Abstract
BACKGROUND Penile squamous cell carcinoma (PSCC) carries significant morbidity and mortality. Literature is limited regarding prognostic factors, especially prognostic factors for development of metastasis. OBJECTIVES To identify independent prognostic factors associated with poor outcomes, defined as local recurrence (LR), metastasis and disease-specific death (DSD) in clinically node-negative PSCC undergoing local therapy. METHODS Thirty-two-year Retrospective Multicenter Cohort Study of 265 patients with histologically diagnosed PSCC at three tertiary care centres. Predictive models based on patient or tumour characteristics were developed. RESULTS Local recurrence occurred in 56 patients, metastasis in 52 patients and DSD in 40 patients. In multivariable models, the following five factors were independent prognostic factors based on subhazard ratio (SHR): history of balanitis (LR SHR: 2.3; 95% CI 1.2-4.2), poor differentiation (metastasis SHR 1.9; 95% CI 1.0-3.6), invasion into the corpora (metastasis SHR: 3.0; 95% CI 1.5-5.8 and DSD SHR: 4.5; 95% CI 1.7-12.1), perineural invasion (PNI) (metastasis SHR: 2.8; 95% CI 1.4-5.5 and DSD SHR: 3.5; 95% CI, 1.6-7.8) and a history of phimosis (DSD SHR: 2.5; 95% CI 1.2-5.3). The 5-year cumulative incidence of metastasis was higher for tumours with PNI [cumulative incidence function (CIF) = 55%, 95% CI 38-75 vs. CIF 15%, 95% CI 11-22], corporal invasion (CIF: 35%, 95% CI 26-47 vs. 12%, 95% CI 7-19) and poorly differentiated tumours (CIF = 46%, 95% CI 31-64 vs. CIF 15%, 95% CI 11-22). CONCLUSIONS History of balanitis, history of phimosis, PNI, corporal invasion and poor differentiation are independent risk factors associated with poor outcomes. Since poor differentiation and PNI currently constitute only T1b disease, prognostic staging can likely be improved.

Abstract
Malignant penile tumors are of squamous cell origin in more than 95% of cases and the occurrence of a distant metastasis without prior inguinal lymph node metastatic deposits is very rare. This makes inguinal lymph node staging very reliable and of great prognostic significance since undiscovered and untreated inguinal metastases may lead to a fatal clinical course. In lack of a sufficiently accurate noninvasive lymph node staging modality, penile cancer relies on surgical lymph node removal for regional staging. In this respect sentinel node biopsy offers a favourable minimally invasive alternative to prophylactic inguinal lymph node dissection which is associated with significant surgery-related morbidity. Today sentinel node biopsy is widely used in surgical oncology within high volume cancers such as breast cancer and melanoma. In rare cancers sentinel node biopsy is also emerging as a minimal invasive staging tool in patients with no obvious lymph node involvement. At several specialized units across Europe sentinel node biopsy has been practiced by dedicated specialist within vulva and penile cancer for more than two decades. In fact, the rare disease penile cancer was a model entity for development of the original sentinel node concept as early as the 1970'es due to work by the Paraguayan penile cancer pioneer, Cabañas, the sentinel node concept was subsequently successfully adapted in breast cancer and melanoma. This turned out mutually beneficial since the sequential development of sentinel node biopsy in penile cancer in the 1990s eventually adopted new insights and added conceptual details from the experiences harvested in the broader clinical application possible in these high-volume diseases. The prerequisite to conceptualising the sentinel node approach was the gradual anatomical and functional understanding of the lymphatic system which in western medicine rooted in ancient Greece and gradually increased in details and comprehension with significant contributions from many great notabilities during the last centuries including Hippocrates, Galen, Fallopio, Malpighi, Virchow, Starling, Cabañas, Hodgkin and Horenblas. Sentinel node biopsy in penile cancer is a complex multimodality procedure involving inguinal ultrasonography by radiologists, precise tracer-injection and interpretation of nuclear images by nuclear medicine physicians, radio-tracer- and dye guided open surgical biopsies by urologists and thorough step-sectioning, immunostaining and accurate lymph node specimen analysis by pathologists. This team effort requires well-tested protocols, experience and good collaboration and in rare diseases this calls for centralization of service.

Abstract
BACKGROUND Conflicting data on the prognostic significance of obesity in penile cancer have been presented in recent years. OBJECTIVE The objective of this study was to investigate obesity as a prognostic factor in patients with penile squamous cell carcinoma (pSCC) in a large national Danish cohort. Furthermore we aimed to compare the BMI of pSCC patients to a large age-matched cohort of healthy men. METHODS We evaluated 429 patients with invasive pSCC from a national retrospective penile cancer cohort and defined a body mass index (BMI) at 30 kg/m2 as obese. Furthermore, we considered if a fitted model for BMI and mortality could define a critical BMI tipping point for increasing mortality by the means of BMI categories of 1 kg/m2 width. We compared 29 pSCC patients with reported unintended weight loss at diagnosis to 400 with no reported weight loss. Cox regression with 95% confidence intervals was used for penile cancer-specific survival analysis. The comparison between 325 age-matched pSCC patients and 11,238 healthy men from an existing contemporary health database was done by nonparametric tests. RESULTS There was no difference in cancer specific survival between patients with a BMI below and above 30 kg/m2, cox hazard ratio (HR) 0.74 (0.47-1.18), p = .20, but 37 kg/m2 was a tipping point for increasing mortality, HR = 2.10 (1.06-4.18), p = .035. Unintentional weight loss prior to diagnosis significantly predicted worse cancer specific outcome, cox hazard ratio 6.0 (3.5-10.0), p < 001 and cox hazard ratio adjusted for American Joint Committee of Cancer (AJCC)-stage at 1.8 (1.1-3.1), p = .03. Age-matched pSCC patients had a significantly higher BMI than healthy males, 28.4 ± 5.5 kg/m2 vs. 26.2 ± 3.6 kg/m2, p < .0001 and were more likely to smoke, p < .0001, and report alcohol intakes over 14 units/week, p < .0001. CONCLUSION In this Danish cohort, BMI above 30 kg/m2 at diagnosis does not affect prognosis, but BMI at and above 37 kg/m2 at diagnosis predicts poor prognosis. Unintentional weight loss is a predictor of high stage and poor prognosis. PSCC patients have a significantly higher BMI than age-matched healthy males.

Abstract
Lichen sclerosus (LS), or balanitis xerotica obliterans as it was previously known, is a chronic inflammatory lymphocyte-mediated scarring dermatosis that often affects the preputial skin and glans, leading to phimosis and urethral strictures if left untreated. We present a narrative review of the literature assessing its aetiology and pathogenesis and discuss its links to penile cancer and its medical and surgical management. Possible hypotheses for the development of LS include chronic exposure to trapped urine, leading to changes in the epithelial structure. This is supported by the fact that circumcision is often curative in the early stages of the disease. Although circumcision can be curative, the use of topical steroids is typically the first-line treatment and may preserve the foreskin and forgo the need for circumcision altogether. Patients should be made aware of a possible association with penile cancer. Although the majority of cases can be treated by medical therapy and circumcision, a significant number of patients may also require penile reconstructive procedures.

Abstract
PURPOSE Previous histological studies have shown a variable incidence of genital lichen sclerosus (LS). However, the results of these studies were inconsistent. To overcome the limitation of individual studies, we performed this systematic review to explore the true incidence of LS. METHODS A comprehensive search of Pubmed, Embase, Web of Science and Cochrane Library was performed including cross-referencing independently by two assessors. RESULTS A total of 22 articles published from 1980 to 2017 were included in our study. The proportion of LS in those with phimosis had been described in many literature studies, ranging from 2 to 95%. The actual incidence of LS is thought to be clinically underestimated by as much as 50%. CONCLUSIONS The true incidence of LS in boys is more common than previously realized. LS may be observed in foreskin with or without phimosis. The presence of acquired phimosis may be an aggravating factor in the incidence of LS. The diagnosis LS must be based on biopsy for acquired phimosis because clinical findings underestimated the incidence of LS.

Abstract
Primary penile cancer is a rare disease. Higher incidence rates occur in underdeveloped countries. Many studies have suggested an association between human papillomavirus (HPV) infection and penile cancer. Although HPV can affect the squamous epithelium of the male genitalia similarly to the female genital tract, the association between penile cancer and HPV remains unclear. In the present study, the HPV gene expression was examined in penile cancer tissue using in situ hybridization (ISH). The present study included 41 cases in which penectomy was performed and 3 cases in which tumor resection was performed to treat pathologically-diagnosed penile cancer at Yokohama City University Medical Center, and its 7 affiliated hospitals between April 1990 and March 2010. The penile cancer tissue was subjected to an ISH analysis, and the clinicopathological features and prognosis were investigated. A total of 5/44 cases (11.4%) showed the expression of high-risk HPV. None of the patients showed the expression of low-risk HPV. The associations between the expression of high-risk HPV, and age, tumor location, tumor size, T stage, pathological differentiation, nuclear grade, Broder's classification, pattern of invasion, Y-K grade, vascular invasion, lymphoid invasion, koilocytosis and lymph-node metastasis were then examined. Patients with a well-differentiated status (P=0.044) and Broder's Grade 1 (P=0.019) showed a significantly lower rate of HPV positivity. The HPV expression was not significantly associated with cancer specific survival (P=0.932). ISH using INFORM HPV III does not detect the HPV genotype, this method is easy to employ and may be useful for the diagnosis of penile cancer tissue, similarly to cervical cancer.

Abstract
INTRODUCTION Circumcision is one of the most widely performed procedures in the world. One of the indications for circumcision is lichen sclerosis (LS). The natural history of LS in children is not as well-documented as in adult patients. Surgeons use the appearance of the foreskin or meatus to predict the diagnosis of LS. Indeed, if the diagnosis of LS is made in childhood, does it change management in the long-term? Pathological analysis of the excised foreskin is routinely done if there is suspicion of LS. Our aim is to assess the concordance between the clinical and pathological diagnosis of suspected LS and to assess the need for sending the foreskin for pathological examination. METHODS We conducted a retrospective chart review of 64 of 420 boys who underwent circumcision in a tertiary children's hospital from June 2005 to June 2014, and who had their foreskin sent for pathology due to the clinical suspicion of LS. Demographics, presenting symptoms, presumed clinical diagnosis, pathological findings, and followup data were collected and analyzed. RESULTS Over the review period, 64 patients underwent circumcision for presumed LS. The mean age of the children was 9.7 years (range 3-16.5). All the children who had circumcision for presumed LS diagnosis were symptomatic. LS was confirmed in 47 of 64 foreskins (73.5%). Balanitis xerotica obliterans (BXO) was clinically suspected in 40 (85%) of the 47 patients. The mean followup was 10 months (range 1-15), with seven recurrences (15%) during that period. The recurrences required revision surgery in two patients and five were managed with steroids only. CONCLUSIONS In our series, the clinical diagnosis correlated with the pathological diagnosis in most cases. A clinical suspicion of LS without routine foreskin pathological assessment will reduces the overall cost to the healthcare system. Appropriate counselling of the patient/parents and their primary caregiver is imperative, as recurrence is common.

Abstract
Background: Previous Brazilian studies have indicated that working in agriculture could lead to an increased risk of penile cancer. The present descriptive study aimed at establishing a possible association between penile cancer and agricultural occupation. Materials and methods: Data on a total of 103 penile cancer patients were obtained from medical records of two reference centres for cancer treatment in the state of Paraíba, Northeast Brazil. Information about sexual behaviour was obtained in interviews for 48 cases. Results: Of 103 patients 38 and 52 were illiterate and had not completed graduation, respectively, and 60 earned less than twice the minimum wage. All together, 72 (70%) worked in agriculture and 39 confirmed involvement in application of agrochemicals. A history of phimosis was noted for 42 (69%) out of 61 patients and 40 (59%) out of 68 ever smoked. Pathological signs of HPV infection were detected in 45 (70%) out of 64 patients. Of the 48 interviewed patients, 27 (56%) confirmed sexual contact with prostitutes and eight (19%) out of 43 had sex with animals. Conclusions: Data confirmed the presence of several risk factors for penile cancer, like phimosis, smoking, HPV infection and promiscuous sexual behaviour. The high number of Brazilian agricultural workers with penile cancer was unexpected if compared with other professional groups. Future studies should focus on this group of men and elucidate possible reasons for their increased risk.

[PMID: 26948526 PMCID: PMC4896157 DOI: 10.1016/j.urology.2016.02.033] [Citation(s) in RCA: 6] [Impact Index Per Article: 0.8] [Reference Citation Analysis] [Abstract] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/13/2016] [Revised: 02/18/2016] [Accepted: 02/20/2016] [Indexed: 10/22/2022]
Abstract
OBJECTIVE To determine the practice patterns of urologists who treat male genitourinary lichen sclerosus (MGU-LS) via a national web-based survey distributed to American Urological Association members. METHODS A 20-question survey was collected from a random sample of American Urological Association members. Respondents answered questions on their practice patterns for MGU-LS diagnosis, treatment of symptomatic urethral stricture disease, surveillance, and follow-up. RESULTS In total, 309 urologists completed the survey. The majority of respondents reported practicing more than 20+ years (37.5%) within an academic (31.7%) or group practice (31.1%) setting. The majority of respondents saw 3-5 men with MGU-LS per year (32.7%). The most common locations of MGU-LS involvement included the glans penis (66.2%), foreskin (26.3%), and/or the urethra (5.8%). Respondent first-line treatment for urethral stricture disease was direct visual internal urethrotomy (26.6%) and second-line treatment was referral to subspecialist (38.4%). After controlling for the number of patients evaluated with MGU-LS per year, those with reconstructive training were more likely to perform a primary urethroplasty for men with symptomatic urethral stricture disease (adjusted odds ratio 13.1, 95% confidence interval 5.1-33.8, P < .001). They were also more likely to counsel men on the associated penile cancer risks (adjusted odds ratio 4.6, 95% confidence interval 1.7-12.5, P < .01). CONCLUSION Reconstructive urologists evaluate the most number of patients with MGU-LS and are more likely to perform primary urethroplasty for urethral stricture disease. Men with MGU-LS should be referred to a reconstructive urologist to understand the full gamut of treatment options.

Abstract
Purpose Lichen sclerosus (LS) in men is poorly understood. Though uncommon, it is often severe and leads to repeated surgical interventions and deterioration in quality of life. We highlight variability in disease presentation, diagnosis, and patient factors in male LS patients evaluated at a tertiary care center. Materials and Methods We retrospectively reviewed charts of male patients presenting to our reconstructive urology clinic with clinical or pathologic diagnosis of LS between 2004 and 2014. Relevant clinical and demographic information was abstracted and descriptive statistics calculated. Subgroup comparisons were made based on body mass index (BMI), urethral stricture, and pathologic confirmation of disease. Results We identified 94 patients with clinical diagnosis of LS. Seventy percent (70%) of patients in this cohort had BMI >30 kg/m2, and average age was 51.5 years. Lower BMI patients were more likely to suffer from urethral stricture disease compared to overweight counterparts (p=0.037). Patients presenting with stricture disease were more likely to be younger (p=0.003). Thirty percent (30%) of this cohort had a pathologic diagnosis of LS. Conclusions Urethral stricture is the most common presentation for men with LS. Many patients endure skin scarring and have numerous comorbidities. Patient profile is diverse, raising the concern that not all patients with clinical diagnosis of LS are suffering from identical disease processes. The rate of pathologic confirmation at a tertiary care institution is alarmingly low. Our findings support a role for increased focus on pathologic confirmation and further delineation of the subtype of disease based on location and clinical manifestations.

Abstract
PURPOSE Lichen sclerosus is a chronic, inflammatory skin condition of the genitalia of unknown origin that accounts for nearly 10% of urethral stricture disease. In this study we determine systemic comorbidities associated with lichen sclerosus in men. MATERIALS AND METHODS We analyzed data from 1,151 men who were enrolled in a multi-institutional prospective urethroplasty outcomes database. Individuals were grouped by stricture etiology, and baseline demographics, medical histories and patient reported outcome measures were retrospectively compared across groups. RESULTS Of the 1,151 men in the database 81 (7.0%) were noted to have lichen sclerosus related urethral stricture disease. Average patient age was 46.06 ± 16.52 years, with those with lichen sclerosus being significantly older than those without lichen sclerosus (51.26 ± 13.84 vs 45.68 ± 16.64, p = 0.0011). Men with lichen sclerosus were more likely to have hypertension, hyperlipidemia and diabetes, and to use tobacco products. Controlling for age, men with lichen sclerosus related urethral stricture disease had a higher body mass index (aOR 1.089, 95% CI 1.050-1.130), and were more likely to have hypertension (aOR 2.028, 1.21-3.41) and be active tobacco users (aOR 2.0, 1.36-3.40). Mean preoperative patient reported outcome measures scores for urinary and sexual function were similar. Controlling for stricture length and location, the adjusted odds of surgical failure were higher for lichen sclerosus related urethral stricture disease (aOR 1.9, 95% CI 0.9-4.2). CONCLUSIONS Lichen sclerosus related urethral stricture disease is associated with chronic systemic diseases. This association may implicate a systemic inflammatory and/or autoimmune pathophysiology. A 2-hit mechanism implicating local and systemic factors for lichen sclerosus related urethral stricture disease development and progression is hypothesized.

Abstract
Lichen sclerosus affecting the male genitalia is a poorly understood but potentially devastating condition. The natural history of the condition is beginning to be understood better with longer follow-up of patients. Recent long-term data suggest that circumcision for lichen sclerosus limited to the prepuce may not be curative as was once thought. In addition, surgical treatments should be followed up for longer periods as recurrences may occur after urethroplasty and perineal urethrostomy.

Abstract
Penile carcinoma is a rare genitourinary malignancy in North America and Europe with highest rates recorded in South America, Africa and Asia. Recent classifications have refined the terminology used in classifying intraepithelial/in situ lesions and additionally newer entities have been recognised in the invasive category. While increasing recognition of a bimodal pathway of penile carcinogenesis has facilitated understanding and classification of these tumours, handling and subtyping of penile malignancies presents a challenge to the reporting pathologist, in part due to their rarity. This article reviews the terminology and classification of in situ and invasive carcinomas and their relationship to human papilloma virus status. In addition, associated non-neoplastic dermatological conditions of relevance and appropriate ancillary investigations will be addressed.

Abstract
Penile squamous cell carcinoma (SCC) is sometimes an aggressive disease that has a variable worldwide incidence, in part due to differing rates of inflammatory and infectious risk factors. In the developed world, penile SCC is a rare malignancy, and most studies therefore originate in less developed countries. The current study was undertaken to examine the morphologic and immunohistochemical features of penile SCC from a region with low disease incidence. Sixty-two complete or partial penectomy specimens from 59 patients were reviewed. Twenty-six patients had metastasis, 3 had recurrent disease, and 7 were dead due to tumor. Most patients were uncircumcised (72%). Twenty-two percent of carcinomas were associated with lichen sclerosis. Perineural invasion was significantly associated with metastasis (P=0.007). Most SCCs (65%) had the usual keratinizing morphology, and these tumors were significantly associated with the differentiated form of intraepithelial lesion (P<0.0001), p53 positivity (P=0.002), cyclin D1 positivity (P=0.007), and EGFR overexpression (P=0.003). Human papilloma virus (HPV)-associated tumors accounted for 27% and were basaloid (8%), warty (10%), mixed (6%), or lymphoepithelioma-like carcinoma (4%) variants. These were significantly associated with p16 expression (P<0.0001) and the undifferentiated form of intraepithelial lesion (P<0.001). Among all SCCs, there was no difference in the immunohistochemical or in situ hybridization profile between primary tumors and metastases. Although penile SCC is rare in the United States, the tumor variants, immunohistochemical profiles, and proportion of HPV-associated tumors are similar to those in less developed countries. Two distinct pathways appear to lead to carcinogenesis; one is related to underlying chronic inflammatory states, involves p53 mutation, cyclin D1 overexpression, and culminates in classic keratinizing SCC. The other pathway involves high-risk HPV infection, demonstrates strong p16 expression, and results in SCC with varied, but distinctive morphologies.

Abstract
PURPOSE Lichen sclerosus is a chronic inflammatory genital skin condition that can cause destructive urethral scarring. To our knowledge no prior study has described lichen sclerosus in isolated bulbar urethral stricture segments without progressive disease originating from the penile urethra. We report the incidence of lichen sclerosus in isolated bulbar urethral stricture segments. MATERIALS AND METHODS We retrospectively reviewed the records of 70 patients after urethroplasty for isolated bulbar stricture disease was performed from 2007 to 2013. Stricture specimens were re-reviewed by a single uropathologist. Cases were evaluated using common histological features of lichen sclerosus, including hyperkeratosis or epithelial atrophy, basal cell vacuolar degeneration, lichenoid lymphocytic infiltrate and superepithelial sclerosis. RESULTS Average patient age was 46.5 years (range 19 to 77) and average stricture length was 3.5 cm (range 1 to 7). Of the patients 51 (73.0%) underwent excision and primary anastomosis, and 19 (27.1%) underwent buccal mucosal onlay. In 6 patients (8.6%) stricture recurred during a median followup of 22 months (IQR 14, 44). Three of those patients had lichen sclerosus. Initial pathology assessment revealed lichen sclerosus in 5 patients (7.1%, 95% CI 1.0-13.3). On re-review of specimens using pathology criteria specific to lichen sclerosus 31 patients (44.3%, 95% CI 32.4-56.2) showed pathology findings highly suggestive of (13) or diagnostic for (18) lichen sclerosus (p = 0.0001). On pathological re-review lichen sclerosus was associated with recurrent stricture. CONCLUSIONS On re-review of surgical specimens we noted a significant incidence of lichen sclerosus in isolated bulbar strictures in men undergoing urethroplasty. The incidence of lichen sclerosus may be higher than reported in isolated bulbar urethral segments without evidence of distal to proximal progressive urethral disease.
