Single-nucleotide polymorphisms of TGFβ1 and ATM associated with radiation-induced pneumonitis: a prospective cohort study of thoracic cancer patients in China.

ABSTRACT:

Background

We examined the effects of the rs1800469 and rs1800470 single nucleotide polymorphisms (SNPs) of the transforming growth factor-β1 (TGFβ1) gene and the rs189037 and rs373759 SNPs of the ataxia telangiectasia mutated (ATM) gene on the risk of radiation-induced pneumonitis (RP) in patients who underwent radiotherapy for various thoracic malignancies.

Methods

We determined the genotype and allele distributions of rs1800469 (C-509T), rs1800470 (C869T), rs189037 (A-111G), and rs373759 (126713 G>A) in 141 Han Chinese patients who underwent definitive thoracic radiotherapy (50 to 77 Gy, 5 days/wk) for lung cancer (small cell or non-small cell tumors, n = 97), esophageal squamous cell carcinoma (ESCC, n = 27), or mediastinal cancer (n = 17). Clinical variables were evalua
