目的 探究老年食管鳞癌患者单纯放疗、同步放化疗临床治疗效果。方法 选我院2018年1月—2020年12月期间90例老年食管鳞癌患者为研究对象,依据不同治疗方式将其分为对照组、观察组,各45例,分别接受单纯放疗、同步放化疗治疗,比较2组治疗效果及治疗安全性。结果 观察组治疗总有效率为75.56%,与对照组60.00%相近(P＞0.05);观察组疾病控制率为97.78%,较对照组84.44%高(P＜0.05);观察组放射性肺炎、骨髓抑制发生率为24.44%、77.78%,较对照组6.67%、48.89%高;且观察组放射性肺炎、骨髓抑制、放射性食管炎2级占比分别为17.78%、35.56%、57.78%,均较对照组2.22%、8.89%、24.44%高(P＜0.05)。结论 在老年食管鳞癌患者治疗中,与单纯放疗相比,同步放化疗可提升疾病控制能力,但会增加治疗不良反应,增加不良反应严重程度,因此在临床治疗中,需慎重选择。

Objective To explore the clinical effect of radiotherapy only and concurrent chemoradiotherapy in elderly patients with esophageal squamous cell carcinoma. Methods Ninety cases of elderly patients with esophageal squamous cell carcinoma in our hospital from January 2018 to December 2020 were selected as research objects.According to different treatment methods, they were divided into control group and observation group, 45 cases in each group.They were treated with radiotherapy and concurrent chemoradiotherapy respectively.The treatment effect and safety of the two groups were compared. Results The total effective rate of the observation group was 75.56%, which was close to the control group (60.00%, P>0.05). The disease control rate of the observation group was 97.78%, which was higher than control group (84.44%, P<0.05). The incidence of radiation pneumonia and bone marrow suppression of the observation group were 24.44% and 77.78%, which were higher than that of the control group (6.67%, 48.89%). The proportion of radiation pneumonia, bone marrow suppression, radiation esophagitis grade 2 of the observation group were 17.78%, 35.78% and 57.78% respectively, higher than that of the control group (2.22%, 8.89%, 24.44% respectively, P<0.05). Conclusion Compared with radiotherapy only, concurrent chemoradiotherapy improved the ability of disease control in elderly patients with esophageal squamous cell carcinoma, but it increased the adverse reactions and aggravated the severity of adverse reactions.Therefore, it is necessary to make a careful choice in clinical treatment.

目的 探讨p27^Kip1蛋白的表达与梅州地区客家人食管鳞癌的关系。方法 收集我院病理科2003年1月—2008年12月的61例经手术切除的中国梅州地区客家人食管鳞癌组织及32例食管良性肿瘤组织为研究对象并包埋成蜡块。采用免疫组织化学技术检测组织中p27^Kip1蛋白的表达,结合患者的临床病理资料和随访资料,进行回顾性分析,并作出评价。结果 P27^Kip1蛋白在食管鳞癌细胞核和/或细胞浆都有表达。胞核表达阳性率为27.87%,低于食管良性肿瘤组织胞核表达（50.0%）（P<0.05）;而胞浆表达阳性率为49.18%,高于食管良性肿瘤组织胞浆表达（12.5%）（P<0.05）。无淋巴结转移的食管鳞癌p27^Kip1蛋白胞核表达阳性率为42.41%,高于有淋巴结转移者的阳性率（10.7%）,差异有统计学意义（P<0.05）;而无淋巴结转移的食管鳞癌p27^Kip1蛋白胞浆表达阳性率为42.4%,比有淋巴结转移者（57.12%）的阳性率有降低的趋势（P>0.05）。Ⅱ期（ⅡA+ⅡB）和Ⅲ期p27Kip1蛋白胞核表达阳性率分别为42.41%和10.71%,差异有统计学意义（P<0.05）;p27^Kip1蛋白胞浆表达阳性率有随着TNM分期的增高而增高的趋势（P>0.05）。结论 P27^Kip1蛋白作为肿瘤抑制因子,其在食管鳞癌的胞核和胞浆表达阳性呈相反趋势,随食管鳞癌TNM分期越高,胞核阳性率越低,胞浆阳性率越高,其可作为食管肿瘤恶性程度及进展的预测指标。
