Organ sparing treatment for penile cancer using a 3D-printed high-dose-rate brachytherapy applicator.

PURPOSE: We present a case study of the treatment of localized squamous cell carcinoma on the glans penis with a custom-fabricated high-dose-rate (HDR) brachytherapy applicator. METHODS AND MATERIALS: A cylindrically shaped applicator was fabricated with eight embedded channels suitable for standard plastic brachytherapy catheters. An additional custom silicone bolus/sleeve was designed to be used with the 3D-printed applicator to provide an additional offset from the source to skin to reduce the surface dose and for patient comfort. RESULTS: The patient (recurrent cT1a penile cancer) underwent CT simulation, and the brachytherapy plan was created with a nominal prescription dose of 40 Gy in 10 fractions given bidaily to the surface, and 35 Gy at 5 mm depth. Dose coverage to the clinical target volume was 94% (D90). Most fractions were treated with only 5-10 min of setup time. Follow up visits up to 1 year showed no evidence of disease with no significant changes in urinary and sexual function and limited cosmetic detriment to the patient. CONCLUSIONS: Patient-specific organ-sparing HDR plesiotherapy using 3D printing technology can provide reliable and reproducible patient setup and may be effective in achieving disease control for superficial penile cancer, although preserving patient quality of life.

Dynamic Sentinel Lymph Node Biopsy for Penile Cancer: Accuracy is in the Technique.

OBJECTIVES: To demonstrate an operative standard for dynamic sentinel lymph node biopsy (DSLNB). Long-term survival in men with penile squamous cell carcinoma (SCC) depends on accurately staging lymph node metastases. European Association of Urology (EAU) and National Comprehensive Cancer Network (NCCN) guidelines recognize DSLNB as a standard for staging men with intermediate to high-risk tumors and clinically absent inguinal lymphadenopathy. DSLNB accuracy has been linked with pre-operative planning and surgical technique, yet no peer-reviewed video exists to establish an operative standard. Here we present a narrated video of our technique and discuss the accuracy of this approach using retrospective patient data. METHODS: Ethics approval and patient consent was obtained. Retrospective analysis was performed on patients undergoing DSLNB for inguinal lymph node staging of histologically proven penile SCC. Data was included from 2 experienced uro-oncologists with subspecialty training in penile cancer working in Victoria, Australia between January 2015 and July 2021. Variables collected included Primary tumour histology, DSLNB pathology, progression to radical inguinal lymph node dissection (RILND) and recurrence patterns. DSLNB sensitivity and proportion of groins spared RILND is calculated. RESULTS: DSLNB was performed on 127 groins (64 patients) during the study period. Within the cohort, 44% (n = 28) of patients had a pre-operative lymphoscintigraphy with single-photon emission computed tomography (SPECT/CT). Analysis of primary tumor intervention demonstrates that 82.8% (n = 53) of men underwent penile sparing surgery. Tumor histology in 88% of patients (n = 56) demonstrated pT1-pT2 disease. Overall n = 19 groins undergoing DSLNB were positive for malignancy and n = 108 were negative. 36 groins progressed to RILND during a mean follow up of 29 months. Only 2 groins that previously had a negative DSLNB were positive on RILND, one in the groin and one in the pelvis. We observed a false negative rate of 1.9% and a sensitivity of 90.5%. In our cohort DSLNB allowed 71.7% of groins to proceed for surveillance instead of prophylactic radical ILND. CONCLUSIONS: DSLNB is a safe and accurate method for assessing inguinal lymphadenopathy in men with intermediate to high-risk penile SCC and impalpable groins. This video study establishes an operative standard for DSLNB with oncological outcomes are consistent with international expectations. Standardized use of DSLNB by an experienced team will reduce morbidity while maintaining oncological safety for men with intermediate to high-risk penile cancer and cN0 disease.

Microsurgical treatment of lower extremity lymphedema: A multidisciplinary approach to improve morbidity in advanced penile cancer patients.

INTRODUCTION: Lower extremity lymphedema is a major source of morbidity in up to 70% of penile cancer patients. Lymphedema is often thought to be incurable, though surgical treatments have started to emerge. This study is the first to apply lymphovenous bypass specifically to penile cancer patients status post lymphadenectomy. METHODS: We performed microsurgical lymphovenous bypass in 3 patients who underwent inguinal lymphadenectomy for advanced penile cancer, and later lymph node transplant in 1 patient. RESULTS: The lymphovenous bypass was performed by a trained microsurgeon: Two patients were treated as outpatients for lymphedema, and 1 patient underwent prophylactic lymphovenous bypass simultaneously with initial lymphadenectomy. We saw significant improvement in patient's clinical lymphedema as well as lymphatic drainage on infared imaging for 2 of 3 patients at 12 months, however 1 of these patients did require later lymph node transfer at 24 months. CONCLUSION: This early proof of concept study shows that these procedures should be considered and studied further in the treatment and prevention of debilitating lymphedema in the penile cancer population.

Adherence to European Association of Urology and National Comprehensive Cancer Network Guidelines Criteria for Inguinal and Pelvic Lymph Node Dissection in Penile Cancer Patients-A Survey Assessment in German-speaking Countries on Behalf of the European Prospective Penile Cancer Study Group.

BACKGROUND: Urologists' adherence to European Association of Urology and National Comprehensive Cancer Network guideline recommendations to perform inguinal (ILND) and pelvic (PLND) lymph node dissection in penile cancer (PC) patients is not known. OBJECTIVE: To assess a German-speaking European cohort of urologists based on their criteria to perform ILND and PLND in PC patients. DESIGN, SETTING, AND PARTICIPANTS: A 14-item survey addressing general issues of PC treatment was developed and sent to 45 clinical centers in Germany (n = 34), Austria (n = 8), Switzerland (n = 2), and Italy (n = 1). INTERVENTION: Two of the 14 questions assessed the criteria to perform ILND and ipsilateral PLND. OUTCOME MEASUREMENTS AND STATISTICAL ANALYSIS: Correct responses for ILND and PLND criteria were assessed. Based on a multivariate logistic-regression-model, criteria independently predicting guideline adherence were identified. RESULTS AND LIMITATIONS: In total, 557 urologists participated in the survey, of whom 43.5%, 19.3%, and 37.2% were residents in training, certified, and in leading positions, respectively. ILND and PLND criteria were correctly identified by 35.2% and 23.9%, respectively. Of the participants, 23.3% used external sources for survey completion. The use of auxiliary tools (odds ratio [OR] 1.57; p[bootstrapped] = 0.028) and participants outside of Germany (OR 0.56; p[bootstrapped] = 0.006) were predictors of ILND guideline adherence. The number of PC patients treated yearly (p = 0.012; OR 1.06) and the use of auxiliary tools (p < 0.001; OR 5.88) were predictors of PLND adherence. Department size, healthcare status, professional status, and responsibility for PC surgery did not predict endpoints. Limitations include sample size and results in comparison with retrospective studies. CONCLUSIONS: Our results demonstrate overall suboptimal knowledge of the correct indications to perform ILND and PLND in PC patients among the surveyed urologists. We propose that governments and healthcare providers should be encouraged to centralize PC management. PATIENT SUMMARY: The management of inguinal and pelvic lymph nodes is crucial for the survival of penile cancer patients. Disease rarity mandates referral to clinical practice guidelines for appropriate treatment selection.

What are the unmet supportive care needs of men affected by penile cancer? A systematic review of the empirical evidence.

PURPOSE: To systematically evaluate evidence regarding the unmet supportive care needs of men affected by penile cancer and their partners to create a holistic model of care and inform clinical practice guidelines. METHODS: We searched CINAHL, MEDLINE, PsychINFO, Embase, and the Cochrane Library (CCRT and CDSR) controlled trials databases and clinicaltrial.gov from 1990 to April 2020. This review was reported according to the Preferred Reporting Items for Systematic Review and Meta-analysis (PRISMA) statement. RESULTS: 18 articles were included, reporting the results from 17 studies. Included reports used qualitative (seven studies) and survey (ten studies). Across these studies, men reported that the diagnosis and subsequent treatment of penile cancer affected physical, psychological and sexual well-being with each facet impacting and being intertwined with the other at varying degrees. There was varying complexity of unmet needs in men and partners pre-surgery, post-surgery and into survivorship. CONCLUSIONS: Moderate evidence exists that men affected by penile cancer experience a range of unmet supportive care needs across the international literature. Further work to evaluate the impact of penile cancer on partners is required.

Role of MRI in Staging of Penile Cancer.

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.

Making surgery safer by centralization of care: impact of case load in penile cancer.

PURPOSE: Penile cancer is a rare but aggressive disease, often requiring a rapid and extensive surgical treatment of the primary tumor and staging or treatment of the inguinal lymph node basins. Current management and guidelines of the disease are mainly based on retrospective data, as there is a lack of controlled trials or large series. The purpose of this work is to review contemporary data on the impact of centralization and formation of rare disease networks on penile cancer care and outcomes. METHODS: This narrative, non-systematic review is based on publications retrieved by a PubMed and EMBASE search and on the current guidelines of the European Association of Urology, the National Institute for Health and Care Excellence, and the National Comprehensive Cancer network. RESULTS: The low case load, particularly in non-specialized centres, combined with limited evidence regularly results in a disparity between the treatment strategy and the guidelines. The suboptimal guideline adherence is specifically the case for organ-sparing surgery and surgical staging of the groin areas in selected cases. Treatment of the disease in high-volume referral centres has been shown to improve the use of organ-sparing surgery, the utilization of invasive lymph node staging in high-risk patients, and finally has resulted in increased survival rates. CONCLUSIONS: The management of penile cancer in disease networks and in countries where centralized healthcare is offered positively influences functional and oncological outcomes. We propose that governments and health care providers should be encouraged to centralize healthcare for rare tumors such as penile cancer.

Leukemoid reaction: a rare paraneoplastic event in a case of advanced penile cancer and its management.

Leukemoid reaction is a paraneoplastic phenomenon associated predominantly with solid tumours. Malignancies presenting with leukemoid reaction have a grave prognosis. It is defined as persistent neutrophil count greater than 50×103 cells/µL. We report a case of leukemoid reaction in a patient with metastatic penile cancer. A 60-year-old man with partial penectomy status for squamous cell carcinoma of penis on neoadjuvant chemotherapy, presented with left fungating inguinal lymphadenopathy and total leucocyte count 96×103 cells/µL and hypercalcaemia. Leucocytealkaline phosphatase (LAP) score was excessively elevated. The patient underwent left ilioinguinal block dissection along with vastus lateralis flap for defect reconstruction. Postoperatively, the neutrophil counts and serum calcium level normalised. The patient improved clinically and was discharged.

Recent developments in penile cancer imaging.

PURPOSE OF REVIEW: This review discusses new findings in penile cancer imaging in relation to the European Association of Urology and National Comprehensive Cancer Network guidelines. RECENT FINDINGS: For imaging in penile cancer patients who are candidates for organ-sparing primary treatment, ultrasound with Doppler seems to be the method of choice in addition to physical examination. The sentinel node biopsy (SNB) procedure is used to detect small nodal metastases in clinically node-negative patients. In recent years, this procedure has been enhanced by 3D imaging using single photon emission computed tomography (SPECT) with computed tomography (CT) to improve preoperative localization and interpretation of sentinel nodes, as well as hybrid fluorescent and radioactive tracers to increase intraoperative localization of sentinel nodes. 18F-fluorodeoxyglucose PET (FDG-PET) with CT appears to be mainly useful for pelvic and distant staging in clinically node-positive patients. Other modalities with a potential future role in penile cancer are ultrasound with shear wave elastography, FDG-PET with MRI and ultrasmall paramagnetic iron oxide-enhanced MRI. SUMMARY: Imaging modalities in penile cancer have advanced throughout the years, assisting in treatment decision-making and during invasive procedures.

Penile cancer epidemiology and risk factors: a contemporary review.

PURPOSE OF REVIEW: Our objective is to present an overview of epidemiologic, clinical, and molecular risk factors with a focus on contemporary literature. RECENT FINDINGS: Penile cancer is a rare and aggressive neoplasm that accounts for less than 1% of male malignancies in the United States. Geographical disparities in incidence of disease are evident with high rates concentrated in the developing world (2.8-6.8 per 100 000) where neonatal circumcision is low and socioeconomic conditions predispose patients to multiple risk factors. Western countries have a significantly lower incidence and can be as low as 0.3 per 100 000. Many risk factors have been identified including lack of circumcision, phimosis, balanitis, obesity, lichen sclerosus, smoking, and psoralen UV-A phototherapy. In addition, human papilloma virus (HPV) has been linked to nearly 40% of cases and molecular mediators continue to be investigated. SUMMARY: Although Penile cancer can be a debilitating disease, several of the known risk factors are modifiable. Public health campaigns aimed to increase awareness, promote better hygiene, and deploy HPV vaccines have had varied success at decreasing disease burden. Focus should be placed on implementing such interventions in developing countries and at-risk populations.

The Diagnosis and Treatment of Penile Cancer.

BACKGROUND: The incidence of penile cancer in Europe lies in the range of 0.9 to 2.1 cases per 100 000 persons per year. Carcinogenesis is associated with human papilloma virus (HPV) infection and with chronic inflammation. METHODS: This review is based on publications (2010-2017) retrieved by a selective search in PubMed and EMBASE and on the guidelines of the European Association of Urology, the European Society of Medical Oncology, the National Comprehensive Cancer Network, and the National Institute for Health and Care Excellence (NICE). RESULTS: 95% of cases of penile cancer are accounted for by squamous cell carcinoma, whose numerous subtypes have different clinical courses. Chronic preputial inflammation due to phimosis or lichen sclerosus is often associated with penile cancer. Circumcision lowers the risk of penile cancer (hazard ratio: 0.33). Maximally organ-preserving surgery with safety margins of no more than a few millimeters is the current therapeutic standard, because a local recurrence, if it arises, can still be treated locally with curative intent. Local radiotherapy can be performed in early stages. Lymphogenic metastasis must be treated with radical lymphadenectomy and adjuvant chemotherapy. Patients with clinically unremarkable inguinal lymph nodes nonetheless need invasive lymph node staging because of the high rate of lymphogenic micrometastasis. CONCLUSION: Penile cancer is curable in all early stages with the appropriate treatment, but its prognosis depends crucially on the proper management of the regional (i.e., inguinal) lymph nodes. In many countries, the treatment of this rare disease entity has been centralized.

Treatment Trends and Outcomes for Patients With Lymph Node-Positive Cancer of the Penis.

Importance: Penile cancer is an uncommon disease with minimal level I evidence to guide therapy. The National Comprehensive Cancer Network (NCCN) guidelines advocate a lymph node dissection (LND) or radiotherapy with consideration of perioperative chemotherapy for all patients with lymph node-positive (LN+) penile cancer without metastasis. Objectives: To determine temporal trends in use of chemotherapy for patients with LN+ penile cancer without metastasis and to evaluate outcomes between those who did or did not receive LND, chemotherapy, and radiotherapy. Design, Setting, and Participants: The US National Cancer Database (NCDB) was queried for all 1123 patients with LN+, squamous cell carcinoma of the penis without metastasis from January 1, 2004, through December 31, 2014. Temporal trends were assessed using Cochran-Armitage tests. Multivariable logistic models were used to examine the association between treatments, clinicopathologic variables, and receipt of chemotherapy. Kaplan-Meier analyses with log-rank tests and multivariable Cox regressions were used to analyze overall survival. Data were analyzed between January 2017 and September 2017. Main Outcomes and Measures: Use of chemotherapy over time. Survival outcomes by receipt or nonreceipt of LND, radiotherapy, and chemotherapy. Results: Of 1123 patients identified, most were white (924 [82.3%]) vs African American (141 [12.6%]) or of other or unknown race (58 [5.2%]). The age of most patients (727 [64.7%]) was between 50 and 75 years, and 750 patients (66.8%) underwent an LND. From 2004 to 2014, the use of systemic therapy significantly increased (26 of 68 patients, 38.2% vs 65 of 136, 47.8%; P < .001). However, only 177 of 335 patients with N3 disease (52.8%) received chemotherapy (N1: 106 of 338, 31.4%; N2: 178 of 450, 39.6%). Following adjustment, older patients (>76 years: OR, 0.28; 95% CI, 0.15-0.50; P < .001) were less likely to receive chemotherapy. Patients who received radiotherapy (OR, 4.38; 95% CI, 3.10-6.18; P < .001) and those patients with N2 (OR, 1.62; 95% CI, 1.16-2.27; P = .005) or N3 (OR, 2.32; 95% CI, 1.67-3.22; P < .001) cancer were more likely to receive chemotherapy. On multivariable analysis, LND (HR, 0.64; 95% CI, 0.52-0.78; P < .001) was associated with better overall survival, while neither chemotherapy (HR, 1.01; 95% CI, 0.80-1.26; P = .95) nor radiotherapy (HR, 0.85; 95% CI, 0.70-1.04; P = .11) was associated with overall survival. Conclusions and Relevance: In hospitals reporting to the NCDB, only 66.8% of patients with LN+ penile cancer received an LND. While chemotherapy use has increased since 2004, rates remain low (52.8% for patients with N3 cancer). Receipt of LND, but not chemotherapy or radiotherapy, is associated with overall survival. This may reflect the aggressive natural history of penile cancer as well as the inherent analysis limitation of a relatively small sample size. These data highlight opportunities to improve adherence to guideline-recommended care.

Unusual Case of Diffuse Penile Metastasis of Prostate Cancer on 68Ga PSMA PET/CT Imaging and 177Lu PSMA Posttherapy Scintigraphy.

An 85-year-old man with prostate cancer for metastatic workup underwent Gallium Prostate-Specific Membrane Antigen (Ga-PSMA) PET/CT (Ga-PSMA PET/CT), which revealed unusual tracer uptake in the shaft and glans of penis as well as multiple systemic metastases in liver, skeletal, and lymph nodes. The penile lesion was proved to be metastatic adenocarcinoma from prostate on fine needle aspiration cytology. The patient underwent Lutetium (Lu)-labeled PSMA radioligand therapy, which also revealed diffuse tracer uptake in the penile shaft as well as other metastatic sites.

Differences in Survival Associated with Performance of Lymph Node Dissection in Patients with Invasive Penile Cancer: Results from the National Cancer Database.

PURPOSE: Inguinal lymphadenectomy remains under performed in patients with invasive penile cancer. Using a large national cancer registry we assessed temporal trends in inguinal lymphadenectomy performance and evaluated the impact of the procedure on survival in patients in whom inguinal lymphadenectomy was an absolute indication (T1b-4 N0/x-1) according to NCCN® (National Comprehensive Cancer Network®) Guidelines®. MATERIALS AND METHODS: We queried the National Cancer Database for all cases of nonmetastatic, T1b-4 N0/x-1 squamous cell carcinoma of the penis from 2004 to 2014. Multivariable logistic regression models adjusting for patient, demographic, and clinicopathological characteristics were used to examine the association between available covariates and receipt of inguinal lymphadenectomy. Cox proportional hazards regression analysis was then done to assess the impact of clinical and pathological variables on overall survival. Propensity score weighted analysis was performed to assess the effect of inguinal lymphadenectomy on overall survival. RESULTS: A total of 2,224 patients met analysis criteria, of whom 606 (27.2%) underwent inguinal lymphadenectomy. Following adjustment the procedure was more likely in younger patients, those who presented with palpable adenopathy (cN1), those treated at an academic facility and those with a more contemporary diagnosis. On survival analysis controlling for all known and measured confounders inguinal lymphadenectomy was associated with improved overall survival (HR 0.79, 95% CI 0.74-0.84, p <0.001). CONCLUSIONS: At hospitals that report to the National Cancer Database the overall rate of inguinal lymphadenectomy in patients with invasive penile cancer was only 27.2%. Inguinal lymphadenectomy was associated with increased overall survival, justifying the procedure as an important quality metric for performance reporting in patients with invasive penile cancer.

Successful downstaging of locally recurrent penile squamous cell carcinoma with neoadjuvant nanosomal docetaxel lipid suspension (NDLS) based regimen followed by curative surgery.

Penile squamous cell carcinoma (pSCC) is a relatively rare disease in Western world but is a significant health problem in developing countries like India. We report here a case of successful multimodality management of recurrent pSCC with pelvic lymphadenopathy in a 56-year-old male patient with poorly controlled diabetes. The patient presented with ulceroproliferative growth over the residual penile stump clinically involving root of penis and with right pelvic lymphadenopathy. The patient had a history of partial penectomy done elsewhere 20 months ago. In view of the comorbidities, locally recurrent disease and presence of right Iliac lymphadenopathy, the patient was treated with nanosomal docetaxel lipid suspension (NDLS), cisplatin and 5-fluorouracil (TPF regimen) in the neoadjuvant setting followed by staged surgical resection. This is the first case report showing successful treatment of recurrent pSCC with NDLS-based TPF regimen in the neoadjuvant setting followed by staged surgery in a patient with poorly controlled diabetes.

Patterns of Regional Lymphadenectomy for Clinically Node-negative Patients With Penile Carcinoma: Analysis From the National Cancer Database From 1998 to 2012.

PURPOSE: Evidence supports upfront regional lymphadenectomy (rND) when primary penile tumors exhibit high-risk features and negative inguinal adenopathy (cN0). We sought to analyze trends in the utilization of early rND as well as assess factors associated with its use and survival outcomes using a nationwide cancer registry database. PATIENT AND METHODS: The National Cancer Database was queried for patients with clinically nonmetastatic penile carcinoma and available nodal status who underwent rND from 1998 to 2012. Temporal trends in the utilization of early rND for those with cN0 disease were analyzed, and a multivariable logistic regression model was used to identify predictors for receiving rND. Survival analysis based on rND status was performed using the Kaplan-Meier method and Cox proportional hazard regression. RESULTS: From 1919 patients with available clinicopathologic variables, performance of early rND was documented in 377 (19.6%) patients with an increase in utilization over time (P = .001). The increase was driven by academic and comprehensive cancer programs compared with community programs (P < .001). Positive predictors were treatment facility, clinical tumor stage, and grade (all P < .05). African American patients (odds ratio [OR], 0.53; 95% confidence interval [CI], 0.33-0.86; P = .01) and those aged > 75 years (OR, 0.42; 95% CI, 0.26-0.68; P < .001) were significantly less likely to receive rND. Early rND was associated with improved overall survival (hazard ratio [HR], 0.67; 95% CI, 0.52-0.87; P = .003). CONCLUSION: There was increased use of early lymphadenectomy for patients with cN0 penile cancer driven by comprehensive and academic cancer programs. The study demonstrated demographic and socioeconomic differences that can help identify barriers to care for patients with penile cancer in the United States.
