目的进一步探讨结直肠多原发癌和结直肠癌合并其他器官恶性肿瘤的临床特点。方法回顾性分析4178例手术治疗的结直肠癌患者的临床资料。结果本组病例中,同时或异时结直肠多原发癌134例,占3.2%;结直肠癌合并其他器官恶性肿瘤39例,占0.9%。结直肠多原发癌伴结直肠腺瘤96例,占71.6%,以管状腺瘤多见,全结直肠纤维镜检查可使其术前检出率从48.3%(1990年以前)提高到91.4%(1990年以后),1990年后行术后结肠镜检查并及时治疗结直肠腺瘤使术后异时癌的发生率由1.5%降至0.7%。结论结直肠多原发癌和结直肠癌合并其他器官恶性肿瘤发病率较高。应注重术前行全结直肠纤维镜检查,术中全面探查和术后随访。
Objective To further explore the clinical features of multiple primary colorectal cancer and colorectal cancer combined with other organ malignancies. Methods The clinical data of 4178 patients with colorectal cancer underwent surgery were retrospectively analyzed. Results In this group of cases, 134 cases had multiple primary colorectal cancer at the same time or at the same time, accounting for 3.2%. Colorectal cancer combined with other organ malignancies was 39 cases (0.9%). Colorectal multiple primary cancer with colorectal adenomas in 96 cases, accounting for 71.6%, more common tubular adenoma, total colorectal fiboscopy can make its preoperative detection rate from 48.3% (before 1990) to 91.4 % (After 1990), postoperative colonoscopy in 1990 and the timely treatment of colorectal adenoma so that the incidence of heterogenous cancer decreased from 1.5% to 0.7%. Conclusions The incidence of multiple primary colorectal cancer and colorectal cancer with other organ malignancies is high. Should pay attention to preoperative total colorectal fiboscopy, intraoperative exploration and postoperative follow-up.
