Abstract:

Objective

To explore the relationship between BIM gene polymorphism and therapeutic efficacy in the advanced non-small cell lung cancer (NSCLC) with platinum drugs.

Methods

It was collected that 100 patients who were diagnosed with advanced NSCLC and received therapy with platinum drugs in oncology department of Chongqing Traditional Chinese Medicine Hospital from July 2012 to July 2015. The peripheral blood of patients was collected and genotype of BIM gene polymorphism was detected by polymerase chain reaction (PCR). Statistical analysis was performed by SPSS version 13.0.

Results

On the objective response rate(ORR), BIM gene with no polymorphism type was significantly better trend than polymorphism types in ORR(48.8% vs. 11.1%, χ2=8.598, P=0.003). The BIM gene polymorphism was the independent prognostic factors for progressin-free survival (PFS) by univariate Cox analysis. The median PFS in BIM gene with no polymorphism type were significantly longer than with polymorphism type(14.0 months vs. 10.0 months, P=0.001). However, BIM gene polymorphism did not have significant influence on adverse drug reaction (χ2=1.62, P>0.1).

Conclusions

The BIM gene polymorphism is the independent prognostic factor for PFS in patients of NSCLC, and detection of BIM gene polymorphism is important for prognostic evaluation of therapeutic efficacy in the advanced NSCLC with platinum drugs.
