Breast Invasive Carcinoma: Correlation between copy number variation genes and selected clinical features
Maintained by TCGA GDAC Team (Broad Institute/Dana-Farber Cancer Institute/Harvard Medical School)
Overview
Introduction

This pipeline computes the correlation between significant copy number variation (cnv) genes and selected clinical features.

Summary

Testing the association between copy number variation of 86 peak regions and 5 clinical features across 820 patients, 6 significant findings detected with Q value < 0.25.

  • Del Peak 2(1p21.2) cnvs correlated to 'AGE'.

  • Del Peak 16(6q27) cnvs correlated to 'AGE'.

  • Del Peak 22(9p23) cnvs correlated to 'Time to Death'.

  • Del Peak 39(16q11.2) cnvs correlated to 'AGE'.

  • Del Peak 40(16q23.1) cnvs correlated to 'AGE'.

  • Del Peak 41(16q24.3) cnvs correlated to 'AGE'.

Methods & Data
Input
  • Copy number data file = All Lesions File (all_lesions.conf_##.txt, where ## is the confidence level). The all lesions file is from GISTIC pipeline and summarizes the results from the GISTIC run. It contains data about the significant regions of amplification and deletion as well as which samples are amplified or deleted in each of these regions. The identified regions are listed down the first column, and the samples are listed across the first row, starting in column 10.

  • Clinical data file = BRCA.clin.merged.picked.txt

  • Number of patients = 820

  • Number of copy number variation regions = 86

  • Number of selected clinical features = 5

  • Exclude regions that fewer than K tumors have alterations, K = 3

Survival analysis

For survival clinical features, the Kaplan-Meier survival curves of tumors with and without gene cnvs were plotted and the statistical significance P values were estimated by logrank test (Bland and Altman 2004) using the 'survdiff' function in R

Student's t-test analysis

For continuous numerical clinical features, two-tailed Student's t test with unequal variance (Lehmann and Romano 2005) was applied to compare the clinical values between tumors with and without gene cnvs using 't.test' function in R

Fisher's exact test

For binary or multi-class clinical features (nominal or ordinal), two-tailed Fisher's exact tests (Fisher 1922) were used to estimate the P values using the 'fisher.test' function in R

Q value calculation

For multiple hypothesis correction, Q value is the False Discovery Rate (FDR) analogue of the P value (Benjamini and Hochberg 1995), defined as the minimum FDR at which the test may be called significant. We used the 'Benjamini and Hochberg' method of 'p.adjust' function in R to convert P values into Q values.
