  • Pathologic examination of sentinel lymph nodes in breast cancer by a single haematoxylin-eosin slide versus serial sectioning and immunocytokeratin staining: clinical implications
    Breast Cancer Research and Treatment, 2007
    Co-Authors: Reinou S. Groen, A. Wolter J. Oosterhuis, James E. Boers
    Abstract:

    Background The objective was to determine the additional value of pathologic examination using three-level sectioning and immunocytokeratin (ICK) staining of sentinel lymph node (SN) biopsies in cT1-2N0M0 breast carcinoma patients regarding lymph node staging and eligibility of systemic therapy taking primary tumor characteristics in account. Methods SN slides of 277 patients out of a total group of 961 patients known to have tumor-positive SNs detected by three-level sectioning and ICK staining were re-examined. Haematoxylin-eosin (HE) slide level three was scanned for tumor deposits, and when present, extra capsular extension, maximum tumor diameter and number of positive SNs was noted. In addition, slides of the axillary dissection of non-SNs were reviewed, with determination of metastasis size and number of positive non-SNs. Primary tumor characteristics (grade, diameter, estrogen receptor) were recorded. Results In the single-HE examination, 26 cases SN Micrometastasis and 6 macrometastasis were missed, 3 cases of Micrometastasis were incorrectly classified as isolated tumor cells, and 9 patients with macrometastasis were misclassified as Micrometastasis. In addition, in the tumor-negative single-HE examination, additional axillary lymph node dissection (ALND) revealed 6 cases of non-SN metastasis. Taking primary tumor factors into account for adjuvant systemic therapy, 21 patients would have been denied the choice for systemic therapy if single-HE examination was carried out only. Conclusions Single-HE examination of SN may result in a reduction of locoregional and systemic treatment according to treatment guidelines then current in the Netherlands.

  • Sentinel lymph node analysis in breast cancer: contribution of one-step nucleic acid amplification (OSNA)
    Breast Cancer Research and Treatment, 2012
    Co-Authors: Florence Godey, Jean Levêque, Patrick Tas, Gwenola Gandon, Philippe Poree, Habiba Mesbah, Vincent Lavoue, Véronique Quillien, Cécile Bendavid Athias
    Abstract:

    One-step nucleic acid amplification (OSNA, Sysmex, Kobe, Japan) offers an excellent opportunity for accurate exhaustive sentinel lymph node (SLN) examination in breast cancer patients. Calibrated with conventional postoperative histology, this molecular technique yields comparable results intraoperatively, expressed as Micrometastasis, macrometastasis or no metastasis depending on the CK19 mRNA copy number amplified in SLN lysates. We applied OSNA to detect metastasis in 810 SLNs from 367 patients with early stage breast cancer. We compared the rate of OSNA-positive SLNs in patients with invasive breast cancer (

  • Pure tubular carcinoma of the breast and sentinel lymph node biopsy: a retrospective multi-institutional study of 234 cases.
    EJSO - European Journal of Surgical Oncology, 2013
    Co-Authors: Magali Dejode, Gilles Houvenaeghel, Christine Sagan, Loïc Campion, Sylvia Giard, Jean-françois Rodier, Gwenael Ferron, Isabelle Jaffre, Jean Levêque, Cécile Bendavid
    Abstract:

    BACKGROUND: Pure Tubular Carcinoma (PTC) of the breast is a rare histological subtype of invasive breast cancer characterized by a low rate of lymph node involvement. Currently there is no consensus on less surgical axillary node staging according to this histological subtype. METHODS: We performed a retrospective multi-institutional study. Inclusion criteria were PTC, sentinel lymph node detection (SLND) and conservative breast surgery. RESULTS: From January 1999 to December 2006, 234 patients were included in the study from 9 institutions. The median pathological tumor size was 9.59 (1-22) mm. SLN were successfully detected in 98% (229/234) of patients. Among the 234 patients, a macrometastasis was found in 6 cases (2.5%), Micrometastasis in 15 cases (6.4%), and isolated cells in 2 cases (0.8%). In the case of patients with SLND macrometastasis, half of them had macrometastasis in the complementary axillary lymphadenectomy, and none in the case of SLN only Micrometastasis or isolated cells. Of the 122 patients with a pathological tumor size 10 mm) was the only parameter significatively linked to the risk of lymph node involvement (p = 0.007). CONCLUSION: In a large multi-institutional series with SLND, we have shown that the risk of axillary lymph node involvement in PTC is very low. In the case of PTC

  • abstract p1 01 21 sentinel lymph node detection after previous breast tumour surgical resection identification rate and false negative rate through a prospective multi institutional study

    Co-Authors: J M Classe, N Andrieux, C De Lara Tunon, H Charitansky, Fabrice Lecuru, Jl Houpeau, C Faure, P De Blaye, Gilles Houvenaeghel, D Kere
    Abstract:

    Background: Large multi institutional studies have pointed that previous surgical resection of breast tumours before axillary sentinel node detection (ASLND) was the main criteria of failure of this technique. Screening campaigns provide small tumours and despite efforts to obtain a diagnosis of early breast cancer, this is not always obtained, due to small tumours or false negative results of micro biopsies. The aim of our series was to assess identification rates and false negative rates of ASLND after previous surgical resection of breast tumours. Material and Methods: In a prospective multi institutional setting (14 multidisciplinary teams), we have included patients with a previous breast tumour surgical resection for the diagnosis of infiltrative breast adenocarcinoma. Patients with only a core biopsy and no surgical removal of the tumor before axillary surgery were not included. Each patient underwent a secondary surgical procedure for ASLND and axillary lymphadenectomy, and sometimes a breast secondary surgical procedure for margins. ASLND was performed with the combined method, with blue dye and technetium. Pathology was performed with serial sectioning, eosin safron and immune histo chemistry (IHC). Results: From July 2006 to November 2011, 138 patients where included. The median tumor size was 9mm. Identification rate was 86% (118/138). A macrometastasis was found in 11 cases, in a sentinel node (9), or in a non sentinel node(2). False negative rate was 9% (1 false negative sentinel node with macrometastasis in non sentinel node from lymphadenectomy/11 cases with a macrometastasis in either a sentinel node or a non sentinel node). In 1 case a Micrometastasis was found in a sentinel node through IHC, with a macrometastasis in a non sentinel node from lymphadenectomy. Without IHC or without the decision of performing a complementary lymphadenectomy in the case of Micrometastasis, the false negative rate would have been 18%. Conclusions: After previous surgical resection of early breast cancer, ASLND remains feasible with a low identification rate of 86%, despite the use of the combined method. The False negative rate is acceptable with the use of IHC. Citation Information: Cancer Res 2012;72(24 Suppl):Abstract nr P1-01-21.

  • A nomogram predictive of non-sentinel lymph node involvement in breast cancer patients with a sentinel lymph node Micrometastasis
    EJSO - European Journal of Surgical Oncology, 2009
    Co-Authors: Gilles Houvenaeghel, J M Classe, Sylvia Giard, Claude Nos, Hervé Mignotte, Benjamin Esterni, Jocelyne Jacquemier, Max Buttarelli, Monique Cohen, Philippe Rouanet
    Abstract:

    Purpose Predictive factors of non-sentinel lymph node (NSN) involvement at axillary lymph node dissection (ALND) have been studied in the case of sentinel node (SN) involvement, with validation of a nomogram. This nomogram is not accurate for SN Micrometastasis. The purpose of our study was to determine a nomogram for predicting the likelihood of NSN involvement in breast cancer patients with a SN Micrometastasis. Methods We collated 909 observations of SN micrometastases with additional ALND. Characteristics of the patients, tumours and SN were analysed. Results Involvement of SN was diagnosed 490 times (53.9%) with standard staining (HES) and 419 times solely on immunohistochemical analysis (IHC) (46.1%). NSN invasion was observed in 114 patients (12.5%), whereas 62.3% (71) had only one NSN involved and 37.7% (43) two or more NSN involved. In multivariate analysis, significant predictive factors were: tumour size (pT stage ≤10 mm or >11 and ≤20 or >20 mm [odds ratio (OR) 2.1 and 3.43], micrometastases detected by HES or IHC [OR 1.64], presence or absence of lymphovascular invasion (LVI) [OR 1.76], tumour histological type mixed or not [OR 2.64]. The rate and probability of NSN involvement with the model are given for 24 groups, with a representation by a nomogram. Conclusion One group, corresponding to 10.1% of the patients, was associated with a risk of NSN involvement of less than 5%, and five groups, corresponding to 29.8% of the patients, were associated with a risk ≤10%. Omission of ALND could be proposed with minimal risk for a low probability of NSN involvement.
