RESUMEN
BACKGROUND: Several French, Belgian and Dutch radiation oncologists have reported good results with the combination of limited surgery after external beam radiotherapy (EBRT) followed by brachytherapy in early-stage muscle-invasive bladder cancer. PATIENTS AND METHODS: Data from 12 of 13 departments which are using this approach have been collected retrospectively, in a multicenter database, resulting in 1040 patients: 811 males and 229 females with a median age of 66 years, range 28-92 years. Results were analyzed according to tumor stage and diameter, histology grade, age and brachytherapy technique, continuous low-dose rate (CLDR) and pulsed dose rate (PDR). RESULTS: At 1, 3 and 5 years, the local recurrence-free probability was 91%, 80% and 75%, metastasis-free probability was 91%, 80% and 74%, disease-free probability was 85%, 68% and 61% and overall survival probability was 91%, 74% and 62%, respectively. The differences in the outcome between the contributing departments were small. After multivariate analysis, the only factor influencing the local control rate was the brachytherapy technique. Toxicity consisted mainly of 24 fistula, 144 ulcers/necroses and 93 other types. CONCLUSIONS: EBRT followed by brachytherapy, combined with limited surgery, offers excellent results in terms of bladder sparing for selected groups of patients suffering from bladder cancer.

A single-blind, randomized endoscopic tolerance study was conducted to compare daily doses of flurbiprofen (Ansaid, Upjohn) at 100, 150, and 200 mg per day with 2,600 mg of aspirin per day. Ten normal volunteers were enrolled in each of the flurbiprofen groups, and five were enrolled in the aspirin group. Analysis of the mean gastric mucosal injury scores obtained on day eight revealed statistically significant lower mean scores (p = 0.05) in the 100-mg and 150-mg flurbiprofen treatment groups when compared with the 200-mg flurbiprofen group and the aspirin group. No significant differences were found between any of the treatment groups in duodenal mucosal injury scores. Mean scores for gastric mucosal injury in the three groups receiving flurbiprofen showed a definite dose relationship. The aspirin-treated subjects had significantly decreased uric acid levels (p = 0.006) and a significantly higher incidence of tinnitus (p = 0.04) compared with the flurbiprofen treatment groups. There was a poor correlation between subjective symptomatology and endoscopic pathologic findings.

The pharmacokinetics of ibuprofen (Motrin) are best described by a two-compartment open model. Ibuprofen pharmacokinetics are only minimally influenced by advanced age, the presence of alcoholic liver disease, or rheumatoid arthritis. Levels of ibuprofen in breast milk are negligible. In addition, ibuprofen can be combined with acetaminophen without altering the pharmacokinetic profile. However, although not yet clinically proved, the concomitant use of ibuprofen and aspirin appears to reduce ibuprofen plasma levels to less than half those observed with ibuprofen alone.
