CT-guided Hook-wire versus microcoil localization in the pulmonary nodules surgery: A systematic review and meta-analysis / 中国胸心血管外科临床杂志

@# Objective    To systematically evaluate the application effect of CT-guided Hook-wire localization and CT-guided microcoil localization in pulmonary nodules surgery. Methods    The literatures on the comparison between CT-guided Hook-wire localization and CT-guided microcoil localization for pulmonary nodules were searched in PubMed, EMbase, The Cochrane Library, Web of Science, Wanfang, VIP and CNKI databases from the inception to October 2021. Review Manager (version 5.4) software was used for meta-analysis. The Newcastle-Ottawa Scale (NOS) was used to evaluate the quality of studies. Results    A total of 10 retrospective cohort studies were included, with 1 117 patients including 473 patients in the CT-guided Hook-wire localization group and 644 patients in the CT-guided microcoil localization group. The quality of the studies was high with NOS scores>6 points. The result of meta-analysis showed that the difference in the localization operation time (MD=0.14, 95%CI −3.43 to 3.71, P=0.940) between the two groups was not statistically significant. However, the localization success rate of the Hook-wire group was superior to the  microcoil group (OR=0.35, 95%CI 0.17 to 0.72, P=0.005). In addition, in comparison with Hook-wire localization, the microcoil localization could reduce the dislocation rate (OR=4.33, 95%CI 2.07 to 9.08, P<0.001), the incidence of pneumothorax (OR=1.62, 95%CI 1.12 to 2.33, P=0.010) and pulmonary hemorrhage (OR=1.64, 95%CI 1.07 to 2.51, P=0.020). Conclusion    Although Hook-wire localization is slightly better than microcoil localization in the aspect of the success rate of pulmonary nodule localization, microcoil localization has an obvious advantage compared with Hook-wire localization in terms of controlling the incidence of dislocation, pneumothorax and pulmonary hemorrhage. Therefore, from a comprehensive perspective, this study believes that CT-guided microcoil localization is a preoperative localization method worthy of further promotion.

Ultrasonography-guided wire-localization and nano-carbon staining for detection of sentinel lymph node in breast cancer / 肿瘤研究与临床

Objective@#To evaluate the usage of ultrasound guided wire-localization, nano-carbon staining and the combination of the above two methods in detecting sentinel lymph node (SLN) in breast cancer.@*Methods@#A total of 159 cases of breast cancer from May 2015 to December 2017 in Shanxi Provincial Cancer Hospital were selected, and they were treated with ultrasound guided wire-localization, nano-carbon staining and combination of the two methods separately to detect SLN before the operation. After the operation, SLN and axillary lymph node in each group were marked and made pathological diagnosis.@*Results@#There were 69 cases with pathological diagnosis of SLN metastasis and 90 cases without abnormal representation. With the patient as the unit, the sensitivity of ultrasound guided wire-localization was 100.0% (69/69), the sensitivity of nano-carbon staining was 98.6% (68/69), and the sensitivity of combination of the two methods was 97.1% (67/69). The specificity of ultrasound guided wire-localization was 3.3% (3/90), the specificity of nano-carbon staining was 2.2% (2/90), and the specificity of combination of the two methods was 5.6% (5/90). With the count of SLN as the unit, the combination of the two methods had the highest diagnostic efficiency in detecting SLN, and the difference was statistical significant (χ2 = 34.31, P < 0.001).@*Conclusions@#Ultrasound guided wire-localization and nano-carbon staining are safe and accessible methods for detecting SLN. It provides a precise treatment for early breast cancer, and it can protect medical staff from radiation, which is expected to be the best method for detection of SLN in breast cancer.

Clinical application of preoperative ultrasound-guided guide-wire localization in diagnosing tiny breast lesions / 介入放射学杂志

Objective To discuss the clinical application of ultrasound-guided preoperative guide-wire localization in diagnosing tiny breast lesions. Methods A total of 56 patients with impalpable tiny breast lesions were enrolled in this study . Preoperative guide-wire localization of the lesion was performed under high-frequency ultrasound guidance, which was followed by tracking resection of the lesion. The clinical data were retrospectively analyzed. Results Successful localization and complete resection of the lesion was accomplished in all 56 patients. The lesions included invasive ductal carcinoma (n=11), intraductal carcinoma (n=5), ductal carcinoma in situ (n=2), mucinous carcinoma (n=2), fibroadenoma (n=24), atypical hyperplasia (n=6), intraductal papilloma (n=4) and plasma-cell mastitis (n=2). Conclusion Ultrasound-guided preoperative guide-wire localization is a safe and reliable technique for the diagnosis of impalpable tiny breast lesions. It can precisely localize the lesion , which is very helpful for making a complete resection of the lesion and avoiding unnecessary breast injury. Therefore , this technique should be recommended in clinical practice.

Diagnosis and management of non-palpable breast cancer / 中华内分泌外科杂志

ObjectiveTo evaluate the diagnosis and surgical management of non-palpable breast cancer (NPBC). MethodsDiagnosis, preoperative localization and surgical management of 26 cases of NPBC were analyzed retrospectively.ResultsAll the 26 lesions were found by ultrasound or mammography.Local-extensive excision was performed under preoperative ultrasound-guided or radio-guided wire localization.Of the 26 lesions, 14 were ductal carcinoma in situ (DCIS), 9 were DCIS with micro-invasion and 3 were invasive ductal carcinoma.ConclusionsCombination of ultrasound and mammography improves the discovery rate of NPBC.Local-extensive excision under preoperative ultrasound-guided or radio-guided wire localization of NPBC shortens the duration of surgical procedure, avoids excessive resection of breast tissues and maintains the apperance of the breast.

Objective Approach mammographic wire-localization biopsy technology's value in diagnose of dditescenee focus of infection about breast disease. Methods Utilizing specific purpose computer stereotaxis system, utilize mammographic wire-localization for 47 pieces delitescenee focus of infection about breast disease which can't be touehed in clinical ,at guide wire's leading exsect focus of infection and make molybdenum target for tissue by ex- cisional, then make patho-test when the focus of infection were completely resection. Results 45 patients have 47 pieces delitescence focus of infection,detaining 47 guide wire,all operations succeed only by once,and the focus of in- fection are completely resection,the correct rate of diagnose is 100% .The result of patho:13 cases are breast cancer and that have 14 pieces focus of infection,one of them is both sides,benign lesion are 32 cases and 33 pieces focus of infection. Conclusion The biopsy by mammographie wire-localization is convenient and accurate, can make sure the character of delitescence focus of infection about breast disease,which cart raise the rate of diagnosis in earlier period breast cancer.

Localized Biopsy of Nonpalpable Breast Lesions and It’s Role in Early Diagnosis and Treatment of Breast Cancer / 中国普外基础与临床杂志

Objective To evaluate the localized biopsy of nonpalpable breast lesions (NPBLs) and its role in the early diagnosis and treatment of breast cancer. Methods One hundred and fifty-eight NPBLs from a series of 141 women detected by mammography were resected with wire localization technique. Results Forty-two lesions (26.6%, 42/158) in 42 patients were diagnosed with malignant result, including 12(28.6%) patients with stage 0 breast cancer, 24(57.1%) with stageⅠ, 2(4.8%) with stage Ⅱ and 4(9.5%) with stage Ⅲ disease according to American Joint Committee on Cancer (AJCC) staging system(the 6th edition). The contralateral axillary lymph nodes metastasis were found in only one (2.4%) patient with stage Ⅲ disease and the other forty-one patients remained free of recurrent disease at a median follow-up of 31 months.Conclusion The results showed that the most nonpalpable breast cancers detected by mammography were early-stage breast cancers and had good prognosis. The NPBLs should get a localized biopsy in order to facilitate the early diagnosis and treatment of nonpalpable breast cancers.
