PHILADELPHIA Men whose prostate cancer screenings show high grade prostatic intraepithelial neoplasia (HG-PIN) may find themselves in limbo, stuck between diagnoses they are told prostate cancer has not yet developed, but it might, and they are advised to undergo repeated needle biopsies as a precaution.
SEATTLE Therapies under development to treat prostate cancer by inhibiting the ability of insulin-like growth factor (IGF-1) to activate its target receptor could have unexpected results especially if a major tumor suppressor gene p53 is already compromised, according to new research by investigators at Fred Hutchinson Cancer Research Center.
