Objective To analyze the incidence and mortality of male breast cancer in Hubei Province from 2012 to 2015. Methods The data reported by the Hubei Provincial Cancer Registry from 2012 to 2015 were collected for analyzing the incidence and mortality trends of male breast cancer according to year, urban and rural areas and age. We also compared the difference of incidence and mortality between male and female breast cancer. Results A total of 106 new cases of male breast cancer were reported in Hubei Cancer Registry from 2012 to 2015 with an incidence rate of 0.43/10⁵, and 10052 new cases of female breast cancer with an incidence rate of 42.76/10⁵; the male-to-female incidence ratio was 1:99. Male breast cancer death cases was 37 with the death rate of 0.15/10⁵, and female breast cancer death cases was 2201 with the death rate of 9.36/10⁵; the male-to-female mortality ratio was 1:62. The incidence and mortality of breast cancer between male and female varied by year, urban and rural areas. Male breast cancer was less common in young men (< 35 years old), and the incidence increased with age after 35 years old; male breast cancer deaths were rare in men under 45 years old, and the mortality rate increased with age. The incidence and mortality of male breast cancer patients over 85 years old reached the peak. Conclusion Male breast cancer is rare in clinical practice, and the incidence rate is much lower than that of female breast cancer. Even so, it is necessary to study the epidemiological law of male breast cancers' incidence and mortality, which can be used for prevention and treatment of male breast cancer.

Objective To investigate the application value of laparoscopic hepatectomy (LH) in the treatment of liver neoplasms. Methods Clinical data of 78 patients with liver neoplasms undergoing hepatectomy in Zhongnan Hospital of Wuhan University from June 2011 to June 2014 were retrospectively analyzed. The patients were divided into the LH group (n=31) and open hepatectomy (OH) group (n=47). The informed consents of all patients were obtained and the local ethical committee approval had been received. Intra-and post-operative situation and liver function of two groups were compared. Normally distributed data of two groups were compared with t test, non-normally distributed data were compared with rank-sum test and the comparison of rate was conducted using Chi-square test. Results Intraoperative blood loss, length of wound, retention time of abdominal drainage catheter, postoperative start time of eating and average postoperative length of hospital stay in the LH group were 150(100-200) ml, 5(4-6) cm, 5(3-6) d, 2(2-2) d and (8±3) d, which were significantly less compared with 300(300-600) ml, 20 (18-20) cm, 8(6-10) d, 3(2-3) d and (12±4) d in the OH group (Z=-5.405,-7.760,-4.366,-3.746;t=-3.608;P<0.05). The hospitalization cost in the LH group was (51±7) thousand yuan, which was significantly higher than (45±10) thousand yuan in the OH group (t=3.198, P<0.05). On the postoperative 1, 3 day, the levels of aspartate aminotransferase (AST) and aspartate aminotransferase (ALT) in the LH group were 94(62-114), 47(42-58) and 116(68-136), 46(39-50) U/L, which were significantly lower than 110(93-158), 152(95-220) and 141(97-236), 49(42-120) U/L in the OH group (Z=-2.416,-6.539,-2.764,-2.229;P<0.05). In the LH group, the serum levels of albumin (ALB) on the postoperative 1, 3 day were (31±6), (35±3) g/L, which were signiifcantly higher compared with (25±5), (34±3) g/L (t=4.958, 2.191;P<0.05). Conclusions LH is an efifcacious and safe treatment for liver neoplasms. Compared with OH, LH has obvious advantages of smaller incision and shorter recovery time.
