Background: Breast cancer is the most frequently diagnosed cancer among women in 140 of 184 countries worldwide.  The association between breast cancer survival and socio-demographic and pathologic factors has been widely studied in the developed countries. But scarce data is available from Saudi Arabia. We aimed to determine the overall observed one year and three years survival rate of female breast cancer patients and to investigate the factors affecting survival rate. Methods: Retrospective data was collected from the cancer center registry at King Fahad Medical City (KFMC) that included all women diagnosed with breast cancer between 1st January 2011 till 31st December 2012 and were followed to 31st December 2015 (cut off point for follow-up). Kaplan-Meier analysis was done to assess overall survival. The factors affecting survival rate such as age, histological type, tumor grade at diagnosis, metastases and treatment options were investigated using log rank test and Cox regression analysis. Results: The overall observed survival probability of the study population at 1, and 3 years was 95%, and 85%, respectively. The 3 year survivals for the younger (≤40 years), 41-50 years and older (50+ years) patients were 83.9%, 90.6% and 80.6% respectively, the differences not reaching statistical significance. There were statistically significant associations between three year survival and histological type of tumour, laterality, metastases and type of treatment by the univariate analysis log rank test. Conclusions: One and three-year survival rate of breast cancer at KFMC was 96% and 85% respectively. Investigating the factors affecting survival rate is one of the most essential means of improving cancer prognosis.

e23173 Background: Breast cancer is one of the top causes of cancer death worldwide. In Mexico, locally advanced breast cancer (LABC) comprises the majority of the breast cancer stages at diagnosis. Recent studies have suggested that 5-hydroxymethylcytosine (5hmC), could be a prognostic marker in breast cancer. However, the role of 5hmC on clinical and histopathologic characteristics in LABC has not been explored. Methods: From a cohort of locally advanced and advanced breast cancer patients treated at the National Cancer Institute in Mexico City with a 3-year follow-up, we measured 5hmC levels by immunodetection from fresh frozen tissue samples taken from the initial biopsy (N = 193). We determined the association between 5hmC levels and the most relevant clinical and histopathological characteristics. Results: From the full cohort analyzed; 42% were luminal A (n = 82), 33% were luminal B (N = 63), 9% were HER2-positive (N = 18), and 15% were triple-negative tumors. We found higher levels of global 5hmC in HER2 positive tumors vs. all other subtypes (p = 0.028, Kruskal-Wallis test). In luminal B tumors, 5hmC levels were associated with Ki67 (β = -0.04, 95%CI: -0.08, -0.01, p = 0.01 from multivariable model) but not in luminal A. Furthermore, we found that low 5hmC levels were associated with higher histological grade in HER2-positive tumors (p = 0.03, Kruskal-Wallis test). In subgroup analysis of LABC patients, we found higher 5hmC levels in non-ductal vs. ductal invasive tumors (β = 1.38, 95%CI: 0.049, 2.911, p = 0.043 from multivariable model). Also, lower 5hmC levels were associated with Ki67 (β = -2.53, 95%CI: -4.32, -0.74; p = 0.009 from multivariable model) and with histological type (p = 0.028, Kruskal-Wallis test) in LABC luminal B tumors. A borderline association with OS (p = 0.07, log-rank test) and RFS (p = 0.071, log-rank test) was observed in luminal A tumors in the LABC group. Conclusions: Our findings suggest that 5hmC levels are differentially associated with distinct clinical and histopathological characteristics in breast cancer, especially those linked to aggressiveness, including Ki67, histological type, and grade.

Abstract Background: Breast cancer is the most common cancer among women in the world. NKX6.1 is proved to be involved in several human cancers, but fewer researches have reported the functional roles of NKX6.1 in breast cancer. In this study, we investigated the clinical significance of NKX6.1 expression in breast cancer prognosis.Methods: The expression level of NKX6.1 in breast cancer tissues and paired non-cancerous tissues were detected by quantitative real-time polymerase chain reaction (qRT-PCR). Chi-square test was applied to evaluate the relationship between NKX6.1 expression and clinicopathologic parameters. The overall survival of breast cancer patients were analyzed by Kaplan-Meier method with log rank test. Additionally, cox regression analysis was used for prognosis analysis.Results: NKX6.1 expression level is increased in breast cancer tissues (P<0.001). Moreover, the elevated levels were significantly correlated with tumor size (P=0.002), TNM stage (P=0.018) and lymph node metastasis (P=0.007). In addition, breast cancer patients with high NKX6.1 level had a poorer overall survival than those with low level (log rank test, P=0.001). NKX6.1 was an independent prognostic factor for breast cancer (HR=2.961, 95%CI=1.368-6.411, P=0.006).Conclusions: NKX6.1 is up-regulated in breast cancer, which may be a potential prognostic biomarker for the cancer.

Background For patients initially diagnosed with metastatic Her2-positive breast cancer (MHBC), we intended to construct a nomogram with risk stratification to predict prognosis and to explore the role of local surgery. Methods We retrieved data from the Surveillance, Epidemiology, and End Results (SEER) database. Kaplan–Meier (KM) method and log-rank test were used for the selection of significant variables. Cox regression analysis and Fine-Gray test were utilized to confirm independent prognostic factors of overall survival (OS) and breast cancer-specific survival (BCSS). A nomogram predicting 1-year, 3-year, and 5-year OS was developed and validated. Patients were stratified based on the optimal cut-off values of total personal score. KM method and log-rank test were used to estimate OS prognosis and benefit from local surgery and chemotherapy. Results There were 1680 and 717 patients in the training and validation cohort. Age, race, marriage, T stage, estrogen receptor (ER) status, visceral metastasis (bone, brain, liver and lung) were identified as independent prognostic factors for OS and BCSS, while histology was also corelated with OS. C-indexes in the training and validation cohort were 0.70 and 0.68, respectively. Calibration plots indicated precise predictive ability. The total population was divided into low- (<141 points), intermediate- (142–208 points), and high-risk (>208 points) prognostic groups. Local surgery and chemotherapy brought various degrees of survival benefit for patients with diverse-risk prognosis. Conclusions We constructed a model with accurate prediction and discrimination. It would provide a reference for clinicians' decision-making. Surgery on the primary lesion was recommended for patients with good physical performance status, while further study on optimal surgical opportunity was needed.

AbstractMale breast cancer (MBC) is a rare disease. Due to its rarity, treatment is still directed by data mainly extrapolated from female breast cancer (FBC) treatment, despite the fact that it has recently become clear that MBC has its own molecular characteristics. DDX3 is a RNA helicase with tumor suppressor and oncogenic potential that was described as a prognosticator in FBC and can be targeted by small molecule inhibitors of DDX3. The aim of this study was to evaluate if DDX3 is a useful prognosticator for MBC patients. Nuclear as well as cytoplasmic DDX3 expression was studied by immunohistochemistry in a Dutch retrospective cohort of 106 MBC patients. Differences in 10-year survival by DDX3 expression were analyzed using log-rank test. The association between clinicopathologic variables, DDX3 expression, and survival was tested in uni- and multivariate Cox-regression analysis. High cytoplasmic DDX3 was associated with high androgen receptor (AR) expression while low nuclear DDX3 was associated with negative lymph node status. Nuclear and cytoplasmic DDX3 were not associated with each other. In a univariate analysis, high cytoplasmic DDX3 (p = 0.045) was significantly associated with better 10-year overall survival. In multivariate analyses, cytoplasmic DDX3 had independent prognostic value (p = 0.017). In conclusion, cytoplasmic DDX3 expression seems to be a useful prognosticator in MBC, as high cytoplasmic DDX3 indicated better 10-year survival.

Abstract The LRF CLL4 trial randomised 777 previously untreated patients with Binet stage progressive A, B or C disease between January 1999 and October 2004 to receive either Chlorambucil, Fludarabine or Fludarabine and Cyclophosphamide. Interphase FISH for deletions of chromosome 6q, 11q, 13q, 17p and trisomy 12, IgVH gene mutational status (98% cut off), CD38 (7% cut off) and ZAP70 (10% cut off) expression were measured at randomisation on 579, 523, 535 and 478 patients respectively. Leukemic cells from 39 patients utilised the VH3-21 gene of whom 33 had homologous CDR3’s. Among the biological markers, log rank analysis showed that >20% p53 loss, del 11q, unmutated VH genes, high CD38 and high ZAP 70 correlated with disease progression or death (Table 1) but not deletion of chromosome 6q, 13q and trisomy 12 (p=0.7, 0.3 and 0.2 respectively). There was no difference in PFS or response duration between the 52 patients with 5–20% p53 loss and the 494 patients with no p53 loss. Multivariate Cox regression analysis showed that >20% p53 loss (p<0.0001), unmutated IgVH genes (p=0.0001), deletion of 11q (p=0.02) and male gender (p=0.03) were independent risk factors for short PFS. The effects of stage and age were overridden by FISH abnormalities. High ZAP70 expression was only significant when VH gene mutation status was not included in the model. CD38 expression was only significant in univariate analysis. Table 1 Variable Progression or Death/N Univariate p-value(log rank test) Gender Male 384/573 0.002 Female 111/204 17q(p53) No 131/546 <0.00005 Yes 21/33 IgVH Unmutated 105/203 <0.00005 Mutated 225/320 del 11q No 288/463 <0.00005 Yes 87/116 ZAP70 Negative 140/242 0.003 Positive 158/236 CD38 Negative 110/201 0.0001 Positive 227/334 Among the 320 unmutated cases there was no significant difference in PFS between those with 100% homology (227 cases) and those with 99% or 98% homology to the germline sequence (93 cases). Mutated VH3-21 cases were more likely to express ZAP70 than other mutated cases, p=0.004. Excluding patients with >20% p53 loss, patients using the VH3-21 gene had similar progression free survival (PFS) to those remaining patients with unmutated VH genes and an inferior PFS to those with mutated VH genes (2p=0.0001). The adverse prognostic significance of 11q deletions was not clearly evident in an interim analysis presented at ASH ‘05. Patients can now be divided into 3 risk groups (Table 2). This risk stratification provides the basis of evaluating differing treatment modalities for each risk group in subsequent clinical trials.

Abstract Introduction Paravalvular leakage (PVL) following transcatheter aortic valve replacement (TAVR) is associated with greater mortality. In clinical practice, determining PVL severity after TAVR remains challenging and often requires multiparametric assessment. Purpose This study sought to evaluate the respective value of various modalities of PVL assessments, including transthoracic echocardiography (TTE), cine-angiography, aortic regurgitation index (ARI), and closure time with adenosine diphosphate (CT-ADP), in the prediction of adverse clinical outcomes. Methods We included 1044 patients from our prospective TAVR registry between February 2010 and May 2019. Major adverse cardiac and cerebrovascular events (MACCE) was defined as a composite of all-cause death, myocardial infarction, stroke, and heart failure hospitalization within 1-year. Established cutoff values of ARI (&lt;25) and CT-ADP (&gt;180 sec) were used to assess the presence of PVL after TAVR. Results Moderate to severe PVL occurred in 14.2% and 5.2% of patients as measured by TTE and angiography. The rate of patients with ARI &lt;25 and CT-ADP &gt;180 sec were 36.5% and 24.9%, respectively. Among the four modalities, PVL evaluated by angiography predicted poorer clinical outcomes (Log rank test; p=0.001), whereas TTE, ARI &lt;25, and CT-ADP &gt;180 sec were not associated with 1-year MACCE. By multivariate Cox regression analysis, moderate to severe PVL by angiography was an independent predictor of 1-year MACCE (hazard ratio: 1.96; 95% confidence interval: 1.22–3.00; p=0.007). Conclusions Paravalvular leakage measured by angiography was evidenced as the most meaningful modality in the prediction of adverse clinical outcomes. Future multicenter studies are warranted to ensure these findings in the current TAVR era. Figure 1 Funding Acknowledgement Type of funding source: None

Abstract BackgroundAim of this study was to evaluate the prognostic of tumor volume reduction rate (TVRR) status post induction chemotherapy (IC) in LA-HNSCC.MethodsPatients with newly diagnosed LA-HNSCC from year 2007 to 2016 at a single center were included in this retrospective study. All patients had received IC as TPF (taxotere, platinum, fluorouracil) followed by daily definitive intensity-modulated radiotherapy (IMRT) for 70 Gy in 35 fractions concurrent with or without cisplatin-based chemotherapy. Tumor volume reduction rate of the primary tumor (TVRR-T) and lymph node (TVRR-N) was measured and calculated by contrast-enhanced CT images at diagnosis, and one month after final IC cycle, and analyzed though a univariate and multivariate Cox regression model.ResultsNinety patients of the primary cancer sites at hypopharynx (31/90, 34.4%), oropharynx (29/90, 32.2%), oral cavity (19/90, 21.1%) and larynx (11/90, 12.2%) were included in this study, with a median follow-up time interval of 3.9 years. In univariate Cox regression analysis, the TVRR-T as the only variable showed a significant difference for disease-free survival (DFS) (hazard ratio [HR] 0.77, 95% confidence interval (CI) 0.63 to 0.96; P = 0.02), aside from cancer site, RECIST, age and IC dose. In multivariate Cox regression analysis, The TVRR-T was also an independently significant prognostic factor for DFS (HR 0.77, 95% CI 0.62 to 0.97; P = 0.02). At a cutoff value using TVRR-T of 50% in Kaplan-Meier survival analysis, the DFS was significant higher with TVRR-T ≥ 50% group (log-rank test, p = 0.024), and also a trend of improved OS. (log-rank test, p = 0.069).ConclusionsTVRR-T was related to improved DFS and trend of improved OS. Other factors including patient’s age at diagnosis, the primary cancer site, and RECIST, were not significantly related to DFS.

Background To better understand the clinicopathological features and prognostic profiles of squamous cell carcinoma (SCC) of the breast. Methods Information on breast cancer was obtained from the Surveillance, Epidemiology, and End Results database (2004–2016). Comparative analyses were carried out to investigate the heterogeneity in the clinicopathological characteristics and survival outcomes between SCC and invasive ductal carcinoma (IDC), while propensity score matching was conducted to analyze the variations among baseline characteristics. Prognostic factors for SCC of the breast were successively identified using Cox regression analysis. Results A total of 382 SCC patients and 561477 IDC patients were identified in this study. Comparatively, the SCC cohort exhibited a higher proportion of male individuals, poor differentiation, an advanced TNM stage, an increasing percentage of triple-negative (TN) subtype, an increasing rate of organ involvement, and less access to therapeutics. The aggressive profile was consistent in the TN subgroup, with a significantly higher proportion in SCC than in IDC (25.7% vs 6.8%). Prognosis of SCC was profoundly poorer than that of IDC (mOS, 78.6 months and 121.6 months, P < .0001; mBCSS 91.9 months vs 135.6 months, P < .0001), of which the inferior tendency remained stable among disease stage and therapeutic options, while no difference was detected in the 2 subgroups with the TN subtype. The 2-year survival rate was 66.9% and the 5-year survival rate was 51.4%, with the risk factors being older age, bilateral disease, advanced TNM stage, bone and visceral involvement, surgical intervention, radiation treatment, and chemotherapy. Conclusions This study systematically analyzed the heterogeneous characteristics of SCC of the breast in comparison with IDC. Squamous cell breast cancer presented with increasing aggressive behavior and inferior prognosis. Prospective studies should focus on this subgroup and introduce individualized therapeutic protocols in clinical practice.

Background. Neuroblastomas are the most frequent extracranial pediatric solid tumors. The prognosis of children with high-risk neuroblastomas has remained poor in the past decade. A powerful signature is required to identify factors associated with prognosis and improved treatment selection. Here, we identified a strong methylation signature that favored the earlier diagnosis of neuroblastoma in patients. Methods. Gene methylation (GM) data of neuroblastoma patients from the Therapeutically Applicable Research to Generate Effective Treatments (TARGET) were analyzed using a multivariate Cox regression analysis (MCRA) and univariate Cox proportional hazards regression analysis (UCPHRA). Results. The methylated genes’ signature consisting of eight genes (NBEA, DDX28, TMED8, LOC151174, EFNB2, GHRHR, MIMT1, and SLC29A3) was selected. The signature divided patients into low- and high-risk categories, with statistically significant survival rates (median survival time: 25.08 vs. >128.80 months, log-rank test, P < 0.001 ) in the training group, and the validation of the signature’s risk stratification ability was carried out in the test group (log-rank test, P < 0.01 , median survival time: 30.48 vs. >120.36 months). The methylated genes’ signature was found to be an independent predictive factor for neuroblastoma by MCRA. Functional enrichment analysis suggested that these methylated genes were related to butanoate metabolism, beta-alanine metabolism, and glutamate metabolism, all playing different significant roles in the process of energy metabolism in neuroblastomas. Conclusions. The set of eight methylated genes could be used as a new predictive and prognostic signature for patients with INRG high-risk neuroblastomas, thus assisting in treatment, drug development, and predicting survival.

e13005 Background: In Japan, eribulin has been approved for inoperative or recurrent breast cancer, following treatment with an anthracyclines and a taxanes. We reported the efficacy and safety of eribulin as a first-line to third-line treatment in patients with advanced/metastatic breast cancer (MBC) previously treated with anthracylinsanthracyclines and taxanes (Breast 2017). Briefly, the main inclusion criteria were as follows: no history of eribulin administration; an Eastern Cooperative Oncology Group performance status (ECOG PS) of 0 to 2,; human epidermal growth factor receptor 2 (HER2)-negative,; 20–75 years; ≥4 weeks from the last dose of chemotherapy, or ≥2 weeks from the last dosing of endocrine or radiation therapy; measurable lesion based on Response Evaluation Criteria in Solid Tumors (RECIST) ver. 1.1; sufficient organ function; life expectancy of ≥3 months; and no significant abnormalities on electrocardiogram. Patients in this clinical trial were enrolled between December 1, 2011, and November 30, 2013. Eribulin was administered intravenously at a dose of 1.4 mg/m2 during a 2-5 min infusion on days 1 and 8 every 3 weeks. In contrast, baseline neutrophil-to-lymphocyte ratio (NLR) and absolute lymphocyte count (ALC) were reported to predict progression-free survival (PFS) or overall survival (OS). However, these reports were mainly retrospective analysis. Therefore, retrospective evaluation of NLR/ALC in a prospective clinical trial is important to understand the association between NLR/ALC and OS/PFS. Methods: Of 47 prospectively enrolled patients in a previous trial, 45 patients were retrospectively evaluated for baseline NLR/ACL and at the time of 3 cycles of eribulin. The association between NLR/ALC and OS/PFS was also were analyzed for association with OS/PFS. The Kaplan-Meier method was used to estimate the OS/PFS distribution. The cut-off values for baseline NLR and ALC were set at 3 and 1500 /ul, respectively. Results: The median OS of patients with a baseline NLR < 3 was significantly longer than that of patients with a baseline NLR ≥ ≧3 (769 days vs. 409 days; log-rank test p = 0.0333). The median OS of patients with a baseline ALC ≥ ≧1500 was also significantly longer than that of patients with a baseline ALC < 1500 (964 days vs.vs 427 days; log-rank test p = 0.0425). Association between baseline NLR/ALC and PFS were not seen, and also association between at the time of 3 cycles of NLR/ALC and OS/PFS were not seen neither. Conclusions: Baseline NLR and ALC in the patients with HER2- negative breast cancer who plan to treat eribulin may predict overall survival. Clinical trial information: UMIN000007121.
