Initial symptoms and delay in patients with penile carcinoma

A Clinical Nomogram for Predicting Overall Survival in Patients With T1/T2 Penile Squamous Cell Carcinoma

BACKGROUND

To evaluate the overall survival (OS) and construct a nomogram to predict the OS of patients with penile squamous cell carcinoma (PSCC).

METHODS

This retrospective study analyzed data of patients with PSCC from the First Affiliated Hospital of Soochow University between 2012 and 2022. R software was used to explore factors influencing OS in PSCC. Kaplan-Meier method and log-rank test were employed for OS estimation. Univariate and multivariate Cox proportional hazards regression analyses were performed to identify these factors. A nomogram was created to identify the independent prognostic factors. The model was evaluated by concordance index, receiver operating characteristic (ROC) curves, and calibration plots.

RESULTS

A total of 159 patients with T1/T2 PSCC were included in the analysis. Patients with T2/N2 stage, older age, larger tumor size, high preoperative systemic immune-inflammation index (SII), and poor preoperative nutrition had a higher incidence of poor OS. Age, T/N stage, tumor size, and SII were identified as independent prognostic indicators. A prognostic nomogram was formulated, and its predictive accuracy for estimating OS in PSCC patients was validated through ROC curves and calibration plots.

CONCLUSION

The nomograms, based on age, T/N stage, tumor size, and high preoperative SII, provide a valuable tool for predicting 1-, 2-, and 3-year OS in patients with T1/T2 PSCC without distant metastases.

Urology consultants versus large language models: Potentials and hazards for medical advice in urology

Background

Current interest surrounding large language models (LLMs) will lead to an increase in their use for medical advice. Although LLMs offer huge potential, they also pose potential misinformation hazards.

Objective

This study evaluates three LLMs answering urology-themed clinical case-based questions by comparing the quality of answers to those provided by urology consultants.

Methods

Forty-five case-based questions were answered by consultants and LLMs (ChatGPT 3.5, ChatGPT 4, Bard). Answers were blindly rated using a six-step Likert scale by four consultants in the categories: 'medical adequacy', 'conciseness', 'coherence' and 'comprehensibility'. Possible misinformation hazards were identified; a modified Turing test was included, and the character count was matched.

Results

Higher ratings in every category were recorded for the consultants. LLMs' overall performance in language-focused categories (coherence and comprehensibility) was relatively high. Medical adequacy was significantly poorer compared with the consultants. Possible misinformation hazards were identified in 2.8% to 18.9% of answers generated by LLMs compared with <1% of consultant's answers. Poorer conciseness rates and a higher character count were provided by LLMs. Among individual LLMs, ChatGPT 4 performed best in medical accuracy (p < 0.0001) and coherence (p = 0.001), whereas Bard received the lowest scores. Generated responses were accurately associated with their source with 98% accuracy in LLMs and 99% with consultants.

Conclusions

The quality of consultant answers was superior to LLMs in all categories. High semantic scores for LLM answers were found; however, the lack of medical accuracy led to potential misinformation hazards from LLM 'consultations'. Further investigations are necessary for new generations.

Association between HPV infection and penile cancer and penile intraepithelial neoplasia: A retrospective observational study

BACKGROUND

Penile cancer is rising in most European countries. Several risk factors have been identified, namely human papillomavirus (HPV) infection. However, the exact role of HPV in penile cancer carcinogenesis is still unknown. Clarifying the contribution of HPV in penile cancer is crucial as it may improve prevention and treatment strategies.

OBJECTIVE

To describe the characteristics of patients with penile cancer and penile intraepithelial neoplasia (PeIN), evaluate the prevalence of HPV-DNA in tumour tissue and identify differences between patients with and without HPV-DNA.

METHODS

A retrospective observational study including patients with histological diagnosis of penile squamous cell carcinoma (SCC) or PeIN between 2012 and 2021 in a university hospital was carried out. HPV analysis was performed using Anyplex™ II HPV28 Detection that detects and identifies 28 HPV types. (sensitivity of 95.9%).

RESULTS

A total of 25 patients were included. Most of the tumours identified were invasive SCC (n = 11) and SCC in situ (PeIN 3) (n = 8). PeIN1/2 was found in the remaining six patients. HPV-DNA was tested in all tissue specimens and was detected in 18 of them. High risk HPV DNA was identified in all positive HPV samples, except one. HPV types included in the nonavalent HPV vaccine were identified in 16 of the 18 samples positive for HPV-DNA. Stratifying patients according to HPV-DNA detection, we found that patients with HPV-DNA were younger (57.5 years vs. 70 years, p = 0.047), less likely to have phimosis (5.8% vs. 42.9%, p = 0.022) and more likely to have PeIN lesions than invasive SCC (85.7% vs. 27.8%, p = 0.025).

CONCLUSION

This study shows a prevalence of HPV-DNA in penile SCC and premalignant lesions of 45.5% and 92.9%, respectively. Identifying HPV involvement in SCC and PeIN pathology has the potential to guide treatment and enhance follow-up strategies.

Long-Term Periodic and Conditional Survival Trends in Prostate, Testicular, and Penile Cancers in the Nordic Countries, Marking Timing of Improvements

Survival studies are important tools for cancer control, but long-term survival data on high-quality cancer registries are lacking for all cancers, including prostate (PC), testicular (TC), and penile cancers. Using generalized additive models and data from the NORDCAN database, we analyzed 1- and 5-year relative survival for these cancers in Denmark (DK), Finland (FI), Norway (NO), and Sweden (SE) over a 50-year period (1971-2020). We additionally estimated conditional 5/1-year survival for patients who survived the 1st year after diagnosis. Survival improved early for TC, and 5-year survival reached 90% between 1985 (SE) and 2000 (FI). Towards the end of the follow-up, the TC patients who had survived the 1st year survived the next 4 years with comparable probability to the background population. For PC, the 90% landmark was reached between 2000 (FI) and after 2010 (DK). For penile cancer, 5-year survival never reached the 90% landmark, and the improvements in survival were modest at best. For TC, early mortality requires attention, whereas late mortality should be tackled for PC. For penile cancer, the relatively high early mortality may suggest delays in diagnosis and would require more public awareness and encouragement of patients to seek medical opinion. In FI, TC and penile cancer patients showed roughly double risk of dying compared to the other Nordic countries, which warrants further study and clinical attention.

Penile cancer in younger men-A more aggressive disease?

INTRODUCTION

Penile cancer (PC) in men under 45 is very rare with an incidence of 0.1 to 0.8/100,000. There is little published data on disease characteristics and outcomes of PC in younger men. Herein, we evaluate the disease characteristics and outcomes of penile cancer in younger men compared to an older cohort.

METHODS

This study included all men diagnosed with PC at our institution from 2016 to 2021. Primary outcomes included overall survival, cancer-specific survival, and disease-free survival. Secondary outcomes included disease characteristics and surgical management. Men aged ≤45 years (Group A) were compared with men aged >45 years (Group B) at diagnosis.

RESULTS

There were 90 patients treated for invasive PC over the study period. The median age at diagnosis was 64 (26-88). The mean length of follow-up was 27 (±18) months. There were 12 (13%) in Group A, and 78 (87%) patients in Group B. Group A had a worse cancer-specific survival compared to Group B (39 months vs. not reached, HR 0.1 (95%CI 0.02-0.85, P = 0.03). There was no significant difference in overall or disease-free survival between both groups. More men in Group A had lymph node metastases at the time of diagnosis (58% vs. 19%, P < 0.001). There was no significant difference in histopathological features including tumor subtype, grade, T stage, p53 status or presence of lymphovascular or perineural invasion.

CONCLUSION

In our study, younger men were more likely to have nodal involvement at time of diagnosis and had a worse cancer-specific survival.

Combination of Durvalumab and Chemotherapy to Potentially Convert Unresectable Stage IV Penile Squamous Cell Carcinoma to Resectable Disease: A Case Report

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

A comprehensive analysis of penile cancer in the region with the highest worldwide incidence reveals new insights into the disease

BACKGROUND

Although penile cancer (PC) is uncommon in developed countries, it is widespread in developing countries. The state of Maranhão (Northeast, Brazil) has the highest global incidence recorded for PC, and, despite its socioeconomic vulnerability, it has been attributed to human papillomavirus (HPV) infection. This study aimed to determine the histopathological features, the prevalence of HPV infection, and the immunohistochemical profile of PC in Maranhão.

METHODS

A retrospective cohort of 200 PC cases were evaluated. HPV detection was performed using nested-PCR followed by direct sequencing for genotyping. Immunohistochemistry (IHC) was performed using monoclonal antibodies anti-p16^INK4a, p53, and ki-67.

RESULTS

Our data revealed a delay of 17 months in diagnosis, a high rate of penile amputation (96.5%), and HPV infection (80.5%) in patients from Maranhão (Molecular detection). We demonstrated the high rate of HPV in PC also by histopathological and IHC analysis. Most patients presented koilocytosis (75.5%), which was associated with those reporting more than 10 different sexual partners during their lifetime (p = 0.001). IHC revealed frequent p16^INK4a overexpression (26.0%) associated with basaloid (p < 0.001) and high-grade tumors (p = 0.008). Interestingly, p16 appears not to be a better prognostic factor in our disease-free survival analysis, as previously reported. We also demonstrated high ki-67 and p53 expression in a subset of cases, which was related to worse prognostic factors such as high-grade tumors, angiolymphatic and perineural invasion, and lymph node metastasis. We found a significant impact of high ki-67 (p = 0.002, log-rank) and p53 (p = 0.032, log-rank) expression on decreasing patients' survival, as well as grade, pT, stage, pattern, and depth of invasion (p < 0.05, log-rank).

CONCLUSIONS

Our data reaffirmed the high incidence of HPV infection in PC cases from Maranhão and offer new insights into potential factors that may contribute to the high PC incidence in the region. We highlighted the possible association of HPV with worse clinical prognosis factors, differently from what was observed in other regions. Furthermore, our IHC analysis reinforces p16, ki-67, and p53 expression as important diagnosis and/or prognosis biomarkers, potentially used in the clinical setting in emerging countries such as Brazil.

Factors influencing symptom appraisal and help-seeking of older adults with possible cancer: a mixed-methods systematic review

BACKGROUND

The cancer burden falls predominantly on older (≥65 years) adults. Prompt presentation to primary care with cancer symptoms could result in earlier diagnosis. However, patient symptom appraisal and help-seeking decisions involving cancer symptoms are complex and may be further complicated in older adults.

AIM

To explore the effect of older age on patients' appraisal of possible cancer symptoms and their decision to seek help for these symptoms.

DESIGN AND SETTING

Mixed-methods systematic review.

METHOD

MEDLINE, EMBASE, CINAHL, PsycINFO, Cochrane Library, Web of Science Core Collection, ASSIA, the ISRCTN registry, and the National Institute for Health and Care Excellence were searched for studies on symptom appraisal and help-seeking decisions for cancer symptoms by adults aged ≥65 years. Studies were analysed using thematic synthesis and according to the Synthesis Without Meta-Analysis guidelines.

RESULTS

Eighty studies were included with a total of 32 995 participants. Studies suggested a possible association between increasing age and prolonged symptom appraisal interval. Reduced knowledge of cancer symptoms and differences in symptom interpretation may contribute to this prolonged interval. In contrast, in the current study a possible association was found between increasing age and prompt help-seeking. Themes affecting help-seeking in older adults included the influence of family and carers, competing priorities, fear, embarrassment, fatalism, comorbidities, a desire to avoid doctors, a perceived need to not waste doctors' time, and patient self-management of symptoms.

CONCLUSION

This review suggests that increasing age is associated with delayed cancer symptom appraisal. When symptoms are recognised as potentially serious, increasing age was associated with prompt help-seeking although other factors could prolong this. Policymakers, charities, and GPs should aim to ensure older adults are able to recognise potential symptoms of cancer and seek help promptly.

Use of flaps in inguinal lymphadenectomy in metastatic penile cancer

PURPOSE

Reviewing surgical procedures using fasciocutaneous and myocutaneous flaps for inguinal reconstruction after lymphadenectomy in metastatic penile cancer.

MATERIAL AND METHODS

We reviewed the current literature of the Pubmed database according to PRISMA guidelines. The search terms used were "advanced penile cancer", "groin reconstruction", and "inguinal reconstruction", both alone and in combination. The bibliographic references used in the selected articles were also analyzed to include recent articles into our research.

RESULTS

A total of 54 studies were included in this review. About one third of penile cancers are diagnosed with locally advanced disease, often presenting with large lymph node involvement. Defects in the inguinal region resulting from the treatment of metastatic penile cancer are challenging for the surgeon and cause high patient morbidity, rendering primary closure unfeasible. Several fasciocutaneous and myocutaneous flaps of the abdomen and thigh can be used for the reconstruction of the inguinal region, transferring tissue to the affected area, and enabling tensionless closure.

CONCLUSIONS

The reconstruction of defects in the inguinal region with the aid of flaps allows for faster postoperative recovery and reduces the risk of complications. Thus, the patient will be able to undergo potential necessary adjuvant treatments sooner.

Recent Advances in the Management of Penile Cancer: A Contemporary Review of the Literature

Penile cancer is a rare condition, which mostly affects men in their sixth decade of life. The most common histology is squamous cell carcinoma (SCC), with about half of the cases linked to human papilloma virus (HPV) infection. The lack of awareness and significant social and psychological stigma associated with penile cancer often leads to delays in presentation, diagnosis and management. Timely multidisciplinary care at experienced centers is therefore critical for improving outcomes. For patients with advanced disease, treatment options are limited and prognosis remains poor. Large international efforts are underway to further define the optimal standards of care. Targeted therapies and immune checkpoint inhibitors could potentially play a role in advanced disease and are under evaluation in clinical trials. In this review, we discuss the current management of penile cancer and future directions.

Underutilization of Surgical Standard of Care for Insured Men with Invasive Penile Cancer

PURPOSE

Prior studies of mixed insurance populations have demonstrated poor adherence to surgical standard of care (SOC) for penile cancer. We used data from the Surveillance, Epidemiology and End Results (SEER) cancer registry linked to Medicare to calculate SOC adherence to surgical treatment of penile cancer in insured men over the age of 65, focusing on potential social and racial disparities.

METHODS

This is an observational analysis of patients with T2-4 penile cancer of any histologic subtype without metastasis in the SEER-Medicare database (2004-2015). SOC was defined as penectomy (partial or radical) with bilateral inguinal lymph node dissection (ILND) based on the National Comprehensive Cancer Network guidelines. We calculated proportions of those receiving SOC and constructed multivariate models to identify factors associated with receiving SOC.

RESULTS

A total of 447 men were included. Of these men, 22.1% (99/447) received SOC while 18.8% (84/447) received no treatment at all. Only 23.3% (104/447) had ILND while 80.9% (362/447) underwent total or partial penectomy. Race and socioeconomic status (SES) were not associated with decreased SOC. Increasing age (OR 0.93, 95%CI:0.89-0.96), Charlson Comorbidity Index score ≥ 2 (OR 0.53, 95%CI:0.29-0.97), and T3-T4 disease (OR 0.34, 95%CI:0.18-0.65) were associated with not receiving SOC on adjusted analysis.

CONCLUSIONS

Rates of SOC are low among insured men 65 years of age or older with invasive penile cancer, regardless of race or SES. This finding is largely driven by low rates of ILND. Strategies are needed to overcome barriers to SOC treatment for men with invasive penile cancer.

A Clinical Nomogram for Predicting Lymph Node Metastasis in Penile Cancer: A SEER-Based Study

Purpose: We developed a nomogram to predict the possibility of lymph node metastasis in patients with squamous cell carcinoma of the penis.

Methods: Identifying patients with squamous cell carcinoma of the penis diagnosed between 2004 and 2015 in the Surveillance, Epidemiology, and End Results (SEER) database. Univariate and multivariate analyses were carried out by logistic regression to assess significant predictors associated with lymph node metastasis. A nomogram was established and validated by a calibration plot and receptor operating characteristic curve (ROC) analysis.

Results: A total of 1,016 patients with penile squamous cell carcinoma (SCCP) were enrolled in this study. One hundred and ninety-five patients (19%) had lymph node involvement (N1-3). Multivariate analysis showed that age, primary tumor site, grade, tumor size, and T stage were identified as being significantly (p < 0.05) associated with lymph node involvement. All the above factors that showed a statistically significant predictive capability were selected for building the nomogram. This model had a calibration slope of 0.9 and a c-index of 0.776, indicating the good discrimination and effectiveness of the nomogram in predicting lymph node status.

Conclusion: Although the prediction model has some limitations, the nomogram revealed the relationship between the clinicopathological characteristics of SCCP patients and the risk of lymph node metastasis. This tool will assist patients in counseling and guide treatment decisions for SCCP patients.

An overview of the diagnoses and treatments for penile cancer

Penile cancer is a rare malignancy and, as a consequence, it is managed in just a few specialist centres across the UK. This article aims to provide health professionals with an introduction and update on the epidemiology and aetiology of penile cancer, as well as the techniques used to diagnose penile cancer and the current treatment options. The article highlgihts the importance of early diagnosis and the role that the clinical nurse specialist in plays supporting those diagnosed with the penile cancer and their families.

Penile cancer: a Brazilian consensus statement for low- and middle-income countries

PURPOSE

Penile cancer is highly prevalent in low- and middle-income countries, with significant morbidity and mortality rates. The first Brazilian consensus provides support to improve penile cancer patients' outcomes, based on expert's opinion and evidence from medical literature.

METHODS

Fifty-one Brazilian experts (clinical oncologists, radiation oncologists, urologists, and pathologists) assembled and voted 104 multiple-choice questions, confronted the results with the literature, and ranked the levels of evidence.

RESULTS

Healthcare professionals need to deliver more effective communication about the risk factors for penile cancer. Staging and follow-up of patients include physical examination, computed tomography, and magnetic resonance imaging. Close monitoring is crucial, because most recurrences occur in the first 2-5 years. Lymph-node involvement is the most important predictive factor for survival, and management depends on the location (inguinal or pelvic) and the number of lymph nodes involved. Conservative treatment may be helpful in selected patients without compromising oncological outcomes; however, surgery yields the lowest rate of local recurrence.

CONCLUSION

This consensus provides an essential decision-making orientation regarding this challenging disease.

Inguinal lymph node dissection for penile cancer: a contemporary review

Penile cancer is an uncommon disease associated with significant psychological and physical morbidity. Penile cancer has an expectable pattern of spread in a stepwise fashion, from inguinal to pelvic lymph nodes (PLN) then distant spread. Patients with penile cancer have variable survival, with patients with a low burden of nodal metastatic disease having lasting survival with surgical management, however patients with a large amount of locoregional metastatic disease having a worse prognosis. The current management options for patients with metastatic lymph node disease in penile cancer aims to reduce the morbidity associated with radical inguinal lymph node (ILN) surgery with appropriate risk stratification to optimise oncological control of the disease. This article describes current challenges in managing the inguinal region in patients with penile squamous cell carcinoma (SCC).

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.

Penile cancer trends and economic burden in the Brazilian public health system

Objective:

To gather information on penile cancer epidemiologic trends and its economic impact on the Brazilian Public Health System across the last 25 years.

Methods:

The Brazilian Public Health System database was used as the primary source of data from January 1992 to December 2017. Mortality and incidence data from the Instituto Nacional de Câncer José Alencar Gomes da Silva was collected using the International Classification of Diseases ICD10 C60. Demographic data from the Brazilian population was obtained from the last census by the Brazilian Institute of Geography and Statistics, performed in 2010 and its 2017 review.

Results:

There were 9,743 hospital admissions related to penile cancer from 1992 to 2017. There was a reduction (36%) in the absolute number of admissions per year related to penile cancer in 2017, as compared to 1992 (2.7versus 1.7 per 100,000; p<0.001). The expenses with admissions related to this condition in this period were US$ 3,002,705.73 (US$ 115,488.68/year). Approximately 38% of the total amount was spent in Northeast Region. In 1992, penile cancer costed US$ 193,502.05 to the public health system, while in 2017, it reduced to US$ 47,078.66 (p<0.02). Penile cancer incidence in 2017 was 0.43/100,000 male Brazilian, with the highest incidence rate found in the Northeast Region. From 1992 to 2017, the mortality rates of penile cancer in Brazil were 0.38/100,000 man, and 0.50/100,000 man in the North Region.

Conclusion:

Despite the decrease in admissions, penile cancer still imposes a significant economic and social burden to the Brazilian population and the Public Health System.

Rare male cancers: Effect of social deprivation on a cohort of penile cancer patients

Background:

Penile cancer is a rare disease, with approximately 600 cases diagnosed every year in the UK. In this study, we assessed the impact of social deprivation on penile cancer, concentrating on incidence, disease factors, surgical treatment and mortality within our ‘Supranetwork’ population.

Methods:

All cases of penile cancer in the West of Scotland were identified from the uro-oncology multidisciplinary team meetings over a 10-year period covering January 2008 to December 2017. Patients underwent treatment within the remit of a centralised service, and social deprivation was determined using the Scottish Index of Multiple Deprivation (SIMD), which is the Scottish government’s official tool to identify areas of multiple deprivations.

Results:

A total of 278 patients were identified, with an age range of 27–97 years ( M=64 years). The incidence of penile cancer in SIMD category 1 (most deprived) is 7.2/100,000 population at risk compared to 2.8/100,000 population at risk in SIMD category 5 (least deprived). Histologically, a higher proportion of aggressive grade 3 cancers (45% vs. 16%, p=0.03) and more advanced N2/N3 nodal disease (63% vs. 33%, p=0.04) was found in SIMD category 1 compared to SIMD category 5, suggesting higher incidence of delayed presentation with more advanced and aggressive disease in the most deprived populations.

Conclusions:

The level of social deprivation shows a significant association with penile cancer incidence, tumour grade and stage at time of diagnosis, with a resulting disproportionate impact on morbidity and mortality in the most deprived cohort of patients. Public awareness and efforts to increase earlier diagnoses of penile cancer in these ‘hard to reach’ men should be an important step in improving overall outcomes from penile cancer.

Risk factors for the delay in the diagnosis of penile lesions: results from a single center in Italy

BACKGROUND

Early diagnosis is fundamental for the investigation and treatment of penile lesions. There is an unfortunate documented delayed in presentation and diagnosis of penile lesions. Literature is scant regarding the risk factors contributing to this delay in a Mediterranean population. Few previous reports are published in entirely different homogeneous populations. The objective of this study was to provide an analysis of the causes and risk factors related to the delay of the first medical visit in a North Italian population subgroup.

METHODS

From September 2004 to September 2017, 184 consecutive patients were treated at our institute with a surgical approach for a penile lesion. The epidemiological factors and reasons for the delay to diagnosis were recorded during personal or telephonic interviews. Univariate logistic regression models were performed to screen for an effect of the clinical and demographic variables on the delay in diagnosis. Variables with a P value <0.05 were entered into multivariate analysis, where the delay in diagnosis was the dependent variable.

RESULTS

One hundred and thirteen patients were enrolled. The average patient age was fifty-eight. The average delay between the appearance of the lesion and the first medical consultation was fifty-three days. The principal cause of delay was the lack of knowledge of penile lesions and secondly, the feeling of embarrassment of having to visit a doctor. The multivariate analysis reported a significant correlation between the level of education, sexual activity and extramarital affairs on the delay in presentation (P values respectively: 0.01, 0.009 and 0.04).

CONCLUSIONS

Patients education regarding this pathology and its potential danger is inadequate and thus it is necessary to implement a campaign of information and prevention in order to reduce delayed diagnosis.

Demographic and socioeconomic predictors of treatment delays, pathologic stage, and survival among patients with penile cancer: A report from the National Cancer Database

OBJECTIVES

To evaluate whether socioeconomic factors affect pathologic stage, treatment delays, pathologic upstaging, and overall survival (OS) in patients with penile cancer (PC).

PATIENTS AND METHODS

A total of 13,283 eligible patients diagnosed with PC from 1998 to 2012 were identified from the National Cancer Database. Socioeconomic, demographic and pathologic variables were used in multivariable regression models to identify predictors of pathologic T stage ≥2, pathologic lymph node positivity, cT to pT upstaging, treatment delays, and OS.

RESULTS

A 5-year OS was 61.5% with a median follow-up of 41.7 months. Pathologic T stage ≥2 was identified in 3,521 patients (27.2%), 1,173 (9.2%) had ≥pN1 and 388 (7.9%) experienced cT to pT upstaging. Variables associated with a higher likelihood of pathologic T stage ≥2 included no insurance (OR = 1.79, P<0.001), lower higher education based on zip code (OR = 1.13, P = 0.027), black race (OR = 1.17, P = 0.046) and Hispanic ethnicity (OR = 1.66, P<0.001). Patients with Hispanic ethnicity (OR = 1.46; P<0.001) or living in nonmetropolitan areas were more likely to have ≥pN1 (P = 0.001). Lack of insurance was associated with cT to pT upstaging (OR = 2.05, P = 0.001) as was living in an urban vs. metropolitan area (OR = 1.35, P = 0.031). In addition to TNM stage, black vs. white race (HR = 1.56, P<0.001), living in an urban vs. metropolitan area (hazard ratio [HR] = 1.18, P = 0.022), age (HR = 1.04, P<0.001) and Charlson score (HR = 1.49, P<0.001) were associated with lower OS.

CONCLUSION

Socioeconomic variables including no insurance, lower education, race, Hispanic ethnicity, and nonmetropolitan residence were found to be poor prognostic factors. Increased educational awareness of this rare disease may help reduce delays in diagnosis, improve prognosis and ultimately prevent deaths among socioeconomically disadvantaged men with PC.

How do men’s magazines talk about penises?

Constructions of masculinity have shifted and changed but the central role of the penis has remained firm. Yet, despite the implications for sexual health, there has been very little research on discourses around penises. The messages men receive about their manhood is apparent in articles in men’s magazines. We conducted a discursive analysis of the ways in which penises were discussed in four market leading UK titles: Loaded, Men’s Health, GQ and Attitude. Two broad discourses were identified, termed Laddish and Medicalised, both of which create fear-ridden spaces where men are bombarded with unachievable masculine ideals and traumatic examples of mutilated members. We discuss how health psychologists could use the findings to communicate with men about their sexual health needs using this channel.

Updates on the epidemiology and risk factors for penile cancer

Penile cancer is a rare neoplasm representing less than 1% of all malignancies in the USA and Europe but is a significant public health hazard in the developing world. Male neonatal circumcision has been associated with a dramatic decrease in penile cancer rates with countries such as Israel, where circumcision is widely performed, having the lowest incidence in the world at <0.1% of malignancies. Many risk factors have been identified for penile cancer including phimosis, lack of circumcision, obesity, lichen sclerosis, chronic inflammation, smoking, UVA phototherapy, socioeconomic status, human papillomavirus (HPV) infection and immune compromised states. The relationship between these factors and invasive disease varies and continues to be investigated. Our objective was to present a contemporary overview of the epidemiology and risk factors for invasive penile cancer.

Measures of psychosocial factors that may influence help-seeking behaviour in cancer: A systematic review of psychometric properties

Advanced stage cancer is frequently attributed to delays in presentation to a healthcare professional. To reduce undue delay, it is imperative to understand the reasons underlying help-seeking behaviour and to measure those using valid and reliable tools. This systematic review aimed to identify how studies have measured psychosocial factors affecting time to presentation for (potential) cancer symptoms. A total of 35 studies were included. Most studies failed to use valid and reliable tools, and predominantly provided inconclusive results regarding psychosocial factors and time to presentation when no or minimal psychometric evidence was present. Consequently, measure selection and future measure development should be guided by psychometric principles.

Clinicopathologic Characteristics and Treatment Outcomes of Penile Cancer

Purpose

The aim of this study was to assess the clinicopathologic characteristics of penile cancer, including patterns of therapy, oncologic results, and survival.

Materials and Methods

Between January 2005 and July 2015, 71 patients at 6 institutions who had undergone penectomy or penile biopsy were enrolled. Their medical records were reviewed to identify the mode of therapy, pathology reports, and cancer-specific survival (CSS) rate.

Results

Clinicopathologic and outcome information was available for 52 male patients (mean age, 64.3 years; mean follow-up, 61.4 months). At presentation, 17 patients were node-positive, and 4 had metastatic disease. Management was partial penectomy in 34 patients, total penectomy in 12 patients, and chemotherapy or radiotherapy in 6 patients. The pathology reports were squamous cell carcinoma in 50 patients and other types of carcinoma in the remaining 2 patients. Kaplan-Meier survival analysis showed a 5-year CSS rate of 84.0%. In univariate and multivariate analyses, the American Joint Committee on Cancer (AJCC) stage and pathologic grade were associated with survival.

Conclusions

Partial penectomy was the most common treatment of penile lesions. The oncologic outcomes were good, with a 5-year CSS of 84.0%. The AJCC stage and pathologic grade were independent prognostic factors for survival.

Socioeconomic factors and penile cancer risk and mortality; a population-based study

OBJECTIVE

To investigate possible associations between socioeconomic status (SES) and penile cancer risk, stage at diagnosis, and mortality.

PATIENTS/SUBJECTS AND METHODS

A population-based register study including men in Sweden diagnosed with penile cancer between 2000 and 2012 (1676 men) and randomly chosen controls (9872 men). Data were retrieved from the National Penile Cancer Register (NPECR) and several other population-based healthcare and sociodemographic registers. Educational level, disposable income, marital status, and number of individuals in the household, were assessed as indicators of SES. The risk of penile cancer and penile cancer death in relation to SES were estimated using logistic regression and proportional hazards models, respectively. Cumulative cause-specific mortality (CSM) estimates by SES were calculated using the Kaplan-Meier method.

RESULTS

A low educational level and low disposable income were associated with an increased risk of invasive penile cancer. Furthermore, low educational level was associated with more advanced primary tumour stage. Divorced and never married men had a generally increased risk of penile cancer and were diagnosed with more advanced primary tumour stages. However, neither educational level nor marital status was associated with lymph node or distant metastases. Also, men in single-person households had an increased risk of both non-invasive and invasive disease. In men with invasive penile cancer, there were no significant associations of indicators of SES and CSM.

CONCLUSIONS

Low educational level, low disposable income, being divorced or never married, and living in a single-person household, all increase the risk of advanced stage penile cancer, but not lymph node or distant metastases. The assessed indicators of SES did not influence penile CSM. In conclusion, our findings indicates that SES influences the risk and stage of penile cancer, but not survival.

Risk factors and negative consequences of patient's delay for penile carcinoma

BACKGROUND

Delayed first medical consultation (patient's delay) is quite common in cases of penile carcinoma (PC), but its reasons and impacts remain unclear. We conducted this study to ascertain risk factors resulting in delayed treatment seeking and evaluate its influence on prognosis.

METHODS

From 2004 to 2010 at 4 centers, 254 patients were enrolled into this study from 262 consecutive PC cases. Patients' sexual performance was investigated using the International Index of Erectile Function (IIEF)-15 at the sixth-month end after treatment. Data for prognostic analyses was obtained via a 5-year follow-up.

RESULTS

A multivariate model ascertained 4 risk factors (single, living in rural areas, heavy drinking alcohol, and aspecific initial symptoms) and 1 protective factor (history of condyloma) significantly associated with patient's delay. Delay >3 months led to significant risks for adverse clinical characteristics, low penis-sparing rate, and poor sexual function restoration. Although patient's delay was not found to impact on postoperative relapses and 5-year overall survival (OS), patients with delay >6 months had significantly inferior 2-year OS.

CONCLUSIONS

Single, living in rural areas, heavy drinking alcohol, and aspecific initial symptoms are significant risk factors of PC associated with patient's delay. Delay >3 months will lead to significantly inferior clinical consequences. Minimizing patient's delay is the key to avoid amputation and retain superior sexual potency. Improving patient education on initial symptoms of PC is necessary in men of >40 years old.

DaPeCa-2: Implementation of fast-track clinical pathways for penile cancer shortens waiting time and accelerates the diagnostic process--A comparative before-and-after study in a tertiary referral centre in Denmark

OBJECTIVE

The aim of this study was to examine the feasibility and impact of a fast-track referral pathway on clinical time intervals in penile cancer.

MATERIALS AND METHODS

This observational study from a tertiary referral centre included 263 patients diagnosed before and after the introduction of an intervention to reduce clinical time intervals, the Cancer Patient Pathway (CPP). The CPP included fast-track referral and set time-frames for units participating in cancer diagnosis and treatment, and was introduced for penile cancer in Denmark on 1 January 2009. Median time intervals (in calendar days) with interquartile range were the main outcome measure.

RESULTS

A trend towards reduction was observed in all clinical time intervals, with a statistically significant reduction in the system interval (p = 0.01) and tertiary centre interval (p < 0.0001). The proportion of patients treated within the maximum accepted time-frame of 37 days after referral steadily increased after implementation of the CPP. In particular, unjustified waiting time was reduced significantly. This was mainly achieved through pre-booking of appointments and diagnostic time slots by a dedicated clinical coordinator.

CONCLUSIONS

To the authors' knowledge, this is the first study examining the feasibility and impact of an intervention to reduce clinical time intervals in penile cancer. The Danish CPP was successful in reducing system and tertiary centre intervals. Future interventions need to address the long patient interval. Longer follow-up is needed to study the impact of CPP on mortality.

Psychosocial factors that influence men's help-seeking for cancer symptoms: a systematic synthesis of mixed methods research

OBJECTIVE

Effectiveness of cancer control partly depends upon early identification and treatment. Men appear to be more likely to delay help-seeking for symptoms, resulting in later diagnosis. This review aims to provide a mixed research synthesis of the psychosocial barriers to and facilitators of help-seeking for cancer symptoms among men.

METHODS

Systematic methods were followed, including a predefined research question and search strategy. Searches retrieved 7131 international records from online databases: MEDLINE (n = 3011), PubMed (n = 471), SCOPUS (n = 896), Informit (n = 131), PsychINFO (n = 347), and Web of Science (n = 2275). Forty studies were eligible for inclusion in the review (25 qualitative studies, 11 quantitative studies, and 4 mixed-method studies).

RESULTS

There was strong observational evidence for several psychosocial barriers to men's help-seeking behaviour: low cancer knowledge and inaccurate symptom interpretation, embarrassment and fear, and conformity to masculine gender role norms. The strongest facilitating factor associated with men's help-seeking behaviour was encouragement and support of spouses and family members. The majority of research was qualitative and used small samples, making generalisations to the wider population difficult.

CONCLUSIONS

Men's help-seeking for cancer symptoms is influenced by several psychosocial factors, which, in part, may be gender-specific. Health promotion initiatives to improve help-seeking behaviour among men should aim to increase cancer knowledge, reduce embarrassment and fear, address social norms deterring timely help-seeking, and acknowledge informal help-seeking with spouses and family members. Increasing the theoretical grounding of research could aid cohesion across the research area and the design of effective health promotion interventions. Copyright © 2015 John Wiley & Sons, Ltd.

Dyadic Aspects of Sexual Well-Being in Men with Laser-Treated Penile Carcinoma

INTRODUCTION

Coping with cancer, its treatment and recovery are dyadic processes within a relationship. Sexual dysfunctions and problems of penile cancer may add to the demands of coping.

AIM

The prospective study aimed to describe the dyadic aspects of sexual well-being and life satisfaction before and 1 year after organ-sparing laser treatment of penile carcinoma.

METHODS

A consecutive series of 29 patients with penile carcinoma suitable for laser treatment were included together with their partners, median age 60 (37-73) years and 57 (30-72) years, respectively. Median length of relationship was 29 years (1-54 years). The participants completed structured interviews before treatment, at 6 months' and 12 months' follow-up. The interview addressed sexual activities, sexual functions, verbal (sexual) communication, and life satisfaction.

MAIN OUTCOME MEASURES

Three well-validated instruments were included: Hospital Anxiety and Depression Scale, International Index of Erectile Function-5, and Life Satisfaction checklist, LiSat-11. The interviews contained the same questions for patients and partners at all three measuring points.

RESULTS

There was a high level of within-couple agreement on sexual activities, sexual function, and life satisfaction before and after organ-sparring treatment. No significant differences between interview data at 6 and 12 months' follow-up occurred. Before treatment, sexual dysfunctions were common among men, especially decreased sexual interest and dyspareunia. At follow-up, increased sexual function was found, with the exception of erectile function and women's orgasm. A rather high proportion was being unsatisfactory sexually inactive. Few had an ongoing verbal (sexual) mutual communication. Couples with an active sexual life at follow-up showed coherence in high satisfaction with life as a whole.

CONCLUSION

A high level of within-couple agreement concerning sexuality and life satisfaction points to the necessity of including an adequate sexological case history, counseling, and treatment for this group of patients and their partners.

The role of emotions in time to presentation for symptoms suggestive of cancer: a systematic literature review of quantitative studies

BACKGROUND

Emotions may be important in patients' decisions to seek medical help for symptoms suggestive of cancer.

OBJECTIVES

The aim of this systematic literature review was to examine quantitative literature on the influence of emotion on patients' help-seeking for symptoms suggestive of cancer. The objectives were to identify the following: (a) which types of emotions influence help-seeking behaviour, (b) whether these form a barrier or trigger for seeking medical help and (c) how the role of emotions varies between different cancers and populations.

METHODS

We searched four electronic databases and conducted a narrative synthesis. Inclusion criteria were studies that reported primary, quantitative research that examined any emotion specific to symptom appraisal or help-seeking for symptoms suggestive of cancer.

RESULTS

Thirty-three papers were included. The studies were heterogeneous in their methods and quality, and very few had emotion as the main focus of the research. Studies reported a limited range of emotions, mainly related to fear and worry. The impact of emotions appears mixed, sometimes acting as a barrier to consultation whilst at other times being a trigger or being unrelated to time to presentation. It is plausible that different emotions play different roles at different times prior to presentation.

CONCLUSIONS

This systematic review provides some quantitative evidence for the role of emotions in help-seeking behaviour. However, it also highlighted widespread methodological, definition and design issues among the existing literature. The conflicting results around the role of emotions on time to presentation may be due to the lack of definition of each specific emotion.
