Primary urethral cancer in males is a rare entity with only approximately 800 cases described, which is why it is difficult to formulate evidence-based guidelines for treatment. For tumors in the pT2 stage with a localization distal to the membranous urethra, a penis-preserving operation can be carried out.
In the period from November 2006 to February 2014 a total of 4 patients with primary urethral cancer underwent a penis-preserving urethral resection. The tumor characteristics and treatment results were collated retrospectively.
Of the four patients one had a transitional cell carcinoma of the mid-penile urethra in stage pT2 G2. In two out of the four patients a squamous cell carcinoma (PEC) was present in the mid-penile urethra in stages pT2 G2 and pT2 G3, respectively, with concomitant carcinoma in situ (CIS). The fourth patient had a PEC of the fossa terminalis in stage pT2 G2. Initially all patients underwent a penis-preserving resection. In one case, despite an initial R0 resection a local recurrence occurred and a complete penectomy was performed. Irradiation and lymphadenectomy were not carried out. At a mean follow-up of 37 months all patients are currently in complete remission.
Primary penile urethral cancer can be treated by a penis-preserving operation. Close follow-up is essential because recurrence can arise despite an initial R0 resection.
男性原发性尿道癌是一种罕见疾病,仅有约800例病例报道,这就是为何难以制定基于证据的治疗指南。对于处于pT2期且位于膜部尿道远端的肿瘤,可实施保留阴茎手术。
在2006年11月至2014年2月期间,共有4例原发性尿道癌患者接受了保留阴茎的尿道切除术。对肿瘤特征及治疗结果进行回顾性整理。
4例患者中,1例为阴茎中段尿道移行细胞癌,处于pT2 G2期。4例患者中有2例分别在阴茎中段尿道存在鳞状细胞癌(PEC),处于pT2 G2期和pT2 G3期,伴有原位癌(CIS)。第4例患者为尿道舟状窝PEC,处于pT2 G2期。最初所有患者均接受了保留阴茎的切除术。1例患者尽管初始为R0切除,但仍发生局部复发,随后进行了阴茎全切术。未进行放疗及淋巴结清扫术。平均随访37个月时,所有患者目前均处于完全缓解状态。
原发性阴茎尿道癌可通过保留阴茎手术进行治疗。密切随访至关重要,因为尽管初始为R0切除,仍可能出现复发。
