Summary of TCGA data analyzed by tumor type.

*LAML: Acute myeloid leukemia; BRCA: Breast invasive cancer; GBM: Glioblastoma multiforme; KIRC: Kidney renal clear cell carcinoma; KIRP: Kidney renal papillary cell carcinoma; LUSC: Lung squamous cell carcinoma; LUAD: Lung adenocarcinoma; LIHC: Liver hepatocellular carcinoma; OV: Ovarian serous cystadenocarcinoma; STAD: Stomach adenocarcinoma; ND = Not determined.†Samples – C: Cancer samples; Samples – N: Normal samples; Int. Reads – C: Reads supporting integration from cancer samples; Int. Reads – N: Reads supporting integration from normal samples; Bac. Reads – N: Read pairs mapping to bacteria in cancer samples; Bac Reads – N: Read pairs mapping to bacteria in normal samples; Tot. Pairs – C: Total read pairs in cancer samples; Tot. Pairs – N: Total read pairs in normal samples; Int. Freq – C: Integration frequency in cancer samples; Int. Freq. – N: Integration frequency in normal samples.‡C/B is the integration rate in cancer samples divided by the integration rate in normal samples. When a normal was not available (LAML, KIRC, KIRP, LUSC, LUAD, STAD) the value from BRCA was used. BRCA was chosen because it is RNA sequencing as are the samples being examined that lack normal samples.
