Is histologic grade an independent prognostic factor for survival in non-small cell lung cancer : an analysis of 5018 hospital- and 712 population-based cases?
Histologic grade has significant prognostic value for survival of patients with non-small cell lung cancer. Histologic grade may provide useful information in defining the aggressiveness of tumors and should be considered as an independent factor affecting survival beyond TNM staging.
Lycopene exposure can suppress phosphatidylinositol 3-kinase-dependent proliferative and survival signalling in androgen-responsive LNCaP and androgen-independent PC3 cells suggesting that the molecular mechanisms for the cytostatic and cytotoxic actions of lycopene involve induction of G0/G1 cell cycle arrest. This study supports further examination of lycopene as a potential agent for both the prevention and treatment of prostate cancer.
