Advice from one patient to another: Qualitative analysis of patients\u27 perspectives about chemotherapy initiation

PURPOSE: Although the association between delays in (neo)adjuvant chemotherapy initiation and adverse outcomes is well-documented, patient perspective regarding the lived experience among those with breast cancer delay is sparse. Project Start was a qualitative study designed to assess and identify the multilevel factors contributing to the barriers and facilitators of initiating chemotherapy. This report explores specific responses where patients with breast cancer provide insight and advice for newly diagnosed women on preparing for chemotherapy initiation and informs potential interventions to facilitate timely chemotherapy initiation. PATIENTS AND METHODS: Women diagnosed with primary invasive breast cancer who experienced a ≥60-day delay in (neo)adjuvant chemotherapy initiation were included. Participants completed semi-structured interviews exploring barriers and facilitators to starting chemotherapy. Interviews were transcribed and coded to identify themes. RESULTS: We enrolled (N = 22) participants with a median age at diagnosis of 53.5 years (range 27-70) who identified as Latina (n = 8), Black (n = 5), and non-Latina White (n = 9). Our participants indicated that engaging their medical teams and seeking support earlier were essential to initiate their treatment journeys. They emphasized being proactive and thorough in all aspects of their journey, particularly in processing medical recommendations, communicating with medical personnel, and identifying areas of need. Although explicit insight into chemotherapy delay was rare, participants expressed the importance of beginning treatment promptly. They shared advice on acquiring support (eg, financial, emotional, logistical, spiritual) and suggested connecting with breast cancer survivors to overcome the complex challenges of cancer care. CONCLUSION: Patient perspectives regarding barriers and treatment facilitators help provide insight into the lived experience of cancer care journeys that can inform interventions to improve patient support and outcomes. We are using these results to develop a pilot study to test the acceptability and feasibility of a culturally tailored patient navigation intervention to increase self-efficacy and avoid treatment delays

Real-World Patterns of Everolimus Use in Patients with Metastatic Breast Cancer

© AlphaMed Press 2020 Background: There is limited literature on patterns of everolimus use and subsequent hospitalizations and emergency room (ER) visits in real-world clinical practice. In this study, we describe patterns of everolimus use and hospitalizations and ER visits in a large cohort of patients with breast cancer (BC). Materials and Methods: Patients with BC treated with everolimus were identified in the MarketScan database from 2009 to 2016. The pattern of everolimus use and frequency of associated ER visits and hospitalizations during treatment (between the first claim and 30 days after the last claim for everolimus) were identified. Descriptive statistics and regression models were used. Results: A total of 3,556 everolimus users were identified (median age of 60 years; median days of use, 112). The initial prescribed dose was 10 mg in 74.8% of the patients. Compared with the initial dose, 23.5% of patients had a dose change. Forty-six percent of patients were hospitalized or had an ER visit during the treatment with everolimus. Age greater than 71, higher comorbidity score, treatment year prior to 2012, and lower initial dose were found to be significantly associated with ER visit/hospitalization in the regression models. Conclusions: A significant proportion of patients receiving everolimus had an ER visit or hospitalization during the use of everolimus. These results provide data regarding risks and benefits of treatment with everolimus. These results will be helpful in identifying patients at higher risk of hospitalizations or ER visits and facilitate evidence-based decision making to avoid serious complications. Implications for Practice: Everolimus, a mammalian target of rapamycin inhibitor, is approved in combination with exemestane in patients with hormone receptor–positive tumors previously treated with anastrozole or letrozole. As new drugs become available, it is crucial to understand the adverse events and potential complications associated with the use of such drugs in the general population, outside of the controlled clinical trial setting. This study describes the patterns of everolimus use and adverse events, including hospitalization and emergency room visits, in a large cohort of patients with metastatic breast cancer in routine practice

Movement through chemotherapy delay to initiation among breast cancer patients: A qualitative analysis

Purpose: (Neo) adjuvant chemotherapy decreases the risk of recurrence and improves overall survival among breast cancer patients; however, delays in chemotherapy initiation are associated with adverse health outcomes. The causes of delay are complex and include interrelated social, economic, cultural, environmental, and health system factors. Project Start was a qualitative study designed to assess and identify the multilevel factors contributing to the barriers and facilitators of initiating chemotherapy. Patients and Methods: Women diagnosed with primary invasive breast cancer who experienced ≥60 day delay in (neo) adjuvant chemotherapy initiation were included. Participants completed semi-structured interviews exploring barriers and facilitators to starting chemotherapy. Interviews were transcribed and coded to identify themes using the Results: We enrolled (N=22) participants with median age at diagnosis 53.5 years (range 27-70) who identified as Latina (n=8), Black (n=5), and non-Latina White (n=9). Participants described a common chemotherapy initiation process reflecting their unique needs as they transitioned through four stages: 1) receiving diagnosis and treatment recommendations; 2) processing treatment options; 3) Flipping the Switch ; and 4) activating treatment and engaging in care. Limited explicit insight into their chemotherapy delay was expressed. Engagement across the self-, family-, community-, and medical-realms revealed interlinked and pivotal sources of support that helped participants navigate toward initiating chemotherapy. Specifically, the overarching themes included logistical, emotional, financial, and social sources of support and the relationship of these sources of support to participants\u27 perceived self-efficacy to move toward initiating treatment. Conclusion: Activating women to be engaged in the treatment process across multiple levels appeared to facilitate initiating chemotherapy. Multilevel interventions that engage the patient, family, community, and medical team may support the initiation of timely chemotherapy

Functional consequence of the MET-T1010I polymorphism in breast cancer.

Major breast cancer predisposition genes, only account for approximately 30% of high-risk breast cancer families and only explain 15% of breast cancer familial relative risk. The HGF growth factor receptor MET is potentially functionally altered due to an uncommon germline single nucleotide polymorphism (SNP), MET-T1010I, in many cancer lineages including breast cancer where the MET-T1010I SNP is present in 2% of patients with metastatic breast cancer. Expression of MET-T1010I in the context of mammary epithelium increases colony formation, cell migration and invasion in-vitro and tumor growth and invasion in-vivo. A selective effect of MET-T1010I as compared to wild type MET on cell invasion both in-vitro and in-vivo suggests that the MET-T1010I SNP may alter tumor pathophysiology and should be considered as a potential biomarker when implementing MET targeted clinical trials

Phase II trial of AKT inhibitor MK-2206 in patients with advanced breast cancer who have tumors with PIK3CA or AKT mutations, and/or PTEN loss/PTEN mutation

Background The PI3K/AKT pathway is activated through PIK3CA or AKT1 mutations and PTEN loss in breast cancer. We conducted a phase II trial with an allosteric AKT inhibitor MK-2206 in patients with advanced breast cancer who had tumors with PIK3CA/AKT1 mutations and/or PTEN loss/mutation. Methods The primary endpoint was objective response rate (ORR). Secondary endpoints were 6-month progression-free survival (6 m PFS), predictive and pharmacodynamic markers, safety, and tolerability. Patients had pre-treatment and on-treatment biopsies as well as collection of peripheral blood mononuclear cells (PBMC) and platelet-rich plasma (PRP). Next-generation sequencing, immunohistochemistry, and reverse phase protein arrays (RPPA) were performed. Results Twenty-seven patients received MK-2206. Eighteen patients were enrolled into the PIK3CA/AKT1 mutation arm (cohort A): 13 had PIK3CA mutations, four had AKT1 mutations, and one had a PIK3CA mutation as well as PTEN loss. ORR and 6 m PFS were both 5.6% (1/18), with one patient with HR+ breast cancer and a PIK3CA E542K mutation experiencing a partial response (on treatment for 36 weeks). Nine patients were enrolled on the PTEN loss/mutation arm (cohort B). ORR was 0% and 6 m PFS was 11% (1/9), observed in a patient with triple-negative breast cancer and PTEN loss. The study was stopped early due to futility. The most common adverse events were fatigue (48%) and rash (44%). On pre-treatment biopsy, PIK3CA and AKT1 mutation status was concordant with archival tissue testing. However, two patients with PTEN loss based on archival testing had PTEN expression on the pre-treatment biopsy. MK-2206 treatment was associated with a significant decline in pAKT S473 and pAKT T308 and PI3K activation score in PBMC and PRPs, but not in tumor biopsies. By IHC, there was no significant decrease in median pAKT S473 or Ki-67 staining, but a drop was observed in both responders. Conclusions MK-2206 monotherapy had limited clinical activity in advanced breast cancer patients selected for PIK3CA/AKT1 or PTEN mutations or PTEN loss. This may, in part, be due to inadequate target inhibition at tolerable doses in heavily pre-treated patients with pathway activation, as well as tumor heterogeneity and evolution in markers such as PTEN conferring challenges in patient selection.
