RESUMEN

PURPOSE OF REVIEW: In this Perspective we share the personal story of a 33-year-old patient diagnosed with metastatic breast cancer and her journey through fertility preservation, surrogacy, and eventually motherhood, highlighting misconceptions about fertility preservation in this population. RECENT FINDINGS: There are nearly 1 million women under the age of 50 diagnosed and living with cancer in the USA. These patients are met with life-altering decisions, including those that may limit their reproductive ability. While there have been tremendous advances and advocacy in the field of oncofertility, there has been limited focus on patients with advanced stage or metastatic cancer. We describe five key misconceptions surrounding fertility preservation in patients with advanced stage cancer, offering a review of the literature and our approach to challenging topics like desiring fertility preservation in the face of Stage 4 disease, the safety and timing of ovarian stimulation during cancer treatment, and passing away following fertility preservation. We review the importance of assessing perceptions of fertility preservation in patients with metastatic cancer and highlight the lack of research in this area as a call to action.

RESUMEN

BACKGROUND: Breast cancer patients experienced heightened anxiety during the pandemic. Also, modifications to clinical trial activities allowing for virtual platforms, local assessments, and greater flexibility were introduced to facilitate participation. We sought to evaluate the association between pandemic-related anxiety and willingness to participate in trials and how pandemic-era modifications to trial activities affect the decision to participate. METHODS: We conducted an online survey from August to September, 2021 of patients with breast cancer assessing pandemic-related anxiety; clinical trials knowledge and attitudes; willingness to participate during and before the pandemic; and how each modification affects the decision to participate. Fisher's exact tests evaluated differences in proportions and two-sample t-tests evaluated differences in means. The association of pandemic-related anxiety with a decline in willingness to participate during compared to prior to the pandemic was modeled using logistic regression. RESULTS: Among 385 respondents who completed the survey, 81% reported moderate-severe pandemic-related anxiety. Mean willingness to participate in a trial was lower during the pandemic than prior [2.97 (SD 1.17) vs. 3.10 (SD 1.09), (p < 0.001)]. Severe anxiety was associated with higher odds of diminished willingness to participate during the pandemic compared to prior (OR 5.07). Each of the modifications, with the exception of opting out of research-only blood tests, were endorsed by >50% of respondents as strategies that would increase their likelihood of deciding to participate. CONCLUSIONS: While pandemic-related anxiety was associated with diminished willingness to participate in trials, the leading reasons for reluctance to consider trial participation were unrelated to the pandemic but included worries about not getting the best treatment, side effects, and delaying care. Patients view trial modifications favorably, supporting continuation of these modifications, as endorsed by the National Cancer Institute and others.

RESUMEN

OBJECTIVE: HER2 mutations are associated with poor prognosis and are detected in 3-6% of cervical cancers. Neratinib, an irreversible pan-HER tyrosine kinase inhibitor, had activity in several HER2-mutant cancer types in the phase 2 SUMMIT basket study. We present updated and final results from the cervical cancer cohort of SUMMIT. METHODS: Eligible patients had HER2-mutant, metastatic or recurrent cervical cancer progressing after platinum-based treatment for advanced/recurrent disease. Patients received neratinib 240 mg/day; loperamide was mandatory during cycle 1. Confirmed objective response rate (ORR) was the primary endpoint. Duration of response (DoR), clinical benefit rate (CBR), progression-free survival (PFS), and safety were secondary endpoints. RESULTS: Twenty-two patients were enrolled; 18 (81.8%) had endocervical adenocarcinoma; median two prior systemic chemotherapy regimens (range 1-4). The most common HER2 variant was S310F/Y mutation (n = 13; 59.1%). Four patients had confirmed partial responses (ORR 18.2%; 95% CI 5.2-40.3); 6 had stable disease ≥16 weeks (CBR 45.5%; 95% CI 24.4-67.8). Median DoR was 7.6 months (95% CI 5.6-12.3). Median PFS was 5.1 months (95% CI 1.7-7.2). All-grade diarrhea (90.9%), nausea (54.5%), and constipation (54.5%) were the most common adverse events. Five patients (22.7%) reported grade 3 diarrhea. There were no grade 4 adverse events, no diarrhea-related treatment discontinuations, and two grade 5 adverse events, unrelated to neratinib: dyspnea (n = 1) and embolism (n = 1). CONCLUSIONS: Neratinib resulted in durable responses and disease control in patients with HER2-mutant metastatic/recurrent cervical cancer in SUMMIT. These findings support next-generation sequencing and tailored therapy for select patients with advanced cervical cancer. All responses occurred in patients with endocervical adenocarcinoma. Further assessment of neratinib in this setting is warranted. TRIAL REGISTRATION NUMBER: NCT01953926 (ClinicalTrials.gov), 2013-002872-42 (EudraCT).

RESUMEN

BACKGROUND: The effect of trastuzumab therapy on left atrial (LA) function remains largely unknown. Our aim was to assess the changes in LA strain parameters longitudinally in patients treated with trastuzumab. METHODS: We retrospectively studied 170 patients with stage I-IV HER2+ breast cancer. All patients had baseline echocardiograms and repeat echocardiograms at 3 months and after 1 year. We measured LA strain at all three time points. Changes in LA strain and strain rate (sr) parameters were evaluated using repeated-measures mixed-effects models. The cohort was stratified according to development of cancer therapeutics-related cardiac dysfunction (CTRCD) during follow-up. RESULTS: The mean age was 52.7 ± 13.8 years, 25.3% had hypertension and 16.0% had metastatic disease. Multiple LA strain parameters (predicted delta value, [95%CI]) showed statistically significant declines in patients who developed CTRCD from baseline to the 3-month follow-up after multivariable adjustment; LA reservoir strain (LAεres ): -4.7%; [-8.1% to -1.3%], p = .007; LA conduit strain (LAεcon ): -2.8%; [-5.3% to -.4%], p = .021); and LAεres sr: -.2/s; [-.3/s to -.09/s], p < .001). In patients who did not develop CTRCD, LA strain parameters declined significantly but to a smaller degree than in the CTRCD group (LAεres : -1.7%; [-3.1% to -.3%], p = .020, LAεcon : -2.2%; [-3.3% to -1.1%], p < .001, and LA booster pump strain : -2.4%; [-3.5% to -1.4%], p < .001). LA strain rates did not decline significantly in the non-CTRCD group. CONCLUSION: Trastuzumab treatment was associated with declines in LA strain parameters in patients with breast cancer. The largest declines were observed in patients who developed CTRCD during treatment.

RESUMEN

PURPOSE: We hypothesized that eribulin combined with cyclophosphamide (EC) would be an effective combination with tolerable toxicity for the treatment of advanced breast cancer (ABC). METHODS: Patients with histologically confirmed metastatic or unresectable ABC with any number of prior lines of therapy were eligible to enroll. In the dose escalation cohort, dose level 0 was defined as eribulin 1.1 mg/m2 and cyclophosphamide 600 mg/m2, and dose level 1 was defined as eribulin 1.4 mg/m2 and cyclophosphamide 600 mg/m2. Eribulin was given on days 1 and 8 and cyclophosphamide on day 1 of a 21-day cycle. In the dose expansion cohort, enrollment was expanded at dose level 1. The primary objective was clinical benefit rate (CBR), and secondary objectives were response rate (RR), duration of response (DOR), progression-free survival (PFS), and safety. RESULTS: No dose-limiting toxicities were identified in the dose escalation cohort (n = 6). In the dose expansion cohort, an additional 38 patients were enrolled for a total of 44 patients, including 31 patients (70.4%) with hormone receptor-positive (HR +)/HER2- disease, 12 patients (27.3%) with triple-negative breast cancer (TNBC), and 1 patient (2.3%) with HR + /HER2 + disease. Patients had a median age of 56 years (range 33-82 years), 1 prior line of hormone therapy (range 0-6), and 2 prior lines of chemotherapy (range 0-7). CBR was 79.5% (35/44; 7 partial response, 28 stable disease) and the median DOR was 16.4 weeks (range 13.8-21.1 weeks). Median PFS was 16.4 weeks (95% CI: 13.8-21.1 weeks). The most common grade 3/4 adverse event was neutropenia (47.7%, n = 21). Fourteen of 26 patients (53.8%) with circulating tumor cell (CTC) data were CTC-positive ([Formula: see text] 5 CTC/7.5 mL) at baseline. Median PFS was shorter in patients who were CTC-positive vs. negative (13.1 vs 30.6 weeks, p = 0.011). CONCLUSION: In heavily pretreated patients with ABC, treatment with EC resulted in an encouraging CBR of 79.5% and PFS of 16.4 weeks, which compares favorably to single-agent eribulin. Dose reduction and delays were primarily due to neutropenia. The contribution of cyclophosphamide to eribulin remains unclear but warrants further evaluation. NCT01554371.

RESUMEN

BACKGROUND: Comorbidities and symptoms in metastatic breast cancer patients impact treatment decisions and influence prognosis and quality of life. The objective of this study is to examine the concordance between physician documentation and patient reports of comorbidities and symptoms to understand their comparative effectiveness. METHODS: New patients with metastatic breast cancer completed an electronic intake survey assessing patient health history and symptoms. Physician documentation across 54 comorbidities and 42 symptoms was abstracted from notes for the corresponding clinic visits between November 2016 and March 2020. Concordance between patient reports and medical records for each condition and hazards ratios for each patient versus physician reported comorbidity and symptom were assessed. RESULTS: A total of 168 patients were included in the analysis (age, median = 56 years, range = 29-86 years; 131 white [78.9%]). Twenty-three of 54 comorbidities had a moderate to high level of agreement between patients and physicians (κ ≥ 0.40). Physicians documented higher numbers of comorbidities that can be objectively measured which also had higher concordance (e.g., diabetes [κ = 0.83] and hypertension [κ = 0.79]) while patients reported higher numbers of comorbidities that are more subjective which also had lower concordance (anxiety [κ = 0.30], GERD [κ = 0.36]). One physician-documented and two patient-reported comorbidities were significantly associated with survival (p < 0.05). Only 2 of 42 symptoms had a moderate to high level of agreement between patients and physicians. One physician-documented and nine patient-reported symptoms were significantly associated with decreased survival (p < 0.05). CONCLUSION: Agreement between patients' and physicians' reporting of comorbidities varies substantially, and patient reports can complement physician documentation. Physicians significantly underreported symptoms versus patients; thus, concordance was also low. Multiple patient-reported symptoms were predictive of survival; thus, incorporating them can provide more informative estimates of predicted survival.

RESUMEN

PURPOSE: Pseudocirrhosis is a term used to describe changes in hepatic contour that mimic cirrhosis radiographically, but lack the classic pathologic features of cirrhosis. This radiographic finding is frequently found in patients with metastatic breast cancer (MBC), but the risk factors and clinical consequences are poorly understood. METHODS: In this retrospective study, we identified patients with MBC and pseudocirrhosis who were treated at a single center from 2002 to 2021. We used chart extraction and radiology review to determine demographic characteristics, treatment history, imaging features, and complications of pseudocirrhosis. RESULTS: 120 patients with MBC and pseudocirrhosis were identified with the following BC subtypes: hormone receptor (HR) positive, HER2 negative (n = 99, 82.5%), HR+/HER2+ (n = 14, 11.7%), HR- /HER2+ (n = 3, 2.5%), and triple negative (TNBC; n = 4, 3.3%). All patients had liver metastases and 82.5% (n = 99) had > 15 liver lesions. Thirty-six patients (30%) presented with de novo metastatic disease. Median time from MBC diagnosis to pseudocirrhosis was 29.2 months. 50% of patients had stable or responding disease at the time of pseudocirrhosis diagnosis. Sequelae of pseudocirrhosis included radiographic ascites (n = 97, 80.8%), gastric/esophageal varices (n = 68, 56.7%), splenomegaly (n = 26, 21.7%), GI bleeding (n = 12, 10.0%), and hepatic encephalopathy (n = 11, 9.2%). Median survival was 7.9 months after pseudocirrhosis diagnosis. Radiographic ascites was associated with shorter survival compared to no radiographic ascites (42.8 vs. 76.2 months, p = < 0.001). CONCLUSIONS: This is the largest case series of patients with MBC and pseudocirrhosis. Nearly all patients had HR+ MBC and extensive liver metastases. Survival was short after pseudocirrhosis and prognosis worse with radiographic ascites.

RESUMEN

Enrollment in metastatic breast cancer trials usually requires measurable lesions, but patients with invasive lobular carcinoma (ILC) tend to form diffuse disease. We found that the proportion of patients with metastatic ILC enrolled in clinical trials at our institution was significantly lower than that of patients with invasive ductal carcinoma (IDC). Possible links between requiring measurable disease and decreased enrollment of ILC patients require further study to ensure equitable trial access.

RESUMEN

BACKGROUND: Symptom burden and reduced quality of life (QOL) are considerable hurdles in oncology. The authors used the Patient-Reported Outcomes Measurement Information System (PROMIS), which assesses physical and psychosocial health, to establish a mean symptom burden, examine potential drivers, and characterize severe symptom burden in breast cancer patient subgroups with the goal of characterizing stage IV patient QOL and triaging patients to individualized supportive care services. METHODS: New patients at the University of California San Francisco Breast Care Center received questionnaires with 8 PROMIS domains: depression, anxiety, fatigue, sleep-related impairment, sleep disturbance, cognitive function, cognitive abilities, and physical function. PROMIS values were scored with the HealthMeasures service and were compared by age, cancer stage, and educational status. RESULTS: Stage IV patients with breast cancer (n = 169) reported higher depression and fatigue and worse cognitive function, cognitive abilities, and physical function than patients with stage 0 to III disease (n = 2577). As age increased, cognitive function impairment, depression, anxiety, and sleep-related symptoms decreased. More educated patients showed better physical function and less severe sleep disturbance and fatigue. Across all subgroups, patients with high anxiety had the greatest probability of worse symptom burden and function in other domains. CONCLUSIONS: This study provides an additional set of PROMIS population estimates across breast cancer demographic groups. The analysis of a large stage IV population reinforces that metastatic patients have impaired QOL across multiple domains. Because anxiety emerged as a potential driver of impaired QOL in other domains, earlier interventions to reduce anxiety could improve QOL overall. These analyses will help to determine appropriate thresholds of intervention. LAY SUMMARY: Patients receiving treatment for breast cancer can experience decreased quality of life. This study characterized differences in self-reported quality of life among patients of different ages, with different stages of cancer, and with different educational backgrounds. This study also examined the effect of decreased quality of life in one area (eg, anxiety) on another area (eg, difficulty in sleeping). Patients who were younger, had not attended college or technical school, or had stage IV cancer tended to have worse quality of life. Patients who had high levels of anxiety also tended to have high levels of impairment in other areas.

RESUMEN

BACKGROUND: Metastatic staging imaging is not recommended for asymptomatic patients with stage I-II breast cancer. Greater distant metastatic disease risk may warrant baseline imaging in patients with stage II-III with high-risk biologic subtypes. NCCN Guidelines recommend considering CT of the chest, abdomen, and pelvis (CT CAP) and bone scan in appropriate patients. CT CAP and bone scan are considered standard of care (SoC), although PET/CT is a patient-centered alternative. METHODS: Data were available for 799 high-risk patients with clinical stage II-III disease who initiated screening for the I-SPY2 trial at 4 institutions. A total of 564 complete records were reviewed to compare PET/CT versus SoC. Costs were determined from the payer perspective using the national 2018 Medicare Physician Fee Schedule and representative reimbursements to the University of California, San Francisco (UCSF). Incremental cost-effectiveness ratio (ICER) measured cost of using PET/CT per percent of patients who avoided a false-positive (FP). RESULTS: The de novo metastatic disease rate was 4.6%. Imaging varied across the 4 institutions (P<.0001). The FP rate was higher using SoC versus PET/CT (22.1% vs 11.1%; P=.0009). Mean time between incidental finding on baseline imaging to FP determination was 10.8 days. Mean time from diagnosis to chemotherapy initiation was 44.3 days with SoC versus 37.5 days with PET/CT (P=.0001). Mean cost per patient was $1,132 (SoC) versus $1,477 (PET/CT) using the Medicare Physician Fee Schedule, with an ICER of $31. Using representative reimbursements to UCSF, mean cost per patient was $1,236 (SoC) versus $1,073 (PET/CT) for Medicare, and $3,083 (SoC) versus $1,656 (PET/CT) for a private payer, with ICERs of -$15 and -$130, respectively. CONCLUSIONS: Considerable variation exists in metastatic staging practices. PET/CT reduced FP risk by half and decreased workup of incidental findings, allowing for earlier treatment start. PET/CT may be cost-effective, and at one institution was shown to be cost-saving. Better alignment is needed between hospital pricing strategies and payer coverage policies to deliver high-value care.

RESUMEN

Responses to immunotherapy are uncommon in estrogen receptor (ER)-positive breast cancer and to date, lack predictive markers. This randomized phase II study defines safety and response rate of epigenetic priming in ER-positive breast cancer patients treated with checkpoint inhibitors as primary endpoints. Secondary and exploratory endpoints included PD-L1 modulation and T-cell immune-signatures. 34 patients received vorinostat, tamoxifen and pembrolizumab with no excessive toxicity after progression on a median of five prior metastatic regimens. Objective response was 4% and clinical benefit rate (CR + PR + SD > 6 m) was 19%. T-cell exhaustion (CD8+ PD-1+/CTLA-4+) and treatment-induced depletion of regulatory T-cells (CD4+ Foxp3+/CTLA-4+) was seen in tumor or blood in 5/5 patients with clinical benefit, but only in one non-responder. Tumor lymphocyte infiltration was 0.17%. Only two non-responders had PD-L1 expression >1%. This data defines a novel immune signature in PD-L1-negative ER-positive breast cancer patients who are more likely to benefit from immune-checkpoint and histone deacetylase inhibition (NCT02395627).

RESUMEN

PURPOSE: The phosphatidylinositol 3-kinase/Akt/mammalian target of rapamycin is a key pathway of survival and therapeutic resistance in breast cancer. We evaluated the pan-Akt inhibitor MK-2206 in combination with standard therapy in patients with high-risk early-stage breast cancer. PATIENTS AND METHODS: I-SPY 2 is a multicenter, phase II, open-label, adaptively randomized neoadjuvant platform trial that screens experimental therapies and efficiently identifies potential predictive biomarker signatures. Patients are categorized by human epidermal growth factor receptor 2 (HER2), hormone receptor (HR), and MammaPrint statuses in a 2 × 2 × 2 layout. Patients within each of these 8 biomarker subtypes are adaptively randomly assigned to one of several experimental therapies, including MK-2206, or control. Therapies are evaluated for 10 biomarker signatures, each of which is a combination of these subtypes. The primary end point is pathologic complete response (pCR). A therapy graduates with one or more of these signatures if and when it has an 85% Bayesian predictive probability of success in a hypothetical phase III trial, adjusting for biomarker covariates. Patients in the current report received standard taxane- and anthracycline-based neoadjuvant therapy without (control) or with oral MK-2206 135 mg/week. RESULTS: MK-2206 graduated with 94 patients and 57 concurrently randomly assigned controls in 3 graduation signatures: HR-negative/HER2-positive, HR-negative, and HER2-positive. Respective Bayesian mean covariate-adjusted pCR rates and percentage probability that MK-2206 is superior to control were 0.48:0.29 (97%), 0.62:0.36 (99%), and 0.46:0.26 (94%). In exploratory analyses, MK-2206 evinced a numerical improvement in event-free survival in its graduating signatures. The most significant grade 3-4 toxicity was rash (14% maculopapular, 8.6% acneiform). CONCLUSION: The Akt inhibitor MK-2206 combined with standard neoadjuvant therapy resulted in higher estimated pCR rates in HR-negative and HER2-positive breast cancer. Although MK-2206 is not being further developed at this time, this class of agents remains of clinical interest.

RESUMEN

PURPOSE: This pilot study was performed to test our ability to administer neratinib monotherapy before clinically recommended craniotomy in patients with HER2-positive metastatic breast cancer to the central nervous system, to examine neratinib's central nervous system penetration at craniotomy, and to examine postoperative neratinib maintenance. PATIENTS AND METHODS: Patients with HER2-positive brain metastases undergoing clinically indicated cranial resection of a parenchymal tumor received neratinib 240 mg orally once a day for 7 to 21 days preoperatively, and resumed therapy postoperatively in 28-day cycles. Exploratory evaluations of time to disease progression, survival, and correlative tissue, cerebrospinal fluid (CSF), and blood-based analyses examining neratinib concentrations were planned. The study was registered at ClinicalTrials.gov under number NCT01494662. RESULTS: We enrolled 5 patients between May 22, 2013, and October 18, 2016. As of March 1, 2019, patients had remained on the study protocol for 1 to 75+ postoperative cycles pf therapy. Two patients had grade 3 diarrhea. Evaluation of the CSF showed low concentrations of neratinib; nonetheless, 2 patients continued to receive therapy without disease progression for at least 13 cycles, with one on-study treatment lasting for nearly 6 years. Neratinib distribution in surgical tissue was variable for 1 patient, while specimens from 2 others did not produce conclusive results as a result of limited available samples. CONCLUSION: Neratinib resulted in expected rates of diarrhea in this small cohort, with 2 of 5 patients receiving the study treatment for durable periods. Although logistically challenging, we were able to test a limited number of CSF- and parenchymal-based neratinib concentrations. Our findings from resected tumor tissue in one patient revealed heterogeneity in drug distribution and tumor histopathology.

BACKGROUND: Many patients' activity levels decrease during chemotherapy. Wearable devices, such as Fitbits, track activity patterns and may encourage behavior change. This study aimed to determine the utility of using Fitbits to measure physical activity and sleep throughout chemotherapy. PATIENTS AND METHODS: Patients with early stage breast cancer were enrolled prior to starting chemotherapy. Patients received a Fitbit Charge HR and were instructed to wear it and sync at least weekly throughout chemotherapy and up to 6 months post therapy. Patients completed baseline surveys, and treatment information was collected from their medical records. Fitbit data was downloaded from the Fitabase data management platform. To assess utility, we evaluated how many days patients wore their Fitbit for at least 10 hours. RESULTS: Adherence to wearing the Fitbit was low, with 16.9% of patients never syncing their device. For those who did sync, the mean number of valid days (> 10 hours of use) across the 9-month study period was 44.5% (SD, 36.9%), and the median was 39.6%, with a range of 0% to 100% of the total study days. Adherence was higher among participants receiving adjuvant chemotherapy versus neoadjuvant chemotherapy (51.9% vs. 29.6% valid days, respectively [P = .037]). Baseline questions indicating positive attitudes toward technology were significantly correlated with higher adherence. CONCLUSIONS: Fitbit use during breast cancer chemotherapy was poor in the absence of prompts to encourage wear. Interventions including phone calls, texts, or other reminders to maintain adherence are likely necessary to increase wear in active treatment settings.

RESUMEN

PURPOSE: Breast cancer patients with progressing central nervous system (CNS) disease have limited treatment options. Few chemotherapy drugs with activity in breast cancer have well-documented CNS penetration. This phase 2 trial evaluated efficacy and safety of irinotecan 125 mg/m2 on days 1 and 15 with temozolomide 100 mg/m2 days 1-7 and days 15-21 of a 28 day cycle. METHODS: Breast cancer patients of any biological subtype and progressing brain metastases and/or leptomeningeal disease (LMD) were eligible. The primary endpoint was CNS response rate. Secondary endpoints were clinical benefit rate (CBR), time to progression (TTP), and overall survival (OS). Imaging studies evaluating intracranial and extracranial response were performed every 8 weeks. RESULTS: Thirty patients were evaluable for safety and efficacy. The most common hematologic and non-hematologic adverse events were neutropenia, and nausea and fatigue, respectively. There were two confirmed CNS partial responses (PR) and five patients with stable disease in the CNS ≥ 16 weeks, resulting in a 7% PR and 23% CBR. Median TTP was 2.3 months (range 13-444 days), and median OS from treatment initiation until death was 4.9 months (range 20-1023 days). Excluding patients with LMD, median TTP and OS were 3.1 and 5.6 months, respectively. Only one patient progressed systemically before CNS progression. CONCLUSIONS: The combination of irinotecan and temozolomide was well tolerated, demonstrated some clinical activity across multiple breast cancer subtypes with progressing CNS disease, and offers a reasonable option for patients who are not candidates for further radiation or clinical trials.

RESUMEN

PURPOSE: Evidence-based treatments for metastatic, human epidermal growth factor receptor 2 (HER2)-positive breast cancer to the CNS are limited. We previously reported modest activity of neratinib monotherapy for HER2-positive breast cancer brain metastases. Here we report the results from additional study cohorts. PATIENTS AND METHODS: Patients with measurable, progressive, HER2-positive brain metastases (92% after receiving CNS surgery and/or radiotherapy) received neratinib 240 mg orally once per day plus capecitabine 750 mg/m2 twice per day for 14 days, then 7 days off. Lapatinib-naïve (cohort 3A) and lapatinib-treated (cohort 3B) patients were enrolled. If nine or more of 35 (cohort 3A) or three or more of 25 (cohort 3B) had CNS objective response rates (ORR), the drug combination would be deemed promising. The primary end point was composite CNS ORR in each cohort separately, requiring a reduction of 50% or more in the sum of target CNS lesion volumes without progression of nontarget lesions, new lesions, escalating steroids, progressive neurologic signs or symptoms, or non-CNS progression. RESULTS: Forty-nine patients enrolled in cohorts 3A (n = 37) and 3B (n = 12; cohort closed for slow accrual). In cohort 3A, the composite CNS ORR = 49% (95% CI, 32% to 66%), and the CNS ORR in cohort 3B = 33% (95% CI, 10% to 65%). Median progression-free survival was 5.5 and 3.1 months in cohorts 3A and 3B, respectively; median survival was 13.3 and 15.1 months. Diarrhea was the most common grade 3 toxicity (29% in cohorts 3A and 3B).Neratinib plus capecitabine is active against refractory, HER2-positive breast cancer brain metastases, adding additional evidence that the efficacy of HER2-directed therapy in the brain is enhanced by chemotherapy. For optimal tolerance, efforts to minimize diarrhea are warranted.

RESUMEN

Chemotherapy-induced alopecia remains an emotionally traumatic side effect for cancer patients that impacts the quality of life, may be protracted in duration and may influence treatment decisions. Scalp cooling has been shown to be effective in preventing chemotherapy-induced alopecia. The DigniCap Scalp Cooling System is designed to prevent hair loss by cooling the scalp to reduce the impact of chemotherapy on hair follicle cells. Recent studies have shown the safety, efficacy and low-grade toxicity of the DigniCap System with a 66.3% success rate in hair preservation (n = 106) relative to 0% in a nonrandomized control group according to a prospective pivotal study. Data also support improved quality of life in several domains. Two scalp cooling devices including the DigniCap are now US FDA cleared and can be offered as a part of standard of care.

RESUMEN

PURPOSE: This study evaluated the use of an electronic Health Questionnaire System (HQS) within the University of California San Francisco Breast Care Center as a screening and triage tool to proactively recognize patients' supportive care needs during new patient consultations and identify demographic characteristics associated with referrals to three supportive care services. PATIENTS AND METHODS: A total of 428 patients with and without breast cancer between the ages of 18 and 84 years completed HQS intake forms before appointments at the University of California San Francisco Breast Care Center between November 2014 and May 2015 and agreed to participate in this study. Patient HQS responses triggered referrals to supportive care services, and a review of electronic health records was conducted to determine the outcomes of these referrals. RESULTS: A total of 242 patients (56.5%) met criteria for at least one supportive care referral. Women with invasive breast cancer or ductal carcinoma in situ met criteria for supportive services more frequently than women without breast cancer diagnoses (76.9% v 23.8%; P < .001) and were most likely to receive referrals for genetic counseling (67.0%), psychological services (32.2%), and social services (12.1%). Multivariable logistic regression analysis showed that being married was associated with fewer referrals to social work (OR, 0.42; 95% CI, 0.21 to 0.81) and that those between 45 and 54 years of age were less likely to receive referrals to genetic counseling than those ≥ 55 years of age (OR, 0.41; 95% CI, 0.23 to 0.73). Among all referrals (n = 369), 26.8% resulted in completed appointments. CONCLUSION: Using an automated intake form is an efficient way to identify and triage individuals in need of supportive care services and can provide insight into the populations with supportive care needs for targeted outreach.
