LIMCH1 as a New Potential Metastasis Predictor in Breast Cancer.

ABSTRACT:

Background and objective

High LIMCH1 expression in lung and renal cancer is determined as a favorable prognostic factor. However, prognostic value of LIMCH1 expression in breast cancer has not been studied yet. Therefore, this study was performed to determine the prognostic value of LIMCH1 expression in breast cancer patients.

Methods

This retrospective study included 89 patients with invasive breast carcinoma of no special type. These patients referred to Cancer Research Institute of Tomsk National Research Medical Center from 2007 to 2018. LIMCH1 protein expression in tumor cells was detected by immunohistochemical analysis in this study. Statistical analysis was done to investigate the possible relationship between LIMCH1 protein expression and clinicopathological parameters, risk of metastasis, distant metastasis free survival, and overall survival.

Results

IHC analysis of breast cancer tissue samples revealed that LIMHC1 protein expression was found in 29.2% (26/89) of the cases. Lymph node and distant metastases were more frequent in patients with LIMCH1 protein expression. LIMCH1 protein expression increased the risk of distant metastasis based on our findings. LIMCH1 protein affected metastatic-free survival regardless of the T, as well as other clinical and pathological parameters (p=0.0146, HR=3.2058 (1.26; 8.17)). Moreover, LIMCH1 protein expression was associated with worse overall survival (p=0.0071, HR=2.73 (1.28; 5.85)) in our breast cancer patients.

Conclusion

LIMCH1 protein expression was associate with metastases development, providing prognostic stratification. In breast cancer, LIMCH1 protein expression was found as an unfavorable prognostic factor of distant metastasis-free survival based on our findings.

Project description:BackgroundTriple-negative breast cancer is a subtype of breast cancer with aggressive tumor behavior and distinct disease etiology. Due to the lack of an effective targeted medicine, treatment options for triple-negative breast cancer are few and recurrence rates are high. Although various multi-gene prognostic markers have been proposed for the prediction of breast cancer outcome, most of them were proven clinically useful only for estrogen receptor-positive breast cancers. Reliable identification of triple-negative patients with a favorable prognosis is not yet possible.Methodology/principal findingsClinicopathological information and microarray data from 157 invasive breast carcinomas were collected at National Taiwan University Hospital from 1995 to 2008. Gene expression data of 51 triple-negative and 106 luminal breast cancers were generated by oligonucleotide microarrays. Hierarchical clustering analysis revealed that the majority (94%) of triple-negative breast cancers were tightly clustered together carrying strong basal-like characteristics. A 45-gene prognostic signature giving 98% predictive accuracy in distant recurrence of our triple-negative patients was determined using the receiver operating characteristic analysis and leave-one-out cross validation. External validation of the prognostic signature in an independent microarray dataset of 59 early-stage triple-negative patients also obtained statistical significance (hazard ratio 2.29, 95% confidence interval (CI) 1.04-5.06, Cox P=0.04), outperforming five other published breast cancer prognostic signatures. The 45-gene signature identified in this study revealed that TGF-? signaling of immune/inflammatory regulation may play an important role in distant metastatic invasion of triple-negative breast cancer.Conclusions/significanceGene expression data and recurrence information of triple-negative breast cancer were collected and analyzed in this study. A novel set of 45-gene signature was found to be statistically predictive in disease recurrence of triple-negative breast cancer. The 45-gene signature, if further validated, may be a clinically useful tool in risk assessment of distant recurrence for early-stage triple-negative patients.
