RESUMEN

The purpose of the study is to determine the effects of the BIG 1-98 treatments on bone mineral density. BIG 1-98 compared 5-year adjuvant hormone therapy in postmenopausal women allocated to four groups: tamoxifen (T); letrozole (L); 2-years T, 3-years L (TL); and 2-years L, 3-years T (LT). Bone mineral density T-score was measured prospectively annually by dual energy X-ray absorption in 424 patients enrolled in a sub-study after 3 (n = 150), 4 (n = 200), and 5 years (n = 74) from randomization, and 1 year after treatment cessation. Prevalence of osteoporosis and the association of C-telopeptide, osteocalcin, and bone alkaline phosphatase with T-scores were assessed. At 3 years, T had the highest and TL the lowest T-score. All arms except for LT showed a decline up to 5 years, with TL exhibiting the greatest. At 5 years, there were significant differences on lumbar T-score only between T and TL, whereas for femur T-score, differences were significant for T versus L or TL, and L versus LT. The 5-year prevalence of spine and femur osteoporosis was the highest on TL (14.5 %, 7.1 %) then L (4.3 %, 5.1 %), LT (4.2 %, 1.4 %) and T (4 %, 0). C-telopeptide and osteocalcin were significantly associated with T-scores. While adjuvant L increases bone mineral density loss compared with T, the sequence LT has an acceptable bone safety profile. C-telopeptide and osteocalcin are useful markers of bone density that may be used to monitor bone health during treatment. The sequence LT may be a valid treatment option in patients with low and intermediate risk of recurrence.

RESUMEN

BACKGROUND: In the oncology setting, there has been increasing interest in evaluating treatment outcomes in terms of quality of life and patient satisfaction. The aim of our study was to investigate the determinants of patient satisfaction, especially the relationship between quality of life and satisfaction with care and their changes over time, in curative treatment of cancer outpatients. METHODS: Patients undergoing ambulatory chemotherapy or radiotherapy in two centers in France were invited to complete the OUT-PATSAT35, at the beginning of treatment, at the end of treatment, and three months after treatment. This questionnaire evaluates patients' perception of doctors and nurses, as well as other aspects of care organization and services. Additionally, for each patient, socio-demographic and clinical characteristics, and self-reported quality of life data (EORTC QLQ-C30) were collected. RESULTS: Of the 691 patients initially included, 561 answered the assessment at all three time points. By cross-sectional analysis, at the end of the treatment, patients who experienced a deterioration of their global health reported less satisfaction on most scales (p ≤ 0.001). Three months after treatment, the same patients had lower satisfaction scores only in the evaluation of doctors (p ≤ 0.002). Furthermore, longitudinal analysis showed a significant relationship between a deterioration in global health and a decrease in satisfaction with their doctor and, conversely, between an improvement in global health and an increase in satisfaction on the overall satisfaction scale. Global health at baseline was largely and significantly associated with all satisfaction scores measured at the following assessment time points (p < 0.0001). Younger age (<55 years), radiotherapy (versus chemotherapy) and head and neck cancer (versus other localizations) were clinical factors significantly associated with less satisfaction on most scales evaluating doctors. CONCLUSIONS: Pre-treatment self-evaluated global health was found to be the major determinant of patient satisfaction with care. The subsequent deterioration of global health, during and after treatment, emphasized the decrease in satisfaction scores, mainly in the evaluation of doctors. Early initiatives aimed at improving the delivery of care in patients with poor health status should lead to improved perception of the quality of care received.

RESUMEN

While the places and causes of death are the subject of abundant literature, the circumstances surrounding the end of life, the ultimate phase of existence, remain largely not explored in France. The pathways through different living places taken by people aged 80 and over during the last month of existence and the factors associated with them are described thanks to the unique information and data collected by the "End of Life in France" survey.

RESUMEN

BACKGROUND: The "Patients' Rights and End of Life Care" Act came into force in France in 2005. It allows withholding/withdrawal of life-support treatment, and intensified use of medications that may hasten death through a double effect, as long as hastening death is not the purpose of the decision. It also specifies the requirements of the decision-making process. This study assesses the situation by examining the frequency of end-of-life decisions by patients' and physicians' characteristics, and describes the decision-making processes. METHODS: We conducted a nationwide retrospective study of a random sample of adult patients who died in December 2009. Questionnaires were mailed to the physicians who certified/attended these deaths. Cases were weighted to adjust for response rate bias. Bivariate analyses and logistic regressions were performed for each decision. RESULTS: Of all deaths, 16.9% were sudden deaths with no information about end of life, 12.2% followed a decision to do everything possible to prolong life, and 47.7% followed at least one medical decision that may certainly or probably hasten death: withholding (14.6%) or withdrawal (4.2%) of treatments, intensified use of opioids and/or benzodiazepines (28.1%), use of medications to deliberately hasten death (i.e. not legally authorized) (0.8%), at the patient's request (0.2%) or not (0.6%). All other variables held constant, cause of death, patient's age, doctor's age and specialty, and place of death, influenced the frequencies of decisions. When a decision was made, 20% of the persons concerned were considered to be competent. The decision was discussed with the patient if competent in 40% (everything done) to 86% (intensification of alleviation of symptoms) of cases. Legal requirements regarding decision-making for incompetent patients were frequently not complied with. CONCLUSIONS: This study shows that end-of-life medical decisions are common in France. Most are in compliance with the 2005 law (similar to some other European countries). Nonetheless, the study revealed cases where not all legal obligations were met or where the decision was totally illegal. There is still a lot to be done through medical education and population awareness-raising to ensure that the decision-making process is compatible with current legislation, the physician's duty of care and the patient's rights.

RESUMEN

BACKGROUND: The aim of this study was to identify factors associated with satisfaction with care in cancer patients undergoing ambulatory treatment. We investigated associations between patients' baseline clinical and socio-demographic characteristics, as well as self-reported quality of life, and satisfaction with care. METHODS: Patients undergoing ambulatory chemotherapy or radiotherapy in 2 centres in France were invited, at the beginning of their treatment, to complete the OUT-PATSAT35, a 35 item and 13 scale questionnaire evaluating perception of doctors, nurses and aspects of care organisation. Additionally, for each patient, socio-demographic variables, clinical characteristics and self-reported quality of life using the EORTC QLQ-C30 questionnaire were recorded. RESULTS: Among 692 patients included between January 2005 and December 2006, only 6 were non-responders. By multivariate analysis, poor perceived global health strongly predicted dissatisfaction with care (p < 0.0001). Patients treated by radiotherapy (vs patients treated by chemotherapy) reported lower levels of satisfaction with doctors' technical and interpersonal skills, information provided by caregivers, and waiting times. Patients with primary head and neck cancer (vs other localisations), and those living alone were less satisfied with information provided by doctors, and younger patients (< 55 years) were less satisfied with doctors' availability. CONCLUSIONS: A number of clinical of socio-demographic factors were significantly associated with different scales of the satisfaction questionnaire. However, the main determinant was the patient's global health status, underlining the importance of measuring and adjusting for self-perceived health status when evaluating satisfaction. Further analyses are currently ongoing to determine the responsiveness of the OUT-PATSAT35 questionnaire to changes over time.

RESUMEN

BACKGROUND: Persons with a diagnosis of severe mental illness have a life expectancy that is 20 years lower than the general population, and they are disproportionately affected by cardiovascular disorders. Improving the management of cardiovascular risk is one of the main challenges for the public health system. In the care pathway of persons with a diagnosis of severe mental illness, a better understanding of limiting and facilitating factors is required. The objective was to include persons with a diagnosis of severe mental illness, carers, and primary and mental health professionals in the creation and evaluation (feasibility) of a health promotion program designed to improve cardiovascular risk management through empowerment. METHODS: This study combines a mixed methodology with qualitative and quantitative components. A multicenter prospective qualitative study was conducted in seven mental health units in France and was coordinated by a steering committee composed of persons with a diagnosis of severe mental illness, carers, and primary and mental health professionals. RESULTS: This health promotion program must enable persons with a diagnosis of severe mental illness to assert their right to self-determination and to exercise greater control over their lives, beyond their diagnosis and care. Following a preliminary feasibility study, the effectiveness of this new tool will be evaluated using a randomized controlled trial in a second study. CONCLUSIONS: The findings can be used by health organizations as a starting point for developing new and improved services for persons with a diagnosis of severe mental illness.Trial registration Clinical Trials Gov NCT03689296.

RESUMEN

Several studies have suggested rural health disadvantages. In France, studies on rural-urban patterns of lung cancer survival have yielded conflicting results. The aim of this analysis was to determine whether rural residence was associated with poor survival in three French counties. The database consisted of all primary lung cancer cases diagnosed in 2000 and 2001 collected through the Doubs cancer registry. A degree of rurality, obtained from socio-demographic and farming parameters of the 1999 French census treated with factor analysis, was attributed to each patient according to his/her place of residence. Among the 802 patients, 21% resided in rural areas, 11% were semi-urban inhabitants and 68% were urban residents. Survival differed significantly between these three rurality categories (p=0.04), with 2-year survival rates of 18, 29 and 24%, respectively. Using a Cox model, rural areas were significantly correlated with poor survival as compared with semi-urban areas (OR=1.42; 95% confidence interval=1.06-1.90; p=0.02). There was no survival difference between semi-urban and urban patients (OR=1.18; 95% confidence interval=0.91-1.53; p=0.21). Patient and tumour characteristics, especially stage and staging procedures, as well as first line treatment, did not vary with the degree of rurality. In conclusion, rurality has to be considered as a strong prognostic factor. Several intricate factors might be hypothesized such as increasing time to diagnosis leading to heavier tumour burden, worse treatment compliance and socioeconomic status. Before practical interventions can be proposed, prospective studies are warranted with further definition of rural risk factors for decreased survival in rural lung cancer patients.

RESUMEN

OBJECTIVE: The aim of this study was to measure women's preferences about decision-making and their impact to participate or not to a hypothetical randomised controlled trial (RCT). METHODS: We surveyed prospectively breast cancer patients invited to participate in a clinical RCT (group 1a=201 acceptances, group 1b=66 refusals) or not invited (group 2=188). All women had the same treatment. RESULTS: Decision-making preferences of patients who had refused clinical RCT entry were more patient's centred (72.3%) compared to those of patients who accepted (35.0%, P<0.001). Altruism was not a significant determinant of patients' participation. Randomisation was considered acceptable in 52.0% (group 1a) compared to 16.9% and 21.1% for group 1b or group 2, respectively (P<0.001). It was the main predictor of willingness to participate in a hypothetical RCT (adjusted odds ratio (OR(adj)) 4.6; 95% confidence interval [2.7-7.7]; P<0.001) with the patient group allocation (OR(adj) group 1a=5.0 [2.9-8.7]; group 1b=0.2 [0.0-0.8]; group 2=1 [referent]; P<0.001). After multivariate adjustment, willingness to participate was also significantly related with medical decision-making preferences (OR(adj) 2.2 [1.0-4.9]; P=0.045), with the feeling of being unable to refuse a doctor's proposal (OR(adj) 1.8 [1.1-3.2]; P=0.031), and with satisfaction with doctors' communication (OR(adj) 3.1 [1.5-7.8]; P<0.001). CONCLUSIONS: Patients' acceptance to participate in a RCT is preferred to be doctor's decision, whereas refusal is a personal one. When proposing a RCT, doctors must deal with patients' a priori negative feelings about randomisation. They should thoroughly discuss the reasons for and importance of randomisation as well as the other aspects of participating in the trial in order to give patients all of the information they need to make an informed decision.

RESUMEN

Tamoxifen has been a standard therapy for breast cancer, but its use is complicated by serious events, including endometrial cancer and thromboembolism. Tamoxifen therapy beyond the recommended 5 years fails to improve disease outcomes, leaving many patients without a treatment option and susceptible to relapse. While all third-generation aromatase inhibitors have proven to be more effective than tamoxifen in reducing recurrence risk, in a variety of settings, there may be some differences in efficacy. For example, there is evidence that letrozole is the most potent suppressor of estrogen levels, and this may translate to greater clinical efficacy. Indeed, letrozole has been consistent at improving outcomes and is approved in a range of treatment settings, including extended adjuvant therapy, where tamoxifen is not indicated, and more recently, in the early adjuvant setting in the United States and Europe. While other potential long-term complications of aromatase inhibitor therapy will require further study, bone loss appears manageable through bisphosphonate therapy. Results of trials currently under way should determine the optimal use of the aromatase inhibitors in breast cancer therapy.

RESUMEN

PURPOSE: Clinical trials demonstrated the efficacy and safety of intravenous (i.v.) or subcutaneous (s.c.) amifostine for reducing xerostomia and mucositis after radiotherapy or radiochemotherapy for head-and-neck cancer. This randomized, double-blinded, placebo-controlled, phase III study evaluated the efficacy and safety of i.v. amifostine during radiochemotherapy for head-and-neck cancer. METHODS AND MATERIALS: Patients from European and American study centers received i.v. amifostine 300 mg/m2 (n = 67) or placebo (n = 65) before carboplatin 70 mg/m2 and radiotherapy on Days 1 to 5 and 21 to 25, and i.v. amifostine 200 mg/m2 or placebo before radiotherapy on other days. RESULTS: Toxicity incidences were (amifostine, placebo, p value): Grade 2 or higher acute xerostomia (39%, 34%, 0.715), Grade 3 or higher acute mucositis (39%, 22%, 0.055), Grade 2 or higher late xerostomia (37%, 24%, 0.235), and Grade 3 or higher treatment-related adverse events (42%, 20%, 0.008). One-year rates of locoregional failure, progression-free survival, and overall survival were not significantly different between treatments. CONCLUSIONS: The used amifostine doses were not able to reduce the toxicity of simultaneous radiochemotherapy for head-and-neck cancer. The safety of amifostine and the lack of tumor protection were consistent with previous studies.

RESUMEN

BACKGROUND: Monitoring medical decisions at the end of life has become an important issue in many societies. Built on previous European experiences, the survey and project Fin de Vie en France ("End of Life in France," or EOLF) was conducted in 2010 to provide an overview of medical end-of-life decisions in France. OBJECTIVE: To describe the methodology of EOLF and evaluate the effects of design innovations on data quality. METHODS: EOLF used a mixed-mode data collection strategy (paper and Internet) along with follow-up campaigns that employed various contact modes (paper and telephone), all of which were gathered from various institutions (research team, hospital, and medical authorities at the regional level). A telephone nonresponse survey was also used. Through descriptive statistics and multivariate logistic regressions, these innovations were assessed in terms of their effects on the response rate, quality of the sample, and differences between Web-based and paper questionnaires. RESULTS: The participation rate was 40.0% (n=5217). The respondent sample was very close to the sampling frame. The Web-based questionnaires represented only 26.8% of the questionnaires, and the Web-based secured procedure led to limitations in data management. The follow-up campaigns had a strong effect on participation, especially for paper questionnaires. With higher participation rates (63.21% and 63.74%), the telephone follow-up and nonresponse surveys showed that only a very low proportion of physicians refused to participate because of the topic or the absence of financial incentive. A multivariate analysis showed that physicians who answered on the Internet reported less medication to hasten death, and that they more often took no medical decisions in the end-of-life process. CONCLUSIONS: Varying contact modes is a useful strategy. Using a mixed-mode design is interesting, but selection and measurement effects must be studied further in this sensitive field.

RESUMEN

PURPOSE: To assess whether an epirubicin (EPI) -based chemotherapy plus hormonal regimen improves disease-free (DFS) in women older than 65 years, with node-positive, operable breast cancer (BC), relative to tamoxifen (TAM) alone. PATIENTS AND METHODS: A total of 338 patients were randomly assigned after surgery to receive TAM 30 mg/d for 3 years (TAM, n = 164), or EPI 30 mg on days 1, 8, and 15 every 28 days for six cycles plus TAM 30 mg/d for 3 years (EPI-TAM, n = 174). In both arms, patients received radiotherapy, delivered after chemotherapy (CT) in the EPI-TAM group. RESULTS: The 6-year DFS rates were 69.3% with TAM and 72.6% with EPI-TAM (P = .14). The multivariate analysis shows a relative risk of relapse of 1.93 (95% CI, 1.70 to 2.17) with TAM compared with EPI-TAM (P = .005). The 6-year OS, related to disease progression, was 79.1% and 79.8%, respectively (P = .41). Compliance with CT was good: 96.9% of patients received six cycles. The acute toxicity per patient was mild: grade 2 neutropenia in 5.9%, grade 2 anemia in 2.0%, grade 3 nausea or vomiting in 4.6%, and grade 3 alopecia in 7.2%. Five cases (in five patients) of decreased left ventricular ejection fraction occurred after CT: three after adjuvant CT, and two after anthracycline-based CT for relapse. One patient died as a result of dysrhythmia related to carcinomatous lymphangitis. No secondary leukemia occurred. CONCLUSION: This study conducted in node-positive elderly patients demonstrates a significant contribution of a weekly EPI regimen in terms of DFS. Moreover, this regimen is safe for hematologic, nonhematologic, and cardiac toxicities.

RESUMEN

PURPOSE To evaluate long-term cardiac function in patients without disease who had received six cycles of fluorouracil 500 mg/m(2), epirubicin 50 mg/m(2), and cyclophosphamide 500 mg/m(2) (FEC 50) or the same regimen with epirubicin 100 mg/m(2) (FEC 100) as adjuvant chemotherapy for node-positive breast cancer in the French Adjuvant Study Group-05 trial. PATIENTS AND METHODS One hundred fifty patients (FEC 50, n = 65; FEC 100, n = 85) who were without disease and who gave their informed consent were enrolled for long-term cardiac assessment. The assessment included cardiac events occurring after the end of chemotherapy, vital signs, concomitant disease, ECG, isotopic left ventricular ejection fraction (LVEF), and echographic parameters. Abnormal files were blindly reviewed by cardiologists and oncologists. Results The median follow-up time was 102 months. After FEC 100, LVEF was less than 50% in five patients (radioisotopic method), and two patients experienced congestive heart failure (CHF) that was possibly related to treatment. Asymptomatic left ventricular dysfunction (LVD) was experienced in 18 patients after FEC 100 and in one patient after FEC 50. In these patients, treatment causality was probable in eight patients. Two additional years after this assessment, all 18 patients were still asymptomatic. CONCLUSION After more than 8 years of follow-up, the cardiac toxicity observed after adjuvant treatment with FEC 100 comprised two cases of well-controlled CHF and 18 cases of asymptomatic LVD. In the majority of women with primary breast cancer, the benefits of treatment with FEC 100 in terms of disease-free and overall survival outweigh the risks, and cardiac risk factors should be carefully evaluated in patient selection.

RESUMEN

PURPOSE: To analyze overall survival (OS) and update efficacy data for letrozole versus tamoxifen as first-line therapy in postmenopausal women with locally advanced or metastatic breast cancer. PATIENTS AND METHODS: This multicenter phase III trial randomly assigned 916 patients with hormone receptor-positive or unknown tumors letrozole 2.5 mg (n = 458) or tamoxifen 20 mg (n = 458) daily until disease progression. Optional cross-over was permitted at the treating physician's discretion. This report updates efficacy at a median follow-up of 32 months. RESULTS: The superiority of letrozole to tamoxifen was confirmed for time to progression (median, 9.4 v 6.0 months, respectively; P <.0001), time to treatment failure (median, 9 v 5.7 months, respectively; P <.0001), overall objective response rate (32% v 21%, respectively; P =.0002), and overall clinical benefit. Median OS was slightly prolonged for the randomized letrozole arm (34 v 30 months, respectively). Although this difference in OS is not significant, survival was improved in the randomized letrozole arm over the first 2 years of the study. Approximately one half of the patients in each arm crossed over. Total duration of endocrine therapy ("time to chemotherapy") was significantly longer (P =.005) for patients initially on letrozole (median, 16 months) than for patients initially on tamoxifen (median, 9 months). Time to worsening of Karnofsky performance score was significantly delayed with letrozole compared with tamoxifen (P =.001). CONCLUSION: This study documents the superiority of letrozole over tamoxifen in first-line endocrine therapy in postmenopausal women with advanced breast cancer.

RESUMEN

PURPOSE: To evaluate the duration and dose intensity of epirubicin-based regimens in premenopausal patients with lymph node-positive breast cancer. PATIENTS AND METHODS: Between 1986 and 1990, 621 patients with operable breast cancer were randomly assigned to receive fluorouracil (Roche SA, Basel, Switzerland) 500 mg/m2, epirubicin (Pharmacia SA, Milan, Italy) 50 mg/m2, and cyclophosphamide (Asta Medica AG, Frankfurt, Germany) 500 mg/m2 every 21 days (FEC 50) for six cycles (6 FEC 50); FEC 50 for three cycles (3 FEC 50); or the same regimen with epirubicin 75 mg/m2 (FEC 75) for three cycles (3 FEC 75). All patients in the three arms received chest wall irradiation at the end of the third cycle. RESULTS: After a 131-month median follow-up, the 10-year disease-free survival (DFS) was 53.4%, 42.5%, and 43.6% (P =.05) in the three arms, respectively. Pairwise comparisons demonstrate that 6 FEC 50 was superior both to 3 FEC 50 (P =.02) and to 3 FEC 75 (P =.05). The 10-year overall survival (OS) for the 6 FEC 50 arm was 64.3%, for the 3 FEC 50 arm it was 56.6%, and for the 3 FEC 75 arm, it was 59.7% (P =.25), respectively. Pairwise comparisons demonstrate that 6 FEC 50 was more effective than 3 FEC 50 (P =.10). Cox regression analysis demonstrates that OS was significantly better in the 6 FEC 50 than in the 3 FEC 50 arm (P =.046). No severe infections (grade 3 to 4), acute cardiac toxicity, or deaths from toxicity have been observed. Only five patients developed delayed cardiac dysfunctions, and three patients developed acute myeloblastic leukemia. CONCLUSION: After a long-term follow-up in an adjuvant setting, the benefit of six cycles of FEC 50 compared with three cycles, whatever the dose, is highly significant in terms of DFS. As regards OS, the group receiving six cycles of FEC 50 has significantly better results than the group receiving three cycles of FEC 50.

RESUMEN

PURPOSE: To evaluate chronic xerostomia and tumor control 18 and 24 months after initial treatment with amifostine in a randomized controlled trial of patients with head-and-neck cancer; at 12 months after radiotherapy (RT), amifostine had been shown to reduce xerostomia without changing tumor control. METHODS AND MATERIALS: Adults with head-and-neck cancer who underwent once-daily RT for 5-7 weeks (total dose, 50-70 Gy) received either open-label amifostine (200 mg/m2 i.v.) 15-30 min before each fraction of radiation (n = 150) or RT alone (control; n = 153). RESULTS: Amifostine administration was associated with a reduced incidence of Grade > or =2 xerostomia over 2 years of follow-up (p = 0.002), an increase in the proportion of patients with meaningful (>0.1 g) unstimulated saliva production at 24 months (p = 0.011), and reduced mouth dryness scores on a patient benefit questionnaire at 24 months (p < 0.001). Locoregional control rate, progression-free survival, and overall survival were not significantly different between the amifostine group and the control group. CONCLUSIONS: Amifostine administration during head-and-neck RT reduces the severity and duration of xerostomia 2 years after treatment and does not seem to compromise locoregional control rates, progression-free survival, or overall survival.

RESUMEN

The efficacy of the combination bevacizumab-chemotherapy in the first-line treatment of metastatic breast cancer (mBC) was demonstrated in several randomized clinical trials. However, limited safety data is available in daily medical practice. ATHENA is an international phase-IIIb study conducted in 2,251 patients with locally advanced or mBC, treated in first-line with bevacizumab combined with taxanes-based chemotherapy. The primary objective is safety assessment. In France, 365 patients were included. Their median age was 56 years (24-93 years) and ECOG performance status was 0 or 1 in 93.9% of patients. Bevacizumab was essentially combined with a taxanes monotherapy: docetaxel (37.3%) or paclitaxel (28.8%) or taxanes-based combination therapy (9.4%). The most frequent grade superior or equal to 3 adverse event (AE) was neutropenia (34.5%). Grade superior or equal to 3 AEs of special interest related to bevacizumab were arterial and venous thromboembolism (5.1%), high blood pressure (4.2%), proteinuria (2.3%) and hemorrhage (2%). Median time to progression was 9.5 months (95% CI: 8.8-10.4). The safety profile and the efficacy of the combination bevacizumab-taxanes in a population more representative of daily oncology practice in France are comparable to those reported in clinical trials in mBC.

RESUMEN

The use of third-generation aromatase inhibitors (AIs), such as anastrozole and letrozole, as initial adjuvant hormonal therapy in postmenopausal women (PMW) with hormone receptor-positive (HR+) breast cancer offers a significant benefit over tamoxifen for reducing recurrence risk. Clinical studies, including the Arimidex Tamoxifen Alone or in Combination (ATAC) and the Breast International Group (BIG) 1-98 trials, have proven that both anastrozole and letrozole are, respectively, superior to tamoxifen in improving disease-free survival. Although differing in design, objectives, and follow-up time, these trials offer some insight into the comparative clinical efficacy of these two nonsteroidal AIs. In particular, results from BIG 1-98 show that letrozole significantly reduces early distant metastatic (DM) events, which constitute the majority of early recurrence events. Subsequently, there is a beneficial overall survival effect emerging in the trial, whereas survival is unchanged with anastrozole after 100 months of follow-up in ATAC. Significant differences in the potency of these two drugs, vis-à-vis their degree of aromatase inhibition, have been observed in comparative trials and show that letrozole causes a more complete suppression of estrogen levels than does anastrozole. Whether this difference in potency is relevant to reductions in DM events during adjuvant therapy remains unclear. The Femara Anastrozole Clinical Evaluation trial is addressing this issue in a more unequivocal manner by comparing initial adjuvant treatment with anastrozole or letrozole in a population of breast cancer patients at high risk of recurrence: PMW with HR+ disease and axillary lymph node involvement.

RESUMEN

Aromatase inhibitors (AIs) are becoming more widely used than tamoxifen as adjuvant hormonal therapy for postmenopausal women (PMW) with early breast cancer (EBC). It is clear that these drugs offer important efficacy benefits over tamoxifen and differ from tamoxifen in their safety profile. The accepted strategies for adjuvant AI therapy include initial adjuvant treatment following surgery, switching and/or sequencing from prior tamoxifen, and extended adjuvant therapy following the full 5 years of tamoxifen treatment. Among the available AIs, letrozole has been evaluated in large, well-controlled, double-blind clinical trials in the initial adjuvant, extended adjuvant, and more recently, the sequential adjuvant settings. Letrozole is the most potent of the AIs and provides near complete suppression of plasma estrogens in PMW. Letrozole also significantly reduces the occurrence of early distant metastases, the most lethal type of recurrence event, which can lead to improved survival. Clinical comparisons of letrozole with both tamoxifen and placebo have also provided important long-term safety data on the use of AIs as adjuvant therapy in PMW with EBC. The weight of clinical evidence indicates that letrozole is a safe and effective option for adjuvant hormonal therapy across all three AI treatment settings.

RESUMEN

BACKGROUND: Letrozole is safe and effective in postmenopausal women with estrogen receptor-positive early breast cancer, but long-term aromatase inhibitor use may cause bone loss and increase fracture risk. This study evaluated an immediate or delayed strategy of bone protection therapy with zoledronic acid. METHODS: A total of 1065 patients who were receiving adjuvant letrozole were randomized to immediate-start or delayed-start zoledronic acid (4 mg intravenously biannually for 5 years). The delayed group received zoledronic acid if lumbar spine or total hip T-score decreased below -2.0 or when a nontraumatic fracture occurred. The primary endpoint was change in lumbar spine bone mineral density (BMD) at Month 12. Secondary endpoints included changes in total hip BMD, serum bone turnover markers, and safety at Month 12. RESULTS: Lumbar spine BMD increased from baseline in the immediate arm, while it decreased from baseline in delayed-arm patients. At Month 12, the differences between the groups in lumbar spine and total hip BMD were 5.7% (P < .0001; 95% confidence intervals [CI], 5.2% to 6.1%), and 3.6% (P < .0001; 95% CI, 3.3 to 4.0%), respectively. Both regimens were well tolerated with few serious adverse events. Bone pain was higher in the immediate group, as expected, because some patients experienced acute-phase reactions after zoledronic acid infusion. CONCLUSIONS: At 12 months, immediate zoledronic acid therapy prevented bone loss in postmenopausal women who were receiving adjuvant letrozole.
