Proper Treatment Selection May Improve Survival in Patients With Clinical Early-Stage Nonsmall Cell Lung Cancer

Patients with a CCI score of 3 or more have an increased risk of major postoperative complications. Nevertheless, patients with a CCI score of 3 or more show a better survival after surgery than after radiotherapy. For patients with significant comorbidity but with sufficient pulmonary reserve, surgery offers the best outcome. For patients with a high CCI score and insufficient pulmonary reserve or for those who refuse surgery curative, radiotherapy is a good alternative.
