Abstract

Background

Patients with medically inoperable early-stage non-small cell lung cancer (NSCLC) may beneficiate of a hypofractionated radiation therapy in order to intensificate the treatment and to reduce the number of hospital access.

Methods

From 2007 to 2015, 27 patients with early-stage primary or limited loco-regional recurrent (T2a > 4 cm, T2b N0 or T1–2 N1M0) NSCLC were treated. All patients were medically inoperable or refused surgery and were treated with 60 Gy in 20 fractions, 5 times per week. Thirteen (48.1%) presented limited recurrence after surgery and 14 (51.9%) primary disease.

Results

Median follow-up was 34 months. Twelve patients achieved a CR (44.4%) and 8 a PR (29.6%) with a tumour response rate of 74%. Median overall survival (OS) and 2-year OS were 34 months and 63.0%, respectively. Median and 2-year loco-regional progression-free survival (LR-PFS) were 31 months and 51.4%, respectively. Survival outcomes were statistically favourable in patients with partial or complete response with respect to patients with stable or progressive disease, whereas stage (N0 vs N1) and primary or relapse/recurrent disease not. No cases of acute toxicity > grade 2 were observed. Seven patients (25.9%) presented grade 2 late toxicities.

Conclusion

Sixty Gy in 20 fractions is well tolerated and achieves good clinical outcomes in early primary or recurrent NSCLC patients. A greater number of patients and a longer follow-up are necessary to confirm the results obtained with our treatment.
