Current concepts of organ-sparing surgery in penile cancer

چکیده
The report by Palminteri et al. on penis-preserving surgery (PPS) in various benign and malignant penile lesions is interesting. The authors describe their technique of the use of the split-thickness skin graft (STSG) for neo-glans reconstruction after glansectomy, partial penectomy and in patients in whom all the glanular skin is removed and replaced by STSG. They confirm the feasibility of optimal functional outcome and oncological control in their 21 patients. The basic concepts of PPS in penile cancer involve excision of the lesion with an adequate safety margin, and taking multiple frozen-section biopsies from the base and edges [1–3]. With strict adherence to these requirements, a few millimetres of normal surrounding tissue is enough as a surgical margin. Similar to partial nephrectomy, where contemporary reports support that a much smaller safety margin than historically reported is enough for oncological control, PPS follows in the same footsteps. The techniques of PPS were first described by Bissada [1] in the 1980s and were later recommended by several authors. In the original description, tailored excision of the lesion was performed, followed by multiple deep and lateral frozen-section biopsies [1,2]. The ‘tailored’ excision means excising the lesion with a surrounding few millimetres of normal tissue as a safety margin. How deep this tailored excision depends on how deep the tumour is, with excision of underlying Buck’s fascia, tunica albuginea or corporal tissue as needed. This principle is applied irrespective of the tumour location, whether in the glans or the penile shaft. Corporeal involvement can be easily identified by careful clinical examination. Recently MRI was advocated for accurate local tumour staging and postoperative follow-up [4]. The defect is closed either by primary suturing or the application of skin grafts (partial or full thickness). Skin grafts can be harvested from the thigh or the inner side of the forearm. When using skin grafts, it is wise to take a graft larger

Primary penile cancer organ sparing treatment
INTRODUCTION Surgical treatment of penile cancer is usually associated with mutilation; alterations in self-esteem and body image; affecting sexual and urinary functions; and declined health-related quality of life. Recently, organ sparing treatment has appeared and led to limiting these complications. MATERIAL AND METHODS An extensive review of the literature concerning penile-preserving str...

OBJECTIVE The aim of this study was to present early outcome data for patients treated for penile cancer with organ-sparing reconstructive surgery at two referral centres in Sweden. MATERIAL AND METHODS Oncological, cosmetic and functional outcome and complications were analysed retrospectively during the period 2011-2013. Twelve patients with non-invasive penile cancer were treated with glan...

Penile cancer is a rare malignancy in most developed nations but its management can have significant anatomical, functional and psychological effects in patients. Whilst total penectomy used to be widely practiced, it is associated with significant psychological consequences pertaining to body image and masculinity, with loss of sexual function and the ability to void upright. Recent advances i...
متن کاملConservative surgery for the treatment of penile carcinoma
The rationale for organ preserving surgery in the treatment of squamous cell carcinoma (SCCA) of the penis is based on three key concepts. 1. About 80% of penile carcinomas occur distally, involving the glans and/or prepuce and thus are potentially amenable to organ preserving surgery. 2. Patients with penile carcinomas stages Tis, Ta, T1; grades 1 and 2 are at low risk for local progression an...
متن کاملOutcomes for Organ-Preserving Surgery for Penile Cancer
AIM Squamous cell carcinoma of the penis (PC) has traditionally been treated with partial penectomy with a 2-cm margin. More conservative resection margins have been reported to have no effect on oncologic control, but there is no consensus in the literature regarding functional outcomes after organ-preserving surgery for PC. METHODS Six patients meeting inclusion criteria were retrospectivel...
