e12018 Background: Our goal was to compare clinicopathological characteristics and DFS time among breast cancer patients diagnosed with mammography or symptoms. Methods: This was retrospective analysis of 828 patient files. Diagnosis was done with mammography or symptom,considering the followings:age,menopause,hormone and HER2 receptor,grade,histologic subtype,lymphovascular(LVI) and perineuronal invasion(PNI),adjuvant chemotheraphy,adjuvant herceptin,adjuvant hormone and adjuvant radiotheraphy use.Recurrence dates,locations and last appointment dates were noted. Results: Breast cancer was detected by mammography in 324 patients vs by sysmptom in 504.The difference in most cases between these two methods were significant,and respectively:positive ALND 30% vs 53.7% p=0.0001,LVI 13.7% vs 31.6% p=0.0001,PNI 7.2% vs 18.1% p=0.0001,adjuvant chemo 67% vs 85% p=0.0001,adjuvant hormone use 87.3% vs 82% p=0.001.However, recurrence rates did not differ sigificantly among two groups 12% vs 12.6% p=0.4.The median follow-up and DFS time was 48 and 37 months,respectively.Prognostic parameters were also analyzed.Pathologic staging p=0.002,PNI p=0.027,LVI p=0.0001,hormone receptor status p=0.0001,triple negativity p=0.016,luminal A group p=0.048 were found statistically significant on DFS.Diagnosis with mammography was found to have no statistically significant effect on DFS. Conclusions: Although patients diagnosed with mammography had better prognostic parameters,recurrence rates were similar with symptomatic patients at the time of diagnosis.At survival analysis,recurrence rates were calculated to be similar to those of symptomatic patients’ group.

<b><i>Purpose:</i></b> The <i>BRCA1/2</i> gene is the most well-known and studied gene associated with hereditary breast cancer. <i>BRCA1/2</i> genetic testing is widely performed in high-risk patients of hereditary breast cancer in Korea. This study aimed to investigate the clinicopathological characteristics of <i>BRCA1/2</i> mutation-positive breast cancer patients. <b><i>Methods:</i></b> The clinical data of 188 Korean breast cancer patients who underwent genetic testing of <i>BRCA1/2</i> mutation between March 2015 and February 2020 at Pusan National University Yangsan Hospital were retrospectively reviewed. The characteristics of breast cancer according to the expression of <i>BRCA1</i> and <i>BRCA2</i> mutations were analyzed using the Health Insurance Review and Assessment Service guideline criteria and other clinicopathological factors. <b><i>Results:</i></b> The factor associated with <i>BRCA1/2</i> gene expression was cancer stage, and mutation expression was significantly decreased in stage I compared to stage 0 (<i>p</i> = 0.033; odds ratio [OR], 0.169; 95% confidence interval [CI], 0.033–0.867), and there was a tendency to increase in stage II (<i>p</i> = 0.780; OR, 1.150; 95% CI, 0.432–3.064). <i>BRCA1</i> was significantly associated with triple-negative breast cancer (TNBC) (<i>p</i> = 0.004; OR, 5.887; 95% CI, 1.778–19.498). Gene expression of <i>BRCA2</i> was significantly reduced under 40 years of age (<i>p</i> = 0.040; OR, 0.198; 95% CI, 0.042–0.930). There was no difference in disease-free survival (<i>p</i> = 0.900) and overall survival (<i>p</i> = 0.733) between the <i>BRCA1/2</i> mutation-positive and -negative groups. <b><i>Conclusion:</i></b> In this study, the clinicopathological characteristics of breast cancer patients with <i>BRCA1/2</i> gene mutations were identified. <i>BRCA1</i> gene expression was highly correlated with TNBC. <i>BRCA1/2</i> mutation did not have a poor prognosis regarding recurrence and death.

Background: Aberrant of p53 and Bcl2 genes cause changes in the quantity and quality of their proteins and contribute to the pathogenesis of some cancer types including breast cancer. Expression of p53 and Bcl2 were associated to adverse clinical outcomes in breast cancer. Purpose: To predict the survival outcomes of invasive breast cancer in Vietnam, using immunohistochemical expression of p53, Bcl2 proteins. Methods: The current study was conducted on 526 breast cancer patients who had surgical operations, but had not received neo-adjuvant chemotherapy, from 2011 to 2014. The clinicopathological characteristics were recorded. Immunohistochemical staining was performed on p53, Bcl2 markers. Expression of p53 and Bcl2 were paired into different immunophenotypes for analysis with clinicopathological characteristics and survival. All breast cancer patients’ survival were analyzed by using Kaplan-Meier and Log-Rank models. Results: The presence of p53 protein was detected in 44.1%. Positive p53, and p53+Bcl2- immunophenotype were significantly associated with poorer prognostic features. In contrast, the positive Bcl2 protein accounted on 57.6%, and combination of p53-Bcl2+ were strong correlated with better clinicopathological parameters. Bcl2 positivity was observed in higher than the negative Bcl2 in the five-year OS (Overall survival) proportion (91.2 vs 79.4%, respectively) (p < 0.05). Multivariate analysis revealed that the expression of p53, Bcl2 or combinations of these 2 proteins was no longer remained as an independent prognostic variable. Conclusion: The Bcl2 positivity had a distinct OS and DFS (Disease free survival). The expression of p53 and Bcl2 are inversely correlated to clinical outcomes in breast cancer.

Purpose: Older breast cancer patients are underrepresented in cancer research even though the majority (81.4%) of women dying of breast cancer are 55 years and older. Here we study a common phenomenon observed in breast cancer which is a large inter- and intratumor heterogeneity; this poses a tremendous clinical challenge, for example with respect to treatment stratification. To further elucidate genomic instability and tumor heterogeneity in older patients, we analyzed the genetic aberration profiles of 39 breast cancer patients aged 50 years and older (median 67 years) with either short (median 2.4 years) or long survival (median 19 years). The analysis was based on copy number enumeration of eight breast cancer-associated genes using multiplex interphase fluorescence in situ hybridization (miFISH) of single cells, and by targeted next-generation sequencing of 563 cancer-related genes. Results: We detected enormous inter- and intratumor heterogeneity, yet maintenance of common cancer gene mutations and breast cancer specific chromosomal gains and losses. The gain of COX2 was most common (72%), followed by MYC (69%); losses were most prevalent for CDH1 (74%) and TP53 (69%). The degree of intratumor heterogeneity did not correlate with disease outcome. Comparing the miFISH results of diploid with aneuploid tumor samples significant differences were found: aneuploid tumors showed significantly higher average signal numbers, copy number alterations (CNAs) and instability indices. Mutations in PIKC3A were mostly restricted to luminal A tumors. Furthermore, a significant co-occurrence of CNAs of DBC2/MYC, HER2/DBC2 and HER2/TP53 and mutual exclusivity of CNAs of HER2 and PIK3CA mutations and CNAs of CCND1 and PIK3CA mutations were revealed. Conclusion: Our results provide a comprehensive picture of genome instability profiles with a large variety of inter- and intratumor heterogeneity in breast cancer patients aged 50 years and older. In most cases, the distribution of chromosomal aneuploidies was consistent with previous results; however, striking exceptions, such as tumors driven by exclusive loss of chromosomes, were identified.

Screening and adjuvant postoperative therapies have increased survival among women with breast cancer. These tools are seldom applied in elderly patients, although the usually reported incidence of breast cancer is close to 50% in women 65 years or older, reaching 47% after 70 years in the updated Surveillance, Epidemiology, and End Results (SEER) database. Elderly breast cancer patients, even if in good medical health, were frequently excluded from adjuvant clinical trials. Women age 70 years who are fit actually have a median life expectancy of 15.5 years, ie, half of them will live much longer and will remain exposed for enough time to the potentially preventable risks of a relapse and specific death. In the last few years, a new concern about this issue has developed. Treatment now faces two major end points, as in younger women: to improve disease-free survival in the early stages, and to palliate symptoms in advanced disease. However, in both settings, the absolute benefit of treatment is critical because protecting quality of life and all its related aspects (especially functional status and independence), is crucial in older persons who have more limited life expectancy. Furthermore, the new hormonal compounds (aromatase inhibitors) and chemotherapeutic drugs (capecitabine, liposomal doxorubicin), are potentially less toxic than and equally as effective as older more established therapies. These new treatments bring new challenges including higher cost, and defining their benefit in elderly breast cancer must include an analysis of the cost/benefit ratio. These issues emphasize the urgent need to develop and support clinical trials for this older population of breast cancer patients both in the adjuvant and metastatic settings, a move that will take us from a prejudiced, age-based medicine to an evidence-based medicine.

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.
