In a sample of 306 patients with superficial bladder tumors (Ta, Tl), 48 were affected by associated carcinoma in situ (TIS). We included 40 of them in a random program with Mitomycin C or Adriamycin, administered endovesically. We found that those patients with associated TIS whose progression rate had increased to 37.1% compared to 8.8% in the original series (p less than 0.01), had a worse prognosis. Besides, 10 of them required radical cystectomy. With this chemotherapy program, we achieved a high rate of complete response (70%), but its duration was limited by a recurrence rate of 42.9%, with a time free of disease of 26.2 months. In the whole group, the survival rate free of disease was 77.5%, with an average follow-up of 37.3 months. On the other hand, we found extravesical recurrences not only in the prostatic urethra (13; 32.5%) but also at the end of the ureter (3; 7.5%).

Combination chemotherapy with methotrexate, etoposide, adriamycin and cisplatin (M-EAP regimen) was administered to 4 patients with advanced epithelial cancer of the urinary tract (Methotrexate 30 mg/M2 day 1, 15 and 22; Etoposide 100 mg/M2 day 1, 2, 15 and 22; Adriamycin 30 mg/M2 day 2; Cisplatin 70 mg/M2 day 2, every 4 weeks). In an attempt to improve the anti-cancer effect of the M-VAC regimen, etoposide was substituted for vinblastine. This series comprised 3 males and 1 female ranging in age from 54 to 68 years (mean age: 63), with a performance status of 1 to 2. The site of the primary lesion was bladder in 3, and left ureter in 1. The clinical response was assessed in 3 of the 4 patients: one achieved complete response and two had partial response. Two of the four died of disease 5 months after chemotherapy. Two of them have been alive for 10 and 8 months with no evidence of disease after chemotherapy. Toxicity included moderate or severe myelosuppression in two patients, and mild to moderate anorexia, vomiting, alopecia, and hiccups in all patients. These preliminary results suggest that the M-EAP regimen is effective against advanced epithelial carcinoma of the urinary tract. However, myelosuppression was a dose-limiting factor.

The body consists of systems of conductive pathways for ionic flow of current induced by metabolic or injury potentials among tissues and cells. In vivo electrophoresis in biologically closed electric circuits (BCEC) are coupled to the mechanical transports of blood and lymph. Connections also exist with conductive media such as cerebrospinal fluid, bile, and urine. Artificial induction of current was applied over the kidneys in order to study modification of kidney function. It is thought that studies of this kind will increase our understanding of kidney function from a new angle of view and possibly add new therapeutic possibilities. In anesthetized pigs, one kidney was made anodic (electropositive) and the other cathodic (electronegative). Current was applied between electrodes in each ureter. Intravascularly injected, electronegatively charged aminotrizoate and ioxaglate were excreted mainly by the anodic kidney. Nonionic iohexol was urographically excreted by both kidneys. Excretion of electropositively charged Adriamycin by the cathodic kidney was identified macroscopically and by chemical analysis. Functional effects on the kidneys can be induced electrophoretically without causing injury.

To evaluate the relative efficacy of cisplatin, cyclophosphamide, and Adriamycin (doxorubicin; Adria Laboratories, Columbus, OH) (CISCA) versus methotrexate, vinblastine, Adriamycin, and cisplatin (MVAC), a prospective randomized trial was performed in patients with advanced metastatic urothelial tumors. Patients were stratified by histologic disease type and degree of tumor dissemination. Equal distribution of the clinical characteristics was achieved. One hundred ten patients with metastatic disease of the urinary tract (86 bladder, 16 renal pelvis, seven ureter, one prostatic urethra) met eligibility criteria and were enrolled on study. These represented 82% of the total patients seen during the study period in the Section of Genitourinary Oncology who met the eligibility criteria. The combined complete and partial response rate was significantly higher for patients treated with MVAC than for those treated with CISCA (65% v 46%; P less than .05). The survival duration of MVAC-treated patients was significantly longer than that of CISCA-treated patients (mean, 62.6 weeks; median, 48.3; range, 5.0+ to 162.3+ v mean, 40.4 weeks; median, 36.1; range, 7+ to 147.1+). We conclude that MVAC chemotherapy is superior to CISCA chemotherapy, achieving a higher response rate and a longer survival for equivalent patients with metastatic urothelial tumors.

Thirty-three patients with advanced transitional cell carcinoma of the urinary tract (23 bladder cases, 8 ureter cases, and 2 renal pelvis cases) were treated by three-drug combination chemotherapy using two protocols (protocol I: Adriamycin 50 mg/m2, cyclophosphamide 500 mg/m2, and 5-fluorouracil 500 mg/m2, protocol II: Adriamycin 50 mg/m2, cyclophosphamide 500 mg/m2, and cis-platinum 50 mg/m2). Protocol I induced responses in three of 19 patients (16%), (1 complete response, 2 partial responses), and protocol II (I complete response, 4 partial responses) in five of 14 patients (36%). The overall response rate was 24%. The duration of response was relatively short (median duration 5.1 months). The combination therapy was relatively well tolerated except in three patients, including two mortalities. In our study, three-drug combination chemotherapy with Adriamycin, especially that including cis-platinum, was effective against transitional cell carcinoma of the urinary tract, but the results were not completely satisfactory.
