Assuming that PR is influenced by both patient, as well  
as treatment-related events, and given that the former can-  
not be modified, the focus continues to be on optimizing  
our treatment outcomes. Unfortunately, from a systemic  
standpoint, the use of neoadjuvant chemotherapy does not  
appear to influence PR following cystectomy. The adequacy  
of surgery and extent of pelvic lymphadenectomy continue  
to be areas of active interest in mitigating PR and improving  
overall survival. Importantly, the NRG-GU001 randomized,  
phase 2 trial of postoperative adjuvant intensity modulated  
radiotherapy is poised to answer whether radiotherapy can  
reduce PR in those at-risk for its development (pT3-4pN0-2).  
See related article on page 90.  
n their study, Eapen et al have highlighted the ongoing  
and significant problem of pelvic recurrence (PR) follow-  
I
ing radical cystectomy for urothelial carcincoma of the  
1
bladder. In keeping with literature to date, PR was defined  
as recurrence of disease within soft tissues in the region of  
surgical resection or lymph node recurrence in the region  
of pelvic lymph node dissection below the level of aortic  
bifurcation. It is well-recognized that prognosis in this cohort  
of patients is uniformly poor, with median survivals ranging  
from 48 months from diagnosis despite treatment.  
Competing interests: The author declares no competing financial or personal interests.  
The patient cohort in the current study was captured using  
a survey approach involving 111 patients across 10 institu-  
tions in Canada. Overall, 11.7% had PR only, which is in  
keeping with a PR rate of 515% in contemporary cystec-  
tomy cohorts. However, if those with concomitant distant  
metastases (DM) are to be included, a total of 34.2% patients  
were assessed to have PR. This distinction is an important  
one, given that in those with DM, it is possible, and likely,  
that PR preceded DM. Unfortunately, given the size and  
nature of this study, it is not reasonable to ascertain patient  
and treatment risk factors for PR and DM.
