Abstract
INTRODUCTION Male breast cancer accounts for 1% of all breast cancers. Its low frequency leads to a lack of awareness, resulting in significant diagnostic delays. Additionally, this limits the available evidence, which primarily uses diagnostic-therapeutic algorithms based on women. OBJECTIVES To analyze the prevalence, clinical presentation, anatomical and pathological characteristics, and prognosis of male breast cancer using one of the largest series available. Secondarily, to compare our data with studies conducted in women. MATERIALS AND METHODS A multicenter, observational, descriptive, retrospective study was conducted in the autonomous community of Aragon, Spain, from 1995 to 2022 including men with a pathological diagnosis of breast cancer. RESULTS A total of 148 patients were included, with a prevalence of 1%. The most common clinical presentation was a palpable retroareolar mass. Invasive ductal carcinoma was the most frequent type (88.89%), and luminal B was the predominant subtype (47.76%). Surgery was the most utilized treatment; mastectomy was performed in 90.34% and AL in 46.89%. At diagnosis, 52.46% had extramammary involvement. The recurrence rate was 24.1%, and the mortality attributed to the disease was 14.6%. CONCLUSIONS There is a high rate of metastatic involvement at diagnosis, a high percentage of mutilating surgeries, and a high number of recurrences compared to available studies on males. Additionally, a worse prognosis is observed compared to breast cancer in women, despite these tumors having a less aggressive molecular subtype. These findings highlight the importance of conducting studies focused on men to develop specific protocols.

Abstract
BACKGROUND Neuroendocrine neoplasms (NENs) are increasing in incidence globally. Previous analysis of the UK cancer database (National Cancer Registration and Analysis Service (NCRAS)) showed a notable female survival advantage in most tumour sites. This study aims to compare NCRAS to the Surveillance, Epidemiology, and End Results Program (SEER) to validate these results using the same statistical methods. METHODS A total of 14,834 and 108,399 patients with NENs were extracted from NCRAS and SEER, respectively. Sixty-months survival for both males and females for each anatomical site of NENs were calculated using restricted mean survival time (RMST) and Kaplan-Meier Survival estimates. The sixty-month RMST female survival advantage (FSA) was calculated. RESULTS FSA was similar in NCRAS and SEER. The highest FSA occurred in lung and stomach NENs. CONCLUSIONS The data from SEER confirm the findings published by NCRAS. Female survival advantage remains unexplained.

Accuracy of sentinel lymph node biopsy in male breast cancer: Systematic review and meta-analysis. Breast 2024; 75:103703. [PMID: 38461570 PMCID: PMC10940173 DOI: 10.1016/j.breast.2024.103703] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/21/2023] [Revised: 02/25/2024] [Accepted: 02/27/2024] [Indexed: 03/12/2024] Open
Abstract
BACKGROUND Sentinel lymph node biopsy (SLNB) is commonly used in the surgical management of male breast cancer. Contrary to female breast cancer, limited data exist about its performance in male breast cancer. The objective of this systematic review and meta-analysis was to evaluate the SLNB accuracy in male breast cancer. METHODS MEDLINE, EMBASE, Web of Science and The Cochrane Library were searched from January 1995 to April 2023 for studies evaluating the SLNB identification rate and false-negative rate in male breast cancer with negative preoperative axillary evaluation and primary surgery. For SLNB false-negative rate, the gold standard was the histology of axillary lymph node dissection (ALDN). Methodological quality was assessed by using the QUADAS-2 tool. Pooled estimates of the SLNB identification rate and false-negative rate were calculated. Heterogeneity of the pooled studies was evaluated using I2 index. RESULTS A total of 12 retrospective studies were included. The 12 studies that reported the SLNB identification rate gathered a total of 164 patients; the 5 studies that reported the SLNB false-negative rate gathered a total of 50 patients with a systematic ALND. The pooled estimate of the SLNB identification rate was 99.0%. The SLNB false-negative rates were 0% in the 5 included studies and consequently so as the pooled estimate of the false-negative rate with no heterogeneity. CONCLUSION SLNB for male breast cancer, following negative preoperative axillary assessment and primary surgery, appears feasible, consistent, and effective. Our research supports conducting immediate SLNB histological evaluation to facilitate prompt ALND in case of positive results.

Abstract
BACKGROUND Following the positive iDFS and OS results of the phase III clinical trials monarchE, NATALEE and OlympiA, new oral anticancer agents (the CDK4/6 inhibitors abemaciclib, ribociclib as well as the PARP inhibitor olaparib) have recently been introduced into the treatment of high-risk early breast cancer (eBC). However, only few male patients were included in these trials (0.4%, 0.6% and 0.3%, respectively). The objective of this real-world analysis was to determine the proportion of male patients with eBC fulfilling the clinical high-risk criteria of above-mentioned trials. PATIENTS AND METHODS We conducted a data inquiry and analysis with the Cancer Registry of Baden-Württemberg of men with breast cancer diagnosed between January 1, 2015 and December 31, 2021. Men with eBC were identified and the number of patients at clinical high-risk according to the inclusion criteria of monarchE, NATALEE and OlympiA was assessed. RESULTS Of 397 men with eBC, 354 (89.1%) had a HR + /Her2- and 4 (1.0%) a triple-negative subtype. 84 patients (21.2%) met the clinical high-risk criteria according to the monarchE, 189 (47.6%) those according to the NATALEE and 50 (12.6%) those according to the OlympiA trial. CONCLUSION In a large real-world sample, more men with eBC are at clinical high risk according to the inclusion criteria of monarchE, NATALEE and OlympiA than would be expected in women. This is most likely due to more advanced stages at initial diagnosis in men. To evaluate whether CDK4/6 and PARP inhibitors improve prognosis also in men should be the topic of future real- world analyses.

Ocul Surf 2024; 34:1-8. [PMID: 38821405 DOI: 10.1016/j.jtos.2024.05.002] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/18/2024] [Revised: 05/03/2024] [Accepted: 05/23/2024] [Indexed: 06/02/2024]
Abstract
PURPOSE To investigate the delayed diagnosis of chronic ocular graft-versus-host disease (coGVHD) after allogeneic hematopoietic stem cell transplantation (alloHCT), and further analyze potential confounding factors. METHODS This cross-sectional study included 118 patients newly diagnosed as coGVHD after alloHCT at Zhongshan Ophthalmic Center, Sun Yat-sen University. All participants finished the flow path of medical history taking, detailed ophthalmological examination and questionnaire-based survey. coGVHD was diagnosed and graded by International Chronic Ocular GVHD Consensus Group (ICOGCG) criteria. Lag time of diagnosis was defined as interval between noting of ocular symptoms and confirmed diagnosis of coGVHD (TN-D). We further compared the clinical parameters between groups categorized by the median TN-D as medium and long delay groups. RESULTS The median TN-D was 6.3 [IQR 2.8-14.5] months. Most coGVHD patients underwent delayed diagnosis of coGVHD longer than 3 months (70 %, 83 of 118), with 90 of 118 diagnosed as severe coGVHD (76 %). The long delay group exhibited higher ICOGCG scores (10 [IQR 9-10.5] vs. 9 [IQR 8-10], P = 0.039) and more pronounced ocular signs, including conjunctival injection, meibomian gland loss, fibrotic tarsal conjunctiva, symblepharon, and corneal complications (all P < 0.05). Delayed diagnosis was strikingly correlated with seeking ophthalmic medical care twice or more prior to diagnosis (adjusted OR = 5.42, 95%CI: 1.40-21.06, P = 0.015) and accurate knowledge of ocular discomfort symptoms in coGVHD (adjusted OR = 0.29, 95%CI: 0.08-1.00, P = 0.050). CONCLUSIONS Delayed diagnosis of coGVHD, associated with disease severity, was common among alloHCT recipients in southern China. Improving patient education and the awareness of ophthalmologists may facilitate early diagnosis of coGVHD.

Abstract
How cancer patterns in humans compare to those of other species remains largely unknown and there is an even bigger knowledge gap for rare cancers like male breast cancer. One Health is a convergence of human and animal healthcare that encourages cross-pollination of medical research uniting human and veterinary medicine. Recognising that breast cancer occurs spontaneously in other male species (e.g. primates, canines, felines), and knowing that no laboratory models exist for male breast cancer, which limits our ability to perform functional studies, we explored the feasibility of applying One Health to breast cancer in men by conducting a narrative review of the topic. Spontaneous development of breast cancer was reported in captive male primates and in companion canines and felines. Some parallels in tumour biology of human male breast cancer with canines and primates were found. The age distribution, pattern of biomarker expression and metastasis were similar, with mammary tumours typically detected after two-thirds of average lifespan. However, instances of triple negative and inflammatory breast cancer, which are rarely observed in human male breast cancer, were found in canines and histological classification was inconsistent between species. These disparities need redressing to enable full exploration of the One Health paradigm in rare cancers.

Abstract
Breast cancer in men represents approximately 1% of all breast cancer diagnoses. Among all patients with breast cancer, approximately 30% will develop brain metastases. Over the past decade, there have been multiple advances in the treatment of metastatic breast cancer; however, long-term outcomes of this presentation in male patients are lacking. We evaluated male patients with de novo stage IV breast cancer using the Surveillance, Epidemiology and End Results (SEER) database from 2010 to 2019. Overall survival (OS) was estimated using the Kaplan-Meier method and differences between groups were compared using log rank tests. In total, 22 male patients with brain metastases at initial breast cancer diagnosis were included. Patients with HR-positive/HER2-negative tumors had the longest OS (median 13 months). Factors associated with shorter overall survival were advanced age, unmarried marital status, lower household income, and grade III disease, among others. Brain metastases remains an unmet medical need for patients with breast cancer; the development of new drugs may provide an improvement in overall survival for male patients in the future.

Abstract
This report documents the case of a 36-year-old female diagnosed with stage I invasive ductal carcinoma of the left breast who, alongside her 39-year-old husband, sought fertility assistance at our center due to primary infertility. Having survived cancer twice in the span of their seven-year marriage, the couple faced the challenge of overcoming both the repercussions of cancer treatment and difficulties in conceiving. Initial attempts through three intrauterine insemination (IUI) cycles proved unsuccessful, leading the couple to opt for in vitro fertilization (IVF). The fertility assessment of the husband revealed the presence of several pus cells and a high sperm DNA fragmentation index (DFI). To address this, a medication regimen was administered to improve sperm quality. Concurrently, the female underwent controlled ovarian stimulation (COS) with the anti-estrogen agent letrozole to mitigate the risk of estrogen surges that could compromise her health. Subsequently, oocytes were retrieved from the female, and intracytoplasmic sperm injection (ICSI) was used to facilitate fertilization with her husband's sperm. Following successful embryo development, the patient underwent embryo transfer (ET), resulting in a positive beta-human chorionic gonadotropin (beta-hCG) result, signifying a successful conception. This case report highlights the intricate challenges faced by individuals with a history of breast cancer, emphasizing the delicate balance required in managing infertility in such circumstances. The described approach, involving personalized treatments and meticulous care, underscores the possibility of achieving successful conception for females struggling with fertility issues post-cancer survival. The documented journey serves as a testament to the resilience of individuals facing the dual challenges of cancer survival and infertility, offering insights into the complexities of their reproductive healthcare.

Nationwide Analysis of Locoregional Management for Ductal Carcinoma In Situ in Males: An NCDB Analysis of the Surgical Approach to DCIS in Males. Ann Surg Oncol 2024; 31:1599-1607. [PMID: 37978114 DOI: 10.1245/s10434-023-14579-w] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/08/2023] [Accepted: 10/25/2023] [Indexed: 11/19/2023]
Abstract
BACKGROUND Limited data exist regarding the optimal locoregional approach for males with ductal carcinoma in situ (DCIS). This study examined trends in management and survival for males with DCIS. METHODS The National Cancer Database (NCDB) was queried for males with a diagnosis of DCIS from 2006 to 2017. Patients were categorized by locoregional management. Continuous variables were evaluated by Kruskal-Wallis and categorical variables by chi-square or Fisher's exact test. Univariable and multivariable logistic regressions were performed to evaluate for predictors of patients receiving partial mastectomy (PM) with radiation. Survival was analyzed by Kaplan-Meier. RESULTS Between 2006 and 2017, 711 males with DCIS were identified. Most received mastectomy alone (57.1%). No change was observed in management approach from 2006 to 2017. Patients who underwent mastectomy alone were mostly hormone-positive (95.9% were estrogen-positive, 90.9% were progesterone-positive), although this cohort was least likely to receive hormone therapy (17.2%). Among those who underwent PM with radiation, only 61% of those who were hormone-positive received hormone therapy. Univariable analysis demonstrated that those of black race had lower odds of receiving PM with radiation (odds ratio [OR], 0.58; 95% confidence interval [CI], 0.36-0.84), which persisted in the multivariable analysis with control for age and tumor size (OR, 0.32; 95% CI, 0.15-0.67). Overall survival did not differ significantly between the four treatment methods (p = 0.08). CONCLUSIONS The management approach to male DCIS did not change from 2006 to 2017. Survival did not differ between treatment methods. Demographic and clinicopathologic features, including race, may influence locoregional treatments received, and further studies are needed to further understand this.

[PMID: 38370290 PMCID: PMC10874586 DOI: 10.1177/11782234241233120] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/28/2022] [Accepted: 01/31/2024] [Indexed: 02/20/2024] Open
Abstract
Background Male breast cancer (MBC) accounts for 1% of global breast cancer cases. On account of its rarity, very few prospective clinical trials have been carried out on MBC. Pakistan has the highest incidence of breast cancer in Asia, but very limited data are available on MBC. Objectives The objective is to determine the clinicopathological characteristics and treatment patterns of MBC in Pakistani population. Design This is a retrospective cross-sectional study. Methods A retrospective cross-sectional study carried out using the cancer database of Shaukat Khanum Memorial Cancer Hospital & Research Center. Men with a histologically proven breast cancer, stage 0 to III disease and requiring surgical intervention were included. The Kaplan-Meier curve and log-rank test were used for survival analysis. Results Sixty-eight patients with MBC were included with a median age at diagnosis of 55 years. Most patients were stage II (47.1%). Invasive ductal carcinoma (IDC) was the commonest type (89.7%). Estrogen receptor (ER), progesterone receptor (PR), and Her-2 receptor positivity were 92.6%, 86.8%, and 32.4%, respectively. Mastectomy was performed in 95.6% of the cases. Neoadjuvant and adjuvant chemotherapy was administered in 25 (36.8%) and 26 (38.2%) patients, respectively. Fifty-five (80.9%) patients received adjuvant radiotherapy. Most of the patients (89.7%) received tamoxifen. The 5-year overall and disease-free survival was 88.2% and 80.9%, respectively. Patients receiving neoadjuvant chemotherapy had a better overall and disease-free survival (P = .025). Conclusions Male breast cancer occurs at a relatively earlier age in Pakistani population as compared with Western men. Mastectomy is the preferred surgical option for MBC on account of the advanced disease and delayed presentation. Neoadjuvant chemotherapy has a statistically significant effect on overall and disease-free survival, but in spite of these benefits, it remains underutilized.

Abstract
BACKGROUND Men with breast cancer experience unique physical and emotional challenges. However, a thorough understanding of these experiences including the psychosocial effects and supportive care needs have received less attention. In some settings, men with breast cancer experience stigma within the healthcare system and their care needs are not prioritised. This influences the level of professional support offered, consequently worsening their health and well-being outcomes. This review explored the variabilities in the experiences and treatment modalities of male breast cancer (MBC) across different contexts. METHODS All primary study designs including qualitative, quantitative, and mixed methods studies that reported on the experiences, treatment approaches and outcomes of MBC were included in this systematic review. Six databases (Embase, Medline, PsycINFO, Global Health, CINAHL and Web of Science) were searched for articles from January 2000 to September 2023. A results-based convergence synthesis was used for data analysis and reported using PRISMA guidelines. RESULTS Of the studies screened (n = 29,687), forty-four fulfilled the predetermined criteria and were included. Our findings relating to the experiences and treatment approaches of MBC are broadly themed into three parts. Theme 1-Navigating through a threat to masculinity: describes how males experienced the illness reflecting on detection, diagnosis, coming to terms with breast cancer, and disclosure. Theme 2- Navigating through treatment: captures the experiences of undergoing breast cancer treatment/ management following their diagnosis. Theme 3-Coping and support systems: describes how MBC patients coped with the disease, treatment process, aftercare/rehabilitative care, and the available support structures. CONCLUSIONS Men experience a myriad of issues following a breast cancer diagnosis, especially with their masculinity. Awareness creation efforts of MBC among the public and healthcare practitioners are urgently required, which could change the perception of men in promoting early diagnosis, adherence to treatments, post-treatment monitoring, oncological results and a better quality of life. Considerations for training, education and development of specialised guidelines for healthcare practitioners on MBC would provide the necessary knowledge and skills to enhance their practice through the adoption of person-centred and male-specific care strategies. Professional care intervention and support for MBC should not end after the diagnosis phase but should extend to the entire treatment continuum and aftercare including future research focusing on MBC specific clinical trials. TRIAL REGISTRATION PROSPERO Registration No. CRD42021228778.

Abstract
Male breast cancer (MBC), one of the rare types of cancer among men where the global incidence rate is 1.8% of all breast cancers cases with a yearly increase in a pace of 1.1%. Since the last 10 years, the incidence has been increased from 7.2% to 10.3% and the mortality rate was decreased from 11% to 3.8%. Nevertheless, the rate of diagnoses has been expected to be around 2.6% in the near future, still there is a great lack in studies to characterize the MBC including the developed countries. Based on our search, it is evidenced from the literature that the number of risk factors for the cause of MBC are significant, which includes the increase in age, family genetic history, mutations in specific genes due to various environmental impacts, hormonal imbalance and unregulated expression receptors for specific hormones of high levels of estrogen or androgen receptors compared to females. MBCs are broadly classified into ductal and lobular carcinomas with further sub-types, with some of the symptoms including a lump or swelling in the breast, redness of flaky skin in the breast, irritation and nipple discharge that is similar to the female breast cancer (FBC). The most common diagnostic tools currently in use are the ultrasound guided sonography, mammography, and biopsies. Treatment modalities for MBC include surgery, radiotherapy, chemotherapy, hormonal therapy, and targeted therapies. However, the guidelines followed for the diagnosis and treatment modalities of MBC are mostly based on FBC that is due to the lack of prospective studies related to MBC. However, there are distinct clinical and molecular features of MBC, it is a need to develop different clinical methods with more multinational approaches to help oncologist to improve care for MBC patients.

Abstract
Sentinel lymph node biopsy (SLNB) is currently used as a routine treatment for patients with breast cancer. However, it may not be applicable for patients with male breast cancer (MBC), because they have notably different clinicopathological features from those occurring in females. There is a lack of evidence of SLNB application and safe exemption from axillary lymph node dissection (ALND) in patients with MBC. This study aimed to evaluate the application of SLNB to provide information for the standardized treatment of patients with MBC. The MBC patient records from 4 institutions ranging from January 2001 to November 2020 were retrospectively reviewed. There were 220 patients with MBC with a median age of 60 (range 24-88) years and an average tumor size of 2.3 cm (range 0.5 cm-6.5 cm). Sixty-six percent of patients underwent SLNB, and 39% of them showed positive results. A total of 157 patients underwent ALND, while only half of them had positive nodes, causing unnecessary complications. For patients in the clinical early stage, we found that the SLNB showed a noninferiority to the ALND treatment in DFS (P = .18) and OS (P = .055). In conclusion, there are certain obstacles to the broad application of SLNB due to the lower proportion of patients with clinically negative lymph nodes. However, it is undeniable that SLNB can safely and effectively exempt patients with MBC at early stage with clinically negative nodes from ALND to reduce subsequent complications. It is still an ideal criterion for the axillary staging of patients with MBC.

Abstract
Background Short period from diagnosis to breast cancer (BC) treatment initiation remains challenging for the public health system in Brazil, which may have been further affected by the coronavirus disease-2019 (COVID-19) pandemic. This study assessed BC diagnosis-to-treatment intervals (DTi) in Brazil and the possible effects of the COVID-19 outbreak on delays. Methods The Painel de Monitoramento de Tratamento Oncológico database was queried to obtain the number of Brazilian patients with a BC confirmed diagnosis and initiating cancer treatment in the pre-COVID-19 (2013-2019) and during the COVID-19 (2020-2021) periods, adopting a 60-day limit as timely treatment. A p-value of <0.05 was considered significant. Results A total of 315,951 cases were included (females: 99.3% and males: 0.7%), of which 251,667 and 64,284 records were computed before and during the COVID-19 years, respectively. Most patients failed to perform the first cancer treatment within 60 days (>60: 51.8%). We observed an upward trend in the number of BC treatments provided in the pre-COVID-19 years (r2 = 0.9575; p < 0.05), but the volume of treatments exhibited an average reduction of 24.6% yearly during the COVID-19 pandemic. The average DTi in days was 122.4, 122.5 and 122.3 in the total period studied, before and during the COVID-19 outbreak, respectively. The arrival of COVID-19 in Brazil increased the chances of treatment delay (OR = 1.043; p < 0.05) and inverted the proportion of early/advanced stages at BC diagnosis (55.8%/44.2%-48.4%/51.6%). Conclusion COVID-19 has imposed changes in BC care in Brazil, reducing the number of treatments provided by the Brazilian public health system, increasing the chances of delayed treatment initiation despite no differences in DTi averages being identified, and raising the proportion of advanced-stage diagnoses.

Abstract
Breast cancer in men is rare and often overlooked as there is a misconception that it is a gendered disease that affects women only. The feminization, or "pinkification," of the disease has been socially constructed to raise awareness, improve screening, and empower women but has not addressed the occurrence of the illness in men. Men may therefore experience unique psychosocial difficulties when faced with a disease that predominantly affects women, including feelings of disbelief and embarrassment that impact their sense of self and challenge their masculinity. The lack of mammographic screening in men, lack of public awareness, and the shame that develops during the time of diagnosis can result in treatment avoidant behaviors, a delayed presentation, and worse prognosis in men. Although male breast cancer (MBC) is uncommon, the incidence is increasing; therefore, efforts should be made to enhance education for health care professionals and the general public in order to lessen the stigma, with the goal of improving outcomes. Furthermore, special attention to the unique medical needs and hurdles encountered by transgender males can break down health care barriers in this marginalized patient population. This article offers male perceptions on breast cancer, the psychosocial implications of being diagnosed with a gendered disease, and suggestions on how to improve the MBC experience.

Abstract
OBJECTIVES This research was designed to compare the ability of different machine learning (ML) models and nomogram to predict distant metastasis in male breast cancer (MBC) patients and to interpret the optimal ML model by SHapley Additive exPlanations (SHAP) framework. METHODS Four powerful ML models were developed using data from male breast cancer (MBC) patients in the SEER database between 2010 and 2015 and MBC patients from our hospital between 2010 and 2020. The area under curve (AUC) and Brier score were used to assess the capacity of different models. The Delong test was applied to compare the performance of the models. Univariable and multivariable analysis were conducted using logistic regression. RESULTS Of 2351 patients were analyzed; 168 (7.1%) had distant metastasis (M1); 117 (5.0%) had bone metastasis, and 71 (3.0%) had lung metastasis. The median age at diagnosis is 68.0 years old. Most patients did not receive radiotherapy (1723, 73.3%) or chemotherapy (1447, 61.5%). The XGB model was the best ML model for predicting M1 in MBC patients. It showed the largest AUC value in the tenfold cross validation (AUC:0.884; SD:0.02), training (AUC:0.907; 95% CI: 0.899-0.917), testing (AUC:0.827; 95% CI: 0.802-0.857) and external validation (AUC:0.754; 95% CI: 0.739-0.771) sets. It also showed powerful ability in the prediction of bone metastasis (AUC: 0.880, 95% CI: 0.856-0.903 in the training set; AUC: 0.823, 95% CI:0.790-0.848 in the test set; AUC: 0.747, 95% CI: 0.727-0.764 in the external validation set) and lung metastasis (AUC: 0.906, 95% CI: 0.877-0.928 in training set; AUC: 0.859, 95% CI: 0.816-0.891 in the test set; AUC: 0.756, 95% CI: 0.732-0.777 in the external validation set). The AUC value of the XGB model was larger than that of nomogram in the training (0.907 vs 0.802) and external validation (0.754 vs 0.706) sets. CONCLUSIONS The XGB model is a better predictor of distant metastasis among MBC patients than other ML models and nomogram; furthermore, the XGB model is a powerful model for predicting bone and lung metastasis. Combining with SHAP values, it could help doctors intuitively understand the impact of each variable on outcome.

Abstract
PURPOSE Germline mutations of BRCA1 or BRCA2 predispose men to develop various cancers, including breast cancers and prostate cancers. Male breast cancer (MBC) is a rare disease while prostate cancer (PRC) is uncommon in young men at the age of less than 40. The prevalence of BRCA genes in Asian male patients has to be elevated. METHODS Germline mutations screening was performed in 98 high-risk Chinese MBC and PRC patients. RESULT We have identified 16 pathogenic BRCA2 mutation carriers, 12 were MBC patients, 2 were PRC patients and 2 were patients with both MBC and PRC. The mutation percentages were 18.8%, 6.7% and 50% for MBC, PRC and both MBC and PRC patients, respectively. BRCA2 gene mutations confer a significantly higher risk of breast/prostate cancers in men than those with BRCA1 mutations. BRCA mutated MBC patients had a younger age of diagnosis and strong family histories of breast cancers while BRCA mutated PRC patients had strong family histories of ovarian cancers. CONCLUSION Male BRCA carriers with breast cancers or prostate cancers showed distinct clinical and molecular characteristics, a male-specific genetic screening model would be useful to identify male cancer patients who have a high risk of BRCA mutation.

Abstract
BACKGROUND Concomitant disease is associated with poor breast cancer survival in women and is more prevalent in racial/ethnic minority groups than individuals who are non-Hispanic White. The purpose of this study was to determine if race/ethnicity is associated with survival among men with breast cancer when stratifying analyses by level of comorbidity. METHODS We used the California Cancer Registry to identify 1730 cases of men and 259,828 cases of women with breast cancer and documented Charlson Comorbidity Index (CCI). Kaplan-Meier survival and Cox regression analyses were used to compare breast cancer-specific survival and risk of mortality for African American/Black, Hispanic, and Asian/Pacific Islander men with White women and White men. RESULTS When compared with White women, Black men with a CCI of 0 (hazard ratio [HR], 3.09; 95% CI, 1.10-1.16) and a CCI of 2+, (HR, 2.51; 95% CI, 1.42-4.42) had an increased risk of mortality when compared with White women. When compared with White men, African American men with a CCI of 0 (HR, 2.36; 95% CI, 1.45-3.85) and 2+ (HR, 2.44; 95% CI, 1.26-4.74) had an increased unadjusted risk of mortality, but these disparities were neutralized when controlling for sociodemographic and clinical factors. CONCLUSIONS Black men with both low and high levels of concomitant disease have an increased risk of mortality when compared with both White men and women, but demographic and clinical factors are contributors to this disparity.

Abstract
Purpose The study aimed to document the existing knowledge and practices related to breast cancer recognition and treatment using medicinal plants by traditional health practitioners in Central Uganda. Methods This cross-sectional exploratory survey, conducted between February and August 2020, applied a mixed methods research approach. A semi-structured questionnaire was administered to 119 traditional health practitioners (THPs) in Kampala, Wakiso and Mukono. Content analysis of qualitative data was done. Quantitative ethnobotanical survey indices, namely user reports (Nur), percentage of respondents with knowledge (PRK), informant consensus factor (Fic), fidelity level (FL), preference ranks (PR) and direct matrix ranking (DMR) were determined. Results Most THPs recognized breast cancer by breast swelling (n=74, 62.2%) and breast pain (n=29, 24.4%). They cited 30 plants from 30 genera in 23 families (Fic 0.75 on breast cancer). Asteraceae, Apocynaceae, Euphorbiaceae, Fabaceae, Lamiaceae and Rutaceae were the predominant families. The ten most cited plants were Annona muricata L. (Nur=24), Rhoicissus tridentata (L.f.) Wild & R.B.Drumm (Nur =19), Erythrococca bongensis Pax (Nur=11), Ficus sp. (Nur=10), Cannabis sativa L. (Nur=8), Ipomoea wightii (Wall.) Choisy (Nur=7), Erythrina abyssinica DC. (Nur=5), Leucas martinicensis (Jacq.) R.Br. (Nur=4), Abelmoschus esculentus (L.) Moench (Nur=4) and Zanthoxylum chalybeum Engl. (Nur=3). Annona muricata L. was highly preferred by THPs (PR 1), Ficus sp. had highest fidelity level (FL=77%) and Zanthoxylum chalybeum Engl. ranked as the highest multipurpose plant (DMR 1). Herbs (n=14, 47%) were the most commonly used life forms besides trees (n=11, 37%) and shrubs (n=5, 16%). THPs mostly used leaves (46%), prepared decoctions (82%) and applied residues on the breast. Conclusion THPs in Central Uganda recognized breast cancer by symptoms. Medicinal plants applied in its folk treatment have been documented and the claims of cure by THPs merit further investigation.

Abstract
Breast cancer is the most common cancer in women. The life expectancy after a breast cancer diagnosis is improving steadily, leaving many more persons with the long-term consequences of treatment. Sexual problems are a common concern for breast cancer survivors yet remain overlooked in both the clinical setting and the research literature. Factors that contribute to sexual health concerns in breast cancer survivors are biopsychosocial, as are the barriers to addressing and treating these health concerns. Sexual health needs and treatment may vary by anatomy and gender. Multidisciplinary management may comprise lifestyle modifications, medications, sexual health aids such as vibrators, counseling, and referrals to pelvic health physical therapy and specialty care. In this article, we review the contributing factors, screening, and management of sexual difficulties in cisgender female breast cancer survivors. More information is needed to better address the sexual health of breast cancer survivors whose sexual/gender identity differs from that of cisgender women.

Abstract
Breast cancer (BC) is mainly considered a disease in women, but male BC (MaBC) accounts for approximately 1.0% of BC diagnoses and 0.5% of malignant neoplasms in the western population. The stigmatization of MaBC, the fact that men are less likely to undergo regular health screenings, and the limited knowledge of health professionals about MaBC contribute to men being diagnosed at more advanced stages. The aim of this article is to increase the visibility of MaBC among urologists, who have more contact with male patients. This review highlights key points about the disease, the risk factors associated with MaBC, and the options for treatment. Obesity and increased population longevity are among the important risk factors for MaBC, but published studies have identified family history as extremely relevant in these patients and associated with a high penetrance at any age. There is currently no screening for MaBC in the general population, but the possibility of screening in men at high risk for developing BC can be considered. The treatment of MaBC is multidisciplinary, and, because of its rarity, there are no robust clinical studies evaluating the role of systemic therapies in the management of both localized and metastatic disease. Therefore, in current clinical practice, treatment strategies for men with breast cancer are extrapolated from information arising from studies in female patients.

Abstract
BACKGROUND Although male breast cancer (MBC) is a rare disease, accounting for <1% of all breast cancers, it has significant oncological, survival and psychosocial implications for patients. The aim of this study is to assess the latest literature in the diagnosis, management, oncological outcomes, and psychosocial impact of MBC. METHODS A systematic literature review was conducted using the PRISMA guidelines (Moher et al., 2009) [1] to explore the management of MBC, with particular focus on investigative imaging, surgical management, oncological outcomes, survival, genetic screening and psychosocial effects. Electronic databases were searched for randomised control trials, cohort studies and case series involving more than 10 patients. Imaging and surgical techniques, local and distant disease recurrence, survival, genetic screening and psychosocial implications in the setting of MBC were assessed. RESULTS The search criteria identified 199 articles, of which 59 met the inclusion criteria. This included 39,529 patients, with a mean age of 64.5 years (55-71), and a mean follow-up of 66.3 months (26.2-115). Mastectomy remains the most frequently used surgical technique, with an average of 89.6%. Loco-regional and distant recurrence rate was 10.1% and 21.4% respectively. Disease-free survival (DFS) at 5 and 10 years was 66.8% and 54.5% respectively. Disease-specific survival (DSS) at 5 and 10 years was 87.1% and 67.1% respectively. Overall survival (OS) at 5 and 10 years was 72.7% and 50.7% respectively. Genetic screening was conducted in 38.6% of patients of which 4.8% and 15.8% were found to be BRCA1 and BRCA2 carriers respectively. Psychosocial studies were conducted mainly using questionnaire and interview-based methodology focusing primarily on awareness of breast cancer in men, support available and impact on gender identity. CONCLUSIONS This review demonstrates that men present with later stage disease with subsequent impact on survival outcomes. There remains a paucity of high-level evidence and prospective studies are required. There is a need for increasing awareness amongst the public and health care professionals in order to improve outcomes and reduce stigma associated with MBC.

Abstract
Introduction Less than 1% of all breast cancers are diagnosed in males. In females, postmastectomy breast reconstruction is associated with increased patient satisfaction. However, there is a paucity of literature describing reconstructive options for postmastectomy deformity in the male chest. The purpose of this systematic review was to evaluate postmastectomy reconstruction outcomes in males with breast cancer. Methods A systematic review was performed in accordance with PRISMA guidelines. Ovid MEDLINE, Embase, Cochrane, and Web of Science were queried for records pertaining to the study question using medical subject heading (MeSH) terms such as "male breast cancer," "mastectomy," and "reconstruction." No limitations were placed on the year of publication, country of origin, or study size. Study characteristics and patient demographics were collected. Primary outcomes of interest included postoperative complications, recurrence rate, and mortality rate. Results A total of 11 articles examining 29 male patients with breast cancer who underwent postmastectomy reconstruction were included for analysis. Literature was most commonly available in the form of case reports. The average age was 59.6 +/-11.4 years. Reconstruction methods included fat grafting (n = 1, 3.4%), silicone implants (n = 1, 3.4%), and autologous chest wall reconstruction with local flaps (n = 26, 89.7%). Postoperative complications occurred in two patients (6.8%), including partial nipple necrosis (n = 1) and hypertrophic scarring (n = 1). Of the studies reporting patient satisfaction, all patients were pleased with the aesthetic appearance of their chest. Conclusion This systematic review revealed the limited availability of research regarding postmastectomy chest reconstruction in males with breast cancer. Nevertheless, the evidence available suggests that reconstruction can restore a patient's body image and, thus, should be regularly considered and discussed with male patients. Larger studies are warranted to further shed light on this population.

Abstract
Male breast cancer (MBC) is now considered molecularly different from female breast cancer (FBC). Evidence from studies indicates that common genetic and epigenetic features of FBC are not shared with those diagnosed in men. Genetic predisposition is likely to play a significant role in the tumorigenesis of this rare disease. Inherited germline variants in BRCA1 and BRCA2 account for around 2% and 10% of MBC cases, respectively, and the lifetime risk of breast cancer for men harboring BRCA1 and BRCA2 mutations is 1.2% and 6.8%. As for FBC, pathogenic mutations in other breast cancer genes have also been recently associated with an increased risk of MBC, such as PALB2 and CHEK2 mutations. However, while multigene germline panels have been extensively performed for BC female patients, the rarity of MBC has resulted in limited data to allow the understanding of the magnitude of risk and the contribution of recently identified moderate penetrance genes of FBC for MBC predisposition. This review gathers available data about the germline genetic landscape of men affected by breast cancer, estimated risk associated with these genetic variants, and current guidelines for clinical management.

Abstract
Introduction Male breast cancer is uncommon, delay in seeking medical attention often results in late presentation and poor prognosis. Methods Retrospective review of a prospectively maintained database was performed. Patients who were still having regular follow‐up were contacted for telephone interview. Results In this study, 56 male breast cancer patients were treated in our center from January 1998 to December 2018, accounting for 0.88% of all breast cancers treated during the same period of time. Median age of onset was 61 years old (Range: 33‐95). In this study, 6 (10.7%) patients presented with distant metastasis at the time of diagnosis and received palliative systemic treatment only. And, 50 patients were surgically treated and all had mastectomy. Axillary dissection was performed in 36 (72%) patients, while sentinel node biopsy was performed in 14 (28%) patients. Median tumor size was 23 mm (2‐100 mm). A Majority were diagnosed with invasive carcinoma (NOS), while 38 (67.8%) patients were node positive.Here 36 (64.3%) patients were alive at the time of the study, 31 (86.1%) patients responded to the telephone interview. More than 90% of our patients expressed various degrees of embarrassment at the time of breast symptom onset. Similarly, more than 90% of these patients experienced embarrassment while waiting in the breast center with predominant female patients. Most patients (N = 26) were not aware that breast cancer can occur in men prior to the diagnosis. Median duration from symptoms to the first medical consultation was 12.4 months (1‐120 months). Conclusion Male breast cancer is rare and patients usually present late, Lack of knowledge, public education, and embarrassment are the important related factors.
