Summary

Studies were performed to determine (1) hormonal regulatory patterns associated with osteosarcoma; (2) in vitro estrogen and progesterone effects on chondrocyte and osteosarcoma cell DNA synthesis and (3) the effect of estrogen administration upon the clinical course of osteosarcoma.

Glucose tolerance, serum insulin, growth hormone, and somatomedin levels were studied in nine adolescents with osteosarcoma. Abnormal carbohydrate metabolism was manifested in all cases. Somatomedin assays were elevated in eight of nine patients.

In vitro studies revealed that estrogen and progesterone resulted in significantly suppressed DNA synthesis by osteosarcoma cells.

Clinically estrogen was demonstrated to be effective in correcting the abnormal pattern of glucose and insulin metabolism in two of four patients.

Résumé

Les études entreprises ont permis de déterminer:

  • -les types de régulation hormonale rencontrés dans les cas d'ostéosarcome.

  • -in vitro, les effets oestrogènes et de la progestérone sur le chondrocyte et la synthèse de DNA au niveau de la cellule cancéreuse.

  • -l'effet des oestrogènes sur l'évolution clinique de l'ostéosarcome.

L'étude a porté sur la tolérance au glucose, le taux d'insuline, d'hormone de croissance et de somatomédine chez 9 adolescents atteints d'ostéosarcome.

Dans chaque cas, le métabolisme des hydrates de carbone était perturbé le taux de somatomédine était élevé chez huit patients.

Les études réalisées in vitro ont montré que la synthèse de DNA est arrêtée au niveau des cellules cancéreuses, en présence d'oestrogène et de progestérone.

Sur le plan clinique chez deux patients sur quatre, il a été démontré que l'oestrogène redresse les déviations du métabolisme du glucose et de l'insuline.
