摘要: Abstract Objectives: Growth signaling is instrumental in tumor development. Insight into pathways by molecular and cellular biology has changed the development of new anticancer agents. Outside field urology specifically targeted drugs such as imatinib mesylate gefitinib showed impressive activity chronic myeloid leukemia non-small cell lung cancer, respectively. Methods: Literature search PubMed documented publications abstracts from meetings. Results: Preclinical data prostate cancer shows upregulation a wide variety growth factors their receptors PDGF, EGF, IGF, FGF, VEGF suggesting efficacy agents targeting these pathways. Here preclinical evidence first clinical on use signal reviewed. Although some transduction inhibition monotherapy was reported, combination with chemotherapy radiotherapy seemed most promising cancer. Conclusion: So-called smart are small molecules at specific These will dominate trials years to come either single-drug modality, but more likely treatment.
