21002 Background: To explore the hypothesis that ageing alters BC biology, we correlated pt age at diagnosis with biopathological data collected retrospectively from 2723 BC pts treated at the Bordet Institute between 2000 and 2003. Pt's characteristics: Median pts’ age was 56 years old [25–96] and 36% of pt had nodal invasion. Seventy-eight and 63% of the BC were ER+ and PR+ respectively, 33% were grade 3, 24% overexpressed Ki67 (>25%) and 8% were Her2 FISH+. Results: Pts <40 years old had the highest Her2 FISH+ (12%) and hormone-independent (39%) BC rates. More than 50% of the BC were undifferentiated (grade 3) and highly proliferative (Ki67>25%). Moreover, lobular BC were almost absent in young pts (p<.0001); in agreement with the fact that lobular BC were less aggressive than ductal ones (less grade 3, Her2 FISH+ and ER- BC; p<.0001). Hence pts <40 years had a statistically higher rate of “Her2” and “basal-like” BC subtypes. On the contrary, pts >50 years had ‘better prognostic luminal-A” BC with 60% of hormone-dependent BC and a significant drastic decrease of Ki67 expression, tumor grading and Her2 FISH+ (all p=.002). No biological difference was observed between BC of pts >50 years. However, in this group we observed that high ER scores (7–8 vs 3–6) were statistically associated with Her2 FISH- and PR+ characteristics (all p<.0004). Interestingly, the 40–50 years old group which contains 16% of postmenopausal pts, appeared as a transition group according to its biology. Nevertheless, no statistically biological difference could be observed between the BC of pre- and postmenopausal pts. Additionally, when considering the postmenopausal pts from all ages, a clear difference was observed for the different parameters between tumors from pts <50 years compared to older ones (ER, p=.046; grade, p=.0007; Ki67, p=.0001), suggesting that age, and not the menopausal status, is responsible for changes in BC biology Conclusions: BC biology is greatly different in pts before and after the age of 50 but after 50 years old, all pts have BC with similar characteristics. Nevertheless, menopausal status can not account by itself to all these differences and pt ageing appears to have a great impact on BC biology (i.e. Her2 FISH+).

1107 Background: No standart chemotherapy regimen has been estabilished for the treatment of patients with metastatic breast cancer. The gemcitabine and docetaxel combination has been shown to be synergistic . This study is conducted to verify the clinical efficacy and safety of gemcitabine and docetaxel combination therapy in metastatic breast cancer. Methods: 27 metastatic breast cancer patients were treated with gemcitabine-docetaxel combination . Gemcitabine 1,250 mg/m2 IV infusion, on day 1 and 8, and docetaxel 70 mg/m2 on day 1 in 21 day cycles. 4–6 cycles of chemotherapy were repeated every 3 weeks. The primary endpoint was response rate, and survival. Results: The median age was 50 years (range,32–77). Performans status (ECOG) was 0–1. Hormone receptor status: ER+/ER-; 11/16, PR+/PR-; 14/13. Menopausal status were: 11 premenopausal, 16 postmenopausal. Of the 27 evaluable patients, there were 11 (40.7%) partial responses and no complete response. Overall response rate was 40.7%. Median time to progression was 7 months, and median survival was 14 months. Toxicities included grade 3–4 neutropenia in 9 (30%), thrombocytopenia in 6 (22%), anemia in 3(9%). There were no treatment releated deaths Conclusions: The combination of gemcitabine and docetaxel has shown favorable toxicity profile and promising activity in metastatic breast cancer patients.

e12554 Background: ER negative (-)/PgR positive (+) breast cancer (BC) is very uncommon and questioned by many experts. We comprehensively reevaluated ER-/PgR+ BCs in the large cohort from Polish and Hungarian centers. Methods: FFPE blocks from 105 ER-/PgR+ tumors (45 breast biopsies and 64 post-operative samples from tumors not exposed to systemic therapy) were collected from 10 Polish and 3 Hungarian centers. In 60 cases available original slides with ER/PgR staining underwent reevaluation by 3 pathologists (MK, RP, WB) for ER and PgR expression by ASCO/CAP criteria. Subsequently, all samples were stained with 3 antibodies against ER (Dako monoclonal (MC) mouse anti-ERα, clone 1D5; Dako MC rabbit anti-ERα, clone EP1; VENTANA Roche MC rabbit anti-ERα, clone SP1), and PgR (Dako MC mouse anti-PgR, clone 636). If available, > 1 tissue block was used (av. 2.04 blocks/case, range 1-6). In 5 cases ESR1/PGR/ERBB2/MKi67 mRNA was measured by the Xpert® Breast Cancer STRAT4 (Cepheid, Sunnyvale, CA, USA). Results: 13 cases were excluded from immunohistochemical steps of the study due to insufficient amount of tissue and 8 - due to misdiagnosis after ER/PgR reevaluation of original slides. After re-staining, 42 cases (41.5%) retained the original phenotype, in 34 (33.67%) the ER status was corrected to ER+, and 16 (15.84%) tumors were ER/PgR-double-negative. The general agreement between anti-ER clones was moderate (Fleiss’ κ = 0.54). There were 56 ER- and 16 ER+ cases across all three assays. Five cases showed ER positivity with 2 antibodies (either SP1/EP1 or SP1/1D5), 5 tumors reacted exclusively with SP1 clone, and 2 - with 1D5 clone. Xpert Breast Cancer STRAT4 confirmed the ER-/PgR+ phenotype in 4 of 5 analyzed cases. The confirmed ER-/PgR+ BCs were characterized by lower percentage of PgR+ cells (median 5%) than BCs reclassified to ER+ (median 70%) (p = 0.022) and higher Ki67 expression than ER+ cases (median 54.5% vs 25%, respectively; p = 0.003). 39 (92.85%) ER-/PgR+ BCs presented with grade 3. Besides “conventional” high-grade cancers, we identified two distinct morphologies of ER-/PgR+ BC: resembling apocrine carcinoma (n = 5, 11.9%) and carcinoma with central acellular zone (n = 4, 9.5%). Conclusions: ER-/PgR+ BCs confirmed in the current study were defined by high-grade histology, high proliferation index and low percentage of PgR+ cells. We postulate ER-/PgR+ BC is a real albeit rare entity, and its diagnosis should be made cautiously, utilizing retesting with an alternative tissue block and anti-ER antibody.

Abstract Objective To identify the biomarkers of response to neoadjuvant chemotherapy in early luminal breast cancer. Methods A cross-sectional study that included all patients with early or locally-advanced luminal breast cancer submitted to neoadjuvant chemotherapy between 2013 and 2014. Demographic, clinic and pathologic data were retrieved from patient records. The expressions of the estrogen receptor (ER), the progesterone receptor (PR), and Ki67 were analyzed by immunohistochemistry (IHC). The status of the human epidermal growth factor receptor 2 (HER2) was evaluated by IHC and fluorescent in situ hybridization (FISH). Independent predictors of clinic and pathologic response were evaluated by stepwise logistic regression models and receiver operating characteristic (ROC) curve analysis. Results Out of 298 patients identified, 115 were included in the analysis. Clinical complete response (cCR) was observed in 43.4% of the patients (49/113), and pathologic complete response (pCR) was observed in 7.1% (8/115) of the patients. The independent predictors of cCR were premenopausal status (p < 0.001), low PR expression (≤ 50% versus > 50%; p = 0.048), and Ki67 expression ≥ 14% (versus < 14%; p = 0.01). Patients with cCR were more commonly submitted to breast conserving surgery (34.7% versus 7.8%; p < 0.001). Increasing cut-off points for Ki67 expression were associated with an increase in specificity and a decrease in sensitivity to identify patients with cCR. Conclusion Premenopausal status, lower PR expression and higher Ki67 expression were associated with a higher rate of cCR to neoadjuvant chemotherapy in luminal breast cancer.

Abstract Background Molecular classification of breast cancer is an important factor for prognostic and clinical outcomes. There are no data regarding molecular breast cancer subtypes among Togolese women. The objective of this study was to evaluate the expression of ER, PR, HER2, and molecular subtypes of breast cancer receptors in Togolese patients and to establish the correlation between clinical and histological data and molecular types. Methods Clinicopathologic data of patients were collected from clinical records. Immunohistochemistry biomarkers (ER, PR, and HER2) were assessed in patients who have been diagnosed with invasive breast cancer from March 2016 to March 2020 in the department of oncology. The analysis of variance and the Chi-square Test was used to analyze the data. Results A total of 117 cases were collected. The mean age of patients was 52.05 ± 12.38 with an age range of 30 to 85 years. Half of the patients were over 50 years old and the majority (70.9%) was postmenopausal. More than half of patients (52.1%) presented with T3-T4tumors.The most common histologic subtype of breast cancer was invasive ductal carcinoma of no special type (95.7%). Tumors grade 2 were predominant (51.3%) followed by grade 3 (42.7%). Advanced carcinomas were found in 69 patients (59%). The percentage of ER+, PR+, and HER2 positive tumors was 54.7%, 41%, and 15.4% respectively. The predominant molecular subtype was Triple negative (37.6%), followed by Luminal A (30.8.7%), Luminal B subtype (23.9%), and HER2 enriched (7.7%). There was a significant association between stage and breast cancer subtypes (p 0.025), histologic grade, and subtype (p < 0.0001) but no correlation was found with age, menopausal status, and tumor size. Conclusion Breast carcinoma in our patients are high grade tumors and are diagnosed at an advanced stage. Triple negative and Luminal A are the two predominant breast cancer subtypes in Togolese women. Consequently, Receptor testing availability should be a priority to offer the best breast cancer treatment.

e11620 Background: Weight gain is a common and unwanted result of chemotherapy. We wanted to find out how much weight Turkish beast cancer patients gains after chemotherapy and whether it lasts afterwards. Methods: 183 breast cancer patients who underwent a curative resection and received adjuvant chemotherapy afterwards in a private clinic between 1998 and 2007 are studied. Their weight before and after chemotherapy as well as their weight more than a year after chemotherapy is recorded together with their educational level, menopausal status, the type of chemotherapy or hormonal treatment, stage of disease, marital status, occupation and the underlying diseases. Results: Median age of patients is 53 and 72% is in menopause. Educational level is equally distributed for primary education (26%), High school (30%) and University and above (32%). Majority is (76%) married with two children (43%) and house wife (50%). Family history of any cancer is high (33%). Most of the patients had stage II cancer (57%), received anthracycline± taxane based chemotherapy (97%) and has no underlying disease (67%). The majority also does not smoke (72%) or drink alcohol (93%). Mean weight before the chemotherapy was 69.1 and increased to 70.8 upon completion of chemotherapy (p= 0.000) and 72 kg. more than a year after completion of chemotherapy (p=0.000). The other parameters including hormonal treatment, menopause, educational level and smoking do not have any effect on this weight increase. The all groups had similar weight gain with chemotherapy. Conclusions: Although upon starting the study we expected more, we confirmed some amount of weight gain with chemotherapy in Turkish patients and that gain is seen all across various social groups. The doctors should inform their patients of this change and precaution them toward this unwanted consequence. No significant financial relationships to disclose.

e12550 Background: BC is still one of the main causes of death in women due to the tumor recurrence and/or resistance to anticancer therapy. The criteria to assess the effectiveness of BC treatment are important. The purpose of the study was to analyze blood levels of steroid and pituitary hormones in BC patients after two chemotherapy cycles. Methods: The study included 42 patients with various biological BC subtypes: luminal A, luminal B and triple-negative BC (TNBC). Levels of estradiol, testosterone, progesterone, prolactin, LH, FSH and cortisol were measured by RIA in the blood of all patients before and after two neoadjuvant chemotherapy cycles. Significance of differences was evaluated by the Student’s t-test. Results: Levels of many hormones were high before the treatment in patients with all BC subtypes. After two chemotherapy cycles, unidirectional changes in the values were found in patients with subsequent remission for more than three years. Levels of estradiol decreased in luminal A BC by 1.7 times (p˂0.05), in luminal B BC – by 11.6 times (p˂0.05), cortisol decreased by 2.4 and 1.7 times (p˂0.05) respectively, and prolactin – on average by three times (p˂0.05). LH levels increased in luminal A and luminal B BC by 1.65 times (p˂0.05). In patients with TNBC, levels of estradiol decreased by 1.8 times, and cortisol – by two times (p˂0.05). Patients with subsequent remission regardless of BC subtypes had unchanged levels of testosterone, progesterone and FSH. Patients with luminal B and TNBC subtypes with progression in 6-12 months did not show significant changes in prolactin and cortisol levels after two chemotherapy cycles, compared with the values before treatment. Conclusions: A decrease in blood levels of prolactin and cortisol after two chemotherapy cycles is an indicator of a long-term remission in patients with breast cancer.

Vestigial-like 1 (VGLL1) is a poorly characterized gene encoding a transcriptional co-activator structurally homologous toTAZandYAPthat modulates the Hippo pathway inDrosophila. In this study, we examined the expression ofVGLL1and its intronic miRNA, miR-934, in breast cancer.VGLL1and miR-934 expression miRNA profiling was carried out on frozen samples of grade 3 invasive ductal carcinomas. VGLL1 protein was also examined in 433 sporadic andBRCA1-associated breast carcinomas on tissue microarrays. RNA-seq data from The Cancer Genome Atlas (TCGA) was used to confirm differences inVGLL1and miR-934 expression in different breast cancer subtypes, and to correlate their expression with that of other genes and miRNAs. Of 28 miRNAs differentially expressed in estrogen receptor (ER)-positive and ER-negative grade 3 breast carcinomas, miR-934 was most strongly upregulated in ER-negative carcinomas, and its expression was correlated with that ofVGLL1. NuclearVGLL1expression was observed in 13% of sporadic breast carcinomas, and whileVGLL1was only occasionally found in luminal A (0.70%) and B (5.60%) carcinomas, it was often expressed in HER2-positive (17%), triple-negative (TN) breast carcinomas (>40%) andBRCA1-associated TN carcinomas (>50%). These findings were confirmed in the TCGA dataset, which revealed positive associations with luminal progenitor genes (GABRP,SLC6A14,FOXC1,PROM1, andBBOX1) and strong negative correlations with ER-associated genes (ESR1,C6ORF211,GATA3, andFOXA1). Moreover,VGLL1expression was associated with reduced overall survival. In conclusion,VGLL1and miR-934 are mainly expressed in sporadic andBRCA1-associated TN basal-like breast carcinomas, and their coordinated expression, at least partially mediated by the direct modulation ofESR1, might be involved in the maintenance of a luminal progenitor phenotype.

An estimated 1.38 million new cases of breast cancer (BC) are diagnosed each year in women worldwide. Of these, the majority are categorized as invasive ductal cell carcinoma. Subgroups of BC are frequently distinguished into five “intrinsic” subtypes, namely, luminal A, luminal B, normal-like, HER2-positive, and basal-like subtypes. Epidemiological evidence has shown that anthropometric factors are implicated in BC development. Overall consistent positive associations have been observed between high body mass index (BMI) and waist-to-hip ratio (WHR) and the risk of BC among postmenopausal women, while conflicting results persist for premenopausal BC, both for BMI and for other anthropometric parameters as well as across ethnic groups. Furthermore, some evidence suggests that body size, body shape, and weight gain during childhood or adolescence may play a role in the risk of BC. In this paper, we describe the evidence linking anthropometric indices at different ages and BC risk, in order to improve our understanding of the role of body fat distribution in the risk of BC, investigate differences in these associations according to menopausal status and ethnic groups, and discuss the potential biological mechanisms linking body size and BC risk.

Introduction. The omega-3 polyunsaturated fatty acids, as docosahexaenoic acid (DHA), are considered mediators regulating the resolution of inflammation during cancer and may be associated with better outcomes. Epoxydocosapentaenoic acids (EDPs), metabolites of the DHA, are hypothesized to be responsible for some beneficial effects. In the present study, we aimed to assess the circulating 19,20-EDP levels in breast cancer (BC) patients and in healthy controls before and after DHA oral supplementation and the potential differences in the DHA conversion in 19,20-EDPs between patients with different BC presentations. Methods. BC patients and healthy controls were supplemented with DHA (algal oil) for 10 days (2 g/day). Blood samples were collected at baseline (T0) and after supplementation (T1) to assess EDP (19,20-EDP) serum levels by liquid chromatography spectrometry. Results. 33 BC patients and 10 controls were studied. EDP values at T0 were not different between patients and controls. At T1, we found an increase in 19,20-EDP levels in BC patients (P<0.00001) and in controls (P<0.001), whereas no differences in 19,20-EDPs were present between the two groups; when considering the type of BC presentation, patients with BRCA1/2 mutation showed lower 19,20-EDPs levels with respect to BC patients without the mutation (P=0.03). According to immunohistochemical subtype, luminal A-like BC patients showed at T1 higher 19,20-EDP levels compared to nonluminal A (P=0.02). Conclusions. DHA oral supplementation was associated with increased 19,20-EDP serum levels in BC patients, independent of the type of BC presentation, and in controls. Patients carrier of BRCA1/2 mutation seem to possess lower ability of DHA epoxidation, whereas luminal A-like BC patients showed higher EDP conversion. This behavior should be tested in a larger population.
