INTRODUCTION: The purpose of this study was to evaluate the impact of circulating tumor cells (CTCs) as a prognostic marker in patients with high-risk non-muscle-invasive bladder cancer (NMIBC) and assess the efficacy and reliability of 2 different CTC isolation methods. MATERIALS AND METHODS: Globally, 155 patients with a pathologically confirmed diagnosis of high-risk NMIBC were included (pT1G3 with or without carcinoma in situ) and underwent transurethral resection of bladder tumor (TURB) after a blood withdrawal for CTC evaluation. A total of 101 patients (Group A) had their samples analyzed with the CellSearch automated system, and 54 (Group B) had their samples analyzed with the CELLection Dynabeads manual system. RESULTS: Patients were followed for 28 months, and during this interval, there were a total of 65 (41.9%) recurrences, 27 (17.4%) disease progressions, and 9 (5.8%) lymph node and/or bone metastasis. In our CTC analysis, there were 20 (19.8%) positive patients in Group A and 24 in Group B (44.4%). In our analysis, we found a strong correlation between CTC presence and time to first recurrence; in Group A, we observed an incidence of recurrence in 75% of CTC-positive patients and in Group B of 83% of CTC-positive patients. The time to progression was also strongly correlated with CTCs: 65% and 29%, respectively, of those patients who progressed in those with CTCs in Group A and B. CONCLUSION: The study demonstrates the potential role of CTCs as a prognostic marker for risk stratification in patients with NMIBC, to predict both recurrence and progression.
