Isolated retromammary lymph node metastasis of breast cancer without axillary lymph node involvement: a case report with a false-negative sentinel lymph node biopsy

A 54-year-old woman visited our hospital with a palpable tumor in her left breast, which was diagnosed as invasive ductal carcinoma. Breast-conserving surgery was performed, in association with a sentinel lymph node (SLN) biopsy and back-up dissection of the axillary lymph nodes. One dyed axillary lymph node with high radioactivity was defined as an SLN, and intraoperative frozen-section analysis of the SLN was negative for metastasis. The final pathological diagnosis of the tumor was invasive ductal carcinoma, and one small lymph node, located in the retromammary space, just under the tumor, was positive for metastasis. The backup axillary lymph nodes were not metastatic. This patient was diagnosed false-negative by SLN biopsy, despite being positive for retroMLN metastasis. It should be recognized that retroMLNs are difficult to detect preoperatively, or intra-operatively, using dye or radiocolloid, if they are located in the post-tumoral retro-mammary space. RetroMLNs may be a pitfall in SLN biopsies.

Validation of axillary sentinel lymph node detection in the staging of early lobular invasive breast carcinoma: a prospective study

BACKGROUND: Previous reports have shown that regional lymph node involvement in patients with early-stage breast carcinoma can be evaluated by resection of axillary sentinel lymph nodes (ASLN). Axillary lymphadenectomy may be unnecessary in the absence of ASLN involvement. In the current study, the authors compared the results of ASLN resection in patients with lobular invasive carcinoma (LIC) with the results from patients with ductal invasive carcinoma (DIC) in terms of detection rates and false-negative rates. METHODS: For ASLN detection, technetium 99m sulfur-colloid and patent blue were injected around the tumor. Each patient underwent both ASLN resection and complete axillary lymphadenectomy. Detection rates and false-negative rates were evaluated in patients with LIC and in patients with DIC. RESULTS: Two hundred forty-three patients with invasive, early-stage breast carcinoma were enrolled in the study (208 patients with DIC and 35 patients with LIC). The median patient age, pathologic tumor size, hormone receptor status, and rates of involved lymph nodes were equivalent for both groups. ASLN detection and false-negative rates did not differ for patients with LIC and patients with DIC. CONCLUSIONS: The ASLN detection rate was not dependent on the pathologic type of invasive carcinoma. Pathologic examination of ASLN in patients with LIC and in patients with DIC predicted axillary lymph node status with the same predictive value in terms of lymph node metastasis. For patients with LIC, ASLN examination overestimated the rate of micrometastasis as diagnosed by immunohistochemical techniques. These results will require confirmation in larger studies.     

Spontaneous apoptosis in the intra-ductal component's stroma of breast invasive carcinoma

Spontaneous apoptosis by in situ detection of DNA fragmentation (DNAf) was investigated in breast invasive ductal carcinoma (IDC) frozen samples removed from 61 untreated patients. The incidence of DNAf was low in carcinoma cells and was mainly detected in the stroma. In the stroma at a distance from carcinoma cells, DNAf was inversely related to estradiol plasma level variations (p=0.01), indicating that it probably remained under physiological hormonal regulation. In the stroma adjacent to carcinoma cells, DNAf was correlated to tumor progression parameters such as the presence of a comedo intra ductal carcinoma (DCIS) component (p=0.001) and axillary lymph node metastasis (p=0.002), suggesting that this stromal compartment more probably represented a tumoral component closely associated to epithelial tumor cells. Therefore, the detection of DNAf in the adjacent stroma of breast carcinoma could help to predict progression in non invasive tumors and also in invasive tumors in those patients without lymph node invasion.     

Contralateral uptake and metastases in sentinel lymph node mapping for recurrent breast cancer

BACKGROUND AND OBJECTIVES: Sentinel lymph node mapping as a constitutive component in the staging process for invasive breast cancer continues to gain acceptance. We have identified two patients with recurrent invasive breast cancer in whom contralateral sentinel lymph node uptake and metastases, respectively, were detected. Such findings have not been previously reported in our review of the medical literature between 1966 and October 2004. METHODS: Sentinel lymph node mapping was performed on two patients with recurrent invasive breast cancer at our institution. At the time of their index diagnosis, both had received breast conserving surgery and an axillary lymph node dissection with post-operative radiotherapy (RT). All lymph nodes and margins of resection were without tumor. Both patients remained with no evidence of disease for years until routine serial screening mammography was interpreted as suspicious. Each underwent a stereotactic biopsy of the ipsilateral breast corresponding to the mammographic abnormality. Pathology confirmed invasive ductal carcinoma. Both patients refused the recommended salvage mastectomy. PRINCIPAL RESULTS: During a second attempt at breast conservation, sentinel lymph node mapping--which is typically contraindicated for patients with prior axillary surgery--revealed contralateral axillary uptake for both patients. The respective contralateral sentinel node was excised with pathology revealing no tumor in one case, and a microscopic focus of metastatic carcinoma in the second case. MAJOR CONCLUSION: Some patients may benefit from sentinel lymph node mapping prior to salvage mastectomy. Identifying uptake in a contralateral sentinel lymph node may change the multi-disciplinary management of recurrent invasive breast cancer to include a contralateral axillary dissection, chemotherapy, and/or RT to the contralateral axilla.     

乳腺导管原位癌伴微浸润发生腋窝淋巴结转移的相关因素分析

目的探讨乳腺导管原位癌伴微浸润(breast ductal carcinoma in situ withmicroinvasion,DCIS-Mi)患者发生腋窝淋巴结转移的危险因素。方法应用回顾性调查方法收集2000年1月至2008年10月可手术乳腺DCIS-Mi病例共174例,分析有无腋窝淋巴结转移患者的不同分子病理特征,并通过χ2检验、Spearman检验以及Logistic回归分析筛选腋窝淋巴结转移的危险因素。结果 174例DCIS-Mi患者中,有腋窝淋巴结转移者9例(5.17%)。DCIS-Mi病灶中,DCIS级别与腋窝淋巴结转移呈正相关(r=0.262,P=0.000),激素受体状态与腋窝淋巴结转移呈负相关(r=-0.192,P=0.011)。经Logistic回归分析各因素相互调整后,DCIS高级别(OR=37.191,P=0.005)和肿瘤直径≥4.0cm(OR=29.634,P=0.023)是DCIS-Mi病灶发生转移的高危因素。结论在DCIS-Mi患者中,DCIS级别高和肿瘤直径≥4.0cm者容易发生腋窝淋巴结转移,对此类患者进行个体化治疗是必要的。     

Lymph node metastases versus DNA ploidy as prognostic factors for invasive ductal carcinoma of the breast

We evaluated the relationship between the DNA ploidy status and other variable prognostic factors, especially regional lymph node metastases, in 121 patients with invasive ductal carcinoma of breast, together with the value of these factors in estimating the prognostic of breast cancer. The ploidy status was diploid in 40% of the patients, and aneuploid in 60%. A significantly higher incidence of aneuploidy was found in patients with more than 4 positive axillary lymph nodes, positive internal mammary lymph nodes, or clinical stage 3 of malignancy. In a univariate study, overall survival and disease-free survival were significantly correlated with axillary and internal mammary lymph node metastases, tumor size, and clinical stage of malignancy. The disease-free survival rates for the diploid group tended to be somewhat higher than those for the aneuploid group of patients without axillary lymph node metastases. In the multivariate analysis, however, only axillary lymph node metastasis was significantly correlated with overall survival and disease-free survival. There was also a trend for the internal mammary lymph node metastases to be correlated with survival. As the DNA ploidy status was closely correlated with the axillary and internal mammary lymph node metastases, it did not appear to be an independent prognostic factor in this small series.     

A case of HER-2-positive advanced inflammatory breast cancer with invasive micropapillary component showing a clinically complete response to concurrent trastuzumab and paclitaxel treatment

We report a case of HER-2-positive advanced inflammatory breast cancer with invasive micropapillary component showing a complete response to trastuzumab and paclitaxel treatment. A 37-year-old woman was referred to our hospital for right breast swelling with broad skin redness and right axillary tumor. Ipsilateral infraclavicular and contralateral axillary lymph nodes swelling were also recognized. The histopathological findings of core-needle biopsy specimens from primary breast tumor and ipsilateral axillary lymph node were invasive ductal carcinoma with a micropapillary component. Immunohistochemical examination gave a negative result for estrogen receptor (ER)/progesterone receptor (PgR), and overexpression of HER-2 (Hercep Test 3+). Advanced inflammatory breast cancer with an invasive micropapillary component was diagnosed (T4d N3 M1 (LYM), stage IV). The patient was treated with combination chemotherapy using weekly paclitaxel and trastuzumab. After administration of three courses, the breast swelling, skin redness, and lymph node swelling disappeared completely. She maintained complete remission of disease for 12 months and was judged to have a clinically complete response by the RECIST criteria. Invasive micropapillary carcinoma is known to be an aggressive histological type associated with a high incidence of lymph node metastasis and poor prognosis. This is the first reported case of advanced inflammatory breast cancer with an invasive micropapillary component showing a clinically complete response to trastuzumab-containing treatment. This report suggests trastuzumab-containing chemotherapy is a promising therapy for HER-2-positive advanced invasive micropapillary carcinoma.
