There is sparse literature regarding extended survival of patients treated for T4 and/or N3 lung cancers. We present the results of a case series from our radiotherapeutic experience over the last 12 years to provide additional information. Out of 189 individuals diagnosed with lung cancer between 1997 and 2008, seven treated patients who survived five years or longer were identified. The median age was 56 years. More than half of the subjects were symptomatic at the time of hospitalization, possessed voluminous, non-small-cell histologic type malignant neoplasms, and received chemotherapy also. All individuals responded to treatment, and their survival ranged from 60 to 169 months. Our observed long-term survivors seem to justify the continued practice of modern standards of care in patients with lung cancer.
