    • 摘要: 目的:探讨甲状腺癌患者术后一周血清T3、T4、TSH指标变化意义。方法:选取全甲状腺切除术甲状腺癌术后患者60例为A组,并按照1∶1配比选择60例甲状腺患侧腺叶及峡部切除术甲状腺癌患者为B组,进行研究,并选择健康体检人群60例为对照组。分别比较A、B两组患者术后一周血清总三碘甲腺原氨酸(T3)、甲状腺素血清总甲状腺素(T4)、促甲状腺激素(TSH)指标与对照组的变化。结果:A组患者术后T3和T4与术前对比呈先下降,在第4 d上升后,又下降的趋势,TSH则在术后第1 d下降后呈现持续上升趋势,与对照组和术前对比均差异有统计学意义(P<0.05);B组患者术后T3与术前对比呈持续下降趋势,T4先呈下降趋势,在第4 d和第7 d呈上升趋势,TSH在术后第1 d呈下降趋势后持续上升,与术前对比差异有统计学意义(P<0.05)。且两组术前、术后第1 d~7 d与对照组对比差异有统计学意义(P<0.05)。结论:甲状腺癌患者术后一周血清T3、T4、TSH指标变化呈动态变化趋势,对患者疾病治疗有着重要意义,为医生给予TSH抑制治疗,从而获得较好治疗效果,从而避免出现甲状腺功能异常,可大大提高诊断效率。

    • 摘要: BACKGROUND For advanced gastric cancer patients with pancreatic head invasion,some studies have suggested that extended multiorgan resections(EMR)improves survival.However,other reports have shown high rates of morbidity and mortality after EMR.EMR for T4b gastric cancer remains controversial.AIM To evaluate the surgical approach for pT4b gastric cancer with pancreatic head invasion.METHODS A total of 144 consecutive patients with gastric cancer with pancreatic head invasion were surgically treated between 2006 and 2016 at the China National Cancer Center.Gastric cancer was confirmed in 76 patients by postoperative pathology and retrospectively analyzed.The patients were divided into the gastrectomy plus en bloc pancreaticoduodenectomy group(GP group)and gastrectomy alone group(GA group)by comparing the clinicopathological features,surgical outcomes,and prognostic factors of these patients.RESULTS There were 24 patients(16.8%)in the GP group who had significantly larger lesions(P<0.001),a higher incidence of advanced N stage(P=0.030),and less neoadjuvant chemotherapy(P<0.001)than the GA group had.Postoperative morbidity(33.3%vs 15.3%,P=0.128)and mortality(4.2%vs 4.8%,P=1.000)were not significantly different in the GP and GA groups.The overall 3-year survival rate of the patients in the GP group was significantly longer than that in the GA group(47.6%,median 30.3 mo vs 20.4%,median 22.8 mo,P=0.010).Multivariate analysis identified neoadjuvant chemotherapy[hazard ratio(HR)0.290,95%confidence interval(CI):0.103–0.821,P=0.020],linitis plastic(HR 2.614,95%CI:1.024–6.675,P=0.033),surgical margin(HR 0.274,95%CI:0.102–0.738,P=0.010),N stage(HR 3.489,95%CI:1.334–9.120,P=0.011),and postoperative chemoradiotherapy(HR 0.369,95%CI:0.163–0.836,P=0.017)as independent predictors of survival in patients with pT4b gastric cancer and pancreatic head invasion.CONCLUSION Curative resection of the invaded pancreas should be performed to improve survival in selected patients.Invasion of the pancreatic head is not a contraindication for surgery.

    • 摘要: 目的 分析微波消融术(MWA)治疗甲状腺良性结节的临床疗效及对患者血清三碘甲状腺原氨酸(T3)、甲状腺素(T4)、促甲状腺激素(TSH)水平的影响.方法 选取2017年6月~2019年5月成都医学院第一附属医院、四川大学华西医院及西部战区总医院收治的102例甲状腺良性结节患者为研究对象,随机分为观察组(n=51)与对照组(n=51),观察组行MWA,对照组行甲状腺结节切除术.比较两组手术情况,记录观察组术后6个月内结节消退情况,比较两组治疗前后甲状腺功能(T3、T4及TSH)及并发症发生率.结果 观察组手术时间、术后住院时间短于对照组(P<0.05);术后,观察组甲状腺结节体积不断缩小(P<0.05),且3、6个月甲状腺结节体积缩小率分别为30.45%、79.70%;治疗后,两组T3、T4下降,TSH水平增加,且观察组治疗后血清T3、T4低于对照组,TSH水平明显高于对照组(均P<0.05);观察组并发症发生率较对照组低(P<0.05).结论 MWA治疗甲状腺良性结节疗效较好,可有效保留患者甲状腺功能,促进结节消退,且创伤小,术后并发症发生率低,可在临床推广应用.

    • 摘要: BACKGROUND T4 esophageal cancer portends a poor prognosis,particularly when it is complicated by a tracheoesophageal fistula(TEF)either resulting from disease or occurring as a complication of treatment.Patients with TEF that occurs during treatment are commonly treated with palliative intent because fistula-associated treatment complications such as aspiration pneumonia and mediastinitis are associated with high morbidity and mortality.To date,there is no clear evidence on the optimal treatment of T4 esophageal cancer,particularly when a TEF formation occurs.CASE SUMMARY A 67-year-old gentleman who presented with dysphagia and weight loss.Endoscopy and imaging revealed a T4N1M0 cervical esophageal squamous cell carcinoma.He received image-guided intensity-modulated radiation therapy,with concurrent weekly carboplatin(area under curve 2 mg/mL per minute)and paclitaxel(50 mg/m2 of body surface area).One week after treatment initiation(16.2 Gy thus far),he developed cough on swallowing.A TEF was detected on image-guided radiation therapy using cone-beam computed tomography during the treatment course,for which a tracheal stent was inserted.After discussing the risks and morbidity of continuing treatment,he resumed chemoradiotherapy with an additional radiation dose of 45 Gy in 25 fractions.Three months after completion of chemoradiotherapy,he developed an esophageal stricture that required esophageal stenting and dilatation.The patient remains cancer-free at two year on follow-up.Complete response of esophageal cancer was evident on post-treatment endoscopy and computed tomography imaging,with successful closure of TEF.CONCLUSION This case highlights that successful curative treatment for esophageal cancer complicated by a TEF is possible using novel chemotherapeutic regimens and modern radiation technologies.
