A. Mean ARSB H-scores were calculated for stroma,
epithelium, and combined stroma and epithelium for 22 pairs of prostate cancer
cases that differed by recurrence vs. non-recurrence at 4 or more years of
followup. Recurrences had lower mean ARSB H-scores for stroma (0.10 ±
0.08 vs. 0.19 ± 0.09), epithelium (0.48 ± 0.32 vs. 0.86
± 0.24) and combined stroma and epithelium (0.28 ± 0.26 vs. 0.62
± 0.28) and differences were highly significant (p=0.0021, p=0.0003,
p=0.0006, respectively, paired t-test, two-tailed).
B. Scattergram shows the ARSB H-scores in the 22 pairs of
prostate cancer cases for epithelium and stroma combined. H-scores less than
0.25 accurately predicted recurrence, and H-scores over 0.70 were associated
with non-recurrence in 8 of 9 cases. Green squares indicate non-recurrence, and
red diamonds indicate recurrence.
