Prognosis versus Actual Outcomes in Stereotactic Radiosurgery of Brain Metastases: Reliability of Common Prognostic Parameters and Indices. Curr Oncol 2024; 31:1739-1751. [PMID: 38668035 PMCID: PMC11049204 DOI: 10.3390/curroncol31040132] [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: 01/31/2024] [Revised: 03/11/2024] [Accepted: 03/21/2024] [Indexed: 04/28/2024] Open
Abstract
This study aims to evaluate the clinical outcome of stereotactic radiosurgery as the sole treatment for brain metastases and to assess prognostic factors influencing survival. A total of 108 consecutive patients with 213 metastases were retrospectively analyzed. Treatment was determined with close-meshed MRI follow-up. Various prognostic factors were assessed, and several prognostic indices were compared regarding their reliability to estimate overall survival. Median overall survival was 15 months; one-year overall survival was 50.5%. Both one- and two-year local controls were 90.9%. The rate of new metastases after SRS was 49.1%. Multivariate analysis of prognostic factors revealed that the presence of extracranial metastases, male sex, lower KPI, and progressive extracranial disease were significant risk factors for decreased survival. Of all evaluated prognostic indices, the Basic Score for Brain Metastases (BSBMs) showed the best correlation with overall survival. A substantial survival advantage was found for female patients after SRS when compared to male patients (18 versus 9 months, p = 0.003). SRS of brain metastasis is a safe and effective treatment option when frequent monitoring for new metastases with MRI is performed. Common prognostic scores lack reliable estimation of survival times. Female sex should be considered as an additional independent positive prognostic factor influencing survival.

Abstract
Male breast cancer is a rare disease, accounting for less than 1% of all cases of breast cancer. However, the incidence of male breast cancer is increasing. In this study, we systematically analyzed the cases of male breast cancer and evaluated the management of operable male breast cancer in daily clinical practice according to the international clinical guidelines. Data of male breast cancer characteristics and management were recorded from our electronic database. We present a case series of male breast cancer patients treated at our institution between 2013 and 2021 and summarize the recommendations on management of male patients with breast cancer. Twenty-six patients met the search criteria. The majority of tumors were hormone-receptor positive and human epidermal growth factor receptor 2 negative. Two tumors were derived from axillary accessory breast. All patients underwent mastectomy. Fifteen patients received adjuvant chemotherapy containing anthracycline or taxane. Ten patients received adjuvant radiotherapy for lymph node metastasis. Twenty-five patients received adjuvant endocrine therapy. None of patients received anti-human epidermal growth factor receptor 2 therapy. During the median follow-up period of 37 months, one patient died of previous lung cancer recurrence and one patient developed lung metastases 2 years after breast surgery. No recurrence or distant metastasis occurred in the other twenty-four patients. The incidence of male breast cancer is low. In this study, we present twenty-six cases of male patients with operable breast cancer in our department. All of them received surgery and adjuvant treatment. Early diagnosis and combined therapy benefit male patients with breast cancer. Surgery together with adjuvant treatment can bring a good prognosis.

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.

Adjuvant Radiation Therapy for Male Breast Cancer-A Rare Indication? Cancers (Basel) 2020; 12:cancers12123645. [PMID: 33291697 PMCID: PMC7761961 DOI: 10.3390/cancers12123645] [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: 10/21/2020] [Revised: 11/30/2020] [Accepted: 12/01/2020] [Indexed: 11/17/2022] Open
Abstract
Due to its rarity, there are no randomized trials investigating the outcome of adjuvant radiotherapy in MBC. This study reports on patient and tumor characteristics of 41 consecutive MBC patients treated between 1990 and 2018 and on clinical outcomes after surgical resection of tumors and adjuvant radiotherapy of the chest wall or breast. Local control (LC), locoregional control (LRC), overall survival (OS), disease-free survival (DFS), and toxicity were evaluated. After a median follow-up of 80 months (95% CI: 14.6-213.8 months) there was only one recurrence, in a patient's locoregional lymph nodes 17 months after start of radiotherapy, resulting in an LC rate of 100% at 5 years and a 5-year LRC rate of 97.4% (standard deviation (SD): 0.025). Five-year DFS and OS rates were 64.6% (SD: 0.085) and 57.2% (SD: 0.082), respectively. Adjuvant radiotherapy was tolerated well without high-grade (CTCAE grade > II) adverse events. After tumor resection and adjuvant radiotherapy, LC and LRC rates in MBC patients are excellent and comparable to results found for female breast cancer (FBC) patients. However, as patients are often diagnosed with locally advanced, higher-risk tumors, distant recurrences remain the major failure pattern.

Pattern of care of adjuvant radiotherapy in male breast cancer patients in clinical practice: an observational study. Strahlenther Onkol 2018; 195:289-296. [PMID: 30046931 DOI: 10.1007/s00066-018-1337-8] [Citation(s) in RCA: 5] [Impact Index Per Article: 0.8] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/17/2018] [Accepted: 07/04/2018] [Indexed: 01/21/2023]
Abstract
BACKGROUND AND PURPOSE Due to the rarity of male breast cancer (male BC), no consensus has been reached regarding the most appropriate curative treatment strategy. The objective of the present observational study was to identify patient and tumor characteristics and assess the role of radiotherapy (RT) in clinical practice. METHODS Between 1998 and 2014, data of male BC patients treated at two breast centers were consecutively collected and retrospectively analyzed. Patients were stratified based on the addition of adjuvant RT. Data on overall survival (OS) and local recurrence-free survival (LRFS) were estimated with the Kaplan-Meier method and compared by the log-rank test. RESULTS A consecutive cohort of 58 male BC patients was evaluated. Median follow-up was 56 months. Twenty-one patients (36.2%) received adjuvant RT. Overall, patients undergoing postoperative RT were characterized by more high-risk features. Patients receiving postoperative RT had significantly more frequently a high UICC stage (50 vs. 9.7% UICC III, p = 0.018) and positive lymph nodes as compared to patients undergoing surgery alone (65 vs. 34.4% pN+, p = 0.046). Accordingly, there was a higher proportion of patients receiving axillary lymph node dissection in the RT group (71.4 vs. 35.6%). Mastectomy was performed in 31/37 (86.1%) in the surgery group as compared to 14/21 (66.7%) in patients receiving postoperative RT. In addition, RT patients were more likely to receive endocrine therapy (78.9 vs. 39.3%, p = 0.016). Outcome was not significantly different between the groups (5-year LRFS: 89.8 vs. 80.0%, p = 0.471 and 5‑year OS 88.4 vs. 88.9%, p = 0.819). CONCLUSION The present observational study evaluated the pattern of care in male BC patients treated in clinical practice. Due to its rarity, randomized clinical trials are unlikely and male BC remains an entity with a poor evidence base. Nevertheless, RT remains a crucial component of the multidisciplinary treatment strategy in male BC.

Abstract
BACKGROUND Male breast cancer is rare and understudied compared with female breast cancer. A current comparison with female breast cancer could assist in bridging this gap. Although conflicting data have been reported on male and female survival outcomes, data from 1973 through 2005 in the Surveillance, Epidemiology, and End Results (SEER) program have demonstrated that the improvement in breast cancer survival in men has fallen behind that of women. As treatment for breast cancer has improved significantly, an updated analysis using a contemporary population is necessary. MATERIALS AND METHODS An analysis of SEER data from patients with a diagnosis of primary breast cancer from 2005 to 2010 were included. A Cox regression model was used to examine the association between sex and breast cancer mortality after controlling for prognostic factors, including age, race, marital status, disease stage, estrogen and progesterone receptor status, lymph node involvement, tumor grade, surgery, and geography. Subgroup analyses were performed by race and stage. RESULTS We included a total of 289,673 breast cancer cases (2054 men) with a diagnosis from 2005 to 2010. The 5-year survival rate for male patients was lower than that for female patients (82.8% vs. 88.5%). After controlling for other factors, the risk of death in men was 43% greater than that in women during the follow-up period (hazard ratio, 1.43; 95% confidence interval, 1.26-1.61). Similar results were noted in the race and stage subgroup analyses. CONCLUSION In recent years, male breast cancer patients have had worse survival outcomes compared with those of female patients.

Abstract
Sex-associated differences in bone metastasis formation from breast, lung, and prostate cancer exist in clinical studies, but have not been systematically reviewed. Differences in the bone marrow niche can be attributed to sexual dimorphism, to genetic variations that affect sex hormone levels, or to the direct effects of sex hormones, natural or exogenously delivered. This review describes the present understanding of sex-associated and sex hormone level differences in the marrow niche and in formation of bone metastasis during the transition of these three cancers from treatable disease to an often untreatable, lethal metastatic one. Our purpose is to provide insight into some underlying molecular mechanisms for hormonal influence in bone metastasis formation, and to the potential influence of sexual dimorphism, genetic differences affecting sex assignment, and sex hormone level differences on the bone niche and its favorability for metastasis formation. We reviewed publications in PubMed and EMBASE, including full length manuscripts, case reports, and clinical studies of relevance to our topic. We focused on bone metastasis formation in breast, lung, and prostate cancer because all three commonly present with bone metastases. Several clear observations emerged. For breast cancer bone metastasis formation, estrogen receptor (ER) signaling pathways indicate a role for ER beta (ERβ). Estrogen influences the bone microenvironment, creating and conditioning a favorable niche for colonization and breast cancer progression. For lung cancer, studies support the hypothesis that females have a more favorable bone microenvironment for metastasis formation. For prostate cancer, a decrease in the relative androgen to estrogen balance or a “feminization” of bone marrow favors bone metastasis formation, with a potentially important role for ERβ that may be similar to that in breast cancer. Long-term estrogen administration or androgen blockade in males may feminize the bone marrow niche to one more favorable for bone metastases in prostate cancer. Administration of androgens in females, especially combined with mastectomy, may reduce risk of developing bone metastatic breast cancer. We conclude that it should be considered that females, those with female-leaning genetic variations, or hormonal states that feminize the bone marrow, may offer favorable sites for bone metastases.

Abstract
PURPOSE To compare the disease-free survival (DFS) and overall survival (OS) rates of men and women undergoing treatment for breast cancer. METHODS A retrospective cohort study of patients with breast cancer diagnosed and treated at the Cancer Hospital III of the National Cancer Institute of Brazil, Rio de Janeiro, Brazil, between 1999 and 2013. Male breast cancer cases were matched for age, year of diagnosis, and clinical staging to three female cases (1:3). Patient characteristics were abstracted from hospital records and medical charts. Cases were analyzed using descriptive statistics, and comparisons between the genders were performed using Kaplan-Meier curves and Cox regression analysis with 95% confidence intervals. RESULTS The study population comprised 98 men and 294 women. There were significant differences (p < 0.05) between the genders for marital status, alcohol consumption, smoking, presence of hypertension and other comorbidities, histological type of tumor, expression of estrogen receptors, progesterone receptors, human epidermal growth factor receptor-type 2, type of breast surgery, neoadjuvant chemotherapy, adjuvant radiotherapy, and use of palliative bisphosphonate therapy. Five- and 10-year DFS rates were, respectively, 80.0 and 51.4% for men and 71.4 and 63.5% for women (p = 0.245), and 5- and 10-year OS rates were, respectively, 65.0 and 47.5% for men and 56.5 and 41.4% for women (p = 0.221). CONCLUSION There was no significant difference in prognosis (DFS and OS rates) between the genders, but significant differences in sociodemographic and clinical characteristics were detected between male and female breast cancer cases.

Abstract
Due to its rarity, male breast cancer remains a poorly characterized disease. The present study obtained retrospective clinicopathological data, treatment patterns and outcomes for all male patients diagnosed with breast cancer in the Oncology Department, Faculty Hospital Trenčín (Trenčín, Slovakia) over the last 20 years from January 1995 to December 2015. A total of 21 patients with male breast cancer were analyzed, with a median patient age of 65.6 years. Two patients were diagnosed with lobular invasive cancer; all others were diagnosed with cancer of a ductal origin. One patient presented with metastatic disease in the pleural cavity. The primary tumors in 8 patients were staged as pT1, whilst 6 patients were staged as pT2 and 7 as pT4. Axillary lymph node involvement was present in 11 patients (52%) and 15 patients were hormone receptor-positive (83%). All but 1 patient underwent mastectomy and surgical staging of the axilla. Adjuvant chemotherapy, radiotherapy and hormone treatment was administered in the same manner as breast cancer treatment in female patients. The median follow-up time was 4.5 years. The 5- and 10-year overall survival rates were 87 and 74%, respectively, and the estimated median disease-free survival for the same population was 9.5 years (95% confidence interval, 6.2-14.6). The survival rates reported in the present retrospective study are comparable with previously published studies. In addition, the current study reported predominant hormone-positive characteristics and rare expression of human epidermal growth factor receptor 2. However, further multi-institutional trials are required to allow for informed treatment decisions in this uncommon disease.

Abstract
BACKGROUND AND PURPOSE Since the last recommendations from the Breast Cancer Expert Panel of the German Society for Radiation Oncology (DEGRO) in 2008, evidence for the effectiveness of postmastectomy radiotherapy (PMRT) has grown. This growth is based on updates of the national S3 and international guidelines, as well as on new data and meta-analyses. New aspects were considered when updating the DEGRO recommendations. METHODS The authors performed a comprehensive survey of the literature. Data from recently published (meta-)analyses, randomized clinical trials and international cancer societies' guidelines yielding new aspects compared to 2008 were reviewed and discussed. New aspects were included in the current guidelines. Specific issues relating to particular PMRT constellations, such as the presence of risk factors (lymphovascular invasion, blood vessel invasion, positive lymph node ratio >20 %, resection margins <3 mm, G3 grading, young age/premenopausal status, extracapsular invasion, negative hormone receptor status, invasive lobular cancer, size >2 cm or a combination of ≥ 2 risk factors) and 1-3 positive lymph nodes are emphasized. RESULTS The evidence for improved overall survival and local control following PMRT for T4 tumors, positive resection margins, >3 positive lymph nodes and in T3 N0 patients with risk factors such as lymphovascular invasion, G3 grading, close margins, and young age has increased. Recently identified risk factors such as invasive lobular subtype and negative hormone receptor status were included. For patients with 1-3 positive lymph nodes, the recommendation for PMRT has reached the 1a level of evidence. CONCLUSION PMRT is mandatory in patients with T4 tumors and/or positive lymph nodes and/or positive resection margins. PMRT should be strongly considered in patients with T3 N0 tumors and risk factors, particularly when two or more risk factors are present.

Abstract
OBJECTIVE The objective of the study was to compare disease-free survival and overall survival in a group of matched males and females with breast cancer, and to analyze possible treatment- and gender-related differences. METHODS We retrospectively analyzed the data of 150 operable male breast cancer patients treated in our hospital from December 1980 to June 2012. Each male breast cancer patient recorded in the database was matched with two female breast cancer patients of equal stage. Prognosis in terms of disease-free survival and overall survival was evaluated. RESULTS The mean age at diagnosis was 58.6 ± 9.7 years for males and 57.2 ± 10.3 years for females. The median follow-up was 69 months for males and 81 months for females. Significant differences were identified for tumor location, hormone receptor status, molecular subtypes and hormone therapy between the two groups. Monofactorial analysis demonstrated that tumor size, lymph node state, American Joint Committee on Cancer stage, molecular subtypes and adjuvant chemotherapy treatment were prognostic factors in male breast cancer patients. The 5- and 10-year disease-free survival rates were 65.6 and 40.1% for males, and 74.9 and 51.5% for females, respectively. The 5- and 10-year overall survival rates were 72.9 and 53.9% for males, and 83.2 and 68.5% for females, respectively. There was significantly difference in disease-free survival and overall survival between the two matched groups (P = 0.002). CONCLUSIONS Male breast cancer patients had inferior outcome despite of equal stage in comparison with matched female breast cancer patients, which demonstrates that biological differences may contribute to the worse prognosis.
