Eligibility:

Brief Summary

There is only limited data for premenopausal patients in general, as well as for differences in the use of OFS in the subgroups of pre- and perimenopausal patients, respectively. The WSG ADAPT trial d...

This registry aims * to confirm an excellent outcome in pre-/perimenopausal patients treated by endocrine therapy (+ ovarian suppression) in patients with low genomic risk by MammaPrint® without chem...

Eligibility Criteria

Inclusion

  • Patients are eligible for participation in the registry only if they meet all the following criteria:
  • Female breast cancer patients
  • Pre- or perimenopausal at registry entry (age \<60 years and state after hysterectomy or amenorrhea for \<12 months; confirmation by blood hormone levels (FSH and estradiol in premenopausal range as per local normal range) recommended)
  • Primary tumor diagnosis not older than three months prior to inclusion (primary diagnosis defined as date of initial tumor biopsy)
  • Estrogen- and/or progesterone-receptor-positive/HER2 negative early breast cancer without any clinical signs of metastases
  • Adequate risk for recurrence:
  • intermediate clinical risk for recurrence, defined as (clinical in case of neoadjuvant treatment):
  • c/pT1 and
  • c/pN0 and
  • Ki-67 15-24% or
  • G2 or
  • patients, who do not meet these criteria but are at intermediate clinical risk for recurrence at investigator decision (e.g., very young age, low expression of hormone receptors, existing co-morbidities, familial cancer burden, etc.) can be included on individual decision basis or
  • high clinical risk for recurrence, defined as either (clinical in case of neoadjuvant treatment):
  • c/pT2-4 or
  • c/pN1 or
  • Ki-67 ≥25% or
  • G3
  • Low genomic risk of recurrence by MammaPrint® (tested on treatment naïve tumor specimen)
  • Luminal-type by BluePrint®
  • Treatment according to standard-of-care (e.g., AGO Guidelines) planned or started (until completion of local therapy the latest (including started or completed endocrine induction therapy), started, or planned adjuvant or neoadjuvant treatment)
  • Availability of untreated tumor material (core biopsy if preoperative endocrine therapy performed or neoadjuvant treatment intended or surgery specimen)
  • Capability to give written informed consent
  • Nodal positive patients will be accepted to the registry up to 25% of the genomic low/ultralow-risk population (n=441).

Exclusion

  • Patients will not be eligible for the registry for any of the following reasons:
  • Any other genomic testing, besides MammaPrint®, has been performed on the tumor material
  • Medical or psychological conditions that would not permit the patient to sign informed consent
  • Legal incapacity or limited legal capacity
  • Current participation in any interventional clinical trial which tests anticancer drugs, immunotherapeutics, or antibody treatment for any type of neoplasm
  • Non-compliance of the patient
