Background: Breast cancer subtypes are associated with distinct metastatic patterns. Whether germline BRCA1/BRCA2 mutation status is independently associated with central nervous system (CNS) relapse, controlling for tumor subtype, is unknown.Methods: Patients who were treated at Dana‐Farber Cancer Institute and diagnosed with a first locoregional recurrence (LRR) or metastasis between 1981 and 2014 were identified using 2 institutional registries: 1) patients treated for recurrent breast cancer and 2) patients who underwent BRCA testing. The frequencies of LRR, sites of metastasis, and breast cancer‐specific survival from LRR or metastasis were calculated, and the factors associated with CNS recurrence were evaluated using multivariable logistic regression models.Results: The final study cohort included 30 BRCA1 mutation carriers, 32 BRCA2 mutation carriers, and 270 noncarriers. Most BRCA1 carriers (73%) had triple‐negative breast cancer; whereas most BRCA2 carriers (72%) had hormone receptor‐positive tumors. BRCA1 carriers frequently experienced lung and distant lymph node metastasis, whereas BRCA2 carriers and noncarriers most often experienced bone metastasis. Although CNS disease occurred frequently in both BRCA1 and BRCA2 carriers (53% BRCA1, 50% BRCA2, 25% noncarriers; P < .001), only BRCA2 mutation (P = .006) was significantly associated with CNS metastasis in multivariable analysis controlling for tumor subtype. BRCA2 mutation (P = .01), triple‐negative subtype (P < .001), and the involvement of CNS (P < .001) and other non‐CNS distant sites (relative to locoregional recurrence or contralateral disease; P < .001) at presentation of recurrent breast cancer were associated with risk for mortality.Conclusions: CNS involvement is frequent in women with germline BRCA1/BRCA2 mutations who have metastatic breast cancer. BRCA2 mutation carriers had a significantly higher frequency of CNS metastasis than noncarriers when controlling for breast cancer subtype.

Palliative care is a fundamental component of cancer care. As part of the 2011 to 2012 Leadership Development Program (LDP) of the American Society of Clinical Oncology (ASCO), a group of participants was charged with advising ASCO on how to develop a service model integrating palliative care throughout the continuum of cancer care. This article presents the findings of the LDP group. The group focused on the process of palliative care delivery in the oncology setting. We identified key elements for models of palliative care in various settings to be potentially equitable, sustainable, feasible, and acceptable, and here we describe a dynamic model for the integrated, simultaneous implementation of palliative care into oncology practice. We also discuss critical considerations to better integrate palliative care into oncology, including raising consciousness and educating both providers and the public about the importance of palliative care; coordinating palliative care efforts through strengthening affiliations and/or developing new partnerships; prospectively evaluating the impact of palliative care on patient and provider satisfaction, quality improvement, and cost savings; and ensuring sustainability through adequate reimbursement and incentives, including linkage of performance data to quality indicators, and coordination with training efforts and maintenance of certification requirements for providers. In light of these findings, we believe the confluence of increasing importance of incorporation of palliative care education in oncology education, emphasis on value-based care, growing use of technology, and potential cost savings makes developing and incorporating palliative care into current service models a meaningful goal.

Benefits of chemotherapy vary in patients with metastatic breast cancer (MBC). This article describes the impact of tumor subtype and the line of therapy on the duration of chemotherapy. Clinicopathologic characteristics were extracted from the medical records of 199 consecutive patients with MBC at Dana-Farber Cancer Institute and analyzed according to subtype. Tumor subtypes were classified as hormone receptor (HR)-positive, triple-negative (TNBC), or HER2-amplified breast cancer. Duration of chemotherapy of each line was defined as the start of a chemotherapy regimen to the start of the next line of therapy as a result of progression or toxicity. There were 96, 44, and 59 patients with HR+, TNBC, and HER2-amplified breast cancer, respectively. Median age at MBC diagnosis was 53 years. Median overall survivals were 32 and 54 months for HER2-amplified disease, 36 months for HR+ breast cancer, and 17 months for TNBC (P<.0001). Patients with HER2-amplified disease received the most lines (median, 4; P=.032) and the longest duration of chemotherapy for every line. The median duration of chemotherapy in HER2-amplified patients remained at more than 4 months even out to sixth-line therapy. Patients with TNBC tended to receive the shortest duration of chemotherapy for every line of therapy. Tumor subtypes influence the number of lines, duration of chemotherapy, and survival. Among patients with HR+ and HER2-amplified disease who undergo chemotherapy beyond the third line, substantial rates of prolonged therapies suggest clinical benefit. The role of advanced (greater than third) chemotherapy lines in improving survival of all patients with MBC warrants further study.

Spiritual care is integral to palliative care. It engenders a sense of purpose, meaning, and connectedness to the sacred or important and may support caregiver well-being. To examine caregivers’ spirituality, religiosity, spiritual well-being, and views on spiritual/religious support. A mixed-methods study across 4 Australian sites, recruiting caregivers of patients with a life expectancy of under 12 months. The anonymous semistructured questionnaire used included research team developed and adapted questions examining religion/spirituality’s role and support and views on hospitals supporting spiritual/religious requirements. It additionally included the Functional Assessment of Chronic Illness Therapy-Spiritual Well-Being Scale (FACIT-Sp-12). One hundred nine caregivers participated (47.4% responded). Median spiritual well-being was 30.5 on FACIT-Sp-12. Religious affiliation was associated with higher Faith subscores (P < .001). Spirituality was very important to 24.5%, religiosity to 28.2%, and unimportant to 31.4% and 35.9%, respectively. Caregivers prayed (P = .005) and meditated (P = .006) more following patients’ diagnoses, gaining comfort, guidance, and strength. Caregivers whose spiritual/religious needs were met to moderate/full extent by external religious/faith communities (23.8%) reported greater spiritual well-being (P < .001). Hospitals supported moderate/full caregiver spiritual needs in 19.3%. Pastoral care visits comforted 84.4% of those who received them (n = 32) but elicited discomfort in 15.6%. Caregivers also emphasized the importance of humane staff and organizational tone in supporting spiritual care. Hospital-based spiritual care providers should seek to identify those who seek pastoral or religiously orientated care. Genuine hospitality of showing concern for the other ensures the varied yet inevitably humanist requirements of the caregiver community are met.

Research studies involving human tissue are increasingly common. However, patients' attitudes toward research biopsies are not well characterized, particularly when the biopsies are carried out outside the context of therapeutic trials. One hundred sixty patients with metastatic breast cancer (MBC) from two academic (n = 80) and two community (n = 80) hospitals completed a 29-item self-administered survey to evaluate their willingness to consider providing research purposes only biopsies (RPOBs) (as a stand-alone procedure) and additional biopsies (ABs) (additional needle passes at the time of a clinically indicated biopsy). Eighty-two (51%) of 160 patients would consider having RPOBs, of which 42 (53%) and 40 (50%) patients were from academic and community hospitals, respectively. Patients who had more prior biopsies were less likely to consider RPOBs (RR = 0.6, 95% CI: 0.4–1.0, P = 0.03). Of 160 patients, 115 (72%) patients would consider having ABs. Of these, 64 (80%) and 51 (64%) patients from academic and community hospitals, respectively, would consider ABs (RR = 1.2, 95% CI: 1.0–1.5, P = 0.03). Many patients with MBC in both academic and community settings report willingness to consider undergoing biopsies for research. Further research is needed to understand ethical, logistical and provider-based barriers to broader participation in such studies.
