Serum monocyte fraction of white blood cells is increased in patients with high Gleason score prostate cancer.

ABSTRACT: Systemic inflammation and immune responses are reported to be associated with progressive prostate cancer. In this study, we explored which among the fractions of white blood cell (WBC) and C-reactive protein (CRP) level were associated with high Gleason score prostate cancer. Prostate needle biopsy was performed in 966 men with suspicion of prostate cancer. We assessed age, serum prostate-specific antigen (PSA), prostate volume, WBC count, fractions of WBCs (neutrophils, lymphocytes, monocytes, basophils, and eosinophils), and CRP level before biopsy for associations with biopsy findings. Among all men, 553 (57.2%) were positive for prostate cancer including 421 with high Gleason score cancer (Gleason score ?7). Age, PSA, PSA density (PSAD), serum monocyte fraction of WBC, monocyte-to-lymphocyte ratio (MLR), and CRP were significantly associated with high Gleason score cancer (p<0.01). Multivariate analysis showed that age, PSA, PSAD, and serum monocyte fraction were significantly associated with high Gleason score prostate cancer (p <0.01). In 571 patients with PSA of <10 ng/ml, age, PSA, PSAD, serum WBC count, neutrophil fraction, monocyte fraction, and MLR were significantly associated with high Gleason score prostate cancer (p<0.05). Multivariate analysis showed that age, PSAD, and serum monocyte fraction were significantly associated with high Gleason score prostate cancer (p<0.01). The monocyte fraction of WBCs was increased in patients with high Gleason score prostate cancer, suggesting an interaction of monocytes with the progression of prostate cancer.

Project description:BackgroundProstate tumor volume predicts biochemical recurrence, metastases, and tumor proliferation. A recent study showed that prostate tumor eccentricity (elongation or roundness) correlated with Gleason score. No studies examined the relationship among the prostate tumor's shape, volume, and potential aggressiveness.MethodsOf the 26 patients that were analyzed, 18 had volumes >1 cc for the histology-based study, and 25 took up contrast material for the MRI portion of this study. This retrospective study quantitatively compared tumor eccentricity and volume measurements from pathology assessment sectioned wholemount prostates and multi-parametric MRI to Gleason scores. Multi-parametric MRI (T1, T2, diffusion, dynamic contrast-enhanced images) were resized, translated, and stitched to form spatially registered multi-parametric cubes. Multi-parametric signatures that characterize prostate tumors were inserted into a target detection algorithm (Adaptive Cosine Estimator, ACE). Various detection thresholds were applied to discriminate tumor from normal tissue. Pixel-based blobbing, and labeling were applied to digitized pathology slides and threshold ACE images. Tumor volumes were measured by counting voxels within the blob. Eccentricity calculation used moments of inertia from the blobs.ResultsFrom wholemount prostatectomy slides, fitting two sets of independent variables, prostate tumor eccentricity (largest blob eccentricity, weighted eccentricity, filtered weighted eccentricity) and tumor volume (largest blob volume, average blob volume, filtered average blob volume) to Gleason score in a multivariate analysis, yields correlation coefficient R=0.798 to 0.879 with P<0.01. The eccentricity t-statistic exceeded the volume t-statistic. Fitting histology-based total prostate tumor volume against Gleason score yields R=0.498, P=0.0098. From multi-parametric MRI, the correlation coefficient R between the Gleason score and the largest blob eccentricity for varying thresholds (0.30 to 0.55) ranged from -0.51 to -0.672 (P<0.01). For varying thresholds (0.60 to 0.80) for MRI detection, the R between the largest blob volume eccentricity against the Gleason score ranged from 0.46 to 0.50 (P<0.03). Combining tumor eccentricity and tumor volume in multivariate analysis failed to increase Gleason score prediction.ConclusionsProstate tumor eccentricity, determined by histology or MRI, more accurately predicted Gleason score than prostate tumor volume. Combining tumor eccentricity with volume from histology-based analysis enhanced Gleason score prediction, unlike MRI.
