Meta-Analysis Review Comparative Study
BACKGROUND
En-Bloc transurethral resection of bladder tumor (ERBT) was clinically used to resect non-muscle-invasive bladder cancer (NMIBC). However, discrepancies persist regarding the comparisons between ERBT and conventional transurethral resection of bladder tumor (cTURBT).
METHODS
We conducted a comprehensive search in PubMed, Embase, Web of Science, Cochrane Database of Systematic Reviews, and performed manual searches of reference lists to collect and extract data. Data evaluation was carried out using Review Manager 5.4.0, Rx64 4.1.3, and relevant packages.
RESULTS
There were nine eligible meta-analyses and nine eligible RCTs in our study. NMIBC patients undergoing ERBT were significant associated with a lower rate of bladder perforation and obturator nerve reflex compared to those receiving cTURBT. Our pooled result indicated that ERBT and cTURBT required similar operation time. Regarding postoperative outcomes, ERBT demonstrated superior performance compared to cTURBT in terms of detrusor muscle presence, catheterization time, and residual tumor. ERBT exhibited a higher rate of three-month recurrence-free survival (RFS) compared to those receiving cTURBT (p < 0.05; I = 0%). In bipolar subgroup, ERBT had a significant better 12-month RFS than cTURBT (p < 0.05; I = 0%). Simultaneously, the exclusion of Hybrid Knife data revealed a significant improvement in 12-month RFS associated with ERBT (p < 0.05; I = 50%).
CONCLUSION
Using a combination of umbrella review and meta-analysis, we demonstrated that ERBT had better or comparable perioperative outcome and improved 3 and 12 month RFS than cTURBT. We suggest that ERBT maybe a better surgical method for patients with NMIBC compared with cTURBT.

Comparative Study
The staging for pT2/pT3 penile squamous cell carcinoma (pSCC) has undergone major changes. Some authors proposed criteria wherein the distinction between pT2/pT3 was made using the same histopathological variables that are currently utilized to differentiate pT1a/pT1b. In this single-institution, North American study, we focused on (HPV-negative) pT2/3 pSCCs (i.e., tumors invading corpus spongiosum/corpus cavernosum), and compared the prognostic ability of the following systems: (i) AJCC (8th edition) criteria; (ii) modified staging criteria proposed by Sali et al. (Am J Surg Pathol. 2020; 44:1112-7). In the proposed system, pT2 tumors were defined as those devoid of lymphovascular invasion (LVI) or perineural invasion (PNI), and were not poorly differentiated; whereas pT3 showed one or more of the following: LVI, PNI, and/or grade 3. 48 pT2/pT3 cases were included (AJCC, pT2: 27 and pT3: 21; Proposed, pT2: 22 and pT3: 26). The disease-free survival (DFS) and progression-free survival (PFS) did not differ between pT2 and pT3, following the current AJCC definitions (p = 0.19 and p = 0.10, respectively). When the pT2/3 stages were reconstructed using the modified criteria, however, a statistically significant difference was present in both DFS and PFS between pT2 and pT3 (p = 0.004 and p = 0.003, respectively). The proposed staging system has the potential to improve the prognostication of pT2/pT3 tumors in pSCC. Each of these histopathologic variables has been shown to have a significant association with outcomes in pSCC, which is an advantage. Further studies are needed to demonstrate the utility of this modified staging system in patient populations from other geographic regions.

Hereby, we present a rare case of malignant transformation in a long-standing case of pseudoepitheliomatous keratotic and micaceous balanitis (PKMB), which typically affects older men. PKMB presents as whitish or silvery keratotic plaques on the glans and can remain stable for years, leading to potential confusion regarding its progression. The patient in this case experienced urinary obstruction due to tumorous ingrowth, prompting an investigation. Despite previous treatments, including fluorouracil (5-FU) and cryoablation, the lesion persisted, eventually growing in size and becoming malodorous. Initial biopsy showed PKMB without malignancy, but subsequent deeper biopsy revealed verrucous carcinoma. The patient underwent glansectomy and reconstruction with a full-thickness skin graft, achieving a disease-free state postoperatively. The paper underscores the importance of thorough investigation for malignancy in PKMB cases, the possibility of deeper malignancy missed by superficial biopsy, and the need for early diagnosis to enable organ-sparing treatments.

Correlation between urine cytology results on the day after overnight continuous saline irrigation following transurethral resection of bladder tumor and bladder tumor recurrence.
PURPOSE
To investigate the relationship between urine cytology results after overnight continuous saline irrigation (OCSI) following transurethral resection of bladder tumor (TURBT) and bladder tumor recurrence in non-muscle invasive bladder cancer (NMIBC).
MATERIALS AND METHODS
A retrospective study was conducted on patients diagnosed with NMIBC between 2016 and 2020 after undergoing TURBT at our hospital. All patients received OCSI following TURBT and had urine cytology test at postoperative 1 day. Urine cytology was classified into three groups: Negative, low-grade urothelial neoplasm (LGUN)+atypical urothelial cells (AUC), and suspicious for high-grade urothelial carcinoma (SHGUC)+high-grade urothelial carcinoma (HGUC). Recurrence-free survival (RFS) in each group was compared using the Kaplan-Meier method. Univariable and multivariable Cox regression analyses were performed to evaluate independent prognostic factors.
RESULTS
A total of 172 patients were included in this study. Based on urine cytology group (after OCSI), RFS did not reach the median value in the Negative group. In the LGUN+AUC group, the median RFS was 615.00 days. In the SHGUC+HGUC group, the median RFS was 377.00 days. In survival analysis, the Negative group had a longer RFS than the SHGUC+HGUC group (p=0.013). However, Cox regression analysis showed that SHGUC+HGUC was not an independent prognostic factor for recurrence.
CONCLUSIONS
Urine cytology results after OCSI following TURBT in NMIBC were associated with bladder tumor recurrence. Specifically, SHGUC or HGUC in urine cytology after OCSI showed earlier recurrence than negative cases. However, further research is needed to accurately determine whether it is an independent prognostic factor.

Cancer of the penis is a rare tumor that occurs in the elderly. Because of its rarity, it is often not diagnosed early, and its treatment poses difficulties for practicing oncologists. We report the case of an elderly patient treated for locally advanced squamous cell carcinoma (SCC) of the penis, with a review of the literature. A 71-year-old man, who had been complaining of pruritus on the penis two years ago, presented with an ulcerated lesion on the prepuce and the glans. A biopsy of the lesion with pathological study showed a SCC of the penis. Pelvic MRI showed tumor thickening centered on the glans of the penis, infiltrating the fascia and the spongy urethra with discrete upstream dilatation and bilateral inguinal adenomegaly. CT scan of the neck, chest, abdomen, and pelvis showed no secondary localizations. Treatment initially consisted of carcinological surgery by a partial penectomy with bilateral inguinal lymph node dissection. The tumor was therefore classified as pT3N3M0. A PET CT scan performed later was in favor of local and regional recurrence. Surgery was not feasible, so concomitant chemo-radiotherapy was indicated at a total dose of 70 Gy in 35 fractions of 2 Gy concomitantly with platinum-based chemotherapy, withgood evolution.

INTRODUCTION
Bowen's disease (BD) represents an in situ squamous cell carcinoma that can progress to an invasive one without treatment. Various options for Bowen's disease have been delineated, each with its set of advantages and disadvantages.
CASE PRESENTATION
We report the case of a 60-year-old patient with a history of chronic smoking and a background of multiple partners and recurrent urethritis. The patient presented with a maculopapular lesion on the lateral aspect of the penis, evolving for 5 years. A biopsy confirmed the diagnosis of Bowen's disease. The patient underwent an excision of the lesion which the histology showed an infiltrating basosquamous cell carcinoma.
DISCUSSION
The diagnosis of Bowen's disease requires a biopsy and is based on histological examination. Only surgical treatment allows for the identification, through histological analysis of the excised specimen, of any potential invasive area that may not have been identified in the biopsy. Nonsurgical therapies are also an option with high recurrence rates.
CONCLUSION
Bowen's disease management requires a personalized approach, considering factors like lesion characteristics, patient-related variables and treatment efficacy. An adapted follow-up is recommended due to the recurrence risk associated with various treatments.

Review
Metastasis to the penis from renal cell carcinoma (RCC) or any other primary cancer site is unusual; when it does occur, it often involves multiple organs. A 75-year-old man presented with penile pain and swelling. Three months earlier, he had open radical nephrectomy with thrombectomy and was diagnosed with clear-cell RCC with tumor thrombosis in the inferior vena cava. The follow-up imaging indicated metastasis to the penis, prompting a total penectomy due to worsening pain. The excised mass displayed features consistent with metastatic RCC. This case underscores the need to consider rare metastatic sites, such as the metastasis of RCC to the penis, in RCC patients.

To report outcomes of multicenter series of penile cancer patients undergoing robot-assisted video endoscopic inguinal lymph node dissection (RA-VEIL). In this retrospective analysis from 3 tertiary care centers in India, consecutive intermediate-/high-risk carcinoma penis (CaP) patients with nonpalpable inguinal lymphadenopathy and/or nonbulky (<3 cm) mobile inguinal lymphadenopathy undergoing RA-VEIL were included. Patients with matted/bulky (>3 cm) and fixed lymphadenopathy were excluded. Demographic, clinical, and intraoperative data were recorded. Perioperative complications were graded by the Clavien-Dindo classification (CDC). The International Society of Lymphology (ISL) {0-III} grading was used for the assessment of lymphedema. Incidence and pattern of recurrences were assessed on follow-up. From January 1, 2011, to September 30, 2023, 115 patients (230 groins) underwent bilateral RA-VEIL for CaP. The median age of the cohort was 60 (50-69) years. Clinically palpable (either unilateral or bilateral) inguinal lymphadenopathy was seen in 54 patients (47%). The "per groin" median operative time was 120 (100-140) minutes with median lymph node yield of 12 (9-16). No complications were recorded in 87.8% groins operated, with major complications (CDC 3) seen in 2.6% groins. At a median follow-up of 13.5 months, 13 patients had documented recurrences and there were 10 cancer-related deaths. No port-site recurrences were observed. No/minimal lymphedema (ISL 0/I) was seen in 94% legs. RA-VEIL demonstrates safety and oncologic efficacy in penile cancer patients presenting with clinically nonpalpable and/or nonbulky inguinal lymphadenopathy, with favorable functional outcomes.

Cytomegalovirus (CMV) infection is common and often self-limited. Reactivation results in a variety of disease presentations, especially in the setting of immunocompromise. While cutaneous manifestations of systemic CMV infection are rare, dermatologic manifestations of CMV are increasingly reported with a wide morphologic spectrum clinically. Three male patients, with untreated human immunodeficiency virus (HIV), penile lichenoid dermatitis treated with long-term topical and intralesional corticosteroids, and metastatic Merkel cell carcinoma on immune checkpoint inhibitor therapy, each presented with isolated cutaneous ulcers. The ulcers were located on the perianal skin, glans of the penis, and distal thumb. In each case, nonspecific histopathologic features were seen. However, very rare dermal cytomegalic cells with nuclear and cytoplasmic inclusions were present and highlighted with an immunohistochemical stain for CMV. Isolated ulcers due to CMV infection may occur in the setting of systemic or localized immunosuppression. A high index of suspicion is needed upon histopathologic evaluation, as few cytomegalic cells may be present and accurate diagnosis is crucial for prompt and appropriate clinical management.

Urethral cancer after urethral reconstruction is an under-recognized, uncommon disease associated with significant morbidity and mortality. The survival rates of patients with carcinoma of the bulbar urethra are as low as 20%-30%. Stricture recurrence and unrecognized malignant changes present prior to reconstruction are major risk factors for urethral cancer. Skin substitution urethroplasty is subjected to higher rates of recurrence, which lends to the potential for carcinogenesis. We present a case of a 59-year-old male who underwent multi-stage skin substitution urethroplasty who developed urethral carcinoma 20 years later.
