What gene product is associated with BRCA1?
DNA repair protein (p.221)
What gene product is associated with BRCA2?
DNA repair protein (p.221)
What gene product is associated with BRAF?
B-raf (p.221)
What gene product is associated with NF1?
RAS GTPase activating protein (RAS-GAP) (p.221)
What gene product is associated with NF2?
Merlin (schwannomin) protein (p.221)
What gene product is associated with DPC4?
DPC (pneumonic- Deleted in Pancreatic Cancer) (p.221)
What gene product is associated with DCC?
DCC (pneumonic- Deleted in Colon Cancer) (p.221)
What is PSA used to follow?
Prostate specific antigen; used to follow prostate carcinoma (p.222)
In what conditions may PSA be elevated?
Prostate carcinoma, BPH, prostatitis (p.222)
What is the role of tumor markers in cancer diagnosis?
Should not be used as the primary tool for cancer diagnosis; tumor markers may be used to confirm diagnosis, to monitor for tumor recurrance, and to monitor response to therapy (p.222)
What is the tumor marker ‘prostatic acid phosphatase’ used to detect?
Prostate carcinoma (p.222)
What is the tumor marker CarcioEmbryonic Antigen (CEA) used to detect?
Very non specific marker- produced by 70% of Colorectal and Pancreatic cancers, but also produced by gastric, breast, and medullary thyroid cancers (p.222)
What is a-fetoprotein used to detect?
Hepatocellular carcinomas and nonseminomatous germ cell tumors (e.g. testis, ovary) (p.222)
Where is a-fetoprotein normally produced?
By the fetus (p.222)
What is b-gCG used to detect?
Hydatiform moles and choriocarcinomas; Gestational trophoblastic diseases (p.222)
