Bilateral internal iliac artery infusion of chemotherapeutic agents in patients with advanced bladder carcinoma, Stage D, resulted in a 50% response or greater in nine of 15 patients with a median survival, thus far, of 52 weeks. Hematuria was controlled in eight of ten patients, and pain was relieved in 12 of 15 patients. Three additional patients were treated as adjuvants after their residual tumor was removed surgically or irradiated before chemotherapy. Cis-diamminedichloroplatinum (CDDP) was infused at a dose of 80--120 mg/m2 over a 24-hour period. When CDDP failed or in the presence of impaired renal function, a combination of 5-fluorouracil (5-FU) infused intraarterially while Adriamycin and mitomycin C were delivered intravenously, salvaged two patients. Complications were tolerable, consisting of transient acute tubular necrosis in two patients, a lower extremity embolus in one, and skin reactions due to 5-FU in two patients.

In a previous study we found that an episode of acute subclinical nephrotoxicity with gentamicin (G) (but not that induced by another proximal tubular cell nephrotoxin: ferric nitrilotriacetate, FeNTA), paradoxically reduced the progression of renal function and injury in uninephrectomized rats with nephrotic glomerular disease due to Adriamycin nephropathy (AN). Here, we hypothesized that subclinical exposure to G reduces early renal cortical tubulointerstitial inflammation and NF-kappaB activation in AN. To test this hypothesis, male Wistar rats with established AN received either G (10, 40, or 80 mg/kg by daily s.c.i. for 3 days), FeNTA (1.25, 5, or 10 mg/kg by a single i.p.i.), or vehicle (n=8 per group), 13 to 15 days after disease induction. Although G and FeNTA caused acute tubular necrosis in a dose-dependant manner (day 17), only the highest doses (10 mg/kg and 80 mg/kg) produced an acute elevation in the serum creatinine. On day 33, chronic tubulointerstitial inflammation (tubular atrophy, interstitial ED-1+/CD8+ cell accumulation) and NF-kappaB activation were exacerbated only in the groups that caused functional nephrotoxicity. These data suggest that: 1) the protective effect of subclinical G nephrotoxicity in chronic AN does not involve early changes in interstitial inflammation or NF-kappaB activation; and 2) a single episode of G exposure must be accompanied by clinically apparent nephrotoxicity in order to accelerate progression in a nonuremic model of chronic glomerular disease.
