经内镜黏膜下剥离术治疗直肠神经内分泌肿瘤的疗效及安全性CSCD

目的探讨经内镜黏膜下剥离术(ESD)治疗直肠神经内分泌肿瘤(RNET)的疗效,并评估其安全性。方法回顾性分析2011年1月—2017年12月在江苏省人民医院行直肠ESD治疗、经病理及免疫组织化学确诊为RNET的80例患者(91处病变)的临床资料,并对患者进行随访。结果所有病变均为完整切除病灶。有症状的患者术后3天~2月症状均有不同程度缓解,无严重术后并发症,标本切缘阳性率20.88%(19/91),切缘可疑阳性率35.16%(32/91)。切除标本最大长径20 mm。单因素分析中,肿瘤长径≥10 mm、肿瘤处于G2级与切缘可疑阳性及阳性相关(P<0.05)。肿瘤处于G2级为切缘可疑阳性及阳性的独立危险因素。仅有1例患者术前证实为RNET。中位随访时间34月,复发率4.40%(4/91)。结论ESD在治疗直径<20 mm的G1级和G2级的RNET患者中具有良好疗效。对于ESD术后显示切缘阳性及可疑阳性的RNET患者,可密切随访暂不实施其他治疗。     

表浅型食管癌经内镜黏膜下剥离术导致非治愈性切除的危险因素及长期生存分析

Objective To identify risk factors of non-curative resection in superficial esophageal cancer (SEC) after endoscopic submucosal dissection and to evaluate the prognosis. Methods We retrospectively analyzed the data of 207 SEC patients who received ESD. The median follow-up was 48 months. Results The en bloc resection rate was 89.25% (191/214), the complete resection rate was 80.84 % (173/214), the curative resection rate was 70.09% (150/214) and the non-curative resection rate was 29.91% (64/214). The maximum long diameter of specimen was 110 mm. Age, gender, tumor size, lesions performance during surgery and operation time were associated with the non-curative resection (P<0.05). Female, lesion diameter≥50mm and poorly performed lesions were identified as significant risk factors for non-curative resection. In the noncurative resection group, there was no difference in cancer-free survival and survival between patients who had no additional treatmeat after ESD and those who underwent surgery or radiotherapy. Conclusion For patients with poor general condition who are not willing to undergo surgery or chemoradiotherapy, regular endoscopy seems to be an option. © 2020, CHINA RESEARCH ON PREVENTION AND TREATMENT.
