Urothelial carcinoma (UC) is a common type of malignant disease, but little is known about the diagnostic and prognostic markers of upper urinary tract urothelial cancer (UTUC) because of its rarity. To clarify the significance of ANXA10 in UTUC, we studied ANXA10 expression with immunohistochemistry (IHC). The expression of ANXA10 was analyzed in the upper and lower urinary tract of UC by IHC in combination with The Cancer Genome Atlas (TCGA) data analysis. The association between ANXA10 expression and representative cancer-related molecules was also evaluated. ANXA10 expression was weak in normal upper tract urothelium but was positive in 39/117 (33%) UTUCs. ANXA10 was more frequently positive in tumors with pure UC (36%, p < 0.05), papillary morphology (50%, p < 0.01), low grade (G1/2: 57%, p < 0.01), and pTa/is/1 stage (55%, p < 0.01) than in those with histological variants (0%), nodular morphology (9%), G3 (16%), and pT2/3/4 (13%), respectively. ANXA10-positive patients showed better cancer-specific survival and progression-free survival than ANXA10-negative patients (p < 0.05). IHC showed that ANXA10 positivity was detected more in cases with the low expression of TP53 (p < 0.01) and Ki-67 labeling index <20% (p < 0.01). In TCGA dataset of muscle-invasive bladder cancer, higher ANXA10 expression correlated with papillary morphology, lower grade/stage, luminal papillary subtype, wild-type TP53, and FGFR3 gene mutation. We revealed that ANXA10 expression was increased during carcinogenesis and was observed more frequently in papillary UC of lower grade and stage. However, its expression decreased as cancer progressed. Therefore, the ANXA10 expression in UTUC might be clinically useful for decision-making. © 2022 S. Karger AG, Basel.
