International case series of metastasis to penis

Penile metastases are rare, with about 400 reported via case reports or small series. Under such circumstances coherent data about their behaviour may not be possible given vagaries of publication. For instance, one published meta‐analysis has proposed that malignant priapism contributes to worse survival, but this may be due to selection bias in published reports. We sought to evaluate clinical characteristics associated with survival in an international cohort of patients with metastases to the penis treated in major genitourinary cancer programmes.
