title: [The position of neoadjuvant chemotherapy in the treatment of non-small-cell lung carcinoma].
abstract: Surgical treatment of patients with non-small-cell lung carcinoma (NSCLC) offers greatest chances for long-term survival. However, the treatment is applicable only to patients diagnosed at an early stage of the disease, i.e. at stage I or II. The five year survival rate of patients operated at stage IIIA is as low as 23%. Hence there is a great need for improving survival results, especially in the sphere of systemic chemotherapy, as most tumour relapses involve the formation of metastases. Even though neoadjuvant chemotherapy in the operable stages of NSCLC still appeared very promising as a method of treatment a couple of years ago, recently published results have shown that its role has not yet been fully clarified and is still a subject of research. Additional results from randomised studies are necessary before neoadjuvant therapy may become a treatment standard. The dilemma as to whether or not to apply adjuvant, neoadjuvant or both types of chemotherapy in patients operated on for NSCLC therefore remains unsolved. On the whole, the positive role of neoadjuvant chemotherapy does not appear to be proven in the treatment of operable stage I and II NSCLS. In contrast, results of randomised studies first published in 2004 were in favour of post-surgical adjuvant chemotherapy as opposed to surgical treatment alone in NSCLC stage IB, II and IIIA. The question of whether it is better to apply chemotherapy prior to or after surgery can only be answered by the extensive randomised studies underway. The role of neoadjuvant chemotherapy in patients with NSCLC at clinical stage IIIA remains uncertain. The most rational approach to such patients appears to be neoadjuvant chemotherapy or chemotherapy with subsequent surgery.
