Breast cancer continues to remain the most lethal malignancy in women across the world. This study reviews some of the epidemiological similarities and differences in breast cancer between white European women and black African women with the aim of optimising care for women with breast malignancy across the world. The incidence of breast cancer is lower among African women than their European counterparts. Majority of women in Europe are postmenopausal when they present with breast cancer; however, the peak incidence among African women is in the premenopausal period. Ductal carcinoma is the commonest type of breast cancer among women in Africa and Europe. However, medullary and mucinous carcinomas are more common in Africa than in Europe. While European women usually present at an early stage especially with the advent of screening, African women generally present late for treatment resulting in lower survival rates. There should be more research at the molecular level among African women to identify genetic factors that may contribute to the risk of developing breast cancer. There should also be improvement in the health care system in Africa in order to optimise care for women with breast cancer.

Background: Breast cancer is today a global health problem. With 1,671,149 new cases diagnosed in 2012, it is the most common female cancer in the world and accounts for 11.9% of all cancers and it affects more people than prostate cancer. In 2008, The United States statistics showed that, for all cancer that affect women before 40 years, more than 40% of them concerned the breast. The aim of this study was to describe the clinical, histopathological and therapeutic aspects of breast cancer in women under 40 years of age in Yaoundé.Methods: This was a retrospective study with data collected from 192 medical case files of women treated over a period of 12 years, from January 2004 to December 2015 at the Yaounde General Hospital and the Yaounde Gyneco-Obstetric and Pediatric Hospital. Microsoft Epi Info version 3.4.5 and SPSS version 20.0 softwares were used for data analysis.Results: From 2004 to 2015, 1489 cases of breast cancer were treated in both hospitals. Of these, 462 women were less than 40 years old, representing a proportion of 31.0%. The mean age at diagnosis was 33.5±5.0 years and 17.7% of women had a family history of breast cancer. The average time before an initial consultation was 6.7±6.6 months.  Most cases were classified as T4 (46.1%). The most common histological type was ductal carcinoma (87.4%). Grades SBR II and SBR III were predominant (76.4%). Axillary dissection (64.4%) and neoadjuvant chemotherapy (43.9%) were the main therapeutic modalities. The overall survival rate at 5 years was 51.2%. Five-year survival rates with no local recurrence and no metastatic occurrence were 35.8% and 43.2% respectively.Conclusions: Breast cancer largely affects women under the age of 40 and is often discovered late, at an advanced stage. The prognosis appears poor. Only screening could facilitate diagnosis at an early stage of the disease for better outcomes.

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.

Aims and background Often neglected by large clinical trials, patients with uncommon breast malignancies have been rarely analyzed in large series. Patients and methods Of 2,052 patients diagnosed with breast cancer and followed in our Institution from January 1985 to December 2009, we retrospectively collected data on those with uncommon histotypes, with the aim of investigating their presentation characteristics and treatment outcome. Results Rare histotypes were identified in 146 patients (7.1% of our total breast cancer population), being classified as follows: tubular carcinoma in 75 (51.4%), mucinous carcinoma in 36 (24.7%), medullary carcinoma in 25 (17.1%) and papillary carcinoma in 10 patients (6.8%). Whereas age at diagnosis was not significantly different among the diverse diagnostic groups, patients with medullary and papillary subtypes had a higher rate of lymph node involvement, similar to that of invasive ductal carcinoma. Early stage diagnosis was frequent, except for medullary carcinoma. Overall, in comparison with our invasive ductal carcinoma patients, those with rare histotypes showed a significantly lower risk of recurrence, with a hazard ratio of 0.28 (95% CI, 0.12–0.62; P = 0.002). Conclusions According to our analysis, patients with uncommon breast malignancies are often diagnosed at an early stage, resulting in a good prognosis with standard treatment.

ObjectiveTo use newly available self-assigned ethnicity information to investigate variation in breast cancer screening uptake for women from the 16 specific ethnic groups within the broad Asian, Black and White groups that previous studies report.SettingNational cancer screening programme services within London.Participants655 516 female residents aged 50–69, invited for screening between March 2006 and December 2009. Ethnicity information was available for 475 478 (72.5%). White British women were the largest group (306 689, 46.8%), followed by Indian (34 687, 5.3%), White Other (30 053, 4.6%), Black Caribbean (25 607, 3.9%), White Irish (17 271, 2.6%), Black African (17 071, 2.6%) and Asian Other (10 579, 1.6%).Outcome measuresUptake for women in different ethnic groups aged 50–52 for a first call invitation to the programme, and for women aged 50–69 for a routine recall invitation after a previous mammography. Uptake is reported (1) for London overall, adjusted using logistic regression, for age at invitation, socioeconomic deprivation and geographical screening area, and (2) for individual areas, adjusted for age and deprivation.ResultsWhite British women attended their first call (67%) and routine recall (78%) invitations most often. Indian women were more likely to attend their first (61%) or routine recall (74%) than Bangladeshi women (43% and 61%, respectively), and Black Caribbean women were more likely than Black African women to attend first call (63% vs 49%, respectively) and routine recall (74% vs 64%, respectively). There was less variation between ethnic groups in some screening areas.ConclusionsBreast cancer screening uptake in London varies by specific ethnic group for first and subsequent invitations, with White British women being more likely to attend. The variation in the uptake for women from the same ethnic groups in different geographical areas suggests that collaboration about the successful engagement of services with different communities could improve uptake for all women.

Abstract Background and objective Currently no definite guideline exists on the use of intraoperative radiation therapy (IORT) among patients with early stage BC. We report our experiences with IORT among breast cancer (BC) patients in our region.Methods All patient who received radical IORT from April 2014 on to March 2020 were included in the study. Patient selection criteria were as followed: age equal or older than 45 years old; all cases of invasive carcinomas, moreover in lobular carcinomas only after MRI and confirmation, and in cases with ductal carcinoma in-situ (DCIS) only those with low, intermediate grade, tumor size of equal or less than 2.5cm and a margin of 2-3mm; those between 45 and 50 years old with a tumor size of 0-2cm, those between 50 and 55 years old with a tumor size of 2-2.5cm, and those ≥55 years old with a tumor size of 2.5-3cm; those with invasive tumors a negative margin and in cases of DCIS a margin of 3mm; a negative nodal status (exception in patients with micrometastasis); and a positive estrogen receptor status. Results Overall, 252 patients entered the study. Mean (SD) age of patients was 56.43±7.79 years. In total, 32.9% of patients had a family history of BC. Mean tumor size was 1.56±0.55 cm. Median (IQR) follow-up of patients was 24 (13, 36) months. Overall, 6 patients (2.4%) experienced recurrence in follow-up visits, among which three (1.2%) were local recurrence, two (0.8%) were regional recurrence and one patients (0.4%) had metastasis.Median (IQR) time to recurrence was 23 (13, 36) among the six patient who had recurrence. Overall, 11 patients (4.3%) with DCIS in our study received IORT. All these patients had free margins in histopathology examination. None of these patients experience recurrence.Conclusion For the first time, we categorized patients according to age and tumor size and older patients with larger tumor sizes were considered appropriate candidates for IORT. Our series showed a successful experience with the use of IORT in a region where facilities for IORT are limited using our modified criteria for patient selection.

AbstractOncologic therapy is currently undergoing significant changes. A number of innovative targeted medications currently in clinical development have raised high expectations. With that in mind, discussions about terms such as “clinical benefit” and “clinical relevance” are highly topical. This also applies to further developments in the field of adjuvant systemic therapies for early-stage breast cancer. As the treatment aim is curative, assessment of the clinical benefit of adjuvant therapies must be largely based on efficacy outcomes. The focus must be on improving disease-free survival rates and lowering the risk of recurrence. Because of the current low mortality rates, statements about overall survival rates are only possible after very long observation periods. Consequently, new drugs in adjuvant therapies should be considered as offering a clinical benefit, if they reduce the risk of recurrence below current low levels of risk. The evidence for established adjuvant therapy standards in early-stage breast cancer can be used as objective criteria for comparison. This review article considers the requirements for clinical benefit of new adjuvant therapies for early breast cancer, based on examples from adjuvant endocrine therapy, adjuvant polychemotherapy and adjuvant anti-HER2 therapy.

PURPOSE To assess the frequency and prognosis of skin recurrences after breast-conserving therapy (BCT) compared with other breast recurrences. MATERIALS AND METHODS From 1968 to 1986, 1,624 patients with unilateral stage I or II breast cancer treated with BCT at the Joint Center for Radiation Therapy (Boston, MA) underwent gross tumor excision and received a dose of > or = 60 Gy to the tumor bed. Skin recurrences (SR) were defined as breast recurrences without associated parenchymal disease. An invasive breast recurrence with any parenchymal disease noted clinically or radiographically was scored as an other breast recurrence (OBR). Median follow-up for survivors was 137 months. RESULTS SR represented 8% (18 of 229) of all breast recurrences and occurred in 1.1% of all patients. The outcome after local recurrence was different for patients with SR and invasive OBR. Patients with SR more frequently had uncontrolled local failure (50%; 9 of 18) than did patients with OBR (14%; 26 of 188) (P = .0007). Forty-four percent (8 of 18) of patients with SR had distant metastasis simultaneously or within 2 months of the recurrence compared with 5% (9 of 188) of invasive OBR patients (P < .0001). For patients without distant metastasis at the time of recurrence, the 5-year actuarial rate of development of distant metastasis was 60% for SR patients compared with 39% for invasive OBR patients (P = .07), and the corresponding 5-year actuarial survival rates beyond the time of local failure were 51% and 79%, respectively (P = .06). CONCLUSION In contrast to other types of invasive breast recurrence after breast-conserving therapy, skin recurrences are rare and are associated with a significantly higher rate of distant metastasis and uncontrolled local disease as well as a lower rate of survival.

587 Background: The incidence of MBC continues to rise. Few studies have addressed the differences between MBC and female breast cancer (FBC). Treatment for MBC has ben extrapolated from FBC regimens. The VA cancer registry (VACCR) provides a unique source to study MBC. This retrospective analysis aims at comparing the characteristics and outcome of MBC and FBC in the VA population. Methods: We reviewed the VACCR database between 1995 and 2005, for 120 VA medical centers. Primary breast cancer site codes were identified (500–508). Data was entered and analyzed using bio-statistical software SPSS. Results: A total of 3025 patients :612 MBC and 2413 FBC were compared. Mean age at diagnosis was 67 for MBC and 57 for FBC (p <0.005). More MBC patients were black. MBC patients presented with a significantly higher stage of disease, more node positive(N+) and larger tumor size. In MBC, ductal histology was more common while lobular and ductal carcinoma in situ were less common than in FBC. ER + and PR + tumors were significantly more common in MBC (60% vs 52% and 53% vs 47%, P< 0.005). MBC patients received less chemotherapy while no statistical difference in hormonal treatment was observed. The median overall survival (OS) was lower for MBC (7 years vs 9.8 years, p<0.005). OS was not significantly different for stage III and IV while OS was inferior for MBC in stage I (7 yr vs not reached, p 0.005) and stage II (6 vs 8.6yr, p 0.001). In N- tumors, OS was inferior in MBC (6.1 vs 14.6 yr, p<0.005) but not statistically different for N+ tumors . In ER + and PR + tumors, OS was inferior in MBC (7yr vs 8yr and 7.3 yr vs 9.8 yr p<0.005); however, no statistical significance was observed in ER - or PR - tumors. Using Cox regression analysis age, sex, clinical stage, nodal status were statistically independent prognostic factors while race, histology and grade were not. Conclusion: This study suggests differences in the biology, pathology, presentation, and survival between male and female VA breast cancer patients. Survival of MBC patients appears inferior in early stage disease and N- tumors suggesting gender differences in the tumor pathogenesis and biology. In hormone receptor + MBC, survival was also inferior despite similar hormonal treatment practices. This observational study calls for different approach and treatment strategies in MBC.

e11630 Introduction: Male breast cancer is very rare, representing only between 0.7% and 1% of all breast cancers, and only half of them are early stage cases. Objective: The present study has been designed with the aim of studying retrospectively the clinical onset and evolution of male invasive breast cancer patients (stages I and II) treated at IOHM between 1997 and 2008. Methods: The records of 3,000 breast cancer cases followed between 1997 and 2008 were searched, looking for male stage I and II breast cancer patients. A database was designed following the recommendations of the Directors of Surgical Pathology of the USA. The information registered encompassed: adjuvant treatments, recurrence date and date of final consultation or death. Results: Twelve pts were identified. Mean age (range)= 66 yo (50–89 yo). Tumoral type= Invasive Ductal Carcinoma 12 pt. Tumoral subtype= NOS 9 pt (75%) Apocrine 2 pt (17%) Micropapillar 1 pt (8%). Nottingham´s grade= Grade 2: 8 pt, Grade 3: 3 pt, N/A=1 pt. Stage= I= 6 pt, II=6 pt. ER (Positve= 9 pt, Negative=1 pt, N/A= 2 pt). PR (Positve= 8 pt, Negative= 2 pt, N/A=2 pt). Her2neu (0+= 3 pt, 1+= 3 pt, 2+= 2 pt, N/A= 4 pt). Surgery= Mastectomy= 11 pt, Lumpectomy 1= pt. Radiotherapy=5 pt. Adjuvance= No=2 pt, Hormonotherapy (HT)= 3 pt, Chemotherapy (CHT) = 3 pt, CHT+HT= 4 pt. Recurrence= Yes= 2 pt, No= 10 pt. Survival: Dead= 1 pt, Alive =11 pt. Mean Time To Progression= Stage I =66 months, Stage II =42 months. Global survival: Stage I =66 months, Stage II =52 months. Conclusions: 1. Twelve stage I and II male breast cancer patients were identified out of 3000 (0.4%) breast cancer cases diagnosed and followed in the past 10 years at the IOHM. 2. Mastectomy was the surgical procedure in 11 of the 12 cases 3. Ten pt underwent adjuvant treatment. 4. With a mean follow up time of 60 months, all stage I patients are alive and there were no recurrences. Two of the 6 stage II pts progressed and one died.
