Results with primary retroperitoneal lymphadenectomy in 464 patients with clinical stage A nonseminomatous germ cell testis cancer (1965 to 1989) were reviewed. The false-negative staging error by clinical methods remains at 30%. The relapse rate in pathological stage A cancer patients was 11% (37 of 323), with 2 deaths. For pathological stage B disease 64% of the patients were cured by retroperitoneal lymphadenectomy alone. With modern adjuvant chemotherapy no stage B tumor relapsed since 1979 and the survival rate was 100%. For all 25 years (464 patients) the relapse rate was 14% and the survival rate was 98.9% (3 cancer and 2 noncancer deaths). Because these results are based on preoperative clinical staging, they are directly comparable with series using radiotherapy or surveillance.

Cecoileal reservoirs were created in 29 patients. Tunneled ureteral implantations along the tenia of the cecum provided the antireflux mechanism. Plication or tapering of the terminal ileal segment along with the ileocecal valve provided the continence mechanism. The tubular configuration of the cecum was disrupted with either an ileal or sigmoid patch, or it was re-configured in a Heineke-Mikulicz type of closure to avoid bolus (unit) contractions. Short-term followup examination with excretory urography showed no upper tract obstruction. X-rays of the pouch showed no reflux and interviews revealed satisfactory continence in 93 per cent of the patients.

A total of 80 patients with stage B3 or B2/C germ cell testis tumors underwent computerized tomography before and after chemotherapy. The volume and computerized tomographic density of metastatic retroperitoneal tumor were measured on all scans. The patients then underwent full bilateral retroperitoneal lymphadenectomy. The change in volume and density of retroperitoneal disease was correlated with the histological type of the primary testis tumor and with the histological findings at retroperitoneal lymphadenectomy. In all 15 patients (100 per cent) without teratomatous elements in the original tumor and who had a greater than 90 per cent decrease in the volume of retroperitoneal masses as a response to systemic chemotherapy no teratoma or active cancer was found in the surgical specimen. In contrast, 7 of 9 patients (78 per cent) with teratomatous elements in the original specimen had either teratoma or carcinoma in the retroperitoneal lymphadenectomy specimens despite having a greater than 90 per cent decrease in tumor volume. This difference was significant (p less than 0.05). These data suggest that patients with no teratomatous elements in the original specimen and a greater than 90 per cent decrease in the volume of retroperitoneal masses in response to chemotherapy can be observed carefully for signs of recurrence rather than undergoing post-chemotherapy retroperitoneal lymphadenectomy.

For patients with no prior intravesical therapy adjuvant intravesical chemotherapy or immunotherapy is a treatment option after endoscopic removal of low grade Ta bladder cancers. Intravesical instillation of bacillus Calmette-Guerin or mitomycin C is recommended for carcinoma in situ, and after endoscopic removal of T1 and high grade Ta tumors.
