Study population: Postmenopausal, ER and/or PgR positive breast cancer patients eligible for adjuvant hormonal treatment (HT), who are admitted for treatment and follow-up at the participating sites, will be enrolled in the trial. Study subjects will be treated with standard adjuvant hormonal therapy for a total of 5 years or until disease relapse or until HT is permanently discontinued for other reasons. The choice of endocrine treatment strategy (drugs to be used or their sequence, if the sequential option has been decided) is left at the discretion of the participating site. Adjuvant HT will commence after the completion of adjuvant chemotherapy and/or radiotherapy.
Who may be able to join
- Postmenopausal status. ER and/or PgR status positive. Adjuvant hormonal treatment for 5 years according to standard practice has been decided by the treating physician. Values within normal limits for the blood coagulation parameters at baseline visit. Accessible for follow-up for the duration of the trial. Written informed consent.
Who cannot join
- Both ER and PgR negative primary tumor. Evidence of distant metastases (M1) Neo-adjuvant hormonotherapy. Chronic use of oral anticoagulants such as warfarin or acenocoumarol. Psychiatric disorders preventing proper informed consent. Concomitant malignancies except for adequately treated carcinoma in situ of the uterine cervix or basal squamous cell carcinoma of the skin.

About this study
Official title: An Observational, Prospective Cohort Study, on Blood Coagulation Parameters in Postmenopausal Patients With Operable Breast Cancer Who Are Treated as Per Standard Practice With Adjuvant Hormonal Therapy for a Total of 5 Years
The objective of the study is to monitor the changes of blood coagulation parameters in postmenopausal patients who are treated with adjuvant Hormonal Therapy for a total of 5 years. The values of the standard coagulation parameters throughout the study will be compared with the baseline values.
Read the detailed description
Study subjects will be treated with standard adjuvant hormonal therapy for a total of 5 years or until disease relapse or until HT is permanently discontinued for other reasons. The choice of endocrine treatment strategy (drugs to be used or their sequence, if the sequential option has been decided) is left at the discretion of the participating site. Adjuvant HT will commence after the completion of adjuvant chemotherapy and/or radiotherapy. Percentage change (%) from baseline of the blood coagulation parameters at 6, 12, 18, and 24 months of treatment. The blood coagulation parameters which will be measured are fibrinogen, prothrombin time (PT) and activated partial thromboplastin time (aPTT).

Clinical summary
The research question as the sponsor registered it. This describes what the study plans to test, not what it found.
The objective of the study is to monitor the changes of blood coagulation parameters in postmenopausal patients who are treated with adjuvant Hormonal Therapy for a total of 5 years. The values of the standard coagulation parameters throughout the study will be compared with the baseline values.
Detailed description
Study subjects will be treated with standard adjuvant hormonal therapy for a total of 5 years or until disease relapse or until HT is permanently discontinued for other reasons. The choice of endocrine treatment strategy (drugs to be used or their sequence, if the sequential option has been decided) is left at the discretion of the participating site. Adjuvant HT will commence after the completion of adjuvant chemotherapy and/or radiotherapy. Percentage change (%) from baseline of the blood coagulation parameters at 6, 12, 18, and 24 months of treatment.

The record lists no contact. The official record names the sponsor, who can be asked directly. AzTrials does not enrol participants or take referrals.
What does the primary outcome measure?
Percentage change (%) from baseline of the blood coagulation parameters (fibrinogen, PT, aPTT) at 6, 12, 18, and 24 months of treatment. (time frame: 2 years). It is what the study was designed to measure, not a finding.
Where can I read the original study information?
Does a listing mean the treatment is approved or proven to work?
No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.
How often is this information updated?
