肝癌的介紹

　　肝癌是指發(fā)生于肝臟的惡性腫瘤，包括原發(fā)性肝癌和轉(zhuǎn)移性肝癌兩種，人們?nèi)粘Ｕf(shuō)的肝癌指的多是原發(fā)性肝癌。接下來(lái)小編為大家整理了肝癌的介紹，希望對(duì)你有幫助哦!

　　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.

　　對(duì)肝癌的治療有分歧。這有利于許多對(duì)肝癌治療持悲觀態(tài)度。有創(chuàng)見(jiàn)的治療方案是能治療或延長(zhǎng)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(shí)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(guò)門(mén)靜脈接受腹腔器官來(lái)的血液，所以肝常受累。惡性細(xì)胞從原發(fā)癌脫離，通過(guò)血流或淋巴管，來(lái)到肝獨(dú)立生長(zhǎng)。我們不明白一個(gè)瘤細(xì)胞是如何離開(kāi)原發(fā)部位來(lái)到特異器官生長(zhǎng)的原理。當(dāng)然，肝是適合某些特定瘤細(xì)胞的生長(zhǎng)環(huán)境。一旦一個(gè)瘤在肝生長(zhǎng)繁殖，它接受肝動(dòng)脈的血供。
