Assessment

Primary outcomes

Breast Cancer free interval (BCFI) defined as the time from enrollment in
the study to the first invasive BC event (local, regional, or distant
recurrence or a new invasive contralateral BC).

Key secondary outcomes

-Menstruation recovery and pattern.
-Pregnancy (determined by pregnancy test).
-Pregnancy outcome: full term pregnancy, caesarean section, abortion, miscarriage, ectopic, stillbirth.
-Offspring outcome: preterm birth, low birth weight, birth defects.
-Breastfeeding; pattern of breastfeeding (duration, use ipsilateral breast if previous breast conservation, side exclusivity).
-Use of assisted reproductive technology (ART).
-Adherence to endocrine treatment assessed by:
-- Treatment resumption after the ~2 year ET break.
-- Total duration of at least 5 years of ET.
-Distant recurrence-free interval (DRFI), defined as the time from
enrollment in the study to the first BC recurrence in a distant site, excluding second (non-breast) primary cancers and contralateral breast cancer.

plus SERM or AI) for >= 18 months but <=
30 months for early breast cancer.
-The adjuvant endocrine therapy must have stopped within 1 month prior
to enrollment.
-Patient wishes to become pregnant.
-Breast cancer for which patient is receiving endocrine therapy must have

positive, determined using immunohistochemistry (IHC)), and treated
with curative intent.
-Patient must be premenopausal at breast cancer diagnosis, as determined
locally and documented in patient record.
-Patient must be without clinical evidence of loco-regional and distant
disease, as evaluated according to institutional assessment standards and
documented in the patient record.
-Written informed consent (IC) for trial participation must be signed and
dated by the patient and the investigator prior to enrollment.
-Written consent to biological material submission, indicating the patient
has been informed of and agrees to tissue and blood material use, transfer

prior to any procedures specific for this trial.
-The patient has been informed of and agrees to data transfer and handling,
in accordance with national data protection guidelines.
-Patient must be accessible for follow-up.

-Patients with current local, loco-regional relapse and/or distant metastatic breast cancer.
-Patients with a history of prior (ipsi- and/or contralateral) invasive BC.
-Patients with previous or concomitant non-breast invasive malignancy.
-Exceptions are limited exclusively to patients with the following previous malignancies, if adequately treated: basal or squamous cell carcinoma of the skin, in situ non-breast carcinoma, contra- or ipsilateral in situ breast carcinoma, stage Ia carcinoma of the cervix.
-Concurrent disease or condition that would make the patient inappropriate for study participation or any serious medical disorder that would interfere with the patient's safety.
