This is a multicenter, cohorts study to collect information from patients diagnosed with early-stage invasive breast cancer who have been previously included in a neoadjuvant or adjuvant clinical trial of the GEICAM group. Patients will be included in this study from the moment of completion of the follow-up of the studies of origin and will be followed for approximately 30 years
One consequence of the improvement in survival rates of certain tumors such as breast cancer is the increase in the number of patients available for long-term follow-up in randomized controlled clinical trials. This long follow-up allows an additional long-term evaluation of the efficacy, as well as of the sequelae related to the treatments that may occur beyond the time of the primary analysis. The target population of the study are all patients who were included in neoadjuvant and adjuvant clinical trials of GEICAM performed by the goup since 1998 in the medical oncology units of the participating sites, ensuring a follow-up of patients of approximately 30 years. This will allow to describe the long-term evolution of the patients with invasive breast cancer in early stages. The information obtained will be very useful to professionals involved in the diagnosis, treatment and monitoring of breast cancer, hospital managers, patients with this condition and society in general. This study provides data of great interest for the estimation of long-term disease requirements.

Event Free Survival (EvFS) in neoadjuvant studies.
The EvFS, is defined as the time from the randomization of the patients in the studies of origin, to the date of one of the following events: * Disease progression during neoadjuvant treatment. * Disease relapse (local, regional or distant) after curative surgery. * Second primary tumors * Death due to any cause.
Time frame: Throughout the whole follow up. Up to 30 years from the beginning of the Study approximately.
Disease Free Survival (DFS) in adjuvant studies.
DFS is defined as the time from the date of randomization of patients in the studies of origin, to the date of one of the following events: * Disease relapse (local, regional or distant) after curative surgery. * Second primary tumors * Death due to any cause.
Time frame: Throughout the whole follow up. Up to 30 years from the beginning of the Study approximately.
Overall Survival (OS).
Overall Survival (OS) defined as the time from the date of study enrolment to the date of death from any cause.
Time frame: Throughout the whole follow up. Up to 30 years from the beginning of the Study approximately.
