Oncological outcome after radical cystectomy and orthotopic bladder substitution in women

Aim

The pathological outcome after radical cystectomy and orthotopic bladder substitution in women and the possibility of genital sparing are studied in a prospective way.

Methods

Between January 1995 and June 2003, 180 women with bladder cancer (mean age 50.6 years) underwent orthotopic neobladder reconstruction. Histopathologic assessment of the cystectomy specimens was performed. Involvement of the internal genitalia by primary or secondary cancer was evaluated by preoperative CT or MRI. Histopathological evaluation of these organs was made in the cystectomy specimens.

Results

Mean follow-up was 57 months. At follow-up, isolated urethral recurrence developed in two patients. Local pelvic recurrence developed in 30 patients, distant metastasis in 14 and both in nine. Uterine infiltration, which was suspected by preoperative CT, was confirmed by definitive histopathology after radical cystectomy in only two cases; otherwise there were no primary or secondary malignancies of the internal genitalia. Isolated recurrence of bladder cancer in the vaginal remnant during follow-up after cystectomy was not noted in any woman.

Conclusions

The rate of urethral recurrence and oncological failure after orthotopic bladder substitution in women is low and acceptable and thus justifies the continued performance of this type of diversion. Proper selection of cases is mandatory. In women with absence of malignant involvement of the internal genitalia on preoperative imaging, the risk of secondary malignant involvement of these organs in cystectomy specimens is very low. Therefore, preservation of the uninvolved gynecologic organs during radical cystectomy in premenopausal women with unifocal, organ-confined tumor above the bladder base, is justified.
