[Evaluation of efficacy of surgery for early lung cancer]

The efficacy of surgery for early lung cancer is generally high. Size of tumor remains a most significant factor of prognosis, alongside histological pattern, cell differentiation and extent of intervention, both in non-small- and small-cell lung cancer. Biological virulence of tumors measuring up to 2 cm and 2.1-3 cm varies, thus correlating with prognosis. Small-cell pattern, non-cell differentiation degree, extent of intervention, tumor size, history duration and gender are the most significant factors of prognosis in surgery for early lung cancer.
