Organ-preserving neodymium-yttrium-aluminium-garnet laser therapy for penile carcinoma: a long-term follow-up

Oncological Outcomes of Thulium-Yttrium-Aluminum-Garnet (Tm:YAG) Laser Ablation for Penile Cancer

OBJECTIVE

To report oncological outcomes after thulium-yttrium-aluminum-garnet (Tm:YAG) laser ablation for penile cancer patients.

MATERIALS AND METHODS

We retrospectively analyzed 71 patients with ≤cT1 penile cancer (2013-2022). All patients underwent Tm:YAG ablation with a RevoLix 200W continuous-wave laser. First, Kaplan-Meier plots and multivariable Cox regression models tested local tumor recurrence rates. Second, Kaplan-Meier plots tested progression-free survival (≥T3 and/or N1-3 and/or M1).

RESULTS

Median (interquartile range) follow-up time was 38 (22-58) months. Overall, 33 (50.5%) patients experienced local tumor recurrence. Specifically, 19 (29%) vs 9 (14%) vs 5 (7.5%) patients had 1 vs 2 vs 3 recurrences over time. In multivariable Cox regression models, a trend for higher recurrence rates was observed for G3 tumors (hazard ratio:6.1; P = .05), relative to G1. During follow-up, 12 (18.5%) vs 4 (6.0%) vs 2 (3.0%) men were retreated with 1 vs 2 vs 3 Tm:YAG laser ablations. Moreover, 11 (17.0%) and 3 (4.5%) patients underwent glansectomy and partial/total penile amputation. Last, 5 (7.5%) patients experienced disease progression. Specifically, TNM stage at the time of disease progression was: (1) pT3N0; (2) pT2N2; (3) pTxN3; (4) pT1N1 and (5) pT3N3, respectively.

CONCLUSION

Tm:YAG laser ablation provides similar oncological results as those observed by other penile-sparing surgery procedures. In consequence, Tm:YAG laser ablation should be considered a valid alternative for treating selected penile cancer patients.

Organ-sparing treatment for T1 and T2 penile cancer: an updated literature review

PURPOSE OF REVIEW

Penile cancer (PeCa) is an orphan disease due to its rare incidence in high-income countries. Traditional surgical options for clinical T1-2 disease, including partial and total penectomy, can dramatically affect patient's quality of life and mental health status. In selected patients, organ-sparing surgery (OSS) has the potential to remove the primary tumor with comparable oncologic outcomes while maintaining penile length, sexual and urinary function. In this review, we aim to discuss the indications, advantages, and outcomes of various OSSs currently available for men diagnosed with PeCa seeking an organ-preserving option.

RECENT FINDINGS

Patient survival largely depends on spotting and treating lymph node metastasis at an early stage. The required surgical and radiotherapy skill sets cannot be expected to be available in all centers. Consequently, patients should be referred to high-volume centers to receive the best available treatments for PeCa.

SUMMARY

OSS should be used for small and localized PeCa (T1-T2) as an alternative to partial penectomy to preserve patient's quality of life while maintaining sexual and urinary function and penile aesthetics. Overall, there are different techniques that can be used with different response and recurrence rates. In case of tumor recurrence, partial penectomy or radical penectomy is feasible, without impacting overall survival.

An update on treatment of penile cancer

Penile cancer is a rare malignancy, particularly in industrialized nations. In the United States, rates are approximately less than 1 per 100,000 men per year with just over 2000 new cases per year. However, there is significantly increased prevalence in developing nations, with limited treatment expertise and reduced access to care, further driving an unmet clinical need. The most noteworthy risk factor for penile cancer is the association with human papillomavirus infection, which may be present in up to 50% of all penile carcinomas. In addition to local primary tumor approaches, multimodality treatment strategies are vital to patients with clinical regional nodal disease, locally advanced disease. Presence and degree of lymph node involvement remains the most important prognostic factor and patients may benefit from multiple treatment strategies. Interim analysis data from the first randomized clinical trial is expected to yield results in mid/late 2024–early 2025. These treatment approaches include neoadjuvant chemotherapy, adjuvant therapy, including chemotherapy and radiation. Systemic therapy for distant recurrent or metastatic disease is primarily a platinum-based chemotherapy, however with poor overall response. As poor outcomes remain high, particularly in indigent populations, there remains an unmet need for these patients, particularly for high level randomized trials and novel therapeutics. In this review, we will highlight treatment updates for penile cancer. In addition to standard of care, we will review novel lines of therapies including immunotherapies and targeted therapies as well as sequencing approaches.

What Is the Most Effective Management of the Primary Tumor in Men with Invasive Penile Cancer: A Systematic Review of the Available Treatment Options and Their Outcomes

Context

The primary lesion in penile cancer is managed by surgery or radiation. Surgical options include penile-sparing surgery, amputative surgery, laser excision, and Moh’s micrographic surgery. Radiation is applied as external beam radiotherapy (EBRT) and brachytherapy. The treatment aims to completely remove the primary lesion and preserve a sufficient functional penile stump.

Objective

To assess whether the 5-yr recurrence-free rate and other outcomes, such as sexual function, quality of life, urination, and penile preserving length, vary between various treatment options.

Evidence acquisition

The EMBASE, MEDLINE, Cochrane Database of Systematic Reviews, Cochrane Central Register of Controlled Trials (CENTRAL; Cochrane HTA, DARE, HEED), Google Scholar, and ClinicalTrials.gov were searched for publications from 1990 through May 2021. Randomized controlled trials, nonrandomized comparative studies (NRCSs), and case series (CSs) were included.

Evidence synthesis

The systematic review included 88 studies, involving 9578 men from 16 NRCSs and 72 CSs. The cumulative mean 5-yr recurrence-free rates were 82.0% for penile-sparing surgery, 83.9% for amputative surgery, 78.6% for brachytherapy, 55.2% for EBRT, 69.4% for lasers, and 88.2% for Moh’s micrographic surgery, as reported from CSs, and 76.7% for penile-sparing surgery and 93.3% for amputative surgery, as reported from NRCSs. Penile surgery affects sexual function, but amputative surgery causes more appearance concerns. After brachytherapy, 25% of patients reported sexual dysfunction. Both penile-sparing surgery and amputative surgery affect all aspects of psychosocial well-being.

Conclusions

Despite the poor quality of evidence, data suggest that penile-sparing surgery is not inferior to amputative surgery in terms of recurrence rates in selected patients. Based on the available information, however, broadly applicable recommendations cannot be made; appropriate patient selection accounts for the relative success of all the available methods.

Patient summary

We reviewed the evidence of various techniques to treat penile tumor and assessed their effectiveness in oncologic control and their functional outcomes. Penile-sparing as well as amputative surgery is an effective treatment option, but amputative surgery has a negative impact on sexual function. Penile-sparing surgery and radiotherapy are associated with a higher risk of local recurrence, but preserve sexual function and quality of life better. Laser and Moh’s micrographic surgery could be used for smaller lesions.

Laser technology in urologic oncology

Laser technology has been used in Urology since the 80s with a lot of different applications in endoscopic and open surgery. With the developments of the technology and the introduction of new active medium and source of laser energy, this technology have become the gold standard not only in stone surgery but even in benign prostate enlargement (BPE) surgical treatment. Regarding urologic oncology, laser energy has now reached an important role in focal therapy and in conservative treatment. The possibility of having better functional outcomes without any relevant impact on oncological results led to an increased use of laser in penile surgery, with a significant mention in urological guidelines for this option. In urothelial cancers as well, both in conservative management of upper tract tumors that in the treatment of non muscle invasive bladder cancer, a clear role of these relatively new source of energy have been demonstrated. Finally, both in prostate that in renal cancer the strategy of focal therapy may take advantage from this precise and fine technology. In this review we analyzed and described the applications of laser energy in urological cancers with a specific focus on penile, urothelial and prostate cancer.

Penile-sparing surgery for patients with superficial or initially invasive squamous cell carcinoma of the penis: long-term oncological outcomes

PURPOSE

To report long-term oncological outcomes after penile-sparing surgery (PSS) for superficial (Ta-Tis) or initially invasive (T1) penile cancer patients.

METHODS

We retrospectively analysed 85 patients with Ta/Tis/T1cN0cM0 penile cancer (1996-2018). All patients underwent PSS: circumcision, excision or laser ablation. First, Kaplan-Meier plots and multivariable Cox regression models tested tumor recurrence rates (any local/regional/metastatic). Second, Kaplan-Meier plots depicted progression-free survival (≥T2 or N1-3 or M1 disease).

RESULTS

Median (IQR) follow-up time was 64 (48-95) months. Overall, 48 (56%) patients experienced tumor recurrence. Median (IQR) time to tumor recurrence was 34 (7-52) months. Higher recurrence rates were observed for Tis (65%) and T1 (64%), compared to Ta (40%), but these differences were not significant on multivariable Cox regression analyses (HR:2.0 with 95% CI [0.9-5.1] and HR:2.2 with 95% CI [0.9-5.9], respectively). Moreover, higher recurrence rates were observed for G2-3 tumors (74%), compared to G1 (57%), but these differences were not significant on multivariable Cox regression analyses (HR:1.6; 95% CI [0.8-3.2]). During follow-up, 15 (17.5%) vs. 18 (21.2%) vs. 10 (11.5%) patients underwent 1 vs. 2 vs. ≥3 PSS. Moreover, 26 (30.6%) and 4 (4.7%) men were treated with glansectomy and partial/total penile amputation due to local progression, tumor size or patient preference. Additionally, 24 (28%) men underwent invasive nodal staging. Last, 22 (25.9%) patients experienced disease progression. Median (IQR) time to disease progression was 51 (31-82) months.

CONCLUSION

Patients treated with PSS for newly diagnosed superficial or initially invasive squamous cell carcinoma of the penis should be informed about the non-negligible risk of tumor recurrence and disease progression over time. In consequence, strict follow-up protocols are needed.

Treatment Options and Outcomes for Men with Penile Intraepithelial Neoplasia: A Systematic Review

Penile intraepithelial neoplasia (PeIN) is a rare skin condition with potential to progress to invasive penile cancer. We performed a systematic review of treatment options and outcomes for PeIN. Topical agents showed response and recurrence rates of 40-100% and 20% for imiquimod, and 48-74% and 11% for 5-fluorouracil, respectively. Discontinuation of topical agents because of side effects was observed in 12% of cases. Response rates for laser therapies were 52-100%, with recurrence in 7-48% of cases and a change in penile sensitivity in 50%. Circumcision cleared preputial PeIN. Rates of recurrence after surgical treatment of glans PeIN were 25% for wide local excision, 4% for Mohs surgery, 5% for total glans resurfacing, and 10% for glansectomy. There are limited data on factors predictive of treatment response and on sequencing of treatment options. PATIENT SUMMARY: Several treatment options are available for men with precancerous lesions of the foreskin or glans. Close follow-up is necessary as lesions can recur or progress to invasive penile cancer.

Oncologic outcomes and subsequent treatment following organ sparing surgery for penile carcinoma: The University of Texas M.D. Anderson Cancer Center Experience

OBJECTIVES

To determine the oncologic outcomes of organ sparing surgery (OSS) for penile cancer and to determine the management of and risk factors for local recurrence at a tertiary referral center in the United States.

METHODS AND MATERIALS

Patients undergoing OSS from 1996 to 2018 at The University of Texas, MD Anderson Cancer Center were identified using a prospective database. Organ sparing procedures included: wide local excision (WLE; including circumcision and glans resurfacing), partial or total glansectomy, laser therapy, or OSS combined with laser ablation (i.e., laser combination). Clinical and pathologic data were collected for descriptive analysis. Recurrences (local and regional) were identified, and the association between overall and local recurrences was determined using Cox proportional hazards regression. Overall and recurrence free survival analyses were performed using Kaplan-Meier estimates.

RESULTS

A total of 129 patients undergoing OSS were identified with a median follow up interval of 28.0 months. The most common OSS was laser combination (38.8%), and 65.1% of patients presented with pTis or ≤pT1a disease. Twenty (15.5%) recurrences were identified, of which 17 (13.2%) were local and 3 (2.3%) were regional. There were no distant recurrences as the initial site of recurrence. The median time to local recurrence was 20.9 months, and 88.2% were identified within 5 years of surgery. Most (76.5%) local recurrences were successfully treated with further penile preservation without a detrimental impact on overall survival. Patients with pathologic Ta or T1a disease treated with laser or laser combination surgery were more likely to present with local recurrence.

CONCLUSION

OSS using a variety of techniques to achieve negative surgical margins provides long-term effective local control for localized penile cancer. Most local recurrences can be successfully treated with further penile preserving strategies and long follow-up is essential. Laser therapy or laser combination with OSS should be used with caution in patients with invasive penile cancer.

Update on organ preserving surgical strategies for penile cancer

With the passage of time, there has been a major paradigm shift in the surgical management of penile cancer from radical to organ preserving penile surgical techniques, with closer surgical margins which offer good oncological, cosmetic and functional outcomes with improved physical and psychosexual well-being. This article aims to provide an update of the current organ preserving surgical strategies for penile cancer.

Penile sparing therapy for penile cancer

Penile cancer is a rare malignancy with a reported incidence of 0.66–1.44 per 100,000 men, and a reported mortality of 0.15–0.37 per 10,000 men. Expert clinical examination and histological diagnosis from biopsy is required to determine the extent and invasion of disease, which is paramount in planning of appropriate treatment. Management of loco-regional penile cancer can be divided into management of primary tumour and management of regional lymph nodes. This review article will focus on the management of the primary penile tumour with particular focus on penile sparing therapies. The aim of primary penile tumour management is to completely remove the tumour whilst preserving as much organ function as possible. Preservation of the penis is important as it allows patients to maintain urinary and sexual function, as well as quality of life. With the majority of penile cancer confined to the glans and foreskin, most penile cancers can be managed with organ-preserving therapy. A wide variety of treatment options are available, and this review aims to describe each of the options including the reported oncological and functional outcome for the different therapies for penile cancer.

Progress on Management of Penile Cancer in 2020

OPINION STATEMENT

Management of penile cancer represents a challenge to urologic oncologists due to the disease's rarity and sparse data in the literature. Squamous cell carcinoma represents the most common histologic subtype of penile cancer. Penile cancer has a disastrous effect on patients' psychological and physical health. Penile cancer accounts for approximately 1% of cancer deaths in the USA annually. However, in recent years, the management of penile cancer has achieved marked progress in both diagnostic and therapeutic approaches with the intent to avoid radical surgeries. The traditional total penile amputation has been replaced by penile preserving procedures in many patients. Nowadays, total penile amputation (total penectomy) is preserved only for patients with proximal lesions. The introduction of minimally invasive surgical techniques in the management of penile cancer-infiltrated lymph nodes has been reported. Given the dismal prognosis with conventional cytotoxic therapies, new systemic therapies have been investigated in patients with locally advanced or metastatic penile cancer. Multiple studies have shown promising outcomes. All these efforts have resulted in a remarkable improvement in patient quality of life. The objectives of our review are to update clinicians on the advances in the management of penile cancer and to summarize the recent guidelines and recommendations.

Penile Sparing Techniques For Penile Cancer

Penile cancers are rare malignancies. Traditional surgical options, including partial and total penectomy, can dramatically affect a patient's quality of life and mental health. In select patients, penile sparing techniques (PST) have the potential to remove the primary tumor with comparable oncologic outcomes while maintaining penile length, sexual function, and urinary function. In this review, we aim to discuss the indications, advantages, and outcomes of the various PST currently available for men seeking an organ-preserving option for their penile cancer.

Organ-sparing surgery of penile cancer: higher rate of local recurrence yet no impact on overall survival

PURPOSE

To report on the oncological outcome of organ-sparing surgery (OSS) compared to (total or partial) penectomy regarding recurrence patterns and survival in squamous cell carcinoma (SCC) of the penis.

METHODS

This was a retrospective study of all patients with penile SCC and eligible follow-up data of at least 2 years at our institution. Patients with tumors staged ≥ pT1G2 underwent invasive lymph node (LN) staging by dynamic sentinel-node biopsy or modified inguinal lymphadenectomy. Radical inguinal lymphadenectomy was performed when LNs were palpable at diagnosis and in those with a positive LN status after invasive nodal staging. Follow-up visits were assessed, and local, regional and distant recurrences were defined and analyzed.

RESULTS

55 patients were identified with a mean follow-up of 63.7 months. Surgical management was OSS in 26 patients (47.2%) and partial or total penectomy in 29 cases (52.8%). Histopathological staging was: pTis (12.7%), pTa (16.3%), pT1a (18.2%), pT1b (5.5%), pT2 (29.1%) and pT3 (18.2%), respectively. Patients in the penectomy group were significantly older (mean 68 vs. 62 years; p = 0.026) with a higher rate of advanced tumor stage (≥ pT2: 44.8% vs. 11.5%; p = 0.002). The local recurrence rate was 42.3% (n = 11) following OSS compared to 10.3% (n = 3) after penectomy (p = 0.007). Kaplan-Meier curves showed no significant differences between the two groups regarding metastasis-free and overall survival.

CONCLUSIONS

OSS is associated with a higher local recurrence rate compared to penectomy, yet it has no negative impact on overall and metastasis-free survival.

Penile-sparing modalities in the management of low-stage penile cancer

Penile-sparing modalities are gaining widespread adoption for the management of low-stage penile cancer due to an increasing demonstration of sound oncologic, cosmetic, sexual, psychosocial, and quality of life outcomes. This review aims to provide a comprehensive overview of the respective treatment options in the armamentarium of the practicing urologist in dealing with this rare but problematic condition.

Role of perioperative dynamic sentinel node biopsy for cN0 penile cancer management: experience from an Italian tertiary referral center

PURPOSE

Inguinal lymphadenectomy (iLAD) reduces mortality in patients with cN0 penile cancer but yields high complication rates. Thus, its prophylactic role has been questioned and dynamic sentinel node biopsy (DSNB) was introduced to select men who should undergo the procedure. Our aim was to investigate the accuracy of a contemporary DSNB cohort.

METHODS

We performed a retrospective analysis of ≥T1 or ≥G2 cN0 penile cancer undergoing perioperative DSNB from June 2009 to June 2015 at a tertiary referral center. We excluded men with <18 months follow-up or with local recurrence after primary curative treatment. Complications were graded according to the Clavien-Dindo classification.

RESULTS

Thirty-five men underwent DSNB; 85.71% had ≤T2 penile cancer with ≤G2a histology. Per groin detection rate was 80% (scintigraphy being positive bilaterally in 60% and unilaterally in 20.0%). In no cases did DSNB prolong the postoperative course compared to primary surgery. Nine men (n = 15/109 nodes removed) had positive results, 8 of whom underwent iLAD. Among negative DSNB patients, 2 developed nodal penile cancer recurrence; none of them had node biopsy due to inconclusive scintigraphy. At a median follow-up of 42 months (interquartile range 30-78 months), if considering only men with scintigraphy detected inguinal nodes, per-patient sensitivity and specificity were 50% and 80% whereas positive predictive value and negative predictive value were 25% and 92.3%, respectively.

CONCLUSIONS

Perioperative DSNB is a safe procedure, yielding promising results when performed at a tertiary referral center. Future prospective large studies are needed to investigate how to optimize detection rate and reduce false-negative rates.

Laser ablation as monotherapy for penile squamous cell carcinoma: A multi-center cohort analysis

INTRODUCTION

Although the trend towards penile sparing therapy is increasing for penile squamous cell carcinoma, outcomes for laser ablation therapy have not been widely reported. We assessed the clinical outcomes of penile cancer patients treated with only laser ablation.

MATERIALS AND METHODS

A retrospective review was performed on 161 patients across 5 multi-center tertiary referral centers from 1985 to 2015. All patients underwent penile sparing surgery with only laser ablation for squamous cell carcinoma of the penis. Laser ablation was performed with neodymium-doped yttrium aluminum garnet or carbon dioxide. Overall and recurrence-free survival was calculated using the Kaplan-Meier method and compared with the log rank test.

RESULTS

A total of 161 patients underwent laser ablation for penile cancer. The median age was 62 (IQR: 52-71) years and median follow-up was 57.7 (IQR: 28-90) months. The majority of patients were pTa/Tis (59, 37%) or pT1a (62, 39%). Only 19 (12%) had a poorly differentiated grade. The 5-year recurrence-free survival was 46%. When stratified by stage, the 5-year local recurrence-free survival was pTa/Tis: 50%; pT1a: 41%; pT1b: 38%; and pT2: 52%. The inguinal/pelvic nodal recurrence was pTa/Tis: 2%; pT1a: 5%; pT1b: 18%; and pT2: 22%. There were no differences among stages with respect to recurrence-free survival (P = 0.98) or overall survival (P = 0.20).

CONCLUSION

Laser ablation therapy is safe for appropriately selected patients with penile squamous cell carcinoma. Due to the increased risk of nodal recurrence, laser ablation coupled with diagnostic nodal staging is indicated for patients with pT1b or higher.

National Trends and Predictors of Organ-sparing for Invasive Penile Tumors: Expanding the Therapeutic Window

INTRODUCTION

The purpose of this study was to analyze contemporary trends and predictors in the use of organ-sparing treatment (OST) for low-stage invasive penile tumors as well as to ascertain its impact on overall mortality (OM) in those with high-risk (pT2) disease.

PATIENTS AND METHODS

The National Cancer Data Base was queried for patients with clinically nonmetastatic penile cancer and available pathologic tumor (pT) and treatment data from 1998 to 2012. Independent predictors for performance of OST were analyzed. Multivariable Cox proportional hazard regression was used to identify factors of OM in a subset of patients with pT2 disease.

RESULTS

A total of 4231 patients with ≤ pT2cN0cM0 primary penile cancer were identified over a median follow-up of 39.6 months. Approximately 49% of patients received OST over the study period (P = .009). Older age, Hispanic ethnicity, urban counties, academic facilities, and pT2 disease were negative predictors for OST (all P < .05), whereas grade and years of diagnosis where associated with increased performance (P < .01). In subgroup analysis of pT2 patients, older age, black race, comorbidity, node status, and grade were associated with higher OM (all P < .05). When compared with radical penectomy, partial penectomy was associated with decreased OM (hazard ratio, 0.67; 95% confidence interval, 0.52-0.87; P = .002), whereas organ-sparing did not affect survival (hazard ratio, 0.83; 95% confidence interval, 0.52-1.31; P = .419) in these patients.

CONCLUSION

Ethnic and socioeconomic differences exist in the local management of penile tumors. No impact on OM was observed for those with high-risk cases treated with organ-sparing at intermediate follow-up. More studies are needed to evaluate oncologic efficacy of organ-sparing in carefully selected invasive penile tumors.

Laser Ablation for Cancer: Past, Present and Future

Laser ablation (LA) is gaining acceptance for the treatment of tumors as an alternative to surgical resection. This paper reviews the use of lasers for ablative and surgical applications. Also reviewed are solutions aimed at improving LA outcomes: hyperthermal treatment planning tools and thermometric techniques during LA, used to guide the surgeon in the choice and adjustment of the optimal laser settings, and the potential use of nanoparticles to allow biologic selectivity of ablative treatments. Promising technical solutions and a better knowledge of laser-tissue interaction should allow LA to be used in a safe and effective manner as a cancer treatment.

Organ Preservation Surgery for Carcinoma Penis

Carcinoma of the penis is not uncommon in India. A sizeable number of patients do not report to the doctors in fear of mutilation to the organ and hence subsequently end up with advanced disease. Many patients with T1 or T2 disease when carefully selected are amenable to organ-preserving penile procedures including surgery, topical therapy, laser, and radiation therapy. Identification of appropriate patients and institution of these treatments has been noted to produce oncologically comparable results to extirpative surgeries. In this article, we review the criteria to identify patients qualifying for organ-preserving treatments and also review outcomes with a variety of penile-preserving procedures.

Primary penile cancer organ sparing treatment

INTRODUCTION

Surgical treatment of penile cancer is usually associated with mutilation; alterations in self-esteem and body image; affecting sexual and urinary functions; and declined health-related quality of life. Recently, organ sparing treatment has appeared and led to limiting these complications.

MATERIAL AND METHODS

An extensive review of the literature concerning penile-preserving strategies was conducted. The focus was put on indications, general principles of management, surgical options and reconstructive techniques, the most common complications, as well as functional and oncological outcomes.

RESULTS

Analyzed methods, e.g.: topical chemotherapy, laser ablation therapy, radiotherapy, Moh's microscopic surgery, circumcision, wide local excision, glans resurfacing and glansectomy are indicated in low-stage tumors (Tis, Ta-T2). After glansectomy, reconstruction is also possible.

CONCLUSIONS

Organ sparing techniques may achieve good anatomical, functional, and psychological outcomes without compromising local cancer control, which depends on early diagnosis and treatment. Penile sparing strategies are acceptable treatment approaches in selected patients with low-stage penile cancer after establishing disease-risk and should be considered in this population.

Penile cancer and phallus preservation strategies: a review of current literature

Penile cancer is a rare malignancy in most developed nations but its management can have significant anatomical, functional and psychological effects in patients. Whilst total penectomy used to be widely practiced, it is associated with significant psychological consequences pertaining to body image and masculinity, with loss of sexual function and the ability to void upright. Recent advances in surgical techniques and technologies has allowed for many organ-sparing techniques with acceptable psychosexual and oncological outcomes. Factors to be considered in phallus preservation treatment include: local invasion, tumour stage and the ability to achieve complete oncological control. Topical chemotherapeutic agents, laser ablation, radiotherapy, Mohs micrographic surgery, glansectomy and partial penectomy have been frequently used to interfere as little as possible with functional anatomy without compromising local cancer control. The difficulty with these phallus-preserving techniques is the potential risk of disease recurrence both locally and distally. Providing that patients are suitable for penile-sparing therapy, have been informed adequately on risk of tumour recurrence and are willing to commit to rigorous close surveillance, good functional outcome as well as oncological control can be achieved.

Penile cancer

OBJECTIVES

To review the risk factors, prevention, treatment, and management of the patient with penile cancer.

DATA SOURCES

Publications; clinical experience.

CONCLUSION

Penile cancer is a rare malignancy in the United States, but is more common in developing countries. The disease is so uncommon in the United States that there are oncology nurses who have never cared for a patient with this diagnosis.

IMPLICATIONS FOR NURSING PRACTICE

With significant psychosocial implications for the patient with penile cancer and partner, it is important that the nurse have an understanding of the diagnosis, treatment, and care of these patients.

Male genital premalignant dermatoses

The spectrum of conditions affecting the penile skin is varied and ranges from simple, benign dermatoses to premalignant and malignant conditions. Recently, improved understanding of the aetiology and natural history of these conditions has shaped new treatment paradigms and a functional knowledge of dermatology, urology and genitourinary medicine is required to successfully diagnose and treat these men. In this article, we explore the common precancerous states that can lead to penile carcinoma and review the recent advances with regards to the molecular basis for these dermatoses and the treatments that may be most effective for these men.
