Nivolumab with chemotherapy as neoadjuvant treatment for inflammatory breast cancer

e12633

Background: Inflammatory breast cancer (IBC) is the most aggressive form of breast cancer with poor prognosis and is often resistant to neoadjuvant systemic therapy with early recurrence and metastases. PD-L1 expression in IBC is moderate to high, and blockade of the PD-1/PD-L1 axis with checkpoint inhibitors has emerged as a promising treatment to enhance clinical response. We examined the efficacy of neoadjuvant nivolumab (anti-PD-1 antibody) with chemotherapy in IBC. Methods: This is an open-label multicohort multicenter study of nivolumab with neoadjuvant chemotherapy in patients with newly diagnosed non-metastatic IBC (n=52). All breast cancer subtypes (ER/PR/HER2) were allowed. Patients received nivolumab 360 mg on day 1 (21-day cycle) x 4 cycles with standard chemotherapy. Cohort 1 (HER2-negative) received nivolumab with paclitaxel (80 mg/m2)x12 weeks followed by doxorubicin (60 mg/m2) and cyclophosphamide (600 mg/m2) (AC) x 4 cycles. Cohort 2 (HER2-positive) received nivolumab with taxane (paclitaxel 80 mg/m2, docetaxel 75 mg/m2, or nab-paclitaxel 100 mg/m2), trastuzumab (8 mg/kg then 6 mg/kg), and pertuzumab (840 mg then 420 mg) x 4 cycles followed by AC x 4 cycles. All patients underwent modified radical mastectomy (MRM) followed by radiation and adjuvant therapy per institutional standard of care. Primary objective was pathologic complete response (pCR) (ypT0/Tis ypN0). Residual Cancer Burden (RCB) was assessed. Secondary objectives were safety/tolerability and invasive recurrence-free interval at 2 years. Breast biopsies, residual tumor tissue, and peripheral blood samples were collected for correlative biomarker testing. PD-L1 expression in tumor tissue will be assessed as a predictive marker. Study was closed after 8 patients were enrolled due to slow accrual. Results: 8 patients were enrolled from June 2019-December 2020. All completed neoadjuvant systemic therapy with nivolumab and none had disease progression. They underwent MRM between January 2020-June 2021. Mean age was 57 years (range 43-74). 4 were HER2-positive, 3 were TNBC, and 1 was HR-positive/HER2-negative. 3 were Caucasian, 2 were Latino, 2 were Black, and 1 was Asian. There was no grade 4 toxicity. Most common grade 3 toxicity was neutropenia (n=3). Immune-related events were diarrhea/colitis (n=2) and elevated liver transaminases (n=1). At time of MRM, 4 patients had pCR, 1 had RCB-I, 2 had RCB-II, and 1 had RCB-III. They remain with no evidence of disease and are in follow-up. Tumor biological correlatives are being performed. Conclusions: Addition of nivolumab to neoadjuvant therapy was tolerable and safe and demonstrated anti-tumor activity in IBC with high pCR rate in this pilot study. This supports further investigation of the role of checkpoint inhibitors in treatment of IBC. Clinical trial information: NCT03742986. [Table: see text]

Relations of Mindfulness and Illness Acceptance With Psychosocial Functioning in Patients With Metastatic Breast Cancer and Caregivers

OBJECTIVES

To examine relationships in mindfulness and illness acceptance and psychosocial functioning in patients with metastatic breast cancer and their family caregivers.

SAMPLE & SETTING

33 dyads from an academic cancer center in the United States.

METHODS & VARIABLES

Participants completed questionnaires on mindfulness, illness acceptance, relationship quality, anxiety, and depressive symptoms. Dyadic, cross-sectional data were analyzed using actor-partner interdependence models.

RESULTS

Greater nonjudging, acting with awareness, and illness acceptance among caregivers were associated with patients' and caregivers' perceptions of better relationship quality. Higher levels of these processes were associated with reduced anxiety and depressive symptoms in patients and caregivers.

IMPLICATIONS FOR NURSING

Aspects of mindfulness and illness acceptance in dyads confer benefits that are primarily intrapersonal in nature. Nurses may consider introducing mindfulness and acceptance-based interventions to patients and caregivers with adjustment difficulties.

Protocol of a randomized trial of acceptance and commitment therapy for fatigue interference in metastatic breast cancer

Fatigue interference with activities, mood, and cognition is one of the most prevalent and distressing concerns of metastatic breast cancer patients. To date, there are no evidence-based interventions for reducing fatigue interference in metastatic breast cancer and other advanced cancer populations. In pilot studies, Acceptance and Commitment Therapy (ACT) has shown potential for reducing symptom-related suffering in cancer patients. The current Phase II trial seeks to more definitively examine the efficacy of telephone-based ACT for women with metastatic breast cancer who are experiencing fatigue interference. In this trial, 250 women are randomly assigned to either the ACT intervention or an education/support control condition. Women in both conditions attend six weekly 50-min telephone sessions. The primary aim of this study is to test the effect of telephone-based ACT on fatigue interference. Secondary outcomes include sleep interference, engagement in daily activities, and quality of life. Outcomes are assessed at baseline, 2 weeks post-intervention, and 3 and 6 months post-intervention. This trial also examines whether increases in psychological flexibility, defined as full awareness of the present moment while persisting in behaviors aligned with personal values, account for the beneficial effect of ACT on fatigue interference. After demonstrating ACT's efficacy, the intervention can be widely disseminated to clinicians who care for metastatic breast cancer patients. Our findings will also inform future ACT trials with various cancer populations and functional outcomes.

Oncology fellows’ knowledge and current practice regarding outpatient oncology and palliative care

10527

Background: Patients with advanced cancers often suffer from a number of symptoms and need guidance when discussing treatment goals as their diseases’ progress. Palliative care competencies include the assessment and management of both physical and psychological symptoms, as well as, the conduct of goals of care conversations and advanced care planning. Palliative medicine is subspecialty that specially addresses these needs in patients with advanced cancers, but is not universally available. Oncology fellowship training must include these competencies and there is little evidence regarding the palliative care educational experiences of oncology fellows. This study examines fellows’ experiences with palliative care education and fellows’ attitudes about concurrent palliative care in the outpatient setting. Methods: An electronic nationwide survey of medical oncology fellows was conducted in the second half of the academic year in 2018. Results: 43 of 191, 22.5%, of oncology fellows contacted at 17 institutions responded. 96% of fellows indicated they would strongly agree or agree with having a Palliative Care team in their future outpatient clinics. 93% of fellows agree or strongly agree with being comfortable managing cancer related pain, but only half agree or strongly agree with being comfortable managing depression and anxiety. 91% agree or strongly agree they are comfortable with discussions about transitions to best supportive care, while only 31% of fellows always or often assist patients in completing advance care documents. 70% of fellows are always, often, or sometimes receiving feedback on their communication and symptom management skills. Conclusions: Oncology fellows fell comfortable with some aspects of palliative care more than others. Fellows in this survey report feeling comfortable with goals of care conversations and pain management, but are not as comfortable managing other symptoms like depression and anxiety. Respondents are not universally assisting patients in advanced care documentation and only two-thirds of responding fellows are receiving frequent feedback on their communication and symptom skills. There is a consensus among responding fellows about a desire to have palliative care embedded in their future clinics.

Oncology fellows' current practice regarding concurrent outpatient oncology and palliative care

122

Background: It is accepted that Palliative Care provides additional support and improves overall care to oncology patients. Literature supports early referral and integration of Palliative Care with standard oncology care and is a guideline from the American Society of Clinical Oncology. In order to make palliative care integration a standard of care, Oncology Fellows should be learning to integrate during their fellowship years. There is little information regarding the Palliative Care experience in the outpatient setting for Oncology Fellows in the United States. This study looked at the current practice model in regards to concurrent Oncology and Palliative Care in the outpatient setting. Methods: An electronic nationwide survey of medical Oncology Fellows was conducted in the second half of the academic year in 2018. Results: 43 of 191, 22.5% Fellows contacted at 17 institutions responded. 98% of the fellows’ hospital systems offered ambulatory palliative care with 79% having a palliative care specialist available during their ambulatory Oncology clinic. 55% of the Fellows’ patient referrals are occurring when they still have multiple lines of cancer directed treatment planned, and the most common initial referral reason is for symptom management. 97% of fellows agree or strongly agree that it is appropriate to refer patients to ambulatory Palliative Care while patients are still undergoing active cancer treatment. 95% indicate they would strongly agree or agree with having a Palliative Care team in their future outpatient clinics. Although no participants stated their initial consult request was for psychosocial and/or spiritual support, 95% strongly agreed or agreed that Palliative Care helps ensure these issues are addressed. Conclusions: Early integration of Palliative Care is occurring in the 17 responding institutions around the country as 97% of Fellows agree or strongly agree that it is appropriate to refer patients to ambulatory Palliative Care while patients are still undergoing active cancer treatment. 95% of oncology fellows indicate they would strongly agree or agree with having a Palliative Care team in their future outpatient clinics.

Metastatic breast cancer patients' expectations and priorities for symptom improvement

PURPOSE

Little research has examined cancer patients' expectations, goals, and priorities for symptom improvement. Thus, we examined these outcomes in metastatic breast cancer patients to provide patients' perspectives on clinically meaningful symptom improvement and priorities for symptom management.

METHODS

Eighty women with metastatic breast cancer participated in a survey with measures of comorbidity, functional status, engagement in roles and activities, distress, quality of life, and the modified Patient-Centered Outcomes Questionnaire that focused on 10 common symptoms in cancer patients.

RESULTS

On average, patients reported low to moderate severity across the 10 symptoms and expected symptom treatment to be successful. Patients indicated that a 49% reduction in fatigue, 48% reduction in thinking problems, and 43% reduction in sleep problems would represent successful symptom treatment. Cluster analysis based on ratings of the importance of symptom improvement yielded three clusters of patients: (1) those who rated thinking problems, sleep problems, and fatigue as highly important, (2) those who rated pain as moderately important, and (3) those who rated all symptoms as highly important. The first patient cluster differed from other subgroups in severity of thinking problems and education.

CONCLUSIONS

Metastatic breast cancer patients report differing symptom treatment priorities and criteria for treatment success across symptoms. Considering cancer patients' perspectives on clinically meaningful symptom improvement and priorities for symptom management will ensure that treatment is consistent with their values and goals.

Acceptance and commitment therapy for symptom interference in metastatic breast cancer patients: a pilot randomized trial

PURPOSE

Breast cancer is the leading cause of cancer mortality in women worldwide. With medical advances, metastatic breast cancer (MBC) patients often live for years with many symptoms that interfere with activities. However, there is a paucity of efficacious interventions to address symptom-related suffering and functional interference. Thus, this study examined the feasibility and preliminary efficacy of telephone-based acceptance and commitment therapy (ACT) for symptom interference with functioning in MBC patients.

METHODS

Symptomatic MBC patients (N = 47) were randomly assigned to six telephone sessions of ACT or six telephone sessions of education/support. Patients completed measures of symptom interference and measures assessing the severity of pain, fatigue, sleep disturbance, depressive symptoms, and anxiety.

RESULTS

The eligibility screening rate (64%) and high retention (83% at 8 weeks post-baseline) demonstrated feasibility. When examining within-group change, ACT participants showed decreases in symptom interference (i.e., fatigue interference and sleep-related impairment; Cohen's d range = - 0.23 to - 0.31) at 8 and 12 weeks post-baseline, whereas education/support participants showed minimal change in these outcomes (d range = - 0.03 to 0.07). Additionally, at 12 weeks post-baseline, ACT participants showed moderate decreases in fatigue and sleep disturbance (both ds = - 0.43), whereas education/support participants showed small decreases in these outcomes (ds = - 0.24 and - 0.18 for fatigue and sleep disturbance, respectively). Both the ACT and education/support groups showed reductions in depressive symptoms (ds = - 0.27 and - 0.28) at 12 weeks post-baseline. Group differences in all outcomes were not statistically significant.

CONCLUSIONS

ACT shows feasibility and promise in improving fatigue and sleep-related outcomes in MBC patients and warrants further investigation.
