Penectomía parcial y reconstrucción peneana. Manejo quirúrgico inicial del cáncer de pene localizado

IntroductionSurgical management for penile carcinoma is mutilating and affects significantly quality of life. Hereby we present our experience on penile reconstruction (PR) immediately after oncologic resection.Materials and methodsWe included all patients from January 2007 until April 2012 who underwent PR after partial penectomy (PP). Patients included in the study were seen at four different hospitals. All procedures were done by the same surgeon. Information included were: oncological status at the moment of surgery, surgical technique used for reconstruction. Each case was also registered photographically. On follow-up visits data about outcome and patient's satisfaction were registered.ResultsDuring the study period 15 patients underwent PR. Average age at the moment of surgery was 49 years. Average follow-up was 15 months. In 12 patients PR was made at the same time as PP. Of those, four cases underwent glans resurfacing, 2 glandectomy, 6 partial penectomy, and the remaining 3 have had PP in a different time in the past. Every case underwent a split thickness graft procedure. Only 2 patients had postoperative complications. One of them presented urethral stricture and the other graft ischemia. Three patients had positive nodes at the moment of PP and two during the follow-up. None of the cases have presented local recurrence and only one died. On follow-up the remaining patients refer a good quality of life and felt happy with aesthetic results.ConclusionsGiven the results presented hereby we propose that PR must be part of the same procedure as the PP.

C-MET is expressed in the majority of penile squamous cell carcinomas and correlates with polysomy-7 but is not associated with MET oncogene amplification,pertinent histopathologic parameters,or with cancer-specific survival

We assessed c-MET expression and oncogene amplification in a cohort enrolling 92 surgically treated penile squamous cell carcinomas (PSCCs). A tissue microarray was constructed for c-MET immunohistochemistry (IHC) and chromogenic silver in situ hybridization (SISH). Two independent pathologists evaluated IHC by employing the breast cancer scoring rules, and scored the presence of MET oncogene amplification and/or polysomy-7. Eighty study cases (87%) showed c-MET expression. No study case had MET oncogene amplification, but 42 patients (45.7%) had polysomy-7. Polysomy-7 showed a significant positive correlation with c-MET expression (ρ = 0.323, p = 0.002). Neither c-MET expression nor polysomy-7 was associated with histopathologic parameters or with cancer-specific survival (median post-surgical follow-up 32 months). Our data suggest that the majority of PSCCs exhibit c-MET expression which is not associated with oncogene amplification, but might be attributable to polysomy-7. Further studies should investigate the expression and activation of downstream molecules functionally involved in c-MET pathway signaling, and clarify the so far unresolved role of c-MET inhibitors as potential targeted therapies in PSCCs with metastatic dissemination.

Diseño y evaluación de un modelo de simulación de fractura de pene

ObjectiveTo design and assess a novel penile fracture simulation model for teaching penile fracture repair.MethodsWe used a validated circumcision simulator to create a model. Foreskin for a circumcision was divided into two halves. A transverse slit (“simulated fracture”) was created on one part of the first half of the foreskin (mimicking “tunica”) and was applied over the penile model. A red jelly tablet (“clot”) was placed underneath the cut. A second full-length of foreskin was applied over it to cover the defect. The model was assessed by participants and expert faculty at the Urology Simulation Boot Camp. Evaluation was performed using a 5-point Likert Scale questionnaire. Data was analysed using Microsoft Excel and IBM SPSS Statistics V25. The intra-class correlation was calculated using a “One-way random model”.ResultsTwenty-two urology trainees and four experts participated in the evaluation. The majority of trainees strongly agreed (59%, n = 13) the model is useful for training with experts similarly agreeing in 75% of cases. The appearance of penile fracture was considered good by both trainees (68%, n = 14) and faculty (75%). Overall, the ability of the model to represent a realistic simulation of the task was considered excellent by 23% of participants and good by 64%. Personal confidence after simulation in managing a similar situation was considered high among trainees. The main difficulties reported were related to fascial planes and urethra.ConclusionThis is the first simulation model for penile fracture repair and has demonstrated face validity at a national urology bootcamp.     

Free Bipedicled Radial Forearm and Posterior Interosseous Artery Perforator Flap Phalloplasty

IntroductionThe free radial forearm (FRFA) flap is universally still considered as the gold standard technique in penile reconstruction. Typically, a considerably large flap is required, often involving almost the entire circumference of the forearm. Partial necrosis may occur at the distal-most (dorsoradial) part of the flap as a result of insufficient perfusion.AimTo describe a new technique using the posterior interosseous artery (PIOA) to supercharge FRFA phalloplasty.MethodsIn a 12-month period, all patients having FRFA flap phalloplasty were enrolled. Perioperative, after complete flap dissection, an indocyanine green perfusion scan was performed. In case of insufficient perfusion at the distalmost part of the flap, a supramicrosurgical anastomosis was performed between the FRFA pedicle and the PIOA (artery only).Main Outcome MeasuresStudied outcomes included the rate of marginal necrosis, surgical time, postoperative posterior interosseous nerve damage and urethral complications (fistula, stenosis or necrosis).ResultsA total of 27 FRFA flap phalloplasties was performed. Anastomosis of the PIOA was needed in 15 cases. No marginal necrosis was observed in these cases. There were no cases of postoperative posterior interosseous nerve damage. There were no significant differences in urethral complications (fistula, stenosis or necrosis) between the 2 groups.Clinical ImplicationsIn selected cases where insufficient perfusion of the dorsoradial part of the flap is present, patients may benefit from arterial supercharging to prevent postoperative marginal necrosis.Strength & LimitationsStrengths include a single surgeon, thus lending continuity of skill and technique, a consecutive series, and 100% short-term follow-up. Limitations include single institution series and a limited number of patients.ConclusionArterial supercharging is effective in improving perfusion of large FRFA flaps used in phalloplasty when dorsoradial hypoperfusion is detected on an indocyanine green perfusion scan. It is a technically challenging addition to the standard technique because of the small size of the vessels, the close relationship between the PIOA and the posterior interosseous nerve, and the vulnerability of the newly constructed intra-flap anastomosis.De Wolf E, Claes K, Sommeling CE, et al.
