Abstract
Neoplasm of the penis is relatively rare in most regions representing 0-2% of cancers worldwide. While the penis can be affected by sarcomas, basal cell carcinomas or even melanoma, Penile Squamous Cell Carcinoma (PSCC) represents approximately 95% of all penile neoplasms. Despite its rarity and most common presentation at later decades of life most individuals diagnosed with PSCC are faced with significant decrease in quality of life. The prevalence and incidence vary among different regions and populations, but a common trend is for diagnosis to occur late (stage 4). Underdeveloped countries are traditionally reported to have higher incidence rates; however, rates may vary significantly between urban and rural areas even in developed countries. Age adjusted rates are on the rise in some countries that used to have incidence rates of 1:100 000 or less. The list of associated risk factors is long and includes among others, lack of neonatal circumcision, poor genital hygiene, socioeconomic status, history of human papillomavirus (HPV) infection and penile intraepithelial neoplasia (PeIN). Many risk factors are widely debated among experts however HPV and PeIN are indisputable risk factors, and both also form part of the classification system for PSCC. Both conditions may have occurred in the past or be present at the time of diagnosis and identifying them plays a major role in management strategies. For such a rare condition PSCC can present in many different forms clinically making diagnosis no easy feat. Diagnosis of PSCC is done through clinical examination, including lymph node palpation, followed by a biopsy, which is essential for the classification. Lymph node involvement is a common finding at first presentation and investigation of spread to deep nodes is important and can be done with the aid of PET-CT. Treatment options for PSCC include surgery, chemotherapy, and radiation therapy. Surgical removal of the tumor is considered the most effective however can lead to severe decrease of quality of life. Chemotherapy is used in the case of fixed or bulky lymph nodes, where surgery is not indicated, and for distant metastasis. Radiation therapy is particularly effective in the case of HPV-positive PSCC.

Abstract
Penile malignancy is the third most common male-specific genitourinary malignancy, with squamous cell carcinoma representing the most common histologic type. Squamous cell carcinoma is an epithelial malignancy, frequently developing from the mucosal surfaces of the foreskin, glans, and coronal sulcus and manifesting as a distal infiltrative or ulcerated mass. This typically occurs in men from the 6th to 8th decades of life, and risk factors include human papillomavirus, phimosis, presence of foreskin and poor hygiene, chronic inflammatory conditions such as lichen sclerosus, trauma, and smoking. Primary urethral malignancies including urothelial carcinoma and adenocarcinoma can occur but may lack this distal predilection. Sarcoma, melanoma, leukemia or lymphoma, and metastatic disease are less common sources of penile malignancy. Because of the sensitive nature of penile malignancies, there may be delays in seeking care and in subsequent diagnosis. Recently, the staging guidelines for penile cancer have been updated concurrently with a shift toward more penile-preserving therapies, which have led to a larger role of imaging in diagnosis, staging, and treatment planning for penile malignancies. A variety of imaging modalities may play a role in the identification and staging of penile malignancy, including an increased use of MRI for local staging of tumors, CT and PET/CT for identification of nodal and distant disease, and US for image-guided biopsy. The authors discuss an imaging approach to a spectrum of penile malignancies, with an emphasis on radiologic and pathologic correlation and how knowledge of normal tissue types and anatomic structures can aid in the diagnosis and staging of these tumors. ©RSNA, 2023 Quiz questions for this article are available in the supplemental material.

Multi-parametric MRI without artificial erection for preoperative assessment of primary penile carcinoma: A pilot study on the correlation between imaging and histopathological findings. Eur J Radiol Open 2023; 10:100478. [PMID: 36793771 PMCID: PMC9922909 DOI: 10.1016/j.ejro.2023.100478] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/06/2022] [Revised: 01/23/2023] [Accepted: 01/24/2023] [Indexed: 01/29/2023] Open
Abstract
Purpose We aimed to evaluate the diagnostic potential of non-erectile multi-parametric magnetic resonance imaging (mpMRI) for preoperative assessment of primary penile squamous cell carcinoma (SCC). Method Twenty-five patients who underwent surgery for penile SCC were included. Preoperative mpMRI without artificial erection was performed in all patients. The preoperative MRI protocol consisted of high-resolution morphological and functional sequences (diffusion-weighted imaging and dynamic contrast-enhanced MRI perfusion) covering the penis and lower pelvis. T and N staging, according to the 8th edition of the Union for International Cancer Control TNM classification, as well as the largest diameter and thickness/infiltration depth of the primary lesions were determined in all patients. Imaging data were retrospectively collected and compared with the final histopathology reports. Results Very good agreement was observed between MRI and histopathology for the involvement of corpus spongiosum (p = 0.002) and good agreement was observed for the involvement of penile urethra and tunica albuginea/corpus cavernosum (p < 0.001 and p = 0.007, respectively). Good agreement was observed between MRI and histopathology for overall T staging and weaker, but still good agreement was observed for N staging (p < 0.001 and p = 0.002, respectively). A strong and significant correlation was observed between MRI and histopathology for the largest diameter and thickness/infiltration depth of the primary lesions (p < 0.001). Conclusions Good concordance was observed between MRI and histopathological findings. Our initial findings indicate that non-erectile mpMRI is useful in preoperative assessment of primary penile SCC.

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.

Abstract
OBJECTIVE To update French oncology guidelines concerning penile cancer. METHODS Comprehensive Medline search between 2020 and 2022 upon diagnosis, treatment and follow-up of testicular germ cell cancer to update previous guidelines. Level of evidence was evaluated according to AGREE-II. RESULTS Epidermoid carcinoma is the most common penile cancer histology. Physical examination is mandatory to define local and inguinal nodal cancer stage. MRI with artificial erection can help to assess deep infiltration in cases of organsparing intention. Node negative patients (defined by palpation and imaging) will present micro nodal metastases in up to 25% of cases. Invasive lymph node assessment is thus advocated except for low risk patients. Sentinel node dynamic biopsy is the first line technique. Modified bilateral inguinal lymphadenectomy is an option with higher morbidity. 18-FDG-PET is recommended in patients with palpable nodes. Chest, abdominal and pelvis computerized tomography is an option. Fine needle aspiration (when positive) is an easy way to assess inguinal palpable node pathological involvement. Its results determine the type of lymphadenectomy to be performed (for diagnostic or curative purposes). Treatment is mostly surgical. Free margins status is essential, but it also has to be organ-sparing when possible. Brachytherapy and topic agents can cure in selected cases. Lymph node assessment should be synchronous to the removal of the tumour when possible. Limited inguinal lymph node involvement (pN1 stage) can be cured with the only lymphadenectomy. In case of larger lymph node stage, one should consider multidisciplinary treatment including chemotherapy and inclusion in a trial. CONCLUSIONS Penile cancer needs demanding surgery to be cured, surrounded by chemotherapy in node positive patients. Lymph nodes involvement is a major prognostic factor. Thus, inguinal node assessment cannot be neglected.

Abstract
piRNAs (PIWI-interacting RNAs) are small non-coding RNAs capable of regulation of transposon and gene expression. piRNAs utilise multiple mechanisms to affect gene expression, which makes them potentially more powerful regulators than microRNAs. The mechanisms by which piRNAs regulate transposon and gene expression include DNA methylation, histone modifications, and mRNA degradation. Genitourinary cancers (GC) are a large group of neoplasms that differ by their incidence, clinical course, biology, and prognosis for patients. Regardless of the GC type, metastatic disease remains a key therapeutic challenge, largely affecting patients’ survival rates. Recent studies indicate that piRNAs could serve as potentially useful biomarkers allowing for early cancer detection and therapeutic interventions at the stage of non-advanced tumour, improving patient’s outcomes. Furthermore, studies in prostate cancer show that piRNAs contribute to cancer progression by affecting key oncogenic pathways such as PI3K/AKT. Here, we discuss recent findings on biogenesis, mechanisms of action and the role of piRNAs and the associated PIWI proteins in GC. We also present tools that may be useful for studies on the functioning of piRNAs in cancers.

Abstract
The majority of penile malignant tumors are squamous cell carcinomas. They are pathologically defined as epithelial neoplasms originating in the squamous cells of the inner mucosal lining of the glans, coronal sulcus or foreskin. Tumor location and site of origin is preferentially in glans (70%) followed by foreskin (25%) and coronal sulcus (5%). Despite the variable geographic distribution, pathological features of penile carcinomas in areas of high- and low-risk are similar. Penile tumors are morphologically heterogeneous. A major advance, based on biological, etiological and prognostic factors, is the 2016 WHO classification separating epithelial penile neoplasia, precancerous and invasive, in non-HPV and HPV-related.

Abstract
Penile cancer is one of the male-specific cancers. Accurate pretreatment staging is crucial due to a plethora of treatment options currently available. The 8th edition American Joint Committee on Cancer-Tumor Node and Metastasis (AJCC-TNM) revised the staging for penile cancers, with invasion of corpora cavernosa upstaged from T2 to T3 and invasion of urethra downstaged from T3 to being not separately relevant. With this revision, MRI is more relevant in local staging because MRI is accurate in identifying invasion of corpora cavernosa, while the accuracy is lower for detection of urethral involvement. The recent European Urology Association (EAU) guidelines recommend MRI to exclude invasion of the corpora cavernosa, especially if penis preservation is planned. Identification of satellite lesions and measurement of residual-penile-length help in surgical planning. When nonsurgical treatment modalities of the primary tumor are being considered, accurate local staging helps in decision-making regarding upfront inguinal lymph node dissection as against surveillance. MRI helps in detection and extent of inguinal and pelvic lymphadenopathy and is superior to clinical palpation, which continues to be the current approach recommended by National Comprehensive Cancer Network (NCCN) treatment guidelines. MRI helps the detection of "bulky" lymph nodes that warrant neoadjuvant chemotherapy and potentially identify extranodal extension. However, tumor involvement in small lymph nodes and differentiation of reactive vs. malignant lymphadenopathy in large lymph nodes continue to be challenging and the utilization of alternative contrast agents (superparamagnetic iron oxide), positron emission tomography (PET)-MRI along with texture analysis is promising. In locally recurrent tumors, MRI is invaluable in identification of deep invasion, which forms the basis of treatment. Multiparametric MRI, especially diffusion-weighted-imaging, may allow for quantitative noninvasive assessment of tumor grade and histologic subtyping to avoid biopsy undersampling. Further research is required for incorporation of MRI with deep learning and artificial intelligence algorithms for effective staging in penile cancer. Level of Evidence: 5 Technical Efficacy: Stage 3 J. Magn. Reson. Imaging 2020;51:1612-1629.

Abstract
PURPOSE To describe the survival outcomes of organ sparing surgery (OSS), partial penectomy (PP), and total penectomy (TP) in pathological stage pT1/pT2 penile cancer (PC) as reported in the United States National Cancer Data Base. METHODS Patients with pT1/pT2 PC, treated with surgery as their primary treatment modality were classified into 3 groups according to the type of surgery into OSS, PP, and TP. Patient and tumor characteristics of the groups were compared using bivariate analysis, and Cox- proportional hazard model was used for survival analysis. RESULTS A total of 4,238 patients were examined. There were 1,211, 2,360, and 584 patients in the OSS, PP, and TP groups, respectively. In 83 patients, the type of surgery was missing. The 5- and 10-year overall survival rates for OSS, PP, and TP were 88% and 74% vs. 85% and 72% vs. 79% and 63%, respectively (P ≤ 0.001). In addition, in a multivariable model for predictors of patient survival, OSS did not predict poor patient survival (hazard ratio = 0.88, CI: 0.64-1.21). CONCLUSIONS Our results demonstrate, at national level, OSS in early stage PC provided comparable outcomes in selected patients compared to PP and TP. Also, organ preservation was not associated with any significant reduction in patient survival in early stage PC. Our results help with early stage PC patient informed treatment decisions and anticipated outcomes.

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
Penile carcinoma (PeCa) represents an important public health problem in poor and developing countries. Despite its unpredictable behavior and aggressive treatment, there have only been a few reports regarding its molecular data, especially epigenetic mechanisms. The functional diversity in different cell types is acquired by chromatin modifications, which are established by epigenetic regulatory mechanisms involving DNA methylation, histone acetylation, and miRNAs. Recent evidence indicates that the dysregulation in these processes can result in the development of several diseases, including cancer. Epigenetic alterations, such as the methylation of CpGs islands, may reveal candidates for the development of specific markers for cancer detection, diagnosis and prognosis. There are a few reports on the epigenetic alterations in PeCa, and most of these studies have only focused on alterations in specific genes in a limited number of cases. This review aims to provide an overview of the current knowledge of the epigenetic alterations in PeCa and the promising results in this field. The identification of epigenetically altered genes in PeCa is an important step in understanding the mechanisms involved in this unexplored disease.

C-MET is expressed in the majority of penile squamous cell carcinomas and correlates with polysomy-7 but is not associated with MET oncogene amplification, pertinent histopathologic parameters, or with cancer-specific survival. Pathol Res Pract 2013; 209:215-20. [PMID: 23490239 DOI: 10.1016/j.prp.2013.02.002] [Citation(s) in RCA: 11] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 05/25/2012] [Revised: 11/29/2012] [Accepted: 02/05/2013] [Indexed: 01/02/2023]
Abstract
We assessed c-MET expression and oncogene amplification in a cohort enrolling 92 surgically treated penile squamous cell carcinomas (PSCCs). A tissue microarray was constructed for c-MET immunohistochemistry (IHC) and chromogenic silver in situ hybridization (SISH). Two independent pathologists evaluated IHC by employing the breast cancer scoring rules, and scored the presence of MET oncogene amplification and/or polysomy-7. Eighty study cases (87%) showed c-MET expression. No study case had MET oncogene amplification, but 42 patients (45.7%) had polysomy-7. Polysomy-7 showed a significant positive correlation with c-MET expression (ρ=0.323, p=0.002). Neither c-MET expression nor polysomy-7 was associated with histopathologic parameters or with cancer-specific survival (median post-surgical follow-up 32 months). Our data suggest that the majority of PSCCs exhibit c-MET expression which is not associated with oncogene amplification, but might be attributable to polysomy-7. Further studies should investigate the expression and activation of downstream molecules functionally involved in c-MET pathway signaling, and clarify the so far unresolved role of c-MET inhibitors as potential targeted therapies in PSCCs with metastatic dissemination.

Abstract
Penile squamous cell carcinoma (SCC) is considered a loco-regional disease with a fairly predictable pattern of progression. Widespread dissemination occurs in at least one-third of the patients. Local recurrence (defined as the presence of tumor after a primary treatment affecting any remainder tissue, including skin, erectile corpora, or urethra) present in up to 30% of the patients increases the risk of regional inguinal and pelvic lymph nodes metastases. The aim of this study was to identify adverse pathologic prognostic factors in patients with recurrent tumors. Clinicopathologic features of 81 surgically treated patients (25 with recurrent and 56 with nonrecurrent SCC) were evaluated; 56 patients (19 with recurrent and 37 with nonrecurrent tumors) additionally received groin dissections. Follow-up (2 to 372 mo, mean of 71 mo) was obtained in all patients. Comparison of recurrent tumors at the time of the primary diagnosis and of recurrence showed that histologic subtype and grade were identical in 76% of the cases and converted to a higher grade tumor in 24% of the cases, especially, in patients treated with local excisions and circumcisions. Most of the recurrences (67%) seemed at or before 12 months. Comparison of recurrent and nonrecurrent tumors showed that high grade tumors (basaloid and sarcomatoid) tended to be significantly associated with recurrent tumors, whereas low grade variants (papillary, warty and verrucous) were more frequent in the nonrecurrent group; recurrent tumors invaded into deeper anatomic levels than nonrecurrent tumors. The incidence of inguinal lymph node metastasis was higher in recurrent tumors (79% vs. 49%, P=0.0272). Cancer-specific survival was of 46% versus 76% at 3 years of follow-up in recurrent and nonrecurrent tumors, respectively. Patients with recurrent tumors had a median survival of 2.9 years; no major changes in survival were noted after 3 years of follow-up. Mortality was higher in the recurrent group (56% vs. 29%, P=0.0188); 80% of patients with high-grade tumors (basaloid, sarcomatoid, and high grade usual or hybrid verrucous SCCs) died from penile cancer. Mortality in patients with usual SCC was higher in the recurrent group, but similar in basaloid and sarcomatoid SCCs. After 3 years there was no survival difference in patients with low-grade recurrent tumors; however, in the high grade recurrent group there was a progressive and gradual decrease in survival from 2 to 10 years (median survival of 2.5 y). In summary, histologic subtypes and grades of SCCs were similar in the majority of original and recurrent carcinomas. Inguinal metastasis and mortality were higher in recurrent than in nonrecurrent carcinomas. Basaloid, sarcomatoid, and mixed usual-verrucous variants and invasion of corpora cavernosa or preputial skin were significant adverse prognostic factors of recurrent carcinomas. Local excision and partial penectomy were not adequate procedures for sarcomatoid and basaloid penile carcinomas. Carcinomas of foreskin had a better prognosis. Conversion from low to high-grade carcinoma was related to significant mortality. The identification of the adverse prognostic factors found in this study should be the base for an aggressive initial therapy to prevent recurrence in a subset of penile cancers. Re-excision of the recurrent tumor permitted the control of the disease only in one-third of the patients.

Abstract
The aim of this study was to describe pathologic features found at autopsy of 14 patients with penile cancer. Nine patients died from disseminated disease; 5 of them presented local/regional recurrences. Five patients died from other causes, 2 of them postoperatively. Local recurrence sites were corpus cavernosum, Buck’s fascia and urethra, regional skin, and prostate. Metastatic sites were lymph nodes (9 cases), liver (7 cases), lungs (6 cases), heart (5 cases), adrenals, bone and skin (3 cases each), thyroid and brain (2 cases each), and pancreas, spleen, and pleura (1 case each). Patients with heart metastasis had arrhythmias. Patients who died and who did not die from penile cancer had different profiles: low-grade superficial tumors with usual and warty subtypes versus high-grade deeply invasive basaloid or hybrid verrucous/sarcomatoid carcinomas. A natural history model for penile cancer routes of spread is proposed: local intrapeneal, regional and systemic nodes, regional skin, liver, lungs, heart, and other multiple sites.

Abstract
Penile squamous cell carcinomas (SCCs) invading to a depth inferior to 5 mm usually have very low risk for regional metastasis, whereas tumors thicker than 10 mm have a high metastatic potential. A significant number of squamous cell carcinomas, however, belong to an intermediate category (5 to 10 mm in thickness) in which the incidence of regional lymph node metastasis is very difficult to predict. Consequently, a frequent clinical dilemma is whether to perform or not inguinal dissection in this group of lesions. The objective of this study was to evaluate multiple risk factors for regional metastasis in tumors 5 to 10-mm thick. One hundred thirty-four partial penectomies with invasive carcinomas 5 to 10-mm thick, all of which with corresponding inguinal lymph node dissection, were evaluated. Factors evaluated were--patient's age, anatomic site, histologic grade, tumor thickness, anatomic levels of invasion, and vascular and perineural invasion. Grades were classified as 1, well; 2, moderately; and 3, poorly differentiated. To evaluate independent significance of various prognostic factors, a logistic regression analysis was performed, and a nomogram was prepared to evaluate metastatic risk according to histologic grade and perineural invasion. Groin metastasis was found in 66 of 134 patients (49%). High histologic grade and perineural invasion were statistically significant pathologic factors associated with groin metastasis. Nodal metastases were found in 2 of 25 grade 1 (8%), 24 of 46 grade 2 (52%), and 40 of 63 grade 3 carcinomas (63%) (P value 0.0001). Of 48 patients with perineural invasion, metastasis was found in 33 cases (69%) (P value 0.001). The average tumor thickness, anatomic level of invasion, and presence of vascular invasion were not statistically significantly different in metastasizing and nonmetastasizing neoplasms. Fifty percent of tumors invading 5 to 10 mm were not associated with metastasis and may be spared a nodal dissection. In this subset of patients, high histologic grade and perineural invasion were significant and useful risk factors associated with regional metastasis. The probability of inguinal node metastasis in patients with grade 1 tumors without perineural invasion is almost nonexistent whereas for high-grade tumors associated with perineural invasion is near 80%.

Abstract
OBJECTIVES To assess the accuracy of magnetic resonance imaging (MRI) as a local staging technique in penile cancer and its role in selecting patients for conservative surgical management. METHODS Fifty-five men diagnosed with invasive penile carcinoma on biopsy were locally staged with the use of MRI. Prostaglandin E1 (alprostadil) was injected into the corpora to induce an artificial erection. Radiologic staging was compared against final histopathologic stage of the tumour. Sensitivity, specificity, and kappa agreement values were calculated for each tumour stage. Additionally, corpora cavernosa involvement was reviewed in 20 consecutive cases and suitability for conservative surgery assessed. RESULTS A good correlation between radiologic and histologic staging was achieved with an overall kappa value of 0.75 (p<0.001). Stage-specific sensitivities and specificities were calculated: T1 (85%; 83%), T2 (75%; 89%), and T3 (88%; 98%). MRI accurately predicted corpora cavernosa invasion in all cases of pathologically proven disease. These patients were selected to undergo partial penectomy. There were no complications using this imaging technique. CONCLUSIONS This study demonstrates that penile MRI is highly accurate in the local staging of penile cancer. Associated improvements in surgical planning allow the provision of conservative surgical treatments over more radical procedures.

Abstract
OBJECTIVES Dynamic sentinel node biopsy (DSNB) has been performed at our department since 1994 to assess status of inguinal lymph nodes of clinically node-negative (cN0) patients with penile carcinoma. Over time, several modifications were made to reduce the false-negative rate and thus increase sensitivity. We compared the false-negative and complication rates of the current procedure, as performed at our institute since 2001, with the prior procedures. MATERIALS AND METHODS The patients who underwent DSNB for penile carcinoma in the period from 1994 until July 2004 were divided into two cohorts: cohort A: patients treated from 1994 until 2001; cohort B: patients treated from 2001 until 2004. Cohort A consisted of 92 patients, in whom 157 groins were explored. Cohort B consisted of 58 patients, with a total of 105 explored groins. Medians for follow-up in cohorts A and B were 83 (range: 24-130) and 30 (range: 24-49) mo, respectively. The false-negative and complication rates were determined in both cohorts. RESULTS In cohort A, 21 of 157 explored groins contained tumour-positive sentinel nodes, and five false-negative procedures were encountered, resulting in a false-negative rate of 19.2%. In cohort B, 20 of 105 explored groins contained tumour-positive sentinel nodes, and one procedure was false-negative. The false-negative rate was 4.8%. The rate of complications dropped from 10.2% in cohort A to 5.7% in cohort B. All complications were minor and transient. CONCLUSIONS The false-negative and complication rates of DSNB have decreased since the procedure was modified. The current procedure has false-negative and complication rates of 4.8% and 5.7%, respectively. DSNB has matured into a reliable and safe method for assessing status of lymph nodes in cN0 penile carcinoma patients.

Abstract
PURPOSE In penile cancer the therapeutic benefits of early inguinal lymphadenectomy must be counterbalanced by the high rates of morbidity, postoperative complications and mortality. A relevant aim is optimizing the selection of the patients who could really have the highest survival advantage from inguinal lymphadenectomy, limiting the cases in which this surgery might be considered over treatment with a risk of severe complications. We generated a nomogram estimating the risk of pathological inguinal lymph node involvement according to clinical lymph node stage and pathological findings of the primary tumor. MATERIALS AND METHODS We retrospectively collected the clinical and pathological data of 175 patients who had undergone surgical therapy for squamous cell carcinoma of the penis from 1980 to 2002 at 11 urological centers in northeastern Italy. A logistic regression model was used to construct the nomogram. RESULTS The presence of palpable groin lymph nodes and the histological findings of vascular and/or lymphatic embolization were important predictors of metastatic inguinal lymph node involvement. The nomogram predicting the risk of metastatic lymph node involvement showed a good concordance index (0.876) and good calibration. CONCLUSIONS The clinical stage of groin lymph nodes and pathological findings of penectomy specimens allowed us to generate a nomogram to predict the probability of metastatic lymph node involvement in patients with squamous cell carcinoma of the penis. The statistical model showed an excellent ability to identify the patients with lymph node metastases and good calibration.

Abstract
PURPOSE We created the first nomograms to predict cancer specific survival probabilities of patients with squamous cell carcinoma of the penis, clustering prognostic information from the most commonly used clinical and pathological variables. MATERIALS AND METHODS We retrospectively collected clinical and pathological data from 175 patients who had undergone surgery for squamous cell carcinoma of the penis from 1980 to 2002 at 11 urological centers in northeastern Italy. A logistic regression model was used to construct the nomogram. RESULTS At a median followup of 24 months, 101 patients (57.7%) were alive and disease-free while 74 (42.3%) died of penile cancer. According to multivariate analyses, 2 models predictive of cancer specific survival probability were generated. The first model was based on the pathological findings of the primary tumor after penectomy and on the clinical stage of groin lymph nodes, while the second model included the pathological data of the primary tumor and groin lymph nodes. The concordance index was 0.728 for the first model and 0.747 for the second. Calibration appeared to be good in both models. CONCLUSIONS In this article we propose 2 models to predict the 5-year cancer specific survival probabilities of patients with squamous cell carcinoma of the penis. Both models showed good discriminating power and calibration in predicting patient 5-year cancer specific survival. These nomograms could improve the quality of prognostic data provided to patients and support physicians in planning treatment.

Abstract
The assessment of penile cancer on the basis of clinical findings alone can often result in inaccurate staging and suboptimal treatment. Imaging of primary penile cancer and metastatic lymphadenopathy can help optimize planning of both primary tumor resection and treatment for lymph node metastases. Magnetic resonance (MR) imaging is the most accurate imaging modality in the assessment of primary penile cancers, which usually manifest as solitary, ill-defined infiltrating tumors that are hypointense on both T1- and T2-weighted MR images. T2-weighted MR imaging allows delineation of the tumor margin and of any extension into the penile shaft. On gadolinium-enhanced T1-weighted images, the tumors enhance to a greater extent than do the corpora cavernosa. In addition, the recently introduced technique known as lymphotrophic nanoparticle-enhanced MR imaging can help identify metastatic lymph node disease. However, further studies will be needed to determine the role of this imaging technique in clinical practice. Computed tomography does not clearly depict the local extension of primary penile cancer; however, it is useful in assessing metastases and postoperative complications.

Abstract
UNLABELLED Penile cancer, while relatively rare in the western world, remains a disease with severe morbidity and mortality, not to mention significant psychological ramifications. Furthermore, the disease is observed with dramatically increased incidence in other parts of the world. A review of the literature has shown that the overwhelming majority of penile cancers are in situ or invasive squamous cell carcinomas, including a well-differentiated variant, verrucous carcinoma. Important predisposing factors are lack of circumcision, human papillomavirus infections, and penile lichen sclerosus, although other factors have occasionally been reported as well. Prevention, careful monitoring of patients at risk, and early diagnosis are essential to reduce the incidence of penile carcinoma and to provide a definitive cure. Public health measures, such as prophylactic use of circumcision, have proved successful but are controversial. Also, no standard therapeutic guidelines as to the best treatment strategy according to different stages, including efficacy of conservative nonsurgical modalities and indications for lymph nodal dissection, are available so far. It is common opinion that penile cancer is an emerging problem that deserves further investigations, and physicians, especially dermatologists, should be aware of this issue. LEARNING OBJECTIVE At the completion of this learning activity, participants should be familiar with penile carcinoma, its risk factors, its clinical and histologic presentation, and the treatments currently available for its management.

Abstract
Cancer of the penis is rare in Europe, accounting for less than 0.5% of all cancers. Phimosis and poor hygiene are strong risk factors whereas neonatal circumcision is a contributing factor in the prevention of this disease. More than 95% of penile carcinomas are squamous cell carcinomas. Early disease (stage I-II) is curable in most patients, who can be treated by conventional penile amputation or, in selected cases, by organ preserving techniques, including Moh's micrographic surgery, laser ablation or radiation therapy (external-beam, brachytherapy). For more advanced primary tumours, penile amputation is required. Survival of patients with penile cancer is strongly related to the presence and extent of nodal metastases. Bilateral inguinal lymphadenectomy is recommended for palpable lymph nodes that persist 3 or more weeks after removal of the primary tumour and a course of antibiotic therapy. In patients with proven inguinal lymph node metastases, bilateral ileoinguinal dissection should be performed. When the nodes are clinically negative, "prophylactic" inguinal lymphadenectomy may be a reasonable approach in patients with invasive tumours (T2 or greater), high grade tumours, or tumours exhibiting vascular invasion. The role of chemotherapy, as adjuvant and neoadjuvant or primary treatment in metastatic disease, needs to be further explored in prospective clinical trials.

Abstract
BACKGROUND The objective of the current study was to identify independent clinical and pathologic variables that were predictive of lymph node involvement in patients with squamous cell carcinoma of the penis in a multicenter series with the intent to select patients who were suitable to undergo immediate inguinal lymphadenectomy. METHODS Data were analyzed from 175 patients who underwent surgery for penile carcinoma in 11 urologic centers participating in the Gruppo Uro-Oncologico del Nord-Est (Northeast Uro-Oncological Group) Penile Cancer Data Base. Pathologically positive lymph nodes were defined as the presence of histologically confirmed lymph node metastasis in patients who underwent either immediate or delayed inguinal and/or pelvic lymphadenectomy. Patients who had clinically positive lymph nodes with cytologically positive fine-needle aspiration results and who had not undergone lymphadenectomy were censored. RESULTS Overall, lymph-node involvement was observed in 71 of 175 patients (40.6%) included in the analyses. After analyzing the whole group of patients, the following variables were identified as independent predictors of pathologic lymph node metastasis: clinical lymph node status, pathologic stage of the primary tumor, venous and lymphatic embolizations, and histologic grade. In the subgroup of patients with clinically negative lymph nodes, tumor thickness, histologic grade, lymphatic and venous embolizations, infiltration of both corpus spongiosum and urethra, and pathologic stage of the primary tumor (according to the 1997 TNM classification system) were predictive of lymph node involvement on univariate analysis. The generated logistic regression model showed that venous and/or lymphatic embolizations and infiltration of the corpus spongiosum and/or urethra were independent predictors of pathologic lymph node metastasis in patients with clinically negative lymph nodes. CONCLUSIONS Venous and/or lymphatic embolizations played relevant roles as predictors of pathologic lymph node involvement in patients with penile neoplasia and should be considered important parameters in determining which patients with clinically negative lymph nodes should undergo immediate lymphadenectomy.

Abstract
Surgeons often perform small or superficial penile biopsies that are difficult to classify definitely with regard to a benign or malignant nature, and if malignant, cannot always be accurately subclassified. Staging and therapeutic decisions rely on the identification, in these materials, of pathologic parameters related to prognosis. In this study, we evaluated the accuracy and completeness of pathologic information obtained from biopsies of 57 consecutive patients with squamous cell carcinoma (SSC) of the penis, and compared it with the information obtained from penectomies. Diagnostic accuracy was determined by recording discordances of critical factors in biopsies and penectomies. The evaluated parameters were as follows: cancer diagnosis, histologic type, tumor grade, depth of invasion (anatomical levels), and vascular invasion. Histologic subtypes of SCC were the following: usual 37, verruciform 11, mixed 7, pseudohyperplastic 1, and sarcomatoid 1. Grades were 1, 2, and 3 (well, moderately and poorly differentiated). Levels of invasion were lamina propria, corpus spongiosum, and corpus cavernosum in the glans; and lamina propria, dartos, and skin in the foreskin. In 2 patients with well-differentiated tumors a diagnosis of cancer could not be established in biopsy material. In 17 cases (30%) there was a biopsy-penectomy discordance of histologic types, especially of verruciform and mixed carcinomas. Biopsies failed to identify the correct histologic grade in 30% of the cases. A higher grade was usually identified in penectomy specimens. Because biopsies were superficial, the deepest point of invasion could not be determined in 91% of the cases. Vascular invasion was identified in biopsies in only 1 of 8 patients. In summary, biopsies were useful for cancer diagnosis except in 2 differentiated variants of penile squamous cell carcinoma. However, important pathologic parameters related to prognosis were missed on biopsy materials, and they were more accurately evaluated in penectomy specimens. We conclude that clinical and pathologic staging of penile cancer, at least in our material, cannot depend on biopsy information alone. Data from biopsies may be insufficient to make a decision whether to perform a groin dissection, or for prognostic evaluation in those patients in whom other treatment modalities (such as radiotherapy or chemotherapy) are being considered.

Abstract
We present 10 cases of well-differentiated, squamous cell carcinoma of the penis with pseudohyperplastic features. At presentation, the median age was 69 years. Seven of the tumors were multicentric, and the majority preferentially involved the foreskin inner mucosal surface. Grossly the tumors were typically flat or slightly elevated, white and granular, and measured approximately 2 cm. Characteristic histologic features included keratinizing nests of squamous cells with minimal atypia surrounded by a reactive fibrous stroma. In biopsies or individual areas of resected specimens, the differential diagnosis with pseudoepitheliomatous hyperplasia was difficult but when samples of adequate size were available, obvious evidence of infiltration was present. The adjacent squamous epithelium typically showed changes that are known to be associated with squamous cell carcinoma ranging from squamous hyperplasia to low-grade, and in a few cases high-grade, squamous intraepithelial lesions. Well-developed lichen sclerosus was seen in all cases. Patients were treated by circumcision or partial penectomy. With the exception of 1 patient who developed a glans recurrence 2 years after initial circumcision, follow-up after the initial surgical procedure has been uneventful. The majority of penile carcinomas with the high degree of differentiation seen in these cases are in the category of the verruciform tumors, either the verrucous or papillary carcinoma, not otherwise-specified subtypes. Experience with the cases reported in this series indicates that a subset of nonverruciform, often multicentric, tumors with a high degree of differentiation and pseudohyperplastic features occur and preferentially involve the foreskin. Because it was present in all cases, lichen sclerosus may play a precancerous role.

Abstract
Recurrence in patients with penile carcinoma occurs in about one third of cases, usually due to insufficient surgery or positive resection margins. An evaluation of surgical resection margins in penectomy specimens was performed to determine precise anatomic sites of tumor involvement, hoping to advance knowledge concerning the local routes of spread of penile carcinomas. A pathologic study of 80 partial penectomies revealed 14 positive margins. Margins were examined after their separation from the main specimen as follows: 1) proximal urethra and surrounding tissues consisting of urethral epithelium with Litree glands, lamina propria, corpus spongiosum, and penile fascia (periurethral cylinder); 2) proximal shaft with corresponding corpora cavernosa separated and surrounded by the tunica albuginea and penile fascia; and 3) skin of shaft with underlying corporal dartos. In 9 patients, only one site was involved by carcinoma, and in 5 there were multiple contiguous sites (for a total of 20 anatomic sites). The distribution of the various sites involved by carcinoma was as follows: urethral epithelium, 4 cases (2 in situ and 2 invasive carcinomas including intraluminal spread); lamina propria, 5 cases; corpus spongiosum, 3 cases; penile fascia, 6 cases; and corpora cavernosa and skin, 1 case each. One of the in situ lesions was discontinuous with the main glans tumor, and the other one was continuous with it. The penile fascia was the most commonly involved site followed by the urethral lamina propria and epithelium. Dissemination to outer skin, corpora cavernosa, and corpus spongiosum was less frequent. The highly vascularized and innervated loose connective tissue of the penile fascia appears to facilitate tumor spread. The urethra is either a pathway for in situ tumor progression from glans to urethra or part of a field prone to malignant transformation. The infrequent involvement of corpora cavernosa is probably due to the tunica albuginea acting as a barrier preventing tumor spread. Based on these observations and the examination of hundreds of penectomy specimens, we are proposing five probable routes of local spread for penile cancer: 1) horizontal and superficially spreading from one epithelial mucosal compartment (glans, coronal sulcus, and foreskin) to the other; 2) following the penile fascia; 3) through spaces created by feeding vessels in the tunica albuginea; 4) vertical spreading involving step-by-step different penile anatomic compartments; and 5) along the urethral epithelium.

Abstract
Squamous cell carcinoma (SCC) is the most common tumor of the penis. The natural history and its proclivity to spread via regional lymphatics has been well defined. Laser ablation of the primary tumor has a prominent role in patients with a superficial tumor as a penis-conserving approach. Patients with deeper infiltrating tumors, should undergo (partial) penile amputation. For patients presenting with proven metastatic nodes complete (ilio-) inguinal lymphadenectomy should be performed. During the last two decades, the management of penile carcinoma patients with impalpable regional lymph nodes has improved due to better knowledge of risks for metastases, the introduction of modified lymphadenectomy, and sentinel node biopsy. Future perspectives in penile cancer comprises continuing research to reduce mutilation without jeopardizing clinical outcome.

Abstract
OBJECTIVES To evaluate the predictive role of primary tumor histopathological features in predicting inguinal lymph nodes involvement in patients with penile squamous cell carcinoma. MATERIAL AND METHODS We retrospectively analysed pathological records from 30 consecutive patients who underwent penectomy for invasive squamous cell carcinoma of the penis. All histological specimens were reviewed by the same pathologist. We considered the following histological parameters: histological grading, growth pattern, deph invasion, tumour thickness, nuclear grading, poorly differentiated cancer rate, vascular and lymphatic embolization, eosinophilic and mononuclear infiltration and pathological stage. RESULTS Lymph nodes involvement occurred in 5 patients who underwent 'early' lymphadenectomy and in other 4 ones during oncological surveillance. Lymph nodes metastasis resulted significantly correlated with histological grading (p = 0.005), lymphatic (p = 0.005) and venous (p = 0.02) embolization, corpora cavernosa (p = 0.03) and urethra (p = 0.03) infiltration. Histological grading and lymphatic embolization were independent predictive variables of lymph nodes involvement (p = 0.02). CONCLUSIONS The histological grading and lymphatic embolization have to be considered as important parameters to select patients with penile squamous cell carcinoma to undergo an 'early' lymphadenectomy.

Abstract
BACKGROUND Penile squamous cell carcinoma (SCC) may occur on pre-existing lesions of lichen sclerosus (LS). However, the prevalence of histological changes of LS in penile SCC is not well established. Moreover, mucosal oncogenic human papillomaviruses (HPVs) are sometimes detected in penile SCC, but have not been systematically sought in LS-associated penile SCC. OBJECTIVES To establish the prevalence of LS histological changes and of mucosal oncogenic HPV in a series of patients with penile SCC. METHODS Consecutive cases of histologically proven penile SCC from a single university hospital over a 14-year period were retrospectively selected and reviewed. Histological signs of LS were systematically sought. HPV was detected by polymerase chain reaction (PCR) amplification of DNA from paraffin-embedded skin samples using general primers GP5+/GP6+ (allowing detection of mucosal HPV) and oncogenic type 16-, 18-, 31- and 33-specific primers. RESULTS Eighteen cases of penile SCC were found. The mean +/- SD age of patients at diagnosis was 67.3 (14.5 years). In eight of 18 (44%) cases, SCC was associated with histological features of LS. Seventeen skin biopsy specimens of SCC (nine without and eight with LS histology) were subjected to PCR amplification for HPV. Mucosal HPV was detected in six of them (35%). Five of nine SCCs without histological features of LS were positive for mucosal HPV: three with HPV type 16 and two with only general primers. In contrast, all eight SCCs associated with LS were negative for oncogenic HPV types, although one was positive with general primers. CONCLUSIONS Penile SCC seems to be frequently associated with LS histological changes. As with vulval SCC, we found that non-LS-associated penile SCC tended to be frequently associated with oncogenic HPV infection, whereas LS-associated penile SCC was not. Larger series are needed to confirm this association.

Abstract
BACKGROUND Cancer of the penis is an uncommon malignancy in developed countries, but the incidence is as high as 17% of all male cancers in some undeveloped countries. The surgical management of this disease has improved due to better knowledge of risk for metastasis and newer imaging technologies to assess the regional lymph nodes. METHODS We review the literature on incidence, etiology, pathology, clinical presentation, staging, and management of penile cancer. We present our institutional experience with 160 patients who underwent extended ilioinguinal lymph node dissection, as well as with 7 patients who underwent a modified lymph node dissection. RESULTS Better understanding of pathologic features allow for stratification of patients into low, intermediate, or high risk for lymph node involvement. Lymphatic mapping to this stratification improves selection of patients who might benefit from lymph node dissection after excision of the primary lesion. Our experience with lymph node dissection yielded a high incidence of positive lymph nodes when lymphadenopathy was present. The recent use of a modified lymph node dissection has minimized morbidity. Current chemotherapy agents are ineffective in this disease. CONCLUSIONS Pathologic features of the primary lesion and the incorporation of lymphatic mapping have improved the selection of patients who might benefit from lymph node dissection. The use of a modified lymph node dissection in selected patients has decreased morbidity. Effective chemotherapy agents are needed in the management of advanced penile cancer.

Abstract
The ability to predict cancer progression may help the clinical management of patients with penile squamous cell carcinoma. We studied 22 cases of squamous cell carcinoma of the penis diagnosed between 1989 and 1998. The depth of invasion was measured from the basement membrane of the squamous epithelium to the deepest invasive cancer cells. Cancer progression was defined as the development of lymph node metastasis or distant metastasis. The mean patient age was 63 years and the mean follow-up was 28 months. Ten patients developed cancer progression. The mean depth of invasion among patients with cancer progression was 9.8 mM, as compared to the mean depth of invasion of 4.0 mM among those patients without cancer progression (P =.02). Vascular invasion was also predictive of cancer progression (P =.02). Metastases developed in the majority (6 out of 7) of cases invading more than 6 mM, but developed only in a minority (4 out of 15) of cases invading 6 mM or less. We conclude that depth of invasion and vascular invasion are significant predictors of cancer progression for penile squamous cell carcinoma.
