背景与目的:大部分前哨淋巴结(sentinel lymph node,SLN)阳性而接受腋窝淋巴结清扫术(axillary lymph node dissection,ALND)的患者,腋窝非前哨淋巴结(non-sentinel lymph node,nSLN)并没有发生转移,因此准确预测nSLN转移至关重要.该研究将建立基于分子诊断一步核酸扩增法(one-step nucleic acid amplification,OSNA)的术中快速预测乳腺癌nSLN转移的模型,以期有效指导乳腺癌后续治疗.方法:利用2010年OSNA临床试验入组的552例患者中SLN阳性、并接受ALND的103例患者数据,建立基于分子诊断的乳腺癌NSLN转移的预测模型,并利用2015年OSNA临床试验入组的327例患者中61例符合相同条件的患者数据进行验证.结果:原发肿瘤大小、SLN总肿瘤负荷、SLN阳性数及阴性数是NSLN转移的四个独立相关因素,利用这四个因素建立预测列线图,得出建模组患者的受试者工作特征(receiver operating characteristic curve,ROC)曲线的曲线下面积(area under the ROC curve,AUC)为0.814,验证组患者的AUC为0.842.利用验证组61例患者影像学评估的肿瘤大小替代病理大小对本模型进行了验证,得出AUC为0.838,与模型验证性AUC相比差异无统计学意义(P=0.7406).结论:基于分子诊断的乳腺癌预测nSLN转移的模型既可以术中快速预测腋窝淋巴结转移风险,也可以术后常规预测,明显优于其他预测模型,对后续腋窝的处理及放疗靶区勾画具有更好的指导价值.  相似文献

乳腺癌前哨淋巴结活检术中分子诊断的研究进展   总被引:1,自引:0,他引:1  
乳腺癌前哨淋巴结(sentinel lymph node,SLN)能准确反映腋窝淋巴结的状况。前哨淋巴结活检术(sentinel lymph node biopsy,SLNB)已成为临床腋窝淋巴结阴性早期乳腺癌患者的标准腋窝处理模式。准确、快速、客观的SLN术中诊断可以使SLN阳性患者通过一次手术完成腋窝淋巴结清除,避免二次手术带来的风险及并发症,为患者和术者节约了时间,降低了手术风险,并减少了二次手术带来的费用负担。近年来,术中分子诊断已成为乳腺癌SLN研究的热点之一。  相似文献

Objective To assess whether the Memorial Sloan Kettering Cancer Center (MSKCC) nomogram for prediction of NSLN metastasis is useful in a German breast cancer population and whether the characteristics of the breast tumor and the sentinel lymph node (SLN) are able to predict the likelihood of non-sentinel lymph node (NSLN) metastasis. Methods A total of 545 patients with primary breast cancer and SLN examination were evaluated. The MSKCC nomogram was applied to 98 patients with a positive SLN who subsequently had completion axillary lymph node dissection (ALND). Predictive accuracy was assessed by calculating the area under the receiver-operator characteristic (ROC) curve. The collective was evaluated by correlating the prevalence of NSLN and SLN metastasis to pathological features. Results The MSKCC nomogram achieved a ROC of 0.58 indicating a bad accuracy of the nomogram. Tumor size, histology, lymphovascular infiltration, multifocality, Her-2-neu positivity, and nuclear grade correlated with the probability of SLN metastasis. Histology and primary tumor localization correlated significantly with the probability of NSLN metastasis. Conclusions The MSKCC nomogram did not provide a reliable predictive model in our study population. However, the likelihood of SLN metastasis correlated with the presumed risk factors and no obvious differences between the MSKCC population and our population could be seen. In order to achieve interinstitutional reproducibility, standardization of surgical procedure and of the pathological assessment of the SLN is desirable.  相似文献

BACKGROUND:

Several models for the prediction of nonsentinel lymph node (NSLN) metastasis in sentinel lymph node (SLN)‐positive breast cancer patients have been proposed. In this study, the authors evaluate the Stanford Online Calculator (SOC), which was designed to predict the likelihood of NSLN metastasis using only 3 variables: primary tumor size, SLN metastasis size, and angiolymphatic invasion status. They compared it with the Mayo and Memorial Sloan‐Kettering Cancer Center (MSKCC) nomograms.

METHODS:

The SOC was used to calculate the probability of NSLN metastasis in 464 breast cancer patients with SLN metastasis who underwent completion axillary lymph node dissection at the Mayo Clinic. The area under the receiver operating characteristic curve (AUC) was calculated for each model. Mean probabilities of patients with and without NSLN metastasis were compared. Patients with ≤5%, ≤10%, and 100% NSLN metastasis probabilities were examined.

RESULTS:

The AUCs of the Stanford, MSKCC, and Mayo models were 0.72, 0.74, and 0.77, respectively (P = .13). The mean Stanford probabilities for patients with and without NSLN metastasis were 0.75 (range, 0.06‐1.0) and 0.50 (range, 0.05‐1.0), respectively (P < .0001). The false‐negative rates for patients with a Stanford probability of ≤5% and ≤10% were 0% and 13%, respectively. Of the patients with a Stanford probability of 100%, 26% did not have NSLN metastasis.

CONCLUSIONS:

Despite using only 3 variables, the Stanford nomogram appears to perform on a par with, but not better than, the MSKCC and Mayo nomograms. Further validation in other patient populations is needed. Cancer 2009. © 2009 American Cancer Society.  相似文献

Background: The aim of the study was to evaluate the available breast nomograms (MSKCC, Stanford, Tenon)to predict non-sentinel lymph node metastasis (NSLNM) and to determine variables for NSLNM in SLN positivebreast cancer patients in our population. Materials and Methods: We retrospectively reviewed 170 patientswho underwent completion axillary lymph node dissection between Jul 2008 and Aug 2010 in our hospital. Wevalidated three nomograms (MSKCC, Stanford, Tenon). The likelihood of having positive NSLNM based onvarious factors was evaluated by use of univariate analysis. Stepwise multivariate analysis was applied to estimatea predictive model for NSLNM. Four factors were found to contribute significantly to the logistic regressionmodel, allowing design of a new formula to predict non-sentinel lymph node metastasis. The AUCs of the ROCswere used to describe the performance of the diagnostic value of MSKCC, Stanford, Tenon nomograms and ournew nomogram. Results: After stepwise multiple logistic regression analysis, multifocality, proportion of positiveSLN to total SLN, LVI, SLN extracapsular extention were found to be statistically significant. AUC results wereMSKCC: 0.713/Tenon: 0.671/Stanford: 0.534/DEU: 0.814. Conclusions: The MSKCC nomogram proved to bea good discriminator of NSLN metastasis in SLN positive BC patients for our population. Stanford and Tenonnomograms were not as predictive of NSLN metastasis. Our newly created formula was the best predictiontool for discriminate of NSLN metastasis in SLN positive BC patients for our population. We recommend thatnomograms be validated before use in specific populations, and more than one validated nomogram may beused together while consulting patients.  相似文献

BACKGROUND AND OBJECTIVES: In order to predict the nonsentinel lymph node (NSLN) metastases in sentinel lymph node (SLN) positive patients a nomogram was created at the Memorial Sloan Kettering Cancer Centre (MSKCC). The aim of our study was to validate the MSKCC nomogram in patients grouped by the preoperative ultrasound (US) examination of the axillary lymph nodes. METHODS: The MSKCC nomogram was validated separately in three groups of patients: (US-0) only clinically preoperatively negative axillary lymph nodes (126 patients), (US-1) US negative axillary lymph nodes (109 patients), and (US-2) US suspicious but fine needle aspiration biopsy (FNAB) negative axillary lymph nodes (41 patients). RESULTS: The predicted probability underestimates the actual probability with the mean absolute error equal to 0.116 in the US-0 group (P = 0.003), and overestimates the actual probability (mean absolute error equal to 0.084) in US-1 group (P = 0.033) and US-2 group (mean absolute error is 0.110) (P = 0.275). CONCLUSION: We found that the MSKCC nomogram overestimates the probability of the NSLN metastases in breast cancer patients with (i) preoperatively US negative or (ii) US suspicious, but FNAB negative axillary lymph nodes. We also found that MSKCC nomogram has only limited value in patients with only clinically negative axillary lymph nodes.  相似文献

Several models have previously been proposed to predict the probability of non-sentinel lymph node (NSLN) metastases after a positive sentinel lymph node (SLN) biopsy in breast cancer. The aim of this study was to assess the accuracy of two previously published nomograms (MSKCC, Stanford) and to develop an alternative model with the best predictive accuracy in a Czech population. In the basic population of 330 SLN-positive patients from the Czech Republic, the accuracy of the MSKCC and the Stanford nomograms was tested by the area under the receiver operating characteristics curve (AUC). A new model (MOU nomogram) was proposed according to the results of multivariate analysis of relevant clinicopathologic variables. The new model was validated in an independent test population from Hungary (383 patients). In the basic population, six of 27 patients with isolated tumor cells (ITC) in the SLN harbored additional NSLN metastases. The AUCs of the MSKCC and Stanford nomograms were 0.68 and 0.66, respectively; for the MOU nomogram it reached 0.76. In the test population, the AUC of the MOU nomogram was similar to that of the basic population (0.74). The presence of only ITC in SLN does not preclude further nodal involvement. Additional variables are beneficial when considering the probability of NSLN metastases. In the basic population, the previously published nomograms (MSKCC and Stanford) showed only limited accuracy. The developed MOU nomogram proved more suitable for the basic population, such as for another independent population from a mid-European country.  相似文献
