我国是肝癌发病率最高的国家之一,每年新发病患者占世界新发病例的42%,每年约11万人死于此病,占世界肝癌死亡人数的53%。在我国大多数原发性肝癌患者往往合并多年慢性乙型肝炎或肝硬化史,肝功能较差或肿瘤位置特殊等,只有10%~15%的患者适合手术,近年来随着体部立体定向放射治疗(Stereotactic Body Radiation Therapy,SBRT)的应用和普及,配合医学影像及计算机的发展,可在原发性肝癌患者实施精确定位、精确计算、精确
China is one of the countries with the highest incidence of liver cancer. Newly occurring cases account for 42% of new cases in the world each year, and about 110,000 people die of this disease each year, accounting for 53% of the world’s liver cancer deaths. Most patients with primary liver cancer in our country often have many years of history of chronic hepatitis B or cirrhosis, poor liver function or tumor location, and only 10% to 15% of patients are suitable for surgery. In recent years, as the body is stereotactic Radiotherapy (Stereotactic Body Radiation Therapy, SBRT) application and popularity, with the medical imaging and computer development, in patients with primary liver cancer precise positioning, accurate calculation, accurate
