Omitting axillary surgery after chemotherapy for certain breast cancer patients
Official title: Breast Carcinoma T1-T2-T3 / cN +: Axillary Conservation of Lymph Nodes in the Presence of Micro Metastases in Sentinel Lymph Node, in cN- After Neoadjuvant Chemotherapy - Studio NEONOD 2
Run by Istituto Clinico Humanitas · NCT04019678 · Data updated 2026-11-12
This study is testing if women with certain breast cancer can skip surgery on their lymph nodes after chemotherapy and still do just as well.

Is this trial a fit for you?
✓Likely a good fit
Ideal candidates are women aged 18 to 75 with infiltrating breast carcinoma and positive axillary lymph nodes who have undergone neoadjuvant chemotherapy and show negative lymph nodes post-treatment.
✕Probably not a fit
Patients with inflammatory breast cancer, in situ breast cancer, or those with significant co-morbidities that prevent follow-up or adjuvant therapy may not benefit from this study.

What this trial studies
This clinical trial investigates whether patients with micro metastatic sentinel lymph nodes can safely avoid axillary lymph node intervention after receiving neoadjuvant chemotherapy. It is a multicentric study conducted in Italy, comparing outcomes between patients who undergo axillary treatment and those who do not, based on their sentinel lymph node status post-chemotherapy. Participants will be monitored for five years to assess survival rates and recurrence risks, with a focus on ensuring that omitting surgery does not negatively impact patient outcomes.
Why it matters
Potential benefit: If successful, this approach could reduce the need for invasive surgeries in breast cancer patients, leading to improved quality of life and fewer complications.
How similar studies have gone: While similar approaches have been explored, this specific methodology of omitting axillary dissection in this patient population is relatively novel and has not been extensively tested.
