Abstract Perineural invasion (PNI), a particularly insidious form of tumor metastasis distinct from hematogenous or lymphatic spread, has the capacity to extend well beyond the primary tumor site, infiltrating distant regions devoid of lymphatic or vascular structures. PNI often heralds a decrease in patient survival rates and is recognized as an indicator of an unfavorable prognosis across a variety of cancers. Despite its clinical significance, the underlying molecular mechanisms of PNI remain elusive, complicating the development of specific and efficacious diagnostic and therapeutic strategies. In the realm of cancer research, non-coding RNAs (ncRNAs) have attracted considerable… More >

Abstract Introduction: Clinical variables with more accuracy to predict biologically insignificant prostate cancer are needed. We evaluated the combination of transrectal ultrasound-guided biopsy of the prostate (TRUSBx) pathologic and radiologic findings in their ability to predict the biologic potential of each prostate cancer.
Materials and methods: A total of 1043 consecutive patients who underwent TRUSBx were reviewed. Using pathologic criteria, patients with prostate cancer (n = 529) and those treated with radical prostatectomy (RP) (n = 147) were grouped as: “insignificant” (Gleason score ≤ 6, prostate-specific antigen (PSA) density ≤ 0.15 ng/mL, tumor in ≤ 50% of any… More >

Abstract Introduction: The clinical significance of perineural invasion (PNI) on prostate needle biopsy is controversial. The aim of this present study is to determine the role of PNI on prostate biopsy in predicting adverse findings at radical prostatectomy in a recent cohort of screen detected prostate cancer.
Materials and methods: We analyzed 470 patients diagnosed with prostate cancer from a prospectively maintained database at Princess Margaret Hospital. Out of the 470 patients diagnosed with prostate cancer, 139 underwent radical prostatectomy. Pathological specimens were examined, and perineural invasion was identified as carcinoma tracking along or around a nerve in… More >
