New strategies in the treatment of resectable non-small cell lung cancer.
Non-small cell lung cancer is a systemic illness. Given the systemic nature of lung cancer, it seems that chemotherapy should play an essential role. In stage IIIA disease neoadjuvant chemotherapy plus surgical resection improves survival when compared with surgical resection alone. However, randomized trials using postoperative adjuvant chemotherapy with 'older' drugs has shown no substantial improvement in survival. Since new chemotherapeutic agents may provide additional benefits, there are various studies incorporating new agents in the resectable disease treatment setting. One focus for ongoing research is to find better treatment approaches in earlier stages of disease. Some data suggest that induction chemotherapy in stage I-II is feasible and appears not to compromise surgery. Another promising more individual approach is to tailor chemotherapy according to the pattern of genetic variants or abnormalities found in DNA and/or RNA extracted from the bloodstream. Furthermore, at present many types of new agents are available for testing as 'consolidation treatment' following induction treatment, including, angiogenesis inhibitors, antibodies to growth factor receptors, gene therapy and vaccines.
