Patterns of Local-Regional Failure in Completely Resected Stage IIIa (N2) Non-Small Cell Lung Cancer Patients: Implications for Postoperative Radiation Therapy Target Volumes

Abstract

There is a need to evaluate the mediastinal nodal involvement risk based on primary location of tumors and standardize the clinical target volume (CTV) for postoperative radiation therapy (PORT) in completely resected stage N2 patients. Thus we reviewed patterns of locoregional failure for completely resected stage IIIa (N2) patients and examined whether they were consistent with the proposed PORT fields.
