Abstrakt

Leczenie hormonalne raka piersi ma na celu ograniczenie oddziaływania endogennych estrogenów na komórki nowotworu. Odkrycie receptorów hormonalnych i poznanie ich znaczenia umożliwiło zastosowanie hormonoterapii w celowany sposób. U kobiet po menopauzie estrogeny wytwarzane są z androgenów. Aromataza jest enzymem, który powoduje konwersję androgenów do estronu. Inhibitory aromatazy blokują syntezę estrogenów. Leki z tej grupy wykazywały aktywność w leczeniu uogólnionego raka piersi, leczeniu uzupełniającym i w leczeniu neoadiuwantowym. Inhibitory aromatazy są lekami bezpiecznymi i wygodnymi w podawaniu. U chorych na uogólnionego raka piersi są bardziej aktywne niż tamoksyfen. W leczeniu neoadiuwantowym również wykazywały aktywność większą niż tamoksyfen. W leczeniu uzupełniającym przeprowadzono badania porównujące bezpośrednio tamoksyfen z inhibitorami aromatazy. Badano również leczenie sekwencyjne polegające na podawaniu przez 2–3 lata tamoksyfenu, a następnie inhibitora aromatazy (badano również odwrotną sekwencję). W ramieniu kontrolnym przez 5 lat podawano tamoksyfen. Przeprowadzono również badania nad znaczeniem wydłużonego stosowania inhibitorów aromatazy, w których po 5-letnim leczeniu tamoksyfenem podawano inhibitor aromatazy. Wyniki tych badań i przeprowadzonych na ich podstawie metaanaliz pozwalają na rekomendowanie stosowania inhibitorów aromatazy w leczeniu uzupełniającym.
