Alterations in the androgen receptor are associated with endocrine treatment outcomes. This study demonstrates that it is possible to identify different types of alterations via simple blood draws. Follow-up studies are needed to determine the effect of such alterations on hormonal therapy.

Comparison of GEM with cisplatin-based therapy in symptomatic, advanced NSCLC demonstrates that GEM produces significantly a stronger and longer-lasting clinical benefit, probably due to its equal effectiveness in terms of ORR, time-to-progression or survival, combined with significantly less severe therapy-related toxicity.

CTC dynamics during therapy are associated with PSA response and provide independent clinical prognostication over PSA declines. Hence the study demonstrates the pharmacodynamic properties of CTCs.
