BACKGROUND: There were limited data available for a head-to-head comparison of the identification rate and survival between the combined method of indocyanine green fluorescence and blue dye versus the traditional blue dye alone method for sentinel lymph node (SLN) biopsy. METHODS: From January 2013 to December 2015, 523 eligible breast cancer patients were included in this nonrandomized prospective analysis. The identification rates, the number of SLNs identified, and the disease-free survival (DFS) between the two mapping methods were compared...

BACKGROUND: In patients undergoing breast-conserving surgery and having positive sentinel lymph nodes (SLNs), the ACOSOG Z0011 trial showed equivalent loco-regional outcomes for patients receiving SLN dissection (SLND) alone and those receiving axillary lymph node dissection (ALND). We conducted a prospective single-arm study to confirm the applicability of the Z0011 criteria to Japanese patients with breast cancer. METHODS: Patients meeting the Z0011 inclusion criteria and providing consent to receive no additional ALND were prospectively enrolled at the Osaka International Cancer Institute from April 2012 to December 2016...

The main objective of the ACOSOG Z0011 trial was to determine the impact of abandoning complete axillary lymph node dissection (ALND) on survival of breast cancer patients with sentinel node lymph (SLN) metastasis in whom breast conserving therapy (BCT) had been performed. The aim of our study was to assess the clinical value of intra-operative histopathological examination of SLN. Our study comprised 1284 invasive breast cancer patients in whom sentinel lymph node biopsy (SLNB) was carried out. SLN intra-operative histopathological assessment was routinely performed in patients treated within the first period (07...

There is no previous predictive model to assess risk of nonsentinel lymph node metastases (NSLN) in sentinel lymph node (SLN)-positive breast cancer patients after neoadjuvant chemotherapy (NAT). Our goal was to develop a new predictive model for SLN-positive patients after NAT, and validate this new model. A series of 513 patients with metastases in SLN who received NAT were used to evaluate factors affecting NSLN status. Logistic regression analysis was performed to develop a predictive model, which was validated by a subsequent prospective 138 patients...

Currently, the use of radioisotope and blue dye for sentinel lymph node biopsy (SLNB) for axillary staging in breast cancer is common. Recently, indocyanine green (ICG) has been proposed as an alternative sentinel lymph node (SLN) tracking agent. We evaluated the clinical value of ICG as an additional tracer in combination with Technetium99m and as an alternative to Technetium99m for the identification of SLN in 104 breast cancer patients. 21 patients had at least 1 histologically tumor-positive SLN. All 21 patients were detected by ICG; in one of these 21 sentinel-positive patients, Technetium99m was unable to identify lymph node involvement...

OBJECTIVES: In case of large breast cancer, neoadjuvant chemotherapy (NAC) can be performed to reduce the size of the tumor and thus perform a conservative surgery. The place of the sentinel lymph node biopsy (SLNB) in case of NAC is still debated. The main aim of this study is to assess the risk of axillary recurrence after negative SLNB before NAC. METHODS: It is a retrospective, observational and uni-centric study. We included 18 to 80-year-old patients with unilateral breast cancer requiring a NAC and with a negative SLNB before NAC...

Background: Metaplastic breast cancer (MBC), characterized by admixed epithelial, squamous or mesenchymal elements, constitutes <1% of breast cancers and has a poor prognosis but a paradoxically low reported rate of axillary lymph node (LN) involvement. Due to its rarity, data on appropriate axillary management is lacking, prompting this investigation of LN status and outcomes. Methods: We identified 41 MBC patients treated at our institution 2001-2011 who were followed for a median of 66 months...

Technetium (99mTc)-radiolabeled colloids are popular tracers used to map lymphatic vessels and regional lymph nodes (LNs). The regional LN status is a significant determinant of cancer stage and patient prognosis, and strongly influences treatment. Regional LN dissection has become part of surgical treatment. However, not all patients with LN involvement benefit from extensive lymphadenectomy in terms of prolonged survival. Moreover, overtreatment of patients with localized disease carries unnecessary risk of complications...

One-step nucleic acid amplification (OSNA) is an established method for intraoperative diagnosis of breast cancer metastasis in sentinel lymph nodes, based on quantification of CK19 mRNA, specific to breast epithelial cells. Inhibitors interfere with the PCR amplification process of PCR. Thus, OSNA, based on gene amplification without RNA purification, might be impacted by numerous factors persisting in a sample, and thereby potentially acting as PCR inhibitors. However, neither the characteristics of breast cancers showing inhibitory effects during OSNA, nor any of the possible inhibitors, have as yet been identified...

The level of axillary lymph node involvement in breast cancer is a critical decision factor for adjuvant therapy and the most important indicator of prognosis and survival. Sentinel lymph node biopsy is a minimally invasive technique with low morbidity in axillary staging of breast cancer. Radiocolloid substances (Technetium-99m) and/or blue dyes such as methylene blue or isosulfan blue are used during sentinel lymph node biopsy. Isosulfan blue stain is frequently used in sentinel lymph node biopsy and rarely causes complications...

Patent blue is one of the most used dyes for the identification of sentinel lymph nodes in breast cancer. This report describes a case of an anaphylactic shock reaction to patent blue dye in a patient with cross-reactivity to methylene blue. Therefore, after allergy confirmation, the operation was repeated avoiding blue dye and an alternative labelling technique with 99mTc albumin nanocolloids was used.
