Trial summary

A history of breast cancer is a risk factor for the development of endometrial pathologies, such as typical and atypical glandular hyperplasia, endometrial polyps, uterine fibroids, endometrial adenocarcinoma and uterine sarcoma, probably due to some common risk factors (eg. obesity, nulliparity).

About this study

Official title: Evaluation of Endometrial Changes in Breast Cancer Women With or Without Hormonal Therapies

A history of breast cancer is a risk factor for the development of endometrial pathologies, such as typical and atypical glandular hyperplasia, endometrial polyps, uterine fibroids, endometrial adenocarcinoma and uterine sarcoma, probably due to some common risk factors (eg. obesity, nulliparity). Even if ethiopathogenesis for breast cancer and endometrial pathologies is not well established, both genetic factors and hyperestrogenic state may be play a pivotal role for their development. Indeed, relative hyperestrogenism is also the main target for the treatment of breast cancer. Currently used therapies for this purpose are selective estrogen receptor (ER) modulators (SERMs), such as Tamoxifen (TAM), and third generation non-steroidal aromatase inhibitors (AIs), such as letrozole and anastrozole.

TAM has both agonist and antagonist properties, depending upon the individual target organ and circulating levels of serum estrogens: on the one hand, it blocks estrogen stimulation in breast tissue; on the other hand, TAM shows an ER agonist activity in the endometrium that is able to stimulate proliferation and, in some cases, it causes an increased risk of uterine pathologies. Women with hormone-dependent breast cancer have to use TAM for five to ten years. Many reports suggest that the risk of uterine pathologies increases with the time of administration.

Considering these elements, the primary aim of this study will be to investigate the incidence of endometrial pathologies, especially of endometrial cancer, in different groups of breast cancer women undergoing diagnostic hysteroscopy.

Questions about this trial

What is this clinical trial studying?

An observational study of Breast Cancer and Endometrial Cancer, run by Università degli Studi dell'Insubria.

The full registered description is in the About this study section and the official record.

Who may be eligible to take part?

The sponsor lists 1 inclusion and 5 exclusion criteria. Eligibility is decided by the study team after screening, so read the full criteria and contact a listed site.

Is this clinical trial currently recruiting?

The record says: finished, as of the sponsor's last update on 25 Mar 2020. Status can change between updates, so confirm with the study contact before making plans.

What are the possible benefits and risks?

They depend on the study and the treatment, and no study can promise a benefit. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.

Are results available for this study?

The study is completed, but results are not available in the source record. That does not mean the treatment did or did not work.

How can a doctor refer a patient or contact the research team?

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?

Endometrial pathologies (time frame: 5 years after breast cancer surgery). It is what the study was designed to measure, not a finding.

Where can I read the original study information?

On the ClinicalTrials.gov record for NCT03898947, which also lists 1 linked publication.

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?

AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 25 Mar 2020.
