Homozygous A polymorphism of the complement C1qA276 correlates with prolonged overall survival in patients with diffuse large B cell lymphoma treated with R-CHOP.

ABSTRACT:

Background

The precise mechanism of action for rituximab (R) is not fully elucidated. Besides antibody-dependent cellular cytotoxicity (ADCC), complements may also play an important role in the clinical response to rituximab-based therapy in diffuse large B cell lymphoma (DLBCL). The purpose of this study was to explore the relationship between C1qA[276] polymorphism and the clinical response to standard frontline treatment with R-CHOP in DLBCL patients.

Methods

Genotyping for C1qA[276A/G] was done in 164 patients with DLBCL. 129 patients treated with R-CHOP as frontline therapy (R ≥ 4 cycles) were assessable for the efficacy.

Results

Patients with homozygous A were found to have a higher overall response rate than those with heterozygous or homozygous G alleles (97.3
