| الوصف: | e13517 Background: Glioblastoma (GB) is an aggressive tumor. Circulating Endothelial Cells (CECs) can be detected in peripheral blood and have been related to angiogenesis. CECs have an unclear prognostic value in patients with glioblastoma. The objective of this study was to quantify the presence and number of CECs in GB patients and determine its potential prognostic role. Methods: In this prospective, single center study, peripheral blood samples were obtained at the time of GB diagnosis. For the detection of CECs, 4 ml of blood was analyzed using the CellSearch system (Veridex). CEC blood samples were classified as CD146+, CD105+, CD45− and DAPI+. CEC detection was performed prior to surgery in a total of 26 patients and 22 patients with glioblastoma were included in the final analysis. We mesured progression free survival (PFS) and overall survival (OS). Results: Between 2014 and 2016, twenty two patients with histologically confirmed glioblastoma were studied. There were 14 males and 8 females with an average age of 63 years (range 42-81). A complete resection was achieved in 50% of cases, partial or subtotal resection in 31.8% and biopsy in 18%. The mean number of CECs was 59.3 cells/mL (range 0-954). Patients were classified into two groups depending on the number of CECs: group 1 had a CEC count below the mean and group 2 had a CEC count above the mean. A total of 17 patients (77.2%) were in group 1 and 5 patients (22.7%) were in group 2.The median OS was 14.4 months (range -0.36-33.36) for the entire study population. The median OS was 17.4 months (IC95% 11.47-23.37) for patients in group 1 and 8.12 months for patients in group 2 (IC 95% 4.38-11.85) p = 0.002. The median PFS was 8.94 m (IC95% 5.1-12.69) for group 1 and 3.95 for group 2 (IC 95% 2.91-4.98) p = 0.097. Conclusions: CECs can be detected in recently diagnosed GB patients. The present study demonstrates a possible prognostic value for CEC determination in GB cases at the time of diagnosis. |
