Purpose:
To report survival and control rates in patients with inoperable squamous cell carcinoma (SCC).
Methods And Materials:
Two hundred seventy-five patients with inoperable squamous cell carcinoma of the lung (Stages I-IIIB) who received radiotherapy alone or combined with chemotherapy given with curative intent at the University of Florida between 1963 and 2006 were retrospectively analyzed.
Results:
Overall survival (OS) at 5 years for Stages I, II, and III was 10%, 14%, and 7% (p = 0.0034); local-regional control at 5 years was 51%, 38%, and 29% (p = 0.0003); and freedom from metastases at 5 years was 81%, 60%, and 65% (p = 0.0689), respectively. Patients who received doses > or = 65 Gy had improved cause-specific survival (CSS), OS, and metastasis-free survival at 5 years compared with those who received doses < 65 Gy. Five-year regional control was significantly improved with twice-daily vs. once-daily treatment (37% vs. 14%, p = 0.02). Chemotherapy significantly improved 5-year regional control (36% for patients who received chemotherapy vs. 13% for those who did not; p = 0.01).
Conclusions:
Dose escalation, accelerated fractionation, and combined modality therapies improve outcomes in SCC of the lung. Our review of the literature highlights the different natural history for SCC vs. other non-small cell lung cancers and emphasizes the importance of tailoring treatment strategies to individual patients. At the University of Florida, we have begun treating unresectable Stage III patients with SCC of the lung using 69.6 Gy twice daily with concurrent chemotherapy.
