Transcriptional levels of four prognostic markers in the peripheral blood of patients with gastric cancer.
| Marker | Above calibrator (%)* | Below calibrator (%)* | Undetectable (%) |
|---|---|---|---|
| Survivin | 69 (98.6) | 1 (1.4) | 0 (0.0) |
| CK19 | 68 (97.1) | 2 (2.9) | 0 (0.0) |
| CEA | 30 (42.9) | 21 (30.0) | 19 (27.1) |
| VEGF | 27 (38.6) | 43 (61.4) | 0 (0.0) |
* Gene expression levels were measured by quantitative real time PCR: using the relative quantification method, samples were classified as above or below the levels found in the calibrator (pooled peripheral blood samples from healthy donors).
