Background: Triple-negative subtype does not have any of the receptors that are commonly found in breast cancer. Patients suffering from Triple-negative breast cancer are at risk of early metastasis and BRCA mutation. The conversion of the receptors during the metastatic progression or local recurrence of breast cancer is a well-known topic that affects the therapeutic measures and outcome. Confirmation of immunohistochemistry is essential in these conditions, but genetic evaluation is controversial. Case presentation: A woman suffering from primary luminal breast cancer presented with femoral bone metastasis in the follow-up after two years. Bone metastasis was compatible with the triple-negative subtype. This case was discussed at the weekly breast multidisciplinary team session of the Department of Breast Surgery, Tehran University of Medical Sciences.Question: Does the patient need genetics counseling in a conversion setting? And does the new specimen need CISH/FISH techniques to confirm TNBC tumors?Conclusion: There are no strong guidelines to recommend genetic counseling and BRCA testing for patients with breast cancer biomarkers conversion. Re-assessing the specimen for ER, PR, and HER-2 is necessary for this setting.

594 Background: Triple negative (TN) basal-like breast cancers (Negative for ER,PR,HER2/neu) represent an aggressive phenotype, with unique clinical and pathologic features. The purpose of this study was to determine the prognostic significance of this classification with respect to local-regional relapse and distant metastasis in a cohort of conservatively managed breast cancer patients. Methods: A large data base of conservatively managed breast cancer patients with long term follow-up, in which all three immunhistochemical markers, ER,PR and HER2/neu were available was reviewed. Patients were classified as TN if they tested negative for all three markers. Of 442 patients in the data base with all three markers available, 100 were classified as TN. All clinical, pathologic, outcomes and molecular marker data were entered into a computerized database. Results: As of September 2005, with a median follow-up of 7 years, of the 442 patients in the study there have been 50 in-breast relapses, 10 nodal relapses, 68 distant relapses and 62 deaths. Compared with the other subtypes, the TN cohort had a poorer overall survival (67% vs 75%, p = .096), poorer distant metastasis-free rate (61% vs 75%, p = .002), poorer cause-specific survival (67% vs 78%, p = .03), and poorer nodal relapse-free rate (93% vs 99%, p = .021). In a multivariate Cox regression analysis, TN subtype was an independent predictor of distant metastasis (HR=2.6, CI 1.53–4.35, p = .004) and cause- specific survival (HR= 2.36, CI 1.28–4.38, p= .006). There was no significant difference in local (in-breast) control between the TN and other subtypes. BRCA testing was performed on 85 patients in this cohort, of whom 8 had deleterious mutations in BRCA1 and 6 had deleterious mutations in BRCA2. Of 8 BRCA1 mutant patients 7 were classified as TN, while only 1 of 6 BRCA2 patients were TN (p < .001). Conclusions: Patients classified as TN have a poor prognosis with respect to overall, disease free and cause specific survival. However there was no evidence that these patients are at higher risk for local relapse following conservative surgery and radiation. BRCA1 mutant patients develop predominantly TN tumors.

11017 Background: Since the BRCA gene is responsible for excisional DNA repair, we hypothesized that breast cancer patients with BRCA mutation would be more susceptible to the induction of second malignancies following chemotherapy treatment than breast cancer patients who tested negative for BRCA mutations. Methods: Breast cancer patients tested for BRCA1 and BRCA2 mutations at the Cleveland Clinic were identified and evaluated for history of neoadjuvant or adjuvant chemotherapy and for the occurrence of subsequent non-breast primary invasive cancer. Patients with inadequate follow-up and those with inoperable disease at diagnosis were excluded from the analysis. Fisher’s exact test was used to compare different cohorts. The IRB at Cleveland Clinic approved the study. Results: Of 115 identified breast cancer patients tested for BRCA mutations, 77 met the inclusion criteria. Twenty-seven of these patients carried BRCA1 or BRCA2 mutations and 50 tested negative for these mutations. Twelve patients (44%) in the BRCA positive group and 8 patients (16%) in the BRCA negative group underwent prophylactic oophorectomy. Median follow-up for the two groups was 53.5 months (75 months in the BRCA positive group and 48.5 months in the BRCA negative group). Median age at diagnosis was 42 years (40.5 years in the BRCA positive group and 44.5 in the BRCA negative group). In the BRCA positive group 3 of 25 patients (12%) treated with chemotherapy developed second malignancies (ovarian cancer, transitional cell cancer in urinary tract and renal cell carcinoma) compared with none of the 2 patients who did not get chemotherapy (p= 1.0). In the BRCA negative group, 2/34 patients (6%), treated with chemotherapy developed second cancers compared with 2/16 patients (12%), who were not treated with chemotherapy (p=0.58). Cancers in the BRCA negative group included two bladder carcinomas in the chemotherapy treated patients and in the non-chemotherapy group, non-small cell lung cancer, uterine, ovarian, endometrial and peritoneal cancers. Conclusions: At more than 4-years of follow up, chemotherapy in operable breast cancer patients was not associated with an increase in the risk of secondary malignancy or with a differential effect on this endpoint by BRCA mutation status in this retrospective study. No significant financial relationships to disclose.

e13072 Background: Bone Metastases (BM) are still the main cause of morbidity and morbility in cancer patients because of their complications defined as skeletal-related events (SREs).SREs reduce pts quality of life and are associated with an increasing in social and health costs. At present, data concerning BM are mainly obtained retrospectively from monocentric experiences. Methods: We performed a multicentre prospective observational study of patients with BM from breast cancer (BC) with at least 6 month (m)'s follow-up who were registered in a prospective BM database (BMDB). Detailed information on patients at first diagnosis of BM was recorded in a custom-built software system, updated every 6 m by participating centres and reviewed by the coordinator centre.All pts have signed an informed consent. Results: Since October 2014,618 pts with BM from solid tumors were enrolled of whom 220 have BC as primitive site with a 6 m follow-up. Median age was 62 y (range 26-86). Median Follow up was 34 m (6-149). At enrolment 109 (50%) had only BM and 109 (50%) pts had concomitant visceral and BM. Median time to first BM was 47 m (range 0-312) in Bone only disease and 78.6 m in pts with visceral bone metastases. Disease Free interval (DFI) was different according to BC molecular subtypes and stage. The univariate hazard ratio (HR) for visceral or bone metastasis was higher in luminal B tumors (1.56, 95% confidence interval [CI]:1.1-2.3) (p = 0.002), basal-like (2.50, 95% CI:1.1-6.0) (p = 0.043), and HER2-enriched tumors (1.37, 95% CI:0.78-2.4) (p = 0.273). DFI for pts with stage I disease at diagnosis of primary BC was longer than that for stage III pts (median 67.2 m, 95%CI:53.1-96.1, vs. 58.1 m, 95%CI:41.9-73.4), with a HR of 1.84 (95% CI:1.1-3.0) (p = 0.015) for the stage III group, and 0.98 (95% C.I.:0.6-1.5) (p = 0.930) for the stage II group. During BM disease, 98 pts had at least 1 SREs . Zoledronate was used in 69.1% and Denosumab in 28.3% of cases. First line treatment was hormone-based (n = 105, 50.7%) chemo-based therapy (n = 80, 38.7%) and chemo+ormono based (n = 20, 9.7%). During follow up progression disease occurred in 167 pts. Median progression-free (mPFS) and overall survival calculated from metastatic disease diagnosis (mOS) were 15.1 m (95%CI 12.6-18.4) and 66.8 m (95%CI 52.1-79.2),respectively. Conclusions: This study presents prospective data about a cohort of BC pts enrolled at the first BM occurrence and followed over the time, extrapolated by the multicentric observational BMDB in order to better understed the clinical history of breast cancer and bone metastases.

Abstract Many studies have demonstrated that osteopontin (OPN) contributes functionally to aggressive behaviour in many tumours including breast cancer. This study aims to investigate its role as a simple biochemical marker easily measured in plasma of breast cancer patients to give an early signal for metastases and to detect its relationship to clinicopathological findings and survival. We measured plasma OPN, CA15.3 and serum alkaline phosphatase (ALP) activity in 55 patients, 28 with early stage breast cancer and 27 with bone metastasis out of whom 20 had metastasis in other sites. The median age at diagnosis for non-metastatic cases was 60 years (range 35-85) and for metastatic cases was 45.5 years (range 32-59). In the non-metastatic group, 78.57% of the patients were histologically graded as grades I and II and 21.43% as grade III tumours. In the metastatic group, 81.48% of the patients had grades I and II and 18.52% had grade III tumours; 54% of patients in the non-metastatic group were at stage II and 46% were at stage III at presentation. All patients of group II had bone metastasis, 33% had liver metastases, 25.9% had lung metastasis and 14.8% had lymph node metastasis. Patients with non-metastatic disease had a median OPN level of 55 ng/ml (range 54-150 ng/l), while those in the metastatic group had a median of 148.0 ng/l (range 56.0-156.0 ng/l), a difference which was statistically significant (P = 0.001). There was no statistically significant difference in the median levels of CA15.3 and ALP between both groups. The median OPN level was significantly higher with serum ALP level above 90, progesterone receptor (PR) status, bone and visceral metastasis. Median OPN was not affected significantly by menopausal status (P-value 0.3), tumour grade (P-value 0.3), estrogen receptor (ER) status (P-value 0.7), pathological type (P-value 0.42) or serum CA15.3 level (P-value 0.6). At the end of 12-year follow-up, 83% of the patients survived (92.3% in the non-metastatic versus 74.1% in the metastatic group). The estimated median survival for the whole study population at 12 years was 13 years (95% CI 8.144-17.856). The estimated median survival was 13 years (95% CI 0) and 12 years (95% CI 4.893-19.11) in patients with median OPN levels of <142 and ≥142, respectively, a difference which was not statistically significant (P = 0.343). No statistically significant difference in overall survival OS was noticed in relation to menopausal status (P = 0.7), pathological type (P = 0.4) and hormone receptor status (P = 0.3). At 6-year follow-up, it was found that OS was affected by the presence of visceral metastasis, tumour grade, serum plasma level of ALP and the serum level of CA15.3 (P = 0.0006, 0.007, 0.001 and 0.03, respectively). However, the presence of bone metastasis did not affect OS (P = 0.6). Osteopontin level can be a simple biochemical marker easily measured in plasma of breast cancer patients to give early signals for metastases, but not a prognostic factor for survival.

BackgroundBreast cancer is the most commonly diagnosed cancer worldwide. However, the well-known biomarkers are not enough to meet the needs of precision medicine. Novel targets are desirable and highly valuable for improved patient survival. In this regard, we identified complement component C7 as one of the candidates based on data from the OCOMINE database.MethodsC7 expression was examined by immunohistochemistry in 331 cases of invasive ductal carcinoma (IDC), 45 cases of ductal carcinoma in situ (DCIS), and 52 cases of non-neoplastic tissues adjacent to tumor. Then, C7 expression was further confirmed by Western blot analysis based on IDC specimens and non-neoplastic breast specimens. The relationship between the C7 expression and prognosis of breast cancer patients was analyzed in order to investigate the function of C7 in breast cancer patients. Meanwhile, we also analyzed the relationship between the C7 expression and prognosis of 149 patients treated with conventional TE (taxane and anthracycline)-based chemotherapy. Then, a cohort of patients (22 cases) treated with TE neoadjuvant chemotherapy was used to further confirm the relationship between the C7 expression and TE-based chemosensitivity.ResultsIn our present study, we reported for the first time that C7 was an independent prognostic factor of breast cancer and C7 expression of IDC tissues was higher than non-neoplastic tissues adjacent to tumor and DCIS. In a cohort of 331 IDC patients, high expression of C7 indicated poor prognosis especially in the triple negative subtype and luminal B subtype. Furthermore, C7 was also a promoting factor for triple negative subtype patients to develop bone metastasis. Meanwhile, we provided the first evidence that patients with high C7 expression were insensitive to TE (taxane and anthracycline)-based chemotherapy by analyzing a cohort of 149 patients treated with TE-based chemotherapy and another cohort of 22 patients treated with TE neoadjuvant chemotherapy.ConclusionsIn summary, high expression of C7 may promote breast cancer development and might be insensitive to TE-based chemotherapy. Our present study laid a foundation to help clinicians improve the identification of patients for TE-based chemotherapy by C7 in the era of precision medicine.
