Purpose of the research is to establish which clinical and biopsy parameters could predict extra-capsular spread of prostate carcinoma for 2-10 ng/ml PSA values, in patients submitted to radical retropubic prostatectomy. Methodology: In the period of 30 months, 80 patients were treated with radical retro-pubic prostatectomy with bilateral pelvic lymphadenectomy, for whom clinical, biopsy, radiological and biochemical analysis were positive to organ limited tumor. Serum PSA, fpsa/tpsa, PSAD,values are evaluated, and other parameters as number of positive biopsies, percentage of positive biopsies, localization of positive biopsies, and perineural invasion and biopsy Gleason score. Results: from total number of 80 patients with 2-10 ng/ml PSA, 7 (9%) patients had extra-capsular spread of prostate carcinoma. Upon using multivariate regression analysis, following parameters were proved as significant predictors of extra-capsular spread: biopsy Gleason score, number of positive biopsy samples and invasion, while serum PSA, FPSA/TPSA ratio, PSAD, prostate age and volume have not shown as significant predictors for extra-capsular extension. Conclusion: Biopsy GS, perineural invasion and number of biopsy samples are statistically significant predictors of extra-capsular spread of prostate carcinoma for 2-10 ml PSA. Percentage of positive biopsies, tumor length in a sample and the localization of positive biopsies are on the borderline of statistical significance and as such should be taken into consideration.

    The dinoflagellates are a diverse lineage of microbial eukaryotes. Dinoflagellate monophyly and their position within the group Alveolata are well established. However, phylogenetic relationships between dinoflagellate orders remain unresolved. To date, only a limited number of dinoflagellate...
