Interval colorectal cancer (I-CRC) is defined as a CRC diagnosed within 60 months after a negative colonoscopy, taking into account that 5 years is the "mean sojourn time." It is important to prevent the development of interval cancer. The development of interval colon cancer is associated with female sex, old age, family history of CRC, comorbidities, diverticulosis, and the skill of the endoscopist. During carcinogenesis, sessile serrated adenomas/polyps (SSA/Ps) share many genomic and colonic site characteristics with I-CRCs. The clinical and biological features of I-CRC should be elucidated to prevent the development of interval colon cancer.
间期结直肠癌(I-CRC)被定义为在结肠镜检查结果为阴性后的60个月内诊断出的结直肠癌,同时考虑到5年是“平均停留时间”。预防间期癌的发生很重要。间期结肠癌的发生与女性、老年、结直肠癌家族史、合并症、憩室病以及内镜医师的技术有关。在致癌过程中,无蒂锯齿状腺瘤/息肉(SSA/Ps)与I-CRC在许多基因组和结肠部位特征上有共同之处。应阐明I-CRC的临床和生物学特征以预防间期结肠癌的发生。
