Evidence for surgical resections in oligometastatic lung cancer

With the advent of advanced technology in performing diagnostics for lung cancer, an incremental increase in the number of patients with oligometastatic disease is currently being managed with intent to cure. As treatment of selected types of patients with oligometastasis show favourable outcomes, the past notion of managing these patients palliatively is fast becoming extinct. Selection of patients based on established criterion together with surgical metastasectomy combined with multiple ablative techniques with or without systemic chemotherapy offers a reasonable rate of treatment success which provides basis for treating such patient population. As more evidence becomes available to suggest that the oligometastatic state of lung cancer does exist, and are potentially curable, a better understanding of the condition is necessary for clinicians, and surgeons to provide optimal care. In this review we present some of the clinical basis which may cause a paradigm shift in management of patients with oligometastatic lung disease.
