Measurement Requirements

This trial is evaluating whether Stereotactic Radiosurgery (SRS) will improve 1 primary outcome and 4 secondary outcomes in patients with Breast Cancer. Measurement will happen over the course of Up to 12 months.

Intracranial Progression Free Survival (PFS)
Intracranial Progression Free Survival: defined as the time from the date of start of treatment to investigator-determined date of progression or death due to any cause, whichever comes first. Progression will be determined by Response Assessment in Neuro-Oncology Brain Metastases (RANO-BM) Criteria.
Intracranial local brain tumor control
Intracranial local brain tumor control following SRS and abemaciclib will be determined from irradiated lesions according to RANO-BM criteria.
Overall Survival
Overall Survival is defined as the time from the start of treatment to death due to any cause.
Extracranial Progression Free Survival
Extracranial Progression Free Survival: Time from the date of start of treatment to the investigator determined date of progression (determined by RECIST) or death due to any cause, whichever occurs first.
Intracranial distant brain tumor control
Intracranial distant brain tumor control following SRS and abemaciclib will determined by the development of new lesions outside of the irradiated area.

What is the survival rate for breast cancer?

The survival rates of breast cancer patients are improving over the last decade, with an overall five-year survival rate of 72% for newly diagnosed cases in 2009 compared with 62% in 1998. This change is mainly driven by reductions in mortality among women younger than 50 years old.

What is the primary cause of breast cancer?

In a recent study, the data suggests that hormonal factors play the major role in development of breast cancers. It seems that both genetic and environmental factors contribute to development of breast cancers. Results from a recent clinical trial also show that the causative factors of breast cancers are changing due to modern environment and lifestyle changes. We believe that our work will help to develop new treatments of breast cancers.

Anonymous Patient Answer

How quickly does breast cancer spread?

Results from a recent paper give a more complete picture of how fast breast cancer spreads compared with what was found using only the data on distant metastases. For patients with localized disease, there is considerable variation in the rate of tumor progression between individuals.

Anonymous Patient Answer

What are the chances of developing breast cancer?

Results from a recent clinical trial suggests that among women born in Australia, the lifetime risk of developing breast cancer is 5.9%. There were no differences between men and women in terms of breast cancer risk.

Have there been any new discoveries for treating breast cancer?

There are numerous research findings that may pave the way for additional advances in the treatment of breast cancer. This article focuses solely on new advancements in the field of radiation therapy and chemotherapy.
