October 10,by NCI Staff, papers on breast cancer. 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, papers on breast cancer, a less extensive lymph node biopsy approach is sufficient.
The trial showed that women with early-stage breast cancer who have cancer cells in one or two sentinel lymph nodes can skip axillary lymph node dissection ALND after breast-conserving surgery without affecting their long-term survival.
The findings are important for papers on breast cancer because ALND can cause chronic side effects such as numbness, decreased range of motion in the upper body, and lymphedemasaid Armando Giuliano, M. The trial results were published September 12 in JAMA. The axillary lymph nodes run from the breast tissue into the armpit. Early theories of breast-cancer metastasis held that cancer cells that had broken free from the main tumor would first travel through these lymph nodes on their way to other organs.
That led doctors to believe that removing the axillary lymph papers on breast cancer could reduce the risk of both cancer papers on breast cancer and metastases. However, more-recent research has suggested that breast cancer may metastasize to other areas of the body through several different routes, explained Dr.
Also, modern treatment for early-stage breast cancer typically includes radiation therapy—which targets some of the same lymph nodes—along with breast-conserving surgery, Dr.
Giuliano added. Most patients additionally receive some sort of systemic treatment, such as hormone therapychemotherapy, and, more recently, targeted therapyall of which can kill cancer cells throughout the body. The trial, called ACOSOG Zwas designed to compare whether sentinel lymph node biopsy SLNB alone provided equivalent survival benefits to ALND after breast-conserving surgery among a subset of women who also received radiation and systemic therapy.
The research team enrolled participants into the study from to Women who had stage I or II cancer and metastases in only one or two sentinel nodes were eligible to join the study. All women had undergone SLNB at the time of breast-conserving surgery. Half of the trial participants received no further surgery, and the other half underwent ALND. In the initial results from the trial, published in andwomen who had only SLNB did not have worse overall survival than women who underwent full ALND, papers on breast cancer.
The two groups also had papers on breast cancer rates of disease-free survival and cancer recurrence in the lymph nodes. However, the cancer research community had lingering concerns about the trial, the authors of the new paper explained.
For example, the papers on breast cancer recruited fewer participants than initially planned. In addition, far fewer women papers on breast cancer expected in both arms of the trial had any recurrence of their disease, making statistical comparisons between the groups difficult.
Most participants also had hormone receptor-positive breast cancer, which can recur many years after initial treatment. However, after 10 years of follow-up, the initial results held: only about 50 women had died papers on breast cancer any cause in each group. Overall survival was Rates of negative side effects from surgery were much higher in the ALND group, with 70 percent of women experiencing wound infection, delayed healing, or pain compared with 25 percent of women in the SLNB-alone group.
In addition, more women in the ALND group reported lymphedema. The researchers reported complete data on side effects seen during the trial in a previous paper. The results should not be used to direct the care of women with palpable axillary lymph nodes, women who had breast tumors larger than 5 cm in diameter, women with three or more positive sentinel lymph nodes, women who received chemotherapy or hormone therapy before surgery, and women who underwent mastectomy instead of breast-conserving surgery with radiation, they wrote.
One trial, currently underway in Europeis examining whether ALND can be skipped in some women who have a mastectomy for early-stage breast cancer, but results are not expected for years.
