CitationCirculating tumor cells in patients with advanced urothelial carcinoma of the bladder: Association with tumor stage, lymph node metastases, FDG-PET findings, and survival. 2017, 35 (10):606.e9-606.e16 Urol. Oncol.
AbstractThere are currently no methods in clinical use that can detect early systemic dissemination of urothelial tumor cells.
To evaluate measurement of circulating tumor cells (CTCs) as a biomarker for disseminated disease in patients with advanced bladder cancer.
Between March 2013 and October 2015, 88 patients were prospectively included in the study: 78 were scheduled for radical cystectomy (RC) ± perioperative chemotherapy and 10 treated with palliative chemotherapy. The CellSearch CTC test was further assessed in this context by investigating expression of epithelial cell adhesion molecule (EpCAM) in primary tumors obtained at cystectomy from an independent cohort of 409 patients.
Presence of CTCs was tested for association with tumor stage, lymph node metastases, metastatic disease on [18 F]-fluorodeoxyglucose-positron emission tomography (FDG-PET), and cancer-specific and progression-free survival.
CTCs were detected in 17/88 patients (19%). In 61 patients who underwent FDG-PET-computed tomography (CT), a statistically significant association with presence of CTCs was found for radiological metastatic disease but not for normal PET-CT results (12/35 [34%] vs. 2/26 [8%], P = 0.014). After a median follow-up time of 16.5 months (95% CI: 9.6-21.4), presence of CTCs was associated with an increased risk of progression among patients treated with RC with or without perioperative chemotherapy (n = 75, P = 0.049). A multivariate analysis adjusted for clinical tumor stage, clinical lymph node status, and age showed that CTCs were an independent marker of progression (n = 75; hazard ratio = 2.78; 95% CI: 1.005-7.69; P = 0.049) but not of cancer-specific death (P = 0.596). In 409 cystectomised patients, more than 392 (96%) of the bladder tumors expressed EpCAM.
CTCs were present in 19% of patients with advanced urothelial tumors and were associated with metastatic disease on FDG-PET-CT and with increased risk of disease progression after RC. A significant portion of urothelial cancer cells do express EpCAM and can thus be identified using EpCAM-antigen-based CTC detection methods.
