Every week the Editor-in-Chief selects the Article of the Week from the current issue of BJUI. The abstract is reproduced below and you can click on the button to read the full article, which is freely available to all readers for at least 30 days from the time of this post.
In addition to the article itself, there is an accompanying editorial written by prominent members of the urological community. This blog is intended to provoke comment and discussion and we invite you to use the comment tools at the bottom of each post to join the conversation.
If you only have time to read one article this week, it should be this one.

• To assess the prognostic impact of time to recurrence (TTR) on cancer-specific survival (CSS) after recurrence in patients with renal cell carcinoma (RCC) undergoing radical nephrectomy or nephron-sparing surgery.
• To analyse differences in clinical and histopathological criteria between patients with early and late recurrence.
PATIENTS AND METHODS
• Of 13 107 patients with RCC from an international multicentre database, 1712 patients developed recurrence in the follow-up (FU), at a median (interquartile range) of 50.1 (25–106) months.
• In all, 1402 patients had recurrence at ≤5 years (Group A) and 310 patients beyond this time (Group B).
• Differences in clinical and histopathological variables between patients with early and late recurrence were analysed.
• The influence of TTR and further variables on CSS after recurrence was assessed by Cox regression analysis.
• Male gender, advanced age, tumour diameter and stage, Fuhrman grade 3–4, lymphovascular invasion (LVI), and pN + stage were significantly more frequent in patients with early recurrence, who had a significantly reduced 3-year CSS of 30% compared with patients in Group B (41%; P = 0.001).
• Age, gender, tumour histology, pT stage, and continuous TTR (hazard ratio 0.99, P = 0.006; monthly interval) independently predicted CSS.
• By inclusion of dichotomised TTR in the multivariable model, a significant influence of this variable on CSS was present until 48 months after surgery, but not beyond this time.
• Advanced age, male gender, larger tumour diameters, LVI, Fuhrman grade 3–4, pN + stage, and advanced tumour stages are associated with early recurrence.
• Up to 4 years from surgery, a shorter TTR independently predicts a reduced CSS after recurrence.
