Popis: Lung cancer remains one of the greatest medical challenges with nearly 1.5 million new cases worldwide each year and a growing tobacco epidemic in the developing world. This review summarizes briefly the current status in growing areas of clinical research. The value of screening for early disease is not yet established and trials to see if mortality can be improved as a result are in progress. Better and more accurate staging will both streamline investigation and prove cost-effective once ultrasound-guided biopsy and aspiration of mediastinal nodes become universally accepted. This, allied to the new staging classification, will improve selection of cases for surgery, intensive multimodality therapy and for adjuvant treatment postoperatively. Much still needs to be done to refine staging as within a particular stage group, the outcome shows great variation. More information is needed on the genetic make-up in some groups of tumours and not just their size; that is, more biological data on tumour growth patterns are likely to be at least as discriminating. The place of the stem cell theory of tumorigenesis is also explored in this paper. Finally, targeted therapy for advanced non-small-cell lung cancer is highlighted as a development with early promise, but still much clarification is required, before it can be considered as a universal approach in late disease.
