ECCLU 2011 - B. Tombal - Side-effects of anti-androgen therapy
4 likes1,602 views
The document discusses the long-term side effects of androgen deprivation therapy (ADT) for prostate cancer, including increased risks of osteoporosis, cardiovascular events, sarcopenic obesity, and bone loss. It provides evidence that ADT increases standard cardiovascular risk factors and cardiovascular events. While the effect on cardiovascular mortality is disputed, age and pre-existing conditions are the main risk factors. Exercise and drugs like SERMs may help mitigate side effects, but do not reduce cardiovascular events. Careful management of known risk factors is important when treating with ADT.

Editor's Notes
- #4: Testosterone is the most important circulating hormone in the male. Besides being essential for the development of male characteristics and male sexual organs it also has effects on most of the major organs, such as Brain, Muscle, Kidney, Bone Marrow, Bone, Liver, and Skin. As men age, testosterone levels decrease, and these decreasing levels in testosterone may present the following clinical problems: Sexual dysfunction Decreased Muscle Mass Increased ratio of fat to lean body mass Decrease in Bone Mineral Density and/or Osteoporosis Decreased body hair Decreased hematopoiesis Poor ability to concentrate
- #9: La fatigue est un symptôme important ressenti en cours de traitement anti-cancéreux mais également à distance de ces derniers. Le Ginseng est une herbe chinoise qui a montré un intérêt dans le traitement de la fatigue lors d ’ études animales, ainsi que lors d ’ une phase pilote menée en 2003. Trois doses ont été testées dans cette étude pilote randomisée, en double aveugle, versus placebo, sur 8 semaines de traitement. L ’ évaluation a porté sur la détermination de la dose efficace sur la fatigue en suivant plusieurs échelles dont le BFI (Brief Fatigue Inventory), la sous échelle vitalité du SF 36 (Short Form 36) et une échelle analogique d ’ appréciation du bénéfice individuel du malade. Les 282 patients inclus, aux caractéristiques semblables, ont été répartis en 4 bras : placebo (69 patients), 750 mg/j (70 patients), 1 000 mg/j (72 patients), 2 000 mg/j (71 patients). Parmi eux, 175 ont été réellement analysés. Une efficacité semble être retrouvée pour les deux bras de traitement à plus forte dose (1 000 et 2 000 mg), à 8 semaines, quelle que soit l ’ évaluation (BFI, bien-être émotionnel et physique). Un net bénéfice a été perçu par les patients qui ont reçu les fortes doses de Ginseng. Les effets indésirables ont été modérés de grades 1 à 2 (troubles du sommeil et digestifs). Des aléas méthodologiques ont conduit à une critique de cette étude, bien que les résultats graphiques proposés aient été en faveur d ’ un intérêt du Ginseng aux doses de 1 000 et 2 000 mg/j.
- #10: Les bouffées de chaleur ont un impact important sur la qualité de vie. Le citalopram, antidépresseur, a été testé versus placebo en évaluant plusieurs posologies et schémas de traitements à 10, 20 et 30 mg/j. 254 patientes ont été incluses dans cette étude randomisée à 4 bras. Le citalopram a une efficacité largement significative sur l ’ intensité (score) et la fréquence des bouffées de chaleur, quelle que soit la dose. Aucune différence n ’ a été notée en termes d ’ efficacité entre les différentes doses de citalopram, 10 mg semblant la dose la mieux tolérée, bien qu ’ aucune différence significative n ’ ait été également retrouvée en termes d ’ effets indésirables avec les autres doses. Les différents traitements utilisés contre les bouffées vasomotrices ont été analysés. Tous les antidépresseurs testés (venlafaxine 75 mg/j, fluoxetine 20 mg/j, paroxetine 25 mg/j, sertraline 50 mg/j), ainsi que la gabapentine à 900 mg/j ont une efficacité significative versus placebo. Ces résultats appliqués devraient permettre une nette amélioration de la qualité de vie de nos patientes.

- #42: Denosumab has been evaluated in a large, double-blind, multicentre study in men receiving ADT This was a randomised, double-blind, placebo-controlled, multicenter study conducted in the United States, Canada, Mexico, and Europe of denosumab in 1468 men receiving ADT for hormone-sensitive, nonmetastatic prostate cancer. Background An equal number of patients were randomized to: SC denosumab 60 mg via 1 mL injection every 6 months (n = 734) Placebo every 6 months (n = 734) All patients were instructed to take daily supplements of ≥1 g of calcium and ≥400 IU of vitamin D. In July 2006, the study protocol was amended from 2 to 3 years to extend the treatment period for safety and fracture evaluation. Exploratory end points included: percent changes in BMD of the whole body and distal ⅓ radius, and changes over time in levels of PSA and markers of bone turnover.
- #43: Denosumab provides long-term protection from new vertebral fractures in patients receiving ADT; incidence of new vertebral fractures was reduced by 62% compared with placebo over 36 months.
