Penile cancer, while relatively rare in the western world, remains a disease with severe morbidity and mortality, not to mention significant psychological ramifications. Furthermore, the disease is observed with dramatically increased incidence in other parts of the world. A review of the literature has shown that the overwhelming majority of penile cancers are in situ or invasive squamous cell carcinomas, including a well-differentiated variant, verrucous carcinoma. Important predisposing factors are lack of circumcision, human papillomavirus infections, and penile lichen sclerosus, although other factors have occasionally been reported as well. Prevention, careful monitoring of patients at risk, and early diagnosis are essential to reduce the incidence of penile carcinoma and to provide a definitive cure. Public health measures, such as prophylactic use of circumcision, have proved successful but are controversial. Also, no standard therapeutic guidelines as to the best treatment strategy according to different stages, including efficacy of conservative nonsurgical modalities and indications for lymph nodal dissection, are available so far. It is common opinion that penile cancer is an emerging problem that deserves further investigations, and physicians, especially dermatologists, should be aware of this issue.
At the completion of this learning activity, participants should be familiar with penile carcinoma, its risk factors, its clinical and histologic presentation, and the treatments currently available for its management.
阴茎癌在西方世界相对罕见,但仍然是一种具有严重发病率和死亡率的疾病,更不用说其显著的心理影响了。此外,在世界其他地区,该疾病的发病率显著上升。文献综述表明,绝大多数阴茎癌是原位或浸润性鳞状细胞癌,包括一种高分化变体疣状癌。重要的诱发因素包括未行包皮环切术、人乳头瘤病毒感染和阴茎硬化性苔藓,不过偶尔也有其他因素的报道。预防、对高危患者的密切监测以及早期诊断对于降低阴茎癌的发病率和实现根治至关重要。诸如预防性包皮环切术等公共卫生措施已被证明是成功的,但存在争议。此外,目前尚无关于根据不同阶段制定最佳治疗策略的标准治疗指南,包括保守非手术方式的疗效和淋巴结清扫的指征。普遍认为阴茎癌是一个值得进一步研究的新出现问题,医生,尤其是皮肤科医生,应该意识到这个问题。
在完成本学习活动后,参与者应熟悉阴茎癌、其危险因素、临床和组织学表现以及目前可用于其治疗的方法。
