The prognostic value and potential subtypes of immune activity scores in three major urological cancers

Immune-based rather than cancer-based classification systems are becoming an important additional component for prognostic prediction. Herein, we investigate the status of tumor-immune interaction and prognostic value of immune activity scores in bladder urothelial carcinoma (BLCA), kidney renal clear cell carcinoma (KIRC), and prostate adenocarcinoma (PRAD) from The Cancer Genome Atlas dataset and tracking the tumor immunophenotype platform. Traditional clinicopathological parameters still are effective predictors for prognosis. Comparison of 23-set, seven-step immune activity scores, and its distribution between favorable and adverse outcome groups within each cancer type and among cancer types show that each cancer has a distinct tumor-immune pattern. Adjusted overall immune activity scores based on the binary logistic regression analysis show a great discrimination ability in the progression-free survival (p = .0056 in BLCA, p < .0001 in KIRC, and p < .0001 in PRAD). K-mean cluster method and principal component analysis were performed to explore the cancer subtype. The results reveal that certain immune activity scores pattern such as high nature killer (NK) cell, T cell, macrophage, T helper type 1 (Th1) cell, and dendritic cell recruiting scores in BLCA, low NK cell, CD8 T cell, macrophage, T cell, Th1 cell recruiting scores in KIRC have a favorable clinical outcome comparing to other subtypes. Also, It is remarkable that a relatively small subtype of patients has a poor clinical prognosis in PRAD and this subtype features high CD4 T cell, macrophage, T cell, and regulatory T cell recruiting scores.
