Abstract
PURPOSE Intraductal carcinoma of the prostate (IDC-P) is a histological subtype that differs from conventional acinar adenocarcinoma in terms of its origin, appearance, and pathological features. For IDC-P, there is currently no recognized best course of action, and its prognosis is unclear. The goal of this study is to analyze independent prognostic factors in IDC-P patients and to develop and validate a nomogram to predict overall survival (OS) and cancer-specific survival (CSS). METHODS Clinical data for IDC-P patients were collected from the Surveillance, Epidemiology, and End Results database. To identify the independent variables influencing prognosis, multivariate Cox regression analysis was performed. A nomogram model was created utilizing these variables after comparing the variations in OS and CSS among various subgroups using Kaplan‒Meier curves. Internal validation of the nomograms was verified using the bootstrap resampling method. RESULTS The study included 280 IDC-P patients in total. Marital status, summary stage, grade, and the presence of lung metastases were significant factors impacting OS, and CSS was significantly influenced by marital status, summary stage, AJCC stage, the presence of lung metastases, the presence of bone metastases, and PSA according to univariate and multivariate Cox regression models (P < 0.05). Nomogram models were created to estimate OS and CSS using these parameters. The OS prediction model's C-index was 0.744, whereas the CSS prediction model's C-index was 0.831. CONCLUSION We developed and verified nomogram models for the prediction of 1-, 3-, and 5-year OS and CSS in patients with IDC-P. These nomograms serve as a resource for evaluating patient prognosis, therapy, and diagnosis, ultimately improving clinical decision-making accuracy.

Abstract
Intraductal carcinoma of the prostate, a unique histopathologic entity that is often observed (especially in advanced prostate cancer), is characterized by the proliferation of malignant cells within normal acini or ducts surrounded by a basement membrane. Intraductal carcinoma of the prostate is almost invariably associated with an adjacent high-grade carcinoma and is occasionally observed as an isolated subtype. Intraductal carcinoma of the prostate has been demonstrated to be an independent poor prognostic factor for all stages of cancer, whether localized, de novo metastatic, or castration-resistant. It also has a characteristic genetic profile, including high genomic instability. Recognizing and differentiating it from other pathologies is therefore important in patient management, and morphological diagnostic criteria for intraductal carcinoma of the prostate have been established. This review summarizes and outlines the clinical and pathological features, differential diagnosis, molecular aspects, and management of intraductal carcinoma of the prostate, as described in previous studies. We also present a discussion and future perspectives regarding intraductal carcinoma of the prostate.

Abstract
Prostate cancer (PCa) has a distinct molecular signature, including characteristic chromosomal translocations, gene deletions and defective DNA damage repair mechanisms. One crucial pathway involved is homologous recombination deficiency (HRD) and it is found in almost 20% of metastatic castrate-resistant PCa (mCRPC). Inherited/germline mutations are associated with a hereditary predisposition to early PCa development and aggressive behavior. BRCA2, ATM and CHECK2 are the most frequently HRD-mutated genes. BRCA2-mutated tumors have unfavorable clinical and pathological characteristics, such as intraductal carcinoma. PARP inhibitors, due to the induction of synthetic lethality, have been therapeutically approved for mCRPC with HRD alterations. Mutations are detected in metastatic tissue, while a liquid biopsy is utilized during follow-up, recognizing acquired resistance mechanisms. The mismatch repair (MMR) pathway is another DNA repair mechanism implicated in carcinogenesis, although only 5% of metastatic PCa is affected. It is associated with aggressive disease. PD-1 inhibitors have been used in MMR-deficient tumors; thus, the MMR status should be tested in all metastatic PCa cases. A surrogate marker of defective DNA repair mechanisms is the tumor mutational burden. PDL-1 expression and intratumoral lymphocytes have ambivalent predictive value. Few experimental molecules have been so far proposed as potential biomarkers. Future research may further elucidate the role of DNA damage pathways in PCa, revealing new therapeutic targets and predictive biomarkers.

Abstract
Simple Summary A cribriform structure is defined as a continuous proliferation of cells with intermingled lumina. Various entities may have a cribriform morphology within the prostate gland, ranging from normal, to benign, to borderline and even to malignant lesions. This review summarizes the morphologic features of entities that have a cribriform morphology within the prostate gland, with an emphasis on their differential diagnosis, molecular profile and clinical significance. The basic aim is to assist the pathologist with challenging and controversial cases and inform the clinician on the clinical implications of cribriform morphology. Abstract Cribriform glandular formations are characterized by a continuous proliferation of cells with intermingled lumina and can constitute a major or minor part of physiologic (normal central zone glands), benign (clear cell cribriform hyperplasia and basal cell hyperplasia), premalignant (high-grade prostatic intraepithelial neoplasia), borderline (atypical intraductal cribriform proliferation) or clearly malignant (intraductal, acinar, ductal and basal cell carcinoma) lesions. Each displays a different clinical course and variability in clinical management and prognosis. The aim of this review is to summarize the current knowledge regarding the morphological features, differential diagnosis, molecular profile and clinical significance of the cribriform-patterned entities of the prostate gland. Areas of controversy regarding their management, i.e., the grading of Intaductal Carcinoma, will also be discussed. Understanding the distinct nature of each cribriform lesion leads to the correct diagnosis and ensures accuracy in clinical decision-making, prognosis prediction and personalized risk stratification of patients.

Abstract
Simple Summary Most men with prostate cancer will live as long as those who do not have prostate cancer. However, some men will die early of their disease due to a particular type of prostate cancer associated with recurrence and metastasis: intraductal carcinoma of the prostate. In this review, we discuss the associations between intraductal carcinoma of the prostate and metastasis, and the contemporary knowledge about the molecular alterations of intraductal carcinoma of the prostate. Abstract Intraductal carcinoma of the prostate (IDC-P) is one of the most aggressive types of prostate cancer (PCa). IDC-P is identified in approximately 20% of PCa patients and is associated with recurrence, metastasis, and PCa-specific death. The main feature of this histological variant is the colonization of benign glands by PCa cells. Although IDC-P is a well-recognized independent parameter for metastasis, mechanisms by which IDC-P cells can spread and colonize other tissues are not fully known. In this review, we discuss the molecular portraits of IDC-P determined by immunohistochemistry and genomic approaches and highlight the areas in which more research is needed.

Abstract
Prostatic duct adenocarcinoma, characterized by pseudostratified columnar epithelium, has historically been considered invasive carcinoma, although it may commonly have an intraductal component. Usual (acinar) intraductal carcinoma of the prostate (IDC-P) is a noninvasive high-risk lesion typically associated with high-grade, high-stage prostate cancer. Whereas there have been rare biopsy studies of pure acinar IDC-P or IDC-P associated with only low-grade carcinoma, there have been no analogous series of IDC-P with cribriform or papillary ductal morphology on biopsy unassociated with invasive high-grade carcinoma. We identified 14 patients with biopsies showing IDC-P with ductal morphology, defined as prostatic duct adenocarcinoma confined to glands/ducts with immunohistochemically proven retention of basal cells. Our series includes 12 patients with pure IDC-P and 2 patients with concurrent low-volume Grade Group 1 invasive cancer in unassociated cores. Three patients underwent radical prostatectomy: 2/3 had high-grade cancer in their resection specimen (Grade Group 3, Grade Group 5), including 1 with advanced stage and nodal metastases; 1/3 had Grade Group 1 organ-confined carcinoma and spatially distinct IDC-P with ductal morphology. Five men had only follow-up biopsies: 2/5 had cancer (Grade Group 2, Grade Group 4); 1/5 had IDC-P (on 2 repeat biopsies); and 2/5 had benign transurethral resection of the prostate. In all 5 cases with invasive cancer, the invasive portion was comprised purely of acinar morphology; no invasive ductal component was identified. Five patients did not have follow-up biopsies and were treated with radiation therapy±androgen deprivation. One patient had no follow-up information. In an analogous situation to acinar IDC-P, we propose that rarely there is a precursor form of ductal adenocarcinoma that can exist without concurrent invasive high-grade carcinoma and propose the term "IDC-P with ductal morphology," consistent with the terminology for acinar prostate adenocarcinoma. Until more evidence is accumulated, we recommend reporting and treating patients with IDC-P with ductal morphology in a manner analogous to those with acinar IDC-P. As with pure IDC-P with acinar morphology, we would also recommend not grading pure IDC-P with ductal morphology. Finally, we propose a new addition to the diagnostic criteria of IDC-P to include intraductal lesions with ductal morphology consisting of papillary fronds or cribriform lesions lined by cytologically atypical pseudostratified epithelium.

Abstract
(1) Background: Prognostic grade group (PGG) is an important prognostic parameter in prostate cancer that guides therapeutic decisions. The cribriform pattern and intraductal carcinoma (IDC) are two histological patterns, that have additional prognostic significance. However, discrepancies exist regarding the handling of IDC according to the guidelines published by two international genitourinary pathology societies. Furthermore, whether, in addition to its presence, the amount of IDC is also of importance has not been studied before. Lastly, the handling of tertiary patterns has also been a matter of debate in the literature. (2) Methods: A total of 129 prostatectomy cases were retrieved and a detailed histopathologic analysis was performed. (3) Results: Two cases (1.6%) upgraded their PGG, when IDC was incorporated in the grading system. The presence and the amount of IDC, as well as the presence of cribriform carcinoma were associated with adverse pathologic characteristics. Interestingly, in six cases (4.7%) there was a difference in PGG when using the different guidelines regarding the handling of tertiary patterns. In total, 6.2% of the cases would be assigned a different grade depending on the guidelines followed. (4) Conclusions: These findings highlight a potential area of confusion among pathologists and clinicians and underscore the need for a consensus grading system.

Abstract
Intraductal carcinoma of the prostate (IDC-P) is an aggressive pathological pattern of prostate cancer (PCa). We investigated the association of IDC-P in prostate biopsy (PBx) with several pathological features after radical prostatectomy (RP) and its prognostic value in high-risk PCa. A total of 418 patients with high-risk PCa after RP were included in this study. IDC-P and its architectural patterns were identified according to the 2016 World Health Organization Classification. Chi-squared test and logistic regression were used to investigate the correlation between IDC-P and post-RP pathological features. Kaplan–Meier curves and Cox regression were applied to explore the prognostic value of IDC-P. IDC-P was identified in PBx in 36/418 (8.6%) patients. Logistic regression indicated that IDC-P in PBx was independently associated with several pathological features of RP, including Gleason score 8–10 (P < 0.001), seminal vesicular invasion (P < 0.001), and pathological T (pT) 3a (P = 0.043). Patients with IDC-P in PBx manifested poorer biochemical-free survival (BFS) than those without IDC-P (37.47 months vs not reached, P < 0.001). The addition of IDC-P in several prognostic nomograms could improve the predictive accuracy of these tools. We conclude that IDC-P in PBx is positively associated with several aggressive pathological features after RP in high-risk PCa. In addition, IDC-P in PBx could effectively predict the BFS of high-risk PCa patients after RP.

Abstract
Prostate cancer is a common malignancy, but only some tumors are lethal. Accurately identifying these tumors will improve clinical practice and instruct research. Aggressive cancers often have distinctive pathologies, including intraductal carcinoma of the prostate (IDC-P) and ductal adenocarcinoma. Here, we review the importance of these pathologies because they are often overlooked, especially in genomics and preclinical testing. Pathology, genomics, and patient-derived models show that IDC-P and ductal adenocarcinoma accompany multiple markers of poor prognosis. Consequently, "knowing what is growing" will help translate preclinical research to pinpoint and treat high-risk prostate cancer in the clinic.

Presence of corpora amylacea among prostate cancer cells: an unrecognised feature of intraductal carcinoma of the prostate. Pathology 2021; 53:574-578. [PMID: 34154844 DOI: 10.1016/j.pathol.2020.09.033] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/24/2020] [Revised: 08/26/2020] [Accepted: 09/02/2020] [Indexed: 11/22/2022]
Abstract
Corpora amylacea (CA) is usually present in benign prostatic ducts and acini, and its presence is considered suggestive of negative or low-risk prostate cancer. The clinicopathological definition of CA among prostate cancer cells (CAPCCs)-described as CA entirely surrounded by invasive cancer cells-has not been discussed. As intraductal carcinoma of the prostate (IDC-P) is a well-known adverse prognostic factor in prostate cancer, this study aimed to elucidate the relationship between CAPCC and IDC-P. We enrolled 366 patients who underwent robotic-assisted radical prostatectomies between 2012 and 2018 at Aichi Medical University Hospital. All surgical specimens were independently reviewed by two genitourinary pathologists. The median age of the patients was 68.5 years; the median serum prostate-specific antigen was 6.49 ng/mL. IDC-P was observed in 143 (39.1%) patients, while the presence of CAPCC was observed in 47 cases (12.8%). Patients with CAPCC were associated with more advanced clinical and pathological T stages, as well as Gleason scores, than those without CAPCC (p=0.018, p<0.001, p=0.036). Notably, the presence of CAPCC was significantly associated with the presence of IDC-P (39 cases) and a high Gleason score compared with the absence of CAPCC (12 cases) (p<0.001 and p=0.036, respectively). The presence of CAPCC is an adverse pathological feature, often closely related to IDC-P. Therefore, CAPCC may be a surrogate finding to detect IDC-P via haematoxylin and eosin staining.

Abstract
CONTEXT.— Controversies and uncertainty persist in prostate cancer grading. OBJECTIVE.— To update grading recommendations. DATA SOURCES.— Critical review of the literature along with pathology and clinician surveys. CONCLUSIONS.— Percent Gleason pattern 4 (%GP4) is as follows: (1) report %GP4 in needle biopsy with Grade Groups (GrGp) 2 and 3, and in needle biopsy on other parts (jars) of lower grade in cases with at least 1 part showing Gleason score (GS) 4 + 4 = 8; and (2) report %GP4: less than 5% or less than 10% and 10% increments thereafter. Tertiary grade patterns are as follows: (1) replace "tertiary grade pattern" in radical prostatectomy (RP) with "minor tertiary pattern 5 (TP5)," and only use in RP with GrGp 2 or 3 with less than 5% Gleason pattern 5; and (2) minor TP5 is noted along with the GS, with the GrGp based on the GS. Global score and magnetic resonance imaging (MRI)-targeted biopsies are as follows: (1) when multiple undesignated cores are taken from a single MRI-targeted lesion, an overall grade for that lesion is given as if all the involved cores were one long core; and (2) if providing a global score, when different scores are found in the standard and the MRI-targeted biopsy, give a single global score (factoring both the systematic standard and the MRI-targeted positive cores). Grade Groups are as follows: (1) Grade Groups (GrGp) is the terminology adopted by major world organizations; and (2) retain GS 3 + 5 = 8 in GrGp 4. Cribriform carcinoma is as follows: (1) report the presence or absence of cribriform glands in biopsy and RP with Gleason pattern 4 carcinoma. Intraductal carcinoma (IDC-P) is as follows: (1) report IDC-P in biopsy and RP; (2) use criteria based on dense cribriform glands (>50% of the gland is composed of epithelium relative to luminal spaces) and/or solid nests and/or marked pleomorphism/necrosis; (3) it is not necessary to perform basal cell immunostains on biopsy and RP to identify IDC-P if the results would not change the overall (highest) GS/GrGp part per case; (4) do not include IDC-P in determining the final GS/GrGp on biopsy and/or RP; and (5) "atypical intraductal proliferation (AIP)" is preferred for an intraductal proliferation of prostatic secretory cells which shows a greater degree of architectural complexity and/or cytological atypia than typical high-grade prostatic intraepithelial neoplasia, yet falling short of the strict diagnostic threshold for IDC-P. Molecular testing is as follows: (1) Ki67 is not ready for routine clinical use; (2) additional studies of active surveillance cohorts are needed to establish the utility of PTEN in this setting; and (3) dedicated studies of RNA-based assays in active surveillance populations are needed to substantiate the utility of these expensive tests in this setting. Artificial intelligence and novel grading schema are as follows: (1) incorporating reactive stromal grade, percent GP4, minor tertiary GP5, and cribriform/intraductal carcinoma are not ready for adoption in current practice.

Histological and immunohistochemical investigation of canine prostate carcinoma with identification of common intraductal carcinoma component. Vet Comp Oncol 2021; 20:38-49. [PMID: 33963663 PMCID: PMC9292867 DOI: 10.1111/vco.12704] [Citation(s) in RCA: 2] [Impact Index Per Article: 0.7] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/09/2020] [Revised: 03/31/2021] [Accepted: 05/06/2021] [Indexed: 12/03/2022]
Abstract
A limited number of species, including men and dogs, spontaneously develop prostate cancer (PC). The histological and molecular relevance of canine PC as a model for the disease in men remains controversial. To address this challenge, this study aimed to assess the histomorphology and expression of basal cell, urothelial and neuroendocrine markers [p63, high molecular weight cytokeratin (HMWCK), Uroplakin 3 (UPIII), neuron‐specific enolase (NSE)] in canine PC (n = 41). Based on histomorphology, 10/41 (24%), 21/41 (51%) and 9/41 (22%) were classified as adenocarcinoma (AC), urothelial carcinoma (UC), and mixed carcinoma, respectively. Tumour inflammation was common, frequently severe [20/41 (49%)], and associated with neutering (p < .02) and urothelial differentiation (p < .02). Most (36/40, 90%) cancers contained only rare cells with basal cell marker expression or were negative. The expression of UPIII was absent or weak in the majority (33/38, 87%) of tumours, with moderate to strong staining in the remaining cases. NSE expression in PC was rare and limited to 2/14 (14%) cases. Tumour extension into benign ducts and glands was a common finding with presence in 17/39 (44%) of carcinomas with and without urothelial differentiation. In conclusion, we confirm that canine PC is characterized by absent or weak expression of basal cell and urothelial markers. Although rare, NSE expression, potentially indicating neuroendocrine differentiation, is reported for the first time in canine PCa. Intraductal carcinoma of the prostate with concurrent invasive PCa (IDCP‐inv) is a frequent, not previously described, finding in dogs with PC.

Abstract
We aimed to confirm the predictive ability of the presence of intraductal carcinoma of the prostate (IDC-P) for prognosis and the associations between IDC-P and clinicopathological parameters. Studies were identified in PubMed, Cochrane Library, EMBASE, Web of Science, and SCOPUS up to December 1, 2019. Hazard ratios (HRs) for survival data and odds ratios for clinicopathological data with 95% confidence intervals (CIs) were extracted. Heterogeneity was evaluated by the I2 value, and quality was assessed by the Newcastle–Ottawa Scale criteria. A total of 4179 patients from 13 studies were included. The results showed that IDC-P presence was significantly associated with poor progression-free survival (PFS; HR = 2.31; 95% CI: 1.96–2.73), cancer-specific survival (HR = 1.89; 95% CI: 1.28–2.77), and overall survival (HR = 2.14; 95% CI: 1.53–3.01). In the subgroup analysis, IDC-P presence was significantly associated with poor PFS in prostate cancer treated by radical prostatectomy (HR = 2.48; 95% CI: 2.05–3.00) and treated by radiotherapy (HR = 2.83; 95% CI: 1.65–4.85). Regarding clinicopathological characteristics, patients with IDC-P presence had significantly higher tumor clinical stages, Gleason scores, probabilities of lymph node invasion, positive surgical margins, and positive extraprostatic extension. Our meta-analysis indicates that the presence of IDC-P is closely associated with poor prognosis and adverse clinicopathological characteristics. Our data support the value and clinical utility of the routine detection of IDC-P by pathological examination. These conclusions need further validation, and prospective studies are needed to find better treatment modalities other than traditional first-line therapy for patients with IDC-P.

Abstract
Intraductal carcinoma of the prostate (IDC-P) is a diagnostic entity characterized by architecturally or cytologically malignant-appearing prostatic glandular epithelium confined to prostatic ducts. Despite its apparent in situ nature, this lesion is associated with aggressive prostatic adenocarcinoma and is a predictor for poor prognosis when identified on biopsy or radical prostatectomy. This review discusses diagnosis, clinical features, histogenesis, and management of IDC-P, as well as current research and controversies surrounding this entity.

Abstract
Intraductal carcinoma of the prostate (IDC-P), a clinicopathological entity characterized by malignant prostatic epithelial cells growing within ducts and/or acini, has a distinct architectural pattern, cytological features, and biological behavior. Whereas most IDC-P tumors could be derived from adjacent high-grade invasive cancer via retrograde spreading of cancer cells along benign ducts and acini, a small subset of IDC-P may arise from the transformation and intraductal proliferation of precancerous cells induced by various oncogenic events. These isolated IDC-P tumors possess a distinct mutational profile and may function as a carcinoma in situ lesion with de novo intraductal outgrowth of malignant cells. Further molecular characterization of these two types of IDC-P and better understanding of the mechanisms underlying IDC-P formation and progression could be translated into valuable biomarkers for differential diagnosis and actionable targets for therapeutic interventions. PATIENT SUMMARY: Intraductal carcinoma of the prostate is an aggressive type of prostate cancer associated with high risk for local recurrence and distant metastasis. In this review, we discussed pathogenesis, biomarkers, differential diagnoses, and therapeutic strategies for this tumor.

Abstract
AIM Lymph node metastases (pN1) at prostatectomy are infrequent but impact prognosis. Traditional prostate nomograms assess age, serum prostatic-specific antigen (PSA), clinical stage, and biopsy parameters to inform decisions on pelvic lymph node dissection. The impact of intraductal carcinoma (IDC) and cribriform pattern 4 (CC) on nodal metastases has yet to be explored. METHODS Five hundred forty three radical prostatectomy cases were reviewed for International Society of Urological Pathology (ISUP) grade, CC/IDC, T- and N-stage. Two hundred seventy five cases had matched biopsies with age, serum PSA, CC/IDC and ISUP grade recorded. The association of CC/IDC with pN1 in both prostatectomy and biopsy settings was assessed using Fisher's exact test, as well as univariable (UVA) and multivariable (MVA) logistic regression. RESULTS In 543 men in whom a prostatectomy was performed, a nodal dissection was also available in 340 (63%), and 37 (10.9%) of them had pN1 disease. ISUP grade, stage and CC/IDC were significantly associated with pN1 (p < 0.001). UVA regression showed grade (p < 0.001, odds ratio [OR]: 5.85), CC/IDC (p = 0.003, OR: 14.06) and T stage (p = 0.004, OR: 61.94) associated with pN1 as did MVA regression: grade (p = 0.010, OR: 2.81), CC/IDC (p = 0.015, OR: 5.12) and T stage (p = 0.016, OR: 30.38). In 275 patients with matched biopsies, a nodal dissection was performed in 197 (71.6%) and 20 (10.2%) patients had pN1 disease. On UVA regression, grade (p < 0.001, OR: 6.33), CC/IDC (p = 0.013, OR: 3.28), serum PSA (p = 0.001, OR: 1.08) and age (p = 0.047, OR: 1.07) were significant for pN1 at prostatectomy. All parameters including specifically grade (p = 0.007, OR: 5.35) and CC/IDC (p = 0.018, OR: 4.42) on biopsies predicted for pN1 by multivariate analysis. CONCLUSION CC/IDC in prostatectomy and biopsy significantly associates with pN1. Incorporation of CC/IDC status into preoperative nomograms may optimize patient selection for pelvic nodal dissection.

Abstract
PURPOSE To retrospectively review our 20 year experience of multidisciplinary management of non-metastatic ductal prostate cancer (dPC), a rare but aggressive histological subtype of prostate cancer whose optimal therapeutic approach is still controversial. METHODS Histologically confirmed dPC patients undergoing primary, curative treatment [radical prostatectomy (RP), external beam radiotherapy (EBRT), and androgen deprivation therapy (ADT)] were included, and percentage of ductal and acinar pattern within prostate samples were derived. Survival outcomes were assessed using the subdistribution hazard ratio (SHR) and Fine-and-Gray model. RESULTS From January 1997 to December 2016, 81 non-metastatic dPC fitted selection criteria. Compared to surgery alone, SHR for progression-free survival and cancer-specific mortality were 2.8 (95% CI 0.6-13.3) and 1.3 (95% CI 0.1-16.2) for exclusive EBRT, 2.7 (95% CI 0.6-13.0) and 6.5 (95% CI 0.6-69.8) for adjuvant EBRT, 4.9 (95% CI 0.7-35.5) and 5.8 (95% CI 0.5-65.6) for salvage EBRT post-prostatectomy recurrence, and 3.2 (95% CI 0.7-14.0) and 3.9 (95% CI 0.3-44.1) for primary ADT (P = 0.558; P = 0.181), respectively. Comparing multimodal treatment and monotherapy confirmed the above trends. Local recurrence more typically occurred in pure dPC patients, mixed histology more frequently produced metastatic spread (29.6% relapse in total, P = 0.026). CONCLUSION Albeit some limitations affected the study, our findings support the role of local treatment to achieve better disease control and improve quality of life. Different behavior, with typical local growth in pure dPC, higher distant metastatization in the mixed form, might influence treatment response. Given its poor prognosis, we recommend multidisciplinary management of dPC.

Abstract
The prognostic significance of the Gleason grading system has been well established. However, individual Gleason patterns comprise heterogeneous morphologies which might add additional prognostic information. Recent evidence suggests that Gleason pattern 4 with cribriform growth pattern is associated with an adverse prognosis. To determine the association between cribriform pattern on biopsies and pathological findings on subsequent prostatectomies, we evaluated the presence of cribriform architecture in a prospective cohort of 367 men from 2014 to 2018 treated at a single institution. Cribriform architecture was present in 63.5% of all biopsies and was correlated with the overall extent of Gleason pattern 4. In addition, cribriform morphology on biopsy showed a statistically significant association with higher Gleason grade and increased pathological stage and nodal metastasis. In a subset analysis of cases with Grade Group 2 (Gleason score 3 + 4, n = 208), these associations did not reach statistical significance, but the presence of cribriform growth in this subgroup showed a trend toward increased upgrading to Grade Group 5 (Gleason score 9/10) (1 [0.5%] vs. 5 [2.4%], P = 0.06). This large prospective study comparing biopsy and prostatectomy finding of cribriform architecture demonstrates that cribriform pattern 4 is associated with adverse prognostic features and highlights the relevance for recognizing specific morphologies with distinct biological and clinical features.

The influence of the presence of intraductal carcinoma of the prostate on the grade group system's prognostic performance. Prostate 2019; 79:1065-1070. [PMID: 31025722 DOI: 10.1002/pros.23818] [Citation(s) in RCA: 20] [Impact Index Per Article: 4.0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 02/09/2019] [Accepted: 04/09/2019] [Indexed: 01/16/2023]
Abstract
BACKGROUND Although the presence of intraductal carcinoma of the prostate (IDC-P) influences biochemical failure in radical prostatectomy patients, no data are available regarding the impact of its integration into the classification grade group system. Thus, the aim of this study was to enhance the utility of the grade group system by integrating the presence of IDC-P. METHODS This study was a retrospective evaluation of 1019 patients with prostate cancer who underwent radical prostatectomy between 2005 and 2013 without neoadjuvant or adjuvant therapy. The data on age, prostate-specific antigen (PSA) level at diagnosis, pathological T stage (pT), presence of Gleason pattern 5 (GP5), presence of IDC-P, and surgical margin status were analyzed to predict PSA recurrence after prostatectomy. RESULTS The median patient age was 67 (range, 45-80) years and the median initial PSA level was 6.8 (range, 0.4-82) ng/mL. The median follow-up period was 82 (range, 0.7-148) months. IDC-P was detected in 157 patients (15.4%). Among these patients, the increase in the positive rate of IDC-P correlated with tumor upgrading. The grade groups (GGs) were as follows: GG1 without IDC-P, 16.0% (n = 163); GG2 without IDC-P, 46.1% (n = 470); GG3 without IDC-P, 15.7% (n = 160); GG4 without IDC-P, 2.6% (n = 27); GG5 without IDC-P, 4.1% (n = 42); any GG with IDC-P, 15.4% [n = 157; GG 2 (n = 29); GG3 (n = 60); GG4 (n = 13); GG5 (n = 55)]. Any grade Group with IDC-P showed significantly worse prognosis than any other group without IDC-P (P < 0.0001). In a multivariate analysis, integration of the IDC-P into the Grade Groups, the PSA level at diagnosis, and the surgical margin status were significant prognostic predictors (P < 0.0001, < 0.0001 and < 0.0001, respectively). CONCLUSIONS Integrating the presence of IDC-P into the grade group system will result in more accurate predictions of patient outcome.

Abstract
(Objective) We investigated the prognostic significance of intraductal carcinoma of the prostate (IDC-P) in radical prostatectomy specimens. (Materials and methods) We evaluated 441 patients treated with radical prostatectomy and analyzed data on IDC-P, lymph node metastases, Gleason score, seminal vesicle invasion, extraprostatic extension, surgical margin, total cancer volume, and zonal origin of dominant cancer focus in radical prostatectomy specimens. The median follow-up was 50 months (range 6-164 months). (Results) We identified IDC-P in 112 cases (25.4%). The five-year biochemical progression-free survival rate in patients with IDC-P was significantly lower than for those without IDC-P (35.8% vs 69.6%; p<0.0001). In a univariate analysis, IDC-P (p<0.0001), lymph node metastases (p=0.0022), Gleason score (p<0.0001), seminal vesicle invasion (p<0.0001), extraprostatic extension (p<0.0001), surgical margin (p<0.0001) and total cancer volume (p<0.0001) were significantly associated with the biochemical progression-free survival. In a multivariate analysis, Gleason score (p<0.0001), IDC-P (p=0.0002), seminal vesicle invasion (p=0.0011), extraprostatic extension (p=0.0012), surgical margin (p=0.0019) and lymph node metastases (p=0.0402) were significantly associated with biochemical progression-free survival. (Conclusions) The presence of IDC-P is an independent factor of biochemical recurrence in prostate cancer patients treated with radical prostatectomy. We therefore recommend that the presence of IDC-P in radical prostatectomy specimens be reported.

Abstract
Context.—
Recent studies and a few reviews suggest that presence of invasive cribriform lesions (ICLs) in prostatic acinar adenocarcinoma correlates with adverse outcomes. However, a systematic review with meta-analysis on this correlation is currently lacking.
Objective.—
To compare the likelihood of adverse outcomes by the status of ICLs in prostatic acinar adenocarcinoma with the meta-analysis of high-quality published data and institutional experience.
Data Sources.—
PubMed, Scopus, manually searched references, and institutional data.
Study Selection.—
Observational retrospective case-control studies or prospective cohort studies of adverse outcomes stratified by the status of ICLs were selected.
Data Extraction.—
Study quality was analyzed. The prevalence of adverse outcomes stratified by the status of ICLs was extracted.
Conclusions.—
Eighty-five cases were reviewed. Extraprostatic extension, seminal vesicle invasion, and regional lymph node metastasis were observed in 18 (45%), 14 (35%), and 7 (17.5%) of the 40 cases with cribriform lesions, respectively. These features were observed in 4 (8.9%), 1 (2.2%), and 0 (0%) of the 45 cases without ICLs. During the follow-up, biochemical prostate-specific antigen recurrence, local recurrence, and metastasis/disease-specific death were documented in 7 (17.5%), 2 (5%), and 2 (5%) of the 40 cases with ICLs. These poor outcomes were found in 6 (13.3%), 1 (2.2%), and 1 (2.2%) of the 45 cases without ICLs. Meta-analysis revealed a significant increase in the risk of adverse outcomes in patients who had ICLs relative to those who did not (odds ratio, 3.95; 95% CI, 2.61–5.97; I2 = 53%; Z = 6.52; P < .01). These results suggest that presence of ICLs is associated with adverse outcomes.

Abstract
From the advent of the Gleason grading system for prostate cancer, cancer displaying intraluminal necrotic cells and/or karyorrhexis within cribriform/solid architecture, a phenomenon termed "comedonecrosis," has been assigned pattern 5. Intraductal carcinoma (IDC-P) shows morphologic overlap with high-grade cribriform/solid adenocarcinoma architecturally and cytologically and may also show central necrosis, yet due to the presence of basal cells at the duct periphery is not currently assigned a grade in clinical practice. On the basis of observations from routine clinical cases, we hypothesized that comedonecrosis was more significantly associated with IDC-P than invasive disease. From a large series of mapped radical prostatectomy specimens (n=933), we identified 125 high-grade (≥Gleason score 4+3=7), high-volume tumors with available slides for review. All slides were examined for the presence of unequivocal comedonecrosis. Standard immunohistochemistry for basal cell markers was performed to detect basal cell labeling in these foci. In total, 19 of 125 (15%) cases showed some ducts with comedonecrosis-9 cases with 1 focus and 10 cases with ≥2 foci; in all, a total of 73 foci of true comedonecrosis were evaluated. Immunohistochemical stains revealed labeling for basal cell markers in a basal cell distribution for at least some comedonecrosis foci in 18 of 19 (95%) cases, 12 with IDC-P exclusively and 6 with a mix of IDC-P and invasive carcinoma comedonecrosis foci. These results suggest that comedonecrosis is strongly associated with IDC-P and hence, the routine assignment of pattern 5 to carcinoma exhibiting comedonecrosis should be reconsidered.

Abstract
BACKGROUND To investigate the effect of intraductal carcinoma of the prostate (IDC-P) in radical prostatectomy (RP) specimens in the context of the site of recurrence, time to recurrence, and cancer-specific survival in two academic cohorts of locally, regionally, or distantly recurrent prostate cancer. METHODS Our cohort included men enrolled into two academic tissue repositories from 1993 to 2011, who were treated with first-line RP who later experienced local recurrence, regional recurrence, or distant metastasis (together termed clinical recurrence, CR). RP material was reviewed to identify IDC-P and to update grading to current standards. The primary endpoint was the initial location of CR. Secondary endpoints included time to CR and cancer-specific survival. Pearson's chi-square, Welch's t-test, Mann-Whitney U test and Fisher's exact test were performed for univariate analyses. Multinomial logistic regression was used for multivariate analyses. Cancer-specific survival was analyzed with the generalized Wilcoxon test and Cox regression. RESULTS Eighty-five patients with CR were included in the analysis. IDC-P was present in 78.5% of patients from Center 1 and 70.0% from Center 2 (P = 0.547). IDC-P was independently associated with distant metastasis at initial CR (multivariate odds ratio = 6.27, P = 0.015). IDC-P status did not affect time to recurrence; median survival without recurrence was at 53 months for IDC-P(+) and at 50 months for IDC-P(-) (P = 0.441). Distant metastases at the initial CR event had a 36% reduction of cancer-specific survival compared to local recurrences (P = 0.007). Additionally, prostatic-bed radiotherapy (adjuvant or salvage for biochemical recurrence before distant metastasis) was associated with a 25% reduction in cancer-specific mortality compared to no radiotherapy (P = 0.023). Similar reduction in cancer-specific mortality was observed in the subgroup of patients with distant metastasis and IDC-P when treated with radiotherapy (29%, P = 0.050). CONCLUSIONS In our cohort, presence of IDC-P was an independent factor for distant metastasis at initial CR, but did not have a significant impact on time to CR. Furthermore, metastatic patients showed statistically reduced cancer-specific mortality when treated with radiotherapy. This reduction in cancer-specific mortality was also identified in patients with IDC-P. Future large scale validation studies should take into account the presence of IDC-P and confirm its impact on disease progression.

Abstract
OBJECTIVE To identify risk factors of biochemical recurrence after radical prostatectomy in high-risk patients. METHODS A total of 191 high-risk prostate cancer patients according to the D'Amico classification treated with radical prostatectomy at a single institution between April 2000 and December 2013 were enrolled. The pathological evaluation including intraductal carcinoma of prostate was reassessed, and the clinical and pathological risk factors of biochemical recurrence were analyzed. RESULTS The median follow up after radical prostatectomy was 49 months. The 5-year biochemical recurrence-free survival rate after radical prostatectomy in high-risk prostate cancer patients was 41.6%. Initial prostate-specific antigen, pathological Gleason score, seminal vesicle invasion, extraprostatic extension and intraductal carcinoma of the prostate were significantly associated with biochemical recurrence-free survival. The 5-year biochemical recurrence-free survival rates in patients with zero, one, two and three of these risk factors were 92.9%, 70.7%, 38.3% and 28.8%, respectively. In patients with four or more factors, the biochemical recurrence-free survival rate was 6.1% after 18 months. CONCLUSIONS In D'Amico high-risk patients treated with radical prostatectomy, risk factors for biochemical recurrence can be identified. Patients with fewer risk factors have longer biochemical recurrence-free survival, even among these high-risk cases.

Abstract
PURPOSE The degree to which intraductal carcinoma of the prostate (IDC-P) affects clinical course remains poorly understood owing to small sample sizes from single-center studies. We sought to determine prognostic factors and outcomes associated with IDC-P in radical prostatectomy (RP) specimens. MATERIALS AND METHODS This is a retrospective study of RP during 2004 to 2013 using Surveillance, Epidemiology, and End Results to compare IDC-P with non-IDC-P. The effect of IDC-P on overall and disease-specific survival was assessed using Cox regression with a median follow-up of 4.8 years (interquartile range [IQR]: 2.6-7.0y; P = 0.01). Median prostate-specific antigen at diagnosis in IDC-P vs. non-IDC-P was similar (P = 0.23) at 6.2 (IQR: 4.6-13.0) vs. 6.1ng/ml (IQR: 4.6-9.8). RESULTS We identified 159,777 RP from 2004 to 2013, and 242 (0.002%) had IDC-P pathologic features. IDC-P was associated with a greater likelihood of extraprostatic stage, pT3/T4, 45.9% vs. 21.6% (P<0.001), higher grade, GS≥ 7, 79.3% vs. 62.7% (P<0.001), lymph node metastases, 5.8% vs. 2.4% (P<0.001), and positive surgical margins, 25.6% vs. 19.5% (P = 0.02). IDC-P was associated with a 3-fold increase in prostate cancer-specific mortality relative to non-IDC-P (hazard ratio = 3.0, 95% CI: 1.5-5.7; P<0.01). Limitations include retrospective design and potential underreporting of IDC-P that leads to underestimation of the true effect size. CONCLUSIONS The significance of IDC-P features has been recently recognized by the World Health Organization and it is associated with high-grade, extraprostatic features, and worse prostate cancer-specific mortality. Understanding its prognostic significance better guides adjuvant therapies and clinical trials.

Abstract
CONTEXT - Precursor lesions of urologic malignancies are established histopathologic entities, which are important not only to recognize for clinical purposes, but also to further investigate at the molecular level in order to gain a better understanding of the pathogenesis of these malignancies. OBJECTIVE - To provide a brief overview of precursor lesions to the most common malignancies that develop within the genitourinary tract with a focus on their clinical implications, histologic features, and molecular characteristics. DATA SOURCES - Literature review from PubMed, urologic pathology textbooks, and the 4th edition of the World Health Organization Classification of Tumours of the Urinary System and Male Genital Organs. All photomicrographs were taken from cases seen at Weill Cornell Medicine or from the authors' personal slide collections. CONCLUSIONS - The clinical importance and histologic criteria are well established for the known precursor lesions of the most common malignancies throughout the genitourinary tract, but further investigation is warranted at the molecular level to better understand the pathogenesis of these lesions. Such investigation may lead to better risk stratification of patients and potentially novel treatments.

Abstract
Intraductal carcinoma of the prostate (IDC-P) is characterized by prostatic carcinoma involving ducts and/or acini. The presence of IDC-P is usually associated with a high-grade Gleason score, large tumor volume, and adverse prognostic parameters, including extraprostatic extension and seminal vesicle invasion. When present, IDC-P is associated with worse outcomes, regardless of treatment status. IDC-P is included in a broader diagnostic category of atypical cribriform lesions of the prostate gland. This category of lesions also includes high-grade prostatic intraepithelial neoplasia (HGPIN), urothelial carcinoma involving prostatic ducts or acini, and prostatic ductal adenocarcinoma, amongst other intraductal proliferations. Differentiating between these entities is important as they have differing therapeutic and prognostic implications for patients, although differential diagnosis thereof is not always straightforward. The present review discusses IDC-P in regards to its morphological characteristics, molecular features, and clinical outcomes. Given the current state of knowledge, the presence of IDC-P should be evaluated and documented correctly in both radical prostatectomy and needle biopsy specimens, and the clinical implications thereof should be taken into consideration during treatment and follow up.

Abstract
BACKGROUND The main morphologic differential diagnosis of intra-ductal carcinoma of prostate (IDC-P) is high grade prostatic intraepithelialneoplasia (HGPIN). Since IDC-P, unlike PIN, was strongly correlated with aggressive prostate cancer, differentiation of these is too necessary. So we evaluated immunohistopathological patterns and the prognostic factors of IDC-P and HGPIN, in radical prostatectomy samples. METHODS We evaluated 250 radical prostatectomy and detected 210 cases of prostatic adenocarcinoma without IDC-P foci, 40 cases with adenocarcinoma concomitant IDC-P, and 40 cases HGPIN; therefore, we evaluated immunohistopathological criteria in these groups. Data were analyzed using SPSS and P-value <0.05 was considered as the statistical significant level. RESULTS PSA level was significantly higher in IDC-P compared with non-IDC-P patients (15.7 ± 3.1 vs. 10.2 ± 4.3, P = 0.041). All pathological and morphologic features, also invasions factors were higher in IDC-P compared to non-IDC-P groups (P < 0.001). P63 was positive expressed in all IDC-P and HGPIN specimen. PTEN protein was diffusely expressed in the cytoplasm of all HGPIN but in 4 (11.1%) of IDC-P. PTEN and P63 were negative in adenocarcinoma foci. CONCLUSION We found that IDC-P had a unique histoclinical feature and was strongly associated with poor prognostic factors. Diagnosis and report of IDC-P should be considered in all prostate specimens. Also, we recommend PTEN IHC application for differentiated IDC-P from HGPIN in biopsies.

Abstract
For many tumor entities, especially in breast cancer, an intraductal carcinoma is generally perceived as a precursor lesion, which precedes the emergence of invasive carcinoma. Therefore, in addition to parameters of the invasive carcinoma, histological parameters of the intraductal component have always played an important role in therapy planning of breast cancer. This is different in prostate cancer and although the term "intraductal carcinoma" has long been propagated by some authors, its routine use remains rare and inconsistent. This is certainly not only due to the far simpler therapy options of prostate cancer, in which focal and organ-preserving therapies still play a subordinate role, but also due to substantial interobserver variation and our inconsistent perception of intraductal carcinomas. This article gives a brief overview of currently available literature on this topic and explains why intraductal carcinoma of the prostate deserves our attention. In contrast to breast cancer, intraductal carcinoma of the prostate usually represents a post-invasive lesion, in which an aggressive tumor exhibits spread into pre-existing ducts; however, in rare cases, intraductal carcinoma may represent a true precursor lesion.

Abstract
OBJECTIVE The distribution of intraductal carcinoma of the prostate (IDC-P) and other intraductal lesions associated with IDC-P was evaluated in the cancer foci on radical prostatectomy specimens. MATERIALS AND METHODS We reviewed slide in 412 cases treated by radical prostatectomy without neoadjuvant therapy. Mapping study was performed with regard to IDC-P, other intraductal lesions associated with IDC-P and invasive carcinoma. RESULTS We identified 98 cases (23.8%) and 102 cancer foci associated with IDC-P. In these all cancer foci, IDC-P was associated with invasive carcinoma and other intraductal neoplastic lesions with tufting, micropapillary and loose cribriform patterns were contiguous and admixed with IDC-P in 83 cancer foci (81.4%). There were lesions with invasive carcinoma around the IDC-P in 95 cancer foci (93.1%) and lesions without invasive carcinoma around IDC-P in 66 foci (64.7%). The latter lesions existed in the marginal areas of the cancer foci in 63 (61.8%) and in the central areas of the cancer foci in 14 (13.7%). In 5 cancer foci (4.9%), volume of IDC-P was larger than that of invasive carcinoma. CONCLUSIONS The distribution of IDC-P with dense cribriform and solid patterns varied in cancer foci, and intraductal lesions with tufting, micropapillary and loose cribriform patterns were frequently seen in area contiguous and admixed with IDC-P. The latter lesion may be low grade morphology of IDC-P, although the lesions could not be distinguished from high grade prostatic intraepithelial neoplasia.

Utility of PTEN and ERG immunostaining for distinguishing high-grade PIN from intraductal carcinoma of the prostate on needle biopsy. Am J Surg Pathol 2015; 39:169-78.

Abstract
Intraductal carcinoma of the prostate and high-grade prostatic intraepithelial neoplasia (PIN) have markedly different implications for patient care but can be difficult to distinguish in needle biopsies. In radical prostatectomies, we demonstrated that PTEN and ERG immunostaining may be helpful to resolve this differential diagnosis. Here, we tested whether these markers are diagnostically useful in the needle biopsy setting. Separate or combined immunostains were applied to biopsies containing morphologically identified intraductal carcinoma, PIN, or borderline intraductal proliferations more concerning than PIN but falling short of morphologic criteria for intraductal carcinoma. Intraductal carcinoma occurring with concurrent invasive tumor showed the highest rate of PTEN loss, with 76% (38/50) lacking PTEN and 58% (29/50) expressing ERG. Of biopsies containing isolated intraductal carcinoma, 61% (20/33) showed PTEN loss and 30% (10/33) expressed ERG. Of the borderline intraductal proliferations, 52% (11/21) showed PTEN loss and 27% (4/15) expressed ERG. Of the borderline cases with PTEN loss, 64% (7/11) had carcinoma in a subsequent needle biopsy specimen, compared with 50% (5/10) of PTEN-intact cases. In contrast, none of the PIN cases showed PTEN loss or ERG expression (0/19). On needle biopsy, PTEN loss is common in morphologically identified intraductal carcinoma yet is very rare in high-grade PIN. Borderline intraductal proliferations, especially those with PTEN loss, have a high rate of carcinoma on resampling. If confirmed in larger prospective studies, these results suggest that PTEN and ERG immunostaining may provide a useful ancillary assay to distinguish intraductal carcinoma from high-grade PIN in this setting.

Abstract
BACKGROUND Intraductal carcinoma of prostate (IDC-P) was usually found to be co-exist with conventional aggressive prostate adenocarcinoma. The presence of IDC-P was considered as an adverse pathological factor, which was associated with high Gleason score, large prostate volume and accelerated disease progression. However, no any information is available on the presence of IDC-P diagnosed by needle biopsy in patients with metastatic prostate cancer. We investigated the incidence and prognostic value of intraductal carcinoma of prostate (IDC-P) in initial diagnosed metastatic prostate cancer. METHODS We included 278 patients with initial diagnosed metastatic prostate cancer treated between 2008 and 2011, all the pathological diagnosis were from ultrasonic-guided transperineal needle biopsy. IDC-P was strictly defined according to Epstein's criteria. Analyzed factors included age, Eastern Cooperative Oncology Group (ECOG) score, clinical T staging, Gleason scores, baseline prostate specific antigen (PSA), alkaline phosphatase (ALP), hemoglobin (HGB), PSA normalization, and the presence of IDC-P. RESULTS Totally, IDC-P was found in 57/278 (20.5%) cases. Univariate analysis showed that, compared with cases without IDC-P, cases with IDC-P was definitely associated with much shorter CRPC-free survival (CFS) time (46.05 ± 1.39 vs. 22.98 ± 1.80 months, P = 0.000) and OS time (50.38 ± 1.18 vs. 36.43 ± 2.10 months, P = 0.000). Multivariate analysis showed that the presence of IDC-P was the only independent prognostic factor associated with poor CFS (HR = 4.886, P = 0.011) and OS (HR = 1.945, P = 0.020). Further sub-analysis showed, even among patients with higher Gleason score (≥8) (n = 158), IDC-P was still significantly and inversely associated with CFS and OS (the median CFS time: 40 versus 22 months; P = 0.000; the median OS time: 54 vs. 36 months, P = 0.000). Again, Cox's regression model confirmed that only the presence of IDC-P was still not only an independent prognostic factor predicting shorter time of CRPC (HR = 4.031, P = 0.035), but also for poorer OS (HR = 2.499, P = 0.006). CONCLUSIONS The presence of IDC-P in initial diagnosed metastatic prostate cancer, even among patients with more aggressive pattern, was firstly found to be significantly and independently associated with earlier occurrence of CRPC and poorer OS. We recommended the presence of IDC-P should be a routine record in pathological report of clinical diagnosis and other potential therapeutic regimen might be added to intervene in the integrated therapy as early as possible.

Abstract
Intraductal carcinoma of the prostate is characterized by prostatic carcinoma cells growing within ducts and/or acini. These tumors are usually associated with a high-grade Gleason score, large tumor volume and advanced stage. Intraductal carcinoma of the prostate is also a well-known adverse independent prognostic factor regardless of treatment. Recent studies have shown that intraductal carcinoma of the prostate is a distinctive disease entity that is different from invasive prostate carcinoma, which is generally invasive. Although the Gleason score does not consider intraductal carcinoma of the prostate, some cribriform prostate carcinomas graded as pattern 4 could be considered as intraductal carcinomas. The definition of intraductal carcinoma of the prostate is not unified, because it can occur with or without invasive prostate carcinoma. Furthermore, diagnosis of intraductal carcinoma of the prostate without invasive prostate carcinoma by needle biopsy is crucial, but is a rare event. Differential diagnosis of intraductal carcinoma of the prostate includes several pathologies. This is especially true for high-grade prostatic intraepithelial neoplasia, although its distinction is not always straightforward. The present review discusses the concept of intraductal carcinoma of the prostate, and also describes its morphological characteristics, molecular features and clinical outcome. Given the current state of knowledge, the presence of intraductal carcinoma of the prostate should be evaluated and documented correctly in both radical prostatectomy and needle biopsy, and the clinical implications should be taken into consideration during treatment and follow up.

Abstract
BACKGROUND Intraductal carcinoma of the prostate (IDC-P) is a distinct clinicopathologic entity associated with aggressive prostate cancer (PCa). PCa patients carrying a breast cancer 2, early onset (BRCA2) germline mutation exhibit highly aggressive tumours with poor prognosis. OBJECTIVE To investigate the presence and implications of IDC-P in men with a strong family history of PCa who either carry a BRCA2 pathogenic mutation or do not carry the mutation (BRCAX). DESIGN, SETTING, AND PARTICIPANTS Patient-derived xenografts (PDXs) were generated from three germline BRCA2 mutation carriers and one BRCAX patient. Specimens were examined for histologic evidence of IDC-P. Whole-genome copy number analysis (WG-CNA) was performed on IDC-P from a primary and a matched PDX specimen. OUTCOME MEASUREMENTS AND STATISTICAL ANALYSIS The incidence of IDC-P and association with overall survival for BRCA2 and BRCAX patients were determined using Kaplan-Meier analysis. RESULTS AND LIMITATIONS PDXs from BRCA2 tumours showed increased incidence of IDC-P compared with sporadic PCa (p=0.015). WG-CNA confirmed that the genetic profile of IDC-P from a matched (primary and PDX) BRCA2 tumour was similar. The incidence of IDC-P was significantly increased in BRCA2 carriers (42%, n=33, p=0.004) but not in BRCAX patients (25.8%, n=62, p=0.102) when both groups were compared with sporadic cases (9%, n=32). BRCA2 carriers and BRCAX patients with IDC-P had significantly worse overall and PCa-specific survival compared with BRCA2 carriers and BRCAX patients without IDC-P (hazard ratio [HR]: 16.9, p=0.0064 and HR: 3.57, p=0.0086, respectively). CONCLUSIONS PDXs revealed IDC-P in patients with germline BRCA2 mutations or BRCAX classification, identifying aggressive tumours with poor survival even when the stage and grade of cancer at diagnosis were similar. Further studies of the prognostic significance of IDC-P in sporadic PCa are warranted. PATIENT SUMMARY Intraductal carcinoma of the prostate is common in patients with familial prostate cancer and is associated with poor outcomes. This finding affects genetic counselling and identifies patients in whom earlier multimodality treatment may be required.

Abstract
OBJECTIVES To review and report our local experience in the management of ductal adenocarcinoma of the prostate. METHODS Retrospective review of patients diagnosed with ductal adenocarcinoma of the prostate in two regional urological centres in Hong Kong during 1995-2009. Clinical information, treatment and outcomes were retrieved for further analysis. RESULTS We identified 19 Chinese patients diagnosed with ductal adenocarcinoma of the prostate. Majority of our patients presented with retention of urine and haematuria. At presentation, seven patients were already at an advanced stage with evidence of rectal invasion or distant metastasis. The overall treatment outcome was poor with high failure rate after either local or systemic hormonal therapy. CONCLUSION We observed a predilection of this tumour to be locally aggressive, and hence a relatively high incidence of intra-luminal growth and rectal invasion. We observed a high failure rate after either radical prostatectomy or hormonal therapy.

Abstract
The 2011 International Association for the Study of Lung Cancer (IASLC)/American Thoracic Society (ATS)/European Respiratory Society (ERS) lung adenocarcinoma classification emphasizes the prognostic significance of histologic subtypes. However, one limitation of this classification is that the highest percentage of patients (∼40%) is classified as acinar predominant tumors, and these patients display a spectrum of favorable and unfavorable clinical behaviors. We investigated whether the cribriform pattern can further stratify prognosis by histologic subtype. Tumor slides from 1038 patients with stage I lung adenocarcinoma (1995-2009) were reviewed. Tumors were classified according to the IASLC/ATS/ERS classification. The percentage of cribriform pattern was recorded, and the cribriform predominant subtype was considered as a subtype for analysis. The log-rank test was used to analyze the association between histologic variables and recurrence-free probability. The 5-year recurrence-free probability for patients with cribriform predominant tumors (n=46) was 70%. The recurrence-free probability for patients with cribriform predominant tumors was significantly lower than that for patients with acinar (5-year recurrence-free probability, 87%; P=0.002) or papillary predominant tumors (83%; P=0.020) but was comparable to that for patients with micropapillary (P=0.34) or solid predominant tumors (P=0.56). The recurrence-free probability for patients with ≥10% cribriform pattern tumors (n=214) was significantly lower (5-year recurrence-free probability, 73%) than that for patients with <10% cribriform pattern tumors (n=824; 84%; P<0.001). In multivariate analysis, patients with acinar predominant tumors with ≥10% cribriform pattern remained at significantly increased risk of recurrence compared with those with <10% cribriform pattern (P=0.042). Cribriform predominant tumors should be considered a distinct subtype with a high risk of recurrence, and presence (≥10%) of the cribriform pattern is an independent predictor of recurrence, identifying a poor prognostic subset of acinar predominant tumors. Our findings highlight the important prognostic value of comprehensive histologic subtyping and recording the percentage of each histologic pattern, according to the IASLC/ATS/ERS classification with the addition of the cribriform subtype.

Abstract
BACKGROUND Intraductal carcinoma of the prostate (IDC-P) is an adverse prognostic factor for radical prostatectomy (RP). The endpoint in most IDC-P studies is increased prostate-specific antigen (PSA) levels. The aim of this study was to evaluate whether IDC-P in RP specimens is an adverse prognostic factor for progression-free survival (PFS) and cancer-specific survival (CSS). METHODS We retrospectively evaluated 206 high-risk prostate cancer patients treated with RP and analyzed data on age, serum PSA level at diagnosis, biopsy Gleason score (bGS), surgical margin (SM), clinical T stage (cT), extraprostatic extension (EPE), seminal vesicle invasion (SVI), lymph node metastasis (LN), and neoadjuvant therapy. RESULTS An IDC-P component was found in 104 cases. Forty-four patients experienced clinical failure, and 20 patients died of the disease. Patients with IDC-P showed a higher bGS and stage (including cT, EPE, SVI, and LN) than those without IDC-P. In univariate analysis, IDC-P, PSA level, bGS, SM, cT, SVI, LN, and EPE (P < 0.0001) were significantly associated with PFS. IDC-P (P = 0.0004), PSA level (P < 0.0001), SM (P = 0.0013), cT (P = 0.0019), SVI (P = 0.0012), and LN (P = 0.0002) were significantly associated with CSS. In multivariate analysis, IDC-P (P = 0.0038), and cT (P = 0.0001) were significantly associated with PFS. IDC-P (P = 0.0238) and PSA level (P = 0.0112) were significantly associated with CSS. CONCLUSIONS IDC-P in RP specimens was an independent risk factor for PFS and CSS and could predict clinical outcomes.

Abstract
Intraductal carcinoma of the prostate (IDC-P) is characterised by proliferation of malignant secretory cells that markedly expand prostatic ducts and acini. Its morphological features and diagnostic criteria have been refined in recent studies. Its molecular characteristics have also been increasingly elucidated. IDC-P is strongly associated with high grade and high volume invasive prostate cancer and unfavourable clinical outcomes. Therefore, it is critical to recognise and report IDC-P, especially in prostate biopsies where the clinical implications of the diagnosis are greatest. IDC-P has to be distinguished from several other prostate lesions with similar histological appearance. The distinction between IDC-P and high grade prostatic intraepithelial neoplasia is most important as they have drastically different implications for patient management. IDC-P is an uncommon finding in prostate biopsies, and is even rarer as an isolated finding without concomitant prostate cancer in biopsies. However, patients with isolated IDC-P in biopsies are recommended for either definitive treatment or immediate repeat biopsy. This article will review the historical aspect, diagnostic criteria, molecular genetics, and clinical significance of IDC-P.

Abstract
BACKGROUND Intraductal carcinoma (IDC) of prostate is a distinct entity associated with higher Gleason score and poor prognosis. The prognostic significance of large cribriform Gleason pattern 4 (LC) in conjunction with IDC has not been previously investigated. The aim of our study was to determine the impact of IDC and LC on biochemical recurrence-free rate (bRFR) in a contemporary prostatectomy cohort. METHODS Prostate cancers of 246 prostatectomies, median follow-up 130.6 months, were graded with the International Society of Urological Pathology (ISUP) 2005 modified Gleason score (GS) and assessed for the presence of LC and/or IDC. In 57 cases with LC and/or IDC, immunostaining was performed to distinguish LC and IDC. The Kaplan-Meier (KM) method was used to estimate 5-year bRFR probabilities. Cox proportional hazards models were used to generate hazard ratios (HRs) and 95% confidence intervals (CIs). RESULTS Multivariable analysis showed that the presence of any amount of LC or IDC had a highly significant prognostic effect on bRFR (HR 2.98, 95% CI: 1.68-5.28, p=0.0002) after adjusting for GS, surgical margin status and pathological stage. Although IDC alone tended to be associated with a worse prognosis, LC and IDC did not appear to be associated with a difference in bRFR when analysed separately. CONCLUSION We demonstrate that the presence of any amount of LC/IDC is a significant prognostic factor after adjusting for Gleason score and T stage in determining patient outcome and we advocate including the presence of either in routine pathology reporting.

Abstract
There are a variety of morphological patterns and processes that have been implicated in the pathogenesis of prostate cancer. Prostatic intraepithelial neoplasia (PIN), inflammation with or without atrophy, and adenosis (atypical adenomatous hyperplasia) have all been given candidate status as precursor lesions of prostatic adenocarcinoma. Based on decades of research, high grade prostatic intraepithelial neoplasia (HPIN), a proliferative lesion of prostatic secretory cells, has emerged as the most likely morphological pre-invasive lesion involved in the evolution of many but not all prostatic adenocarcinomas. In this manuscript, we briefly discuss other proposed precursors of prostatic adenocarcinoma and then focus on the history, diagnostic criteria and morphology of HPIN. The incidence of HPIN and its relationship to prostate cancer is reviewed. The differential diagnosis of large glandular patterns in the prostate is discussed in depth. Finally, we summarise the recent clinicopathological studies evaluating the clinical significance of HPIN and discuss follow-up strategies in men diagnosed with HPIN.

Abstract
Intraductal carcinoma of the prostate (IDC-P) is defined as a proliferation of prostate adenocarcinoma cells distending and spanning the lumen of pre-existing benign prostatic ducts and acini, with at least focal preservation of basal cells. Studies demonstrate that IDC-P is strongly associated with high-grade (Gleason grades 4/5), large-volume invasive prostate cancers. In addition, recent genetic studies indicate that IDC-P represents intraductal spread of invasive carcinoma, rather than a precursor lesion. Some of the architectural patterns in IDC-P exhibit architectural overlap with one of the main differential diagnoses, high-grade prostatic intraepithelial neoplasia (HGPIN). In these instances, additional diagnostic criteria for IDC-P, including marked nuclear pleomorphism, non-focal comedonecrosis (>1 duct showing comedonecrosis), markedly distended normal ducts/acini, positive nuclear staining for ERG, and cytoplasmic loss of PTEN by immunohistochemistry, can help make the distinction. This distinction between IDC-P and HGPIN is of critical importance because IDC-P has an almost constant association with invasive carcinoma and has negative clinical implications, including shorter relapse-free survival, early biochemical relapse, and metastatic failure rate after radiotherapy. Therefore, IDC-P should be reported in prostate biopsies and radical prostatectomies, regardless of the presence of an invasive component. This article will review the history, diagnostic criteria, molecular genetics, and clinical significance of IDC-P.

Abstract
AIMS Intraductal carcinoma of the prostate (IDC-P) is a distinct clinicopathological entity and is associated with aggressive, high-grade and high-volume prostate carcinoma (PCa). The incidence, clinicopathological characteristics and prognostic significance of IDC-P have not been reported in prostate biopsies (PBx) that surgical pathologists encounter in their daily practice. METHODS AND RESULTS In 1176 prospectively collected PBx, 33 IDC-P cases were identified (2.8%). The mean age of patients with IDC-P was 65 (range 46-79) years and mean serum prostate-specific antigen was 16.2 (range 0.4-105.6) ng/ml. Three (0.26%) IDC-P cases did not have a concomitant invasive PCa. Of 30 cases with concomitant invasive PCa, Gleason score was 7 in 16 (53.3%), 8 in four (13.3%) and 9 in 10 (33.3%) cases. The mean number of biopsy cores involved by PCa was 7.2 (range 1-14). Nine patients were treated with radical prostatectomy. Seminal vesicle invasion was found in four of nine (44%) cases, significantly higher than the risk of 12% predicted by Partin Tables (P = 0.016). CONCLUSIONS This is the first prospective study that has investigated the incidence and prognostic significance of IDC-P diagnosed in PBx encountered in daily practice. It is critical for surgical pathologists to diagnose and report IDC-P in PBx.
