Axillary lymph node status remains an important prognostic factor in early breast cancer. It is regarded as an indicator for (neo)adjuvant systemic treatment and postoperative radiotherapy of the regional lymphatics. Commenced in September 2015, the INSEMA trial is investigating whether operative determination of nodal status as part of breast conserving therapy (BCT) for early stage breast can...
International guidelines reveal substantial differences regarding indications for regional nodal irradiation (RNI). Recently, several randomized studies provided new insights and these are discussed here. Patients with 1-3 positive nodes seem to profit from RNI compared to whole-breast (WBI) or chest-wall irradiation (CWI) alone, both with regard to locoregional control and disease-free surviva...
A case of single breast metastasis from colon adenocarcinoma, with omolateral axillary micrometastasis, is reported with a brief review of the pertinent literature. The originality of the oncological concept of metastasis from metastasis, through lymphatics penetration, is discussed in the setting of a rare condition of breast metastasis from a colorectal carcinoma. The demonstration of axillar...
BACKGROUND: Axillary node dissection is considered a standard staging procedure in patients with breast cancer. The procedure is associated with significant morbidity and provides pathologists with many lymph nodes to evaluate. METHODS: A total of 174 women participated in a trial that included preoperative lymphoscintigraphy and intraoperative lymphatic mapping using a combination of a vital b...
Massive campaigns of screening of breast pathologies improved early diagnosis of breast cancers. Most of these cancers are small-sized (T1) and seldom show intraoperative nodal involvement. Sentinel node biopsy is the elective choice in the above mentioned cases because, if negative, it avoids axillary dissection. International literature reports rates of false negative sentinel node biopsy ran...
BACKGROUND The main prognostic factor in early staged breast cancer is the axillary lymph node metastatic affection. Sentinel lymph node biopsy, as a staging modality, significantly decreases surgical morbidity. The status of internal mammary lymph nodes gains an increased predictive role in grading breast carcinomas and modulation of postoperative therapeutic protocols. If positive, almost alw...
Background and Aim: Sentinel lymph node (SLN) biopsy is a useful way of assessing axillary nodal status and obviating the need for axillary lymph node dissection (ALND) in patients with breast cancer. The aim of this study was to assess the accuracy of the SLN biopsy in the correct prediction of ALN involvement. Materials and Methods: Thirty three patients with breast cancer that had been opera...
BACKGROUND Recently, the American College of Surgeons Oncology Group Z0011 trial demonstrated that axillary lymph node dissection (ALND) could be safely avoided in selected breast cancer patients with limited nodal disease and having breast conservation therapy. However, for node positive (N+) mastectomy patients, full ALND remains the standard of care. Hypothesizing that omission of complete A...
BACKGROUND The aim of the present study was to investigate the long-term impact of prognostic factors in invasive lobular carcinoma (ILC) of the breast, with a primary focus on Ki67 and histological grade, alone and in combination with estrogen receptor (ER). MATERIAL AND METHODS One hundred and ninety two well-characterised patients with ILC were included in the study. Ki67, histological gra...
Histologic assessment is the gold standard technique for the identification of metastatic involvement of lymph nodes in malignant disease, but can only be performed ex vivo and often results in the unnecessary excision of healthy lymph nodes, leading to complications such as lymphedema. Optical coherence tomography (OCT) is a high-resolution, near-IR imaging modality capable of visualizing micr...
