Efficacy of sentinel lymph node biopsy in male breast cancer   总被引:10,自引:0,他引:10  
BACKGROUND: Sentinel lymph node biopsy (SLNB) is rapidly becoming the standard of care in the treatment of women with early stage breast cancer. Male breast cancer although relatively rare, has typically been treated with mastectomy and axillary lymph node dissection (ALND). Men who develop breast carcinoma have the same risk as their female counterparts of developing the morbidities associated with axillary dissection. SLNB has been championed as a procedure aimed at preventing those morbidities. We recently have evaluated the role of SLNB in the treatment of men with early stage breast cancer. METHODS: Among the 18 men treated at the University of Michigan Medical Center for breast cancer from May 1998 to November 2002, 6 were treated with SLNB. RESULTS: The mean tumor size was 1.6 cm. The mean patient age was 59.8 years. All of the patients had one or more sentinel lymph nodes identified. Two of the six did not have confirmatory axillary dissection. Three of the six had positive sentinel lymph nodes (50%). Only one of the three patients with a positive sentinel node had more nodes positive. One of the six patients had a positive node on frozen section and underwent immediate complete axillary dissection. This patient had no additional positive nodes. No patients in our series had immunohistochemical studies of the lymph nodes. CONCLUSIONS: Men with early stage breast carcinoma may be offered the management option of SLNB since in the hands of experienced surgeons it has a success rate apparently equal to that in their female counterparts.  相似文献

Introduction

Sentinel lymph node biopsy (SLNB) in cutaneous melanoma (CM) is performed to identify patient at risk of regional and distant relapse. We hypothesized that timing of lymphoscintigraphy may influence the accuracy of SLNB and patient outcomes.

Methods

We reviewed prospective data on patients undergoing SLNB for CM at a large university cancer-center between 2008 and 2015, examining patient and tumor demographics and time between lymphoscintigraphy (LS) and SLNB. Kaplan–Meier survival analysis assessed disease-specific (DSS) and overall-survival (OS), stratified by timing of LS. Cox multivariate regression analysis assessed independent risk factors for survival.

Results

We identified 1015 patients. Median follow-up was 45 months (IQR 26–68 months). Univariate analysis showed a 6.8% absolute DSS (HR 1.6 [1.03–2.48], p = 0.04) benefit and a 10.7% absolute OS (HR 1.64 [1.13–2.38], p = 0.01) benefit for patients whose SLNB was performed < 12 h of LS (n = 363) compared to those performed >12 h (n = 652). Multivariate analysis identified timing of LS as an independent predictor of OS (p = 0.007) and DSS (p = 0.016) when competing with age, sex, Breslow thickness (BT) and SLN status. No difference in nodal relapse rates (5.2% v 4.6%; p = 0.67) was seen. Both groups were matched for age, sex, BT and SLN status.

Conclusion

These data have significant implications for SLNB services, suggesting delaying SLNB >12 h after LS using a Tc99-labelled nanocolloid has a significant negative survival impact for patients and should be avoided. We hypothesise that temporal tracer migration is the underlying cause and advocate further trials investigating alternative, 'stable' tracer-agents.  相似文献

Background

For clinical T1-2N0 breast cancer, sentinel lymph node biopsy (SLNB) has been shown in American College of Surgeons Oncology Group (ACOSOG) Z0011 to be sufficient for women with 1 to 2 positive sentinel lymph nodes with no added benefit for completion axillary lymph node dissection (ALND). Z0011 specified whole breast radiotherapy (RT) using standard tangential fields; however, later analysis showed variation in field design. We assessed nationwide practice patterns and examined factors associated with patients undergoing completion ALND and subsequent radiation field design.

Patients and Methods

Women with clinical T1-2N0 breast cancer who underwent breast-conserving surgery, axillary staging, and whole breast RT in 2012 to 2013 were identified in the National Cancer Database. Multivariable logistic regression modeling was used to examine axillary management and RT, adjusting for demographic and clinicopathologic factors.

Results

Among 83,555 patients meeting criteria, 9.3% underwent upfront ALND, 75.8% underwent SLNB only, and 14.9% underwent SLNB with completion ALND. From 2012 to 2013, upfront SLNB increased from 90.1% to 91.4% (odds ratio, 1.14; P < .001). Among 9474 patients that underwent SLNB with 1 to 2 positive sentinel nodes, 31.2% received completion ALND. Among patients with 1 to 2 positive sentinel nodes, SLNB increased from 65.8% to 72.1% from 2012 to 2013 (P < .001). For patients with 1 to 2 positive lymph nodes that underwent SLNB only, 63.4% underwent breast RT, whereas 36.6% received breast and nodal RT.

Conclusions

Nationwide practice patterns of axillary management vary. Despite an increasing rate of SLNB, many patients still receive upfront and completion ALND. Furthermore, there is significant variation in RT field design, and modern treatment guidelines are warranted for this patient population.  相似文献

BackgroundPerforming sentinel lymph node biopsy (SLNB) in patients with large operable breast cancer is still controversial. Our aim is to find whether or not performing SLNB is feasible and safety in Chinese patients with large operable breast cancer.MethodsWe reviewed the data of patients in our center from 2003 to 2015, a series of 267 patients with large operable breast cancer (≥4 cm) who underwent SLNB were examined. All selected patients recieved preoperative axillary evaluation.ResultsThe successful rate for localizing SLNs was 96.3% (257 of 267). 31.1% (78 of 257) patients were found to have positive sentinel lymph nodes (SLN). The median follow-up was 52 months. 2.2% (4 of 179) SLN-negative patients developed axillary recurrence (AR) as first event. The 5-year axillary recurrence free survival in SLN-negative patients was 96.9% (95%CI, 93.8%–100%). Patients with suspicious nodes on ultrasonography (US) (P = 0.16) and undergoing breast conserving therapy (BCT) (P = 0.057) had a higher trend to be associated with AR. The 5-year recurrence free survival (RFS) was 86.1% (95%CI, 80.8%–93.0%) in SLN-negative patients and 76.3% (95%CI, 68.1%–90.1%) in SLN-positive patients (P = 0.246).ConclusionsSLNB is feasible and safety in patients with large operable breast cancer who underwent preoperative axillary evaluation.  相似文献

目的:探讨前哨淋巴结活检(SLNB)联合术前超声在老年乳腺癌患者治疗中的临床价值。方法:回顾性分析136例老年乳腺癌患者资料,将其分为三组,A组:SLNB+超声组,B组:SLNB组,C组:超声组。分别统计各组检查结果与术前腋窝淋巴结穿刺病理或SLNB的符合情况,分析三组对腋窝淋巴结转移的评价。结果:结果显示A组较B组、A组较C组均准确率高,差异有统计学意义,而B组与C组差异无统计学意义。诊断试验结果显示:SLNB比术前超声的特异度高,误诊率低。灵敏度和漏诊率差距不大。结论:SLNB联合术前超声在老年乳腺癌患者治疗中准确性高,较单独SLNB或术前超声均具有优势,值得在老年乳腺癌腋窝淋巴结转移情况的评估和治疗中推广应用。  相似文献
