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).

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 4‒8 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 5‒15% 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.
