While several genome-wide association studies （GWAS） of germline variants and whole-genome or whole-exome sequencing studies of somatic mutations in ESCC have been published, there is no comprehensive database publically available for this cancer. Here, we developed the Chinese Cancer Genomic Database-Esophageal Squamous Cell Carcinoma （CCGD-ESCC） database, which contains the associations of 69,593 single nucleotide polymorphisms （SNPs） with ESCC risk in 2022 cases and 2039 controls, survival time of 1006 ESCC patients （survival GWAS） and gene expression （expression quantitative trait loci,eQTL） in 94 ESCC patients. Moreover, this database also provides the associations between8833 somatic mutations and survival time in 675 ESCC patients. Our user-friendly database is a resource useful for biologists and oncologists not only in identifying the associations of genetic variants or somatic mutations with the development and progression of ESCC but also in studying the underlying mechanisms for tumorigenesis of the cancer. CCGD-ESCC is freely accessible at http：//db.cbi.pku.edu.cn/ccgd/ESCCdb.展开更多
