摘要
目的探讨2001年至2015年结直肠侧向发育型肿瘤(LST)患者的临床病理特征和治疗方法随时间变迁的规律。方法回顾性收集2001年至2015年行内镜下治疗或外科手术的549例结直肠LST患者的病历资料,按诊断的时间顺序分成2001年至2005年、2006年至2010年和2011年至2015年3个时间段,分析其性别、年龄、病灶大小、病变亚型等临床病理特征和治疗手段。统计学方法采用卡方检验。结果2001年至2005年、2006年至2010年、2011年至2015年的结直肠LST检出率分别为0.38%(50/13 319)、0.60%(144/23 912)和0.79%(355/44 715),差异有统计学意义(χ^2=29.34,P〈0.01)。3个时间段男女比例均接近1∶1,患者平均年龄约59岁,LST病灶最大径平均值均维持在30 mm左右。2001年至2005年、2006年至2010年、2011年至2015年颗粒型侧向发育型肿瘤(LST-G)分别占82.4%(42/51)、67.7%(105/155)和78.2%(283/362),非颗粒型侧向发育型肿瘤(LST-NG)分别占17.6%(9/51)、32.3%(50/155)和21.8%(79/362),差异有统计学意义(χ^2=7.77,P=0.02);3个时间段近端结肠LST所占比例分别为21.6%(11/51)、34.2%(53/155)、41.4%(150/362),远端结肠LST则分别为78.4%(40/51)、65.8%(102/155)、58.6%(212/362),差异有统计学意义(χ^2=8.61,P=0.01)。3个时间段黏膜高级别瘤变(HGN)所占比例分别为13.7%(7/51)、21.9%(34/155)、48.6%(176/362),浸润癌所占比例分别为2.0%(1/51)、5.2%(8/155)、8.3%(30/362),差异有统计学意义(χ^2=58.89,P〈0.01)。3个时间段内镜下黏膜切除术(EMR)所占比例分别为56.9%(29/51)、58.7%(91/155)、32.0%(116/362),内镜下分片黏膜切除术(EPMR)所占比例分别为41.2%(21/51)、23.9%(37/155)、14.1%(51/362),内镜下黏膜剥离术(ESD)所占比例分别为0、12.3%(19/155)、46.1%(167/362),手术治疗所占比例为0、5.2%(8/155)、7.7%(28/362),差异有统计学意义(χ^2=112.46,P〈0.01)。结论2001年至2015年,结直肠LST的临床病理特征和治疗方法随时间发生了变迁。近端结肠LST构成比增高,LST-G比例下降,手术方式转变为以ESD为主,术后黏膜HGN和浸润癌的病理诊断比例增高。
Objective To explore clinical pathological characteristics and treatment changed with time in patients with colorectal laterally spreading tumors (LST) from 2001 to 2015. Methods The clinical data of 549 patients with colorectal LST who received endoscopic resection or surgical operation between 2001 and 2015 were retrospectively collected. According to the time of diagnosis, patients were divided into 2001 to 2005, 2006 to 2010 and 2011 to 2015 groups. The gender, age, lesion size and lesion subtypes, clinical pathologic features and their therapeutic methods were analyzed. Chi-square test was used for statistical analysis. Results The detective rates of colorectal LST in 2001 to 2005 period, 2006 to 2010 period and 2011 to 2015 period were 0. 38% (50/13 319), 0. 60%(144/23 912) and 0. 79%(355/44 715), respectively, and the differences were statistically significant (χ^2 = 29.34, P=0.01). During these three period, the male to female ratio was about 1:1, mean age about 59 years old, and the mean maximum diameter of the LST lesions remained about 30 mm. The percentages of granular type laterally spreading tumor (LST-G) in 2001 to 2005 period, 2006 to 2010 period and 2011 to 2015 period were 82.4%(42/51), 67.7%(105/155) and 78.2%(283/262), respectively; while those of non-granular type laterally spreading tumor (LST-NG) were 17. 6% (9/51), 32. 3% (50/155) and 21. 8% (79/362), respectively; and the differences were statistically significant (χ^2= 7.77, P= 0.02). The proportions of LST located at the proximal colon in the three periods were 21.6%(11/51), 34.2%(53/155) and 41.4% (150/362), respectively; while the percentages of LST at distal colon were 78.4 % (40/51), 65.8 % (102/ 155) and 58.6 ~ (212/362), respectively; and the differnees were statistically significant (χ^2=8.61, P= 0.01). The percentages of high grade neoplasia (HGN) in the three periods were 13.7% (7/51) ,21. 9%(34/155) and 48.6 % ( 176/362), respectively ; while the percentages of invasive carcinoma were 2.0 % (1 / 51) ,5.2% (8/155) and 8. 3% (30/362), respectively; and the differnces were statistically significantly (χ^2= 58.89,P〈0. 01). The percentages of endoscopic mucosal resection (EMR) in the three periods were 56.9%(29/51), 58. 7%(91/155) and 32. 0% (116/362), respectively; the percentages of endoscopic piecemealmucosal resection (EPMR) were 41. 2%(21/51), 23. 9% (37/155) and 14. 1%(51/362), respectively; the percentages of endoscopic submueosal dissection (ESD) were 0, 12.3% (19/155) and 46.1%(167/362), respectively; the percentages of surgical operation were 0, 5.2%(8/155) and 7.7% (28/362), respectively; and the differences were statistically significant (χ^2= 112. 46, P〈 0. 01). Conclusions From 2001 to 2015, the clinical pathological features and therapeutic methods of colorectal LST changed along with time. The proportion of colorectal LST located at proximal colon increased, and the percentage of LST-G decreased. ESD became the primary treatment, and the proportion of pathological diagnosis of HGN and invasive carcinomas increased after operation.
