Group Iconsisted of primary, single, Ta grade, low grade, larger than 3 cm (> 3 cm) tumors; Group II consisted ofprimary, Ta grade, low grade, smaller than 3 cm (<3 cm), multiple tumors and Group III consisted of recurrenceof previous low-risk tumors. Three groups were compared in terms of clinical, pathological findings andrecurrence in follow-up.RESULTS: Mean age of patients was 65.73±12.21. Among them, 41 (41.4%) patients had recurrence in median48 (15-84) monthly follow-up. Recurrence rate in Group III (58.8%) was significantly higher than Group I(29.6%) and Group II (34.2%) (p = 0.039). The predicted recurrence-free survival (36.1 months) in Group IIIwas significantly lower than Group I (54.8 months) and Group II (61.2 months) (p=0.01 and p=0.003,respectively). In univariate analysis, the presence of previous recurrence, tumor size, number and CUETO score were reported as independent predictive factors for recurrence. In multivariate analysis, only the presence ofprevious recurrence was found to be significant.DISCUSSION and CONCLUSION: The subgroup analysis of intermediate-risk NMIBC may be helpful indetermining tumor treatment and follow-up protocols.We state that new tumor recurrences may be higher inintermediate-risk NMIBC with previous recurrence history.eninfo:eu-repo/semantics/openAccessTıbbi İnformatikGenel ve Dahili TıpTemel Sağlık HizmetleriOnkolojiSağlık Bilimleri ve HizmetleriArticle183117731469352
