Check patient tumors express or contain (gene) mutations in the following:
EGFR (Epidermal Growth Factor Receptor - wild-type or mutant type)
VEGFR 1, 2 and 3 (Vascular epithelial growth factor receptor 1, 2 and 3)
C-Kit (tyrosine kinase growth factor receptor for stem cell factor) the cancer drug Gleevec works by targeting this receptor - SCLC and non-SCLC are known to make this receptor, not all but some
PDGF (Platelet growth factor receptor)
Multiple kinases inhibitors like sunitinib (sutent) or sorafenib, sunitinib works on VEGFR2 and PDGFR, as well as inhibiting c-KIT, FLT-3, and RET ; gleevec (STI571 or Imatinib) works on C-kit, PDGF; or Vandetanib (ZD6474) ZD6474 is an oral inhibitor of VEGFR2, EGFR, and RET; it is being tested in multiple clinical trials in lung cancer.
HER2 (Human epidermal growth factor receptor 2) some lung cancers have mutations on the HER2, it seems to mutate a lot with asian, non-smoker, women with lung cancer - then you can treat it with Herceptin or lapatinib (Tykerb).
Some doctors might not know all of this, if they dont update their current knowledge... but nothing wrong to ask and insist for gene mutation express test... Dont GIVE UP or HOPE...
May God bless all suffering cancer disease patients.
