BACKGROUND/AIM: The addition of amifostine to chemoradiotherapy (CRT) or radiotherapy (RT) in advanced, inoperable NSCLC presents varying toxicity. The present study examined amifostine's effect on toxicity and efficacy of CRT or RT alone.
MATERIALS AND METHODS: Database searches yielded 16 eligible trials comprising of 1,057 patients. Results of randomised trials were pooled and used to estimate the overall effect.
RESULTS: Amifostine reduced the risk of >grade 2 acute oesophagitis by 26% [risk ratio (RR), 0.74; 95% confidence interval (CI)=0.65-0.86; p<0.0001] and the risk of acute pulmonary toxicity by 44% (RR, 0.56; 95%CI=0.41-0.75; p=0.0001). Risk of complete response was unchanged (RR, 1.64; 95%CI=0.99-2.73; p=0.06), partial response was unchanged (RR, 0.92; 95% CI=0.73-1.16; p=0.48). Statistical heterogeneity was high for toxicity but low for response.
CONCLUSION: Statistical heterogeneity of retrived results casts doubt over amifostine's efficacy in this setting, despite decreased acute oesophageal and pulmonary toxicity. Amifostine did not compromise treatment efficacy.
