Although penile carcinoma is a rare malignancy, there is still an unmet need to identify prognostic factors associated with poor survival. In this study, we utilized demographic and clinical information to identify the most informative variables associated with overall survival in patients with penile cancer. From a full model including all covariates found to be statistically significant in univariable analyses, we identified a parsimonious reduced model containing tumor site (penis glans: hazard ratio [HR] = 0.48; 95% CI: 0.28-0.85 and penis not otherwise specified: HR = 0.45; 95% CI: 0.25-0.84), undetermined tumor differentiation (HR = 0.48; 95% CI: 0.27-0.86), and TNM stage III/IV (HR = 2.83; 95% CI: 1.68-4.75). When all of the covariates from the full model were subjected to classification and regression tree analysis, we identified 6 novel risk groups. Of particular interest, we found marriage was associated with substantial improvement in survival among men with the same stage and disease site. Specifically, among single/widowed/divorced men with TNM stage 0-II and prepuce/penis corpus/overlapping lesions had worse survival (5-year survival = 18.2%) versus married men (5-year survival = 62.5%). Since marital status is linked to social support, these findings warrant a deeper investigation into the relationships between disease prognosis and social support in patients with penile carcinoma.

阴茎癌患者的新型预后模型。

尽管阴茎癌是一种罕见的恶性肿瘤,但仍缺乏确定与不良生存相关的预后因素的需求。在这项研究中,我们利用人口统计学和临床​​信息来识别与阴茎癌患者总体生存相关的最有用的变量。从包括所有在单变量分析中具有统计学意义的协变量的完整模型中,我们确定了一个包含肿瘤部位的简约简化模型(阴茎龟头:危险比[HR] = 0.48; 95%CI:0.28-0.85,未另作说明的阴茎: HR = 0.45; 95%CI:0.25-0.84),未确定的肿瘤分化程度(HR = 0.48; 95%CI:0.27-0.86)和TNM III / IV期(HR = 2.83; 95%CI:1.68-4.75)。对来自完整模型的所有协变量进行分类和回归树分析时,我们确定了6个新的风险组。特别令人感兴趣的是,我们发现婚姻与处于相同阶段和疾病部位的男性的生存率显着提高有关。具体而言,在TNM为0-II期的单身/丧偶/离异的男性和包皮过长的阴茎/阴茎/重叠的病变中,已婚男性的生存较差(5年生存= 18.2%),而已婚男性(5年生存= 62.5%)。由于婚姻状况与社会支持有关,因此这些发现值得深入研究阴茎癌患者的疾病预后与社会支持之间的关系。在TNM 0-II期单身/丧偶/离婚男性和包皮过长/阴茎体/重叠病变中,成年男性的生存期较差(5年生存率= 18.2%),而已婚男性(5年生存期= 62.5%)。由于婚姻状况与社会支持相关,因此这些发现值得深入研究阴茎癌患者的疾病预后与社会支持之间的关系。在TNM 0-II期单身/丧偶/离婚男性和包皮过长/阴茎体/重叠病变中,成年男性的生存期较差(5年生存率= 18.2%),而已婚男性(5年生存期= 62.5%)。由于婚姻状况与社会支持有关,因此这些发现值得深入研究阴茎癌患者的疾病预后与社会支持之间的关系。
