老年肺癌的比例逐年提高,山口统计1,662例肺癌住院病例,老年者几乎每年递增1%。有些国家老年肺癌的比例,男女已分别上升到50%与48%。Thomas分析6,686例肺癌后指出,该病的危险性随年龄的增加而增大。近年来,老年肺癌的治疗日益受到重视,尤其外科手术,发展更为迅速。国外报道,高龄组(70岁以上)与超高龄组(80岁以上)肺癌手术的比例,70年代以前仅为0～10%与0～1%。80年代上升到14.5～40.3%与4～24.2%。目前该课题已发展到超高龄肺癌外科治疗的新阶段,服部认为当前的研究重点应放在超高龄肺癌上,池村也认为当代老年肺癌外科已向80岁以上的超高龄方向转移。
The proportion of elderly patients with lung cancer has been increasing year by year. Yamaguchi has recorded 1,662 cases of lung cancer hospitalization, and elderly people have increased by almost 1% each year. In some countries, the proportion of elderly patients with lung cancer has risen to 50% and 48% respectively. Thomas analyzed 6,686 cases of lung cancer and pointed out that the risk of the disease increases with age. In recent years, the treatment of lung cancer in elderly patients has received increasing attention, especially surgery, and it has developed rapidly. According to foreign reports, the proportion of lung cancer surgery in the senior age group (70 years old or older) and the super-old age group (80 years old or older) was only 0 to 10% and 0 to 1% before the 1970s. The 1980s rose to 14.5 to 40.3% and 4 to 24.2%. At present, this topic has been developed into a new stage of surgical treatment for super-old lung cancer. The service department believes that the current research focus should be on super-old lung cancer. Chi Village also believes that the current elderly lung cancer surgery has shifted to the over-age age of 80 years old.
