Objective: The study aims to assess the both individual behavior and correlations of stromal fibrillary component (SFC) and vascular density (VD) in relation with Srigley architectural patterns of prostate carcinoma. Materials and Methods: Digital images of prostate adenocarcinoma labeled following both Gleason and Srigley systems were acquired with x20 objective from two serial sections, 340 from the section stained using Gomori technique for SFC assessment and another corresponding 340 from the section immunomarked with anti-CD34 antibody for assessment of VD. The SFC amount and VD were determined and compared. Srigley patterns were divided in two redefined behavioral groups: solid group (Srigley I, Srigley III, Srigley IV) and necrotizing group (Srigley II with subdivisions: Gleason 3A, 3C and 5A). Results: SFC mean values had an ascending trend in both solid and necrotizing groups. VD mean values had an ascending trend in solid group but a descending trend in necrotizing group towards Gleason 5A pattern. SFC and VD values had a direct, ascending correlation for all determinations (p=0.0006), but also for solid (p=0.005) and necrotizing (p=0.026) groups. The two stromal elements had different behaviors both individually and in their correlation that seem to be related with their interaction with different tumor cellular populations. Conclusions: Our results could plead for the hypothesis that the different subtypes of tumor architecture represent steps of a continuous process from well-differentiated status to poorly or undifferentiated status but who is accomplished by two different tumor cells populations with different distinct behavior in their relationship with the stromal microenvironment.
