RESUMEN

BACKGROUND: The current randomized trial examined the effects of a Tibetan yoga program (TYP) versus a stretching program (STP) and usual care (UC) on sleep and fatigue in women with breast cancer who were undergoing chemotherapy. METHODS: Women with stage (American Joint Committee on Cancer (AJCC) TNM) I to III breast cancer who were undergoing chemotherapy were randomized to TYP (74 women), STP (68 women), or UC (85 women). Participants in the TYP and STP groups participated in 4 sessions during chemotherapy, followed by 3 booster sessions over the subsequent 6 months, and were encouraged to practice at home. Self-report measures of sleep disturbances (Pittsburgh Sleep Quality Index), fatigue (Brief Fatigue Inventory), and actigraphy were collected at baseline; 1 week after treatment; and at 3, 6, and 12 months. RESULTS: There were no group differences noted in total sleep disturbances or fatigue levels over time. However, patients in the TYP group reported fewer daily disturbances 1 week after treatment compared with those in the STP (difference, -0.43; 95% confidence interval [95% CI], -0.82 to -0.04 [P = .03]) and UC (difference, -0.41; 95% CI, -0.77 to -0.05 [P = .02]) groups. Group differences at the other time points were maintained for TYP versus STP. Actigraphy data revealed greater minutes awake after sleep onset for patients in the STP group 1 week after treatment versus those in the TYP (difference, 15.36; 95% CI, 7.25-23.48 [P = .0003]) and UC (difference, 14.48; 95% CI, 7.09-21.87 [P = .0002]) groups. Patients in the TYP group who practiced at least 2 times a week during follow-up reported better Pittsburgh Sleep Quality Index and actigraphy outcomes at 3 months and 6 months after treatment compared with those who did not and better outcomes compared with those in the UC group. CONCLUSIONS: Participating in TYP during chemotherapy resulted in modest short-term benefits in sleep quality, with long-term benefits emerging over time for those who practiced TYP at least 2 times a week.

RESUMEN

BACKGROUND: The National Comprehensive Cancer Network (NCCN) and the American Society of Clinical Oncology (ASCO) provide guidelines regarding axillary nodal evaluation in ductal carcinoma in situ (DCIS), but data regarding national compliance with these guidelines remains incomplete. METHODS: We conducted a retrospective review of the National Cancer Data Base (NCDB) analyzing all surgical approaches to axillary evaluation in patients with DCIS. Logistic regression analysis was used to assess the multivariate relationship between patient demographics, clinical characteristics, and probability of axillary evaluation. RESULTS: We identified 88,083 patients diagnosed with DCIS between 1998 and 2011; 31,912 (37%) underwent total mastectomy (TM) and 55,349 (63%) had breast conserving therapy (BCT). Axillary evaluation increased from 44.4% in 1998 to 63.3% in 2011. In TM patients, axillary evaluation increased from 74.3% in 1998 to 93.4% in 2011. This correlated with an increase in sentinel lymph node biopsy (SLNB) from 24.3 to 77.1%, while ALND decreased from 50.0 to 16.3% (p <0.01). In BCT patients, evaluation increased from 20.1 to 43.9%; SLNB increased from 7.2 to 39.4% and ALND decreased from 12.9 to 4.5%. Factors associated with axillary nodal evaluation in BCT patients included practice type and facility location. Among TM patients, use of axillary lymph node dissection (ALND) for axillary staging was associated with earlier year of diagnosis, black race, and older age, as well as community practice setting and practice location in the Southern US. CONCLUSIONS: Compliance with national guidelines regarding axillary evaluation in DCIS remains varied. Practice type and location-based differences suggest opportunities for education regarding the appropriate use of axillary nodal evaluation in patients with DCIS.

RESUMEN

BACKGROUND: Although epidemiological research demonstrates that there is an association between lifestyle factors and risk of breast cancer recurrence, progression of disease, and mortality, no comprehensive lifestyle change clinical trials have been conducted to determine if changing multiple risk factors leads to changes in biobehavioral processes and clinical outcomes in women with breast cancer. This article describes the design, feasibility, adherence to the intervention and data collection, and patient experience of a comprehensive lifestyle change clinical trial (CompLife). METHODS: CompLife is a randomized, controlled trial of a multiple-behavior intervention focusing on diet, exercise, and mind-body practice along with behavioral counseling to support change. The initial exposure to the intervention takes place during the 4 to 6 weeks of radiotherapy (XRT) for women with stage III breast cancer and then across the subsequent 12 months. The intervention group will have 42 hours of in-person lifestyle counseling during XRT (7-10 hours a week) followed by up to 30 hours of counseling via video connection for the subsequent 12 months (weekly sessions for 6 months and then monthly for 6 months). The primary outcome is disease-free survival. Multiple secondary outcomes are being evaluated, including: (1) biological pathways; (2) overall survival; (3) patient-reported outcomes; (4) dietary patterns/fitness levels, anthropometrics, and body composition; and (5) economic outcomes. Qualitative data of the patient experience in the trial is collected from exit interviews, concluding remarks, direct email correspondences, and web postings from patients. RESULTS: Fifty-five patients have been recruited and randomized to the trial to date. Accrual of eligible patients is high (72%) and dropout rates extremely low (5%). Attendance to the in-person sessions is high (95% attending greater than 80% of sessions) as well as to the 30 hours of video counseling (88% attending more than 70% of sessions). Adherence to components of the behavior change intervention is high and compliance with the intensive amount of data collection is exceptional. Qualitative data collected from the participants reveals testimonials supporting the importance of the comprehensive nature of intervention, especially the mind-body/mindfulness component and social support, and meaningful lifestyle transformations. CONCLUSION: Conducting a comprehensive, multicomponent, lifestyle change clinical trial for women with breast was feasible and collection of biobehavioral outcomes successful. Adherence to behavior change was high and patient experience was overwhelmingly positive.

RESUMEN

PURPOSE: Placing clips in nodes with biopsy-confirmed metastasis before initiating neoadjuvant therapy allows for evaluation of response in breast cancer. Our goal was to determine if pathologic changes in clipped nodes reflect the status of the nodal basin and if targeted axillary dissection (TAD), which includes sentinel lymph node dissection (SLND) and selective localization and removal of clipped nodes, improves the false-negative rate (FNR) compared with SLND alone. METHODS: A prospective study of patients with biopsy-confirmed nodal metastases with a clip placed in the sampled node was performed. After neoadjuvant therapy, patients underwent axillary surgery and the pathology of the clipped node was compared with other nodes. Patients undergoing TAD had SLND and selective removal of the clipped node using iodine-125 seed localization. The FNR was determined in patients undergoing complete axillary lymphadenectomy (ALND). RESULTS: Of 208 patients enrolled in this study, 191 underwent ALND, with residual disease identified in 120 (63%). The clipped node revealed metastases in 115 patients, resulting in an FNR of 4.2% (95% CI, 1.4 to 9.5) for the clipped node. In patients undergoing SLND and ALND (n = 118), the FNR was 10.1% (95% CI, 4.2 to 19.8), which included seven false-negative events in 69 patients with residual disease. Adding evaluation of the clipped node reduced the FNR to 1.4% (95% CI, 0.03 to 7.3; P = .03). The clipped node was not retrieved as an SLN in 23% (31 of 134) of patients, including six with negative SLNs but metastasis in the clipped node. TAD followed by ALND was performed in 85 patients, with an FNR of 2.0% (1 of 50; 95% CI, 0.05 to 10.7). CONCLUSION: Marking nodes with biopsy-confirmed metastatic disease allows for selective removal and improves pathologic evaluation for residual nodal disease after chemotherapy.

RESUMEN

BACKGROUND: The risk of developing breast cancer rises with increasing age. The very elderly population (80 years of age and greater) is often excluded from both clinical trials and retrospective analyses. We performed a retrospective review of the very elderly population treated at our institution in order to assess treatment patterns and the safety of therapy in an older population. DATA SOURCES: In this institutional experience at a comprehensive cancer center, we retrospectively reviewed the charts of patients 80 years and older diagnosed with a new breast cancer between September 1, 1989, and September 1, 2004. RESULTS: Two hundred thirteen patients were identified for this study. Median age was 83 (range 80-97). Median survival was 7.28 years, with a median follow up of 4 years for patients still alive at the end of the study period. Ninety-eight percent of patients (208/213) received 1 or more components of recommended multimodality treatment. Five patients refused all treatment. Overall, complications affected 12% of patients who received treatment (26/208). There were 2 deaths, 1 after surgery and 1 related to chemotherapy. The majority, 69% (18/26), of the documented complications were classified as minor. Surgery resulted in complications in 6% (11/188) of patients. Five percent (5/112) of patients who received radiation suffered adverse effects. Chemotherapy-related complications affected 30% (6/18) of treated patients. Hormonal agents resulted in complications in 3% (3/112) of patients. No correlation between the American Society of Anesthesiologists score and incidence of complication was observed (P = .58). CONCLUSIONS: Very elderly patients can be safely treated with surgery and radiation in accordance with accepted recommendations for their stage of breast cancer. Treatment with surgery and/or radiation should be considered despite age and moderate comorbidity in order to affect locoregional control. Chemotherapy results in a significant incidence of complications and should be cautiously implemented in this age group. A prospective trial is necessary to assess the necessity of aggressive multimodality therapy in this very elderly population.

RESUMEN

OBJECTIVE: To assess the accuracy of physical examination, ultrasonography, and mammography in predicting residual size of breast tumors following neoadjuvant chemotherapy. BACKGROUND: Neoadjuvant chemotherapy is an accepted part of the management of stage II and III breast cancer. Accurate prediction of residual pathologic tumor size after neoadjuvant chemotherapy is critical in guiding surgical therapy. Although physical examination, ultrasonography, and mammography have all been used to predict residual tumor size, there have been conflicting reports about the accuracy of these methods in the neoadjuvant setting. METHODS: We reviewed the records of 189 patients who participated in 1 of 2 protocols using doxorubicin-containing neoadjuvant chemotherapy, and who had assessment by physical examination, ultrasonography, and/or mammography no more than 60 days before their surgical resection. Size correlations were performed using Spearman rho analysis. Clinical and pathologic measurements were also compared categorically using the weighted kappa statistic. RESULTS: Size estimates by physical examination, ultrasonography, and mammography were only moderately correlated with residual pathologic tumor size after neoadjuvant chemotherapy (correlation coefficients: 0.42, 0.42, and 0.41, respectively), with an accuracy of +/-1 cm in 66% of patients by physical examination, 75% by ultrasonography, and 70% by mammography. Kappa values (0.24-0.35) indicated poor agreement between clinical and pathologic measurements. CONCLUSION: Physical examination, ultrasonography, and mammography were only moderately useful for predicting residual pathologic tumor size after neoadjuvant chemotherapy.

RESUMEN

BACKGROUND: To date, the impact of the National Surgical Adjuvant Breast and Bowel Project (NSABP) B-24 trial reported in 1999 on the use of tamoxifen after surgery for ductal carcinoma in situ (DCIS) is unknown. The current study was designed to evaluate the impact of NSABP B-24 on current practices at a comprehensive cancer center. METHODS: The records of 350 consecutive patients with DCIS who were treated at the authors' institution between July 1999 and June 2002 were obtained from a prospective database and analyzed. Whether patients were offered tamoxifen, whether patients accepted tamoxifen, and the associated reasons were recorded along with tamoxifen-related side effects and patient compliance with therapy. Clinical and pathologic factors were evaluated for their impact on recommendations regarding tamoxifen. Differences were assessed by chi-square analysis. RESULTS: Of the 350 patients, 73 were excluded because of evidence of invasive carcinoma on final pathology review. Of the remaining 277 patients, 166 patients (60%) were offered tamoxifen, and 90 patients (54%) chose to take tamoxifen. Of 111 patients who were not offered tamoxifen, 39 patients (35%) had documented explanations, which included bilateral mastectomy (n = 25 patients), medical reasons (n = 10 patients), and already received tamoxifen for other reasons at the time of diagnosis (n = 4 patients). Of 94 patients who received tamoxifen, 20 patients (21%) discontinued use because of side effects or complications. Tamoxifen was more likely to be recommended for women who underwent segmental resection compared with women who underwent total mastectomy (P = 0.002) and for women with smaller pathologic DCIS tumors (P = 0.001). In addition, these two factors were interrelated. CONCLUSIONS: Physicians and patients remain cautious regarding the use of tamoxifen after local treatment for DCIS. The current findings have implications for current trials evaluating aromatase inhibitors and other chemopreventive agents for this disease.
