Two hundred twenty-two cases were newly diagnosed, whereas 18 were recurrent tumours. Histopathological evaluation categorised the cases as non-neoplastic (33%, 13.7%), low-grade urothelial neoplasms (LGUNs) (94%, 39.2%), high-grade urothelial carcinoma (HGUCs) (110%, 45.8%) and other malignancies (3%, 1.3%).</p><p><strong>Results: </strong>TPS 2.0 categorised the cases as 14 (5.7%) non-diagnostic or ND/U, 99 (41.5%) NHGUC, 37 (15.4%) AUC, 24 (10%) SHGUC and 66 (27.5%) HGUC. TPS 1.0 had 14 (5.7%) ND/U, 72 (30%) NHGUC, 61 (24.5%) AUC, 3 (1.3%) LGUC, 24 (10%) SHGUC and 66 (27.5%) HGUC. FTRS classified them as 19 (7.5%) ND/UNS, 44 (18.3%) NEG, 88 (36.7%) INC and 89 (37.1%) POS. The ROHM for TPS 2.0 was 71.4% for ND/U, 12.1% for NHGUC, 29.7% for AUC, 79.2% for SHGUC and 89.4% for HGUC. TPS 1.0 showed a similar ROHM for ND/U, SHGUC and HGUC, whereas had 13.8% for NHGUC and 19.7% for AUCs. FTRS, had 78.9% for UNS, 6.8% for NEG, 35.2% for INC and 73.1% for POS. TPS demonstrated a sensitivity of 70.91% and specificity of 90.77% for identifying HGUC, whereas FTRS showed 59.09% sensitivity and 81.54% specificity.

The mean age of patients was 49 years, with a male-to-female ratio of 1.9:1, and 13 (56.5%) patients were HIV positive. Ten (43.5%) of 23 patients tested positive for Epstein-Barr virus (EBV).
