Summary Objective: To characterize the frequency of HER-2-positive breast cancer in Brazil. Method: In this prospective observational study, we first ascertained the HER-2 status of invasive breast cancer specimens by automated immunohistochemistry (IHC). For specimens classified as 2+ by IHC, we performed in situ hybridization (ISH). Results: From February, 2011 to December, 2012, 1,495 breast specimens were registered, and 1,310 samples collected at 24 centers were analyzed. Median patient age was 54 years, and the majority of samples were obtained from segmental (46.9%) or radical mastectomy (34.4%). The predominant histological type was invasive breast carcinoma of no special type (85%), 64.3% had tubule formation (grade 3), and estrogen/progesterone receptors (ER/PR) were positive in 77.4/67.8% of the specimens analyzed, respectively. Using IHC, we found a negative HER-2 status (0 or 1+) in 72.2% of specimens, and 3+ in 18.5%; the 9.3% scored as 2+ were further analyzed by ISH, of which 15.7% were positive (thus, 20.0% of samples were HER-2- -positive by either method). We found no association between HER-2 scores and menopausal status or histological type. Tumors classified as 3+ came from younger patients, and had higher histological grade and less frequent expression of ER/PR. In the North region of Brazil, 34.7% of samples were 3+, with lower frequencies in the other four regions of the country. Conclusion: Our findings provide estimates for the frequency of HER-2 positivity in Brazil and raise the hypothesis that biological differences may underlie the different distribution of breast-cancer phenotypes among different Brazilian regions.

Estrogen (ER) and progesterone (PgR) receptors were measured simultaneously in 1144 consecutive breast cancer patients to determine the distribution of patients according to receptor and menopausal status when receptor occurrence rates were considered. The prognostic signicance of PgR, either alone or in association with ER, was studied on 187 consecutive breast cancer patients treated only by radical mastectomy. All the cases, as regards axillary node status, were pathologically assessed as node negative. These patients did not receive any adjuvant treatment after mastectomy. At 36 months after mastectomy, the follow-up indicated that PgR- patients have a worse prognosis than PgR+ ones. This is evident when PgR alone is considered as a prognostic factor as well as when it is used to identify, within ER+ cases, those with a higher probability of relapse. In conclusion, it can be stated that although PgR status is an independent prognostic factor, it is useful to evaluate ER and PgR simultaneously for better patient management.

10612 Background: Mafraq hospital is the largest tertiary hospital in UAE. We tested the hypothesis that breast cancer patients in UAE present at a younger age and with more aggressive tumor histology Methods: This is a retrospective study on breast cancer cases seen at Mafraq hospital between 1/00 and 12/05. Intent to treat analysis was used. Total of 372 patients were seen, 48 patients (12.9%) were UAE citizens and 324(87.1%) were non-citizens, 370 females and 2 males. We categorized patients according to their age at time of initial presentation, menopausal status, TNM stage, tumor grade, lymphatic and vascular invasion, ER, PR, Her-2 neu and P53 status. Mode of surgery is also reported. Results: Mean patients age at time of initial presentation is 48 years. 230 (62%) of patients were pre-menopausal and 140 (38%) were post-menopausal. Tumor stages at initial presentation were as follows, stage 0: 7 patients (0.2%), stage I:59 patients (15.9 %), stage II: 180 patients (48.6%), stage III: 71 patients (19.2%) and stage IV: 53 patients (14.3%). Staging was not completed in 2 patients as they followed elesewhere. Vascular invasion was reported in 118 case, 58 (49.2%) were positive and 60 (50.8%) were negative. Lymphatic vessel invasion was reported in 106 case, 84 (79.2%) were positive and 22 (20.8%) were negative. Tumor grades were reported in 265 case and were as follows GI: 33 (12.5%), GII: 121 (45.6%), GIII: 109 (41.1%) and G IV: 2 (0.8%). Tumor hormonal status was reported in 270 case and were as follows: ER+ and PR+ in 94 case (34.8 %), ER+ and PR- in 31 case (11.5%), ER− and PR+ in 25 case (9.3%) and ER− and PR− in 120 case (44.3%). ER and PR were unknown in 102 case. Her2 neu studies were performed in 157 case. Out of those 77 (49%) were positive and 80 (51%) were negative. P53 mutation was studied in 132 patients 33 (25%) were P53 positive and 99 (75%) were P53 negative. 346 patient underwent surgery, 233 patient had modified radical mastectomy and 113 (32.7%) had breast conserving surgery. Conclusions: Breast cancer in UAE tends to occur at a younger age compared to western countries. The majority of our patients are pre-menopausal. Tumors have more aggressive histology and biology. Most tumors show vascular and lymphatic invasion. P53 and Her-2 neu over-expression is relatively high. No significant financial relationships to disclose.

Significant Difference

As age advances, breast cancer (BC) tends to change its biological characteristics. This study aimed to explore the natural progression of such changes. The study included 2383 women with clinically T0-2N0-1M0 BC, managed by primary surgery and optimal adjuvant therapy in a dedicated BC facility. Tissue micro-arrays were constructed from their surgical specimens and indirect immunohistochemistry was used for analysis of a large panel (n = 16) of relevant biomarkers. There were significant changes in the pattern of expression of biomarkers related to luminal (oestrogen receptor (ER), progesterone receptors (PgR), human epidermal growth factor receptor (HER-2), E-cadherin, MUC1, bcl2 CK7/8, CK18 and bcl2) and basal (CK5/6, CK14, p53 and Ki67) phenotypes, lymph node stage, histological grade and pathological size when decade-wise comparison was made (p < 0.05). The ages of 40 years and 70 years appeared to be the milestones marking a change of the pattern. There were significantly higher metastasis free and breast cancer specific survival rates among older women with ER positive tumours while there was no significant difference in the ER negative group according to age. Biological characteristics of BC show a pattern of change with advancing age, where 40 years and 70 years appear as important milestones. The pattern suggests <40 years as the phase with aggressive phenotypes, >70 years as the less aggressive phase and 40–70 years being the transitional phase.

Women undergoing breast conservation therapy (BCT) for stage 1 breast cancer have adjuvant external beam radiotherapy (EBR). In addition, the use of brachytherapy radiation is being used. We present two local tumor recurrences for review. Our first patient underwent BCT, sentinel lymph node biopsy (SLNBx) and MammoSite® brachytherapy for a T1N0M0 infiltrating ductal carcinoma (IDC) of the right breast. Pathology: 0.6 cm poorly differentiated ER, PR, and Her-2/ Neu negative IDC. At 18 months, she had palpable axillary lymph nodes. Fine needle aspiration and ultrasound-guided core biopsy of a nodule showed IDC. She underwent modified radical mastectomy (MRM) and EBR. Our second patient underwent BCT, SLNBx, and MammoSite® brachytherapy for a T1N0M0 IDC of the left breast. Pathology: 0.8 cm poorly differentiated, ER+, PR-, and Her-2/Neu negative tumor. At 18 months, a retroareolar mass was detected. Ultrasound guided core needle biopsy showed recurrent IDC. She chose a re-excision and EBR and not MRM. Pathology: 1.3 cm poorly differentiated, ER+, PR-, and Her-2/Neu negative tumor. Our 2 recurrences were >2 cm away from the lumpectomy site and therefor outside the 1 cm treatment plan of the MammoSite® catheter. Both recurrences were biologically identical to the initial tumors and are felt to be local failures rather than new primaries.

Abstract Background Some endogenous hormones have been associated with breast cancer risk, but the nature of these relationships is not fully understood. Methods UK Biobank was used. Hormone concentrations were measured in serum collected in 2006–2010, and in a repeat subsample (N ~ 5000) in 2012–13. Incident cancers were identified through data linkage. Cox regression models were used, and hazard ratios (HRs) corrected for regression dilution bias. Results Among 30,565 pre-menopausal and 133,294 post-menopausal women, 527 and 2,997, respectively, were diagnosed with invasive breast cancer during a median follow-up of 7.1 years. Cancer risk was positively associated with testosterone in post-menopausal women (HR per 0.5 nmol/L increment: 1.18; 95% CI: 1.14, 1.23) but not in pre-menopausal women (pheterogeneity = 0.03), and with IGF-1 (insulin-like growth factor-1) (HR per 5 nmol/L increment: 1.18; 1.02, 1.35 (pre-menopausal) and 1.07; 1.01, 1.12 (post-menopausal); pheterogeneity = 0.2), and inversely associated with SHBG (sex hormone-binding globulin) (HR per 30 nmol/L increment: 0.96; 0.79, 1.15 (pre-menopausal) and 0.89; 0.84, 0.94 (post-menopausal); pheterogeneity = 0.4). Oestradiol, assessed only in pre-menopausal women, was not associated with risk, but there were study limitations for this hormone. Conclusions This study confirms associations of testosterone, IGF-1 and SHBG with breast cancer risk, with heterogeneity by menopausal status for testosterone.

Background: The aim of this study was to investigate the immunohistochemical expression of ribosomal protein (RP) S6-pS240 in non-special type invasive breast cancer in relation to other prognostic markers and gain new insights to facilitate more individualized treatment. Methods: The following clinical and histopathological parameters of 120 patients were determined: S6-pS240 expression, age, menopausal status, tumor size and grade, TNM stage, Nottingham Prognostic Index (NPI), lymph node stage, estrogen and progesterone receptor (ER/PR) expression, HER2/neu amplification, lymphovascular invasion, and proliferative index as measured by Ki-67. Treatment protocol and disease-free survival were evaluated accordingly. Results: Significant positive correlations were seen between S6-pS240 expression and Ki-67 values (rho = 0.530, p < 0.001), and NPI (rho = 0.370, p < 0.001) and HER2/neu amplification (rho = 0.368, p < 0.001). A negative correlation was found between S6-pS240 and ER/PR expression (rho = 0.362, p < 0.001). Patients with negative RP S6-pS240 expression had significantly longer disease-free survival (log-rank test, p = 0.005). Conclusion: Immunohistochemical analysis of RP S6-pS240 is a valuable additional prognostic marker in patients with invasive breast cancer. Routine use of S6-pS240 immunohistochemistry is recommended.

CONTEXT: Diagnostic staging is an important prognostic factor for endometrial adenocarcinoma. Apart from the histological type and histological grade, some markers seem to be associated with the stage and biological behavior of the disease. Among these are p53, estrogen and progesterone receptors. OBJECTIVE: The objectives of the present study were: to compare histological type and grading of endometrial carcinoma in curettage and hysterectomy samples; to assess expression of p53, estrogen and progesterone receptors in curettage specimens; and to correlate these data with morphology and staging of the disease in hysterectomy specimens. TYPE OF STUDY: Retrospective. SETTING: Department of Pathology, Faculdade de Ciências Médicas, Universidade Estadual de Campinas. SAMPLE: Histological diagnosis from 51 consecutive files. PROCEDURES: Immunohistochemical reactions for p53, estrogen and progesterone receptors via the avidin-biotin-peroxidase method in 51 curettage samples endometrial carcinoma were compared with the morphological data and disease stage in hysterectomy. Marker expression was correlated with histological type and grade and the final stage of the disease. RESULTS: According to the histological type: 44 cases (86%) were of endometrioid and 7 (14%) non-endometrioid carcinoma. p53 expression was observed in 16% of endometrioid and 71% of non-endometrioid cases (p < 0.05). Although estrogen expression was more evident in endometrioid (54%) than non-endometrioid cases (29%), this was not statistically significant. Progesterone receptor expression was significantly higher in endometrioid than non-endometrioid cases (70% vs. 14%, p < 0.05). According to the histological grade: Estrogen and progesterone receptors were expressed more frequently in grade I endometrioid carcinoma, while p53 was mainly reported in tumor grades II and III. According to final disease stage: p53 and estrogen expression in curettage specimens was not related to stage; progesterone receptors, however, were expressed significantly less in advanced disease. CONCLUSION: p53 was observed in the majority of non-endometrioid and in high-grade endometrioid carcinoma, but was not related to stage. Estrogen and progesterone receptors were mainly found in grade I endometrioid carcinoma. The markers studied in curettage were no more valuable for predicting the disease stage than classical histological criteria.
