PURPOSE We determined the role, if any, of 1 and 5 instillations of intravesical mitomycin C in the treatment of newly diagnosed superficial bladder cancer. MATERIALS AND METHODS A multicenter randomized clinical trial was done involving 502 patients with newly diagnosed superficial bladder cancer. After complete transurethral resection patients with(More)
To evaluate human risk for Chagas disease, we molecularly identified blood meal sources and prevalence of Trypanosoma cruzi infection among 49 Triatoma sanguisuga kissing bugs in Louisiana, USA. Humans accounted for the second most frequent blood source. Of the bugs that fed on humans, ≈40% were infected with T. cruzi, revealing transmission potential.
Serum prostate-specific antigen (PSA) levels were studied in the EORTC trial of zoladex plus flutamide versus orchidectomy in metastatic prostatic cancer. Forty-four of 60 patients had a decrease of PSA to less than or equal to 10 ng/ml at 3 to 6 months after treatment. The combination of a PSA less than 10 ng/ml after 3 to 6 months treatment and less than(More)
The incidence of incontinence in a series of 135 consecutive stroke patients was 51% (urine) and 23% (feces) within one year. In 75% the urinary incontinence started within the first two weeks, and in 41% it had cleared during that time. Incontinence at onset is associated with measures of severity of stroke (and of immobility for fecal incontinence). Among(More)
This report is the final analysis of an EORTC Genito-Urinary Group Phase III trial (Protocol 30805) comparing orchidectomy, orchidectomy plus cyproterone acetate 50 mg 3 times a day and stilboestrol 1 mg daily in the management of metastatic carcinoma of the prostate. Three hundred and twenty-eight eligible patients admitted into the study have been(More)
We treated 191 patients with histologically proved locally advanced stage (T3 or T4) and/or metastatic prostate cancer with a biodegradable depot formulation of a luteinizing hormone-releasing hormone analogue (Zoladex). After an initial increase in serum testosterone in week 1 of therapy a continuous decrease of testosterone to castrate levels was(More)
In a randomized phase III trial performed by the Urological Group of the European Organization for Research on Treatment of Cancer low dose estramustine phosphate (280 mg. twice daily for 8 weeks and 140 mg. twice daily thereafter) was compared to diethylstilbestrol (1 mg. 3 times daily) in patients with stages T3 to T4, M0 or M1 prostatic cancer. Of 248(More)
Data are presented on a group of cases of primary carcinoma of the bladder, detailing red cell surface blood group antigenic phenotypes, serum haptoglobin phenotypes, and some red cell isoenzyme phenotypes. Account is taken of the stage of the disease at presentation. The results are compared with corresponding phenotype frequencies in groups of presumed(More)
Triatoma dimidiata is the most important Chagas disease insect vector in Central America as this species is primarily responsible for Trypanosoma cruzi transmission to humans, the protozoan parasite that causes Chagas disease. T. dimidiata sensu lato is a genetically diverse assemblage of taxa and effective vector control requires a clear understanding of(More)
