Male breast cancer - a single center experience.

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 Tren?ín (Tren?ín, 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.

Project description:Simple Summary In Asian patients with breast cancer, venous thromboembolism (VTE) has been an under-recognized condition. We demonstrated close association between VTE and breast cancer in a Korean cohort. The incidence of VTE was not low, as previously described. The risk factors for VTE included old age, male breast cancer, chronic kidney disease, breast reconstruction, and advanced stage. VTE was associated with poor disease-free and overall survival. Most of the patients with VTE were manageable with anticoagulation, although mortality occurred in some patients. Our findings provide valuable information on comprehensive care for Asian patients with breast cancer. Abstract The relationship between cancer and venous thromboembolism (VTE) has long been described. The risk of VTE in Asian patients with breast cancer remains largely unknown. This study described the incidence and risk factors of VTE in Korean patients with breast cancer. Data were collected from a retrospective database of patients who underwent breast cancer surgery between 2011 and 2020 at a single institution. The Cox proportional-hazards model was used to identify factors associated with VTE occurrences. Among the 2246 patients with breast cancer, 48 (2.1%) developed VTE during a median follow-up period of 53 months. The average incidence of VTE was 459 per 100,000 person-years. Age ≥ 60 years, male sex, chronic kidney disease, reconstructive procedures, and stage II or higher were independent predictive factors for VTE. VTE was associated with poor disease-free survival (hazard ratio (HR), 6.140; 95% confidence interval (CI), 3.480–10.835), and overall survival (HR, 8.842; 95% CI 4.386–17.824). Most VTE events were manageable with anticoagulation; three (6.3%) patients died of VTE, despite intensive care. The incidence of VTE was significantly elevated in Korean patients with breast cancer. Since VTE has a negative effect on oncologic outcomes of breast cancer, clinicians should manage its risk throughout their lifetime.
