目的

探讨乳腺癌前哨淋巴结活检术(sentinel lymph node biopsy,SLNB)的放射安全性。

方法

采用热释光剂量计(thermoluminescent dosimeters,TLD)检测在SLNB 过程中患者乳房注射部位、胸腺、盆腔性腺及医务人员优势手食指、胸腺、盆腔性腺、眼晶体接受的放射线剂量。 2006 年10 月至2007 年7 月连续检测行乳腺单纯切除/保留乳房+SLNB的乳腺癌患者40 例。

结果

患者乳房注射部位的吸收剂量最大(5.946±5.023)mSv,显著高于胸腺及盆腔的吸收剂量(均P =0.000)主刀医师、第一助手、器械护士各部位核素吸收剂量差异无统计学意义(均P﹥0.05),远远低于我国卫生部确定的放射卫生防护基本标准。 依据该标准,术者每年完成约1000 台SLNB手术在放射安全性方面是安全的。

结论

核素法SLNB对患者和医务人员是安全的,不需要进行防护。

Objective

To study the radiologic safety of sentinel lymph node biopsy (SLNB) in breast cancer.

Methods

SLN was detected with methylthionium and99Tcm-sulfur colloid. Thermoluminescent dosimeters (TLD) were used to detect radiation dose received by medical stuff and 40 cases treated with breast conserving surgery or mastectomy and SLNB between October 2006 and July 2007. The TLDs were set at the breast injection site, thoracic gland, and cavitas pelvis gonad of patients, and dominant hand index finger, thoracic gland, cavitas pelvis gonad and ocular lens of medical stuffs.

Results

The mean radiation dose received at the breast injection site (5.946±5.023 mSv) was significantly higher than that at the thoracic gland and cavitas pelvis gonad of the patients (both P =0.000). The mean radiation dose received at different parts of different medical stuff had no statistical significance (all P﹥0.05) , which was far lower than basic criterion of radiological health protection from the Department of Health of China. According to this criterion, it would be safe for surgeons to perform 1000 cases of SLNBs annually.

Conclusions

SLNB in breast cancer is radiological safe both for patients and medical stuffs, and no radiologic protection is necessary during operation.
