Oral Cannabis Extract for Secondary Prevention of Chemotherapy-Induced Nausea and Vomiting: Final Results of a Randomized, Placebo-Controlled, Phase II/III Trial. J Clin Oncol 2024:JCO2301836. [PMID: 39151115 DOI: 10.1200/jco.23.01836] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/24/2023] [Revised: 12/20/2023] [Accepted: 06/12/2024] [Indexed: 08/18/2024] Open
Abstract
PURPOSE The aim of this randomized, placebo-controlled, two-stage, phase II/III trial was to determine the efficacy of an oral cannabis extract in adults with refractory nausea and/or vomiting during moderately or highly emetogenic, intravenous chemotherapy despite guideline-consistent antiemetic prophylaxis. Here, we report results of the prespecified combined analysis including the initial phase II and subsequent phase III components. PATIENTS AND METHODS Study treatment consisted of oral capsules containing either tetrahydrocannabinol 2.5 mg plus cannabidiol 2.5 mg capsules (THC:CBD) or matching placebo, taken three times a day from days -1 to 5, in addition to guideline-consistent antiemetics. The primary measure of effect was the difference in the proportions of participants with no vomiting or retching and no use of rescue medications (a complete response) during hours 0-120 after the first cycle of chemotherapy on study (cycle A). RESULTS We recruited 147 evaluable of a planned 250 participants from 2016 to 2022. Background antiemetic prophylaxis included a corticosteroid and 5-hydroxytryptamine antagonist in 97%, a neurokinin-1 antagonist in 80%, and olanzapine in 10%. THC:CBD compared with placebo improved the complete response rate from 8% to 24% (absolute difference 16%, 95% CI, 4 to 28, P = .01), with similar effects for absence of significant nausea, use of rescue medications, daily vomits, and the nausea scale on the Functional Living Index-Emesis quality-of-life questionnaire. More frequent bothersome adverse events of special interest included sedation (18% v 7%), dizziness (10% v 0%), and transient anxiety (4% v 1%). There were no serious adverse events attributed to THC:CBD. CONCLUSION THC:CBD is an effective adjunct for chemotherapy-induced nausea and vomiting despite standard antiemetic prophylaxis, but was associated with additional adverse events. Drug availability, cultural attitudes, legal status, and preferences may affect implementation. Future analyses will evaluate the cost-effectiveness of THC:CBD.

Healthcare providers' adherence to breast cancer guidelines in Europe: a systematic literature review. Breast Cancer Res Treat 2020; 181:499-518. [PMID: 32378052 PMCID: PMC7220981 DOI: 10.1007/s10549-020-05657-8] [Citation(s) in RCA: 8] [Impact Index Per Article: 2.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 02/25/2020] [Accepted: 04/27/2020] [Indexed: 12/19/2022]
Abstract
Purpose Clinical guidelines’ (CGs) adherence supports high-quality care. However, healthcare providers do not always comply with CGs recommendations. This systematic literature review aims to assess the extent of healthcare providers’ adherence to breast cancer CGs in Europe and to identify the factors that impact on healthcare providers’ adherence. Methods We searched for systematic reviews and quantitative or qualitative primary studies in MEDLINE and Embase up to May 2019. The eligibility assessment, data extraction, and risk of bias assessment were conducted by one author and cross-checked by a second author. We conducted a narrative synthesis attending to the modality of the healthcare process, methods to measure adherence, the scope of the CGs, and population characteristics. Results Out of 8137 references, we included 41 primary studies conducted in eight European countries. Most followed a retrospective cohort design (19/41; 46%) and were at low or moderate risk of bias. Adherence for overall breast cancer care process (from diagnosis to follow-up) ranged from 54 to 69%; for overall treatment process [including surgery, chemotherapy (CT), endocrine therapy (ET), and radiotherapy (RT)] the median adherence was 57.5% (interquartile range (IQR) 38.8–67.3%), while for systemic therapy (CT and ET) it was 76% (IQR 68–77%). The median adherence for the processes assessed individually was higher, ranging from 74% (IQR 10–80%), for the follow-up, to 90% (IQR 87–92.5%) for ET. Internal factors that potentially impact on healthcare providers’ adherence were their perceptions, preferences, lack of knowledge, or intentional decisions. Conclusions A substantial proportion of breast cancer patients are not receiving CGs-recommended care. Healthcare providers’ adherence to breast cancer CGs in Europe has room for improvement in almost all care processes. CGs development and implementation processes should address the main factors that influence healthcare providers' adherence, especially patient-related ones. Registration: PROSPERO (CRD42018092884).

Abstract
Aims and Background Rarely are conclusions from clinical trials summarized in international consensus conferences and promptly transferred to patient care. The adjuvant therapy for colorectal cancer used in daily clinical practice in Italy is described and compared with the recommendations of the 1990 NIH Consensus Conference. Patients and Methods We audited prescriptions of adjuvant systemic therapies for Italian colorectal cancer patients in 82 centers during a fixed one-week period. Results Among 434 patients receiving adjuvant chemotherapy there were 139 (42.5%) colon cancer patients with N- and 169 (51.7%) with N+ regional nodal involvement. Treatment at academic centers, a young age, T4 and a low total number of lymph nodes removed at surgery were the factors potentially justifying the decision for adjuvant chemotherapy in stage II colon cancer patients. The most common chemotherapy used was a bolus of 5-fluorouracil/folinic acid for 6 months (75.8%). Adjuvant radiotherapy was not administered to 37 (38.5%) of 96 patients with stage II and III rectal cancer. Conclusions The study shows that a substantial proportion of patients on adjuvant treatment at a certain time point in a large enough sample of Italian centers are stage II (potential over-treatment) and that an under-treatment of stage II and III rectal cancer patients (lack of radiotherapy) occurs too often in daily clinical practice in this country.

Abstract
Breast surgery has evolved as a subspecialty of general surgery and requires a working knowledge of benign and malignant diseases, surgical techniques, shared decision-making with patients, collaboration with a multi-disciplinary team, and a basic foundation in surgical ethics. Ethics is defined as the practice of analyzing, evaluating, and promoting best conduct based upon available standards. As new information is obtained or as cultural values change, best conduct may be re-defined. In 2014, the Ethics Committee of the ASBrS acknowledged numerous ethical issues, specific to the practice of breast surgery. This independent review of ethical concerns was created by the Ethics Committee to provide a resource for ASBrS members as well as other surgeons who perform breast surgery. In this review, the professional, clinical, research and technology considerations that breast surgeons face are reviewed with guidelines for ethical physician behavior.

Abstract
We evaluated whether concurrent radiotherapy (RT) affected delivery and toxicity of adjuvant intravenous CMF (cyclophosphamide, methotrexate and 5-fluorouracil) in women with operable breast cancer. The medical charts of 321 consecutive breast cancer patients who received CMF either alone for 6 cycles, or for 4 cycles following of an anthracycline (A-CMF) were reviewed. One hundred forty-four women underwent radiotherapy concurrently with CMF. Optimal CMF delivery (success as opposite to failure) was defined as the combined achievement of an average relative dose intensity (aRDI) > or = 85% and an average percent of the total dose (aPTD) > or = 90% for the three drugs in the CMF regimen. Multivariate logistic regression analysis showed that concurrent-RT did not affect CMF delivery (OR for success 1.391 p=0.230). The sequential A-CMF regimen (OR for success 0.208, 95% C.I. 0.120-0.360, p<0.001) and age > or = 56 (OR for success 0.351, 95% C.I. 0.200-0.161, p<0.001) were independently associated with suboptimal CMF delivery. Moreover, concurrent RT was independently associated with increased leukopenia, thrombocytopenia, upper abdominal pain, mucositis and fatigue. Our retrospective analysis suggests that concurrent-RT has no impact on optimal CMF delivery, but it increases the burden of CMF-related toxicity.

Abstract
Purpose The prediction of breast cancer recurrence is a crucial factor for successful treatment and follow-up planning. The principal objective of this study was to construct a novel prognostic model based on support vector machine (SVM) for the prediction of breast cancer recurrence within 5 years after breast cancer surgery in the Korean population, and to compare the predictive performance of the model with the previously established models. Methods Data on 679 patients, who underwent breast cancer surgery between 1994 and 2002, were collected retrospectively from a Korean tertiary teaching hospital. The following variables were selected as independent variables for the prognostic model, by using the established medical knowledge and univariate analysis: histological grade, tumor size, number of metastatic lymph node, estrogen receptor, lymphovascular invasion, local invasion of tumor, and number of tumors. Three prediction algorithms, with each using SVM, artificial neural network and Cox-proportional hazard regression model, were constructed and compared with one another. The resultant and most effective model based on SVM was compared with previously established prognostic models, which included Adjuvant! Online, Nottingham prognostic index (NPI), and St. Gallen guidelines. Results The SVM-based prediction model, named 'breast cancer recurrence prediction based on SVM (BCRSVM),' proposed herein outperformed other prognostic models (area under the curve=0.85, 0.71, 0.70, respectively for the BCRSVM, Adjuvant! Online, and NPI). The BCRSVM evidenced substantially high sensitivity (0.89), specificity (0.73), positive predictive values (0.75), and negative predictive values (0.89). Conclusion As the selected prognostic factors can be easily obtained in clinical practice, the proposed model might prove useful in the prediction of breast cancer recurrence. The prediction model is freely available in the website (http://ami.ajou.ac.kr/bcr/).

Adjuvant chemotherapy of pT1a and pT1b breast carcinoma: results from the NEMESI study. BMC Cancer 2012; 12:158. [PMID: 22545982 PMCID: PMC3404902 DOI: 10.1186/1471-2407-12-158] [Citation(s) in RCA: 12] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Download PDF] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/07/2011] [Accepted: 04/30/2012] [Indexed: 12/27/2022] Open
Abstract
BACKGROUND The prognosis of pT1a-pT1b breast cancer (BC) used to be considered very good, with a 10-y RFS of 90%. However, some retrospective studies reported a 10-y RFS of 81%-86% and suggested benefit from adjuvant systemic therapy. METHODS To evaluate the variables that determined the choice of adjuvant chemotherapy and the type of chemotherapy delivered in pT1a-pT1b BC, we analysed the small tumours enrolled in the NEMESI study. RESULTS Out of 1,894 patients with pathological stage I-II BC enrolled in NEMESI, 402 (21.2%) were pT1a-pT1b. Adjuvant chemotherapy was delivered in 127/402 (31.59%). Younger age, grading G3, high proliferative index, ER-negative and HER2-positive status were significantly associated with the decision to administer adjuvant chemotherapy. An anthracycline without taxane regimen was administered in 59.1% of patients, anthracycline with taxane in 24.4%, a CMF-like regimen in 14.2% and taxane in 2.4%. Adjuvant chemotherapy was administered in 88.4% triple-negative and 73.46% HER2-positive pT1a-pT1b BC. Adjuvant trastuzumab was delivered in 30/49 HER2-positive BC (61.2%). CONCLUSIONS Adjuvant chemotherapy was delivered in 31.59% T1a-pT1b BC treated at 63 Italian oncological centres from January 2008 to June 2008. The choice to deliver chemotherapy was based on biological prognostic factors. Anthracycline-based chemotherapy was administered in 83.5% patients.

Abstract
INTRODUCTION Adjuvant treatments are usually decided according to guidelines. However, many individual factors, such as performance status, patient refusal, complex interactions between factors (eg, discrepancies between grade and Ki 67), and complex clinical features (borderline age or tumor size) may introduce discrepancies. The aim of this study was to quantify discrepancies between local guidelines and patient management. PATIENTS AND METHODS From 2003 and 2005, 581 consecutive patients underwent surgery for invasive breast cancer. Patient, tumor characteristics, and outcome were recorded. We compared patient characteristics according to whether local guidelines had been followed. RESULTS In 90% of cases local guidelines were followed. Patients who inadequately did not receive chemotherapy were older (P < .0001), with positive hormonal receptor status (P = .02), and less aggressive tumors (P < .05). Main reasons for not administering chemotherapy were age, patient refusal, and micrometastatic node involvement. Patients from the other discordant group (ie, those who inadequately received chemotherapy), had larger (P = .01) and more aggressive tumors (P < .0001). In these cases, the clinical decision was mainly based on multifocal tumors and limit lower age. For disease-free survival (DFS), we found a significant difference between groups (P = .001). The best overall survival and DFS was found for patients who adequately received no adjuvant treatment. Survival among groups were similar when stratified on treatment modality. CONCLUSION The main reasons for discrepancy were age (advanced or lower limit), patient refusal, and multifocal tumors. In this series, deviations from recommendations had no affect on survival and raised the question of new indications for chemotherapy such as multifocal tumors.

Abstract
Background Great variability in breast cancer (BC) treatment practices according to patient, tumour or organisation of care characteristics has been reported but the relation between these factors is not well known. In two French regions, we measured compliance with Clinical Practice Guidelines for non-metastatic BC care management and identified factors associated with non-compliance at clinical and organisational levels. Methods Eligible patients had invasive unilateral BC without distant metastases and at least two contacts with one of the two regional healthcare systems (2003-2004) in the first year after diagnosis. Medical data were collected from patient medical records in all public and private hospitals (99 hospitals). The care process was defined by 20 criteria: clinical decisions for treatment and therapeutic procedures. Each criterion was classified according to level of compliance ("Compliant", "Justifiable" and "Not Compliant") and factors of non-compliance were identified (mixed effect logistic regression). Results 926 women were included. Non-compliance with clinical decisions for treatment was associated with older patient age (OR 2.1; 95%CI: 1.3-3.6) and region (OR 3.0; 95%CI: 1.2-7.4). Non-compliance with clinical decisions for radiotherapy was associated with lymph node involvement or the presence of peritumoural vascular invasion (OR 1.5; 95%CI: 1.01-2.3) and non-compliance with overall treatment (clinical decisions for treatment + therapeutic procedures) was associated with the presence of positive lymph nodes (OR 2.0; 95%CI: 1.2-3.3), grade III versus grade I (OR 2.9; 95%CI: 1.4-6.2), and one region of care versus another (OR 3.5; 95%CI: 1.7-7.1). Finally, heterogeneity of compliance in overall treatment sequence was identified between local cancer units (p < 0.05). Conclusion This study provides interesting insights into factors of non-compliance in non-metastatic BC management and could lead to quality care improvements.

Abstract
PURPOSE Pretreatment preferences for adjuvant therapy were examined and compared with actual treatment received. PATIENTS AND METHODS Before definitive surgery, women with node-negative breast cancer were asked to indicate their preference for adjuvant therapy in response to 3 different clinical scenarios. The scenarios provided precise risk, benefit, and side effect information with low-, moderate-, or high-risk risk of death from breast cancer. Contingency table and Spearman rank correlation coefficients were used to examine associations. Kruskal-Wallis rank sum tests were used for group comparisons, with the Friedman rank sum test being used for correlated samples. RESULTS A total of 75 women enrolled between February 2002 and April 2005; 24% were aged > 65 years. After definitive surgery, 21% of women had ductal carcinoma in situ, and 89% had receptor-positive disease. There was a significant correlation between risk of recurrence and aggressiveness of treatment preferred (P < .001). After surgical staging, the high-risk group received more aggressive treatment compared with the low-risk group (P = .004). In the 51 women with invasive receptor-positive tumors, there was a significant difference (P = .002) in aggressiveness of treatment received based on risk of recurrence. Only 45% of the women received what they had preferred for the level of their risk before surgery. Women were more likely to receive a less aggressive therapy than they preferred initially (P = .0002). CONCLUSION This study is among the first to correlate pretreatment preference for therapy with the actual therapy received. Less than half of women received their indicated preference before definitive surgery, with most women receiving less aggressive therapy. Future studies will need to examine this discrepancy.

Abstract
BACKGROUND There are no evidence-based benchmarks to establish optimal rates of use of endocrine therapy in the whole breast cancer population. Reported utilization rates vary widely. The aim of the study was to estimate the optimal proportion of breast cancer patients who should receive endocrine therapy based on treatment guideline recommendations and to compare this with actual treatment rates. METHODS An optimal endocrine therapy utilization tree was constructed based on indications from evidence-based treatment guidelines. Frequency data on patient and tumour attributes were obtained from Australian cancer registries where possible and merged with the guideline recommendations to calculate the optimal utilization rate. These were compared with actual proportions obtained from published reports. RESULTS According to the best available evidence, the proportion of invasive breast cancer patients in whom endocrine therapy is indicated at diagnosis is 67%. Endocrine therapy is under-utilized in Australia (actual utilization rate 41%), and USA (35%), but approximate the benchmark rate in the UK (75%) and Italy (63%). CONCLUSION This evidence-based model provides a benchmark for optimal endocrine therapy utilization rates in the breast cancer population, and comparison of best practice evidence and actual treatment. The results show an underutilization of endocrine therapy in Australia and the USA, with more appropriate utilization in the UK and Italy.

Abstract
OBJECTIVES The study's objectives were to observe and describe chemotherapy treatment (CT) used in breast cancer (BC) patients in Spain and estimate its cost. METHODS Multi-centre and transversal study, which included consecutive BC patients treated with chemotherapy between 10 and 15 May 2004 in 110 centres throughout Spain. Information was gathered on the general characteristics of the centres, the patient data and the treatments administered. This information was collected prospectively based on the data available in the pharmacy service and/or the patient's clinical history. The following information was requested: demographic, clinical, CT administered during the week of the study, established guidelines, inclusion in clinical trials and the direct costs of the medication. RESULTS A total of 2,134 patients were included (99.7% women) from 16 autonomous communities and the average age was 51.5. The majority of the treatments were administered in general hospitals (89.7%), public or public health partnership hospitals (91.5%) and level 3 specialist hospitals (64.5%). Among these patients, 120 (5.6%) received treatment as part of a clinical study. A total of 51% of patients received adjuvant or neoadjuvant treatment, mainly for stage IIA disease (28.7%). A total of 1011 patients presented metastatic disease (MD). The estimated average cost of chemotherapy treatment was euro428.5 per cycle and the group of patients with MD incurred the greatest cost (euro640.4 per cycle). CONCLUSIONS The results show the current situation of CT for BC in Spain and a great deal of variability is observed both in the use of drugs as well as in the associated costs.

Abstract
BACKGROUND We sought to determine the significance of Ki-67, one of the tumor cell proliferation markers, as a useful prognostic factor in early breast cancer. METHODS A total of 1080 consecutive patients with stage I or II breast cancer that underwent surgery between 1998 and 2003 were enrolled. Patients were categorized on the basis of the 2007 St. Gallen consensus and Adjuvant! Online. The expression of Ki-67 in the tumor was assayed by immunohistochemistry (cutoff value, 10%). RESULTS Univariate analysis determined that tumor size, lymph node involvement, histologic grade, estrogen receptor, progesterone receptor, bcl-2, and Ki-67 (> or =10%) were statistically significant for both overall survival (OS) and distant metastasis-free survival (DFS). Of these factors, lymph node involvement and high Ki-67 expression were identified as independent prognostic factors for OS and DFS on the basis of multivariate analysis. The survivals of intermediate- and high-risk groups according to 2007 St. Gallen consensus were further separated by Ki-67 expression level (5-year DFS rate = 91.9% vs. 86.3% for Ki-67 < 10% and > or = 10%, respectively in intermediate-risk group (P = .01); 5-year DFS rate = 82.5% vs. 61.4% for Ki-67 < 10% and > or = 10%, respectively in high-risk group (P = .01)). The survivals of low- and high-risk groups according to Adjuvant! Online were further separated by Ki-67 expression level (5-year DFS rate = 97.8% vs. 89.5% for Ki-67 < 10% and > or = 10%, respectively in low-risk group (P = .02); 5-year DFS rate = 9.4% vs. 82.6% for Ki-67 < 10% and > or = 10% in high-risk group (P = .005)). CONCLUSIONS Ki-67 is an independent prognostic factor for DFS and OS in early breast cancer and can provide additional prognostic information on the risk stratification with the use of the 2007 St. Gallen consensus and Adjuvant! Online.

Abstract
BACKGROUND Tamoxifen has a remarkable impact on the outcome of oestrogen receptor (ER)-positive breast cancer. Without proven benefits, tamoxifen is occasionally prescribed for women with ER-negative disease. This population-based study aims to estimate the impact of tamoxifen on the outcome of ER-negative disease. METHODS We identified all women (n = 528) diagnosed with ER-negative invasive breast cancer between 1995 and 2005. With Cox regression analysis, we calculated breast cancer mortality risks of patients treated with tamoxifen compared with those treated without tamoxifen. We adjusted these risks for the individual probabilities (propensity scores) of having received tamoxifen. RESULTS Sixty-nine patients (13%) with ER-negative disease were treated with tamoxifen. Five-year disease-specific survival for women treated with versus without tamoxifen were 62% [95% confidence interval (CI) 48% to 76%] and 79% (95% CI 75% to 83%), respectively (P(Log-rank) < 0.001). For ER-negative patients, risk of death from breast cancer was significantly increased in those treated with tamoxifen compared with patients treated without tamoxifen (adjusted hazard ratio = 1.7, 95% CI 1.1-2.9, P = 0.031). CONCLUSION Our results show that patients with ER-negative breast cancer treated with tamoxifen have an increased risk of death from their disease. Tamoxifen use should be avoided for these patients.

Abstract
BACKGROUND The NORA study is a prospective longitudinal cohort study aiming at investigating treatment in patients with early breast cancer. Here, we present the impact of the St Gallen recommendations on clinical practice. PATIENTS AND METHODS We compared adjuvant strategies in patients enrolled in 2000-2002 to those in 2003-2004 to verify the impact of the 2003 St Gallen recommendations. RESULTS The use of aromatase inhibitors (AIs) doubled: 65/629 patients (10.3%) vs 100/458 patients (21.8) (P < 0.0001). Following chemotherapy, AIs were administered in 8.5% of the retrospective cohort and in 15.1% of the prospective one (P < 0.0001). The use of taxanes plus hormones dropped (P = 0.0026), but not when used as single agents. A marked increase was observed in the use of anthracycline-based chemotherapy (46.3% vs 65.2%), mainly three-drug regimens (33.3% vs 46.6%). CONCLUSION Our results suggest that the St Gallen recommendations have had a major impact on clinical practice.

Abstract
Despite lower incidence, African American women are at increased risk of dying from breast cancer relative to their European American counterparts. Although there are key differences in both screening behavior and tumor characteristics, an additional part of this mortality difference may lie in the fact that African American women receive suboptimal adjuvant chemotherapy and may receive suboptimal hormonal therapy, therapies that are known to increase survival. The authors consider ethnic differences in the psychosocial factors that have been shown to relate to poor screening adherence and consider how they may influence adherence to breast cancer adjuvant treatment, thus the receipt of suboptimal adjuvant chemo or hormonal therapy. To this end, they review ethnic differences in cognitive, emotional, and social network variables. Psychosocial variables should be included in research designed to understand cancer disparities as well interventions that can be tailored to culturally diverse populations to improve treatment adherence.

Abstract
In this paper, we review the literature on psychosocial influences on breast cancer screening and treatment adherence with an eye to identifying common cognitive, emotional, and social network factors that may lead to poor screening adherence and suboptimal treatment in the case of diagnosed breast cancer. Nonadherence to breast cancer screening and treatment guidelines can significantly and negatively impact the prospects for prevention and control of breast cancer. Psychosocial factors are an especially important focus for research, inasmuch as belief structures and psychosocial characteristics (such as patterns of emotion regulation and the quality of social relations) are modifiable and are, thus, eminently suitable to intervention.

Abstract
BACKGROUND The incidence of breast cancer increases with age, and the disease affects many older women; however, attitudes about prevention and treatment of breast cancer vary based on the patient's age. Older women have less access to clinical trials and fewer opportunities for treatment with innovative therapies. The National Oncological Research observatory on Adjuvant therapy in breast cancer (NORA) study was a cohort study designed to obtain information about adjuvant strategies for treatment of breast cancer after surgery, patterns of recurrence, and possible correlations between cancer-related events and biological factors. PATIENTS AND METHODS This report describes patient characteristics, disease status, and local and systemic adjuvant treatments in a population of breast cancer patients aged >or=65 years. The NORA study consecutively enrolled >3500 patients from 2000 through 2002 at 77 Italian hospitals; of these, 1085 were aged >or=65 years. Data on patient characteristics, cancer presentation, and treatments were analyzed to identify possible relationships between these factors and age. RESULTS The findings indicate that age is significantly related to later diagnosis and different patterns of treatment. Choice of adjuvant systemic treatment was primarily related to hormone receptor status and tumor stage but was strongly influenced by the patient's age; there was a proportional relationship between endocrine treatment and increasing age. Cyclophosphamide, methotrexate, and 5-fluorouracil as well as anthracyclines were widely used, but the use of taxanes was limited to a very small percentage of patients. CONCLUSIONS The findings of the NORA study may help to change attitudes that currently exclude a significant proportion of breast cancer patients from secondary prevention policies, more active treatment strategies, and clinical research trials based on age.

Abstract
Treatment guidelines are useful tools that enable physicians to integrate the latest clinical research into their practices. The large volume of rapidly evolving clinical data in breast cancer has been summarised and incorporated into treatment recommendations by well-known and reliable institutions, including the National Comprehensive Cancer Network, the American Society for Clinical Oncology, the European Society for Medical Oncology and the St. Gallen International Consensus Panel. Adjuvant therapy is a key component of breast cancer treatment, and many of the current consensus guidelines now recognise the important role of the aromatase inhibitors as an alternative to or in sequence after tamoxifen, hitherto the standard adjuvant treatment of choice for receptor-positive women. Data from ongoing trials such as the Breast International Group 1-98 trial and those still in the accrual phase will be forthcoming and will likely result in a further refinement of treatment recommendations over the course of the next few years. Despite the availability of such guidelines, however, there is evidence that adherence to and implementation of treatment recommendations is less than optimal. Further research is needed to determine more effective means of disseminating those clinical recommendations that can have a significant impact on treatment strategies and ultimately improve outcomes in breast cancer.

Abstract
BACKGROUND Despite recommendations contained in international guidelines, factors such as the type of oncology centre, geographic distribution and the introduction of scientific advances into clinical practice can influence the choice of recommended treatment for early breast cancer. The NORA study is a prospective, longitudinal cohort study aimed at investigating tumour characteristics, treatment modalities, and other factors that influence therapeutic choices in early breast cancer patients who have undergone mastectomy or breast-conserving surgery (BCS). PATIENTS AND METHODS From January 2000 to early 2004, we collected data on methods of cancer diagnosis, type of surgery and adjuvant medical treatment administered to the first 10 consecutive patients treated in 2000-2002 and the first 20 consecutive patients in 2003 and 2004 at 71 oncology centres in Italy, with the approval of the ethical committee at each centre. RESULTS Approximately one-quarter of the cases (26.5%) were detected through screening programmes. BCS was performed in 63.7% and sentinel node biopsy (SNB) occurred in 11.1% of the patients. Of the 3515 total cases, 56.5% were node-negative. Grade 2 cancers comprised 51.3%, and 66.2% were hormone-receptor positive (ER+/PgR+). Chemotherapy (CHT) followed by hormone therapy (HT) was the most prescribed treatment (48.5%). CHT was mainly anthracycline-based (52.9%) and most patients received tamoxifen alone (77.7%) or after CHT (85.2%). For node-negative patients, HR+ and menopause status are the factors influencing the choice to add HT after CHT; patients with HR+ and pT4 tumours are more likely to receive HT instead of CHT. In node-positive patients, the addition of HT is influenced by HR+ status, the opportunity to have HT instead of CHT, and menopause. CONCLUSIONS NORA is the first large cohort study to describe the factors that influence therapeutic choices in early breast cancer. Understanding these findings can help physicians in daily clinical practice.

Abstract
PURPOSE The value of adjuvant tamoxifen after chemotherapy for premenopausal women with breast cancer has not been adequately assessed. PATIENTS AND METHODS Between 1993 and 1999, International Breast Cancer Study Group Trial 13-93 enrolled 1,246 assessable premenopausal women with axillary node-positive, operable breast cancer. All patients received chemotherapy (cyclophosphamide plus either doxorubicin or epirubicin for four courses followed by immediate or delayed classical cyclophosphamide, methotrexate, and fluorouracil for three courses), which was followed by either tamoxifen (20 mg daily) for 5 years or no further treatment. The primary end point was disease-free survival (DFS). Tumors were classified as estrogen receptor (ER) -positive (n = 735, 59%) if immunohistochemical (IHC) or ligand-binding assays (LBA) were clearly positive. The ER-negative group included all other tumors (n = 511, 41%). A subset of the ER-negative group was defined as ER absent (n = 108, 9%) if IHC staining was none or if the LBA result was 0 fmol/mg cytosol protein. The median follow-up time was 7 years. RESULTS Tamoxifen improved DFS in the ER-positive cohort (hazard ratio [HR] for tamoxifen v no tamoxifen = 0.59; 95% CI, 0.46 to 0.75; P < .0001) but not in the ER-negative cohort (HR = 1.02; 95% CI, 0.77 to 1.35; P = .89). Tamoxifen had a detrimental effect on patients with ER-absent tumors compared with no tamoxifen in an unplanned exploratory analysis (HR = 2.10; 95% CI, 1.03 to 4.29; P = .04). Patients with ER-positive tumors who achieved chemotherapy-induced amenorrhea had a significantly improved outcome (HR for amenorrhea v no amenorrhea = 0.61; 95% CI, 0.44 to 0.86; P = .004), whether or not they received tamoxifen. CONCLUSION Tamoxifen after adjuvant chemotherapy significantly improved treatment outcome in premenopausal patients with endocrine-responsive disease, but its use as adjuvant therapy for patients with ER-negative tumors is not recommended.

Abstract
OBJECTIVE There is a perception that many drug usage evaluations do not widely influence prescribing behaviour. The aim of this study was to critically evaluate recent journal articles which fit the Medline definition for Drug Utilization Review (DUR) and which also cover multiple healthcare sites. METHODS PubMed (National Library of Medicine, NLM) (2003, 2004) was searched using the MeSH topic 'drug utilization'. Retrieved studies were evaluated to ascertain those describing a DUR (measuring drug use against specific criteria). These were subdivided according to whether the DUR was conducted at one site or across many. The multi-centre DURs were critically reviewed, including evaluating whether all phases of a quality cycle were completed and determining aspects of design such as whether the study was prospective or retrospective, any interventions conducted and provision of feedback. RESULTS A total of 646 unique articles were retrieved. Of these, 495 (77%) did not meet the definition for DUR, while 151 (23%) articles did. Thirty-five (5%) described English language multi-centre DURs; ethics approval was obtained in ten of these and 18 were carried out retrospectively. In all 35 studies some comparator or standard was used, but only eight conducted an intervention and only three provided feedback to the prescribers. CONCLUSION Most DURs were not conducted across a number of centres. Of the recent published multi-centre DURs most presented only an initial audit and did not complete the quality cycle with feedback, intervention and re-audit. To widely influence prescribing behaviour, the full cycle is required with involvement of as many sites as possible to achieve improvements across many jurisdictions.

Abstract
Breast cancer treatment guidelines are not uniformly followed in clinical practice, with evidence for substantial variations in treatment patterns, quality of care, and patient outcomes among and within countries. The factors that drive treatment decisions are unclear. Furthermore, the impact of different treatment strategies on survival is poorly understood outside the clinical trial setting. Sources of patterns of care information often have limitations in completeness, quality, timeliness of reporting, and relevance to the larger population. Patterns of care studies frequently lack details on cancer stage at diagnosis, tumor biology, and treatment received. It is difficult to compare data between studies and/or track changes over time because of variations in data sources and collection techniques. Thus, the design and implementation of a global registry is sorely needed in order to prospectively evaluate worldwide patterns of care and outcomes in patients with breast cancer. Components of this registry should include random selection of centers of variable practice settings in multiple countries and accurate and rapid data reporting at prestudy and follow-up timepoints. Data collected would include tumor and demographic factors, staging information, treatment rendered, and survival. Variables that influenced the treatment selected would be assessed. This unique international effort would allow the development of strategies to improve diagnostic and treatment-related standards of care and survival outcomes, thus reducing the breast cancer burden worldwide.
