“醫(yī)學(xué)閱讀：肝癌”相信是準(zhǔn)備參加全國醫(yī)學(xué)博士外語統(tǒng)一考試的朋友比較關(guān)注的事情，為此，醫(yī)學(xué)教育網(wǎng)小編整理內(nèi)容如下：

liver cancer

there is no consensus regarding the optimal treatment of patients with liver tumors.this contributes to the pessimistic attitude that many have regarding the treatment of liver cancer.aggressive treatment strategies can cure or significantly prolong the life of many patients with liver cancer.

the liver is a common site of metastases from a variety of organs such as lung，breast，colon and rectum.when liver metastases occur at the time of initial diagnosis of the primary tumor，they are described as synchronous.if detected after the initial diagnosis，they are described as metachronous.the liver is frequently involved since it receives blood from the abdominal organs via the portal vein.malignant cells detach from the primary cancer，enter the bloodstream or lymphatic channels，travel to the liver，and grow independently.we do not understand the mechanism of how a tumor cell can leave the primary site and grow in specific organs.potentially，the environment of the liver is suitable to the growth of certain tumor cells.once a tumor begins to grow in the liver，it receives its blood supply from the hepatic artery.

肝癌

對肝癌的治療有分歧。這有利于許多對肝癌治療持悲觀態(tài)度。有創(chuàng)見的治療方案是能治療或延長肝癌病人的生命。

肝是一些器官，如：肺、乳房、結(jié)腸和直腸的共同轉(zhuǎn)移地。在原發(fā)性腫瘤的早期診斷時發(fā)現(xiàn)肝轉(zhuǎn)移，稱作同步。如果在早期診斷后發(fā)現(xiàn)，稱作異步。由于肝通過門靜脈接受腹腔器官來的血液，所以肝常受累。惡性細(xì)胞從原發(fā)癌脫離，通過血流或淋巴管，來到肝獨(dú)立生長。我們不明白一個瘤細(xì)胞是如何離開原發(fā)部位來到特異器官生長的原理。當(dāng)然，肝是適合某些特定瘤細(xì)胞的生長環(huán)境。一旦一個瘤在肝生長繁殖，它接受肝動脈的血供。
