  • Title: Multimodality approach to early-stage non-small cell lung cancer.
    Author: Scagliotti G.
    Journal: Lung Cancer; 2007 Aug; 57 Suppl 2():S6-11. PubMed ID: 17686446.
    Abstract:
    The results of large randomised studies have clearly demonstrated that adjuvant chemotherapy prolongs overall survival by approximately 5% at 5 years in patients with early-stage non-small cell lung cancer (NSCLC). The benefit appears to be largely confined to patients with stage II/III disease, although approximately 25% of patients with stage I disease are at high risk of relapse within 5 years of surgery and therefore could benefit from adjuvant chemotherapy. There is an urgent need to predict more accurately which patients are likely to relapse after surgery and who, therefore, might benefit from further therapy. Preliminary studies indicate that molecular tumour markers may be able to identify tumours that are more likely to respond to chemotherapy and patients who are more likely to achieve improved survival from those who do not benefit at all from adjuvant chemotherapy. A pivotal study has shown that analysis of tumour gene expression can be used to predict the risk of relapse with greater accuracy than that which is achievable using clinical factors. In the future, pharmacogenomics may be used in this approach to identify patients for adjuvant chemotherapy, thus increasing the efficacy of treatment and reducing the burden of therapy in patients who are unlikely to benefit from further therapy.
