1、乳腺癌肝转移的特点及内科治疗,肝脏的生理特点,药物代谢(在决定抗肿瘤疗效及控制毒性方面具有促进及解毒等作用),肝脏是系统调节营养及激素的重要器官,与生理节律和免疫功能密切相关,肝脏为多个恶性肿瘤(乳腺、肺、肠、前列腺、大脑等)远处转移易发生的靶器官,1.乳腺癌肝转移的概况及预后,2.乳腺癌肝转移的内科治疗,概况-乳腺癌首发转移特点,肝转移 7.3%,肺转移 22.4%,骨转移 41.1%,其他 18.9%,脑转移 7.3%,7.3%,Abigail T.Berman,1 Arpi D.Thukral,et al.Incidence and Patterns of Distant Metasta
