Summary
Definition
History and exam
Key diagnostic factors
- presence of risk factors
- bone pain
- pleural effusion
- palpable mass after treatment of the primary tumour
Other diagnostic factors
- shortness of breath
- cough (non-productive)
- anorexia
- weight loss
- neurological symptoms (e.g., neuralgic pain, weakness, headaches, seizures)
Risk factors
- female sex
- age >50 years
- family history of breast and/or ovarian cancer
- breast cancer susceptibility genes (BRCA1, BRCA2, CDH1, PALB2, PTEN, STK11, and TP53)
- tumour >5 cm in diameter
- high number of positive axillary lymph nodes (e.g., >10)
- lymphovascular invasion
- high-risk 70-gene signature
- high-risk 21-gene signature
- high-risk PAM50 gene signature
- Lynch syndrome (hereditary non-polyposis colorectal cancer)
- CHEK2 mutations
- ATM mutations
- minimal residual disease (MRD)
- bone metastasis and lung metastasis gene signatures
Diagnostic investigations
1st investigations to order
- FBC
- LFTs
- calcium
- CT (of chest and abdomen)
- bone scan (scintigraphy)
Investigations to consider
- MRI (focused on area of concern, e.g., brain, spinal cord, bone)
- PET/CT scan
- biopsy of metastatic lesion
- high-penetrance breast cancer susceptibility genes
- additional biomarker testing
- echocardiogram
- multi-gated acquisition (MUGA) scan
- pleural cytology
