Cervical Squamous Cell Carcinoma: Correlation between copy number variation genes and molecular subtypes
(primary solid tumor cohort)

Maintained by TCGA GDAC Team (Broad Institute/MD Anderson Cancer Center/Harvard Medical School)

Overview

Introduction

This pipeline computes the correlation between significant copy number variation (cnv) genes and molecular subtypes.

Summary

Testing the association between copy number variation of 52 peak regions and 6 molecular subtypes across 126 patients, 15 significant findings detected with Q value < 0.25.

Amp Peak 4(2q32.3) cnvs correlated to 'CN_CNMF' and 'MRNASEQ_CNMF'.
Amp Peak 5(3q26.2) cnvs correlated to 'CN_CNMF'.
Amp Peak 6(3q28) cnvs correlated to 'CN_CNMF'.
Amp Peak 14(11q22.1) cnvs correlated to 'CN_CNMF'.
Del Peak 1(1p36.23) cnvs correlated to 'MIRSEQ_CHIERARCHICAL'.
Del Peak 5(3p11.1) cnvs correlated to 'CN_CNMF'.
Del Peak 6(4q22.1) cnvs correlated to 'CN_CNMF'.
Del Peak 7(4q35.2) cnvs correlated to 'CN_CNMF'.
Del Peak 14(10q26.3) cnvs correlated to 'CN_CNMF'.
Del Peak 19(15q15.1) cnvs correlated to 'CN_CNMF'.
Del Peak 21(16q23.1) cnvs correlated to 'MRNASEQ_CNMF', 'MRNASEQ_CHIERARCHICAL', and 'MIRSEQ_CHIERARCHICAL'.
Del Peak 24(19p13.3) cnvs correlated to 'MIRSEQ_CHIERARCHICAL'.

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.
Molecular subtype file = CESC-TP.transferedmergedcluster.txt
Number of patients = 126
Number of copy number variation regions = 52
Number of molecular subtypes = 6
Exclude regions that fewer than K tumors have alterations, K = 3

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.
