In each quadrant, a breast cancer may drain to sentinel nodes in various locations. There is a distinct difference in drainage patterns between palpable and nonpalpable lesions. These findings may improve the assessment of lymphatic dissemination in invasive breast cancer.
Extremity myxoid liposarcomas have an unusually high predilection for extra-pulmonary metastases, frequently without any pulmonary metastases. After treatment of the primary tumor, these patients should be followed with periodic chest X-ray and abdominal/pelvic computed tomography (CT) scans. Any back or neurologic complaints should prompt additional imaging of the appropriate spinal area. Consideration should be given to surgical and adjuvant treatment of metastatic disease when appropriate.
Pursuit of IMC sentinel nodes improves the staging of patients with breast cancer and enables treatment to be better adjusted to the needs of the individual patient.
This study confirms that the status of the sentinel node is a strong independent prognostic factor. The false-negative rate and the incidence of in-transit metastases in sentinel node-positive patients are high and have to be weighed against the possible survival benefit of early removal of nodal metastases.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
