摘要
目的:探讨^(99m)Tc-硫胶体(sulfur colloid,SC)用于早期乳腺癌前哨淋巴结(sentinel lymph node,SLN)活检术的最适注射体积。方法:选择原发性乳腺癌(T_(1~2)N_0M_0)、乳房为中小型-致密型患者150例,按^(99m)Tc-SC注射体积不同分为0.5、1、1.5 mL 3组(每组n=50),术前1 d瘤周深部两点法注射(37 MBq/点),2 h后SPECT显像。比较3组患者腋窝SLN(axillary SLN,ASLN)及内乳SLN(internal mammary SLN,IM-SLN)显像检出率。结果:各组总检出率、ASLN检出率和IM-SLN检出率分别为:96%(48/50)、94%(47/50)、74%(37/50),90%(45/50)、82%(41/50)、68%(34/50),52%(26/50)、32%(16/50)、18%(19/50)。总SLN和ASLN检出率在0.5 mL与1 mL组之间无统计学差异,但0.5 mL与1.5 mL组之间有统计学差异(P=0.001和0.004);IM-SLN检出率在0.5 mL组与其他两组之间有显著性差异(P<0.05)。各组注射疼痛评分分别为3.34±1.02、4.58±1.31和5.06±1.42,疼痛持续时间分别为(3.82±1.64)、(6.00±4.48)和(6.58±4.77)min。0.5 mL组疼痛评分、持续时间显著弱于其他两组(P<0.001)。结论:在中小型-致密型乳房患者中,示踪剂注射体积仅为0.5 mL/点即能获得较好的SLN检出率,且对定位IM-SLN有一定优势;同时小体积注射伴随较少的疼痛感,改善了患者舒适度。
Objective： To investigate the optimal injection volume of ^99mTc-sulfur colloid （SC） for sentinel lymph node biopsy in early-stage breast cancer. Methods： A total of 150 early-stage breast cancer patients （T1-2N0M0）（small-medium sized, dense breasts） were enrolled in the study. All patients were given deep injection of 99mTc-SC in two peritumoral points （37 MBq/ point） one day before operation, and assigned to three groups （0.5 mL, 1 mL and 1.5 mL） according to injection volume （n=50 each group）. SPECT was performed 2 h post injection. The detection rates of axillary SLN （ASLN） and internal mammary SLN （IM- SLN） by lymphoscintigraphy in all groups were compared. Results： The overall SLN detection rates were 96% （48/50） in 0.5 mL group, 94% （47/50） in 1 mL group and 74% （37/50） in 1.5 mL group; ASLN detection rates were 90% （45/50）, 82% （41/50） and 68% （34/50）, respectively; IM-SLN detection rates were 52% （26/50）, 32% （16/50） and 18% （9/50）, respectively. There was no significant difference in the overall SLN detection rate and ASLN detection rate between groups 0.5 mL and 1 mL. But there was significant differences between groups 0.5 mL and 1.5 mL （P=0.001 and 0.004）. For IM-SLN detection rate, there were statistical difference between 0.5 mL group and other two groups （P〈0.001）. Injection pain scores were 3.34±1.02, 4.58±1.31, 5.06±1.42, and pain duration were （3.82±1.64）, （6.00±4.48） and （6.58±4.77） min from lower volume group to higher volume group. Group 0.5 mL had lowest injective pain score and shortest pain duration in three groups （P〈0.001）. Conclusion： 0.5 mL/point is the optimal injection volume in small-medium sized dense breasts, with higher SLN detection rate and higher sensitivity in IM-SLN localization. Less injection volume could decrease the pain and improve the comfort degree.
