Jump to navigation. This review aimed to compare the benefits of surgical removal of underarm lymph nodes with the potential harms associated with this surgical procedure. The review also aimed to learn whether complete removal of all underarm nodes could be replaced by procedures that remove only a small number of lymph nodes.

Complete lymph node removal through conventional axillary dissection ALND has been standard treatment for breast cancer patients for almost a century. In the s, however, and in parallel with the advent of the sentinel lymph node SLN procedure, ALND came under increasing scrutiny due to its association with significant patient morbidity. Several studies have since provided evidence to suggest omission of ALND, often in favor of axillary radiation, in selected clinically node-negative, SLN-positive patients, thus supporting the current trend in clinical practice.
Surgeon volume was reported as the number of new patients with a breast cancer diagnosis seen in the past 12 months after adjustment for sex, years in practice, and site. Propensity for ALND was described as low, selective, and high. Acceptance of a margin of no ink on tumor was assessed using the scenario of a year-old woman with a clinical T1bN0, estrogen receptor—positive, progesterone receptor—positive, HER2 -negative cancer having lumpectomy with planned whole-breast irradiation.
If a clinical breast exam identifies a breast lump, calcifications that look suspicious are seen on a mammogram, or an ultrasound or MRI identifies an area that looks abnormal, typically the next step is a biopsy. A biopsy is a sample of cells or tissue. The biopsy is sent to a cytologist or pathologist who will look at it closely under a microscope and may also perform tests on the cells to learn more about them.

A lthough the involvement of axillary nodes remains a significant prognostic factor used in the management of breast cancer, the management of the axilla has changed dramatically. Among women with clinically negative nodes, the National Surgical Adjuvant Breast and Bowel Project NSABP B trial showed no difference in survival among those treated with radical mastectomy including axillary clearancesimple mastectomy plus radiation without axillary surgery, or simple mastectomy alone. The use of SLNB led to more detailed pathologic examination of the sentinel node to identify limited or micrometastatic nodal involvement that previously went undetected. Given the absence of a survival advantage associated with AND, many oncologists question its value, especially in the setting of minimal nodal disease.
October 10,by NCI Staff. New study results show that for women with early-stage breast cancer, having only a sentinel lymph node biopsy after lumpectomy, rather than a more aggressive biopsy procedure, did not decrease survival. Long-term results from a large clinical trial confirm that, for some women with early-stage breast cancer who have lumpectomy as their surgical treatment, a less extensive lymph node biopsy approach is sufficient.
