We sought to empirically compare treatment room length-of-stay and patient throughput for recombinant human thyroid-stimulating hormone (rhTSH)-aided thyroid remnant ablation with thyroid hormone withdrawal (THW)-aided ablation in patients with differentiated thyroid carcinoma (DTC).
We retrospectively reviewed charts of all eligible (near) totally thyroidectomized patients with DTC undergoing ablation and 1-year ablation success evaluation at our tertiary referral centre from January 2003 to February 2009 (N=274). M1 disease caused exclusion unless discovered by a postablation scan or present when rhTSH was the only tolerable stimulation method. We extracted data on the length-of-stay, defined as the time between treatment room admission and discharge, and patient throughput, defined as patients ablated per treatment room per week. The treatment room discharge criterion was a whole-body dose rate of less than 60 μSv/h at 50 cm.
The treatment groups (rhTSH, n=187; THW, n=87) had mostly statistically similar characteristics, but differed in primary tumour status distribution. In addition, at ablation, the rhTSH patients had a greater prevalence of prior diagnostic scintigraphy, higher mean serum TSH, and shorter interval since surgery, and received a 5.6% larger mean ablation activity. On average, rhTSH patients had a significantly lower peak whole-body dose rate (57.1 vs. 83.4 μSv/h at 50 cm; P<0.0001) and a significantly shorter treatment room stay than did the THW patients (1.41 vs. 2.02 days; P<0.001). rhTSH use allowed significantly more patients to be ablated per room per week (2.7 vs. 1.2; P<0.001).
Relative to THW, rhTSH use to aid ablation reduced mean treatment room length-of-stay by almost one-third and more than doubled the average weekly patient throughput, both of which were significant differences.
我们试图通过实证比较重组人促甲状腺激素(rhTSH)辅助甲状腺残余消融与甲状腺激素撤停(THW)辅助消融在分化型甲状腺癌(DTC)患者中的治疗室住院时间和患者通量。
我们回顾性分析了2003年1月至2009年2月在我们的三级转诊中心接受消融及1年消融成功评估的所有符合条件的(近)全甲状腺切除的DTC患者的病历(N = 274)。除非在消融后扫描中发现或在rhTSH是唯一可耐受的刺激方法时存在,M1疾病导致排除。我们提取了住院时间的数据,定义为治疗室入院与出院之间的时间,以及患者通量,定义为每个治疗室每周消融的患者数量。治疗室出院标准是在50 cm处全身剂量率低于60 μSv/h。
治疗组(rhTSH,n = 187;THW,n = 87)在大多数情况下具有统计学上相似的特征,但在原发肿瘤状态分布上有所不同。此外,在消融时,rhTSH患者先前诊断性闪烁扫描的患病率更高,平均血清TSH更高,手术间隔时间更短,并且接受的平均消融活度大5.6%。平均而言,rhTSH患者的全身剂量率峰值显著更低(50 cm处为57.1 vs. 83.4 μSv/h;P < 0.0001),并且治疗室停留时间明显短于THW患者(1.41 vs. 2.02天;P < 0.001)。使用rhTSH允许每个房间每周消融的患者明显更多(2.7 vs. 1.2;P < 0.001)。
相对于THW,使用rhTSH辅助消融使平均治疗室住院时间减少了近三分之一,平均每周患者通量增加了一倍多,两者均有显著差异。
