Overview
Introduction

This pipeline computes the correlation between significant arm-level copy number variations (cnvs) and selected clinical features.

Summary

Testing the association between copy number variation 63 arm-level events and 12 clinical features across 66 patients, 8 significant findings detected with Q value < 0.25.

  • 5p gain cnv correlated to 'PATHOLOGIC_STAGE'.

  • 5q gain cnv correlated to 'PATHOLOGIC_STAGE'.

  • 19p gain cnv correlated to 'PATHOLOGY_N_STAGE'.

  • 16p loss cnv correlated to 'Time to Death',  'PATHOLOGIC_STAGE', and 'PATHOLOGY_N_STAGE'.

  • 16q loss cnv correlated to 'Time to Death' and 'PATHOLOGY_N_STAGE'.

Methods & Data
Input
  • Copy number data file = broad_values_by_arm.txt from GISTIC pipeline

  • Processed Copy number data file = /xchip/cga/gdac-prod/tcga-gdac/jobResults/GDAC_Correlate_Genomic_Events_Preprocess/KICH-TP/19781646/transformed.cor.cli.txt

  • Clinical data file = /xchip/cga/gdac-prod/tcga-gdac/jobResults/Append_Data/KICH-TP/19775213/KICH-TP.merged_data.txt

  • Number of patients = 66

  • Number of significantly arm-level cnvs = 63

  • Number of selected clinical features = 12

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

Survival analysis

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