Summary
This trial is comparing radiation therapy alone to radiation therapy with lymph node dissection in treating breast cancer patients who have already had chemotherapy and surgery.
Who is the study for?
This trial is for breast cancer patients who've finished chemotherapy and surgery, with certain hormone receptor statuses checked. They should have a performance status of 0-1, indicating they're fully active or restricted in physically strenuous activity but ambulatory. Participants must not be pregnant, have no history of invasive cancer in the opposite breast within 5 years (except certain skin cancers or cervical carcinoma in situ), and no prior radiation therapy.
What is being tested?
The study compares two approaches after chemotherapy and surgery: one group undergoes axillary lymph node dissection (ALND) where lymph nodes are surgically removed; another receives only axillary radiation therapy to destroy any remaining cancer cells. The goal is to determine which method is more effective for treating breast cancer that has spread to nearby lymph nodes.
What are the potential side effects?
Potential side effects from ALND may include pain, swelling, limited arm movement, nerve injury causing numbness or weakness, and risk of lymphedema (arm swelling due to fluid buildup). Radiation therapy might cause skin changes like redness and irritation, fatigue, arm swelling as well as a slight risk of secondary cancers.

Trial Design
2Treatment groups
Experimental Treatment
Group I: Arm 2: Axillary radiation and nodal radiation therapyExperimental Treatment2 Interventions
Radiation Therapy: Radiation is delivered to the breast/chest wall, full axilla including Levels I, II, III, supraclavicular nodes and internal mammary nodes in the first 3 intercostal spaces. Treatment will be given 5 days a week over 5-6 weeks.
Group II: Arm 1: ALND + nodal radiation therapyExperimental Treatment2 Interventions
Surgery: For patients randomized to axillary lymph node dissection (ALND), it is recommended that a complete level I and II dissection with resection of minimum of a total of 8 lymph nodes (SLN and ALND together) be done. Level III dissection is not required, but may be performed at the discretion of the surgeon. If fewer than 8 lymph nodes (SLN and ALND together) are resected, then the patient will discontinue protocol treatment.
Radiation Therapy: Radiation is delivered to the breast/chest wall, undissected axilla, supraclavicular nodes and internal mammary nodes in the first 3 intercostal spaces. Treatment will be given 5 days a week over 5-6 weeks.
