BackgroundMetastatic breast cancer (MBC) is a highly heterogeneous disease and bone is one of the most common metastatic sites. This retrospective study was conducted to investigate the clinical features, prognostic factors and benefits of surgery of breast cancer patients with initial bone metastases.MethodsFrom 2010 to 2015, 6,860 breast cancer patients diagnosed with initial bone metastasis were analyzed from Surveillance, Epidemiology, and End Results (SEER) database. Univariate and Multivariable analysis were used to identify prognostic factors. A nomogram was performed based on the factors selected from cox regression result. Survival curves were plotted according to different subtypes, metastatic burdens and risk groups differentiated by nomogram.ResultsHormone receptor (HR) positive/human epidermal growth factor receptor 2 (HER2) positive patients showed the best outcome compared to other subtypes. Patients of younger age (<60 years old), white race, lower grade, lower T stage (<=T2), not combining visceral metastasis tended to have better outcome. About 37% (2,249) patients received surgery of primary tumor. Patients of all subtypes could benefit from surgery. Patients of bone-only metastases (BOM), bone and liver metastases, bone and lung metastases also showed superior survival time if surgery was performed. However, patients of bone and brain metastasis could not benefit from surgery (p = 0.05). The C-index of nomogram was 0.66. Cutoff values of nomogram point were identified as 87 and 157 points, which divided all patients into low-, intermediate- and high-risk groups. Patients of all groups showed better overall survival when receiving surgery.ConclusionOur study has provided population-based prognostic analysis in patients with initial bone metastatic breast cancer and constructed a predicting nomogram with good accuracy. The finding of potential benefit of surgery to overall survival will cast some lights on the treatment tactics of this group of patients.

11092 Background: Approximately half of HER2-positive breast cancer patients will respond to first-line trastuzumab-containing therapy. However, in those patients with an initial trastuzumab response, most will progress within a year with acquired resistance. Since trastuzumab treatment is also now used in the HER2-positive adjuvant breast cancer setting, trastuzumab resistance will continue to be a vexing clinical problem, and better predictive and prognostic biomarkers are urgently needed. Methods: Serum HER2, tissue inhibitor of metalloproteinase-1 (TIMP-1), urokinase-type plasminogen activator (uPA), CA9, VEGF-165, and endoglin were measured using ELISA assays in 66 metastatic breast cancer patients before starting first-line trastuzumab-containing therapy. The HER2, TIMP-1, uPA, CA9, and VEGF-165 ELISAs were from Oncogene Science/Siemens Healthcare Diagnostics, Cambridge, MA; and the endoglin ELISA was from R&D Systems, Minneapolis, MN. Progression-free (PFS) and overall survival (OS) were analyzed using the Kaplan-Meier method and Cox modeling with continuous pretreatment serum biomarker variables. Results: Pretreatment serum HER2 (p= 0.005), TIMP-1 (p< 0.0001), uPA (p= 0.006), endoglin (p= 0.008), and CA9 (p <0.0001) were all significant as univariate continuous biomarkers for predicting PFS to first-line trastuzumab-containing therapy, but VEGF was not. In multivariate analysis for PFS with all six biomarkers, only serum CA9 (p= 0.002) was a significant independent covariate. For OS, pretreatment serum HER2 (p= 0.018), TIMP-1 (p< 0.0001), uPA (p< 0.0001), endoglin (p= 0.002), and CA9 (p< 0.0001) were all significant as univariate continuous biomarkers for prognosis, but serum VEGF was not. In multivariate analysis for OS with all six biomarkers, only serum CA9 was a significant independent prognostic covariate (p= 0.001). Conclusions: Elevated pretreatment serum CA9 (a marker of hypoxia) predicts reduced progression-free survival and overall survival in metastatic breast cancer patients treated with first-line trastuzumab-containing therapy. These serum biomarkers deserve further study in larger trials of HER2-targeted breast cancer treatment. Supported by a grant from Komen for the Cure. [Table: see text]

1063 Background: Less than 10% of breast cancer patients are diagnosed with metastatic disease upon initial diagnosis. Once metastases are detected, median survival ranges between 18 and 24 months. Many new chemotherapy agents, hormonal therapy, monoclonal antibodies and supportive care options were presented during the last decade. Although a few randomized trials have demonstrated improvement in survival for various agents, it has not been clear whether the overall survival of these patients has improved. In this study, we analyzed the survival of patients diagnosed with metastatic breast cancer in during the 1990’s Methods: We have analyzed 874 patients diagnosed with breast cancer at our Institute in the years 1991–1994 and 1102 patients in 1996–1999. Tumor characteristics, treatments, and the outcomes of these patients were compared. We used Kaplan-Meier, Wilcoxon test and Cox proportional hazard in order to investigate variants between the 2 groups. Results: After excluding all women with no evidence of metastatic disease at diagnosis, we analyzed 96 patients. No major difference in tumor characteristics was found between the group of patients diagnosed in the early 1990’s and the group diagnosed in the late 1990’s. We found a significant relationship between the period of diagnosis of metastatic breast cancer and survival: median survival was 19 months for the first group and 35 months for the second group (p=0.0398, 95% C.I), with 5-year overall survival rates 8% for patients diagnosed in the early 1990’s and 25% for patients diagnosed in the late 1990’s, p=0.0497. Two years survival was 25% and 60% respectively, although insignificant, p = 0.0941. Although there was no significant difference in number of chemotherapy courses given in the 2 groups, many more new generation treatments were used for the late 90th group. The Hazard of death within 5 years for patients treated with at least one new generation protocol was 0.53, p= 0.004. Conclusions: This study suggests that there has been significant survival improvement in breast cancer patients diagnosed with synchronous metastasis during the second half of the 1990’s. This improvement can be explained by the introduction of new treatments agents and strategies during the last decade No significant financial relationships to disclose.

38 Background: About half of HER2-positive metastatic breast cancer patients will respond tofirst-line trastuzumab-containing therapy, but most will progress within a year. Trastuzumab resistance remains a vexing clinical problem, and better predictive and prognostic biomarkers are needed. Activin A is a TGF-B superfamily member and regulates cell proliferation, apoptosis, differentiation, and immune response. Methods: Serum activin A was measured using ELISA (R&D Systems, Minneapolis, MN) in 60 metastatic breast cancer patients before starting first-line trastuzumab-containing therapy. Progression-free survival (PFS) and overall survival (OS) were analyzed using the Kaplan-Meier method and Cox modeling with both continuous and dichotomous (median) serum activin A analyses. Results: Pretreatment serum activin A levels averaged 2376 pg/ml, and had a median of 629 pg/ml and 25th and 75th quartile values of 406 and 1791 pg/ml, respectively. Patients who were hormone receptor negative had significantly higher activin A levels (median 1287 vs 450 pg/ml, p=0.002). Higher serum activin A was significant on a continuous basis for predicting reduced PFS to first-line trastuzumab-containing therapy (p<0.003), and for predicting shorter OS (p<0.0001). When analyzed using a dichotomous (median) cutpoint, the elevated serum activin A cohort had a significantly reduced PFS (HR 2.79, p <0. 002) (median 6.6 mo vs. 31.1 mo) and OS (HR 5.24, p <0.0001) (median 19.6 mo vs. median not reached). In multivariate analysis for PFS with other covariates (age, line of therapy, CA 15-3, and hormone receptor status), activin A was the only significant covariate (p=0.021). In multivariate analysis for OS, activin A (p=0.002) and CA 15-3 (p=0.03) remained significant as prognostic factors. Conclusions: Elevated pretreatment serum activin A predicts reduced PFS and overall survival in metastatic breast cancer patients treated with first-line trastuzumab-containing therapy. Activin A deserves further study as an adverse biomarker, and to select patients most likely to respond to activin A-targeted therapy.
