Background: This study aimed to evaluate short term clinical outcomes of accelerated hypofractionated radiotherapy (AHRT) regarding locoregional response (LRR), symptoms relief and acute toxicities in non-small cell lung cancer (NSCLC) patients. The radical treatment for inoperable NscLc is intolerable for some patients. An alternative RT regime should be considered for them. Materials and methods: Inoperable NscLc patients who could not tolerate radical treatment were treated with ahrT (45 Gy in 15 fractions over three weeks) by using the 3-dimensional conformal (RT) technique. The LRR was assessed by chest computed tomography (CT) performed before and 6 weeks after RT. Relief of symptoms such as cough, dyspnoea and chest pain was evaluated during RT and 6 and 12 weeks after RT, compared with the status before rT. Treatment-related acute toxicities such as dysphagia and radiation dermatitis were observed during and 6 and 12 weeks after RT. Results: Total 65 patients (seven patients of stage II and fifty-eight patients of stage III) were included. Partial response was seen in 70.8% of patients, and stable disease was seen in 29.2% while there was neither complete response nor progressive disease after RT. Statistically significant associations were found between tumour response vs. pre-treatment tumour size and tumour response vs. performance status of the patients. Ssatisfactory symptom relief was found after RT, but severe acute dysphagia and radiation dermatitis (more than grade 3) were not observed. Conclusion: satisfactory LRR, symptom relief and acute toxicities were achieved by this regime. Long term studies are recommended to evaluate late toxicities and survival outcome further.
