RESUMO

OBJECTIVE: Identification of superficial inguinal lymph nodes during low-risk penile cancer surgery using near-infrared (NIR) fluorescence to improve the accuracy of lymph-node dissection and reduce the incidence of missed micrometastases and complications. METHODS: Thirty-two cases were selected, which were under the criteria of < T1, and no lymph-node metastasis was found with magnetic resonance imaging (MRI) detection. Two groups were randomly divided based on the fluorescence technique, the indocyanine green (ICG) group and the non-ICG group. In the ICG group, the ICG preparation was subcutaneously injected into the edge of the penile tumor 10 min before surgery, and the near-infrared fluorescence imager was used for observation. After the lymph nodes were visualized, the superficial inguinal lymph nodes were removed first, and then, the penis surgery was performed. The non-ICG group underwent superficial inguinal lymph-node dissection and penile surgery. RESULTS: Among the 16 patients in the ICG group, we obtained 11 lymph-node specimens using grayscale values of images (4.13 ± 0.72 vs. 3.00 ± 0.82 P = 0.003) along with shorter postoperative healing time (7.31 ± 1.08 vs. 8.88 ± 2.43 P = 0.025), and less lymphatic leakage (0 vs. 5 P = 0.04) than the 16 patients in the non-ICG group. Out of 11, 3 lymph nodes that are excised were further grouped into fluorescent and non-fluorescent regions (G1/G2) and found to be metastasized. CONCLUSION: Near-infrared fluorescence-assisted superficial inguinal lymph-node dissection in penile carcinoma is accurate and effective, and could reduce surgical complications.

RESUMO

BACKGROUND: Fasciitis ossificans is a rare subtype of nodular fasciitis, a benign soft tissue tumor with reactive characteristics. Due to its rapid growth, it is often misdiagnosed as a malignant tumor. While fasciitis ossificans commonly originates from the subcutaneous tissue and can appear throughout the body, it may also arise from extraordinary sites. CASE PRESENTATION: We report the first-ever documented case of fasciitis ossificans arising from the penis in a male patient who presented with a tumor on the glans penis. The tumor was surgically resected due to suspicion of penile cancer. Initial histopathological analysis led to a misdiagnosis of squamous cell carcinoma. However, pathological consultation ultimately confirmed the diagnosis of fasciitis ossificans of the penis originating from the glans penis by demonstrating ossification. CONCLUSION: This case underscores the importance of considering fasciitis ossificans in the differential diagnosis of soft tissue tumors, even in unusual locations such as penile soft tissue.

RESUMO

BACKGROUND: Penile squamous cell carcinoma (PSCC) is a rare malignancy that may be cured in cases of local disease by resection of the primary tumor. Risk factors and patterns of local recurrence (LR) have not been well described in cases requiring partial or radical penectomy. In this study, we evaluated risk factors for LR and the impact of frozen and final margin assessment. MATERIALS AND METHODS: We evaluated 119 patients with PSCC who had undergone partial or radical penectomy from 2007 to 2023. Data regarding clinical and pathologic features were collected by retrospective chart review. The primary outcome of interest was LR. Determinants of LR were analyzed by Student's t, Fisher's exact, chi-square and logistic regression analysis. Predictive statistics of frozen margin status on final margin were assessed and LR rates for subsets of frozen and final margin interaction were defined. Finally, all cases of positive margins and LR were described to highlight patterns of LR and the importance of margin status in these cases. RESULTS: There were 8 (6.7%) cases of local recurrence. There were no significant predictors of LR, although a trend toward increased LR risk was observed among those with a positive final margin. Positive final margins were found in 15 (13%) cases. Frozen margin analysis was utilized in 79 cases, of which 10 (13%) were positive. The sensitivity, specificity, positive predictive value, and negative predictive value of frozen margin status for final margins were 44%, 92%, 40%, and 93%, respectively. There were no LR among cases in which frozen margin was not sent. Analysis of all cases with positive margin and/or LR identified three subsets of patients: CIS or focally positive margin resulting in either no LR or LR managed with minimal local intervention, bulky disease in which survival is determined by response to subsequent therapy rather than local recurrence, and clinically significant local recurrence requiring continued surveillance and intervention despite negative margins. CONCLUSIONS: LR is rare, even in cases of larger, proximal tumors requiring partial or radical penectomy. In this study, no statistically significant risk factors for local recurrence were identified; however, analysis of frozen and final margins provided insight into the importance of margin status and patterns of local recurrence. When feasible, visibly intra-operative negative margins are an excellent predictor of low risk for LR, and, in cases of CIS or focally positive margins, further resection to achieve negative margins is unlikely to reduce the risk of clinically significant LR. Additionally, in cases of bulky disease, the goals of resection should be focused toward palliation and next line therapy.

RESUMO

Background and Objectives: To investigate the role of preoperative albumin-to-alkaline phosphatase ratio (AAPR) in predicting pathologic node-positive (pN+) disease in penile cancer (PC) patients undergoing inguinal lymph node dissection (ILND). Materials and Methods: Clinical data of patients with squamous cell carcinoma (SCC) PC + ILND at a single high-volume institution between 2016 and 2021 were collected and retrospectively analyzed. An AAPR was obtained from preoperative blood analyses performed within 30 days from their scheduled surgery. A ROC curve analysis was used to assess AAPR cutoff, in addition to the Youden Index. Logistic regression analysis was utilized for an odds ratio (OR), 95% confidence interval (CI) calculations, and an estimate of pN+ disease. A p value < 0.05 was considered to be as statistically significant. Results: Overall, 42 PC patients were included in the study, with a mean age of 63.6 ± 12.9 years. The AAPR cut-off point value was determined to be 0.53. The ROC curve analysis reported an AUC of 0.698. On multivariable logistic regression analysis lymphovascular invasion (OR = 5.38; 95% CI: 1.47-9.93, p = 0.022), clinical node-positive disease (OR = 13.68; 95% CI: 4.37-43.90, p < 0.009), and albumin-to-alkaline phosphatase ratio ≤ 0.53 (OR = 3.61; 95% CI: 1.23-12.71, p = 0.032) were predictors of pN+ involvement. Conclusions: Preoperative AAPR may be a potentially valuable prognostic marker of pN+ disease in patients who underwent surgery for PC.

RESUMO

Objective: Small series and individual cases of penile soft tissue tumours are reported in the literature: these are rare tumours that represent less than 5% of all penile tumours. Methods: Penile soft tissue tumours were collected from the archive of the Department of Pathology at the Istituto Nazionale dei Tumori of Milan between January 1990 and October 2021. All available medical records were retrieved and reviewed to obtain clinical information. Results: Our series refers to the 30-year experience of highlighting the heterogeneity in the presentation and microscopic features of these rare sarcomas. 18 penile soft tissue tumours are described, 4 benign and 14 malignant. The mean age at diagnosis was 58.2 years (range 24-96 years) and 53.6 years among malignancies (range 24-89). The most frequent histotype was Kaposi's sarcoma (nr = 4) and very unusual histotypes were observed, namely low-grade fibromyxoid sarcoma, synovial sarcoma, proximal type epithelioid sarcoma and the first reported case of dedifferentiated liposarcoma of the penis. Conclusions: Among sarcomas of the genitourinary tract, tumours of the soft tissues of the penis are the rarest. Penile sarcomas can present at a young age. Kaposi's sarcoma in HIV-negative patients has a favorable outcome, while deep sarcomas have an aggressive behavior and poor prognosis.

RESUMO

OBJECTIVE: To evaluate perioperative and oncologic outcomes of a cohort of clinically node negative high-risk penile cancer patients undergoing robotic assisted inguinal lymph node dissection (RAIL) compared to patients undergoing open superficial inguinal lymph node dissection (OSILND). PATIENTS AND METHODS: We retrospectively reviewed the clinical characteristics and outcomes of clinically node negative high-risk penile cancer patients undergoing RAIL at MDACC from 2013-2019. We sought to compare this to a contemporary open cohort of clinically node negative patients treated from 1999 to 2019 at MDACC and Moffit Cancer Center (MCC) with an OSILND. Descriptive statistics were used to characterize the study cohorts. Comparison analysis between operative variables was performed using Fisher's exact test and Wilcoxon's rank-sum test. The Kaplan-Meier method was used to estimate survival endpoints. RESULTS: There were 24 patients in the RAIL cohort, and 35 in the OSILND cohort. Among the surgical variables, operative time (348.5 minutes vs. 239.0 minutes, P < 0.01) and the duration of operative drain (37 vs. 22 days P = 0.017) were both significantly longer in the RAIL cohort. Complication incidences were similar for both cohorts (34.3% for OSILND vs. 33.3% for RAIL), with wound complications making up 33% of all complications for RAIL and 31% of complications for OSILND. No inguinal recurrences were noted in either cohort. The median follow-up was 40 months for RAIL and 33 months for OSILND. CONCLUSIONS: We observed similar complication rates and surgical variable outcomes in our analysis apart from operative time and operative drain duration. Oncological outcomes were similar between the two cohorts. RAIL was a reliable staging and potentially therapeutic procedure among clinically node negative patients with penile squamous cell carcinoma with comparable outcomes to an OSILND cohort.

RESUMO

BACKGROUND: Radical inguinal lymph node dissection (rILND) is the most available treatment to cure penile cancer (PC) with limited inguinal-confined disease. However, guidelines regarding acceptable boundaries of rILND are controversial, and consensus is lacking. The authors aimed to standardize the surgical boundaries of rILND with definite pathological evidence and explore the distribution pattern of inguinal lymph nodes (ILNs) in PC. METHODS: A total of 414 PC patients from two centers who underwent rILND were enrolled. The ILN distribution was divided into seven zones anatomically for pathological examination. Student's t test and Kaplan-Meier survival analysis were used. RESULTS: ILNs displayed a funnel-shaped distribution with high density in superior regions. ILNs and metastatic nodes are present anywhere within the radical boundaries. Positive ILNs were mainly concentrated in zone I (51.7%) and zone II (41.3%), but there were 8.7% and 12.3% in inferior zones V and VI, respectively, and 7.1% in the deep ILNs. More importantly, a single positive ILN and first-station positive zone was detected in all seven regions. Single positive ILNs were located in zones I through VI in 40.4%, 23.6%, 6.7%, 18.0%, 4.5%, and 1.1%, respectively, and 5.6% presented deep ILN metastasis directly. CONCLUSIONS: The authors established a detailed ILN distribution map and displayed lymphatic drainage patterns with definite pathological evidence using a large cohort of PC patients. Single positive ILNs and first-station metastatic zones were observed in any region, even directly with deep ILN metastasis. Only rILND can ensure tumor-free resection without the omission of positive nodes.

RESUMO

Histological grade and depth of invasion are among the best outcome pathological predictors in penile cancer. The TNM system is based on a combination of both for some stages. It is assumed that high-grade and deep tumors carry the worst prognosis, and the opposite occurs with superficial and low-grade neoplasms. However, there is no systematic evaluation of the phenomenon. We studied 147 patients from the Hospital de Oncologia - Instituto Mexicano del Seguro Social (period 2000 to 2013). They were treated by total or partial penectomies. Lymph node involvement was evaluated by bilateral inguinal node dissection (126 cases) or ultrasonography (21 cases). Tumor thickness was measured in mm from tumor surface to deepest invasion point, using a cut-point for superficial (≤10 mm) vs deep (>10 mm) tumors. Histological grade was from 1 to 3 according to WHO and AFIP criteria and considering G1 and G2 as low-grade and G3 as high-grade. Average age was 62 (26-98) years old. Tumor thickness mean was 15 mm (2-30 mm). G1, G2 and G3 tumors corresponded to 19 (13 %), 48 (33 %), and 80 (54 %) cases, respectively. Follow-up ranged from 10 to 82 months (median: 57 months). Fifty-three (36 %) patients died of disease. There was an overall correlation of tumor thickness and grade in most of the cases. Low-grade tumors were encountered in 92 % (12/13 cases) of superficial tumors. Deep tumors showed high-grade in 75 % of cases (73/97 cases). Superficial tumors with low histological grade had negative inguinal nodes and no mortality whereas deep tumors showing high histological grade were associated with high metastatic risk to lymph nodes (62/73 cases) and mortality (52/73 cases). Out of 24 deep tumors with low histological grade, seven had nodal spread (29 %) but only one died of disease. No outcome difference was found in HPV associated vs HPV independent tumors. Tumor thickness and grade are important synergistic and predictive pathological factors in relation to prognosis.

RESUMO

PURPOSE: Penile cancer is a rare malignancy, where extranodal extension in inguinal or pelvic lymph nodes is associated with decreased 5-year cancer-survival rate in this study, we try to assess survival and quality of life in a penile cancer patient with bulky lymph node. METHODS: We retrospectively reviewed data from penile cancer patients with bulky lymph nodes who underwent treatment between July 2016 and July 2021 at tertiary referral hospital care. The inclusion criteria (age >18 yr, histologically proven penile cancer, and completion of last treatment 6 months prior to this study) yielded a cohort of 20 eligible penile cancer patients with bulky lymph nodes (> 4 cm/bilateral mobile/unilateral fixed). Only patients who had completed therapy at least 6 months prior to the study were included. After obtaining consent, they were asked to complete the EORTC QLQ-C30 questionnaire to evaluate the patient's quality of life. RESULTS: Out of 20 patients, 5 patients underwent direct ILND and 15 patients underwent chemotherapy. Median follow-up after primary diagnosis was 114+32 months in patients with early ILND and 52+11 months in patients who underwent delayed lymph node dissection. Out of 5 patients who underwent early ILND, all of them survived during follow-up, and achieved cancer-free status without residual tumor and with excellent functional outcomes (Karnofsky 90). There was no significant difference in social function (p-value = 0.551), physical function (p-value = 0.272), role function (p-value = 0.546), emotional function (p-value = 0.551), cognitive function (p-value = 0.453), and global health status (p-value = 0.893) between patient which treated with early ILND and Neoadjuvant Chemotherapy. However, patients who underwent early ILND showed a relatively better clinical outcome. CONCLUSION: Early ILND followed by adjuvant chemotherapy for penile cancer with palpable lymph nodes is more favourable than neoadjuvant TIP chemotherapy.

RESUMO

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.

RESUMO

BACKGROUND: Penile carcinoma is an uncommon cancer that develops in the penis tissue. The standard surgical method to manage regional lymph nodes after local excision is radical inguinal lymphadenectomy, but it has a high rate of complications. The objective of this retrospective study was to compare the long-term outcomes of endoscopic inguinal lymphadenectomy and open inguinal lymphadenectomy in patients with penile carcinoma. METHODS: The study included patients diagnosed with penile carcinoma who underwent open inguinal lymphadenectomy (n = 23) or endoscopic inguinal lymphadenectomy (n = 27) at a single hospital between January 2013 and January 2021. Operation time, blood loss, drainage, hospital stay, postoperative complications, and survival rates were assessed and compared between the two groups. RESULTS: The two groups were comparable in terms of age, tumor size and stage, inguinal lymph nodes, and follow-up. The endoscopic group had significantly lower blood loss (27.1 ± 1.5 ml vs 55.0 ± 2.7 ml, P < 0.05), shorter drainage time and hospital stay (4.7 ± 1.1 days vs 8.1 ± 2.2 days, and 13.4 ± 1.0 days vs 19 ± 2.0 days, respectively, P < 0.05), and longer operation time compared to the open group (82.2 ± 4.3 min in endoscopic group vs 53.1 ± 2.2 min in open group, P < 0.05). There were significant differences in the incidence of incisional infection, necrosis, and lymphorrhagia in both groups (4 vs 0, 4 vs 0, and 2 vs 0, respectively, P < 0.05). The inguinal lymph node harvested was comparable between the two groups. The mean follow-up time was similar for both groups (60.4 ± 7.7 m vs 59.8 ± 7.3 m), and the recurrence mortality rates were not significantly different. CONCLUSIONS: The study shows that both open and endoscopic methods work well for controlling penile carcinoma in the long term. But the endoscopic approach is better because it has fewer severe complications. So, the choice of surgery method might depend on factors like the surgeon's experience, what they like, and what resources are available.

RESUMO

OBJECTIVE: This study investigated disease-free survival and oncological outcomes in penile cancer patients treated surgically at a high-volume center and identified the prognostic factors for disease-free survival. METHODS: A retrospective analysis was conducted on primary penile cancer patients diagnosed and treated at Songklanagarind Hospital, Thailand, between January 2001 and December 2021. Disease-free survival (DFS) was assessed using Kaplan-Meier survival curves, and Cox proportional hazard models were used for multivariate analysis. RESULTS: The study included 188 patients with primary penile cancer. The majority (98.4%) were uncircumcised. Tumor staging revealed 40.6% with T1 tumors, 72.9% with well-differentiated tumors, and 23.5% diagnosed at stage IIIA. The recurrence rate was 19.1%, with a mean time to recurrence of 25.9 months. Disease-free survival rates at 1, 3, and 5 years were 81.1%, 70.9%, and 70.9%, respectively. Median overall survival was 16.43 months, with survival rates at 1, 3, and 5 years at 67.7%, 42.7%, and 35.4%, respectively. Cox proportional hazard models showed significant associations between disease-free survival and a higher T stage, a high level of CRP (>15 mg/L), delayed onset of symptoms, primary lesion location, groin node metastasis, lymphovascular invasion, and pelvic lymph node metastases. However, multivariate analysis revealed that a higher primary tumor stage (T) was the only independent prognostic factor for disease-free survival. CONCLUSION: This study presents one of the largest cohorts investigating disease-free survival outcomes in penile cancer treatment at a single institution over a prolonged period. A higher pathologic T stage is a significant prognostic factor for disease-free survival. Further large-scale prospective studies are needed for validation.

RESUMO

BACKGROUND: Penile cancer (PeCa) represents a diagnostic and therapeutic challenge given the low patient volume, which may result in inadequate physician expertise and poor guideline adherence. Since 2015, we have developed a specific care pathway for PeCa in our tertiary referral center. OBJECTIVE: To evaluate the impact of a dedicated PeCa care pathway on patient management, the adequacy of pathological reporting, and oncological outcomes. DESIGN, SETTING, AND PARTICIPANTS: We retrospectively queried our institutional registry (S-66482) to identify patients who were surgically treated for PeCa between January 1989 and April 2022. The patient numbers were evaluated within a broader national context. OUTCOME MEASUREMENTS AND STATISTICAL ANALYSIS: We compared patient, surgery, tumor, and pathological data before and after 2015. Kaplan-Meier analysis was used to compare local and regional recurrence rates and cancer-specific survival (CSS). RESULTS AND LIMITATIONS: Overall, 313 patients were included, of whom 204 (65.1%) were surgically treated after 2015. The median number of patients treated yearly was significantly higher after 2015 (26 vs 5; p < 0.01). Patients treated after 2015 more frequently had no palpable lymph nodes at diagnosis, despite similar primary tumor stage. After adoption of the PeCa care pathway, organ-sparing surgery (OSS) was more commonly performed (79.9% vs 57.8%; p < 0.01) despite local staging being similar and without observing a significant increase in positive margins. Surgical staging in patients with European Association of Urology intermediate- or high-risk tumors was conducted more frequently after 2015 (90% vs 41%; p < 0.01). Pathology reporting was standardized, and there was more frequent reporting of p16 staining status (81.4% vs 8.3%; p < 0.01), lymphovascular invasion (93.8% vs 44.3%; p < 0.01), and perineural invasion (92.4% vs 44.3%; p < 0.01) following implementation. CONCLUSIONS: Implementation of a standardized care pathway for PeCa resulted in higher rates of OSS and pathological nodal staging and more complete pathology reports. Considering that these changes were associated with an increase in the number of patients treated, academic-driven centralization may play a role in optimizing the management of these patients. PATIENT SUMMARY: We evaluated the impact of a care pathway for patients with penile cancer on patient management, the completeness of pathology reporting, and cancer control. We found that implementation of this pathway was associated with an increase in the number of patients treated, higher rates of organ-sparing surgery and lymph node staging, and more complete pathology reports. Centralization of care may play a role in optimizing the management of penile cancer.

RESUMO

Penile squamous cell carcinoma (PSCC) is a rare malignancy with poor outcomes in advanced stages, with dismal response and survival rates using conventional surgical and systemic options. Additionally, the ability to detect and monitor residual disease with current imaging modalities remains difficult. Therefore, advances in multimodal management and disease monitoring are desperately needed. We present a case of advanced PSCC utilizing multimodal management informed by next-generation sequencing and circulating tumor DNA monitoring. These genomic techniques were valuable in guiding management and deserve further evaluation in the management of PSCC and other rare malignancies.

RESUMO

OBJECTIVES: To investigate the safety and efficacy of indocyanine green (ICG) fluorescence-guided inguinal lymph node dissection (ILND) in patients with penile cancer. PATIENTS AND METHODS: A prospective, single-blind, randomised controlled clinical trial (ChiCTR2100044584) was performed among patients with penile caner who underwent bilateral modified ILND at four centres in China between 1 April 2021 and 30 June 2022. Patients aged 18-80 years and diagnosed with squamous cell carcinomas were included. Each enrolled patient was randomly assigned to either ICG fluorescence-guided ILND by a laparoscopic or robot-assisted approach in one groin, with non-ICG fluorescence-guided ILND in the other groin acting as a control. The primary outcome was the number of retrieved ILNs. Secondary outcomes included complications according to the Clavien-Dindo classification and the ILN non-compliance (inadequate removal of ILNs) rate. RESULTS: A total of 45 patients were included in the intention-to-treat (ITT) analysis, and the 42 who completed the entire study were included in the per protocol (PP) analysis. There were no ICG-related complications in any of the patients. The results of the ITT and PP analyses indicated that the total number of unilateral ILNs retrieved was higher on the ICG side than on the non-ICG side (mean 13 vs 9 ILNs, difference 4 ILNs [95% CI 2.7-4.4], P = 0.007), and the number of unilateral deep and superficial ILNs was higher on the ICG side. Furthermore, the LN non-compliance rate was lower on the ICG side than on the non-ICG side. Additionally, there was no significant difference in local complications in the groins between the two sides (P > 0.05). CONCLUSION: An ICG fluorescence-guided ILND was safe for patients with penile cancer. This procedure can improve the number of ILNs retrieved and reduce the LN non-compliance rate without increased complications. ICG fluorescence-guided ILND is beneficial and recommended for selected patients with penile cancer.

RESUMO

BACKGROUND: Men with localized invasive penile cancer (PC) can be treated with organ-sparing treatments with different functional and aesthetical outcomes. Thus, the aim of this study is to investigate sexual outcomes in patients with PC confined to the glans that underwent wide local excision (WLE) vs. glansectomy with urethral glanduloplasty. METHODS: Complete data from 60 patients with PC were analyzed at our institution from 2017 to 2022. Patients were asked for personal habits and clinical features. PC was assessed with a clinical visit and imaging techniques. At the outpatient follow-up visit or phone call, all patients compiled the Changes in Sexual Function Questionnaire (CSFQ) and the International Index of Erectile Function in its short 5-item form (IIEF-5). Erectile function (EF) impairment was categorized using Cappelleri's criteria. RESULTS: Overall, 34 patients with PC confined to the glans (c ≤ T2N0) were included. Of those, 12 underwent WLE and 22 underwent glansectomy with urethral glanduloplasty. Using multivariable logistic regression, glansectomy (OR: 3.49) and diabetes (OR: 2.33) were associated with erectile disfunction (IEEF < 22). Meanwhile, using multivariable linear regression analysis, younger patients (Coeff: -2.41) and those that underwent glansectomy (Coeff: -7.5) had a higher risk of sexual function impairment, according to the CSFQ. CONCLUSIONS: Patients with PC ≤ T2N0 that underwent WLE have better outcomes in terms of sexual functioning than the patients who underwent glansectomy and uretheral gladuloplasty. Further research is needed to clarify the outcomes of penile-sparing surgery, to inform patients in pre-surgical counseling more comprehensively, and to meet their post-operative expectations more effectively.

RESUMO

Objetivo: proporcionar reflexões sobre o cuidado de enfermagem com abordagem à sexualidade para a saúde do homem penectomizado por câncer de pênis. Conteúdo: corresponde a estudo reflexivo construído a partir de leituras em produções científicas sobre o cuidado de Enfermagem e a sexualidade para o paciente oncológico penectomizado, à luz dos pensamentos e pressupostos ontológicos e teóricos de Martin Heidegger. Considerações finais: as novas condições impostas pelo adoecimento por câncer de pênis e o tratamento mutilador, a penectomia, exigem uma Enfermagem que aborde a sexualidade, considerando o indivíduo em sua totalidade e com ênfase no cuidado com perspectiva na profundidade e subjetividade existenciais humanas(AU)


Objective: to provide reflections on nursing care with an approach to sexuality for the health of men undergoing penectomy for penile cancer. Content: reflective study developed from readings in scientific productions on Nursing care and sexuality for the penectomized cancer patient, in the light of Martin Heidegger's ontological and theoretical thoughts and assumptions. Final considerations: the new conditions imposed by illness from penile cancer and the mutilating treatment, penectomy, require Nursing that addresses sexuality, considering the individual in its entirety and with an emphasis on care with a perspective on human existential depth and subjectivity(AU)

RESUMO

OBJECTIVE: to trace the clinical and epidemiological profile of penile cancer in Rio Grande do Norte/Brazil and relate them to data published in the literature. METHODS: a cross-sectional study was conducted with 94 patients diagnosed with penile cancer in 2011-2018, treated at the Liga Norte Riograndense Contra o Cancer. RESULTS: all patients were diagnosed with squamous cell carcinoma, mainly aged over 50 years, from the states interior, brown, illiterate, or with incomplete primary education. At diagnosis, 68% of patients were classified as having tumors =T2, and 30% had lymph node involvement. Distant metastases were detected in 2.1% of patients at diagnosis. Most patients received the diagnosis in the initial phase of the disease, but 20.2% were diagnosed in stage IV. Partial penectomy was the most performed surgery, and 10% of patients relapsed, mainly in the lymph nodes (87.5%). The mean follow-up of the patients was 18 months, with an estimated overall survival at five years of 59.1%. However, 25% of patients were followed up for up to 3 months, losing follow-up. CONCLUSION: the State of Rio Grande do Norte has a high incidence of penile cancer with a high frequency of locally advanced tumors at diagnosis and in younger patients younger than 50. Furthermore, socioeconomic factors interfere with early diagnosis and hinder access to specialized services.

RESUMO

OBJECTIVES: There is an unmet need for therapeutically relevant biomarkers for advanced penile squamous cell carcinoma (pSCC). Proposed immunohistochemistry (IHC)-based biomarkers include programmed death-ligand 1 (PD-L1), trophoblast cell-surface antigen 2 (TROP2), and nectin-4; however, there is a paucity of data pertaining to these biomarkers. Herein, we investigated the expression of PD-L1, TROP2, and nectin-4 in a well-annotated cohort of pSCCs. METHODS: A single-institution pathology archive was queried for patients who had a partial or total penectomy for pSCC between January 2000 and December 2022. Whole-slide sections were stained with antibodies against PD-L1 (22C3), TROP2, and nectin-4. Expression in tumor cells was quantified using H-scores (0-300). Associations between IHC expression, human papilloma virus (HPV) status, clinicopathologic findings, and outcome parameters were evaluated. RESULTS: This study included 121 patients. For PD-L1, the median combined positive and H-scores were 1 and 0, respectively; 32.7 % of the cases had an H-score>0. Compared to PD-L1-negative tumors, PD-L1-positive tumors had higher pT stage and grade. The median TROP2 and nectin-4 H-scores were 230 and 140, respectively, with high TROP2 and nectin-4, defined by an H-score>200, noted in 80.7 % and 10.9 % of cases, respectively. High-risk HPV-positive cases had higher TROP2 and nectin-4 scores compared to HPV-negative cases. Patients with high TROP2 expression had significantly more disease progression, and patients with high nectin-4 expression had significantly fewer deaths due to disease. CONCLUSIONS: High expression of TROP2 and nectin-4 in pSCC support evaluation of these markers as therapeutic targets pending validation of our findings.
