Background: Male breast cancer is a rare neoplasm, and its treatments are based on those of female breast cancer. This study aimed to analyze 20 years of male breast cancer clinical characteristics and treatment results from the Middle Black Sea Region of Turkey. Materials and Methods: A retrospective analysis of 16 male breast cancer patients treated in our tertiary hospital between 1994 and 2014 was performed. Epidemiologic data, tumor characteristics, and treatments were recorded and compared with 466 female breast cancer ((premenopausal; n = 230) + (postmenopausal n = 236)) patients. The 5-year disease-free and overall survival rates were calculated. Results: Male breast cancer constituted 0.1% of all malignant neoplasms in both sexes, 0.2% of all malignant neoplasms in males, and 0.7% of all breast cancers. The mean patient age in this study was $59.8{\pm}9.5$ (39-74) years. The mean time between first symptom and diagnosis was $32.4{\pm}5.3$ (3-60) months. Histology revealed infiltrative ductal carcinoma in 81.3% of patients. The most common detected molecular subtype was luminal A, in 12 (75%) patients. Estrogen receptor rate (93.8%) in male breast cancer patients was significantly higher than that in female breast cancer (70.8% in all females, p = 0.003; 68.2% in postmenopausal females, p = 0.002) patients. Most of the tumors (56.3%) were grade 2. Tumor stage was T4 in 50% of males. The majority (56.3%) of the patients were stage III at diagnosis. Surgery, chemotherapy, radiotherapy and endocrine-therapy were applied to 62.5%, 62.5%, 81.2% and 73.3%, respectively. Loco-regional failure did not occur in any of the cases. All recurrences were metastastic. The 5-year disease-free and overall survival rates in male breast cancer patients were 58% and 68%, respectively. Conclusions: Tumors found in male breast cancer patients were similar in size to tumors found in females, but they advanced to T4 stage more rapidly because of the lack of breast parenchymal tissues. The rate of estrogen receptor expression tended to be higher in male breast cancer patients than in female breast cancer patients. Metastasis is the most important problem in initially non-metastatic male breast cancer patients.

Background: Male and female breast cancers were investigated for variation in the clinicopathologic characteristics and expression of steroid hormone receptors in the northeast of Iran. Materials and Methods: Tumor specimens of 17 males and 338 females with breast cancer were collected at the hospitals of Mashhad University of Medical Sciences. Immunohistochemical expression of hormone receptors and clinicopathologic features of breast cancer were compared between two groups. Results: The mean age in men was 15 years higher than women (p=0.000). Males and females were mainly in stage II and III respectively (p=0.007). Although more than 60% of male and female patients were grade II, the respective figures for grade I and III were 25% and 12.5% in men but 7.1% and 27.2% in women respectively (p=0.025). ER was significantly more positive in men against women; 82.3% versus 53.4% (p=0.016). The related measures for PR was 58.8% and 50.3%, respectively (p=0.424). Males also showed significantly more ER expression than postmenopausal females; 82.3% versus 48.9% (p=0.010). Conclusions: Breast cancer in males and females contrasted in age at diagnosis, histological type, stage, grade and ER expression which emphasize they are separate diseases with different behaviors.

Background: The aim of this study was to analyze the demographic and clinical characteristics of male breast cancer patients in Serbia, and furthermore to determine overall survival and predictive factors for prognosis. Materials and Methods: In the period of 1996-2006 histopathological diagnosis of breast cancer was made in 84 males at the Institute for Oncology and Radiology of Serbia. For statistical analyses the Kaplan-Meier method, long-rank test and Cox proportional hazards regression model were used. Results: The mean age at diagnosis with breast cancer was $64.3{\pm}10.5$ years with a range from 35-84 years. Nearly 80% of the tumors showed ductal histology. About 44% had early tumor stages (I and II) whereas 46.4% and 9.5% of the male exhibitied stages III and IV, respectively. Only 7.1% of male patients were grade one. One-fifth of all patients had tumors measuring ${\leq}2cm$, and 14.3% larger than 5 cm. Lymph node metastasis was recorded in 40.4% patients and 47% relapse. Estrogen and progesterone receptor expression was positive in 66.7% and 58.3%, respectively. Among 14.3% of individuals tumor was HER2 positive. About two-thirds of all male patients had radical mastectomy (66.7%). Adjuvant hormonal (tamoxifene), systematic chemotherapy (CMF or FAC) and adjuvant radiotherapy were given to 59.5%, 35.7% and 29.8% patients respectively. Overall survival rates at five and ten years for male breast cancer were 55.0% and 43.9%, respectively. According to the multivariate Cox regression predictive model, a lower initial disease stage, a lower tumor grade, application of adjuvant hormone therapy and no relapse occurrence were significant independent predictors for good overall survival. Conclusions: Results of the treatment would be better if disease is discovered earlier and therefore health education and screening are an imperative in solving this problem.

Background: Male breast cancer accounts for less than 1% of all cancers found in men. It usually presents at a later age and stage as compared to female breast cancer. Treatment strategies are extrapolated from the management of female breast cancer. Our study here looked at 18 patients diagnosed with and treated for male breast cancer at The Aga Khan University Hospital in Pakistan. We compared our findings with the existing data from Asian and Western countries. Materials and Methods: A retrospective study was conducted looking at patients with male breast cancer between January 1986 and December 2009. Patient and disease characteristics were analyzed and 5 year overall survival was calculated using Microsoft Excel and SPSS. Results: The average age at diagnosis was 52 years (38-67 years). Twelve (66.7%) patients had axillary lymphadenopathy. Stage II disease was the most common stage at presentation (9 patients, 50%). Infiltrating ductal carcinoma was seen in 16 patients (88.8%). Seven lesions were positive for both estrogen and progesterone receptors. Sixteen patients had surgery in the form of either modified radical mastectomy or radical mastectomy. Radiation was used in 7 patients in an adjuvant setting. The five year overall survival for stage I, II, III and IV disease was 100% vs 78% vs 50% vs 0%( p<0.05). Five year overall survival was 61%. None of the other prognostic factors were statistically significant. Median follow up was 15 months (3-202 months). Conclusions: Male breast cancer may be on a slow rise but is still an uncommon disease. Tumor stage and lymph node status are important prognostic markers. Public awareness and screening may help in detecting the disease at an earlier stage. Prospective trials are needed to improve the management of this disease.

Background: Male breast cancer accounts for less than 1% of all cancer in men and only around 1% of all diagnosed breast cancer. Despite a significant raise in the last 25 years, it still remains a rare disease. Materials and Methods: We conducted a retrospective study from 2004-2011 with 21 male breast cancer patients. We aimed to analyze the epidemiologic data (age, personal and family history), tumor characteristics (size, histological type, location, TNM stage, receptors), surgery, adjuvant chemotherapy and radiation therapy, hormonal therapy and survival (relapse, follow up, death) who reffered to our center with breast cancer. Results: The median age was $49.2{\pm}14.2$ years (range 30-83 years). A family history of breast cancer was noted in four cases. The main clinical complaint was a retroareolar mass in 85.7%of patients (n=18). Histologically, 85.7% (n=18)were invasive ductal carcinoma and 4.7% (n=1) had ductal carcinoma in situ and 9.4% (n=2) had mixed histology including invasive medullary and ductal carcinoma. Hormonal therapy was delivered to 16 cases (76.1%) due to ER or PR positivity. During median follow up of 30 months (3-84 month), distant metastases were evident in 4 cases (19%). During the follow-up period, only one patient died due to metastatic disease. The mean time to recurrence detection was 30 months. Conclusions: The percentage of cases of male breast cancer is very low compared to breast cancer in females, explaining why very few investigations have been conducted in Iran. Limited coverage in the literature make gender-specific findings difficult so future research of this entity involving multi-institutional cooperation and longer follow up is essential to provide new insights about the biological and clinical factors of this rare cancer.

To observe and analyze the characteristic trend of cancer patients hospitalized for the first time in Shanxi Tumor Hospital from 2001 to 2010, clinical data including case number, age, gender, and frequency of different tumor occurrences were collected and statistically analyzed. Results: (i) From 2001 to 2010, the number of cancer patients hospitalized for the first time increased by 1.3-fold; (ii) The patient overall average age also increased from 51.8 to 54.4, for males from 55.5 to 58.7 and females from 48.4 to 51.1, respectively. (iii) Male patients accounted for 43-48% and females accounted for 52-57% of the total. The percentage of female patients was higher than that of male patients in every year and showed an upward trend over the years, while that of the males showed a downward trend (${\chi}^2=7.031$, p=0.008); (iv) Among the top 6 most common cancers, lung, cervical, esophageal, colorectal and breast cancers tended to increase over the years (p<0.05), but not gastric cancer (p=0.423). Conclusions: (i) The number of cancer patients hospitalized for the first time during the past 10 years increased year by year, and was higher for female than male; (ii) the average age of patients increased year after year and was greater for male than female; (iii) the number of patients with lung cancer, cervical cancer, esophageal cancer, colorectal cancer and breast cancer increased over years.

Breast cancer is the most frequent cancer of women worldwide, with considerable geographic and racial/ethnic variation. Data are generally derived from population based cancer registries in the developed countries but hospital data are the most reliable source in the developing countries. Ten years data from 1st Jan 2000 to 31st Dec 2009 of a cancer hospital in Pakistan were here analyzed by descriptive statistics to evaluate the clinicopathologic profile of local breast cancer patients. Among 28,740 cancer patients, 6,718 were registered as breast cancer. The female to male ratio was 100:2. Breast cancer accounted for 23% of all and 41% of female cancers. Some 46% were residents of Lahore, with a mean age of $47{\pm}12$ years. Less than 1% were at Stage 0 and 10%, 32%, 35% and 23% were at Stage I, II, III and IV respectively. Histopathology was unknown in 4% while 91%, 2% and 1% had invasive ductal carcinoma (IDC), invasive lobular carcinoma (ILC) and mucinous carcinoma respectively. Rare carcinomas accounted for the rest. Tumor grade 1, 2 and 3 was 11%, 55% and 34% among the known. Profile of breast cancer patients in Pakistan follows a pattern similar to that of other developing countries with earlier peak age and advanced disease stage at presentation. The male breast cancer accounts for higher proportion in the local population. Local women have higher frequency of IDC and lower frequency of ILC and DCIS, owing probably to a different risk profile. Use of hospital information systems and establishment of population based cancer registry is required to have accurate and detailed local data. Promotion of breast health awareness and better health care system is required to decrease the burden of advanced disease.

A statistical analysis was made on 15,971 surgically operated patients at D-Medical Center in the year of 1978 and 1988. 1,416 cancer patients among them were classified by sex, age, and malignant tumor site. The obtained results indicated that trend of male cancer was generally similar to the results of nation wide study. But, specific phenomenon was found in the case of female cancer in Daegu-Kyungbuk area. Among females the frequency rank was uterine cervix (35.77%), breast (17.97%), stomach (11.65%) in 1988. The frequency of uterine cervix was higher than other area. Breast cancer was highly ranked tumor compare with other area, and its age distribution also appeared in much younger decade.
