Single-port Non-liposuction Endoscopic Axillary Lymph Node Dissection in Breast Cancer Surgery
0 Views •
2026
This study describes a standardized surgical procedure for single-port endoscopic axillary lymph node dissection without liposuction in breast cancer. Indicated for patients with biopsy-confirmed nodal metastasis or positive sentinel lymph nodes, the technique emphasizes preservation of critical structures, particularly the intercostobrachial nerve, to reduce postoperative morbidity and optimize functional recovery.

Source: Richard Glickman-Simon, MD, Assistant Professor, Department of Public Health and Community Medicine, Tufts University School of Medicine, MA The lymphatic system has two main functions: to return extracellular fluid back to the venous circulation and to expose antigenic substances to the immune system. As the collected fluid passes through lymphatic channels on its way back to the systemic circulation, it encounters multiple nodes consisting of highly concentrated clusters of...

Two-photon imaging has uncovered lymphocyte motility and cellular interactions within the lymph node under basal conditions and durring an immune response 1. Here, we demonstrate adoptive transfer of T cells, isolation of lymph nodes, and imaging motility of CD4+ T cells in the explanted lymph node.

This protocol describes the application of high-frequency ultrasound (HFUS) for imaging mouse cervical lymph nodes. This technique optimizes visualization and quantification of cervical lymph node morphology, volume and blood flow. Image-guided biopsy of cervical lymph nodes and processing of lymph tissue for histological evaluation is also demonstrated.

FAQs
The sentinel node is the first lymph node to receive drainage from a tumor. Examining it can provide evidence about whether malignant cells have moved from the primary tumor into regional lymphatic tissue. This makes sentinel-node selection useful for connecting local tumor behavior with lymphatic spread and for supporting cancer staging.
Microscopic examination determines whether the sampled tissue contains malignant cells. Those findings help characterize the extent of disease beyond the primary tumor, contributing to staging and prognosis. In turn, clinicians can use the pathology result to support treatment planning when assessing whether regional lymphatic involvement is present.
The collected tissue can support molecular analyses of tumor biology, extending evaluation beyond the microscopic presence or absence of malignant cells. Researchers can use these analyses to investigate characteristics of the tumor and its therapeutic response. This creates a link between diagnostic sampling and studies of how cancer behaves or responds to treatment.
Sampling may involve an imaging-guided needle or removal of a selected lymph node. Imaging can help guide the needle toward the intended tissue, while selected-node removal provides a specimen for pathological examination. The approach therefore determines how the relevant axillary tissue is obtained before microscopic and, when appropriate, molecular assessment.
It is relevant when investigators or clinicians need information about possible spread through regional lymphatic tissue. The resulting findings can contribute to staging, prognosis, and treatment planning. In research, the same specimens may also provide material for examining tumor biology and therapeutic response, making the procedure useful for both disease assessment and scientific investigation.
Results provide evidence about whether malignant cells are present in lymphatic tissue associated with the primary tumor. That evidence helps indicate the extent of disease, which contributes to staging and prognosis. Because treatment planning depends partly on disease extent, the pathology findings can help guide decisions about the broader cancer management approach.
