PROOFS-Registry - Premenopausal Women With Breast Cancer Optimally Treated With OFS
Germany1,470 participantsStarted 2022-12-07
Plain-language 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 data on the impact of postmenopausal status and/or use of OFS within 3-4 weeks endocrine induction therapy show relevant impact of OFS/postmenopausal status on Ki-67 response; also, secondary amenorrhea after (neo-)adjuvant chemotherapy was a positive predictor of outcome due to OFS \[8, 9\].
This registry will give insights in the real-world use of OFS and the effect of secondary amenorrhea in female pre- and perimenopausal patients with or without previous use of chemotherapy and with different endocrine treatments (ET +/- GnRH).
As adherence over time (5-10 years) plays a major role in the endocrine treatment, the registry will follow patients' treatments for up to 10 years and include QoL information.
Results of MammaPrint® (MammaPrint® Index) as indicating factor for chemotherapy use and risk classification, thus, choice of adjuvant treatment (chemotherapy, OFS combined with endocrine therapy, or endocrine therapy alone) will be correlated to outcome under real-world conditions.
Baseline, treatment, and relapse data shall be collected to gain further insight in the treatment paths, treatment adherence, and outcome of such patients.

Inclusion Criteria:
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 thera…
Questions worth asking your doctor
Bring these to your next appointment. They're a starting point for a shared conversation — not a sign you qualify or a recommendation to enrol.
1Based on my diagnosis and history, is this trial worth exploring for me — or is there a standard treatment we should try first?
2What does this trial's phase tell us about how much is already known about its safety and benefit?
3What would taking part actually involve for me — visits, tests, time, and travel?
4What are the known and possible risks or side effects I should weigh, and how would they be monitored?
5If this trial isn't the right fit, what other options or trials would you suggest I look into?
Generated to help you prepare — always confirm anything about your own eligibility and care with the study team and your doctor.
Questions for the trial coordinator
The trial coordinator is the person who runs the study day to day. These cover the practical side — logistics, costs, and what taking part would actually mean for your life. The study team confirms whether you meet the criteria; these are questions to ask, not a sign you qualify.
1What does taking part actually involve week to week — how many visits, where, and how long does each one take?
2What costs are covered by the study, and what might I have to pay for myself, including travel, parking, or time off work?
3What happens during screening, and what happens if the study team confirms I don't meet the criteria after those tests?
4Who pays for the scans, blood work, and other tests the trial requires — the study, my insurance, or me?
5How will being in the trial affect my regular care, and will my own doctor stay informed and involved?
6Can I leave the trial at any point if I change my mind, and what would happen to my care if I do?
A starting point for the conversation — always confirm anything about your own eligibility, costs, and care with the study team and your doctor.
