Abstract (sommario):

Signet ring cell prostatic intraepithelial neoplasia is a rare speculated variant of high-grade prostatic intraepithelial neoplasia (HGPIN). Here, we present a free-standing and isolated signet ring cell HGPIN that was not associated with invasive carcinoma on needle biopsy and demonstrated the existence of this type of HGPIN variant. The differentiation between HGPIN and intraductal carcinoma of prostate is also discussed.

Abstract (sommario):

Abstract Context.—Recently, prostatic atrophy associated with chronic inflammation has been linked to carcinoma either directly or indirectly by first developing into high-grade prostatic intraepithelial neoplasia. Objective.—The purpose of our study was to test this hypothesis in autopsies. Design.—A step section method was used to cut the posterior lobe in coronal planes at intervals of 0.3 to 0.5 cm in 100 consecutive autopsies of men older than 40 years. Prostatic atrophy was classified as simple, hyperplastic (or postatrophic hyperplasia), and sclerotic and was analyzed for the presence of chronic inflammation. Prostatic atrophy without (group A) and with inflammation (group B) was correlated with the following variables: age, race, histologic (incidental) carcinoma, high-grade prostatic intraepithelial neoplasia, and extent of both these lesions. Results.—Of the 100 prostates examined, 12%, 22% and 66%, respectively, had no atrophy, atrophy without inflammation (group A), and atrophy with inflammation (group B). There was no statistically significant difference between groups A and B for age (P = .55), race (P = .89), presence of histologic (incidental) carcinoma (P = .89), extensive carcinoma (P = .43), presence of high-grade prostatic intraepithelial neoplasia (P = .65), extensive high-grade intraepithelial neoplasia (P = .30), or subtypes of prostatic atrophy. Neither a topographical relation nor a morphologic transition was seen between prostatic atrophy and histologic carcinoma or high-grade intraepithelial neoplasia. Sclerotic atrophy either alone or combined with other subtypes was more frequent in the group with inflammation. A striking morphologic finding was a topographical relation of focal inflammation with sclerotic atrophy in areas with erosion of the epithelium. Conclusions.—Inflammatory prostatic atrophy does not appear to be associated with histologic (incidental) carcinoma or high-grade intraepithelial neoplasia. One possible cause of inflammatory infiltrate associated with prostatic atrophy may be the extravasated prostatic secretions, which were noted in areas of eroded epithelium, a common finding in the sclerotic type of prostatic atrophy.

Abstract (sommario):

Abstract Context.—Annexin II is a calcium-dependent phospholipid-binding protein that plays a role in many cellular functions, including apoptosis, signal transduction, and cellular motility. The protein is strongly expressed in normal prostatic epithelial glands, but its expression in benign prostatic lesions has not been reported. Although commonly underexpressed in prostate cancer, the association of reduced expression with pathologic grade and stage is unknown. Objective.—To compare annexin II expression in benign prostatic lesions with expression in high-grade prostatic intraepithelial neoplasia and prostate cancer, as well as to correlate expression levels with pathologic grade and stage. Design.—A semi-quantitative assessment of annexin II expression was performed in radical prostatectomy specimens from 74 patients and prostate needle core biopsy specimens from 13 patients. Foci with normal prostatic glands, atrophic glands, basal cell hyperplasia, high-grade prostatic intraepithelial neoplasia, and prostatic adenocarcinoma were evaluated. Results.—Annexin II expression was present in more than 50% of glands in most (>85%) samples of benign prostatic epithelium, atrophic glands, and basal cell hyperplasia. In high-grade prostatic intraepithelial neoplasia, annexin II staining was markedly reduced in epithelial cells but not in basal cells. Annexin II was absent or focally present in moderately differentiated adenocarcinoma but was retained in poorly differentiated adenocarcinomas. Conclusions.—Reduced annexin II expression may be a useful diagnostic biomarker to help identify small foci of moderately differentiated adenocarcinoma on needle core biopsy specimens since it is consistently expressed in benign prostatic glands. Re-expression of annexin II in poorly differentiated adenocarcinoma may provide prognostic information.

Abstract (sommario):

Abstract Context.—There have been 2 putative prostatic cancer precursors, prostatic intraepithelial neoplasia (PIN) and atypical adenomatous hyperplasia (adenosis), but PIN remains as a well-known precancerous condition. Objective.—To describe recent advances in knowledge of PIN and to better define the diagnostic criteria and differential diagnosis of PIN. Data Sources.—Review of the pertinent literature and our experience. Conclusions.—The presence of ductal/acinar epithelial changes including nuclear enlargement, prominent nucleoli, chromatin alterations, and luminal complexity is an easy way to identify the disorder. Four main patterns of high-grade PIN (HGPIN) have been described: tufting, micropapillary, cribriform, and flat. In addition, variants of HGPIN have also been described. Both HGPIN and prostatic carcinoma share an increased incidence and severity with advancing age and with high rates of occurrence in the peripheral zone of the prostate. Furthermore, HGPIN and prostate cancer share genetic and molecular markers as well, with PIN representing an intermediate stage between benign epithelium and invasive carcinoma. The clinical significance of HGPIN is that it identifies patients at risk for prostatic carcinoma. With the increased use of extended biopsy protocols, clinicians are more likely to identify HGPIN and less likely to miss concurrent carcinoma.

Abstract (sommario):

Prostate intraepithelial neoplasia is described as a precursor lesion to prostatic adenocarcinoma. High-grade prostate intraepithelial neoplasia (HGPIN) is classified as both grade 2 and 3 prostate intraepithelial neoplasia due to inconsistency between pathologists’ findings. In our study, we assessed the interobserver variability in the diagnosis of HGPIN among genitourinary and nongenitourinary pathologists. All cases with prostate adenocarcinoma diagnosis on needle core biopsy, radical prostatectomy, and transurethral resection of prostate (TURP) between the years 2005 and 2014 were included. In total, 191 prostate cancer cases were included: 109 needle core biopsies, 45 radical prostatectomies, and 37 TURP. All were independently reviewed by 2 urologic pathologists for the presence of HGPIN. High-grade prostate intraepithelial neoplasia was diagnosed in 65 cases (34%), among which the lesion was recognized by the reporting pathologists in 36 (55%) of the cases and was missed in 29 (45%) of the cases with a κ coefficient of 0.53. There was a moderate interobserver agreement in the diagnosis of HGPIN. Consultation with genitourinary pathologist can improve HGPIN diagnosis.

Abstract (sommario):

Context.—Fusions of androgen-regulated genes and v-ets erythroblastosis virus E26 oncogene homolog (avian) (ERG) occur in approximately 50% of prostate cancers, encoding a truncated ERG product. In prostatectomy specimens, ERG rearrangements are greater than 99% specific for prostate cancer or high-grade prostatic intraepithelial neoplasia adjacent to ERG-rearranged prostate cancer by fluorescence in situ hybridization and immunohistochemistry. Objective.—To evaluate ERG staining by immunohistochemistry on needle biopsies, including diagnostically challenging cases. Design.—Biopsies from a retrospective cohort (n = 111) enriched in cores requiring diagnostic immunohistochemistry and a prospective cohort from all cases during 3 months (n = 311) were stained with an anti-ERG antibody (clone EPR3864). Results.—Among evaluable cores (n = 418), ERG staining was confined to cancerous epithelium (71 of 160 cores; 44%), high-grade prostatic intraepithelial neoplasia (12 of 68 cores; 18%), and atypical foci (3 of 28 cores; 11%), with staining in only 2 of 162 cores (1%) diagnosed as benign. The ERG was expressed in about 5 morphologically benign glands across 418 cores and was uniformly expressed by all cancerous glands in 70 of 71 cores (99%). Conclusions.—ERG staining is more prostate cancer–specific than α-methylacyl-coenzyme A racemase, and staining in an atypical focus supports a diagnosis of cancer if high-grade prostatic intraepithelial neoplasia can be excluded. Thus, ERG staining shows utility in diagnostically challenging biopsies and may be useful in molecularly subtyping prostate cancer and in stratifying isolated high-grade prostatic intraepithelial neoplasia by risk of subsequent cancer.

Abstract (sommario):

45 Background: High-grade prostatic intraepithelial neoplasia (HGPIN) is widely believed to be a precursor of prostate cancer (PCa). However, little is known about the expression of miRNAs variations in HGPIN compared to normal tissues and PCa. Methods: The expression data of 1054 miRNAs from TCGA were applied to identify relevant miRNAs associated with tumor progression (i.e., miR-98-5p, miR-183-5p, 345-5p, miR-143 miR-210-3p and miR-378-3p). miRNA were isolated by miRNeasy FFPE kit (Qiagen, Hilden, Germany) from paraffin-embedded tissues (FFPE) of prostate specimens with PCa, HGPIN and normal tissues. Early-stage PCa was defined as PCa with pT2 tumor stage, Gleason score <=7a (3+4) and PSA level <10 ng/ml. Quantitative miRNA expression data were acquired and analyzed using a real-time TaqMan-based PCR with the ABI Prism 7900HT (Life Technologies, Darmstadt, Germany). ANOVA analysis were performed to evaluate the expression of miRNAs between HGPIN, Normal and PCa tissues. All statistical analysis was performed using SPSS (IBM, Armonk, USA). P values were adjusted using the false discovery rate for multiple comparisons. The small nuclear U6 RNA was used as an endogenous control. Results: The expression of miR-143-3p, miR-210-3p and miR-345-5p and miR-98-5-p were varied between normal tissue, HGPIN and early-stage PCa. Interestingly, decrease in expression of miR-143.-3p, miR-98-5p and miR-210-3p was associated with tumor development (Normal tissues > HGPIN > early-stage PCa) (FDR<0.001). Furthermore, overexpression of miR-345-5p was observed in normal tissues compared to HGPIN and early-stage PCa, which both showed similar expression level of miR-345-5p. No significant differences in expression of miR-375, miR-183-5p and miR-378-3p were observed between HGPIN and PCa. These miRNAs were interacted with genes related to HIF-1 signaling pathway, p53 signaling pathway, androgen receptor signaling pathway, intrinsic apoptotic signaling pathway, RNA transcription, homologous recombination and non-homologous end-joining. Conclusions: HGPIN shows an altered expression of miRNAs interact with genes related to hypoxia, androgen receptor signaling pathway, cell cycle and epigenetic regulation.

Abstract (sommario):

Abstract Background.—Elastosis of the prostate may be seen on needle biopsy and radical prostatectomy specimens, but its significance is unknown. Prostatic atrophy (or postatrophic hyperplasia) is one of the most frequent mimics of prostatic adenocarcinoma. Objective.—To observe the frequent occurrence of elastosis of the prostate stroma in areas of postatrophic hyperplasia. Design.—A step-section method was used to cut the posterior lobe (or peripheral zone) in coronal planes at intervals of 0.3 to 0.5 cm in 100 consecutive autopsy specimens of men older than 40 years. Elastosis was detected because of a basophilic tinge of the stroma on hematoxylin-eosin stain and confirmed using elastic fiber stains. Presence of elastosis correlated with the following variables: age, prostatic atrophy (simple, hyperplastic, or sclerotic), local arteriosclerosis, histologic carcinoma, high-grade prostatic intraepithelial neoplasia, benign or malignant nephrosclerosis, generalized atherosclerosis, nodular prostatic hyperplasia, and acute inflammation. For statistics, a stepwise linear regression method adjusted for age was used. Results and Conclusions.—Elastosis was found in 65 of the prostates examined and was significantly more frequent with increasing age (P < .001), prostatic atrophy (P < .001), and local arteriosclerosis (P < .02). There was no significant relation to histologic carcinoma, high-grade prostatic intraepithelial neoplasia, benign or malignant nephrosclerosis, generalized atherosclerosis, nodular prostatic hyperplasia, and acute inflammation. The correlation with local arteriosclerosis favors a possible role of ischemia to its etiopathogenesis. The absence of correlation to neoplastic and preneoplastic lesions and the striking spatial relationship of elastosis to prostatic atrophy (or postatrophic hyperplasia) add a new microscopic feature for the diagnosis of this latter lesion, helping in the differential diagnosis with prostate adenocarcinoma.

Abstract (sommario):

Background/Aim. Prostatic intraepithelial high grade neoplasia (PINHG) is accepted as preneoplastic lesion in prostatic carcinoma. One of the fundamental events in early oncogenesis is the disruption of proliferative activity. One of the numerous regulatory proteins is Ki-67 expressed in all proliferating cells. Index Ki-67 is considered to have prognostic significance. The aim of the study was to compare the level of proliferation in hyperplastic epithelium, prostatic carcinoma (Gleason score > 6) and PINHG. Methods. Micromorphological examination was done in 85 patients. Pathohistological analysis was performed on standard histologic specimens with the estimation of Gleason score and the presence of PINHG in its surroundings. Nuclear proliferative activity was analyzed immunohistochemically in 19 cases, using a monoclonal anti-Ki-67 antibody. Results. PINHG was found in prostatic carcinoma surrounding in 30% of the patients. In hyperplastic epithelia Ki-67 proliferative activity was 1,08, in PINHG 2,25 (p < 0,05), while in prostatic cancer, Ki-67 index was 17,64. Proliferative activity in prostatic carcinoma was significantly higher than in PINHG (p < 0,001) and hyperplasia (p < 0,001). Conclusion. This study confirmed that high grade PIN lesion predominately appears in the surrounding of poor or moderately differentiated prostate carcinoma, and that it represents progressive disorder of proliferation in preneoplastic and neoplastic prostatic epithelium. .

Abstract (sommario):

Introduction. Benign prostatic hyperplasia (BPH) is a neoplasm and clinically occurred by progressive enlargement of the prostate. However, prostate neoplasm can also be malignant, which is come out from high-grade prostatic intraepithelial neoplasia (PIN). It is a proven precancerous condition. Purpose. Тo evaluate the data published on September and October 2020 on the prevalence, pathogenesis of BPH and PIN and methods of their treatment. Materials and methods. The search results in scientific databases PubMed, MEDLINE, Embase were analyzed for the queries «BPH», «PIN», «epidemiology of BPH», «pathogenesis», «treatment of PIN». Results. BPH is a very common disease in the elderly population. The pathogenesis of BPH includes age, genetics or hormones disorders, growth factors, inflammation, and lifestyle factors. PIN is the only common precursor of prostatic cancer. The main treatment methods are 5α-reductase inhibitors, phosphodiesterase-5 inhibitors, and surgical methods. In addition, plant active molecules are also widely used in the treatment of BPH and PIN. Conclusions. While 5α-reductase and phosphodiesterase-5 inhibitors treatment, as well as surgical methods have a lot of adverse events and complications, a unique herbal complex Gardaprost was developed, which suppresses hyperplasia of prostate. Curcumin, genistein and epigalocatechin-3- gallate, which are part of the preparation, form a safe agent aimed at combating the growth of the prostate gland in BPH, and also has a significant effect in the prevention of exacerbations of chronic prostatitis and malignancy in patients with PIN.

Abstract (sommario):

1534 Background: Recently normal prostate tissue has been found to contain a high concentration of retinoid X receptors (RXRs), they are found in the highest concentrations in ectodermal tissue. Loss of these receptors is associated with prostatic intraepithelial neoplasia (PIN), and can be present in patients with a normal PSA. There are 115,000 cases of high grade PIN discovered yearly in the United States.The drug bexarotene used to treat cutaneous T cell lymphoma (CTCL). The compound is not a true retinoid in structure, perusal of the structure reveals two aromatic rings one of which contains a carboxy group which would make one anticipate strong hydrogen bonding when it undergoes binding to the RXRs as if it were a retinoid, resulting in “up regulation” of the tissue with increase in differentiation to normal tissue. Based upon this it was felt that it would be fruitful to try bexarotene in High Grade PIN. Method: The diagnosis was based upon 12 biopsies which were done in conjunction with ultrasound localization of the biopsy site, with careful recording of there anatomical position. The patient was started on bexarotene 225 mg per day. The drug was given as a single dose once daily; this dose is 40% of the dose normally used to treat CTCL. The drug was administered for 30 doses During the period of therapy the patient was on Atorvastin T4 total was within the normal range. Results: Four weeks following the last dose of bexarotene the prostate was rebiopsied with 12 biopsies taken. Six of the biopsies were taken from the putative area, the rest in an enlarging target like pattern. The repeat biopsy was negative for the presence of PIN. 14 months later 12 more biopsies were obtained using the same technique, these repeat biopsies were also found to be negative; ie. 24 negative biopsies over 14 months. It is unlikely that the previously involved area was missed. Conclusion: If a mechanism of action were to be formulated, the induction of and increase in RXRs in normal prostate cells would be reasonable. Cells that undergo the formation of PIN, strong hydrogen bonding and inability of those cells to produce more receptors could result in apoptosis. Undoubtedly further study is required to evaluate the effect of this drug in high grade PIN. No significant financial relationships to disclose.
