[摘要]：Areas covered in this review: Diagnosis of NSCLC histotype is becoming extremely important to address treatment. While non-squamous histology could start to benefit from the administration of several new drugs only recently, non-adenocarcinoma subtype seems to benefit from the administration of figitumumab (CP-751,871) a fully human anti-IGF 1 receptor (IGF-1R) mAb. In this paper, we reviewed the IGF-1R pathway and its inhibitors. What the reader will gain: Approaches targeting IGF-1R include small-molecule IGF-1R tyrosine kinase inhibitors (TKIs), which are in preclinical and early clinical phases of development, and the mAbs, among which figitumumab is being investigated in Phase III trials of advanced NSCLC. Take home message: Figitumumab reported interesting results in the treatment of advanced non-adenocarcinoma NSCLC patients. Overall, in order to administer the optimal treatment to patients, a more definite histological diagnosis is mandatory. |
