Abstract

A comprehensive literature study was conducted to evaluate the levels of evidence (LEs) in publications on the diagnosis and staging of penile cancer. Recommendations from the available evidence were formulated and discussed by the full panel of the International Consultation on Penile Cancer in November 2008. The final grades of recommendation (GRs) were assigned according to the LEs of the relevant publications. The following consensus recommendations were accepted: physical examination of the primary penile lesion is mandatory, evaluating the morphologic and physical characteristics of the lesion (GR A). Evaluation of the primary lesion with ultrasonography is of limited value for local tumor staging (GR C); however, evaluation of the primary tumor with magnetic resonance (MRI) imaging during artificial erection induced by intracavernosal injection of prostaglandin might be more useful (GR B). Histologic or cytologic diagnosis of the primary lesion is mandatory (GR A). For accurate histologic grading and staging, a resected specimen is preferable to a biopsy specimen alone (GR B). Penile cancer should be staged according to the TNM system; however, the 1987/2002 TNM staging system requires revision using data from larger patient cohorts to validate the recently proposed modifications (GR B). The histopathology report should provide information on all prognostic parameters, including the tumor size, histologic type, grade, growth pattern, depth of invasion, tumor thickness, resection margins, and lymphovascular and perineural invasion (GR B). Physical examination of the inguinal and pelvic areas to assess the lymph nodes is mandatory (GR B). Ultrasound-guided fine needle aspiration cytology is indicated for both palpable and nonpalpable inguinal nodes. If the findings confirm lymph node metastasis (LNM), complete inguinal lymph node dissection is indicated (GR B). In patients with nonpalpable inguinal nodes, if the ultrasound-guided fine needle aspiration cytology findings are negative for tumor, dynamic sentinel node biopsy can be performed if the equipment and technical expertise are available (GR C). In patients at high risk of inguinal LNM according to the available guidelines and nomograms, surgical staging can be performed by complete, bilateral inguinal lymph node dissection, which might also be curative (GR B). In patients at intermediate risk of LNM, sentinel node biopsy or modified (limited) inguinal lymph node dissection might be performed (GR B). In patients with nonpalpable inguinal nodes, imaging with computed tomography (CT) or MRI is not indicated, because they are not useful in detecting small-volume LNM. Also, it is very unlikely that large-volume LNM (detectable by CT/MRI) would be present in the pelvic nodes (GR B). In patients with confirmed inguinal LNM, CT of the pelvis is indicated to detect iliac LNMs (GR B). Abdominal CT and chest radiography are advisable if the pelvic CT findings are positive (GR B).

摘要

进行了全面的文献研究,以评估阴茎癌诊断和分期相关出版物中的证据水平(LE)。根据 2008 年 11 月国际阴茎癌咨询会议全体专家小组的建议,制定并讨论了相关推荐意见。最终推荐等级(GR)是根据相关出版物的 LE 确定的。以下共识推荐意见被接受:必须对原发性阴茎病变进行体格检查,评估病变的形态和物理特征(GR A)。超声检查评估局部肿瘤分期的价值有限(GR C);然而,通过在阴茎海绵体内注射前列腺素诱导勃起时对原发性肿瘤进行磁共振(MRI)成像可能更有用(GR B)。必须对原发性病变进行组织学或细胞学诊断(GR A)。为了准确的组织学分级和分期,建议使用切除标本,而不是单独的活检标本(GR B)。阴茎癌应根据 TNM 系统分期;然而,1987/2002 年 TNM 分期系统需要使用更大的患者队列数据进行修订,以验证最近提出的修改(GR B)。组织病理学报告应提供所有预后参数的信息,包括肿瘤大小、组织类型、分级、生长模式、浸润深度、肿瘤厚度、切缘以及血管淋巴管和神经周围侵犯(GR B)。必须对腹股沟和盆腔区域进行体格检查以评估淋巴结(GR B)。超声引导下细针抽吸细胞学检查适用于可触及和不可触及的腹股沟淋巴结。如果发现证实有淋巴结转移(LNM),则表明需要进行完整的腹股沟淋巴结清扫(GR B)。对于不可触及的腹股沟淋巴结,如果超声引导下细针抽吸细胞学检查结果未发现肿瘤,则如果具备设备和技术专业知识,则可以进行动态前哨淋巴结活检(GR C)。根据现有指南和列线图,对于腹股沟淋巴结转移风险高的患者,可以进行完全的双侧腹股沟淋巴结清扫术,这也可能是一种治疗方法(GR B)。对于腹股沟淋巴结转移风险中等的患者,可以进行前哨淋巴结活检或改良(有限)腹股沟淋巴结清扫术(GR B)。对于不可触及的腹股沟淋巴结,不建议进行 CT 或 MRI 成像,因为它们在检测小体积 LNM 方面没有帮助。此外,盆腔淋巴结中也极不可能存在大体积 LNM(CT/MRI 可检测到)(GR B)。对于已确诊的腹股沟淋巴结转移患者,建议进行骨盆 CT 以检测髂淋巴结转移(GR B)。如果盆腔 CT 结果阳性,建议进行腹部 CT 和胸部 X 线摄影(GR B)。
