乳腺癌新辅助化疗后前哨淋巴结活检术的研究

目的 探讨乳腺癌病人新辅助化疗后前哨淋巴结活检的可行性。方法对2003年11月至2004年10月住院治疗中的57例Ⅱ、Ⅲ期乳腺癌病人行新辅助化疗后，临床检查腋窝淋巴结阴性行前哨淋巴结活检术（SLNB）。结果57例中检出前哨淋巴结（SLN）53例，检出率93．0％。SLN对腋窝淋巴结状况预测的敏感性为89．7％，特异性为100．0％，准确性为94．3％，阳性预测值为100．0％，阴性预测值为88．9％，假阴性率为5．7％。肿瘤对化疗反应为CR（完全缓解）、PR（部分缓解）和SD（稳定）的SLN检出率分别为100．0％、96．7％和70．0％（P〈0．01）。SLN假阴性3例均为腋窝淋巴结转移数〉4个者。结论Ⅱ、Ⅲ期乳腺癌实施新辅助化疗后。行SLNB可获得与早期乳腺癌SLNB相似的效果。     

乳腺癌新辅助化疗后前哨淋巴结分析的研究进展

腋窝淋巴结清扫术（ALND）作为评估腋窝淋巴结状态的金标准常应用于乳腺癌手术中。但随着医疗技术的发展,在保证生存率及尽量减少复发的前提下,临床上越来越重视患者的生存质量。ALND也因其会造成手臂淋巴水肿、肩部功能障碍等副作用,使用率逐渐下降,取而代之的是创伤更小、使患者的生活质量更好的前哨淋巴结活检术（SLNB）,SLNB也是早期浸润性乳腺癌患者腋窝淋巴结处理的标准方式。新辅助化疗（NAC）作为全身系统治疗重要组成部分,不仅可以缩小肿瘤,增加手术机会,还可以增加保乳率,为更多患者带来临床获益。但NAC后的SLNB因受NAC对淋巴管等作用的影响,存在检出率低及假阴性率（FNR）高的问题,这也使NAC后行SLNB备受争议,如何使更多符合标准的乳腺癌人群豁免ALND获得临床获益是亟待解决的临床问题。目前已有多种技术方法尝试用于提高乳腺癌NAC后SLNB检出率及降低FNR。相比单一示踪剂,联合蓝染料及核素两种传统示踪剂或结合纳米碳混悬液、吲哚菁绿、微泡超声造影、超顺磁氧化铁等新型示踪剂,或是采用纳米颗粒辅助腋窝分期对前哨淋巴结进行示踪,可显著提高SLNB的检出率。多项大型前瞻性试验证明,保证≥3枚前哨淋巴结被切除可显著降低SLNB的FNR;靶向ALND作为SLNB的补充,通过在术前对阳性淋巴结进行标记定位可实现精准切除淋巴结,利用雷达反射器、碳文身、放射性粒子、磁性粒子、术中超声等进行定位可进一步提高其准确性。另外,有研究提出结合影像检查如腋窝超声图像、CT淋巴成像等,能清楚显示淋巴结及其周围淋巴管解剖结构,增加临床医师的把握度,进一步提高检出率,降低FNR,但暂未得到大型试验数据证实。笔者对目前NAC后的前哨淋巴结分析的相关研究进行系统总结,旨在为临床提供思路和方向,关于在临床上具体如何抉择能使更多患者获益未来仍需大量研究来验证。     

乳腺癌新辅助化疗后局部区域外科处理进展

目的探讨乳腺癌新辅助化疗后对局部区域的外科处理策略。方法对近年来有关乳腺癌新辅助化疗降期后保乳治疗、同侧乳房复发的相关因素、原发肿瘤病理退缩模式以及前哨淋巴结活检等局部区域的外科处理的相关文献进行综述。结果①新辅助化疗可使乳腺原发肿瘤降期,提高保乳手术的比率,但通过新辅助化疗降期后保乳手术患者可能存在较高的同侧乳腺肿瘤复发风险。目前比较趋于一致的影响新辅助化疗降期后保乳治疗的同侧乳腺肿瘤复发率的相关因素为残余肿瘤呈多中心模式、残余肿瘤直径〉2cm。新辅助化疗后原发肿瘤病理退缩模式及相关因素尚不明确。②新辅助化疗前、后前哨淋巴结活检（SLNB）均是可行的并获得指南与专家共识的认可,初始腋窝淋巴结阴性患者更能从新辅助化疗后SLNB中获益,初始腋窝淋巴结阳性患者新辅助化疗转阴性后行SLNB替代ALND的前景可期,但需要获得临床认可的成功率和假阴性率及与ALND相似的局部区域复发率及总生存率。结论无论乳腺癌新辅助化疗的临床和影像学疗效如何,外科处理仍然是目前降低局部区域复发风险的重要治疗手段。分子分型时代,我们可以依据乳腺癌初始分期及新辅助化疗的疗效对乳腺癌患者施行个体化的局部区域外科处理     

联合吲哚菁绿荧光法与蓝染法行乳腺癌前哨淋巴结活检的临床研究

目的:探讨联合应用吲哚菁绿(ICG)荧光示踪法与蓝染法行乳腺癌前哨淋巴结活检(SLNB)的可行性。方法:选择2014年3月―2015年10月期间276例乳腺癌患者,其中131例患者应用ICG联合美蓝行SLNB(联合组),145例患者以美蓝为示踪剂行SLNB(美蓝组)。所有患者SLNB结束后均行I、II水平腋窝淋巴清扫。结果:两组基本临床资料差异无统计学意义(均P0.05);联合组前哨淋巴结(SLNs)检出率明显高于美蓝组(96.9 vs.89.7%,P=0.017),平均检出SLNs数目明显多于美蓝组(3.0枚vs.2.1枚,P=0.011);假阴性率低于美蓝组(7.1% vs.10.9%),但差异无统计学意义(P=0.813)。全组数据统计分析显示,SLNs检出个数≤2时的假阴性率明显高于SLNs检出个数≥3时假阴性率(17.5% vs.2.1%,P=0.033)。结论:ICG荧光示踪法联合蓝染法行乳腺癌SLNB相对于蓝染法有检出率高、SLNs平均检出个数多、淋巴管实时显像的优势,在不具备核素法广泛应用条件时推荐使用。     

纳米炭混悬液在乳腺癌前哨淋巴结活检中的应用分析

目的研究纳米炭混悬液(卡纳琳)在乳腺癌前哨淋巴结活检(sentinel lymph node biopsy,SLNB)中的应用价值。方法回顾性分析我院乳腺外科收治的124例乳腺癌患者的临床资料,将其中100例乳腺癌患者随机分成2组,实验组50例,以纳米炭混悬液作为示踪剂;对照组50例,以放射性核素联合美蓝作为示踪剂。全部患者SLNB后常规行腋窝淋巴结清扫术(axillary lymph node dissection,ALND)。术后检验其检出率、准确率、灵敏度、假阴性率。另24例患者以纳米炭混悬液示踪行SLNB后,如前哨淋巴结(SLN)阳性,则继续行ALND;如SLN阴性,则"保腋窝"。根据患者选择术式的不同对比其手术效果及预后。结果实验组与对照组患者前哨淋巴结检出率、准确率、灵敏度、假阴性率比较,差异无统计学意义(P0.05)。结论纳米炭混悬液示踪SLNB可准确预测早期乳腺癌患者的淋巴结状态,较行ALND患者有更少的并发症。     

《中国临床肿瘤学会乳腺癌诊疗指南2018.V1》外科问题解读

新辅助化疗是局部晚期乳腺癌或炎性乳腺癌的规范疗法,可以使肿瘤降期以利于手术或将不可能手术转变为可以手术,一般应按照既定化疗方案周期数（6～8个周期）内最大疗效的原则进行。新辅助化疗后的保乳与常规保乳术后局部复发率间差异无统计学意义,新辅助化疗后保乳切除范围应根据肿瘤初始状况、分子亚型、肿瘤化疗后退缩模式等综合考虑,切缘阴性是基本原则。新辅助化疗后的前哨淋巴结活检（SLNB）争议较多,对cN0病人新辅助化疗前后均可行SLNB,对于cN1-cN0病人可以考虑在双示踪剂、增加淋巴结检出数目、免疫组化病理学检查、应用标记夹等方法有效降低假阴性率（FNR）后行SLNB。Ⅳ期乳腺癌原发灶切除是否改善生存尚存争议,手术应在全身治疗有效的基础上进行,现阶段转移灶手术的主要目的是改善病人生存质量。     

应用亚甲蓝行乳腺癌前哨淋巴结活检276例分析

目的 探讨以亚甲蓝作为示踪剂行乳腺癌前哨淋巴结(SLN)活检的临床应用及影响因素.方法 分析了276例临床T1-T2 N0-M0乳腺癌患者前哨淋巴结活检(SLNB)结果,对SLN检出率及假阴性率影响因素进行了初步分析.结果 276例患者中,成功检出SLN者246例(检出率为89.1%).共检出SLN 423枚,每例1～4枚.前哨淋巴结对腋窝淋巴结转移情况预测的敏感性为77.3%(68/88),假阴性率为8.1%(20/246),假阳性率为0,准确率为91.9%(226/246).临床T2N0M0SLNB成功率高于临床T1N0M0乳腺癌患者(P=0.046);年龄<50岁者SLNB检出成功率高于年龄≥50岁病例(P=0.000),SLNB假阴性率年龄<50岁者显著低于高龄患者(P=0.037);外上象限和外下象限肿瘤SLNB检出成功率明显高于其他象限(P=0.000).内上象限肿瘤SLNB假阴性率高于外上及外下象限(P=0.018).临床TMN分期、EB、PR表达情况及病理类型对SLNB成功率及假阴性率无影响.结论 以亚甲蓝作为示踪剂行乳腺癌SLNB,患者年龄、临床TNM分期、肿瘤部位对SLN检出率有一定影响,患者年龄、肿瘤部位可影响SLNB假阴性率.     

新辅助化疗后乳腺癌保乳手术问题现状

目的探讨新辅助化疗后乳腺癌的病灶退缩模式及其影像学评估方式,新辅助化疗后行保乳手术的适应证,病灶切除范围、切缘选择、前哨淋巴结活检术(SLNB)及腋窝淋巴结处理问题。方法检索国内外关于新辅助治疗后保乳手术的相关文献并作综述。结果新辅助化疗后行保乳手术提高了保乳手术率,改善了乳腺癌患者术后的生活质量,同时其总生存率较乳房全切除者无明显差异。新辅助化疗后肿瘤的退缩模式及其相关因素尚待进一步研究。目前新辅助化疗后保乳手术的适应证仍然主要参考早期乳腺癌的保乳适应证,病灶切除范围则更倾向于按化疗后肿瘤病灶范围,广泛接受的切缘阴性为切缘没有肿瘤细胞累及。SLNB及根据SLNB结果处理腋窝淋巴结在新辅助化疗后保乳手术中的应用尚存在部分争议,从总体来讲SLNB仍被认为是有必要的,但应充分保障活检技术的准确性。结论目前新辅助化疗后保乳手术被认为是安全和有效的,但需在与患者充分沟通局部复发率、规范的局部治疗、术后标准放疗、全身辅助治疗、定期随访等多项保障下慎重进行。     

Sentinel lymph node biopsy examination for breast cancer patients with clinically negative axillary lymph nodes after neoadjuvant chemotherapy

BACKGROUND: The feasibility and accuracy of sentinel lymph node (SLN) biopsy examination for breast cancer patients with clinically node-negative breast cancer after neoadjuvant chemotherapy (NAC) have been investigated under the administration of a radiocolloid imaging agent injected intradermally over a tumor. In addition, conditions that may affect SLN biopsy detection and false-negative rates with respect to clinical tumor response and clinical nodal status before NAC were analyzed. METHODS: Seventy-seven patients with stages II and III breast cancer previously treated with NAC were enrolled in the study. All patients were clinically node negative after NAC. The patients then underwent SLN biopsy examination, which involved a combination of intradermal injection over the tumor of radiocolloid and a subareolar injection of blue dye. This was followed by standard level I/II axillary lymph node dissection. RESULTS: The SLN could be identified in 72 of 77 patients (identification rate, 93.5%). In 69 of 72 patients (95.8%) the SLN accurately predicted the axillary status. Three patients had a false-negative SLN biopsy examination result, resulting in a false-negative rate of 11.1% (3 of 27). The SLN identification rate tended to be higher, although not statistically significantly, among patients who had clinically negative axillary lymph nodes before NAC (97.6%; 41 of 42). This is in comparison with patients who had a positive axillary lymph node before NAC (88.6%; 31 of 35). CONCLUSIONS: The SLN identification rate and false-negative rate were similar to those in nonneoadjuvant studies. The SLN biopsy examination accurately predicted metastatic disease in the axilla of patients with tumor response after NAC and clinical nodal status before NAC. This diagnostic technique, using an intradermal injection of radiocolloid, may provide treatment guidance for patients after NAC.     

临床腋淋巴结阴性乳腺癌前哨淋巴结研究

目的：探讨前哨淋巴结活检术（ｓｅｎｔｉｎｅｌ ｌｙｍｐｈ ｎｏｄｅ ｂｉｏｐｓｙ, ＳＬＮＢ）在乳腺癌治疗中的应用。方法：使用专利蓝和美蓝染色,对１９９９年９月～２００１年４月连续收治的１４５例临床查体腋窝淋巴结阴性乳腺癌病人行前哨淋巴结活检术。结果：ＳＬＮＢ成功率为９６．５％（１４０／１４５）,假阴性率为２３．５％,准确率为９１．４％。病人年龄、肿瘤最大径、肿瘤部位、注射染料类型及是否活检对成功率和假阴性率无影响。结论：ＳＬＮＢ能够准确预测腋窝淋巴结的转移状况,在缩小手术范围、减少术后并发症的同时,提高了腋窝淋巴结分期的准确性;美蓝与专利蓝均可成功确定ＳＬＮ。     

Sentinel Lymph Node Biopsy After Neoadjuvant Chemotherapy Is Accurate in Breast Cancer Patients with a Clinically Negative Axillary Nodal Status at Presentation

Background In breast cancer, neoadjuvant chemotherapy (NAC) is widely used in order to enable a conservative surgery. In patients treated with NAC, the use of sentinel lymph node (SLN) biopsy, which is a good predictor of the axillary nodal status in previously untreated patients, is still discussed. The aim of our study was to determine clinicopathological factors that may influence the accuracy of SLN biopsy after NAC. Methods Between March 2001 and December 2006, 129 patients with infiltrating breast carcinoma were studied prospectively. Preoperatively, all of them underwent NAC. At surgery, SLN biopsy followed by axillary lymph node (ALN) dissection was performed. Lymphatic mapping was done using the isotope method. Results The SLN identification rate was 93.8% (121/129). Fifty-six out of the 121 successfully mapped patients had positive ALN. Eight out of these 56 patients had tumor-free SLN (false-negative rate of 14.3%). The false-negative rate was correlated with larger tumor size (T1-T2 versus T3; P = 0.045) and positive clinical nodal status (N0 versus N1-N2; P = 0.003) before NAC. In particular, the false-negative rate was 0% (0/29) in N0 patients and 29.6% (8/27) in N1-N2 patients. Clinical and pathological responses to NAC did not influence the accuracy of SLN biopsy. Conclusion Our results show that clinical nodal status is the main clinicopathological factor influencing the false-negative rate of SLN biopsy after NAC for breast cancer. SLN biopsy after NAC can predict the ALN status with a high accuracy in patients who are clinically lymph node negative at presentation.     

前哨淋巴结检测在乳腺癌治疗中的意义

目的评价前哨淋巴结活检术 (sentinellymphnodebiopsy,SLNB)预测腋淋巴结肿瘤转移的准确性及其临床意义。方法使用专利蓝染色法和 /或99mTc标记的硫胶体示踪法对我院收治的81例乳腺癌患者进行前哨淋巴结活检。两种方法联合检测 3例前哨淋巴结 (sentinellymphnode ,SLN)均阴性者未行腋淋巴结清扫术。结果 81例患者SLN总检出率为 96 3% (78/81) ,总准确率为97 5 % ,总假阴性率 9 7%。 5 3例单纯染色法检出率为 92 5 % ,准确率 94 2 % ,假阴性率 15 8% ;2 8例99mTc示踪法和 /或染色法联合检测结果分别为 10 0 % ,10 0 %和 0。结论SLNB能够准确预测腋窝淋巴结的转移状况。两种方法联合检测为最佳。术前化疗对假阴性率可能有影响。     

γ探测仪在乳腺癌前哨淋巴结定位活检中的应用

目的:探讨γ探测仪在临床腋窝淋巴结阴性乳腺癌前哨淋巴结定位活检术(SLNB)中的临床应用价值.方法:利用99m锝-右旋糖酐(99mTc-DX)作为前哨淋巴结(SLN)示踪剂,应用γ探测仪定位对29例临床腋窝淋巴结阴性乳腺癌病人实施SLNB,随后进行常规腋窝淋巴清扫术,分析SLNB对腋窝淋巴结转移状态的预测价值.结果:本组SLN转移率为41.67%,非SLN转移率仅为22.54%,两者有明显差异(P＜0.001).在19例常规病理SLN阴性病人中,连续切片发现2例SLN微转移.在12例SLN癌转移中,5例(41.66%)SLN为惟一的转移部位.有1例SLN阴性病人"跳跃转移".本组SLN的敏感性为92.31%,特异性为94.12%,假阴性为7.69%,准确率达96.55%.结论:SLN能准确反映早期乳腺癌腋窝淋巴结转移状态,连续切片能提高SLNB的准确性.     

Comparison of vital dye-guided lymphatic mapping and dye plus gamma probe-guided sentinel node biopsy in breast cancer

The optimal technique for sentinel lymph node biopsy (SLNB) is still debated. SLNB with peritumoral injection of Patent blue dye was performed in 129 clinically T1-T2 and N0 breast cancers in 127 patients (group A); it was later replaced by combined dye and radiocolloid-guided SLNB preceded by lymphoscintigraphy in 72 breast cancer patients (group B). This study compares these two methods. All patients underwent completion axillary dissection. Means of 1.4 and 1.3 SLNs were identified in groups A and B, respectively. The mean number of non-SLNs for the whole series was 14.9 (range 5-42). The first 53 cases of lymphatic mapping (dye only) comprised the institutional learning period during which the identification rate of at least 1 SLN in 30 consecutive attempts reached 90%. The identification rate for the subsequent 76 group A patients was 92%. The accuracy rate of SLNBs for overall axillary nodal status prediction and the false-negative rate for group A patients (after excluding the learning-phase cases) were 93% and 10%, respectively. All 72 group B cases had at least one SLN identified, and only one false-negative case occurred in this group (accuracy and false-negative rates of 99% and 3%, respectively). Both the dye-only and the combined SLNB methods are suitable for SLN identification, but the latter works better and results in higher accuracy, a higher negative predictive value, and a lower false-negative rate. It is therefore the method of choice.     

Reoperative sentinel lymph node biopsy in patients with locally recurrent breast cancer

BACKGROUND: Sentinel lymph node biopsy (SLNB) is considered a standard of care in the staging of breast cancer. The objective was to examine our experience with reoperative SLNB. METHODS: We identified 19 patients in our breast cancer database who had a SLNB in the reoperative setting. All 19 patients had undergone previous breast-conserving surgery with either an axillary lymph node dissection or an SLNB. The reoperative sentinel lymph node (SLN) was identified using blue dye, radioisotope, or both. RESULTS: The SLN was identified in 84% of the reoperative cases. Of these successful cases, both blue dye and radioisotope were used in five cases, and radioisotope alone was used in 11 cases. Radioisotope identified the SLN in the 100% of successful SLNB cases (P = .0003). There were 3 unsuccessful cases in which blue dye and radioisotope failed to identify the sentinel node. CONCLUSIONS: Reoperative SLNB after previous axillary surgery is technically feasible.     

Sentinel lymph node biopsy for breast cancer using methylene blue dye manifests a short learning curve among experienced surgeons: a prospective tabular cumulative sum (CUSUM) analysis

Background  

The benefits of sentinel lymph node biopsy (SLNB) for breast cancer patients with histologically negative axillary nodes, in whom axillary lymph node dissection (ALND) is thereby avoided, are now established. Low false negative rate, certainly with blue dye technique, mostly reflects the established high inherent accuracy of SLNB and low axillary nodal metastatic load (subject to patient selection). SLN identification rate is influenced by volume, injection site and choice of mapping agent, axillary nodal metastatic load, SLN location and skill at axillary dissection. Being more subject to technical failure, SLN identification seems to be a more reasonable variable for learning curve assessment than false negative rate.     

Evaluation of the benefit of using blue dye in addition to radioisotope for sentinel lymph node biopsy in patients with breast cancer

The techniques for performing sentinel lymph node biopsy (SLNB) vary from institution to institution. Some advocate blue dye only, others radioisotope only, and many utilize a combination of both. The purpose of this study is to evaluate the additional benefit that blue dye provides when used in combination with a radioisotope. From October 2001 to June 2004, 102 SLNBs were attempted in 99 patients with breast cancer using a combination of blue dye and radioisotope. A lymph node was considered a sentinel lymph node (SLN) when it was stained with blue dye, had a blue lymphatic afferent, or had increased radioactivity. Ninety-eight patients had 101 successful identifications of SLNs, for an identification rate of 99%. Twenty-eight patients had positive SLNs. In three of those patients, although there were SLNs identified by both techniques, the positive SLNs were identified with only blue dye. Of the 102 SLNB procedures, there were two patients whose only SLN was identified by blue dye only. Although blue dye did not improve the identification rate, there was a definite benefit in improving the false-negative rate.     

美蓝和专利蓝在乳癌前哨淋巴结活检中作用的研究

目的 探讨美蓝及专利蓝两种蓝染剂鉴别前哨淋巴结（SLN）的成功率及预测乳癌淋巴结转移的准确性。方法 从1999年10月－2001年4月我科收治的乳癌病例中选取94例实施了前哨淋巴结活检（SNB）,其中于术中在乳腺肿块周围腺体内注射1％美蓝32例（美蓝组）、注射1％专利蓝62例（专利蓝组）、以鉴别定位SLN。全部病例都实施了腋淋巴结清扫术。结果 SLN鉴别的成功率美蓝组和专利蓝组分别为65．6％（21／32）和88．7％（55／62）（P＜0．01）;预测腋淋巴结转移状态准确性分别为90．5％（19／21）和98．2％（54／55）（P＞0．05）。结论 与美蓝比,专利蓝是较理想的乳癌SNB的生物活性染料示踪剂。
