1514 Background: Selective estrogen receptor modulators (SERMs) reduce the risk of breast cancer. Acceptance of SERMs is low due to toxicities. Agents with a better toxicity profile and surrogate endpoint biomarkers to evaluate the effect of preventive agents are needed. In addition to reducing the risk of recurrence of breast cancer, the aromatase inhibitors (AI) have been shown to reduce the risk of contralateral breast cancer in large phase III adjuvant studies. Our objective in this prospective short-term prevention study was to evaluate the effect of anastrozole on surrogate endpoint biomarkers in breast tissue and serum of women with breast cancer who are at increased risk for developing a contralateral second primary breast cancer. Methods: Women with a history of stage I, II breast cancer who were scheduled to start anastrozole for standard adjuvant treatment were eligible. After signing informed consent, patients underwent baseline fine needle aspiration (FNA) of the unaffected breast and serum collection for biomarker analysis before starting anastrozole at 1 mg per oral /day. A repeat FNA and serum collection were performed after 6 months of therapy. Biomarker endpoints included changes in ER and KI-67 expression in breast tissue analyzed by immunohistochemistry and insulin-like growth factor binding protein (IGFBP-1) in serum analyzed by ELISA. The difference in biomarkers before and after treatment was assessed using a Wilcoxon signed-rank test. Results: Forty two patients were enrolled and accrual has been completed. Median age was 58.8 (range 48–75). There was no change in ER or Ki-67 expression in pre- and posttreatment FNA samples. However, there was a statistically significant difference in pre- and posttreatment serum IGFBP-1 levels (p = 0.014); with pre-and post- mean treatment levels being 9.2 ng/mL and 13.5 ng/mL, respectively. Conclusions: We found a significant modulation of IGFBP-1 levels with 6 months of anastrozole treatment in women at increased risk of developing contralateral breast cancer. Anastrozole is currently being studied as a prevention agent in a large phase III trial, and our results provide support for continued evaluation of IGFBP-1 as a surrogate endpoint biomarker in prospective breast chemoprevention studies.

Abstract Whereas longstanding dogma has purported that pregnancies protect women from breast cancer, a recent meta-analysis now mandates reconsideration since it reported an actual higher breast cancer risk for more than two decades after childbirth before the relative risk turns negative. Moreover, the risk of breast cancer appears higher for women having their first birth at an older age and with a family history and it is not reduced by breastfeeding. The process of obtaining informed consent for all fertility treatments, therefore, must make patients aware of the facts that every pregnancy, to a small degree, will increase the short-term breast cancer risk. This observation may be even more relevant in cases of surrogacy where women agree to conceive without deriving benefits of offspring from assuming the risk, thus creating a substantially different risk-benefit ratio. Consequently, it appears prudent for professional societies in the field to update recommendations regarding consent information for all fertility treatments but especially for treatments involving surrogacy.

Context: Breast cancer (BC) is the most common cancer in women worldwide. Hereditary susceptibility created by mutations in autosomal dominant genes is responsible for 5 to 10% of all BC cases in women. Recent studies have identified genes associated with increased risk for aggressive BC, providing the basis for better risk management. Evidence Acquisition: The latest information in National Center for Biotechnology Information (NCBI), Google Scholar, ScienceDirect, and Scopus were the main databases for finding articles. A combination of keywords of ‘metastasis’, ‘invasion’, ‘aggressive breast cancer’, ‘prognostic factor’, ‘mutation’, and ‘cancer treatment’ was searched in the databases to identify related articles. Titles and abstracts of the articles were studied to choose the right articles. Results: Mutations in breast cancer type 1 susceptibility protein (BRCA1) and breast cancer type 2 susceptibility protein (BRCA2) genes are two central players related to the high risk of BC. Mutation in tumor protein p53 (TP53) is another important mutation that leads to triple-negative BC. Although the majority of BC types are not associated with high-throughput mutant genes such as BRCA1, BRCA2, and TP53, they are associated with low-throughput genes, including DNA repair protein Rad50 (RAD50), Nijmegen breakage syndrome gene (NBS1), checkpoint kinase 2 (CHEK2), BRCA1-interacting protein 1 (BRIP1), E-cadherin gene (CDH1) and PALB2, UCHL1, aldehydedehydrogenase1A3 (ALDH1A3), androgen receptor (AR), 5-bisphosphate 3-kinase (PIK3CA), phosphatidylinositol-4, and luminal gene expression that are generally mutated in the global population. High tumor mutational burden (TMB) was associated with improved progression-free survival. Conclusions: The lymph node status, early tumor size, ER, PR, human epidermal growth factor receptor-2 (HER2), and Ki-67 are conventional prognostic factors for BC. However, these factors cannot exactly predict the aggressive behavior of BC. Hence, in this review, we discussed new prognostic factors of aggressive BCs that are useful for the treatment of patients with BC.

PURPOSE That patients can be ultimately cured of breast cancer has been questioned, because late deaths from the disease have been observed even several decades after the diagnosis. The purpose of this study was to investigate late mortality caused by breast cancer. PATIENTS AND METHODS Using the files of local hospitals and the Finnish Cancer Registry, we identified all patients with histologically diagnosed invasive breast cancer in a defined urban area (city of Turku, Finland) from 1945 to 1969 (n = 601). In 563 cases (94%), clinical data and histologic and autopsy slides could be reviewed, and these women had been monitored for a median of 29 years (range, 22 to 44; n = 66) or until death (n = 497). RESULTS Mortality from breast cancer was observed even during the fourth follow-up decade, but if women who were diagnosed with contralateral breast cancer were excluded (n = 30), no deaths from breast cancer were identified after the 27th year of follow-up evaluation. The 30-year survival rates were 62% (95% confidence interval [CI], 54% to 70%), 19% (95% CI, 13% to 25%), and 0% for women with pN0 (node-negative) and pN1 or pN2 (node-positive) disease, respectively. High 30-year survival rates were found in small (pT1N0M0) unilateral cancers (80% alive; 95% CI, 66 to 94%), and in the lobular (45% alive; 95% CI, 31% to 59%) and the special histologic types (81% alive; 95% CI, 67% to 95%). These survival rates were obtained when correcting either for known intercurrent deaths or for mortality in the age- and sex-matched general population. CONCLUSION Breast cancer, node-negative and node-positive, may be permanently cured even if treated with locoregional therapy only. The survival figures listed here may be considered as minimum values, because women with breast cancer diagnosed in the same area from 1970 to 1984 showed significantly improved short-term (< 20 years) survival rates over those diagnosed from 1945 to 1969.
