ABSTRACT: To compare the efficacy of chemoendocrine treatment with that of endocrine treatment (ET) alone for postmenopausal women with highly endocrine responsive breast cancer. In the International Breast Cancer Study Group (IBCSG) Trials VII and 12-93, postmenopausal women with node-positive, estrogen receptor (ER)-positive or ER-negative, operable breast cancer were randomized to receive either chemotherapy or endocrine therapy or combined chemoendocrine treatment. Results were analyzed overall in the cohort of 893 patients with endocrine-responsive disease, and according to prospectively defined categories of ER, age and nodal status. STEPP analyses assessed chemotherapy effect. The median follow-up was 13 years. Adding chemotherapy reduced the relative risk of a disease-free survival event by 19% (P = 0.02) compared with ET alone. STEPP analyses showed little effect of chemotherapy for tumors with high levels of ER expression (P = 0.07), or for the cohort with one positive node (P = 0.03). Chemotherapy significantly improves disease-free survival for postmenopausal women with endocrine-responsive breast cancer, but the magnitude of the effect is substantially attenuated if ER levels are high.Breast cancer research and treatment. 11/2008; 116(3):491-500.

ABSTRACT: Abstract The SBG 2000-1 trial is a randomised study that investigates if dose-tailored adjuvant FEC therapy based on the individual's leukocyte nadir value can improve outcome. The study has included 1535 women with medium and high-risk breast cancer. Patients and methods. After a first standard dosed FEC course (5-fluorouracil 600 mg/m2, epirubicin 60 mg/mg2 and cyclophosphamide 600 mg/m2), patients who did not reach leukopenia grade III or IV were randomised to standard doses (group standard) or doses tailored to achieve grade III leukopenia (group tailored) at courses 2–7. Patients who achieved leukopenia grade III or more after the first course were not randomised but continued on standard doses (group registered). Results. Both planned and actually delivered number of courses (seven) were the same in all three arms. The relative dose intensity was increased by a factor of 1.31 (E 1.22, C 1.43) for patients in the tailored arm compared to the expected on standard dose. Ninety percent of the patients in the tailored arm achieved leukopenia grade III–IV compared with 29% among patients randomised to standard dosed therapy. Dose tailoring was associated with acceptable acute non-haematological toxicity with more total alopecia, nausea, vomiting and fatigue. Conclusion. Dose tailoring according to leukopenia was feasible. It led to an increased dose intensity and was associated with acceptable excess of acute non-haematological toxicity.03/2011; 50(3):329-337.

ABSTRACT: Patient-reported outcomes incorporated in cancer clinical trials, are increasingly hypothesized to be predictors of disease-free survival. Previous research supports health-related quality of life (HRQoL) as an independent predictor of survival in patients with advanced or metastatic breast cancer. In contrast, recent studies provide evidence that baseline HRQoL scores are not associated with increased risk of relapse or survival in women with early-stage breast cancer. One plausible assumption might be that baseline HRQoL scores are limited as predictors of a recurrence of breast cancer several years after the initial diagnosis. In this explorative study, we examined whether changes in HRQoL over time may predict breast cancer recurrence. As a supplement, we investigated whether baseline HRQoL predicted recurrence. The study sample consisted of 141 participants in the International Breast Cancer Study Group adjuvant Trial 12-93 and Trial 14-93, from the Western region of Sweden. HRQoL was assessed, during a 5-year follow up. Poisson regression analysis was used to estimate the hazard function of recurrence depending on time since primary diagnosis and on HRQoL variables. According to the Poisson multivariable regression analysis changes in physical well-being (beta=0.00439, p-value=0.0470), and nausea/vomiting (beta=-0.00612, p-value=0.0136) significantly predicted recurrence. Baseline HRQoL outcomes were not predictors of recurrence. Changes of HRQoL during adjuvant therapy may be associated with recurrence. This explorative finding needs prospective investigation.European journal of oncology nursing : the official journal of European Oncology Nursing Society. 08/2009; 13(5):323-9.

ABSTRACT: International Breast Cancer Study Group (IBCSG) Trial 11-93 is the largest trial evaluating the role of the addition of chemotherapy to ovarian function suppression/ablation (OFS) and tamoxifen in premenopausal patients with endocrine-responsive early breast cancer. IBCSG Trial 11-93 is a randomized trial comparing four cycles of adjuvant chemotherapy (AC: doxorubicin or epirubicin, plus cyclophosphamide) added to OFS and 5 years of tamoxifen versus OFS and tamoxifen without chemotherapy in premenopausal patients with node-positive, endocrine-responsive early breast cancer. There were 174 patients randomized from May 1993 to November 1998. The trial was closed before the target accrual was reached due to low accrual rate. Patients randomized tended to have lower risk node-positive disease and the median age was 45. After 10 years median follow up, there remains no difference between the two randomized treatment groups for disease-free (hazard ratio=1.02 (0.57-1.83); P=0.94) or overall survival (hazard ratio=0.97 (0.44-2.16); P=0.94). This trial, although small, offers no evidence that AC chemotherapy provides additional disease control for premenopausal patients with lower-risk node-positive endocrine-responsive breast cancer who receive adequate adjuvant endocrine therapy. A large trial is needed to determine whether chemotherapy adds benefit to endocrine therapy for this population.Breast cancer research and treatment. 03/2008; 113(1):137-44.
Article: Cost-effectiveness of exemestane versus tamoxifen as adjuvant therapy for early-stage breast cancer after 2-3 years treatment with tamoxifen in Sweden.[show abstract] [hide abstract]
ABSTRACT: Aromatase inhibitors are rapidly becoming the cornerstone of endocrine treatment for advanced disease and are now also used as adjuvant treatment in early-stage disease. The objective of this study was to assess the cost-effectiveness of adjuvant treatment with exemestane versus tamoxifen for early-stage breast cancer after 2-3 years treatment with tamoxifen in Sweden. The results are based on findings in the Intergroup Exemestane Study (IES). IES was a randomized controlled trial in which postmenopausal women who had received 2-3 years of tamoxifen therapy following primary treatment of early-stage breast cancer, were randomized to either continue on tamoxifen therapy or be switched to exemestane therapy. The results showed a disease-free survival hazard ratio of exemestane relative to tamoxifen in IES of 0.69. A Markov state-transition model was developed to simulate consequences after the end of the clinical trial, and to integrate the trial data with external data on mortality, costs and quality of life specific for Swedish women. The cost per QALY gained was about euro 20,000 in the base case analysis without inclusion of consequences of coronary heart disease. Inclusion of these events increased the cost-effectiveness ratio to about euro 31,000. This means that, based on our assumption, sequential exemestane treatment in early breast cancer is a cost-effective option compared with tamoxifen alone, although more long-term data on overall survival and consequences of adverse events would be valuable to increase the validity of the analysis further.Breast cancer research and treatment. 06/2007; 102(3):289-99.
