This article deals with hereditary breast cancer.
Familial breast cancer redirects to this article.
Syndromes associated with breast cancer
| Gene | Syndrome | Cancers | Notes |
|---|---|---|---|
| BRCA1 | Familial breast and ovarian cancer[1] | breast, male breast, ovarian, prostate, pancreas, fallopian tube | younger individuals vis-à-vis BRCA2 |
| BRCA2 | Familial breast and ovarian cancer 2[2] | breast, male breast, ovarian, prostate, pancreas, stomach, melanoma, gallbladder, bile duct, pharynx | older individuals vis-à-vis BRCA1 |
| TP53 (p53) | Li-Fraumeni syndrome (AKA SBLA syndrome) | sarcomas, brain, larynx, lung, leukemia, adrenal, breast | often present in childhood |
| CHEK2 | Li-Fraumeni syndrome (variant) | see p53 | - |
| STK11 | Peutz-Jeghers syndrome | breast, gastrointestinal, Sertoli cell tumour, granulosa cell tumour, SCTAT | characteristic GI hamartomas, mucocutaneous pigmentation |
| PTEN | Cowden syndrome | breast, thyroid (PTC), endometrial, renal, colorectal | - |
| CDH1 | Familial diffuse gastric cancer[3] | invasive lobular carcinoma, gastric signet ring cell carcinoma | - |
BRCA1 and BRCA2
BRCA1 versus BRCA2:[4]
| Gene | Age | Histology | Other cancers |
|---|---|---|---|
| BRCA1 | younger | worse types, e.g. triple negative breast ca. | uterine tube |
| BRCA2 | older | sporadic types | stomach, melanoma, gallbladder, bile duct, pharynx |
Types of cancer associated with both BRCA1 and BRCA2 - male OPP:
- Male breast, ovarian, prostate, pancreas.
How to remember types of cancer associated with BRCA2 - PUM:
- Pharynx, upper GI (stomach, gallbladder, biliary), melanoma.
Management
- Women get prophylatic bilateral salpingo-oophorectomies and mastectomies.
- The pathology yield in bilateral salpingo-oophorectomies is significant but modest; in series of 26 prophylatic surgeries (BRCA1 22 individuals, BRCA2 4 individuals) there were 2 in situ carcinoma and 2 atypical proliferations.[5] All of the pathology was in BRCA1 carriers.
- In prophylatic procedures, the ovaries and tubes, endometrium, and lower uterine segment should all be submitted in total.[6]
- Poly(ADP-ribose) polymerases (PARP) inhibitors, e.g. olaparib.[7]
- Used in both germline and somatic BRCA-mutated cancers.
