Is immunosuppression an independent prognostic factor associated with aggressive tumor behavior in cutaneous melanoma?
The study is retrospective and has a small sample size.
Treatment with CPT effectively inhibited the growth of the human gastric cancer SIIA; the mechanism involved was induction of apoptosis mediated by up-regulation of p53, p21Waf1/Cip1, and p27Kip1 and the down-regulation of Bcl-2 and Bcl-XL. Novel agents such as CPT, which target specific molecular pathways, may prove clinically useful in the adjuvant treatment of gastric cancers.
