Abstract
BACKGROUND Obesity has been associated with an adverse prognosis and reduced efficacy of endocrine therapy in patients with hormone receptor-positive (HR+) breast cancer (BC). This study determines the prognostic and predictive effect of body mass index (BMI) on the disease-free survival (DFS) of postmenopausal HR+ BC patients. METHODS Patients were identified from the DATA study (NCT00301457), a randomized controlled trial evaluating the efficacy of 6 vs 3 years of anastrozole after 2 to 3 years of adjuvant tamoxifen in postmenopausal women with HR+ BC. Patients were classified as normal weight (BMI: 18.5-24.9 kg/m2), overweight (25.0-29.9 kg/m2), or obese (≥30.0 kg/m2). The primary endpoint was DFS, evaluated from randomization (prognostic analyses) or 3 years after randomization onwards (predictive analyses; aDFS) using multivariable Cox regression analyses. P-values were 2-sided. RESULTS This study included 678 normal weight, 712 overweight, and 391 obese patients. After a median follow-up of 13.1 years, overweight and obesity were identified as negative prognostic factors for DFS (hazard ratio (HR) = 1.16; 95% confidence interval (CI) = 0.97 to 1.38 and HR = 1.26; 95% CI = 1.03 to 1.54, respectively). The adverse prognostic effect of BMI was observed in women aged younger than 60 years, but not in women aged 60 years or older (P-interaction = .009). The effect of extended anastrozole on aDFS was similar in normal weight (HR = 1.00; 95% CI = 0.74 to 1.35), overweight (HR = 0.74; 95% CI = 0.56 to 0.98), and obese patients (HR = 0.97; 95% CI = 0.69 to 1.36) (P-interaction = .24). CONCLUSION In this study among 1781 HR+ BC patients, overweight and obesity were adverse prognostic factors for DFS. BMI did not impact the efficacy of extended anastrozole.

Abstract
Background The DATA study evaluated the use of two different durations of anastrozole in patients with hormone receptor-positive breast cancer who were disease-free after 2–3 years of tamoxifen. We hereby present the follow-up analysis, which was performed after all patients reached a minimum follow-up of 10 years beyond treatment divergence. Methods The open-label, randomised, phase 3 DATA study was performed in 79 hospitals in the Netherlands (ClinicalTrials.gov, number NCT00301457). Postmenopausal women with hormone receptor-positive breast cancer who were disease-free after 2–3 years of adjuvant tamoxifen treatment were assigned to either 3 or 6 years of anastrozole (1 mg orally once a day). Randomisation (1:1) was stratified by hormone receptor status, nodal status, HER2 status, and prior tamoxifen duration. The primary outcome was adapted disease-free survival, defined as disease-free survival from 3 years after randomisation onwards. Adapted overall survival was assessed as a secondary outcome. Analyses were performed according to the intention-to-treat design. Findings Between June 28, 2006, and August 10, 2009, 1912 patients were randomly assigned to 3 years (n = 955) or 6 years (n = 957) of anastrozole. Of these, 1660 patients were eligible and disease-free at 3 years after randomisation. The 10-year adapted disease-free survival was 69.2% (95% CI 55.8–72.3) in the 6-year group (n = 827) and 66.0% (95% CI 62.5–69.2) in the 3-year group (n = 833) (hazard ratio (HR) 0.86; 95% CI 0.72–1.01; p = 0.073). The 10-year adapted overall survival was 80.9% (95% CI 77.9–83.5) in the 6-year group and 79.2% (95% CI 76.2–81.9) in the 3-year group (HR 0.93; 95% CI 0.75–1.16; p = 0.53). Interpretation Extended aromatase inhibition beyond 5 years of sequential endocrine therapy did not improve the adapted disease-free survival and adapted overall survival of postmenopausal women with hormone receptor-positive breast cancer.

Abstract
Short-term fasting protects tumor-bearing mice against the toxic effects of chemotherapy while enhancing therapeutic efficacy. We randomized 131 patients with HER2-negative stage II/III breast cancer, without diabetes and a BMI over 18 kg m-2, to receive either a fasting mimicking diet (FMD) or their regular diet for 3 days prior to and during neoadjuvant chemotherapy. Here we show that there was no difference in toxicity between both groups, despite the fact that dexamethasone was omitted in the FMD group. A radiologically complete or partial response occurs more often in patients using the FMD (OR 3.168, P = 0.039). Moreover, per-protocol analysis reveals that the Miller&Payne 4/5 pathological response, indicating 90-100% tumor-cell loss, is more likely to occur in patients using the FMD (OR 4.109, P = 0.016). Also, the FMD significantly curtails chemotherapy-induced DNA damage in T-lymphocytes. These positive findings encourage further exploration of the benefits of fasting/FMD in cancer therapy. Trial number: NCT02126449.

Abstract
Background: Previously, we showed that reintroduction of the same (first-line) chemotherapy at progression could only partially make up for the loss in efficacy as compared to continuously delivered first-line chemotherapy. Here, we report the probability of starting second-line study chemotherapy in the Stop&Go trial, and the progression-free survival (PFS) and overall survival (OS) of patients who received both the first- and second-line treatment in an intermittent versus continuous schedule.Methods: First-line chemotherapy comprised paclitaxel plus bevacizumab, second-line capecitabine or non-pegylated liposomal doxorubicin, given per treatment line as two times four cycles (intermittent) or as eight consecutive cycles (continuous).Results: Of the 420 patients who started first-line treatment within the Stop&Go trial (210:210), a total of 270 patients continued on second-line study treatment (64% of all), which consisted of capecitabine in 201 patients and of non-pegylated liposomal doxorubicin in 69 patients, evenly distributed between the treatment arms. Median PFS was 3.7 versus 5.0 months (HR 1.07; 95% CI: 0.82-1.38) and median OS 10.9 versus 12.4 months (HR 1.27; 95% CI: 0.98-1.66) for intermittent versus continuous second-line chemotherapy. Second-line PFS was positively influenced by prior hormonal therapy for metastatic disease and longer first-line PFS duration, while triple-negative tumor status had a negative influence. Patients with a shorter time to progression (TTP) in first-line (≤10 months) had a higher probability of starting second-line treatment if they received intermittent compared to continuous chemotherapy (OR 1.97; 95% CI: 1.02-3.80).Conclusion: We recommend continuous scheduling of both the first- and second-line chemotherapy for advanced breast cancer.

Abstract
Purpose The phase III DATA study compared 6 and 3 years of adjuvant anastrozole following 2–3 years of tamoxifen in postmenopausal breast cancer patients. This pre-planned side-study assessed the relationship between a reduced bone mineral density (BMD) and distant recurrence-free survival (DRFS), and evaluated the effect of bisphosphonates on DRFS. Methods We selected all patients with a BMD measurement within 3 years after randomisation (landmark) without any DRFS events. Kaplan–Meier methods and Cox proportional hazards models were used for analyses. Results Of 1860 eligible patients, 1142 had a DEXA scan before the landmark. The BMD was normal in 436 (38.2%) and showed osteopenia in 565 (49.5%) and osteoporosis in 141 (12.3%) patients. After a median follow-up of 5.0 years from the landmark, neither osteopenia nor osteoporosis (compared with normal BMD) were associated with DRFS in both the 6-year [osteopenia HR 0.82 (95% CI 0.45–1.49), osteoporosis HR 1.10 (95% CI 0.26–4.67)] and the 3-year arm [osteopenia HR 0.75 (95% CI 0.40–1.42), osteoporosis HR 1.86 (95% CI 0.43–8.01)]. Moreover, bisphosphonate use did not impact DRFS. Conclusion No association was observed between a reduced BMD and DRFS. Neither did we observe an impact of bisphosphonates on DRFS.

Abstract
The phase III DATA study investigates the efficacy of adjuvant anastrozole (6 vs. 3 year) in postmenopausal women with breast cancer previously treated with 2–3 years of tamoxifen. This planned side‐study assessed patterns of care regarding detection and treatment of osteopenia/osteoporosis, and trends in bone mineral density (BMD) during and after therapy. We registered all BMD measurements and bisphosphonate‐use. Time to osteopenia/osteoporosis was analysed by Kaplan Meier methodology. For the trend in T‐scores we used linear mixed models with random patients effects. Of 1860 eligible DATA patients, 910 (48.9%) had a baseline BMD measurement. Among patients with a normal baseline BMD (n = 417), osteopenia was observed in 53.5% and 55.4% in the 6‐ and 3‐year group respectively (p = 0.18), during follow‐up. Only two patients (3‐year group) developed osteoporosis. Of the patients with osteopenia at baseline (n = 408), 24.4% and 20.4% developed osteoporosis respectively (p = 0.89). Three years after randomisation 18.3% and 18.2% used bisphosphonates in the 6‐ and 3‐year groups respectively and 6 years after randomisation this was 23.7% and 20.9% respectively (p = 0.90) of which the majority used oral bisphosphonates. The yearly mean BMD‐change during anastrozole in the lumbar spine showed a T‐score decline of 0.075. After bisphosphonate addition the decline became less prominent (0.047 (p < 0.001)) and after anastrozole cessation, while continuing bisphosphonates, the mean BMD yearly increased (0.047 (p < 0.001)). In conclusion, extended anastrozole therapy was not associated with a higher incidence of osteoporosis. Anastrozole‐use was associated with a BMD decrease; however, the decline was modest and partially reversible after anastrozole cessation. What's new? Loss of bone mineral density (BMD) is a side effect of aromatase inhibitor treatment, a class of drugs that stops estrogen production in postmenopausal women with breast cancer. Here the authors examined BMD loss during and after extended adjuvant endocrine therapy, following a 2‐3 year treatment with tamoxifen, subsequent aromatase inhibitor treatment was associated with BMD decrease, but the decline was modest and partially reversible after treatment cessation. The authors concluded that extended endocrine therapy was not associated with a higher incidence of osteoporosis.

Abstract
Background Aromatase inhibitors (AIs) are given as adjuvant therapy for hormone receptor-positive breast cancer in postmenopausal women, also to those with chemotherapy-induced ovarian function failure. The current analysis reports on endocrine data of patients with chemotherapy-induced ovarian function failure who were included in the phase III DATA study assessing different durations of adjuvant anastrozole after tamoxifen. Methods We identified all patients with chemotherapy-induced ovarian function failure. Women who underwent a bilateral ovariectomy or used luteinizing hormone-releasing hormone agonists before random assignment were excluded. Plasma estradiol and follicle-stimulating hormone levels were monitored until 30 months after random assignment at local laboratories. We aimed to determine the ovarian function recovery (OFR) rate during AI use by the cumulative incidence competing risk method and analyzed the trend of estradiol levels during AI use by a nested case-control approach in which a subset of control subjects were compared with the OFR patients excluding the value at OFR diagnosis. Results The 329 eligible patients had a median age of 50.0 years (range = 45-57 years) at random assignment. Thirty-nine patients developed OFR, corresponding with a 30-month recovery rate of 12.4%. Of these, 11 (28.2%) were age 50 years or older at AI initiation. The estradiol level decreased statistically significantly by 37.8% (95% CI = 27.4% to 46.7%) over the initial 30 months of AI treatment in both groups. However, the estradiol levels in the women who experienced OFR remained statistically significantly higher (difference = 20.6%, 95% CI = 2.0% to 42.7%) prior to OFR diagnosis compared with those who did not experience OFR. Conclusions The risk of OFR during AI treatment in breast cancer patients with chemotherapy-induced ovarian function failure is relevant, even beyond 45 years. Furthermore, women experiencing OFR had statistically significant higher estradiol levels during AI treatment (before OFR) than those without, with potential consequences regarding efficacy.

Abstract
The DATA study (NCT00301457) compared 6 and 3 years of anastrozole in postmenopausal women with hormone receptor-positive early breast cancer after 2-3 years of tamoxifen. Patients with chemotherapy-induced ovarian function failure (CIOFF) were also eligible, but could be at risk of ovarian function recovery (OFR). The current analysis compared the survival of women with CIOFF with definitely postmenopausal women and examined the influence of OFR on survival. Therefore, we selected patients from the DATA study aged 45-57 years at randomization who had received (neo)adjuvant chemotherapy. They were classified by reversibility of postmenopausal status: possibly reversible in case of CIOFF (n = 395) versus definitely postmenopausal (n = 261). The former were monitored by E2 measurements for OFR. The occurrence of OFR was incorporated as a time-dependent covariate in a Cox-regression model for calculating the hazard ratio (HR). We used the landmark method to calculate residual 5-year survival rates. When comparing CIOFF women with definitely postmenopausal women, the survival was not different. Among CIOFF women with available E2 follow-up values (n = 329), experiencing OFR (n = 39) had an unfavorable impact on distant recurrence-free survival (HR 2.27 [95% confidence interval [CI] 0.98-5.25; p = 0.05] and overall survival (HR 2.61 [95% CI 1.11-6.13; p = 0.03]). After adjusting for tumor features, the HRs became 2.11 (95% CI 0.89-5.02; p = 0.09) and 2.24 (95% CI 0.92-5.45; p = 0.07), respectively. The residual 5-year rate for distant recurrence-free survival was 76.9% for women with OFR and 92.1% for women without OFR, and for 5-year overall survival 80.8% and 94.4%, respectively. Women with CIOFF receiving anastrozole may be at increased risk of disease recurrence if experiencing OFR.

Abstract
523 Background: The DATA study compared 6 and 3 years of anastrozole therapy in postmenopausal women with hormone-receptor positive early breast cancer previously treated with 2-3 years tamoxifen (oral presentation SABCS 2016 #S01-03). The study included postmenopausal women, allowing those with chemotherapy-induced ovarian function failure (CIOFF). However, these may be at risk of ovarian function recovery (OFR). The current analysis compared the survival of women with CIOFF with definite postmenopausal women and examined the influence of OFR on survival. Methods: We selected patients from the DATA study aged 45-57 years at randomization who had received (neo-)adjuvant chemotherapy. They were classified by menopausal status at randomization (definite postmenopausal before chemotherapy or by ovariectomy, versus CIOFF). The latter were monitored by estradiol measurements for OFR during anastrozole. Endpoints: Disease-free Survival (DFS), Distant Recurrence-free Survival (DRFS), and Overall Survival (OS), corrected for tumor size, nodal status, grade, and hormone-receptor status. We used the landmark method to calculate residual 5-year survival rates. Results: In total, 261 patients were definite postmenopausal and 395 had CIOFF, of whom 39 experienced OFR while 290 did not (66 were excluded from the landmark analysis because follow-up estradiol levels were lacking). When comparing the CIOFF with the definite postmenopausal women, the 5-year survival rates were not significantly different. Within the group with CIOFF, experiencing OFR was associated with a trend for worse outcome (DFS-event HR 1.33 (95% CI 0.61-2.90), P=0.48; DRFS-event HR 2.11 (95% CI 0.89-5.02), P=0.09; and OS-event HR 2.24 (95% CI 0.92-5.45), P=0.07). Patients who experienced OFR in the first year had a residual 5-year rate for DFS of 73.1% compared with 87.4% in those who did not. For DRFS these rates were 76.9% vs. 92.1%, and for OS 80.8% vs. 94.4% respectively. Conclusions: These results suggest that women with CIOFF undergoing anastrozole treatment may be at increased risk of disease recurrence if experiencing OFR despite close monitoring of estradiol levels and adjusting endocrine treatment.

Abstract
BACKGROUND To explore the role of bevacizumab and a chemotherapy-free approach, the authors evaluated the combination of bevacizumab, trastuzumab, and paclitaxel (HAT) and the regimen of trastuzumab and bevacizumab (HA) with the addition of paclitaxel after progression (HA-HAT) as first-line treatment for patients with human epidermal growth factor receptor 2 (HER2)-positive metastatic breast cancer. METHODS In a noncomparative phase 2 trial, patients were randomized between HAT and HA-HAT. The primary endpoint was the progression-free rate at 1 year (1-year PFR). In the HA-HAT group, progression-free survival (PFS) was separately established for HA (PFS1) and HAT (PFS2). RESULTS Eighty-four patients received HAT (n = 39) or HA-HAT (n = 45). The 1-year PFR was 74.4% (95% confidence interval [CI], 61.8%-89.4%) and 62.2% (95% CI, 49.6%-89.4%) in the HAT and HA-HAT arms, respectively. The median PFS was 19.8 months (95% CI, 14.9-25.6 months) in the HAT arm and 19.6 months (95% CI, 12.0-32.0 months) in the HA-HAT arm. In the HA-HAT arm, the median PFS1 was 10.4 months (95% CI, 6.2-15.0 months), and the median PFS2 was 8.2 months (95% CI, 7.0-12.6 months). The number and severity of adverse events were comparable between the arms. CONCLUSIONS Both HAT and HA-HAT have promising activity in patients with HER2-positive metastatic breast cancer. In particular, starting with only targeted agents and delaying chemotherapy is worth further exploration. Cancer 2016;122:2961-2970. © 2016 American Cancer Society.

Abstract
BACKGROUND According to surveys, many patients with advanced cancer wish to receive survival information. OBJECTIVE This study investigated information preferences by offering patients a decision aid (DA) with information on expected survival for two treatment options: supportive care with or without second-line palliative chemotherapy. Predictors of accepting survival information were explored. DESIGN Eligible patients in this multicentre prospective study were offered second-line chemotherapy for advanced breast or colorectal cancer. A nurse presented a DA on second-line treatment and asked patients whether they desired information on (i) adverse events, (ii) tumour response and (iii) survival. Data on 50 clinical and psychosocial patient characteristics were collected from inclusion forms and patient questionnaires. RESULTS Seventy-seven patients received a DA; median age 62 years (range 32-80), 61% female, 77% colorectal cancer. Fifty-seven patients (74%; 95% CI 64-84) desired survival information. Four psychosocial characteristics (e.g. deliberative decision style) independently predicted information desire. However, the use of these characteristics to predict information desire hardly outperformed a simple prediction rule. CONCLUSIONS Many patients desired information on expected survival when deciding about second-line treatment. However, our exploratory analysis indicated that patients desiring this information could not be identified based on their clinical or psychosocial characteristics. These findings can help encourage candid discussions about expected survival. Health professionals should be careful not to make implicit assumptions of information desire based on patient characteristics, but to explicitly ask patients if survival information is desired, and act accordingly.

Abstract
1072 Background: In the randomized phase II ATX trial, pts with HER2-negative LR/MBC were treated with first-line AT or ATX. We determined the prognostic value for outcome of VEGF-A, ANG2 and sTIE2 measured at baseline on cycle 1 day 1 (C1D1) and after cycle 1 (C2D1). Methods: 312 pts were randomized in 1:1 ratio to AT (T 90 mg/m2 on d1, 8, 15 and A 10 mg/kg on d1, 15 q4w x 6 cycles, followed by A 15 mg/kg on d1 q3w for next cycles) or ATX (T 90 mg/m2 on d1, 8, A 15 mg/kg on d1 and X 825 mg/m2bid on d1–14 q3w x 8 cycles, followed by the same dose of A and X q3w for next cycles). The primary endpoint was progression-free survival (PFS). Secondary endpoints were objective response rate (ORR), response duration (RD), overall survival (OS) and safety. Plasma proteins on C1D1 (N = 173) and on C2D1 (N = 142) were measured by ELISA. The association of protein levels (continuous variable) with PFS and OS was evaluated by Cox proportional hazards model and Martingale residual plot. Results: At a median follow-up of 39 months (mo), there were 292 PFS events and 242 deaths. ATX significantly improved PFS as compared to AT (median 11 vs. 8.4 mo, stratified HR = 0.52; 95% CI, 0.41 – 0.67; P < .001). The confirmed ORR in measurable disease (N = 268) was 67% in ATX vs. 50% in AT. Median RD was 6.4 mo (95% CI, 6.1 – 8.3) in ATX v 5.4 mo (95% CI, 5.1 – 6.0) in AT. Median OS was 24.1 mo in ATX vs. 23.1 mo in AT (P= .44). The aselected ‘biomarker’ cohort (N = 173) and overall trial cohort had similar baseline characteristics. ANG2 on C1D1 moderately correlated with sTIE2 on C1D1 (Pearson’s r = .44, P < .001). High ANG2 on C1D1 was significantly associated with poor OS (HR = 1.6; 95% CI, 1.1 – 2.3; P = .01), but not with poor PFS (HR = 1.3; 95% CI, 1.0 – 1.3; P = .07). ANG2 on C2D1 was not significantly associated with OS (HR = 1.55; 95% CI, 0.99 – 2.4; P = .057) or with PFS (P= .6). sTIE2 and VEGF-A were not associated with outcome. All pts had very low levels of free VEGF-A on C2D1 (median 8 pg/ml). Conclusions: In HER2-negative LR/MBC, ATX is more effective (PFS, ORR and RD) than AT. A very high plasma level of ANG2 at baseline indicates a high risk for poor survival. Clinical trial information: NTR1348.
