PURPOSE We report the 5-year followup of a randomized comparison of mitomycin C and bacillus Calmette-Guerin (BCG) in patients with superficial bladder carcinoma. Recurrence, progression and survival rates, crossover results, prognostic factors and long-term side effects were analyzed. MATERIALS AND METHODS A total of 261 patients were enrolled in the(More)
PURPOSE Chemotherapy is widely used in patients with locally advanced bladder cancer but until now there has been no conclusive evidence that this therapy improves survival. The Nordic Cooperative Bladder Cancer Study Group conducted a randomized phase III study to assess the possible benefit of neoadjuvant chemotherapy in patients with bladder cancer(More)
Human papillomavirus (HPV) detection was done using the polymerase chain reaction technique on tumor tissue from 44 patients with transitional cell carcinoma of the urinary bladder. Only one of the 44 was associated with HPV infection. The HPV-positive patient was not known to have immunodeficiency or genital warts, and the tumor was not morphologically(More)
PURPOSE We examined the possibility for detecting sentinel nodes in patients with bladder cancer and whether the histopathological status of identified sentinel nodes reflected that of the lymphatic field. MATERIALS AND METHODS A total of 13 patients with bladder cancer who met the criteria qualifying them for radical cystectomy had intravesical(More)
A retrospective study of 232 bladder tumours with minimum follow-up 5 years is presented. The carcinoma was superficial in 66%, muscle-invasive in 31% and could not be staged in 3%. Primary treatment was mainly transurethral resection for superficial tumour, but was cystectomy or radiotherapy in 22 of 29 T1 G3. Of the superficial tumours, 71% recurred.(More)
Proliferative cell nuclear antigen (PCNA) expression was analyzed in formalin-fixed and paraffin-embedded specimens from patients with urinary bladder cancer using three different anti-PCNA monoclonal antibodies. In 20 recent cases a positive correlation was found between the extent and intensity of PCNA staining and grade of malignancy. In 95 specimens,(More)
Seventy-three TUR-T biopsies from bladder carcinoma were evaluated regarding microvessel density, defined as microvessel number (nMVD) and cross-section endothelial cell area (aMVD). A semi-automatic and a newly developed, automatic image analysis technique were applied in immunostainings, performed according to an optimized staining protocol. In 12 cases a(More)
PURPOSE We compared the efficacy and toxicity of long-term mitomycin C versus bacillus Calmette-Guerin (BCG) instillation in patients at high risk for recurrence and progression of superficial bladder carcinoma. MATERIALS AND METHODS Our randomized comparison study included 261 patients with primary dysplasia, or stage Tis, stage T1, grade 3 and multiple(More)
Conventional subjective visual grading of malignancy in bladder carcinoma suffers from poor standardization. In an attempt to improve this by image analysis we carried out a texture analysis of a total of 197 images from Feulgen-stained histological tissue sections. The textural features used were based on the spatial gray-tone co-occurrence probability(More)
To evaluate the influence of the volume of 2% lidocaine jelly as an anesthetic during cystoscopy 241 men and women received either 11 or 20 ml. jelly intraurethrally in a randomized, double-blind fashion. Pain was recorded on a visual analogue scale by the patient and on a 3-level scale by the physician. The pain scores according to the visual analogue(More)
