Worldwide, pulmonary cancer remains the most common reason for cancer death, and at the time of diagnosis the most of patients will develop advanced or inoperable disorder. In addition to the symptom relief, platinum-based treatment, when given to people suffering from advanced non-small-cell lung cancer, provides a significant advantage of life expectancy.

Nevertheless, there are a few indications that a therapeutic plateau has been achieved with the modern chemotherapy options, and new effective treatment approaches are urgently required.
