Brief Summary
Patients enrolled in the study will be randomized before surgery: in one study arm, the search for lymph node metastases in surgically removed sentinel lymph nodes will occur using the ultrastaging method (standard), while in the other arm it will be conducted using the OSNA method.

Outcome Measures
Primary Outcomes (1)
Number of SLN metastasis detected by OSNA versus ultrastaging method
We will evaluate the number of lymph node metastases identified with both methods, in order to calculate the incidence of lymph node metastases for each group
From enrollment to the acquisition of the histological examination (8 weeks)
Secondary Outcomes (9)
Overall survival (measured in months) in patients with a diagnosis of lymph node metastases (identified with OSNA and ultrastaging), performing stratification by molecular class.
3 years (a 3-year follow-up is planned)
Disease-free survival (measured in months) in patients with a diagnosis of lymph node metastases (identified with OSNA and ultrastaging), performing stratification by molecular class.
3 years (a 3-year follow-up is planned)
3 year disease-free survival (measured in months) in OSNA versus ultrastaging negative patients
3 years (a 3-year follow-up is planned)
3 year overall survival (measured in months) in OSNA versus ultrastaging negative patients
3 years (a 3-year follow-up is planned)
5-year disease-free survival (measured in months) in OSNA versus ultrastaging negative patients
5 years
- +4 more secondary outcomes
