New Online Tool Calculates Risk of Non-sentinel Lymph Node Metastasis
Kohrt HE, Olshen RA, Bermas HR, et al. New models and online calculator for predicting non-sentinel lymph node status in sentinel lymph node positive breast cancer patients. BMC Cancer. 2008 Mar 4;8:66. PMID: 18315887
A multidisciplinary team at Stanford University Medical Center and other Bay Area institutions have developed a new online calculator for determining risk of non-sentinel lymph node metastasis in breast cancer patients with sentinel lymph node metastasis.
The online calculator is intended for patients who have received a sentinel lymph node biopsy without evidence of obvious non-sentinel lymph node metastasis on physical examination. Three tumor characteristics are required: size of tumor, size of sentinel lymph node metastasis, and presence or absence of angiolymphatic invasion status.
From the statement of purpose:"Knowing the chance of non-sentinel lymph node metastasis allows clinicians and their patients to balance the benefits and risks of additional axillary lymph node surgery for individualized care."
