The study revealed that CDCA5 is significantly overexpressed in multiple types of tumors and associated with poor survival, as well as correlated with immune cell infiltration, tumor mutation burden, and immune checkpoint expression.
Background: There have been several studies evaluating the prognostic significance of cell division cycle associated 5 (CDCA5). However, few reports analyzed the correlation between CDCA5 and prognosis of diverse cancers based on large clinical data. We thus comprehensively analyzed CDCA5 expression and clinical significance using The Cancer Genome Atlas (TCGA) data from 31 types of solid tumors.Methods: The expression profiles of CDCA5 were investigated across pan-cancer samples from the TCGA. Cox regression and Kaplan-Meier analysis was performed to determine CDCA5's prognostic value. CDCA5 expression was further validated by quantitative real-time PCR (qRT-PCR) and immunohistochemistry (IHC) in lung adenocarcinoma (LUAD).Results: We found that CDCA5 was significantly overexpressed in 22 types of tumors. Up-regulated CDCA5 was significantly related to poor survival in 13 types of tumors. Furthermore, CDCA5 expression was significantly associated with immune cell infiltration. Tumor mutation burden (TMB), microsatellite instability (MSI), and immune checkpoint expression were significantly correlated with CDCA5 expression. Additional analysis of IMvigor 210 cohort validated that patients with high level of CDCA5 had superior response to anti-PD-L1 therapy.Conclusion: Our findings suggested that CDCA5 could provide prognostic information in most types of cancers and contributed to tumor immune microenvironment.
