    Purpose: We evaluated the prognostic and predictive value of circulating tumor cells (CTCs) hormone receptor–positive (HRþ) metastatic breast cancer (MBC) patients randomized to letrozole alone or letrozole plus bevacizumab in the first-line setting (CALGB 40503). Experimental Design: Blood samples were collected at pretreatment and three additional time points during therapy. The presence of ≥5 CTCs per 7.5 mL of blood was considered CTC positive. Association of CTCs with progression-free survival (PFS) and overall survival (OS) was assessed using Cox regression models. Results: Of 343 patients treated, 294 had CTC data and were included in this analysis. Median follow-up was 39 months. In multivariable analysis, CTC-positive patients at baseline (31%) had significantly reduced PFS [HR, 1.49; 95% confidence interval (CI), 1.12–1.97] and OS (HR, 2.08; 95% CI, 1.49–2.93) compared with CTC negative. Failure to clear CTCs during treatment was associated with significantly increased risk of progression (HR, 2.2; 95% CI, 1.58–3.07) and death (HR, 3.4; 95% CI, 2.36–4.88). CTC-positive patients who received only letrozole had the worse PFS (HR, 2.3; 95% CI, 1.54–3.47) and OS (HR, 2.6; 95% CI, 1.59–4.40). Median PFS in CTC-positive patients was significantly longer (18.0 vs. 7.0 months) in letrozole plus bevacizumab versus letrozole arm (P ¼ 0.0009). Restricted mean survival time analysis further revealed that addition of bevacizumab was associated with PFS benefit in both CTC-positive and CTC-negative patients, but OS benefit was only observed in CTC-positive patients. Conclusions: CTCs were highly prognostic for the addition of bevacizumab to first-line letrozole in patients with HRþ MBC in CALGB 40503. Further research to determine the potential predictive value of CTCs in this setting is warranted

    Purpose: Women with HER2-positive breast cancer treated prior to effective anti-HER2 therapy have higher rates of local–regional recurrence (LRR) than those with HER2-negative disease. Effective systemic therapy, however, has been shown to decrease LRR. This study examines LRR in women with HER2-positive breast cancer treated on a single-arm prospective multicenter trial of adjuvant trastuzumab (H) and paclitaxel (T). Methods: Patients with HER2-positive tumors ≤ 3.0 cm with negative axillary nodes or micrometastatic disease were eligible. Systemic therapy included weekly T and H for 12 weeks followed by continuation of H to complete 1 year. Radiation therapy (RT) was required following breast-conserving surgery (BCS), but dose and fields were not specified. Disease-free survival (DFS) and LRR-free survival were calculated using the Kaplan–Meier method. Results: Of the 410 patients enrolled from September 2007 to September 2010, 406 initiated protocol therapy and formed the basis of this analysis. A total of 272 (67%) had hormone receptor-positive tumors. Of 162 patients undergoing mastectomy, local therapy records were unavailable for two. None of the 160 for whom records were available received RT. Among 244 BCS patients, detailed RT records were available for 217 (89%). With a median follow-up of 6.5 years, 7-year DFS was 93.3% (95% CI 90.4–96.2), and LRR-free survival was 98.6% (95% CI 97.4–99.8). Conclusion: LRR in this select group of early-stage patients with HER2-positive disease receiving effective anti-HER2 therapy is extremely low. If confirmed in additional studies, future investigational efforts should focus on de-escalating local therapy

    PURPOSE The Adjuvant Paclitaxel and Trastuzumab trial was designed to address treatment of patients with small human epidermal growth factor receptor 2 (HER2)–positive breast cancer. The primary analysis of the Adjuvant Paclitaxel and Trastuzumab trial demonstrated a 3-year disease-free survival (DFS) of 98.7%. In this planned secondary analysis, we report longer-term outcomes and exploratory results to characterize the biology of small HER2-positive tumors and genetic factors that may predispose to paclitaxel-induced peripheral neuropathy (TIPN). PATIENTS AND METHODS In this phase II study, patients with HER2-positive breast cancer with tumors 3 cm or smaller and negative nodes received paclitaxel (80 mg/m2) with trastuzumab for 12 weeks, followed by trastuzumab for 9 months. The primary end point was DFS. Recurrence-free interval (RFI), breast cancer–specific survival, and overall survival (OS) were also analyzed. In an exploratory analysis, intrinsic subtyping by PAM50 (Prosigna) and calculation of the risk of recurrence score were performed on the nCounter analysis system on archival tissue. Genotyping was performed to investigate TIPN. RESULTS A total of 410 patients were enrolled from October 2007 to September 2010. After a median follow-up of 6.5 years, there were 23 DFS events. The 7-year DFS was 93% (95% CI, 90.4 to 96.2) with four (1.0%) distant recurrences, 7-year OS was 95% (95% CI, 92.4 to 97.7), and 7-year RFI was 97.5% (95% CI, 95.9 to 99.1). PAM50 analyses (n = 278) showed that most tumors were HER2-enriched (66%), followed by luminal B (14%), luminal A (13%), and basal-like (8%). Genotyping (n = 230) identified one single-nucleotide polymorphism, rs3012437, associated with an increased risk of TIPN in patients with grade 2 or greater TIPN (10.4%). CONCLUSION With longer follow-up, adjuvant paclitaxel and trastuzumab is associated with excellent long-term outcomes. Distribution of PAM50 intrinsic subtypes in small HER2-positive tumors is similar to that previously reported for larger tumors

    PURPOSE Older women with breast cancer remain under-represented in clinical trials. The Cancer and Leukemia Group B 49907 trial focused on women age 65 years and older. We previously reported the primary analysis after a median follow-up of 2.4 years. Standard adjuvant chemotherapy showed significant improvements in recurrence-free survival (RFS) and overall survival compared with capecitabine. We now update results at a median follow-up of 11.4 years. PATIENTS AND METHODS Patients age 65 years or older with early breast cancer were randomly assigned to either standard adjuvant chemotherapy (physician's choice of either cyclophosphamide, methotrexate, and fluorouracil or cyclophosphamide and doxorubicin) or capecitabine. An adaptive Bayesian design was used to determine sample size and test noninferiority of capecitabine. The primary end point was RFS. RESULTS The design stopped accrual with 633 patients at its first sample size assessment. RFS remains significantly longer for patients treated with standard chemotherapy. At 10 years, in patients treated with standard chemotherapy versus capecitabine, the RFS rates were 56% and 50%, respectively (hazard ratio [HR], 0.80; P = .03); breast cancer-specific survival rates were 88% and 82%, respectively (HR, 0.62; P = .03); and overall survival rates were 62% and 56%, respectively (HR, 0.84; P = .16). With longer follow-up, standard chemotherapy remains superior to capecitabine among hormone receptor-negative patients (HR, 0.66; P = .02), but not among hormone receptor-positive patients (HR, 0.89; P = .43). Overall, 43.9% of patients have died (13.1% from breast cancer, 16.4% from causes other than breast cancer, and 14.1% from unknown causes). Second nonbreast cancers occurred in 14.1% of patients. CONCLUSION With longer follow-up, RFS remains superior for standard adjuvant chemotherapy versus capecitabine, especially in patients with hormone receptor-negative disease. Competing risks in this older population dilute overall survival benefits

    BACKGROUND: We examined the prognostic significance of circulating tumor cell (CTC) dynamics during treatment in metastatic breast cancer (MBC) patients receiving first-line chemotherapy. METHODS: Serial CTC data from 469 patients (2202 samples) were used to build a novel latent mixture model to identify groups with similar CTC trajectory (tCTC) patterns during the course of treatment. Cox regression was used to estimate hazard ratios for progression-free survival (PFS) and overall survival (OS) in groups based on baseline CTCs, combined CTC status at baseline to the end of cycle 1, and tCTC. Akaike information criterion was used to select the model that best predicted PFS and OS. RESULTS: Latent mixture modeling revealed 4 distinct tCTC patterns: undetectable CTCs (56.9% ), low (23.7%), intermediate (14.5%), or high (4.9%). Patients with low, intermediate, and high tCTC patterns had statistically significant inferior PFS and OS compared with those with undetectable CTCs (P < .001). Akaike Information Criterion indicated that the tCTC model best predicted PFS and OS compared with baseline CTCs and combined CTC status at baseline to the end of cycle 1 models. Validation studies in an independent cohort of 1856 MBC patients confirmed these findings. Further validation using only a single pretreatment CTC measurement confirmed prognostic performance of the tCTC model. CONCLUSIONS: We identified 4 novel prognostic groups in MBC based on similarities in tCTC patterns during chemotherapy. Prognostic groups included patients with very poor outcome (intermediate + high CTCs, 19.4%) who could benefit from more effective treatment. Our novel prognostic classification approach may be used for fine-tuning of CTC-based risk stratification strategies to guide future prospective clinical trials in MBC

    Effect of age on breast cancer outcomes in women with human epidermal growth factor receptor 2-positive breast cancer: results from a herceptin adjuvant trial.

    Previous research has suggested that young age at diagnosis is an independent risk factor for breast cancer recurrence and death. No prior studies have adequately controlled for human epidermal growth factor receptor 2 (HER2) status or anti-HER2 treatment. We sought to evaluate whether age was a prognostic or predictive factor in the HERA trial.SCOPUS: ar.jinfo:eu-repo/semantics/publishe

    Palkitsemisjärjestelmän kehittäminen : Case: Pankki X:n keskitetty palveluyksikkö

    Palkitsemisjärjestelmät tukevat henkilöstön motivaatiota sekä jaksamista työssä. Pankkialalla palkitsemisjärjestelmät ovat yleisiä. Sekä aineellinen että aineeton palkitseminen ovat tärkeitä palkitsemisjärjestelmissä. Opinnäytetyön tavoitteena oli kehittää palkitsemisjärjestelmää toimeksiantajamme Pankki X:n keskitetylle palveluyksikölle. Tälle kehittämistyölle oli tarve, koska palveluyksikön olemassa oleva palkitsemisjärjestelmä perustui vahvasti pankin tulokseen, eikä palveluyksikön henkilöstö voinut itse vaikuttaa siihen. Osana opinnäytetyötä toteutettiin kyselytutkimus, jossa keskitetyn palveluyksikön henkilöstöltä kysyttiin kyselylomakkeella näkemyksiä nykyisestä palkitsemismallista. Kyselyllä tiedusteltiin myös mielipiteitä tiimin ja yksilön palkitsemisesta, palkitsemisen perusteista, motivaatiotekijöistä ja työssä suoriutumisen mittareista. Saatuja vastauksia analysoitiin suhteessa työntekijöiden työvuosiin organisaatiossa. Kysely sisälsi sekä kvalitatiivista että kvantitatiivista tutkimusotetta. Tutkimustulokset osoittivat, että nykyisen palkitsemisjärjestelmän tulospalkkioon ja henkilöstörahastoon oltiin tyytyväisiä. Tiimin palkitseminen nousi esille tutkimuksen tuloksissa ja jotta tiimi voi kehittyä, on myös yksilöiden kehittymistä sekä kasvua tuettava. Tutkimustulosten ja taustateorioiden pohjalta muovautui suositus palkitsemisen kehittämiseen, jota tässä työssä kutsutaan "Meidän malliksi". Syntyneessä palkitsemismallissa motivoidaan ja palkitaan sekä yksilöä että tiimiä. Mallissa on luotu työkaluja tiimin kasvun ja kehittymisen avuksi, unohtamatta yksilöä. Suositus on käytännönläheinen sekä toteutettavissa. Opinnäytetyötä tullaan hyödyntämään toimeksiantajaorganisaatiossa palkitsemisen kehittämisessä, joten se on hyödyllinen. Palkitsemismallia pystytään jatkossa kehittämään organisaation tulevaisuuden haasteita ja tarpeita vastaavaksi.Reward systems support motivation of the staff and also coping of staff members. In banking reward systems are common. Both material and non-material rewarding are important parts of reward systems. The objective of the thesis was to develop a reward system for the centralized service unit of the client organisation. The development project was necessary, because the existing reward system was strongly based on the profit of the bank and the personnel of the service unit did not have an influence on rewarding. A survey was carried out as part of the thesis and a questionnaire was sent to the personnel of the service unit. They were asked about their views on the current reward system. Also opinions on rewarding the team and individuals, basis for rewarding, motivational factors and indicators of work performance were inquired. The answers were analyzed in relation to the duration of employment in the service unit. The survey contained elements of both quantitative and qualitative research methods. The findings showed that the personnel was content with the goal-sharing plan and personnel fund included in the current reward system. Rewarding the team was seen as an important factor. The personal development and growth should also be supported in order to enable team development. The recommendation for development of a rewarding system was built based on the findings and background theories. In this thesis the reward system is called “Our design” and it is designed to motivate and to reward both the team and individuals. The tools for supporting the growth and development of both the team and individuals are created in “Our design”. The recommended reward system is practical and feasible. The thesis is useful and it will be utilized in the client organization as they develop the rewarding of employees. In the future the reward system can be developed to meet the needs and challenges the organization will encounter

    Personalizing the treatment of women with early breast cancer : highlights of the st gallen international expert consensus on the primary therapy of early breast Cancer 2013

    No full text
    The 13th St Gallen International Breast Cancer Conference (2013) Expert Panel reviewed and endorsed substantial new evidence on aspects of the local and regional therapies for early breast cancer, supporting less extensive surgery to the axilla and shorter durations of radiation therapy. It refined its earlier approach to the classification and management of luminal disease in the absence of amplification or overexpression of the Human Epidermal growth factor Receptor 2 (HER2) oncogene, while retaining essentially unchanged recommendations for the systemic adjuvant therapy of HER2-positive and 'triple-negative' disease. The Panel again accepted that conventional clinico-pathological factors provided a surrogate subtype classification, while noting that in those areas of the world where multi-gene molecular assays are readily available many clinicians prefer to base chemotherapy decisions for patients with luminal disease on these genomic results rather than the surrogate subtype definitions. Several multi-gene molecular assays were recognized as providing accurate and reproducible prognostic information, and in some cases prediction of response to chemotherapy. Cost and availability preclude their application in many environments at the present time. Broad treatment recommendations are presented. Such recommendations do not imply that each Panel member agrees: indeed, among more than 100 questions, only one (trastuzumab duration) commanded 100% agreement. The various recommendations in fact carried differing degrees of support, as reflected in the nuanced wording of the text below and in the votes recorded in supplementary Appendix S1, available at Annals of Oncology online. Detailed decisions on treatment will as always involve clinical consideration of disease extent, host factors, patient preferences and social and economic constraints
