Abstract
The landscape of squamous cell carcinoma of the penis (SCC-P) has undergone a significant transformation since the new World Health Organization classification of genitourinary cancers and recent European Association of Urology/American Association of Clinical Oncology guidelines. These changes emphasize the necessity to categorize SCC-P into 2 groups based on its association with human papillomavirus (HPV) infection. This shift has major implications, considering that prior knowledge was derived from a mix of both groups. Given the distinct prognosis, treatment options, and staging systems observed for HPV-associated tumors in other body areas, the question now arises: will similar patterns emerge for SCC-P?

Abstract
BACKGROUND While cervical cancer incidence rates (IR) in the United States have dropped in the last 20 years, non-cervical human papillomavirus (HPV) associated cancers increased. Many people in Texas (TX) live in medically underserved areas and have higher risk of developing HPV-associated cancers. Since previous studies of these regions focused on cervical cancer, we included other HPV-associated cancers in our analysis of IR in East TX and the TX-Mexico Border compared to other TX regions. METHODS Cancer data from 2006 to 2019 were obtained from the TX Cancer Registry. Cases of HPV-associated cervical, vaginal, vulvar, penile, anal, and oropharyngeal cancers and corresponding patient-level demographic data were included. We calculated IR per 100,000 and drew heat maps to visualize cancer IR by county. To control potential confounders, we added county-level risk factors: rates for smoking, excessive drinking, obesity, STIs, primary care provider availability and dentist availability, from the County Health Rankings and Roadmaps program. We reported IRs by region and time and estimated unadjusted and adjusted risk ratio (RR) for association of each type of cancer and region. Lastly, we created adjusted models for each cancer by period to see time trends of regional differences. RESULTS Risk of anal, cervical, and oropharyngeal cancer was lower at parts of the Border than in the rest of TX in the adjusted model. We also observed increasing anal and oropharyngeal cancer risk and decreasing cervical and vaginal cancer risk over time. CONCLUSION Patient sociodemographics, behavioral risk factors, and access to care may contribute to some observed differences in cancer IR across regions. This indicates that targeted prevention efforts towards these regions, especially in low socioeconomic status communities, may benefit future generations.

Comparing the safety and effectiveness of minimally invasive surgery and open inguinal lymph node dissection in penile cancer: A systematic review and meta-analysis. EUROPEAN JOURNAL OF SURGICAL ONCOLOGY 2024; 50:108553. [PMID: 39059191 DOI: 10.1016/j.ejso.2024.108553] [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: 01/07/2024] [Revised: 06/04/2024] [Accepted: 07/18/2024] [Indexed: 07/28/2024]
Abstract
OBJECTIVE To compare the safety and effectiveness of minimally invasive surgery (MIS) with open inguinal lymph node dissection (O-ILND) in penile cancer. METHODS We performed a systematic reviews and cumulative meta-analyses of primary results of interest according to PRISMA criteria, and quality assessment followed AMSTAR. The system searched five databases, including Zhiwang, Embase, PubMed, Cochrane Library and Web of Science. The search period ranged was from database creation until September 2023. The statistical analysis software used Stata16. RESULTS A total of 16 studies, including 898 patients. Compared to O-ILND, MIS is superior in length of stay (WMD = -2.96, 95%CI [-4.38, -1.54], P < 0.05), drainage time (WMD = -3.24, 95%CI [-4.70, -1.78], P < 0.05) and estimated blood loss (WMD = -35.70, 95%CI [-46.27, -25.14], P < 0.05), while operation time, recurrence rate and 5-year overall survival rate are the same. The number of lymph nodes dissection between the two groups are not statistically significant. Subgroup analyses found that there are more lymph nodes dissection in robotic-assisted inguinal lymph nodes dissection (WMD = 0.50, 95%CI [0.20, 0.80], P < 0.05). The overall complication rate of MIS was lower (OR = 0.26, 95%CI [0.09, 0.70], P < 0.05). CONCLUSION Minimally invasive inguinal lymph nodes dissection appears to be a better option for penile cancer cases. But more large samples and multicenter studies are needed to further confirm.

Cancer Med 2024; 13:e7111. [PMID: 38566587 PMCID: PMC10988236 DOI: 10.1002/cam4.7111] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/04/2024] [Revised: 03/01/2024] [Accepted: 03/04/2024] [Indexed: 04/04/2024] Open
Abstract
OBJECTIVE The primary aim of this study was to create a nomogram for predicting survival outcomes in penile cancer patients, utilizing data from the Surveillance, Epidemiology, and End Results (SEER) and a Chinese organization. METHODS Our study involved a cohort of 5744 patients diagnosed with penile cancer from the SEER database, spanning from 2004 to 2019. In addition, 103 patients with penile cancer from Sun Yat-sen Memorial Hospital of Sun Yat-sen University were included during the same period. Based on the results of regression analysis, a nomogram is constructed and validated internally and externally. The predictive performance of the model was evaluated by concordance index (c-index), area under the curve, decision curve analysis, and calibration curve, in internal and external datasets. Finally, the prediction efficiency is compared with the TNM staging model. RESULTS A total of 3154 penile patients were randomly divided into the training group and the internal validation group at a ratio of 2:1. Nine independent risk factors were identified, including age, race, marital status, tumor grade, histology, TNM stage, and the surgical approach. Based on these factors, a nomogram was constructed to predict OS. The nomogram demonstrated relatively better consistency, predictive accuracy, and clinical relevance, with a c-index over 0.73 (in the training cohort, the validation cohort, and externally validation cohort.) These evaluation indexes are far better than the TNM staging system. CONCLUSION Penile cancer, often overlooked in research, has lacked detailed investigative focus and guidelines. This study stands as the first to validate penile cancer prognosis using extensive data from the SEER database, supplemented by data from our own institution. Our findings equip surgeons with an essential tool to predict the prognosis of penile cancer better suited than TNM, thereby enhancing clinical decision-making processes.

Rural-urban disparity in cancer burden and care: findings from an Indian cancer registry. BMC Cancer 2024; 24:308. [PMID: 38448839 PMCID: PMC10916062 DOI: 10.1186/s12885-024-12041-y] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/14/2023] [Accepted: 02/22/2024] [Indexed: 03/08/2024] Open
Abstract
BACKGROUND Cancer incidence and mortality vary across the globe, with nearly two-thirds of cancer-related deaths occurring in low- and middle-income countries. The rural-urban disparity in socio-demographic, behavioural, and lifestyle-related factors, as well as in access to cancer care, is one of the contributing factors. Population-based cancer registries serve as a measure for understanding the burden of cancer. We aimed to evaluate the rural-urban disparity in cancer burden and care of patients registered by an Indian population-based cancer registry. METHODS This study collected data from Varanasi, Uttar Pradesh, India, between 2017 and 2019. Sex and site-specific age-standardised rates for incidence and mortality per 100,000 population were calculated. Rural-urban disparities in cancer incidence and mortality were estimated through rate differences and standardised rate ratios (with 95% confidence intervals). Univariable and multivariable regressions were applied to determine any significant differences in socio-demographic and cancer-related variables according to place of residence (rural/urban). Crude and adjusted odds ratios with 95% confidence intervals were calculated. RESULTS 6721 cancer patients were registered during the study duration. Urban patients were older and had better literacy and socioeconomic levels, while rural patients had higher odds of having unskilled or semi-skilled professions. Diagnostic and clinical confirmation for cancer was significantly higher in urban patients, while verbal autopsy-based confirmation was higher in rural patients. Rural patients were more likely to receive palliative or alternative systems of medicine, and urban patients had higher chances of treatment completion. Significantly higher incidence and mortality were observed for oral cancer among urban men and for cervical cancer among rural women. Despite the higher incidence of breast cancer in urban women, significantly higher mortality was observed in rural women. CONCLUSIONS Low- and middle-income countries are facing dual challenges for cancer control and prevention. Their urban populations experience unhealthy lifestyles, while their rural populations lack healthcare accessibility. The distinctness in cancer burden and pattern calls for a re-evaluation of cancer control strategies that are tailor-made with an understanding of urban-rural disparities. Context-specific interventional programmes targeting risk-factor modifications, cancer awareness, early detection, and accessibility to diagnosis and care are essential.

Abstract
OBJECTIVES To examine the global disease burden and country-specific trends of penile cancer incidence by age group and investigate its associations with several factors. MATERIALS AND METHODS The Global Cancer Observatory database was interrogated for penile cancer incidence. The 10-year cancer incidence rates were collected from the Cancer Incidence in Five Continents Plus. The country-specific data were extracted from the World Health Organization Global Health Observatory and Global Burden of Disease databases for conducting risk factors analysis. The penile cancer incidence was presented using age-standardised rates. Its associations with various factors were examined by linear regression, while the incidence trend was estimated using joinpoint regression and presented as average annual percentage change with 95% confidence intervals in different age groups. RESULTS There were an estimated 36 068 new cases of penile cancer in 2020. There was a considerable geographical disparity in the disease burden of penile cancer, with South America reporting the highest incidence. Overall, alcohol drinking, human immunodeficiency virus (HIV) infection, and unsafe sex were positively associated with a higher penile cancer incidence, while circumcision was found to be a protective factor. There has been a mixed trend in penile cancer incidence overall, but an increasing trend was found among younger males. CONCLUSIONS There was a global variation in the penile cancer burden associated with prevalence of alcohol drinking, HIV infection, unsafe sex, and circumcision. The increasing penile cancer incidence in the younger population is worrying and calls for early detection and preventive interventions.

Abstract
PURPOSE This study aims to analyze the trends in mortality rates from penile cancer (PeC) and the treatment modalities adopted in Brazil over recent years. MATERIALS AND METHODS Death records for PeC cases (International Classification of Diseases, version 10 C60) and treatment modalities were extracted from the DATASUS database. A joinpoint regression analysis was conducted to examine the data. RESULTS A total of 7,848 deaths due to PeC were recorded in Brazil between 1996 and 2020. Increasing mortality trends were observed, with an average annual percentage change (AAPC) of 0.91 (0.6-1.2; P < .001). The North and Northeast regions had the highest age-standardized mortality rates (ASMRs) and AAPCs. From 2008 to 2020, the ASMR in the Northeast region remained stable, whereas the North region surpassed it. The Southeast region exhibited a significant downward trend, with an AAPC of -0.91 (-1.3 to -0.5; P < .001). Penile biopsies declined and were more frequent in the southeastern region. A total of 8,498 penile amputations were performed, with 39.4% and 29.1% conducted in the Southeast and Northeast regions, respectively. CONCLUSION Brazil has experienced increasing mortality trends in PeC over the past 2 decades. Low schooling, married, and young men from the North or Northeast regions represent the majority of deaths. Urgent efforts are needed to enhance the diagnosis and treatment of PeC to prevent and reduce mortality rates in the country.

Abstract
PURPOSE To review the evidence for radiotherapy in the management of primary penile cancer, either as brachytherapy or external beam radiation, and the role of external beam radiotherapy in node positive penile cancer. METHODS English language literature was reviewed for the past 3 decades. As penile cancer is uncommon in developed nations, high quality evidence to guide management is limited. Single institution reports often span decades during which time staging systems and treatments have evolved, reducing their relevance to current practice. Successful clinical trials require collaboration not only among disciplines but also among multiple institutions and nations. RESULTS Radiotherapy is a definitive organ-preserving option for T1-T2 penile cancers. Interstitial brachytherapy is associated with penile preservation in 85% of men at 5 years, maintained in 70% by 10 years. Results of external radiotherapy are not quite as promising but nonetheless 60% of men will have an intact penis at 5 years. Inguino-pelvic external radiotherapy has been reported to increase overall survival when delivered as adjuvant treatment for men with pN3 groin but pN0 pelvic nodes, and improve disease specific survival for those with involved pelvic nodes. InPACT (ECOG-ACRIN_8134) is investigating the role of inguino-pelvic chemo-radiotherapy for men with pN3 inguinal nodes but imaging negative pelvic nodes. CONCLUSIONS Radiotherapy has a well-defined role to play in treatment of squamous cell cancers of other sites, such as vulva, anal canal, uterine cervix and head and neck malignancies. Emerging data support the incorporation of radiotherapy into treatment paradigms for penile cancer.

Abstract
OBJECTIVE to trace the clinical and epidemiological profile of penile cancer in Rio Grande do Norte/Brazil and relate them to data published in the literature. METHODS a cross-sectional study was conducted with 94 patients diagnosed with penile cancer in 2011-2018, treated at the Liga Norte Riograndense Contra o Cancer. RESULTS all patients were diagnosed with squamous cell carcinoma, mainly aged over 50 years, from the states interior, brown, illiterate, or with incomplete primary education. At diagnosis, 68% of patients were classified as having tumors =T2, and 30% had lymph node involvement. Distant metastases were detected in 2.1% of patients at diagnosis. Most patients received the diagnosis in the initial phase of the disease, but 20.2% were diagnosed in stage IV. Partial penectomy was the most performed surgery, and 10% of patients relapsed, mainly in the lymph nodes (87.5%). The mean follow-up of the patients was 18 months, with an estimated overall survival at five years of 59.1%. However, 25% of patients were followed up for up to 3 months, losing follow-up. CONCLUSION the State of Rio Grande do Norte has a high incidence of penile cancer with a high frequency of locally advanced tumors at diagnosis and in younger patients younger than 50. Furthermore, socioeconomic factors interfere with early diagnosis and hinder access to specialized services.

Epidemiology, Diagnosis and Management of Penile Cancer: Results from the Spanish National Registry of Penile Cancer. Cancers (Basel) 2023; 15:cancers15030616. [PMID: 36765574 PMCID: PMC9913503 DOI: 10.3390/cancers15030616] [Citation(s) in RCA: 1] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/22/2022] [Revised: 01/11/2023] [Accepted: 01/17/2023] [Indexed: 01/20/2023] Open
Abstract
INTRODUCTION Penile cancer (PC) is a rare malignancy with an overall incidence in Europe of 1/100,000 males/year. In Europe, few studies report the epidemiology, risk factors, clinical presentation, and treatment of PC. The aim of this study is to present an updated outlook on the aforementioned factors of PC in Spain. MATERIALS AND METHODS A multicentric, retrospective, observational epidemiological study was designed, and patients with a new diagnosis of PC in 2015 were included. Patients were anonymously identified from the Register of Specialized Care Activity of the Ministry of Health of Spain. All Spanish hospitals recruiting patients in 2015 were invited to participate in the present study. We have followed a descriptive narration of the observed data. Continuous and categorical data were reported by median (p25th-p75th range) and absolute and relative frequencies, respectively. The incidence map shows differences between Spanish regions. RESULTS The incidence of PC in Spain in 2015 was 2.55/100,000 males per year. A total of 586 patients were identified, and 228 patients from 61 hospitals were included in the analysis. A total of 54/61 (88.5%) centers reported ≤ 5 new cases. The patients accessed the urologist for visually-assessed penile lesions (60.5%), mainly localized in the glans (63.6%). Local hygiene, smoking habits, sexual habits, HPV exposure, and history of penile lesions were reported in 48.2%, 59.6%, 25%, 13.2%, and 69.7%. HPV-positive lesions were 18.1% (28.6% HPV-16). The majority of PC was squamous carcinoma (95.2%). PC was ≥cT2 in 45.2% (103/228) cases. At final pathology, PC was ≥pT2 in 51% of patients and ≥pN1 in 17% of cases. The most common local treatment was partial penectomy (46.9% cases). A total of 47/55 (85.5%) inguinal lymphadenectomies were open. Patients with ≥pN1 disease were treated with chemotherapy in 12/39 (40.8%) of cases. CONCLUSIONS PC incidence is relatively high in Spain compared to other European countries. The risk factors for PC are usually misreported. The diagnosis and management of PC are suboptimal, encouraging the identification of referral centers for PC management.

Abstract
Penile squamous cell carcinoma is a rare disease entity with poor overall survival in an advanced stage. Few studies have investigated the role of immunotherapy in advanced penile squamous cell carcinoma. Herein, we report a case of stage IV unresectable penile squamous cell carcinoma presenting with anal bleeding and urethra obstruction who responded dramatically to combination therapy of durvalumab and cisplatin-based chemotherapy. The patient had HPV-positive penile squamous cell carcinoma, cT3N3M0, with concomitant anus squamous cell carcinoma. After 2 months of the combination treatment, almost all bulky inguinal lymph nodes shrank, and the main tumor of the anus and penis responded completely. A durable response was seen 16 months after initiating the combination therapy. This case report highlights the potential role of the combination of immunotherapy and chemotherapy in patients with advanced penile cancer. The promising results of this combination resulted in the conversion of unresectable disease to a potentially curable disease.

Abstract
Penile cancer is a rare malignancy and usually refers to penile squamous cell carcinoma (PSCC), which accounts for more than 95% of all penile malignancies. Although organ-sparing surgery is an effective treatment for early-stage PSCC, surgical intervention alone is often not curative for advanced PSCC with metastases to the inguinal and/or pelvic lymph nodes; thus, systemic therapy is required (usually platinum-based chemotherapy and surgery combined). However, chemotherapy for PSCC has proven to be of limited efficacy and is often accompanied by high toxicity, and patients with advanced PSCC usually have poor prognosis. The limited treatment options and poor prognosis indicate the unmet need for advanced PSCC. Immune-based therapies have been approved for a variety of genitourinary and squamous cell carcinomas but are rarely reported in PSCC. To date, several studies have reported high expression of PDL1 in PSCC, supporting the potential application of immune checkpoint inhibitors in PSCC. In addition, human papillomavirus (HPV) infection is highly prevalent in PSCC and plays a key role in the carcinogenesis of HPV-positive PSCC, suggesting that therapeutic HPV vaccine may also be a potential treatment modality. Moreover, adoptive T cell therapy (ATC) has also shown efficacy in treating advanced penile cancer in some early clinical trials. The development of new therapeutics relies on understanding the underlying biological mechanisms and processes of tumor initiation, progression and metastasis. Therefore, based on the interest, we reviewed the tumor immune microenvironment and the emerging immunotherapy for penile cancer.

Evaluation of APOBEC3 expression as prognostic marker in squamous cell carcinoma of the penis. Sci Rep 2022; 12:12911.

Abstract
Squamous cell carcinoma of the penis (PSC) is a rare disease with limited information on the molecular events leading to malignant transformation. In a third of PSC cases, presence of human papilloma virus (HPV) is found. The APOBEC3 family of proteins is known to play a significant role in defense against HPV infection, but their role in PSC is largely unknown. In this study, we aim to assess mRNA expression levels of APOBEC3 family members in HPV+ and HPV− PSC to get insight into their association with clinicopathological features and to evaluate their prognostic impact. Expression levels of six APOBEC3 family members in tissue from 50 patients with PSC were determined by RT-PCR and correlated with clinical and histopathological features. Lower expression of APOBEC3A, APOBEC3B, and APOBEC3C was observed in advanced PSC stages. Except for APOBEC3D, HPV+ samples showed higher expression of APOBEC3s compared to HPV− samples. In univariate analyses, APOBEC3A and APOBEC3C expression tended to be associated with disease-free survival and APOBEC3A expression with overall survival; however, multivariable analyses failed to confirm these associations with outcome. More extensive external validation and functional laboratory studies are needed to evaluate further their role in PSC development and progression.

Development and Verification of Prognostic Nomogram for Penile Cancer Based on the SEER Database. BIOMED RESEARCH INTERNATIONAL 2022; 2022:8752388. [PMID: 35419456 PMCID: PMC9001101 DOI: 10.1155/2022/8752388] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Subscribe] [Scholar Register] [Received: 11/23/2021] [Revised: 02/28/2022] [Accepted: 03/08/2022] [Indexed: 11/25/2022]
Abstract
Aim We aimed to establish a prognostic nomogram for penile cancer (PC) patients based on the Surveillance, Epidemiology, and End Results Program (SEER) database. Methods Data from 1643 patients between 2010 and 2015 were downloaded and extracted from the SEER database. They were randomly divided into the development group (70%) and the verification group (30%), and then, univariate and multivariate Cox proportional hazards regression, respectively, was used to explore the possible risk factors of PC. The factors significantly related to overall survival (OS) and cancer-specific survival (CSS) were used to establish the nomogram, which was assessed via the concordance index (C-index), receiver operating characteristic (ROC) curve, and calibration curve. An internal validation was conducted to test the accuracy and effectiveness of the nomogram. Kaplan–Meier calculation was used to predict the further OS and CSS status of these patients. Results On multivariate Cox proportional hazards regression, the independent prognostic risk factors associated with OS were age, race, marital status, N/M stage, surgery, surgery of lymph nodes, and histologic type, with a moderate C-index of 0.737 (95% confidence interval (CI): 0.713–0.760) and 0.766 (95% CI: 0.731–0.801) in the development and verification groups, respectively. The areas under the ROC (AUC) of 3- and 5-year OS were 0.749 and 0.770, respectively. While marital status, N/M stage, surgery, surgery of lymph nodes, and histologic type were significantly linked to PC patients' CSS, which have better C-index of 0.802 (95% confidence interval (CI): 0.771–0.833) and 0.82 (95% CI: 0.775–0.865) in the development and verification groups, and the AUC of 3- and 5-year CSS were 0.766 and 0.787. Both of the survival calibration curves of 3- and 5-year OS and CSS brought out a high consistency. Conclusion Our study produced a satisfactory nomogram revealing the survival of PC patients, which could be helpful for clinicians to assess the situation of PC patients and to implement further treatment.

Abstract
To compare the clinical feasibility and oncological outcome of different surgical techniques for inguinal lymphadenectomy (ILND) in patients suffering from penile cancer. This study included data from 109 cN0-2 patients diagnosed with penile cancer who received ILND. 80 laparoscopic ILND were performed on 40 patients, while 138 open surgeries were performed on 69 patients. Perioperative complications and prognosis were compared between different surgical techniques. Compared with the open surgery group, the laparoscopy group had a shorter hospital stay (8.88 ± 7.86 days vs. 13.94 ± 10.09 days, P = 0.004), and a lower wound healing delay rate (8.75% vs. 22.46%, P = 0.017), but also had longer drainage time (10.91 ± 9.66 vs. 8.70 ± 4.62, P = 0.002). There were no significant differences in terms of other intraoperative parameters, complications, and survival between open and laparoscopic group. Compared with saphenous vein ligated subgroup, preserved subgroup showed no significant reducing of complication rate. There was no significant difference among complication between different open surgery subgroup. Immediate ILND showed no prognostic advantage over delayed ILND regardless of clinical lymph node status. Compared with open surgery, the minimally invasive ILND technique has similar oncological efficiency and a lower complication rate. Saphenous vein preservation has limited value in reducing complications. Delayed lymphadenectomy might be a more reasonable option for ILND.

Abstract
Objective To investigate the predictive factors of lymph node metastasis (LNM) and evaluate the usefulness of prediction nomograms. Methods This study included 300 patients diagnosed with penile squamous cell carcinoma at West China Hospital (WCH) of Sichuan University (Chengdu, China) and 412 cases acquired from the Surveillance, Epidemiology, and End Results (SEER) program. Logistic regression analysis was performed on these cohorts to investigate the predictive factors of LNM. We evaluated a recently developed prediction nomogram for LNM, which was established based on the National Cancer Database (NCDB). Moreover, we developed a novel nomogram using cases from the WCH for the prediction of lymphatic metastasis. Results Logistic analysis identified that younger age at diagnosis, invasion of the penis body, poorer pT stage, cN stage, nuclear grade and the presence of lymph vascular invasion (LVI) were significantly correlated with LNM in WCH cases; however, only race, poorer T stage and cN stage were significantly associated with LNM among the cases from the SEER. Multivariate analysis demonstrated that younger age, poorer T stage, cN stage and nuclear grade were independent predictors of LNM. Receiver operating characteristic curve analysis of WCH cases showed that the tumor T stage 8th edition has better area under the curve than 7th stage (0.672 vs 0.636, respectively). Moreover, well AUC was seen in external validation of NCDB nomogram in WCH cohorts and SEER series (0.833 vs 0.795). The new nomogram included the aforementioned independent predictors and the bootstrap-corrected concordance was 0.876. Conclusion Younger diagnose age, poorer pT stage, cN stage, nuclear grade and LVI were the most important predictors of LNM in patients with penile cancer. 8th T stage performed better than 7th version in predicting LNM. NCDB nomogram has some application values in both WCH and SEER cases, and our novel model further improved the predictive accuracy.

Abstract
Objectives To develop an international consensus on managing penile cancer patients during the COVID-19 acute waves. A major concern for patients with penile cancer during the coronavirus disease 2019 (COVID-19) pandemic is how the enforced safety measures will affect their disease management. Delays in diagnosis and treatment initiation may have an impact on the extent of the primary lesion as well as the cancer-specific survival because of the development and progression of inguinal lymph node metastases. Materials and methods A review of the COVID-19 literature was conducted in conjunction with analysis of current international guidelines on the management of penile cancer. Results were presented to an international panel of experts on penile cancer and infection control by a virtual accelerated Delphi process using 4 survey rounds. Consensus opinion was defined as an agreement of ≥80%, which was used to reconfigure management pathways for penile cancer. Results Limited evidence is available for delaying penile cancer management. The consensus rate of agreement was 100% that penile cancer pathways should be reconfigured, and measures should be developed to prevent perioperative nosocomial transmission of COVID-19. The panel also reached a consensus on several statements aimed at reconfiguring the management of penile cancer patients during the COVID-19 pandemic. Conclusions The international consensus panel proposed a framework for the diagnostic and invasive therapeutic procedures for penile cancer within a low-risk environment for COVID-19.

Abstract
Penile cancer is a very rare malignancy and it is usually identified as a nodule or an ulceration. We report a case of locally advanced penile cancer presented as a urethral stricture and recurrent scrotal abscess. The patient had been treating for obstructive voiding symptoms and septic condition for 5 months. Because of persistent symptoms, a drainage of the abscess was performed and the histopathological examination showed infiltrating moderately differentiated squamous cell carcinoma of penis. He underwent a surgical Emasculation followed by the administration of a combination of chemotherapy (paclitaxel, ifosfamide, and cisplatin). We highlight the importance of including penile cancer in the differential diagnosis of scrotal abscess and urethral stricture. A multimodal approach is an effective strategy to manage the disease.

Abstract
PURPOSE The aim of this work is to review and synthesize the existing evidence and recommendations regarding to the therapeutic and surgical indications as well as monitoring of patients with Penile Cancer in COVID-19 era and to propose an action protocol to facilitate decision-making. MATERIAL AND METHODS A non-systematic review of the literature regarding the management of penile cancer during the COVID-19 pandemic was performed until April 30, 2020. We propose our recommendations based on this evidence. RESULTS Penile cancer is an uncommon but aggressive disease. Prognosis is determined by several characteristics, being the most important the presence of lymph nodes, in which case, treatment should not be delayed. For these reasons, an initial evaluation is mandatory. Priority classifications, based on the oncological outcomes when treatment is delayed, have been made in order to separate deferrable disease from the one that needs high priority treatment. In penile cancer with low risk of progression, surgical treatment can be delayed, but other options must be considered, like topical treatment or laser therapy. In cases with intermediate risk of progression, surgical treatment may be delayed up to three months, but we must consider radiation therapy and brachytherapy as effective options. When feasible, follow-up should by telemonitoring. CONCLUSIONS In the COVID-19 era, initial evaluation of the patient is mandatory. Histological diagnosis with local staging is necessary before offering any therapeutic option. In case of superficial non-invasive disease, topical treatment is effective in absence of lymph node involvement. In selected patients, radiotherapy is an organ-preserving approach with good results. Non-deferrable surgical treatment must be performed by an experienced surgeon and as an outpatient procedure when possible. When indicated, iLND should not be delayed since it is decisive for patient survival. Follow-up should be by telemonitoring.

Abstract
Purpose This study aimed to establish a nomogram to predict the long‐term overall survival (OS) for patients with penile squamous cell carcinoma (PSCC). Method The PSCC patients receiving regional lymph node dissection (RLND) were enrolled from the Surveillance, Epidemiology, and End Results (SEER) database between 2004 and 2015. The dataset of all eligible patients were used to develop the predictive model. The significant independent predictors were identified through Cox regression modeling based on the Bayesian information criterion and then incorporated into a nomogram to predicted 1‐, 3‐, and 5‐year OS. Internal validation was performed using the bootstrap resampling method. The model performance was evaluated using Harrell's concordance index (C‐index), calibration plots, integrated discrimination improvement (IDI), net reclassification improvement (NRI), and decision curve analysis (DCA). Results Totally, 384 eligible PSCC patients were enrolled from the SEER database. A nomogram for OS prediction was developed, in which three clinical variables significantly associated with OS were integrated, including age, N classification, and log odds of positive lymph nodes (LODDS). The C‐index of the nomogram (0.746, 95% CI: 0.702‐0.790) was significantly higher than that of the American Joint Committee on Cancer (AJCC) staging system (0.692, 95% CI: 0.646‐0.738, P = .020). The bootstrap optimism‐corrected C‐index for the nomogram was 0.739 (95% CI: 0.690‐0.784). The bias‐corrected calibration plots showed the predicted risks were in good accordance with the actual risks. The results of NRI, IDI, and DCA exhibited superior predictive capability and higher clinical use of the nomogram compared with the AJCC staging system. Conclusion We successfully constructed a simple and reliable nomogram for OS prediction among PSCC patients receiving RLND, which would be beneficial to clinical trial design, patient counseling, and therapeutic modality selection.

Abstract
Human papillomavirus (HPV) infection appears to play an important role in the development of penile cancer (PeCa), but their relationship remains unclear. Therefore, we performed a systematic review and meta-analysis to elucidate their relationship. We systematically searched Embase, PubMed, Cochrane Library, and Web of Science for case-control studies and cross-sectional studies using polymerase chain reaction (PCR) technology on formalin-fixed paraffin-embedded (FFPE) or paraffin-embedded (PE) PeCa tissues to detect HPV (published between January 1, 2007, and December 29, 2017; no language restrictions). Twenty-two studies were identified, and 1664 cases were available for analysis. The combined HPV infectious risk of PeCa is 51.0% (95% confidence interval [CI]: 43.0%–60.0%). The three most common subtypes of HPV were HPV16 (28.5%), HPV18 (2.3%), and HPV6 (2.3%). The virus was relevantly associated with basaloid (85.5%, 95% CI: 77.2%–93.8%) and warty (50.0%, 95% CI: 35.2%–64.8%) carcinomas. The invasiveness of PeCa was not associated with HPV (χ2 = 0.181, df = 1, P < 0.671). HPV infection in PeCa tended to be moderately differentiated (54.4%, 95% CI: 47.7%–61.1%). This study found that almost half of PeCa patients are associated with HPV. The most commonly associated genotype is HPV16, but several other genotypes were also detected. In addition to types 6 and 11, other single low-risk HPV infections have been found to contribute to PeCa to a lesser degree. HPV-positive tumors tend to exhibit warty and/or basaloid features, corresponding to a moderate histological grade. The role of HPV in PeCa should be revisited to provide evidence for the development of PeCa in the presence of HPV infection.

Abstract
Background Surgery is the standard treatment for organ-restricted penile cancer, but it is also a disfiguring procedure that can profoundly affect quality of life. Using a survey, in this study we assessed the effect of different surgical invasiveness on satisfaction in selected life domains of patients who underwent penile-sparing surgery and partial penectomy. METHODS Forty patients who underwent penile-sparing surgery (n=13) or partial penectomy (n=27) were enrolled in the study. The response rate was 71%. Information was obtained after surgery on sexuality, self-esteem, masculinity and partner relationships using the International Index of Erectile Function, the Self-Esteem Scale and the Conformity to Masculinity Norms Inventory questionnaires. We evaluated the effect of primary surgery type on selected domains of quality of life and correlations between study variables after surgery. RESULTS High self-esteem, satisfactory erectile function and masculinity results in both groups were comparable to those in the published literature. Men who underwent less disfiguring treatment had a significantly higher sense of masculinity than those who underwent partial penectomy (P=0.05). No significant differences were observed in erectile dysfunction and self-esteem. The level of aggressiveness of a surgical procedure was a predictor of sense of masculinity (P=0.01), but was not associated with self-esteem and sexual dysfunction (P=0.28 and P=0.55 respectively); 83% of patients were able to satisfactorily maintain partner relationships. CONCLUSIONS Disfiguring treatments for penile cancer significantly interfere with the sense of masculinity, but sexual functioning and self-esteem do not differ according to the type of surgical procedure. Most men maintained stable partner relationships after surgery, regardless of surgery type.

Abstract
To determine the epidemiological, histopathological, and clinical characteristics of patients diagnosed with penile cancer in the Brazilian state of Maranhão, the region with the highest incidence worldwide. One hundred and sixteen penile cancer patients were interviewed from July 2016 to October 2018. The majority of patients lived in a rural area (57%), worked in farming (58%), had a low level of schooling or no schooling (90%), and were married or in a stable relationship (74%). The mean age was 60.4 ± 16.51 years (range, 23–93 years). Phimosis (66%), poor/moderate genital hygiene (73%), history of sexually transmitted infections (55%), and zoophilia (60%) were found in the majority of patients. Most patients had their first sexual encounter at 16.2 ± 2.8 years (range, 10–25 years), and 75% had >6 sexual partners. The most common initial symptom was pruritus (37%), and most patients waited to seek treatment (average time to treatment, 18.9 months; range, 2–84 months). Human papillomavirus (HPV)-related histologies were observed in 62% of patients. Most patients had histological grades II or III (87%), stage ≥T2 disease (84%), and lymphadenopathy at admission (42%). Penectomy was performed in 96% of patients. The population with penile cancer in the region of highest incidence in the world is marked by low socioeconomic status, high prevalence of HPV infection, and phimosis. The delay in seeking treatment is related to a very high rate of advanced cancer and aggressive surgical treatment. The high prevalence of young patients was also a striking feature.

Abstract
Since the seminal study of Hart and Helwig in 1975, there are few detailed pathological studies of lichen sclerosus (LS). The aims of this study were to provide a detailed histopathological description of penile LS, as well as to explore its relationship with penile intraepithelial neoplasia (PeIN) or invasive carcinoma. We evaluated 200 patients and designed a topographical approach for the histological evaluation focusing in alterations of the following anatomical layers: squamous epithelium, lamina propria, dartos, and corpus spongiosum. We documented the quantity and topographical location of stromal lymphocytes. The prevalent lesions found were epithelial hyperplasia, atrophy, PeIN, basal cell vacuolization, lamina propria sclerosis, and variable patterns of lymphocytic infiltration. Various unique patterns of stromal sclerosis were described: perivascular, globular, linear, and solid fibrosis/hyalinization; any of them were found to be diagnostic for LS. The variation in the topography and density of lymphocytes was determinant for the identification of LS morphological variants: lichenoid, band-like, lymphocytic depleted, and mixed. A major finding was the identification of the variant designated as lymphocytic depleted LS, which we considered as the morphological prototype of LS associated with penile neoplasia. The detailed description of this complex lesion presented in this study may help pathologists in practice to identify and better define LS. The identification of the special variants suggests a role of the stromal lymphocytes in the process of carcinogenesis. Confirmation of the observations with more studies is necessary to determine the significance of these findings.

Abstract
BACKGROUND To investigate the surgical methods and clinical results of robot-assisted laparoscopic antegrade inguinal lymphadenectomy. METHODS A retrospective study was performed on clinical data from 19 patients with penile cancer admitted from March 2013 to October 2017. Among them, nine patients underwent robot-assisted laparoscopic antegrade inguinal lymphadenectomy (robot-assisted group) and 10 patients underwent open inguinal lymphadenectomy (open group). In the robot-assisted group, preoperative preparation, patient position, robot placement, design of operating channel and establishment of operating space are described. Key surgical procedures and techniques are also summarized. In addition, the number of lymph nodes removed, postoperative complications and follow-up in both groups were statistically analyzed. RESULTS For the 9 patients in the robot-assisted group, surgery was successfully accomplished at 17 sides without intraoperative conversion to open surgery. The surgery time for each side was 45~90 min using laparoscope with an average of 68.5 ± 13.69 min/side. The intraoperative blood loss was estimated to be < 10 ml/side, and the number of removed lymph nodes was not significantly different from that of the open group (12 ± 4.2/side vs.11 ± 5.8/side, P = 0.84). There were no postoperative complications such as skin necrosis, delayed wound healing and cellulitis in the robot-assisted group. Skin-related complications occurred in 9 (45%) of the 20 sides in the open group. During a median follow-up of 25 months in robot-assisted group and 52.5 mouths in open group, was not significantly different there were no statistical differences in recurrence-free survival between the groups (75% vs 60%, p = 0.536). CONCLUSION Robot-assisted laparoscopic antegrade inguinal lymphadenectomy achieved the desired surgical outcomes with fewer intraoperative and postoperative complications. The robotic arms of the surgical system were placed between the lower limbs of each patient. There was no need to re-position the robotic arms during bilateral inguinal lymphadenectomy. This simplified the procedure and reduced the use of trocars. If necessary, pelvic lymphadenectomy could be performed simultaneously using the original trocar position.

Abstract
Penile intraepithelial neoplasia (PeIN) is currently classified in human papillomavirus (HPV)- and non-HPV-related subtypes with variable HPV genotypes. PeINs are frequently associated with other intraepithelial lesions in the same specimen. The aim of this study was to detect and compare HPV genotypes in PeINs and associated lesions using high-precision laser capture microdissection-polymerase chain reaction and p16INK4a immunostaining. We evaluated resected penile specimens from 8 patients and identified 33 PeINs and 54 associated lesions. The most common subtype was warty PeIN, followed by warty-basaloid and basaloid PeIN. Associated lesions were classical condylomas (17 cases), atypical classical condylomas (2 cases), flat condylomas (9 cases), atypical flat condylomas (6 cases), flat lesions with mild atypia (12 cases), and squamous hyperplasia (8 cases). After a comparison, identical HPV genotypes were found in PeIN and associated lesions in the majority of the patients (7 of 8 patients). HPV16 was the most common genotype present in both PeIN and corresponding associated lesion (50% of the patients). Nonspecific flat lesions with mild atypia, classical condylomas, and atypical condylomas were the type of associated lesions most commonly related to HPV16. Other high-risk HPV genotypes present in PeIN and associated nonspecific flat lesion with mild atypia were HPV35 and HPV39. In this study of HPV in the microenvironment of penile precancerous lesions, we identified identical high-risk HPV genotypes in PeIN and classical, flat, or atypical condylomas and, specially, in nonspecific flat lesions with mild atypia. It is possible that some of these lesions represent hitherto unrecognized precancerous lesions.

Abstract
INTRODUCTION Penile cancer (PC) occurs less frequently in Europe and in the United States than in South America and parts of Africa. Lymph node (LN) involvement is the most important prognostic factor, and inguinal LN (ILN) dissection can be curative; however, ILN dissection has high morbidity. A nomogram was previously developed based on clinicopathological features of PC to predict ILN metastases. Our objective was to conduct an external validation of the previously developed nomogram based on our population. MATERIALS AND METHODS We included men with cN0 ILNs who underwent ILN dissection for penile carcinoma between 2000 and 2014. We performed external validation of the nomogram considering three different external validation methods: k-fold, leave-oneout, and bootstrap. We also analyzed prognostic variables. Performance was quantified in terms of calibration and discrimination (receiver operator characteristic curve). A logistic regression model for positive ILNs was developed based on clinicopathological features of PC. RESULTS We analyzed 65 men who underwent ILN dissection (cN0). The mean age was 56.8 years. Of 65 men, 24 (36.9%) presented with positive LNs. A median 21 ILNs were removed. Considering the three different methods used, we concluded that the previously developed nomogram was not suitable for our sample. CONCLUSIONS In our study, the previously developed nomogram that was applied to our population had low accuracy and low precision for correctly identifying patients with PC who have positive ILNs.

Glans Resurfacing with Skin Graft for Penile Cancer: A Step-by-Step Video Presentation of the Technique and Review of the Literature. BIOMED RESEARCH INTERNATIONAL 2019; 2019:5219048. [PMID: 31312658 PMCID: PMC6595175 DOI: 10.1155/2019/5219048] [Citation(s) in RCA: 3] [Impact Index Per Article: 0.6] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Subscribe] [Scholar Register] [Received: 02/13/2019] [Accepted: 04/14/2019] [Indexed: 11/17/2022]
Abstract
Introduction Glans resurfacing has been suggested as a treatment option for the surgical management of superficial penile cancer (Tis, Ta, T1aG1, T1aG2). In this article we describe in detail the glans resurfacing technique with skin graft for penile cancer in a video presentation and we review the current knowledge of the literature. Material and Methods The procedure is described in a stepwise fashion. Initially the patient is circumcised. The glans is marked in quadrants and completely stripped by dissecting and removing the epithelium and subepithelium layer of the glans. Deep spongiosal biopsies are taken to exclude invasion. Each quadrant is sent separately for biopsy. The surface of the graft size needed is estimated. A partial thickness skin graft is harvested from the thigh with a dermatome. The skin graft is then fenestrated. The graft is rolled over the glans and quilted with multiple sutures. A silicone 16F Foley catheter and a suprapubic catheter are placed. The penis is dressed with multiple gauzes and compressed with an elastic band. Results The patient is discharged the next day. The dressing and Foley catheter are removed in 7 days. The patient continues to use the suprapubic catheter for 7 more days. The patient refrains from any sexual activity for 6 weeks and is closely followed. Conclusions Glans resurfacing is an emerging new appealing surgical technique that is already a recommendation in the EAU guidelines for the treatment of premalignant and superficial penile lesions. The overall satisfaction rate and recovery of the sexual function are acceptable, and it can be considered an ideal procedure to treat superficial penile cancer.

Abstract
Purpose: We aimed to reveal the effects of marital status on survival outcomes in patients with penile cancer. Methods: Patients with penile cancer who were diagnosed between 2004 and 2015 were identified by using the Surveillance, Epidemiology and End Results (SEER) database. Kaplan-Meier and Cox regressions were used to analyse the effects of marital status on overall survival (OS) and cancer-specific survival (CSS). Results: Among 3,195 eligible patients with penile cancer, 1,951 (61.1%) patients were married, 365 (11.4%) were divorced or separated, 327 (10.2%) were widowed and 552 (17.3%) were single. The widowed patients had the worst OS median survival time (22 months) and CSS median survival time (23.5 months). Marital status was an independent prognostic factor for OS and CSS of penile cancer patients. The multivariate Cox regression showed that widowed patients exhibited the poorest OS (hazard ratio [HR]: 1.73; 95% confidence interval [CI]: 1.48-2.03, p < 0.001) and the poorest CSS (HR: 1.64; 95% CI: 1.144-1.279, p < 0.001) compared with married patients. Similar results were observed in our centre database and the subgroup analyses based on the SEER stage and grade. Conclusions: In our study, we found that marital status was an independent prognostic factor for survival in patients with penile cancer. Additionally, widowed patients had the lowest OS and CSS compared with married patients.

Abstract
Purpose This study aimed to evaluate the statuses of P16INK4A expression and human papillomavirus (HPV) infection among patients with penile cancer at a single Korean institution. Patients and Methods Fourteen patients with penile cancer at our center were retrospectively identified and their clinicopathological data were analyzed. The patients' HPV and P16INK4A expression status (a known tumor suppressor protein) were tested using genotyping with a DNA chip assay and immunohistochemical staining, respectively. The results regarding HPV status were compared to those from another Asian study. Results The mean age at diagnosis was 60 years (range: 34–86 years). The median tumor size was 3.0 cm (range: 0.6–4.7 cm). Ten tumors were located on the penile glans. Five patients tested positive for HPV DNA (5/14, 36%) and all cases involved HPV type 16 (5/5, 100%). Positive expression of P16INK4A was observed in 6 cases (6/14, 43%). Among the HPV positive cases, 80% of cases (4/5) were also positive for P16INK4A. The prevalence of HPV infection in our study (36%) was higher than in a previous Asian study (23%). Conclusions This is the first study to evaluate the prevalence of HPV infection and P16INK4A expression among patients with penile cancer at a single Korean institution. The prevalence of HPV (36%) was slightly higher than the results from a previous Asian study. Additional multi-center studies are needed to better understand penile cancer in Korea and to identify biomarkers that can determine high-risk cases and predict their prognosis.

Abstract
BACKGROUND Early diagnosis is fundamental for the investigation and treatment of penile lesions. There is an unfortunate documented delayed in presentation and diagnosis of penile lesions. Literature is scant regarding the risk factors contributing to this delay in a Mediterranean population. Few previous reports are published in entirely different homogeneous populations. The objective of this study was to provide an analysis of the causes and risk factors related to the delay of the first medical visit in a North Italian population subgroup. METHODS From September 2004 to September 2017, 184 consecutive patients were treated at our institute with a surgical approach for a penile lesion. The epidemiological factors and reasons for the delay to diagnosis were recorded during personal or telephonic interviews. Univariate logistic regression models were performed to screen for an effect of the clinical and demographic variables on the delay in diagnosis. Variables with a P value <0.05 were entered into multivariate analysis, where the delay in diagnosis was the dependent variable. RESULTS One hundred and thirteen patients were enrolled. The average patient age was fifty-eight. The average delay between the appearance of the lesion and the first medical consultation was fifty-three days. The principal cause of delay was the lack of knowledge of penile lesions and secondly, the feeling of embarrassment of having to visit a doctor. The multivariate analysis reported a significant correlation between the level of education, sexual activity and extramarital affairs on the delay in presentation (P values respectively: 0.01, 0.009 and 0.04). CONCLUSIONS Patients education regarding this pathology and its potential danger is inadequate and thus it is necessary to implement a campaign of information and prevention in order to reduce delayed diagnosis.

Abstract
BACKGROUND The objectives of this study were to determine the minimum incidence of penile cancer in the poorest Brazilian state, and to describe the epidemiologic and clinical characteristics of patients diagnosed with the disease. METHODS A retrospective study of 392 patients diagnosed with penile cancer in the three most important referral center in the state was conducted during 2004-2014. RESULTS The age-standardized incidence was 6.15 per 100,000 and the crude annual incidence was 1.18 per 100,000. More than half (61.1%) of the tumors were histological grades 2 and 3, and 66.4% of tumors were classified as at least stage T2. The average age of patients was 58.6 ± 15.7 years (range, 18 to 103 years), with 20.8% of patients ≤40 years of age at diagnosis. The vast majority underwent penectomy (93%). Only 41.8% underwent lymphadenectomy, 58 patients (14.8%) received chemotherapy, and 54 patients (13.8%) received radiotherapy. Stage 3/4 and vascular invasion were statically significant at disease-free survival analysis. CONCLUSION The state of Maranhão has the highest incidence of penile cancer in Brazil and globally. Tumors are locally advanced and at the time of diagnosis, and there is a high frequency among young individuals. Patients have a low socioeconomic status, making it difficult to complete treatment and receive appropriate follow-up.

Abstract
PURPOSE OF REVIEW We review recent advancements in staging and imaging of penile cancer, including surveillance after therapy. RECENT FINDINGS For cN0 patients, the sentinel lymph node biopsy is currently considered the preferred way for invasive staging. It has largely replaced other modalities such as staging inguinal lymphadenectomy. Its diagnostic value increases when combined with other staging modalities such as ultrasound with fine-needle aspiration cytology (US-FNAC) or fluorodeoxyglucose-PET with computed tomography (PET/CT). In patients with palpably suspicious nodes (cN+), imaging is more useful. PET/CT has shown good accuracy in a limited number of small studies. US-FNAC can confirm nodal metastatic disease. A staging inguinal lymphadenectomy is of therapeutic value but is associated with significant morbidity. Omitting staging inguinal lymphadenectomy was recently described; one study showed well tolerated use of sentinel lymph node biopsy combined with intraoperative ultrasound-guided resection of suspicious nodes in cN+ patients. Therapeutic inguinal lymphadenectomy was only performed in the 42% of groins with metastases confirmed by disorder. For M-staging, PET/CT has shown good sensitivity, and its role should be further evaluated. Follow-up and surveillance rely on physical examination and US-FNAC. SUMMARY Over the past decade, staging and treatment of penile cancer have become less invasive, while survival tends to improve.

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.

Abstract
OBJECTIVE To determine the global incidence of penile cancer. METHODS A systematic review and meta-analysis of observational studies was performed, with no limits on their language of publication. Analyses were performed using Stata 13 statistical software. A random-effects model was used, according to the heterogeneity found in the studies. The main outcome was expressed in terms of age-standardized incidence. RESULTS A total of 23 studies were eligible, with 71 156 penile cancer patients in 86 countries. According to the review conducted, the estimated age-standardized incidence of penile cancer worldwide is 0.84 cases per 100 000 person-years (95% confidence interval: 0.79-0.89). Romania reported the highest incidence, 7.26 per 100 000 person-years, between 1983 and 1987; however, some countries in Latin America and Africa reported an incidence of between 2.0 and 5.7 per 100 000. CONCLUSIONS Penile cancer is considered a rare malignancy due to its already-known, particularly low incidence rate. The estimated age-standardized incidence rate by the world standard population today is 0.84 cases per 100 000 person-years. There were no significant differences in the incidence rate of penile cancer with respect to the distribution by continent or the trend over time.

Long-term evaluation of urinary, sexual, and quality of life outcomes after brachytherapy for penile carcinoma. Brachytherapy 2017; 17:221-226. [PMID: 29089276 DOI: 10.1016/j.brachy.2017.09.006] [Citation(s) in RCA: 10] [Impact Index Per Article: 1.4] [Reference Citation Analysis] [Abstract] [Key Words] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/24/2017] [Revised: 09/20/2017] [Accepted: 09/21/2017] [Indexed: 11/20/2022]
Abstract
PURPOSE Brachytherapy (BT) is an effective organ-preserving treatment for selected localized penile carcinoma, providing high local control rates. Long-term functional results however, are still insufficiently evaluated. METHODS AND MATERIALS All consecutive patients treated with low-dose-rate or pulse-dose-rate BT in our institute for a localized penile cancer and who were in first complete remission and followed for at least 3 years were included. A self-reporting questionnaire was sent, to assess: 1/urinary function, 2/sexual function, 3/cosmetic aspect of the penis, and 4/quality of life. RESULTS Thirty-nine patients fulfilled inclusion criteria and were sent the questionnaire. Twenty-three patients (59%) answered. Median age was 63.4 years, (interquartile range [IR]: 49.7-67.0). Median followup was 5.9 years (IR: 5.2-6.7). The urinary scores showed moderate lower urinary tract symptoms. During the followup, a urethral dilation or self-catheterization had been necessary in 30% and 13%, respectively. Sixteen (70%) patients continued to maintain a sexual activity and the erectile dysfunction was mild. Finally, quality of life was good with a median score of 80/100 (IR = 65-90) and was only impacted by pain (p = 0.02). Overall, 57% and 39% declared having none or moderate pain/discomfort, respectively. CONCLUSIONS Although this questionnaire needs to be validated in an independent cohort, our results show the moderate impact of BT on functional outcomes, confirming that it is an adequate first-intent organ-sparing strategy in patients with localized penile carcinoma.

Human Papillomavirus (HPV) Genotypes in Condylomas, Intraepithelial Neoplasia, and Invasive Carcinoma of the Penis Using Laser Capture Microdissection (LCM)-PCR: A Study of 191 Lesions in 43 Patients. Am J Surg Pathol 2017; 41:820-832.

Abstract
Laser capture microdissection-polymerase chain reaction (LCM-PCR) supported by p16 was used for the first time to demonstrate human papillomavirus (HPV) DNA in histologically specific penile lesions, which were as follows: squamous hyperplasia (12 lesions, 10 patients), flat lesions (12 lesions, 5 patients), condylomas (26 lesions, 7 patients), penile intraepithelial neoplasia (PeIN) (115 lesions, 43 patients), and invasive squamous cell carcinomas (26 lesions, 26 patients). HPV was detected by whole-tissue section and LCM-PCR. LCM proved to be more precise than whole-tissue section in assigning individual genotypes to specific lesions. HPV was negative or very infrequent in squamous hyperplasia, differentiated PeIN, and low-grade keratinizing variants of carcinomas. HPV was strongly associated with condylomas, warty/basaloid PeIN, adjacent flat lesions, and warty/basaloid carcinomas. A single HPV genotype was found in each lesion. Some condylomas and flat lesions, especially those with atypia, were preferentially associated with high-risk HPV. Unlike invasive carcinoma, in which few genotypes of HPV were involved, there were 18 HPV genotypes in PeIN, usually HPV 16 in basaloid PeIN but marked HPV heterogeneity in warty PeIN (11 different genotypes). Variable and multiple HPV genotypes were found in multicentric PeIN, whereas unicentric PeIN was usually related to a single genotype. There was a correspondence among HPV genotypes in invasive and associated PeIN. p16 was positive in the majority of HPV-positive lesions except condylomas containing LR-HPV. p16 was usually negative in squamous hyperplasia, differentiated PeIN, and low-grade keratinizing variants of squamous cell carcinomas. In summary, we demonstrated that LCM-PCR was a superior research technique for investigating HPV genotypes in intraepithelial lesions. A significant finding was the heterogeneity of HPV genotypes in PeIN and the differential association of HPV genotypes with subtypes of PeIN. The presence of atypia and high-risk HPV in condylomas and adjacent flat lesions suggests a precursor role, and the correspondence of HPV genotypes in invasive carcinomas and associated PeIN indicates a causal relation. Data presented support the bimodal hypothesis of penile cancer carcinogenesis in HPV-driven and non-HPV-driven carcinomas and justify the current WHO pathologic classification of PeIN in special subtypes.

Abstract
Purpose The aim of this study was to assess the clinicopathologic characteristics of penile cancer, including patterns of therapy, oncologic results, and survival. Materials and Methods Between January 2005 and July 2015, 71 patients at 6 institutions who had undergone penectomy or penile biopsy were enrolled. Their medical records were reviewed to identify the mode of therapy, pathology reports, and cancer-specific survival (CSS) rate. Results Clinicopathologic and outcome information was available for 52 male patients (mean age, 64.3 years; mean follow-up, 61.4 months). At presentation, 17 patients were node-positive, and 4 had metastatic disease. Management was partial penectomy in 34 patients, total penectomy in 12 patients, and chemotherapy or radiotherapy in 6 patients. The pathology reports were squamous cell carcinoma in 50 patients and other types of carcinoma in the remaining 2 patients. Kaplan-Meier survival analysis showed a 5-year CSS rate of 84.0%. In univariate and multivariate analyses, the American Joint Committee on Cancer (AJCC) stage and pathologic grade were associated with survival. Conclusions Partial penectomy was the most common treatment of penile lesions. The oncologic outcomes were good, with a 5-year CSS of 84.0%. The AJCC stage and pathologic grade were independent prognostic factors for survival.
