinician perspectives regarding this common, dose-limiting, and potentially disabling side effect of chemotherapy
