目的探讨彩超引导下经皮粗针穿刺活检(core needle biopsy,CNB)在乳腺癌术前化疗中的价值。方法用16g全自动活检枪(16g粗针)在彩超引导下经皮穿刺活检96例患者的乳腺病灶,并作免疫组化检测。结果选择96例乳腺癌,患者中93例术前粗针活检的病理组织学分型与术后对照相一致,符合率为96.8%,并全部取得免疫组化检测结果。13例患者出现局部瘀斑,余未发现其他并发症。结论彩超引导下16g粗针活检具有安全、创伤小,病理组织学诊断准确率高等优点,可为乳腺癌术前辅助化疗提供重要依据。
Objective To investigate the value of percutaneous needle biopsy (CNB) guided by color Doppler ultrasonography in the preoperative chemotherapy of breast cancer. Methods 96 cases of breast lesions were percutaneously biopsy guided by color Doppler ultrasonography using a 16g automatic biopsy gun (16g thick needle) and immunohistochemically detected. Results Ninety-six cases of breast cancer were selected. The histopathological types of 93 cases of preoperative needle biopsy were consistent with those of the control group. The coincidence rate was 96.8%. All the immunohistochemical results were obtained. 13 cases of local ecchymosis, I found no other complications. CONCLUSION: The 16g needle biopsy guided by color Doppler ultrasonography has the advantages of safety, less trauma and higher diagnostic accuracy of pathology and histology. It can provide an important basis for preoperative adjuvant chemotherapy for breast cancer.
