Comparison Between Stereotactic and Conventional Radiotherapy for Solitary Lung Tumor After Resection of Lung Cancer
We retrospectively compared stereotactic body radiotherapy (SBRT) with conventionally fractionated radiotherapy (CFRT) for a solitary lung tumor after resection of a non-small cell lung cancer (NSCLC), due to a lack of data concerning whether SBRT or CFRT is more effective in this setting.

Summary: | We retrospectively compared stereotactic body radiotherapy (SBRT) with conventionally fractionated radiotherapy (CFRT) for a solitary lung tumor after resection of a non-small cell lung cancer (NSCLC), due to a lack of data concerning whether SBRT or CFRT is more effective in this setting.
SBRT using 48 Gy in 4 fractions was administered to 15 patients with a peripheral tumor (SBRT group). CFRT using 66-70 Gy in 33-35 fractions was administered to 11 patients with a central tumor (CFRT group).
The median follow-up time was 32 months (range: 9-79 months). The 3-year overall survival rates in SBRT and CFRT groups were 81% and 40%, respectively (p=0.008). The 3-year local control rates in SBRT and CFRT groups were 83% and 35%, respectively (p=0.035). Regarding toxicities, no significant differences were found between the two groups.
Compared to CFRT, SBRT may be more effective in solitary-lung-tumor patients after the complete resection of an NSCLC as with inoperable-stage I-NSCLC patients. |
