Background Cardiovascular disease is the primary cause of death among patients with breast cancer. However, the association of cardiovascular-disease risk factors (CVD-RFs) with long-term survival and cardiac events is not well studied. Methods We examined SWOG (formerly the Southwest Oncology Group) breast cancer trials from 1999 to 2011. We identified baseline diabetes, hypertension, hypercholesterolemia, and coronary artery disease by linking trial records to Medicare claims. The primary outcome was overall survival. Patients with both baseline and follow-up claims were examined for cardiac events. Cox regression was used to assess the association between CVD-RFs and outcomes. Results We identified 1,460 participants older than 66 years of age from five trials; 842 were eligible for survival outcomes analysis. At baseline, median age was 70 years, and median follow-up was 6 years. Hypertension (73%) and hypercholesterolemia (57%) were the most prevalent conditions; 87% of patients had one or more CVD-RF. There was no association between any of the individual CVD-RFs and overall survival except for hypercholesterolemia, which was associated with improved overall survival (hazard ratio [HR], 0.73; 95% CI, 0.57 to 0.93; P = .01). With each additional CVD-RF, there was an increased risk of death (HR, 1.23; 95% CI, 1.08 to 1.40; P = .002), worse progression-free survival (HR, 1.12; 95% CI, 1.00 to 1.25; P = .05), and marginally worse cancer-free survival (HR, 1.15; 95% CI, 0.99 to 1.34; P = .07). The relationship between baseline CVD-RFs and cardiac events was analyzed in 736 patients. A strong linear association between the number of CVD-RFs and cardiac event was observed (HR per CVD-RF, 1.41; 95% CI, 1.17 to 1.69; P < .001). Conclusion Among participants in clinical trials, each additional baseline CVD-RF was associated with an increased risk of cardiac events and death. Efforts to improve control of modifiable CVD-RFs are needed, especially among those with multiple risk factors.

513 Background: An Early Breast Cancer Trialists' Collaborative Group (EBCTCG) meta-analysis indicates that adjuvant bisphosphonates increase time to bone recurrence and survival in postmenopausal breast cancer patients, but results of individual trials have been inconclusive. Retrospective analyses of AZURE, a trial of adjuvant zoledronic acid, showed MAF (a transcription factor of the AP-1 family) amplification status predicted bisphosphonate benefit independently of menopause for invasive disease-free survival (IDFS) and overall survival (OS). Validation of MAF amplification status as a potential companion diagnostic for adjuvant bisphosphonates was confirmed using NSABP-B34 specimens. Methods: The randomized, placebo-controlled NSABP B-34 study of women with stage 1-3 breast cancer were assigned to adjuvant systemic therapy plus oral clodronate 1600 mg daily or placebo for 3 years. The primary endpoint was disease-free survival (DFS) with overall survival (OS) as a secondary outcome. MAF amplification was assessed by fluorescence in-situ hybridization on anonymized sections of breast tumor tissue in all patients with tumor samples and performed in a laboratory blind to treatment assignment. Protocol and analysis plans were pre-specified. Disease outcomes were analysed using intention to treat principles. Results: 2496 B-34 patients contributed tumor samples (from 2001-2004), of whom 1883 (75%) were evaluable (947 placebo and 936 clodronate). 1515 (80%) tumors were MAF negative (766 placebo and 749 clodronate) and 368 were MAF positive. At median follow-up of 108 months, MAF was prognostic for DFS, OS and bone-metastasis-free survival in the control group (MAF-positive vs MAF-negative: HRDFS=1·39, 95%CI 1·01-1·92; p=0.045; HROS=1·59, 95%CI 1·08-2·33; p=0.018; HRBM=2·03, 95%CI 1·13-3·68; p=0.016). In patients with MAF-negative tumors, clodronate gave higher DFS and OS than controls at 60 months (HRDFS=0·70, 95%CI 0·51-0·94; p=0.020 and HROS=0·59, 95%CI 0·37-0·93; p=0.024), the latter maintained through follow-up (HROS=0·74, 95%CI 0·54-1.00; p=0.047), but not in patients with MAF-positive tumors - consistent with previous AZURE results. Conclusions: MAF benefit prediction from adjuvant bisphosphonates was confirmed using specimens from 2 randomized clinical trials (AZURE and NSABP-B-34) conducted and analyzed in similar manner using the same validated tests and clinical endpoints. These results are evidence towards introducing MAF testing into clinical practice.

PURPOSE To determine whether perioperative polychemotherapy (PeCT) can significantly prolong the overall survival of women with early-stage breast cancer. METHODS A meta-analysis that used updated individual patient data from all available randomized trials of PeCT, both published and unpublished, was conducted. Data on 6,093 patients (1,124 deaths and 1,912 recurrences) from five clinical trials were available (median follow-up duration, 5.3 years; maximum, 11.3 years). RESULTS No significant effect of PeCT on overall survival was observed. However, patients who received PeCT had a significantly longer disease-free survival (hazards ratio [HR], 0.89; 95% confidence interval [CI], 0.82 to 0.98; P = .02). Time to local recurrence was significantly prolonged in the PeCT arm (HR, 0.68; 95% CI, 0.58 to 0.80; P < .0001). Likewise, there was a borderline significant difference in favor of PeCT in terms of time to distant metastases (HR, 0.90; 95% CI, 0.81 to 1.00; P = .05). Subgroup analyses suggest that node-negative women benefited the most from treatment. CONCLUSION At present, there is no evidence that PeCT is able to prolong overall survival in patients with early-stage breast cancer; however, further follow-up evaluation is required. PeCT significantly prolongs disease-free survival, especially in node-negative women, which emphasizes once more the need for clinical trials in this subgroup.

1508 Background: Mammography is the only imaging modality proven to reduce mortality from breast cancer. Over the past decade, magnetic resonance imaging (MRI) screening of women with increased risk of breast cancer ( > 20% cumulative life time risk) has been recommended. However, there is little evidence that supplemental screening with MRI improves survival. The purpose of this study was to compare survival outcomes of combined screening with MRI and mammography to screening mammography alone in women at increased risk for breast cancer. Methods: A total of 3,002 women at increased risk underwent at least two screening rounds between 2001 and 2005, with at least 5 years of follow-up. 1,534 women had combined screening (MRI and mammography), and 1,468 had screening mammography alone. Cancer detection yield and survival were determined in the two groups. Results: 60 women were diagnosed with breast cancer, 38 patients in the combined screening group and 22 in the mammography-only group. Cancer yield was 24.8 per 1000 (95% CI, 17.6-33.8) combined screening and 15.0 per 1000 (95% CI, 9.4-22.6) mammography-only. No interval cancers occurred in women undergoing combined screening, while 9 interval cancers were found in women undergoing only mammography screening. During a median follow-up of 10.8 years (range, 0.7-15.2), a total of 11 recurrences and 5 deaths (4 breast cancer cause and 1 unknown cause) were found. Of the 11 recurrences, 6 were in the combined screening group and 5 were in the mammography-only group. All deaths were in the mammography-only group. The Kaplan-Meier estimate for disease-free survival showed no statistically significant difference between the two groups ( P = .325). However, patients in the combined screening group had a significantly better overall survival compared with patients in the mammography-only group ( P = .002). Conclusions: Combined screening with MRI and mammography in women with increased risk of breast cancer resulted in not only a higher cancer detection yield but also better overall survival.

ObjectiveThe aim of the study was to report on the oncologic outcome of the disease spread to celiac lymph nodes (CLNs) in advanced-stage ovarian cancer patients.MethodsAll patients who had CLN resection as part of their cytoreductive surgery for epithelial ovarian, fallopian, or primary peritoneal cancer were identified. Patient demographic data with particular emphasis on operative records to detail the extent and distribution of the disease spread, lymphadenectomy procedures, pathologic data, and follow-up data were included.ResultsThe median follow-up was 26.3 months. The median overall survival values in the group with positive CLNs and in the group with negative CLNs were 26.9 months and 40.04 months, respectively. The median progression-free survival values in the group with metastatic CLNs and in the group with negative CLNs were 8.8 months and 20.24 months, respectively (P = 0.053). Positive CLNs were associated with progression during or within 6 months after the completion of chemotherapy (P = 0.0044). Tumor burden and extensive disease distribution were significantly associated with poor progression-free survival, short-term progression, and overall survival. In multivariate analysis, only the CLN status was independently associated with short-term progression.ConclusionsDisease in the CLN is a marker of disease severity, which is associated to a high-risk group of patients with presumed adverse tumor biology, increased risk of lymph node progression, and worst oncologic outcome.

Limited data are available regarding the association of major dietary patterns and risk of cardiovascular disease (CVD) in Middle Eastern countries. We aimed to evaluate the association of major dietary patterns, using factor analysis, with the risk of CVD. Participants without CVD (n = 2284) were recruited from the Tehran Lipid and Glucose Study and were followed for a mean of 4.7 years. Dietary intake of participants was assessed at baseline (2006–2008); biochemical variables were evaluated at baseline and follow-up examination. Multivariate Cox proportional hazard regression models, adjusted for potential confounders, were used to estimate risk of CVD across tertiles of dietary pattern scores. Linear regression models were used to indicate association of dietary pattern scores with changes of CVD risk factors over the study period. Two major dietary patterns, Western and traditional, were identified. During a mean 4.7 ± 1.4 years of follow-up, 57 participants experienced CVD-related events. In the fully adjusted model, we observed an increased risk of CVD-related events in the highest compared to the lowest tertile category of Western dietary pattern score (HR = 2.07, 95% CI = 1.03–4.18, P for trend = 0.01). Traditional dietary pattern was not associated with incidence of CVD or CVD risk factors. A significant association was observed between the Western dietary pattern and changes in serum insulin (β = 5.88, 95% CI = 0.34–11.4). Our findings confirm that the Western dietary pattern, characterized by higher loads of processed meats, salty snacks, sweets, and soft drinks, is a dietary risk factor for CVD in the Iranian population.

PURPOSE: We conducted a phase II pilot study of dose-intensive adjuvant chemotherapy with doxorubicin followed sequentially by high-dose cyclophosphamide to determine the safety and feasibility of this dose-dense treatment and to estimate the disease-free and overall survival in breast cancer patients with four or more involved axillary lymph nodes. PATIENTS AND METHODS: Seventy-three patients received adjuvant treatment with four cycles of doxorubicin 75 mg/m2 as an intravenous bolus every 21 days, followed by three cycles of cyclophosphamide 3,000 mg/m2 every 14 days with granulocyte colony-stimulating factor support. RESULTS: Seventy-one patients were assessable, and all but two completed all planned chemotherapy. There was no treatment-related mortality. The most common toxicity was neutropenic fever, which occurred in 39% of patients. Median disease-free survival is 66 months (95% confidence interval, 34 to 98 months), and median overall survival has not yet been reached. At 5 years of follow-up, the disease-free survival is 51.7%, and overall survival is 60.0%. There is no long-term treatment-related toxicity, and no cases of acute myelogenous leukemia or myelodysplastic syndrome have been observed. CONCLUSION: Our pilot study of doxorubicin followed by cyclophosphamide demonstrates the safety and feasibility of the sequential dose-dense plan. Long-term follow-up, although noncomparative, is promising. However, this regimen is associated with a higher incidence of toxicity (and also higher costs) than the standard dose and schedule of doxorubicin and cyclophosphamide, and therefore it should not be used as conventional therapy in the absence of demonstrated improvement of outcome. Randomized trials testing the dose-dense approach have been completed but not yet reported. Because the sequential plan can decrease overlapping toxicities, it is an appropriate platform for the addition of newer active agents, such as taxanes or monoclonal antibodies.

Hypertensive disorders of pregnancy (HDP), such as gestational hypertension and pre-eclampsia, affect up to 10% of all pregnancies. These women have on average a twofold higher risk to develop cardiovascular disease (CVD) later in life as compared with women with normotensive pregnancies. This increased risk might result from an underlying predisposition to CVD, HDP itself or a combination of both. After pregnancy women with HDP show an increased risk of classical cardiovascular risk factors including chronic hypertension, renal dysfunction, dyslipidemia, diabetes and subclinical atherosclerosis. The prevalence and onset of cardiovascular risk factors depends on the severity of the HDP and the coexistence of other pregnancy complications. At present, guidelines addressing postpartum cardiovascular risk assessment for women with HDP show a wide variation in their recommendations. This makes cardiovascular follow-up of women with a previous HDP confusing and non-coherent. Some guidelines advise to initiate cardiovascular follow-up (blood pressure, weight and lifestyle assessment) 6–8 weeks after pregnancy, whereas others recommend to start 6–12 months after pregnancy. Concurrent blood pressure monitoring, lipid and glucose assessment is recommended to be repeated annually to every 5 years until the age of 50 years when women will qualify for cardiovascular risk assessment according to all international cardiovascular prevention guidelines.

Abstract Sixty-four patients (pts) with chemotherapy-refractory CLL who were ineligible for ablative allogeneic HCT due to age and/or comorbidities were given nonablative-HCT from related (n=44) or unrelated donors (n=20) between 1997-2003 (Table). Median pt age was 56 (range 44–69) years, interval from diagnosis to HCT was 4.4 (3–25) years, and number of prior regimens was 4 (range 1–12). Sixty-one pts were refractory to at least 1 regimen, 56 to fludarabine (FLU), 19 to alkylating agents, 14 to rituxumab and 4 to CAMPATH, and 2 had failed autologous HCT. Twenty-three pts (36%) had disease responsive to last chemotherapy [28% partial (PR) and 8% complete remission (CR)] while 34 were nonresponsive and 7 had untested relapse. Conditioning for HCT consisted of 2 Gy TBI alone (n=11) or combined with FLU (n=53), 90 mg/m2. Postgrafting immunosuppression consisted of mycophenolate mofetil and cyclosporine. Pts received G-CSF mobilized peripheral blood mononuclear cells. After HCT, pts became neutropenic for a median of 11 days. Forty-four percent of pts had thrombocytopenia (&lt;20,000 cells/ul). Three pts had graft rejection; 1 died with aplasia and 2 are alive with disease relapse. Incidences of grades II, III, and IV acute GVHD were 39%, 14%, and 2% respectively, and chronic GVHD was 50% at 2-years. With median follow up of 24 (range 2.8–62.8) months, the overall response rate was 67% (50% in CR). URD-pts had significantly higher CR rate than MRD-pts. All 11 responding patients tested had molecular eradication of their disease. Overall, 39 patients are alive; 25 in CR, 5 in PR, 2 with stable disease, and 7 with relapse/progression. Twenty-five pts died, 10 from progression, 10 from infections ± GVHD, 2 from cardiac causes, 1 from metastatic lung cancer, 1 from cerebral stroke and 1 from rejection and aplasia. Estimated 2-year rates of non-relapse mortality, disease free survival, and overall survival were 22%, 52%, and 60% respectively. In multivariate analysis, high pretransplant comorbidity scores predicted higher non-relapse mortality and worse survival while bulky lymphadenopathy predicted increased risk of progression. CLL appears susceptible to graft-versus-leukemia effects particularly after URD grafts and nonablative-HCT should be explored in phase II trials in pts with FLU-refractory CLL.

Abstract Introduction Despite widespread use of all-trans retinoic acid (ATRA) in treatment of Acute Promyelocytic Leukemia (APL), recent studies in the US1 and Sweden2 have reported continuing high rates of early death. Patient age has appeared to be an important factor affecting outcomes. We studied the incidence and outcomes in the Canadian APL patients to determine which patients may be at higher risk, and to analyze the success of current management. Methods We used data from the Canadian Cancer Registry, which included all patients diagnosed between 1993-2007. We obtained incidence, Early Death (ED) (death within 30 days of diagnosis), and 1 and 5-year overall survival (OS). This was stratified by age, sex, and time period of diagnosis. Detailed information was obtained on a subset of patients managed at five Canadian leukemia referral centres from 1999 to 2010. Results There were 399 cases of APL diagnosed in Canada between 1993-2007.This accounted for 3.01% of Acute Myeloid Leukemia cases. Incidence (age-standardized to the 1991 Canadian census population) was 0.083/100000. The incidence was greater in the population aged 50 and over, with an incidence rate ratio (IRR) of 2.192 (95% C.I.1.80 - 2.67, p<0.001). ED was 21.8% overall, with a rate over three times higher in older patients as compared to younger patients. The ED rate was 10.6% in younger (<50 years) patients and 35.5% in older (≥50 years) patients. One-year overall survival was 84.1% in younger patients as compared to 52.3% in older adults. The rate of death at one year is nearly three times higher in the older patients. Five-year survival was 54.6%; this was 73.3% in the younger patients (<50), and 29.1% in the older group (≥50 years). There were 131 patients in the leukemia referral centre cohort, who predominantly received tretinoin (ATRA) based therapy. In this population, ED was 14.6%. Two-year OS was 76.5% (95% C.I. 68%-83%). Age over 60 predicted an inferior outcome at 2-years with a hazard ratio of 4.051 (95% CI 1.17-7.57). Conclusions To our knowledge, this is the largest nationwide epidemiologic study of APL. Despite widespread use of ATRA in Canada and low rates of ED reported in clinical trials (often 3-8%), we found that the real survival outcomes of APL were worse than anticipated. However they were similar to those reported recently from other developed counties1,2. The outcomes were much poorer for the older patients with APL. This included a higher rate of early death as well as poorer rates of survival at one, two and five year follow-up times. The ED rates of patients <50 more closely matched rates reported in clinical trials. We compared the survival outcomes of the entire population with APL to a sample of only patients treated at specialized referral centres. Despite receiving care in a specialized tertiary centre, the survival of older patients remained significantly poorer than the younger patients. The incidence of APL was also double in the older population as compared to the younger population. Overall the age-standardized incidence was lower in Canada than has been reported in other countries1,2. This emphasizes that, although APL is a type of AML that does affect younger patients, there is a large and important impact of this disease on older patients. Recent studies in the US and Sweden have also reported higher rates of APL in older populations and poorer rates of survival at various follow up times. Overall the patients with high-risk Sanz scores had the worst survival outcomes. The survival at most time points was slightly higher for patients scored as intermediate-risk compared to those who were in the low-risk category. When arsenic becomes widely available as a first line therapy it will be important to continue population-based analysis to see how this affects outcomes and whether the outcomes are difference in difference age groups or populations.
