英国每年约有12000人患胃癌,5年存活率仅7～10%,近30年来并无多大改善。在日本,早期诊断结合根治手术可使手术治愈率达40%以上。在英国和美国,可手术的50～60%病人可切除原发灶,其中约半数被认为是治愈性的,但有2/3可再次复发,且死于局部病情恶化(87%)和/或远位转移(30%)。40%不能手术的病人预后更差,中位存活期仅4个月。
About 12,000 people in the UK suffer from gastric cancer each year. The five-year survival rate is only 7 to 10%. There has been no significant improvement in the past 30 years. In Japan, early diagnosis combined with radical surgery can result in a surgical cure rate of more than 40%. In the United Kingdom and the United States, 50 to 60% of the patients who can be operated on can undergo primary resection, about half of whom are considered to be curative, but 2/3 of them can relapse again and die from local deterioration (87%) and/or Or distant transfer (30%). A 40% inoperable patient had a worse prognosis, with a median survival of only 4 months.
