RESUMO

PURPOSE: We sought to understand the attitudes of individuals with abnormal breast imaging findings prompting a diagnostic breast biopsy toward donation of blood, excised tissue, or percutaneous biospecimens for research, and to understand medical oncologists' attitudes toward research biospecimen collection in this population. METHODS: We included individuals who presented to a single academic medical center for a clinically indicated, image-guided, percutaneous breast biopsy. We administered a survey prior to knowledge of biopsy results to assess willingness to consider, entirely for research purposes, donating blood or excess excised breast tissue, or having additional biospecimens (AB) obtained during a clinically indicated percutaneous biopsy. We also surveyed breast medical oncologists from National Cancer Institute-designated cancer centers to assess attitudes toward approaching patients for biospecimen research. RESULTS: Overall, 53/63 patients responded to the survey; 70% would consider donating blood, 85% would consider donating excess excised breast tissue, and 32% would consider having AB obtained during a clinically indicated biopsy. Main motivating factors for considering AB included contributing to scientific knowledge and return of study or biopsy results, whereas anxiety and the potential discomfort were the main dissuading factors. Among 191 medical oncologists, most were very comfortable (59.2%), or somewhat comfortable (32.5%) asking patients to have AB obtained during a clinically indicated breast biopsy. Medical oncologists reported hesitancy to refer a patient for AB due to potential pain/discomfort, and other procedure risks. CONCLUSIONS: Only one-third of individuals with breast imaging findings would consider consenting to AB during a diagnostic biopsy, whereas most were open to donating blood or excess excised breast tissue. Most medical oncologists would be comfortable asking patients to have AB obtained during the biopsy. Understanding patients' and oncologists' baseline attitudes may inform the design and approach to breast biospecimen-based research.

RESUMO

BACKGROUND: The objective of this study was to describe the perspective of patients with early breast cancer toward research biopsies. The authors hypothesized that more patients at academic sites than at community-based sites would be willing to consider these procedures. METHODS: In total, 198 patients with early stage breast cancer were recruited from 3 academic centers (n = 102) and from 1 community oncology practice (n = 96). The primary objective was to compare the proportion of patients willing to consider donating excess tissue biospecimens from surgery, from a clinically indicated breast biopsy, or from a research purposes-only biopsy (RPOB) between practice types. RESULTS: Most patients (93% at academic sites, 94% at the community oncology site) said they would consider donating excess tissue from surgery for research. One-half of patients from academic or community sites would consider donating tissue from a clinically indicated breast biopsy. On univariate analysis, significantly fewer patients from academic sites would consider an RPOB (22% at academic sites, 42% at the community site; P = .003); however, this difference was no longer significant on multivariate analysis (P = .96). Longer transportation times and unfavorable prior experiences were associated with less willingness to consider an RPOB on multivariate analysis. Significantly fewer patients from academic sites (14%) than from the community site (35%) would consider a research biopsy in a clinical trial (P = .04). Contributing to scientific knowledge, return of results, and a personal request by their physician were the strongest factors influencing patients' willingness to undergo research biopsies. CONCLUSIONS: The current results rejected the hypothesis that more patients with early breast cancer at academic sites would be willing to donate tissue biospecimens for research compared with those at community oncology sites. These findings identify modifiable factors to consider in biobanking studies and clinical trials.

RESUMO

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.

RESUMO

BACKGROUND: Young adults with cancer experience disruptions in their normal developmental trajectories and commonly experience psychologic distress related to their diagnoses. Young women with metastatic breast cancer (MBC) are at particular risk of adverse mental health outcomes. OBJECTIVE: We sought to determine the prevalence of and factors associated with anxiety and depression symptoms in young women with newly diagnosed de novo MBC. METHODS: A total of 54 women with newly diagnosed de novo MBC were identified from an ongoing, prospective, multicenter cohort of women diagnosed with breast cancer at age <40. Depression and anxiety symptoms were assessed using the Hospital Anxiety and Depression Scale (HADS). Items assessing socio-demographics, physical symptom burden, social support, and disease and treatment history, with complementary medical record review, were used to assess variables potentially associated with anxiety and depression symptoms. RESULTS: Mean HADS Depression score was 4.4 (standard deviation = 3.7) and mean HADS Anxiety score was 7.9 (standard deviation = 5.0). Eleven (20%) women scored ≥8 on the HADS Depression subscale, the suggested threshold for depression/anxiety screening, and 24 (44%) women scored ≥8 on the HADS Anxiety subscale. In a multivariable model of anxiety, higher physical symptom scores (odds ratio = 4.41, p = 0.005) was significantly associated with higher anxiety scores. None of the other variables improved the model fit. CONCLUSION: In this study, a considerable proportion of young women with newly diagnosed MBC experienced anxiety symptoms, although depression was less common. Future strategies focused on distress reduction in young MBC patients should focus on physical symptom management as well as anxiety identification and management.

RESUMO

BACKGROUND: Intravenous lidocaine is effective in treating pain. Limited studies have assessed the effectiveness and safety of subcutaneous lidocaine infusions. METHODS: We conducted a retrospective review of patients with cancer who received subcutaneous lidocaine infusions for pain. Patient characteristics, pain scores and opioid doses before and after lidocaine, and details of infusions were recorded. We identified three time periods of interest. T0 is defined as the 24-hour period immediately before commencing lidocaine treatment. T1 is defined as the 24-hour period before lidocaine was ceased. T2 is defined as the first 24-hour period after lidocaine was ceased. In addition, the overall impression of the effectiveness of lidocaine was subjectively evaluated by the authors. RESULTS: Twenty patients (13M;7F) received lidocaine. Two patients received it twice, totaling 22 episodes. The median lidocaine dose was 0.67 mg/kg/h with the median duration being 5.5 days. The median worst pain score at T0 and T1 was 8.5 and 5.5, respectively. The difference in the mean pain scores was 3.2 95% CI (2.1, 4.4; p < 0.001). In 15/22 episodes (68%), patients experienced a decrease in pain scores of more than 2. The median morphine oral equivalent (MOE) daily doses at T0, T1, and T2 were 425, 362.5, and 275 mg, respectively. The difference in the mean MOE between T0 and T1 was -126 (95% CI [-281, 28]; p = 0.13). The difference in the mean MOE between T0 and T2 was -207 (95% CI [-370, -44]; p = 0.025). Lidocaine was subjectively deemed effective in 10/22 episodes (45%). There were no documented adverse events attributed to lidocaine. Univariate analyses did not identify any subgroups likely to benefit from lidocaine. CONCLUSION: Subcutaneous lidocaine infusions may be used safely in cancer pain management and is effective in some patients.

RESUMO

BACKGROUND: Tissue from research biopsies provides access to insights into tumor biology. We aimed to determine medical oncologists' (MOs') attitudes toward research biopsies in patients with metastatic breast cancer (MBC). MATERIALS AND METHODS: A total of 309 breast MOs from National Cancer Institute (NCI)-designated cancer centers were invited to complete a self-administered survey about their attitudes toward approaching patients for research purpose-only biopsies (RPOBs), performed as a standalone procedure, or additional biopsies, performed with a clinically indicated biopsy. The MOs were asked to predict what proportion of their MBC patients would consider undergoing research biopsies. RESULTS: Of the 309 MOs, 221 (72%) responded. Of these 221 MOs, 30 were ineligible, leaving 191 eligible responders. Nearly all the MOs reported they were comfortable approaching patients regarding research biopsies of blood or skin. One fifth of MOs were uncomfortable approaching patients for RPOBs of the breast. One half of MOs were uncomfortable approaching patients for RPOBs of the liver. A significant variation was found in the perceptions by MOs of their patients' willingness to undergo research biopsies. The factors associated with increased comfort in approaching patients for research biopsies included fewer years in practice, caring for patients who had undergone recent research biopsies, and the predicted willingness of patients to consent to biopsies. The risk of a biopsy and biopsy-related pain were the most common reasons for reluctance to refer patients for research biopsies. CONCLUSION: Significant variation exists, even at NCI centers, in the comfort level of MOs in approaching MBC patients for research biopsies. MOs' attitudes toward research biopsies might be a modifiable factor in increasing tissue collection for research. IMPLICATIONS FOR PRACTICE: Tissue-based research is critical in advancing our understanding of cancer biology, and obtaining tissue from a research biopsy provides an essential resource. This study demonstrates the variability of oncologists' attitudes toward research biopsies and elicits factors associated with increased comfort levels with approaching patients for research biopsies. Biopsy risk and biopsy-related pain were commonly cited reasons not to refer patients for research biopsies. If the risk of a research biopsy is deemed sufficiently low enough to be acceptable, oncologists' attitudes might be a potential target for education and change, which may assist in increasing the availability of tissue for cancer research.

RESUMO

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.

RESUMO

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.

RESUMO

The provision of health services in Australia currently is primarily financed by a unique interaction of public and private insurers. This commentary looks at a loophole in this framework, namely that private insurers have to date been able to avoid funding healthcare for some of their policy holders, as it is not a requirement to use private insurance when treatment occurs in Australian public hospitals.
