Methods
This is an observational retrospective study analyzing the outcome of all women treated with conservative breast therapy and attended for their post-conservative follow-up/screening mammography as a part of an IRB-approved screening protocol at the breast imaging unit, Women and Fetal Imaging (WAFI) clinic, in Cairo, Egypt.
These women had at least 2 follow up mammography visits registered at the clinic during the years of 2007– 2017.
Women with no follow-up registered after their initial diagnoses, or only one short term follow up visit with negative results, or had a previous history of contra-lateral mastectomy were excluded.
Data collected include:
- Age
- Family history
- BMI
- Reproductive history
- Mammography assessment final results (including breast density)
- Date of initial diagnoses of breast cancer.
- Date of recurrence incidence.
- Primary tumor characteristics
- Routine history and physical examination charts.
The main outcome measures:
- Identifying the Incident of local recurrence and time difference since the first cancer (disease free survival).
- Mammography findings at the incidence of recurrence.
- The local recurrence rate (LRR) in correlation to the patient and tumor factors.
