The objective of the current study was to describe breast cancer cases in men according to age, stage, and histology, calculating risks compared to women. It is a retrospective cross-sectional study of all breast cancer cases of the Hospital Cancer Registry of São Paulo state, Brazil, 2000–2015. Variables were age, sex, stage, and histology. Absolute numbers and proportions, Mann–Whitney test and prevalence ratio with 95% confidence interval were used. The study included 93,737 cases, of which 817 were males. The mean age at diagnosis was 60.3 years in men and 56.2 years in women ( p < .001). Stage II was the most common in both sexes (33.9% in men and 36.5% in women). Men had a higher frequency of stage III than women (PR 1.18, 95% CI 1.01–1.37). Stage 0 was significantly more common in women (PR 0.69, 95% CI 0.51–0.94). Ductal carcinoma and its variants were the most common histological types in both sexes (88.7% in men and 89.0% in women). Men had a higher frequency of rarer histological types such as papillary (PR 2.17, 95% CI 1.36–3.44) and sarcomas (PR 4.10, 95% CI 1.86–9.01). In conclusion, in men, breast cancer diagnosis occurred in more advanced ages and stages. Invasive ductal carcinoma was the primary histological type observed, although rarer types were more frequent.

OBJECTIVE To assess findings of mammography of and interventions resulting from breast cancer screening in women aged 40-49 years with no increased risk (typical risk) of breast cancer. METHODS This cross-sectional study evaluated women aged 40-49 years who underwent mammography screening in a mastology reference center in Recife, PE, Northeastern Brazil, between January 2010 and October 2011. Women with breast-related complaints, positive findings in the physical examination, or high risk of breast cancer were excluded. RESULTS The 1,000 mammograms performed were classified into the following Breast Imaging-Reporting and Data System (BI-RADS) categories BI-RADS 0, 232; BI-RADS 1, 294; BI-RADS 2, 294; BI-RADS 3, 16; BI-RADS 4A, 2; BI-RADS 5, 1. There was one case of grade II invasive ductal carcinoma and various interventions, including 469 ultrasound scans, 53 referrals to mastologists, 11 cytological examinations, and 8 biopsies. CONCLUSIONS Mammography screening in women aged 40-49 years with typical risk of breast cancer led to the performance of other interventions. However, it also resulted in increased costs without demonstrable efficacy in decreasing mortality.

Introduction: Some unique physiological changes occur in breast volume and water content during pregnancy which makes the radiological evaluation of the breast difficult.  As a result, diagnosis of Pregnancy Associated Breast Cancer.  is often delayed. Objective: To find out the diagnostic accuracy of ultrasonography in detection of pregnancy associated breast cancer taking histopathology as gold standard. Methodology: Present Cross-sectional study was carried out at INMOL Hospital, Lahore. Ultrasound of 200 women was performed. The patient was laid supine and then turned slightly in oblique position to scan the breast with high frequency linear probe (7.5-10 MHz). The contra-lateral breast and both axillae were also scanned in the same way. Findings were categorized on the basis of Breast Imaging Reporting and Data System (BI-RADS) assessment categories. Subsequently the breast tissue was sent to histopathology laboratory for tissue diagnosis. The pathologist was blinded of the results of ultrasonography. Results: Mean age was 34 ± 11.36 years. Twenty-eight percent patients were primi-para while 72% patients were multi-para. Diagnostic accuracy of ultrasonography taking histopathology as gold standard was analyzed and ultrasonography had sensitivity 84.78%, specificity 98.05%, positive predictive value 92.85%, negative predictive value 95.56% and diagnostic accuracy was 95%. Invasive ductal carcinoma was most commonly observed (P<0.001) malignant histopathology. On the other hand, significantly high (P = 0.033) number of benign lesions were Fibroadenomas. Conclusion: The high sensitivity and specificity along with easy availability, and non-invasive nature makes ultrasonography a very useful technique for the diagnosis of Pregnancy Associated Breast Cancer.

Abstract Background Screening of breast cancer in asymptomatic women is important to evaluate for early diagnosis. In China ultrasound is a more frequently used method than mammography for the detection of breast cancer. The objectives of the study were to provide evidence and assessment of parenchymal patterns of ultrasonography for breast cancer detection among Chinese women. Methods Breast ultrasound examinations including the parenchymatous pattern of cytopathological confirmed breast cancer (n = 541) and age-matched cytopathological not confirmed breast cancer (n = 849) women were retrospectively reviewed by seven sonographer physicians. According to compositions of ducts, the thickness of the breast, diameter of ducts, fat lobules, and fibro glandular tissues, the breast parenchymatous pattern was categorized into heterogeneous (high percentage of fatty tissues), ductal (the inner diameters of ducts > 50% of the thick mass of the breast), mixed (the inner diameters of ducts was 50% of the thick mass of the breast), and fibrous categories (a dense classification of the breast). Results Heterogeneous (p < 0.0001, OR = 3.972) and fibrous categories (p < 0.0001, OR = 2.702) were higher among women who have cytopathological confirmed breast cancer than those who have not cytopathological confirmed breast cancer. The heterogeneous category was high-risk ultrasonographic examination category followed by the fibrous category. Agreements between sonographer physicians for categories of ultrasonic examinations were fair to good (Cohen’s k = 0.591). Conclusions Breast cancer risk in Chinese asymptomatic women differ according to the ultrasonographic breast parenchymal pattern. Level of Evidence: III. Technical efficacy stage: 2.

Abstract Breast cancer is the most frequent in women, resulting in fatigue and depressive symptoms as consequence of treatment, but physical activity can help in this process. The aim of this study was to investigate the relationship between fatigue, depressive symptoms and practice of physical activity of women with breast cancer during treatment or after cancer treatment. This is a cross-sectional study with 179 women (56.89 ± 9.4 years) from the Oncology Research Center - CEPON, using questionnaire on general and clinical information, fatigue (Piper Fatigue Scale) depressive symptoms (Beck Depression Inventory) and physical activity (IPAQ - short version). Women with moderate to severe fatigue underwent physiotherapy (p = 0.001) and women with no fatigue had minimum depressive symptoms (p ?0.001). Level of physical activity was not associated with fatigue, with most women being insufficiently active and women with mild fatigue had longer walking time than those without fatigue (p = 0.049). Women with depressive symptoms were almost three times more likely of having mild to severe fatigue and those who underwent physiotherapy were twice as likely of having mild to severe fatigue. Women with fatigue had greater presence of depressive symptoms. Professionals working in the field of oncology should recommend the practice of physical activity in order to minimize the side effects of treatment and observe depressive symptoms and fatigue in these women.

Diffuse optical spectroscopy is a relatively new, noninvasive and nonionizing technique for breast cancer diagnosis. In the present study, we have introduced a novel handheld diffuse optical breast scan (DOB-Scan) probe to measure optical properties of the breast in vivo and create functional and compositional images of the tissue. In addition, the probe gives more information about breast tissue’s constituents, which helps distinguish a healthy and cancerous tissue. Two symmetrical light sources, each including four different wavelengths, are used to illuminate the breast tissue. A high-resolution linear array detector measures the intensity of the back-scattered photons at different radial destinations from the illumination sources on the surface of the breast tissue, and a unique image reconstruction algorithm is used to create four cross-sectional images for four different wavelengths. Different from fiber optic-based illumination techniques, the proposed method in this paper integrates multi-wavelength light-emitting diodes to act as pencil beam sources into a scattering medium like breast tissue. This unique design and its compact structure reduce the complexity, size and cost of a potential probe. Although the introduced technique miniaturizes the probe, this study points to the reliability of this technique in the phantom study and clinical breast imaging. We have received ethical approval to test the DOB-Scan probe on patients and we are currently testing the DOB-Scan probe on subjects who are diagnosed with breast cancer.

Training Approach

This research presents a breast cancer detection system using deep learning method. Breast cancer detection in a large slide of biopsy image is a hard task because it needs manual observation by a pathologist to find the malignant region. The deep learning model used in this research is made up of multiple layers of the residual convolutional neural network, and instead of using another type of classifier, a multilayer neural network was used as the classifier and stacked together and trained using end-to-end training approach. The system is trained using invasive ductal carcinoma dataset from the Hospital of the University of Pennsylvania and The Cancer Institute of New Jersey. From this dataset, 80% and 20% were randomly sampled and used as training and testing data respectively. Training a neural network on an imbalanced dataset is quite challenging. Weighted loss function was used as the objective function to tackle this problem. We achieve 78.26% and 78.03% for Recall and F1-Score metrics, respectively which are an improvement compared to the previous approach.

Place and Duration of Study: Histopathology department, Armed Forces Institute of Pathology Rawalpindi, form Jan to Jun 2019. Methodology: Sixty five cases of breast cancer were retrieved. Clinicopathological parameters like age, gender,tumor grade and receptor status were noted. Immunohistochemistry for PD-1 and PD-L1 was applied. The datawas entered and statistical analysis was done using SPSS version 21. The associations between variables werefound using the Fisher exact test. Results: Sixty five cases of breast cancer were investigated from tumour registry. The sample included femalepatients, having mean age of 50.86 ± 11.1 Years. Invasive mammary (ductal) carcinoma, NST was the most prevalent subtype 60 (92.3%) and most tumors were grade I/II 53(82%). PD-1 expression was seen in TIL’s 31 (48%) and PD-L1 expression was observed in tumour cells 30 (46%). Expression of PD-1/PD-L1 expression was more common in premenopausal age group and grade I/II tumors. Among molecular subtypes, PD-L1 expression was detected in 11 (52%) TNBC, 5 (71%) in HR-/HER2+ and 12 (32)% in HR + HER2 - and PD-1 expression was observed in 13 (62%) TNBC, 5 (71%) in HR-/HER2+ and 13 (35%) in HR+ HER2-. Conclusion: A large proportion of breast cancer cases show expression of PD-1 / PD-L1. Anti PD-1 and PD-L1therapy may benefit these patients.
