KOL-Index: 14277 . PURPOSE: Sentinel node biopsy is used to evaluate the nodal status of patients with clinically node-negative penile carcinoma. Its use is not widespread, and the majority of patients with clinically node-negative disease undergo an elective inguinal lymph node dissection. Reservations about the use of sentinel node biopsy include the fact that most current results come from one institution ...

KOL-Index: 13448 . BACKGROUND: The European Association of Urology (EAU) guidelines advise an elective bilateral lymphadenectomy in clinically node-negative (cN0) patients with high-risk penile carcinoma (≥pT2, G3, or lymphovascular invasion [LVI]). OBJECTIVE: Our aim was to assess prognostic factors for occult metastasis and to determine whether current EAU guidelines accurately stratify patients at high ...

KOL-Index: 10284 . BACKGROUND: Dynamic sentinel node biopsy (DSNB) in combination with ultrasound scan (USS) has been the technique of choice at our centre since 2004 for the assessment of nonpalpable inguinal lymph nodes (cN0) in patients with squamous cell carcinoma of the penis (SCCp). Sensitivity and false-negative rates may vary depending on whether results are reported per patient or per node basin, ...

KOL-Index: 9766 . CONTEXT: Penile cancer has high mortality once metastatic spread has occurred. Local treatment can be mutilating and devastating for the patient. Progress has been made in organ-preserving local treatment, lymph node management, and multimodal treatment of lymphatic metastases, requiring an update of the European Association of Urology guidelines. OBJECTIVE: To provide an evidence-based ...

KOL-Index: 9000 . BACKGROUND: Urethral stricture is a common cause of difficulty passing urine in men with prevalence of 0.5 %; about 62,000 men in the UK. The stricture is usually sited in the bulbar part of the urethra causing symptoms such as reduced urine flow. Initial treatment is typically by endoscopic urethrotomy but recurrence occurs in about 60% of men within 2 years. The best treatment for men ...

KOL-Index: 8460 . BACKGROUND: A systematic literature review did not identify a formally validated patient-reported outcome measure (PROM) for urethral stricture surgery. OBJECTIVE: Devise a PROM for urethral stricture surgery and evaluate its psychometric properties in a pilot study to determine suitability for wider implementation. DESIGN, SETTING, AND PARTICIPANTS: Constructs were identified from ...

KOL-Index: 8364 . CONTEXT: Management of men with penile squamous cell carcinoma (PSCC) who have high-risk features following radical inguinal lymphadenectomy (ILND) remains controversial. European Association of Urology guidelines state that adjuvant inguinal radiotherapy (AIRT) is "not generally recommended". Despite this, many centres continue to offer AIRT to a subset of men. OBJECTIVE: To undertake a ...

KOL-Index: 7941 . BACKGROUND: Studies of interventions for urethral stricture have inferred patient benefit from clinician-driven outcomes or questionnaires lacking scientifically robust evidence of their measurement properties for men with this disease. OBJECTIVE: To evaluate urethral reconstruction from the patients' perspective using a validated patient-reported outcome measure (PROM). DESIGN, SETTING, ...

KOL-Index: 7577 . AIMS: To determine whether Ki-67 immunoexpression in penile squamous cell carcinoma (PSCC) has a prognostic value and correlates with lymph node metastasis, human papillomavirus (HPV) infection and patient survival. METHODS: 148 formalin-fixed paraffin-embedded PSCC samples were tissue-microarrayed, including 97 usual-type SCCs, 17 basaloid, 15 pure verrucous carcinomas, 2 warty and 17 ...

KOL-Index: 6878 . IntroductionThe management of the regional lymph nodes in penile cancer patients, particularly when these lymph nodes are impalpable, remains controversial. Prophylactic bilateral inguinal lymphadenectomy is associated with high morbidity and is often unnecessary. However, there is no non-invasive or minimally invasive staging technique that can determine the lymph node status of penile ...

KOL-Index: 6754 . BACKGROUND: Urethral stricture affects 0.9% of men. Initial treatment is urethrotomy. Approximately, half of the strictures recur within 4 yr. Options for further treatment are repeat urethrotomy or open urethroplasty. OBJECTIVE: To compare the effectiveness and cost-effectiveness of urethrotomy with open urethroplasty in adult men with recurrent bulbar urethral stricture. DESIGN, SETTING, ...

KOL-Index: 6286 . OBJECTIVES: To improve the prognostic allocation of patients with penile squamous-cell carcinoma (PSCC) receiving regional lymph node dissection (LND). PATIENTS AND METHODS: An international, multicenter, retrospective study was performed on patients with PSCC who received regional LND, with or without perioperative therapy, from 1980 to 2017. We first used a random forest (RF) method with ...

KOL-Index: 6145 . OBJECTIVE: To develop a novel postoperative prognostic tool, which attempts to integrate both pathological tumour stage and histopathological factors, for prediction of cancer-specific mortality (CSM) of squamous cell carcinoma of the penis (SCCP). PATIENTS AND METHODS: Patients with SCCP treated with inguinal lymph node dissection (ILND) or sentinel LN biopsy at a single institution were ...

KOL-Index: 5978 . OBJECTIVE: To evaluate the significance of close surgical margins in organ-sparing surgery (OSS) in the treatment of penile squamous cell carcinoma (pSCC) and clinicopathological factors that may influence local recurrence. PATIENTS AND METHODS: At our tertiary referral centre, between March 2001 and September 2012, 332 patients treated with OSS for pSCC had clear surgical margins. As the ...

KOL-Index: 5915 . OBJECTIVE: To examine the tissue expression of DNA topoisomerase I (Topo I) and IIalpha (Topo II), to pursue the possibility of future chemotherapy regimens for squamous cell carcinoma of the penis (SCCP), as high expression of Topo I might indicate sensitivity to the camptothecins, whereas high Topo II might indicate sensitivity to etoposide. PATIENTS AND METHODS: In all, 73 patients with ...
