Because the patient characteristics were well balanced, any decrease in disease-free survival or overall survival in the SLND alone group would have been anticipated to occur due to an acosog z0011 trial in regional recurrences; however, only a single regional recurrence was observed in the SLND alone group with additional follow-up in the ACOSOG Z Alliance trial.
Among women with T1 or T2 invasive primary breast cancer, no palpable axillary adenopathy, and 1 or 2 sentinel lymph nodes containing metastases, year overall survival for patients treated with sentinel lymph node dissection alone was noninferior to overall survival for those treated with axillary lymph node dissection. All other disease sites were defined as distant metastases. A population-based study of the effects of a regional guideline for completion acosog z0011 trial lymph node dissection acosog z0011 trial axillary surgery in patients with breast cancer.

Due to the significant morbidity of ALND, including paresthesias, lymphedema, seroma, and higher rates of wound infection, identification of judiciuos use of the procedure has been an area of active interest.
This confirms that although distant recurrence among hormone receptor—positive tumors is a later event, nodal recurrence among these patients is primarily an early event.
Enrollment of patients in 4 acosog z0011 trial with a minimum follow-up period of 5 years was initially planned. Axillary dissections are associated with considerable morbidity, and the results of this trial demonstrated that this morbidity can be avoided without decreasing cancer control.
Randomized phase III trial to determine the effectiveness of removing lymph nodes in the armpit in treating women who have stage I or stage IIA breast cancer. Patient who is noted to have matted nodes or gross extranodal disease at acosog z0011 trial time of SLND.
Patients who were lost to follow-up ie, missing data were censored at the time of their last follow-up in the time-to-event analyses disease-free survival and overall survival.

Among women with T1 or T2 invasive primary breast cancer, no palpable axillary adenopathy, and 1 or 2 sentinel lymph nodes containing metastases, year overall survival for patients treated with sentinel lymph node dissection alone was noninferior to overall survival for those treated with axillary lymph node dissection. Patient acosog z0011 trial a medical contraindication to ALND or is considered a poor surgical risk due to a non-malignant systemic disease cardiovascular, renal, etc.
Patient is lactating breastfeeding. None Open Label Primary Purpose: Before publication of the initial ACOSOG Z trial results, 9 there was a general consensus that axillary dissection was acosog z0011 trial for better cancer control when metastases were identified in sentinel lymph nodes.

Third-field radiation was prohibited. Axillary lymph a0011 dissections ALND have historically been a means of maintaining regional control of breast cancer, especially in patients with initial presentation of metastatic lymph node disease.

There were no differences in acosog z0011 trial of 5-year survival Back to top Article Information.
All patients underwent lumpectomy and tangential whole-breast irradiation. Targeted enrollment was women with final analysis after deaths, but acosog z0011 trial trial closed early because mortality rate was lower than expected.
