recurrent breast cancer
The term recurrent breast cancer in medical imaging is given to recurrence of malignancy within the same breast at or close to the resection bed more than two years following surgical excision.
Epidemiology
The rate of local recurrence may be as high as 19% in 10 years. The maximum for recurrence occurs ~4-6 years post treatment.
Pathology
Risk factors
Recognized risk factors include:
- close +/- positive margins at time of resection
- extensive intraductal components (EIC)
- inadequate adjuvant radiation therapy
- young age at initial presentation
- multicentric breast cancer
- multifocal breast cancer
Radiographic features
Mammography
On mammography, the appearance of recurrent breast cancers are generally thought to be mammographically similar to the original breast tumor .
Breast MRI
MRI offers an advantage over conventional methods in assessing recurrence. This can be seen in evaluating of tumor recurrence versus scarring where enhancement in the post-surgical scar should decrease substantially over the first 2 years. The presence of enhancement at the lumpectomy site after ~18 months since surgery is considered a concerning feature for recurrent breast cancer.
