Mesure de l'index bras-cheville pour le dépistage des artériopathies oblitérantes périphériques

L'artériopathie oblitérante des membres inférieurs (AOMI) est un marqueur de l'athérosclérose systémique et est associée à une morbi-mortalité importante. L'anamnèse et l'examen clinique sont très peu sensibles pour le diagnostic d'AOMI raison pour laquelle on sous-estime largement sa vraie prévalence. La mesure de l'ABI est l'examen de choix pour le dépistage d'une AOMI. Il s'agit d'un test fiable, de courte durée et bon marché, qui peut être facilement appris et utilisé par le médecin de premier recours. Une fois le diagnostic d'AOMI posé, comme pour les autres maladies cardiovasculaires, des mesures médicamenteuses et non médicamenteuses doivent être mises en place, afin de modifier les facteurs de risque cardiovasculaires, freiner la progression de la maladie et prévenir les complications.

Clinical benefit of fulvestrant in postmenopausal women with advanced breast cancer and primary or acquired resistance to aromatase inhibitors: final results of phase II Swiss Group for Clinical Cancer Research Trial (SAKK 21/00).

BACKGROUND: The aim of this study was to evaluate the efficacy and tolerability of fulvestrant, an estrogen receptor antagonist, in postmenopausal women with hormone-responsive tumors progressing after aromatase inhibitor (AI) treatment. PATIENTS AND METHODS: This is a phase II, open, multicenter, noncomparative study. Two patient groups were prospectively considered: group A (n=70) with AI-responsive disease and group B (n=20) with AI-resistant disease. Fulvestrant 250 mg was administered as intramuscular injection every 28 (+/-3) days. RESULTS: All patients were pretreated with AI and 84% also with tamoxifen or toremifene; 67% had bone metastases and 45% liver metastases. Fulvestrant administration was well tolerated and yielded a clinical benefit (CB; defined as objective response or stable disease [SD] for >or=24 weeks) in 28% (90% confidence interval [CI] 19% to 39%) of patients in group A and 37% (90% CI 19% to 58%) of patients in group B. Median time to progression (TTP) was 3.6 (95% CI 3.0 to 4.8) months in group A and 3.4 (95% CI 2.5 to 6.7) months in group B. CONCLUSIONS: Overall, 30% of patients who had progressed following prior AI treatment gained CB with fulvestrant, thereby delaying indication to start chemotherapy. Prior response to an AI did not appear to be predictive for benefit with fulvestrant.
