AIMS
The purpose of our study was to determine the radiation dose for those who are involved in the sentinel node procedure in breast cancer patients and testing of a theoretical model.
METHODS
We studied 12 consecutive breast cancer patients undergoing breast surgery, and a sentinel node dissection including an axillary lymph node dissection (ALND). We performed measurements on the surgeon, the assistant, the theatre nurse, the pathologist and his assistant.
RESULTS
The measurements on the theatre nurse and both pathologist as his assistant are beneath the detection limit of 10 micro Sv. The highest measured doses are the hands of the surgeon and his assistant (17-61 micro Sv), however the dose limits for hands are higher than for other parts of the body. Taking the dose limits into account the abdominal wall of the surgeon relatively receives the highest dose, with an average of 8.2 micro Sv per procedure.
CONCLUSION
Radiation dose levels are less than the established dose limits for (nonexposed) workers if the number of procedures is restricted to about 100/person/year.
目的
我们研究的目的是确定参与乳腺癌患者前哨淋巴结手术人员的辐射剂量，并测试一个理论模型。
方法
我们研究了12例连续接受乳腺手术的乳腺癌患者，包括前哨淋巴结清扫及腋窝淋巴结清扫（ALND）。我们对外科医生、助手、手术室护士、病理学家及其助手进行了测量。
结果
手术室护士以及病理学家及其助手的测量值低于10微希沃特的检测限。测量到的最高剂量出现在外科医生及其助手的手部（17 - 61微希沃特），不过手部的剂量限值高于身体其他部位。考虑到剂量限值，外科医生的腹壁相对接受的剂量最高，每次手术平均为8.2微希沃特。
结论
如果手术数量限制在每人每年约100次，辐射剂量水平低于（未暴露）工作人员既定的剂量限值。
