This study correlates the disease-free survival (DFS), distant disease-free survival (DDFS), and survival (S) of 1,157 histologically node negative breast cancer patients with the estrogen and/or progesterone receptor (ER, PR) and with the nuclear or histologic grade (NG, HG) of their tumors. All were treated by operation without systemic adjuvant therapy. The DFS, DDFS, and S were significantly greater (P = .005, .004, less than .001) in patients with ER positive than ER negative tumors but the magnitude of the differences after 5 years of follow-up was slight (8% in both DFS and DDFS and 10% in S). Differences of that magnitude are insufficient to discriminate clearly between patients who should or should not receive systemic therapy. As with ER, there were outcome differences in favor of PR positive tumors but only in S was the difference significant (8% at 5 years; P = .002). When combined with ER, PR made no independent contribution in the outcome prediction. Regression analysis indicated that NG was the most important single marker of outcome. The prognosis of women with unknown ER or PR was equivalent to or better than that in those with ER or PR positive tumors. This finding seems to be related to tumor size in that a higher proportion of tumors with unknown receptors were less than 1.0 cm, thus having insufficient tissue for analysis. Our findings disclose that in node negative breast cancer patients, NG is a better marker of prognosis than is tumor ER, and that PR is of little or no value. Tumor NG may also be useful for selecting the type of systemic therapy to be used in these patients.

AbstractObjectiveThe aim of our study was to systematically evaluate the prognostic effects of various circrnas and to explore the prognostic value of circRNAs in breast cancer patients.MethodsA systematical search was conducted on PubMed, Scopus, EMBASE, and the Cochrane Library databases. Eligible studies reporting on the association among circRNAs and prognostic values of breast cancer patients were included. Fixed-effects and random effects models were used to calculate the pooled hazard ratio values of overall survival and disease free survival. In addition, funnel plots were used to qualitatively analyze the publication bias.Results28 studies were included in our meta-analysis. The pooled hazard ratio values of overall survival and disease free survival related to different circRNAs expression in breast cancer patients were 1.68 (1.44-1.97), 2.63 (1.95-3.53).We have identified a total of 28 circRNAs including 19 significantly up-regulated expression circRNAs and 9 significantly down-regulated expression circRNAs in BC(breast cancer) patients. Moreover, all of them revealed mechanisms and have the function of promoting or inhibiting the proliferation, metastasis or invasion of breast cancer cells by acting on the corresponding target.ConclusionOverall, specific circRNAs are significantly associated with the prognosis of BC patients and potentially eligible for the prediction of patients survival. It also provides a potential value for clinical decision-making development and may serve as a promising circRNAs-based target therapy waiting for further elucidation.

PURPOSE: According to one of the most recent key scientific questions concerning the use of biomarkers in clinical trials, we investigated whether node-negative breast cancer patients, defined as high-risk cases on the basis of tumor cell proliferation, could benefit from cyclophosphamide, methotrexate, and fluorouracil (CMF) adjuvant therapy. PATIENTS AND METHODS: Two hundred eighty-one patients with negative nodes and rapidly proliferating tumors, defined according to thymidine labeling index (TLI), were randomized to receive six cycles of CMF or no further treatment after surgery ± radiotherapy. RESULTS: The 5-year disease-free survival (DFS) was 83% for patients treated with CMF compared with 72% in the control group (P = .028). Adjuvant treatment reduced both locoregional and distant metastases. When clinical outcome was analyzed in cell kinetic subgroups characterized according to tertile criteria, compared with patients in the control arm, 5-year DFS was significantly higher after adjuvant CMF in patients with TLI values in the second (78% v 88%, respectively; P = .037) and third tertiles (58% v 78%, respectively; P = .024). CONCLUSION: The results from this randomized clinical study indicate that patients with node-negative, rapidly proliferating tumors significantly benefit from adjuvant CMF.

The aim of our study was to set up a panel for targeted sequencing of chemoresistance genes and the main transcription factors driving their expression and to evaluate their predictive and prognostic value in breast cancer patients. Coding and regulatory regions of 509 genes, selected from PharmGKB and Phenopedia, were sequenced using massive parallel sequencing in blood DNA from 105 breast cancer patients in the testing phase. In total, 18,245 variants were identified of which 2565 were novel variants (without rs number in dbSNP build 150) in the testing phase. Variants with major allele frequency over 0.05 were further prioritized for validation phase based on a newly developed decision tree. Using emerging in silico tools and pharmacogenomic databases for functional predictions and associations with response to cytotoxic therapy or disease-free survival of patients, 55 putative variants were identified and used for validation in 805 patients with clinical follow up using KASPTM technology. In conclusion, associations of rs2227291, rs2293194, and rs4376673 (located in ATP7A, KCNAB1, and DFFB genes, respectively) with response to neoadjuvant cytotoxic therapy and rs1801160 in DPYD with disease-free survival of patients treated with cytotoxic drugs were validated and should be further functionally characterized.
