Purpose: We compared the efficacies of intravesical instillation of the mitomycin
(MMC), Pasteur bacillus Carmette-Guerin (B.C.G.)(PBCG) and Tice B.C.G (TBCG) in
patients with high risk superficial transitional cell carcinoma of bladder.
Materials and methods: Our study included 49 patients with the stage T1 and the
stage Ta with recurrent, grade 3, multiple or greater than 3 cm sized tumor. After
complete transurethral resection of all visible tumors, 11 out of them were treated
intravesically with 40 §· mitomycin C once a week for 8 consecutive weeks, 21 with
8¡­15¡¿106 colony-forming units (CFU) Pasteur BCG and 17 with 2¡­8¡¿
108 CFU Tice BCG once a week for 6 consecutive weeks.
Results: The mean followup periods were 51.6 months for MMC group, 33 months for
PBCG group and 17.8 months for TBCG group. The overall recurrence rates were 72.7%
for MMC group, 38% for PBCG group and 17.6% for TBCG group (p=0.014). The mean
times for recurrence were 8.1 months for MMC group, 9.7 months for PBCG group and
13.3 months for TBCG group (p=0.610). The tumor progression rates in each group were
following, 3/11 (27%) for the MMC group, 2/21 (9.5%) for the PBCG group and 1/17
(5.9%) for the TBCG group (p>0.05). The difference in recurrence free survival rates
between MMC group and PBCG group and between TBCG group and PBCG group was
not significant (p>0.05). The difference in recurrence free survival rates between MMC
group and TBCG group was significant (p=0.0012).
Conclusions: Our result showed that TBCG group was superior to the others in
recurrence rate and recurrence free survival rate, but further study including longterm
followup and various HCG instillation dosage Is needed In order to confirm the
preventive efficacy of BCG according to strain in superficial bladder tumor.
