Page Background

prostatic urethral involvement in the RC specimen was 71%

and 100%, respectively, with an overall accuracy of 89%.

However, this study did not compare biopsy results with

frozen or permanent section analysis of the distal urethral

margin, which is the key clinical question. Futhermore,

prostatic urethral biopsy failed to detect prostatic stromal

invasion of the urothelial carcinoma in 11 of 15 patients

( 73%). Apart from this study, it should be emphasized that

a prostatic cold cup urethral biopsy results in lower

accuracy rates compared with a transurethral loop biopsy

for the detection of prostatic urothelial malignancy

[40]

.

Given the high rates of concomitant prostatic urethral

malignancy (37–38%) and low rates of distal urethral

malignancy ( 6–9%) at the level of urethral transection

[8,34]

, the routine use of preoperative prostatic urethral

biopsy is likely to unnecessarily exclude a considerable

number of patients who desire OBS as their preferred type

of diversion. Furthermore, as there is a relatively low

positive predictive value of prostatic urethral biopsy for

predicting disease at the urethral margin at RC, collective

data suggest that a FSA of the urethral margin should be

performed for men scheduled for OBS

[41]

. Therefore, in the

authors’ opinion a positive transurethral biopsy before

cystectomy is not a reason to exclude a patient a priori from

undergoing an orthotopic diversion.

What are treatment options and outcomes of secondary

urothelial tumors after RC?

3.4.1.

Treatment of secondary upper tract tumors

Table 1

provides a comprehensive overview on the available

data on treatment and outcomes of secondary upper

recurrences. Thirteen studies reported explicitly on the

location of recurrences (urothelial and/or local [retro-

peritoneum/pelvic] and/or distant) during staging of

238 patients with secondary upper tract recurrence. Of

these, 210 (88.2%) patients had urothelial recurrence

without evidence of local/pelvic or distant disease at the

time of diagnosis. Concomitant urothelial and distant

recurrence was present in 21 (8.8%) patients and concomi-

tant urothelial and pelvic recurrence in seven (2.9%).

Modality of treatment of upper tract recurrence was

reported in 14 studies in a total of 263 patients. Of these

patients, 160 (60.4%) were treated with radical nephro-

ureterectomy, which was done with preoperative or

postoperative

[80_TD$DIFF]

systemic chemotherapy in nine cases (3.4%).

Three (1.1%) patients were treated with segmental ureter-

ectomy, while endoscopic surgery was utilized in 21 (7.9%)

patients. Systemic chemotherapy alone was administered in

17 (6.4%) patients and topical chemotherapy or immuno-

therapy with Bacille Calmette-Guerin (BCG) in nine (3.4%).

In 53 (33.1%) patients some kind of surgical treatment

was performed but not further defined in the respective

publications.

Survival outcomes after treatment of secondary upper

tract recurrence were reported in 13 studies including a total

of 464 patients. Survival data with regard to duration of

follow-up was available in nine studies with a median

follow-up of 88 mo (range: 26–126). Overall survival status

with information on disease status was reported in

363 patients. Of these, 259 (55.2%) died of disease and 58

(12.4%) died of other causes. Thirty-three (7.0%) patients

were living without evidence of disease and 13 were alive

with disease (2.8%). Overall survival status without infor-

mation on disease status was additionally reported in

101 patients. Of these, 58 (12.4%) were reported to be alive

and 43 (9.2%) to have died.

Altogether, these findings suggest that although most

recurrences were detected in nonmetastatic stages, out-

comes were poor possibly due to the presence of micro-

metastatic disease at the time of surgery. These data

reinforce our suggestion for a risk-adapted approach to

identify recurrences at the earliest possible to stage in order

to treat in a curative intent. However, there is some

evidence supporting renal-sparing approaches for the

treatment of upper tract recurrences with low-grade,

low-volume disease

[42]

. These include endoscopic ablation

of tumor or open kidney-sparing surgery with reconstruc-

tion of the upper tract

[1]

. Similar to patients with urethral

CIS, those with CIS of the upper tract can be managed

effectively with antegrade instillation of BCG via a

percutaneous nephrostomy

[43]

.

Treatment of urethral recurrences

Table 2

provides a comprehensive overview of the available

data on recurrence patterns, treatment, and outcomes of

patients with secondary urethral recurrences. Eight studies

reported on recurrence patterns in 51 patients with

secondary urethral recurrences after RC. Urothelial recur-

rence was identified in the

[81_TD$DIFF]

urethra only in 34 (66.7%) of the

patients. Urethral plus distant recurrences were present in

11 (21.6%). Concomitant urethral and pelvic recurrences

were noted in four (7.8%) patients and concomitant

urethral, pelvic, and distant recurrences in two (3.9%).

The modality of treatment of urethral recurrence was

reported in 10 studies including 223 patients. Of these

patients, 153 (66.2%) were treated with partial or complete

urethrectomy. Systemic chemotherapy and/or radiotherapy

were utilized in 34 (14.7%) patients, of whom eight

underwent also surgery. Topical chemotherapy or immuno-

therapy with BCG was administered in 18 (7.8%) patients.

Transurethral resection was conducted alone in three

patients (1.3%). In 15 (6.5%) patients some kind of surgery

was performed but not further defined in the respective

publications.

Survival outcomes after treatment of urethral recurrence

were reported in nine studies including a total of

202 patients with a median follow-up of 97 mo (range:

29–155). Overall survival status with information on

disease status was reported in 162 patients. Of these, 87

(43.1%) patients died of disease and 55 (27.2%) died of other

causes. Nineteen (9.4%) patients were living without

evidence of disease and one was alive with disease

(0.5%). Twenty-four (11.9%) patients were reported to be

alive and 16 (7.9%) to have died with no further information

on disease status at the time of analysis.

As for secondary upper tract recurrences, outcomes after

treatment of urethral recurrence are poor despite use of
