Introduction:
Despite increasing use of thoraco-abdominal CT where incidental breast cancers could be discovered, few studies report incidental breast cancer detection. This study evaluates the pattern and rate of CT detected breast cancer.
Methods:
Ethically approved retrospective review of all breast cancers detected at Letterkenny Hospital between January 2010 and December 2015 was undertaken. Patients having CT scans from outside the area were not included. Patient demographics, reason for CT, technical aspects of the CT were recorded. A GE V-CT64 Slice Scanner, and 2 GE Light Speed16 Slice Scanners were used, a total of 3919 CT scans were analysed by 6 consultant radiologists. Lesions were classified according to their morphology.
Results:
Of 483 new cancers 19 were CT detected, all female, mean age 70.2 (±11.9; range 47-87 years). CTs were performed for cancer staging or follow up in 6, GI symptoms in 7, renal 1, spine 1 and respiratory 4. 11 patients had CT abdomen thorax, 6 had thoracic scans, 2 had abdominal CTs. Physical examination revealed a lump in 14/19. 14 patients were found to have invasive ductal carcinomas, 4 invasive lobular carcinomas, 1 invasive tubulolobular carcinoma. CT scan tumour size was 20.44mm ±12.4 (range 7–48mm). 15/19 were irregular or spiculated on CT. 8/19 patients were node positive.
Conclusion:
This study identified 3.9% of breast cancers are now incidentally detected on CT, with typical irregular features on 80%. Protocols should be developed for routine documentation of chest CT for patients aged over 50 to potentially increase detection of breast cancer
