The risk of metastasis to further echelon nodes is higher with macrometastases, especially if there is extracapsular growth and the proportion of involved sentinel nodes is high.īreast cancer, metastasis, multivariate analysis, non-sentinel lymph nodes, sentinel lymph nodes INTRODUCTION Results: The following variables were found to be potentially associated with non-sentinel node metastases: tumour size, sentinel node metastasis size, number of examined sentinel nodes, percentage of involved sentinel nodes (the latter two were found to be significant only when in combination), and extracapsular perinodal spread.Ĭonclusions: Isolated tumour cells and micrometastases in axillary sentinel nodes carry a low risk of non-sentinel node metastasis.

#Sentinel node series#

For a series of 150 consecutive patients with involved axillary sentinel nodes and axillary dissection, factors associated with non-sentinel nodal involvement were analysed in a multivariate analysis based on logistic regression with the use of fractional polynomials. Methods: Sentinel node biopsy was performed either with Patent blue dye or with a combined dye, radiocolloid and gamma-probe-guided method involving peritumoral tracer administration. These patients are exposed to the morbidity of axillary clearance without any expected therapeutic benefit.

To learn more about sentinel node mapping and biopsy, breast cancer surgery or other procedures, call 1-88 or use our convenient online new patient registration form to schedule an appointment.Background: After completion of axillary dissection, many breast cancer patients with axillary sentinel nodal involvement are found to have regional disease limited to the sentinel nodes. This is just one way we ensure the best possible patient care.

At Moffitt, every patient’s case is thoroughly reviewed and monitored by a talented team of specialists in a wide range of disciplines. The Don & Erika Wallace Comprehensive Breast Program features a full-service clinic that offers comprehensive and highly individualized plans that incorporate cancer prevention, diagnosis, treatment and support. Patients who are seeking the latest breast cancer diagnostic and treatment options are welcome to come to Moffitt Cancer Center – with or without referrals. If cancerous cells are not found in the sentinel node, lymph node involvement is unlikely, but if the sentinel node tests positive, further evaluation or treatment is usually recommended. A pathologist examines the sentinel node under a microscope for evidence of cancer.The surgeon identifies the sentinel node by observing which node absorbs the tracer first.During surgery, a surgeon injects a “tracer” substance, such as a blue dye, into the affected breast near the tumor.A sentinel node mapping and biopsy typically involves the following steps: On the other hand, if lymph node involvement is confirmed before surgery, a patient may be advised to undergo axillary lymph node dissection, which is a more complex procedure designed to remove the cancer-containing lymph nodes. When lymph node involvement is unconfirmed prior to surgery, sentinel node mapping and biopsy may be recommended as a less invasive alternative to axillary dissection for obtaining information about how far a patient’s breast cancer has spread. The axillary lymph node located closest to the breast cancer tumor is known as the “sentinel node.”īecause this lymph node handles drainage from the breast, it is usually the first area where breast cancer cells metastasize. The information gleaned from this procedure can be utilized by oncologists when staging the cancer and planning the patient’s follow-up treatment. Sentinel node mapping and biopsy is a technique that may be performed in conjunction with breast cancer surgery, such as a mastectomy, in order to assess the lymph nodes in the underarm area (axillary lymph nodes) for evidence of cancer.
