During the past several decades, there has been a shift in the distribution of colorectal cancer toward the right side, with an increase in colon lesions on the right side and a marked decrease in rectal lesions. In 1,009 cases studied between 1966 and 1977, this change in distribution pattern is illustrated. A revision of widespread current concepts of colonic cancer detection is indicated.
在过去几十年中，结直肠癌的分布已向右侧转移，右侧结肠病变增加，直肠病变显著减少。在1966年至1977年间研究的1009例病例中，这种分布模式的变化得到了体现。这表明目前广泛使用的结肠癌检测概念需要修订。
