Triple-negative breast cancer (TNBC) is a heterogeneous disease. Recently, the development of a gene expression profile facilitated the re-classification of TNBC into six new subtypes, which show varied sensitivities to different therapies. In the era of precision medicine, precision therapy may be directed at various potentially actionable molecular mutations in different subtypes of TNBC.

Lung cancer is the leading cause of death worldwide. Non-small-cell lung cancer (NSCLC) accounts for most of these cases. T-cell immunoglobulin- and mucin-domain-containing molecule 3 (TIM-3) has been established as a negative regulatory molecule and plays a critical role in immune tolerance. Studies have shown that polymorphisms in TIM-3 gene can be associated with various diseases. The aim of this study was to investigate whether polymorphisms in the TIM-3 gene were associated with susceptibility to NSCLC. Three polymorphisms in TIM-3 gene (-1516G/T, -574G/T, and +4259T/G) were identified by polymerase chain reaction-restriction fragment length polymorphism in 432 NSCLC patients and 466 healthy controls. Results showed that frequencies of TIM-3 +4259TG genotype for cases and controls were 10.9 and 4.1 %, respectively; subjects carrying the +4259TG genotype had a 2.81-fold increased risk of NSCLC compared to the wild-type genotype (P < 0.0001). The TIM-3 -1516G/T and -574G/T polymorphisms did not show any correlation with NSCLC. In addition, when analyzing the survival time of NSCLC patients with TIM-3 +4259T/G polymorphism, cases with +4259TG genotype had significantly shorter survival time compared to the wild-type patients (15.2 months vs. 26.7 months, P = 0.007). These results suggested polymorphism in TIM-3 gene is associated with increased susceptibility to NSCLC and could be used as prognostic factor for this malignancy. © 2013 International Society of Oncology and BioMarkers (ISOBM).

Lung cancer is the leading cause of cancer mortality worldwide. Nonsmall cell lung cancer (NSCLC) accounts for most of these cases. Interleukin 4 (IL-4) is a typical pleiotropic T helper 2 cytokine and plays crucial roles in tumor immunology. IL-4 gene -590T/C polymorphism has been shown to be associated with different autoimmune diseases and cancers. The present study evaluated the correlation between this polymorphism and the susceptibility to NSCLC in the Chinese population. The IL-4 variant -590T/C was detected by polymerase chain reaction-restriction fragment length polymorphism in 1072 NSCLC cases and 1126 age-matched healthy controls. Data were analyzed using the Chi-square test. Results showed that frequencies of IL-4 -590 TC, CC genotype, and -590 C allele were significantly lower in patients with NSCLC than in healthy controls (odds ratio [OR]=0.77, 95% confidence interval [CI] 0.64-0.93, p=0.006; OR=0.54, 95% CI 0.38-0.76, p=0.0004; and OR=0.72, 95% CI 0.62-0.83, p=1.1×10 -5, respectively). Our data suggest that the -590T/C polymorphism of the IL-4 gene is associated with a decreased susceptibility to NSCLC. © Copyright 2012, Mary Ann Liebert, Inc.
