ABSTRACT
Thoracic irradiation historically plays a strong role in the management of non-small
cell lung cancer (NSCLC). Though surgery is the mainstay of early-stage (I and II)
disease, adjuvant radiation therapy confers better local control than surgery alone
in advanced disease (III). Combining chemotherapy with radiation can help decrease
systemic tumor burden and confer an overall survival advantage. Patients with medically
inoperable early-stage disease can be treated with radiation alone, and bulky advanced-stage
tumors can be treated definitively with platinum-based concurrent chemotherapy and
radiation. The success of chemotherapy with radiation together has led to trials of
induction treatment for borderline surgical candidates, allowing for downstaging and
more complete resection. Local control remains a challenge, and dose escalation as
well as more conformal treatment planning studies need to be explored to overcome
this problem.
