Brief Summary:
Today, the majority of clinically node positive (cN+) breast cancer patients is treated with neoadjuvant systemic therapy (NST). Axillary staging and treatment after NST in cN+ patients are areas of controversy. Patients with a pathological complete response (pCR) of the axillary lymph nodes are not expected to benefit from axillary lymph node dissection (ALND). Hence, less invasive axillary staging procedures are being introduced to avoid unnecessary ALND. However, evidence supporting the safety of replacing ALND by less invasive techniques in terms of oncologic safety and impact on quality of life (QoL) is lacking.
Detailed Description:
The MINIMAX is a multicenter registry study that includes node positive breast cancer patients, who are treated with NST (chemotherapy and ± immunotherapy), in order to gain insight in the oncologic safety and impact on QoL of less and more invasive axillary staging and treatment strategies.
Patients who are included in this study will complete Patient Reported Outcome Measures (PROMs) at baseline (time of diagnosis), and 1 and 5 years after diagnosis to assess impact on QoL.
A database will be built by the Netherlands Cancer Registry. Data on patient-, tumor-, pre-NST staging-, post-NST staging- and treatment-characteristics will be retrieved from patients' records by trained data registrars of the Netherlands Comprehensive Cancer Organisation (IKNL) using electronic case report forms (eCRFs). Five-year survival and recurrence will be evaluated to determine oncologic safety.
The results will be incorporated in the national guidelines. In case of an equilibrium between less and more invasive strategies, the data of this study will at least be extremely suitable to be used in the shared decision making process.
