肝癌的介紹
肝癌是指發生於肝臟的惡性腫瘤，包括原發性肝癌和轉移性肝癌兩種，人們日常說的肝癌指的多是原發性肝癌。接下來小編爲大家整理了肝癌的介紹，希望對你有幫助哦!
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.
對肝癌的治療有分歧。這有利於許多對肝癌治療持悲觀態度。有創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、結腸和直腸的共同轉移地。在原發性腫瘤的早期診斷時發現肝轉移，稱作同步。如果在早期診斷後發現，稱作異步。由於肝通過門靜脈接受腹腔器官來的血液，所以肝常受累。惡性細胞從原發癌脫離，通過血流或淋巴管，來到肝獨立生長。我們不明白一個瘤細胞是如何離開原發部位來到特異器官生長的原理。當然，肝是適合某些特定瘤細胞的生長環境。一旦一個瘤在肝生長繁殖，它接受肝動脈的血供。
