Evaluating Patient Experience in a Multidisciplinary Breast Cancer Clinic: A Prospective Study.

Background: Multidisciplinary clinics (MDCs) are a care model in which patients see several physicians across specialties and/or other allied health professionals in a single appointment in a shared space. This study sought to better understand patients' experiences with breast cancer (BC) MDC. Methods: A total of 429 patients diagnosed with BC and seen in a MDC between November 2020 and November 2021 were invited to participate in a patient experience survey. Results: In total, 116 patient respondents (27%) with representative demographics described their experience. Most patients report feeling "somewhat prepared" for the BC MDC experience (67%, median = 3.7, interquartile range [IQR] = 1.9), but with variability. The major areas of positive feedback were that the MDC was convenient (89.3%), efficient use of time (65.2%), and a good way to get questions answered (65.2%). Major criticisms included that the MDC was overwhelming (16.1%) and/or too long (4.5%). When asked to rate the top three satisfaction areas of MDCs, patients chose seeing multiple providers during a single visit (80.4%), communication about the process before and throughout the MDC (48.2%), and inclusivity of their support system (38.4%). The highest rated dissatisfiers were the volume of information presented (42.9%) and patients' emotional comfort (anxiety/stress) during MDC appointment (30.2%). Overall, 83% of patients with BC rate the MDC experience as excellent (median = 4.8, IQR = 0.9) and would be "very likely" to recommend BC MDC (median = 4.8, IQR = 0.9). Conclusion: Patients value seeing multiple providers simultaneously in an environment inclusive of their support systems, which is described as convenient and efficient. Improving emotional distress is a key opportunity to improve patient experience.

Frequent pathologic complete responses in aggressive stages II to III breast cancers with every-4-week carboplatin and weekly paclitaxel with or without trastuzumab: a Brown University Oncology Group Study.

PURPOSE: To evaluate the efficacy and safety of neoadjuvant carboplatin and weekly paclitaxel +/- weekly trastuzumab in resectable and locally advanced breast cancer. PATIENTS AND METHODS: Women with stages IIA to IIIB disease received carboplatin dosed by six times the area under the curve every 4 weeks and paclitaxel 80 mg/m(2) weekly for 16 weeks, and weekly trastuzumab was added for human epidermal growth factor receptor 2 (HER2) -positive status. The primary end point was the pathologic complete response (pCR) rate, defined as the absence of invasive disease in the breast and axillary nodes. Postoperative therapies were at the discretion of the treating physicians. RESULTS: Fifty-five patients were enrolled, and of these 43 had resectable disease. The median age was 54 years (range, 31 to 74 years). Treatment was well tolerated; there were no episodes of febrile neutropenia or grade 4 thrombocytopenia, and there were only two instances of grade 3 peripheral neuropathy. Overall, the pCR rate was 45%. The pCR rate was 43% (95% CI, 28% to 58%) in patients with resectable disease. Higher pCR rates occurred in patients with HER2-positive tumors (76% v 31% for HER2-negative tumors; P = .003), with estrogen receptor (ER) -negative tumors (75% v 27% for ER-positive tumors; P = .001), or with triple-negative tumors (67% v 12% ER-positive and HER2-negative tumors; P = .002). At a median of 28 months postoperation, recurrence-free survival (RFS) was 88.7%. If patients with ER-positive and HER2-negative tumors are excluded from analysis, patients who achieved a pCR were less likely to experience disease recurrence (RFS, 86%) than those who did not achieve a pCR (RFS, 75%). CONCLUSION: Neoadjuvant carboplatin and weekly paclitaxel +/- trastuzumab achieve high pCR rates in patients with HER2-positive and triple-negative disease without exposure to an anthracycline. Preliminary RFS results are encouraging but are likely influenced by adjuvant therapy received. Additional study of this regimen in high-risk patients is warranted.

Clinical characteristics of women presenting with skin-only recurrence of breast cancer.

BACKGROUND: Locoregional failure after breast cancer treatment is usually heralded as a significant risk factor for systemic recurrence. However, locoregional recurrence may have different presentations, some of which may represent a more benign course. An example of this is the phenomenon of isolated chest wall recurrence (CWR). Given the paucity of data describing the clinical outcomes of women who recur this way, we sought to review the natural history and prognosis of patients presenting with this specific presentation. METHODS: Women who previously underwent primary treatment for breast cancer and subsequently developed an isolated CWR were identified. Histologic and treatment data as it related to their primary diagnosis and demographic data were obtained by chart review. Modalities of treatment for isolated CWR were also collected. RESULTS: We identified 17 patients who experienced an isolated CWR from January 1987 to May 2005. The median age at original diagnosis was 61 years (range 33-94 years). Median time to isolated CWR was 20 months (range 6-134). Eleven patients were treated with primary resection, 12 with radiotherapy, and 3 with a combination of hyperthermia and electron beam radiation. Ten patients went on to receive endocrine therapy, 6 received chemotherapy, and 2 were observed. Ten of these patients (58%) experienced a second event and for this group the median time to second event was 24 months (range 8-109). Median overall survival was 80 months (range 3-134) for the entire cohort. CONCLUSIONS: Patients experiencing a chest wall recurrence may have a benign course suggesting this may be an indolent presentation of local regional recurrence. The proper therapy of these patients may require further study.

Trastuzumab and vinorelbine as first-line therapy for HER2-overexpressing metastatic breast cancer: multicenter phase II trial with clinical outcomes, analysis of serum tumor markers as predictive factors, and cardiac surveillance algorithm.

PURPOSE: Trastuzumab-based therapy improves survival for women with human epidermal growth factor receptor 2 (HER2)-positive advanced breast cancer. We conducted a multicenter phase II study to evaluate the efficacy and safety of trastuzumab combined with vinorelbine, and to assess cardiac surveillance algorithms and tumor markers as prognostic tools. PATIENTS AND METHODS: Patients with HER2-positive (immunohistochemistry [IHC] 3+-positive or fluorescence in situ hybridization [FISH]-positive) metastatic breast cancer received first-line chemotherapy with trastuzumab and vinorelbine to determine response rate. Eligibility criteria were measurable disease and baseline ejection fraction >or= 50%. Serial testing for HER2 extracellular domain (ECD) was performed. RESULTS: Fifty-four women from 17 participating centers were entered onto the study. The overall response rate was 68% (95% confidence interval, 54% to 80%). Response rates were not affected by method of HER2 status determination (FISH v IHC) or by prior adjuvant chemotherapy. Median time to treatment failure was 5.6 months; 38% of patients were progression free after 1 year. Concurrent therapy was quite feasible with maintained dose-intensity. Patients received both chemotherapy and trastuzumab on 90% of scheduled treatment dates. Two patients experienced cardiotoxicity in excess of grade 1; one patient experienced symptomatic heart failure. A surveillance algorithm of screening left ventricular ejection fraction (LVEF) at 16 weeks successfully identified women at risk for experiencing cardiotoxicity. Other acute and chronic side effects were tolerable. Lack of decline in HER2 ECD during cycle 1 predicted tumor progression. CONCLUSION: Trastuzumab and vinorelbine constitute effective and well-tolerated first-line treatment for HER2-positive metastatic breast cancer. Patients with normal LVEF can be observed with surveillance of LVEF at 16 weeks to identify those at risk for cardiotoxicity.

Adjuvant therapy in breast cancer.

The new millennium ushers in an exciting time in the treatment of early stage breast cancer. Although worldwide incidence statistics have not changed significantly in the past decade, mortality rates have declined. This change seems to be related to public health initiatives that increase early detection and awareness and to an increase in the efficacy of adjuvant treatments, including advances in chemotherapy and the emergence of biologic treatments. Physicians from many specialties participate in multidisciplinary tumor boards. Moreover, patients, families, and advocacy groups have taken on new responsibilities, offering encouragement and support for clinical and basic research.
