Background: The use of organ sparing strategies to treat penile cancer (PC) is currently supported by evidence that has indicated the safety, efficacy and benefit of this surgery. However, radical penectomy still represents up to 15–20% of primary tumor treatments in PC patients. The aim of the study was to evaluate efficacy in terms of overall survival (OS) and disease-free survival (DFS) of radical penectomy in PC patients.

Methods: Data from a retrospective multicenter study (PEnile Cancer ADherence study, PECAD Study) on PC patients treated at 13 European and American urological centers (Hospital “Sant’Andrea”, Sapienza University, Roma, Italy; “G.D’Annunzio” University, Chieti and ASL 2 Abruzzo, Hospital “S. Pio da Pietrelcina”, Vasto, Italy; Department of Genitourinary Oncology, Moffitt Cancer Center, Tampa, FL, USA; Hospital of Budapest, Hungary; Department of Emergency and Organ Transplantation, Urology and Andrology Unit II, University of Bari, Italy; Hospital “Spedali Civili”, Brescia, Italy; Istituto Europeo di Oncologia, University of Milan, Milan, Italy; University of Modena & Reggio Emilia, Modena, Italy; Hospital Universitario La Paz, Madrid, Spain; Ceara Cancer Institute, Fortaleza, Brazil; Virginia Commonwealth University, Richmond, VA, USA; Aristotle University of Thessaloniki, Thessaloniki, Greece; Maria Skłodowska-Curie Memorial Cancer Center, Warsaw, Poland) between 2010 and 2016 were used. Medical records of patients who specifically underwent radical penectomy were reviewed to identify main clinical and pathological variables. Kaplan-Meier method was used to estimate 1- and 5-year OS and DFS.

Results: Of the entire cohort of 425 patients, 72 patients (16.9%) treated with radical penectomy were extracted and were considered for the analysis. The median age was 64.5 (IQR, 57.5–73.2) years. Of all, 41 (56.9%) patients had pT3/pT4 and 31 (43.1%) pT1/pT2. Moreover, 36 (50.0%) were classified as pN1–3 and 5 (6.9%) M1. Furthermore, 61 (84.7%) had a high grade (G2–G3) with 6 (8.3%) positive surgical margins. The 1- and 5-year OS rates were respectively 73.3% and 59.9%, while the 1- and 5-year DFS rates were respectively 67.3% and 35.1%.

Conclusions: PC is an aggressive cancer particularly in more advanced stage. Overall, more than a third of patients do not survive at 5 years and more than 60% report a disease recurrence, despite the use of a radical treatment.

Penile cancer (PC) and its most common histopathological subtype, squamous cell carcinoma (SCC), are uncommon neoplasms in developed nations, ranging from 0.6 to 6.8 per 100,000 men (1,2), accounting for an estimated 0.2–0.4% of malignancies in men (1-5). Notwithstanding its low incidence, this cancer was diagnosed in 2018, in the United States, in more than 2,000 patients and was the cause of death in approximately 400 deaths (6,7).

This neoplasia when diagnosed could require aggressive treatment resulting in significant morbidity, with negative impact on quality of life, including its devastating role on the psychology and sexuality of patients (8-10).

Age at diagnosis, stage, histologic grade and subtype of the tumor, presence of perineural and lymphatic infiltration, lymph node (LN) involvement are considered prognosis-key issues (11,12).

The gold standard treatment for localized PC is surgery. Although in the case of premalignant conditions or PC early stages an organ sparing surgery (OSS) (glans resurfacing, laser ablation, topical agents, i.e., 5-fluorouracil and imiquimod, glansectomy, local excision) may be applicable, partial or radical/total penectomy with perineal urethrostomy combined with radical inguinal lymphadenectomy still remains the recommended option for locally advanced and advanced invasive disease (11,13-17).

The OSS is undoubtedly an attractive option, but is still underused because of a presumed high risk of local recurrence (18,19). Mossanen et al. questioned the use of radical penectomy for optimal oncological control supporting the idea that partial penectomy may ensure overlapping survival rates to radical approach (20). Moreover, Chipollini et al. focused on the need of an appropriate follow up program in patients of pT2 tumor treated with OSS (21). Despite general interest for expanding indications of OSS, radical penectomy still represents up to 15–33% of treatments offered to PC patients (18,22-24).

Due to the rarity of PC, without level 1 evidence, in the absence of prospective and randomized studies to guide decision making, it is difficult to exactly define the oncology efficacy of one surgical option over the others.

The objective of this retrospective multi-institutional international study is to present our overall experience with radical penectomy for SCC.


Study population and main characteristics of interest

Following approval by the local ethical committees we retrospectively reviewed the clinical notes of all patients with PC that underwent surgical treatment in 13 European and American Centers from 2010 to 2016 (Penile Cancer Adherence study, PECAD Study). Demographics, patient’s comorbidities, history of circumcision, site and size of the primary lesion and primary local therapy, LN management and histopathology data were collected and analyzed. The type of surgical procedure was decided upon after taking into consideration surgeon’s and patient’s preferences and the European Association of Urology (EAU) Guidelines on PC. No perioperative chemotherapy or postoperative radiation was used for the management of the penile lesions. Staging was performed using physical examination and cross-sectional imaging with computed tomography (CT) and/or magnetic resonance imaging (MRI). Histopathological reports were provided by local genitourinary pathologists and according to local institutional protocol and the American Joint Committee on Cancer (AJCC)/International Union Against Cancer (UICC) 2009 TNM Classification for stage and grade. Only SCC cases were considered. Follow-up was done with periodical physical examination and imaging according to stage and risk stratification for all patients

Survival endpoints

The main survival endpoint of the study was to describe disease-free survival (DFS) rates. Secondary endpoint was to describe overall survival (OS). We defined follow-up as the time interval between surgery and disease recurrence or death for any cause. For patients in whom none of the events occurred, we defined the follow-up time interval as the period from surgery to the last follow-up visit.

Statistical analysis

Descriptive statistics relied on median and interquartile range (IQR) to summarize quantitative data, while frequency and proportions summarized qualitative data. Kaplan-Meier method was used to estimate DFS and OS rates at 1 and 5 years. Cox proportional hazards model were used to estimate the hazard ratios of main predictors of disease recurrence.

All statistical analyses were performed using R Statistical Software (version 3.5.3; R Foundation for Statistical Computing, Vienna, Austria). All tests were two-tailed, and a P value <0.05 was considered indicative of a statistically significant association.


The PECAD registry included 481 patients. Of all 84 (17.4%) underwent radical penectomy. After applying inclusion and exclusion criteria, 72 patients were retained in the study cohort (we excluded those on whom we had no information on the grade of the tumor or lost on follow-up). The median age was 64.5 (IQR, 57.5–73.2) years. Of all, 43.1% were circumcised, approximately half of the patients had tumors localized both to the foreskin and glands (54.2%), while none of them had tumors located in the shaft (Table 1).

Moreover, just over half of patients harbored pT3/pT4 stages (56.9%). At presentation 55.6% of patients had palpable inguinal LN. Inguinal lymph node dissection (LND) was performed in 51 (70.8%) patients (with adherence to the EAU guidelines of 97%). One third of the patients who underwent LND harbored pN2 stage (30.0%).

At a median follow up of 11.7 months (IQR, 8.2–25.6), 29 (40.3%) patients experienced disease recurrence. Among them 11 (15.3%) local and 14 (19.4%) had a systemic recurrence. Thirteen (18.1%) patients underwent an adjuvant chemotherapy cycle while seven patients (9.7%) continued therapeutic plan with subsequent radiotherapy.

The 1- and 5-year DFS rates were 67.3%±6.3% and 35.1%±8.8%, respectively (Figure 1). In univariable analyses the only predictor of disease recurrence was the pN stage. Indeed, higher recurrence rates were recorded in pN2 [hazard ratio (HR): 3.5, 95% confidence interval (CI): 1.07–11.39, P=0.038] and pN3 (HR: 4.22, 95% CI: 1.04–17.12; P=0.043) patients, compared their pN0 counterpart. Overall, 19 (26.4%) patients died. The 5-year OS rates were 59.9%±7.9% (Figure 2).

The radical surgical approach in PC has historically been considered the gold standard in the subgroup of patients at intermediate and high risk (anatomical-pathological stage ≥ pT1) with it a not indifferent “baggage” in terms of mortality, morbidity, physical, psychological and sexual impact. This therapeutic choice is emerging, evaluating data available in the literature, as the first indication furthermore in a significant percentage of subjects classified as low grade, early stage or in case of precancerous lesions, therefore in a subset of possible candidates for a less mutilating and less aggressive approach such us organ-sparing surgery (OSS). Radical treatment option is going to represent therefore, up to 30% to date, particularly in non-reference centers, with low volume of PC patients (18,22-24). In recent years, therefore, it is not surprising that more and more interests and attentions have focused around the OSS of PC with all his arrows and weapons, ranging from laser therapy with neodymium-doped yttrium aluminum garnet or carbon dioxide mediums to OSS like Mohs surgery, circumcision, glansectomy, glans resurfacing or partial penectomy approach trying to expand the therapeutic window more and more in favor of this preservation techniques (18,21,25,26).

In our study we exported, from the total pool present in a larger database which counts 425 total subjects diagnosed with PC, the data of 72 patients treated in the first instance with radical surgery. Our work aimed at evaluating the effectiveness in terms of OS and DFS at 1 and 5 years, focusing on an average follow-up period of 11.7 months. Our data has exposed the aggressiveness and poor prognosis of this neoplasm, despite the use of a radical approach. The OS rate was only slightly higher than 59% at 5 years, with a 5-year DFS rate of just 35%. These results are in agreement with what reported by the current literature. Zhu et al. in their manuscript assessed the PC specific survival (PCSS) following conservative penile sparing surgery (PSS) and more aggressive surgery ranged from partial penectomy to radical and total penectomy in a population of 699 patients with PC stage pT1 (18), isolated from a total number of 1,292 patients with penile malignancies. In the 699 pT1 subgroup, 265 (37.9%) patients underwent local tumor excision (LTE) while the remaining 434 (62.1%) was offered the more aggressive partial/total penectomy. The overall cancer mortality (OCM) resulting in the subgroup of patients treated with an aggressive approach was 40.7% with a PC specific mortality (PCSM) of 11.7%, numbers not far from our results. In the study published by Patel et al. (26), the author analyzed 220 cases of Australian patients diagnosed with PC, extrapolating data from a large database, the Central Cancer Registry, from 2001 to 2009, also comparing the low volume centers of surgical procedures for PC, with more experienced centers and greater number of surgical interventions on this pathology. On the sample of the 220 patients, Radical penile procedures (partial or total penectomy) were performed in 70% of the cases. Manish I. Patel then divided the centers involved in “Teaching” and “Non-teaching” centers and low (<4 procedures in 10 years) and high (>4 procedures in 10 years) volume of surgical interventions. The “Non-teaching” hospitals, where almost all were low-volume centers of procedures/year, the number of radical procedures reached and exceeded the percentage of 73%, against 65% of the structures defined as “Teaching” in a non-statistically significant manner (P=0.07). Again, in this work, survival in terms of median OS and 5-year OS was assessed, resulting respectively at 86.1% and 70.6%, significantly higher value than that extrapolated from the study of Zhu et al. but not too far from the percentages obtained in our experience. In the retrospective study by Beech et al. of 2015 (23), the authors published their ten-year experience (2005–2015) on 42 patient PCs and a follow-up of 25 months; passing through the LN staging, the patients were stratified as clinically negative LNs (32 patients—cN0) and clinically positive nodes (10 patients—cN1). The surgical approach chosen was excisional biopsy in 29%, partial penectomy in 38% and total penectomy in 33% of cases. The OS was 60% in this case at 102 months.

Moreover, there is also the scientific microcosm that orbits this rare neoplasm; guidelines established on this cancer are constructed on a small number and methodologically weak publications result in low evidence level, weak degrees of recommendation and limited adoption of itself. We detected an adherence to the EAU guidelines of 71% for <T2 stage PC, in a Swedish study (22) and in percentage of 91.4% in a study that involved more of 6,000 patients, structured in the United States, based on National Comprehensive Cancer Network (NCCN) guidelines for the management of the primary tumor (27). It means we are still treating smaller penile tumors with more radical surgery than necessary.

LN staging and management is undoubtedly an important indicator of survival in PC. EAU guidelines suggest lymphadenectomy or biopsy of sentinel node (SN) in cN0 with pT1b, T2–T4, and in all case of cN1/cN2 (28-30). In literature only a low proportion of patients are really treated with LND. Reasons for this should probably due to the high rate of difficulty encountered in the procedural technique combined with the non-negligible mortality and morbidity (31). More recent studies however found an increase in LND rates (31). This is in line with the results of our study which showed a 70% percentage of approach with LND.

Our findings also have shown agreement with previously published data to consider and define the N stage as an important survival prognostic indicator, the strongest predictor of poor prognosis. In the Canadian experience of Beech at al. 10 patients presented with clinically palpable nodal disease; 3 were deemed inoperable and the remaining 7 underwent radical lymphadenectomy with 5 patients pN3 and 2 pN0. In the pN3 group, 4 died and the last survived 28 months before having a penile recurrence which led to a salvage total penectomy.

For all these reasons we considered the objective of focusing the attention on this setting of patients undergoing radical surgery to be valid and interesting. As for our knowledge of recent literature, this population-based study we presented is the first manuscript entirely focused on radical penectomy patients, extrapolated from a multicenter, international database, which certainly boasts a good number of examined patients.

The study in question certainly shows some limitations. One is certainly the heterogeneity of the PC patient sample in terms of stage, disease progression, surgical skills and learning curves in different phases within the different first surgeons involved in the procedures. However, this in relation to the character and multicentric print of the work that has enlisted 13 centers between Europe and America. The numeric sample of patients (analyzed retrospectively) may seem low but it is in our opinion valid considering the rarity of the tumor pathology of the PC. We have retrospectively considered only patients with the anatomo-pathological squamous cell histotype (SCC), which however appear to be the most frequent histotype in patients with PC. We found systemic recurrences in 14 patients (19.4%) but unfortunately, we don’t know where exactly systemic recurrences were found.

The importance of this study is twofold: on the one hand there is an objective confirmation of high mortality and recurrence of the disease despite a cruel and radical approach even to the minor stage neoplasia, on the other this puts in the spotlight the gap, still important between the various and numerous scientific evidence, the attractive and publicized “mini invasive” or OSS techniques and the actual practice of urological surgical centers, where radical intervention represents a therapeutic option over-used even outside the boundaries of the guidelines.


These findings of our multi-institutional experience confirm the poor prognosis and the aggressive pattern of this cancer in line with the data currently in the literature, also with a radical penectomy approach. Our data have shown that at 5 years, more than a third of patients do not survive and more than 60% report a disease recurrence, despite radical treatment and lymphadenectomy approach (that was carried out in more than 70% of patients). Furthermore, our data have highlighted and demonstrated that, to date, OSS techniques are more an attraction, a surgical mirage but not a real practical reality.
