Seventeen-year follow-up of the prospective randomized Nordic CIS study: BCG monotherapy versus alternating therapy with mitomycin C and BCG in patients with carcinoma in situ of the urinary bladder.

Objective: The aim of this study was to compare the long-term efficacy of BCG monotherapy to alternating therapy of mitomycin C (MMC) and BCG in patients with carcinoma in situ (CIS).

Materials And Methods: Between 1992 and 1997, 321 patients with CIS were randomized from Finland, Norway and Sweden in a prospective multicenter trial into two treatment groups. The alternating therapy comprised six weekly instillations of MMC 40 mg followed by 10 instillations of BCG (Connaught 120 mg) or MMC alternating monthly for 1 year.

Bacillus Calmette-Guérin is superior to a combination of epirubicin and interferon-alpha2b in the intravesical treatment of patients with stage T1 urinary bladder cancer. A prospective, randomized, Nordic study.

Background: Bacillus Calmette-Guérin (BCG) instillation is regarded as the most effective bladder-sparing treatment for patients with high-grade T1 tumours and carcinoma in situ (CIS). The major problem with this therapy is the side-effects, making maintenance therapy difficult, even impossible, in a proportion of patients. Thus, alternative schedules and drugs have been proposed.

Results of second-look resection after primary resection of T1 tumour of the urinary bladder.

Objective: To study residual tumours at second-look resection in patients resected 4-8 weeks earlier for T1 tumours of the urinary bladder.

Material And Methods: All patients randomized in the ongoing Nordic T1G2-G3 Bladder Sparing Study with monitored data available were included in the study. Data on residual tumours at second-look resection were compared to basic patient and tumour characteristics.

Neoadjuvant cisplatinum based combination chemotherapy in patients with invasive bladder cancer: a combined analysis of two Nordic studies.

Objectives: A Nordic collaborative group assessed the effectiveness of cisplatinum based combination chemotherapy prior to cystectomy in two consecutive trials. We analyzed overall survival in all patients and in prespecified subgroups defined by preoperative T-stage, gender and age.

Methods: The studies included in 1985-1997 620 patients with clinically T1G3, T2-T4aNXM0 urothelial bladder cancer and WHO performance View Article and Find Full Text PDF

DNA cytometric features in biopsies of TaT1 urothelial cell cancer predict recurrence and stage progression more accurately than stage, grade, or treatment modality.

Objectives: To compare retrospectively the predictive value for recurrence and stage progression of DNA ploidy and S-phase fraction by flow cytometry and highly automated ultrafast image cytometry (ICM) in biopsies of TaT1 urothelial cell carcinomas (UCCs) of the urinary bladder with stage, grade, other pathologic features, and treatment.

Methods: Three experienced pathologists reviewed the stage and grade of 228 UCCs; 193 (85%) consensus cases were analyzed further. We had enough material for single-cell suspensions for both flow cytometry and ICM in 183 cases (94.
