Complications of bacillus Calmette-Guerin immunotherapy in 1,278 patients with bladder cancer.

Our series of 195 patients, plus 134 reported on in the literature and 949 reviewed by various physicians provide 1,278 patients for review of bacillus Calmette-Guerin therapy complications. Cystitis occurred in 91 per cent of the patients. Complications identified included fever more than 103F in 50 patients (3.9 per cent), granulomatous prostatitis in 17 (1.3 per cent), bacillus Calmette-Guerin pneumonitis or hepatitis in 12 (0.9 per cent), arthritis or arthralgia in 6 (0.5 per cent), hematuria requiring catheterization or transfusion in 6 (0.5 per cent), skin rash in 5 (0.4 per cent), skin abscess in 5 (0.4 per cent), ureteral obstruction in 4 (0.3 per cent), epididymo-orchitis in 2 (0.2 per cent), bladder contracture in 2 (0.2 per cent), hypotension in 1 (0.1 per cent) and cytopenia in 1 (0.1 per cent). Most of the severe irritative side effects and subsequent systemic complications can be prevented with prophylactic isoniazid given for 3 days, beginning the morning of treatment. Patients with life-threatening systemic bacillus Calmette-Guerin infection or anaphylaxis should receive 500 mg. cycloserine twice daily for 3 days in addition to combination antituberculous therapy because the rapid action of this drug may be life-saving. Direct intralesional bacillus Calmette-Guerin immunotherapy can produce sepsis and death, and should be avoided but intravesical bacillus Calmette-Guerin generally is well tolerated and has produced no complication in more than 95 per cent of the patients treated.

HLA-A, B and DR in Caucasians with transitional cell carcinoma of the bladder.

When HLA-A, B and DR antigens in Caucasian patients with transitional cell carcinoma of the urinary bladder were compared with controls, no significant alterations in antigen frequencies were found.

Bladder cancer immunotherapy.

A randomized controlled prospective evaluation of intravesical and percutaneous bacillus Calmette-Guerin immunotherapy was done in 57 patients with transitional cell carcinoma of the bladder. In addition, 9 patients at high risk for tumor recurrence were treated with bacillus Calmette-Guerin produced a self-limited cystitis and 1 complication (hydronephrosis) of immunotherapy was observed. Of the 57 randomized patients 54 were followed for 3 to 30 months. Tumor recurrence was documented in 13 of 26 controls (50 per cent) and only 6 of 28 patients (21 per cent) treated with bacillus Calmette-Guerin (p equals 0.027, chi-square). The interval free of disease was prolonged significantly with bacillus Calmette-Guerin treatment (p equals 0.014, generalized Wilcoxon test). Importantly, a simple purified protein derivative skin test distinguished those patients who responded to bacillus Calmette-Guerin immunotherapy from those who did not. Only 1 of 17 treated patients (6 per cent) whose purified protein derivative test converted from negative to positive had tumor recurrence compared to 5 recurrences (38 per cent) among the 13 patients whose test remained negative or had been positive before treatment (p equals 0.022, chi-square). Bacillus Calmette-Guerin was given to 10 patients with stage B transitional cell carcinoma who were not candidates for cystectomy and 7 are free of disease. Of 5 patients with carcinoma in situ 3 remain free of tumor after bacillus Calmette-Guerin treatment and 5 of 6 who had multiple recurrences after intravesical chemotherapy responded favorably to bacillus Calmette-Guerin immunotherapy.

BCG immunotherapy of bladder cancer: inhibition of tumor recurrence and associated immune responses.

Fifty-one patients with confirmed bladder cancer have enrolled in a prospective evaluation of BCG immunotherapy. Following resection of existing tumors, patients were stratified according to tumor grade and number of previous recurrences and randomly assigned to control or BCG treatment groups. Immunotherapy consisted of six weekly administrations of Pasteur strain BCG using 120 mg intravesically and 5 mg percutaneously. Immunotherapy side effects were minimal and no patient required postponement of BCG treatments. Eleven control (46%) compared with five (22%) BCG-treated patients had tumor recurrence (P = 0.078, chi 2). Prolongation of the disease-free interval with BCG treatment was significantly at the P = 0.016 level by Wilcoxon analysis. Four control and two BCG-treated patients had multiple recurrences. Comparing total episodes of recurrence, nineteen of 79 (24%) control and eight of 85 (7%) BCG group cystoscopic examinations revealed tumor (P = 0.006, chi 2). Immunologic correlates of response to immunotherapy were not statistically significant since only five BCG-treated patients had tumor recurrence. However, four of these five patients evidenced impaired LIF response to PPD at the time of tumor recurrence, and impairment of skin test reactivity and BCG humoral antibody response were more commonly seen in this subgroup of patients.

Bacillus Calmette-Guerin immunotherapy of superficial bladder cancer.

Thirty-seven patients were enrolled in a randomized prospective study to compare standard surgical therapy for superficial bladder cancer to standard therapy plus bacillus Calmette-Guerin (BCG). Side effects of BCG have been tolerated well and include dysuria in 95 per cent of the patients, urinary frequency in 83 per cent, hematuria in 39 per cent, fever in 22 per cent and nausea in 22 per cent. Of 19 control patients 8 (42 per cent) had recurrent tumors in the followup period, compared to 3 of 18 patients (17 per cent) treated with BCG. One patient treated wih BCG had 2 recurrences, yielding a recurrence rate of 22 per cent in the group receiving BCG compared to 42 per cent in controls. When the incidence of recurrent tumors in matched intervals before and after entry into the protocol is compared, no change in the rate of tumor recurrence (p equals 0.726 chi-square) occurred in controls, whereas tumor recurrences were reduced significantly in the group treated with BCG (p equals 0.010 chi-square). The reduction in tumor recurrence in patients treated with BCG compared to controls is statistically significant (p equals 0.029 chi-square). Of 4 patients who presented with new bladder tumors remain free of tumor after BCG therapy, while 2 of 5 comparable control patients developed recurrent tumors. Intravesical and percutaneous BCG immunotherapy appears to decrease the rate of tumor recurrence in patients followed for 1 year.
