Számos közlemény beszámol tumoros betegek életminőségének javítására alkalmazott étrend-kiegészítők hatásáról, de mindezek élettani vizsgálata szegényes. A cékla számos, a szervezetben lezajló biokémiai reakcióutat, enzim- és metabolitszintézist befolyásol. Módszer: A szerzők hormonrezisztens és metasztatikus prosztatarák miatt taxán-kemoterápiában részesülő betegek életminőségének javítása érdekében kereskedelmi forgalomból származó természetes céklakészítményt adtak egy hónapon át 2×10 g dózisban 24 (életkor: 68±8 év) betegnek, akik 3,6±2,8 éve jelentkeztek először panaszaikkal. A kezelést követően 18 fő esetében tudták az adatokat kiértékelni. A rutin laboratóriumi vizsgálatok mellett a betegek PSA-, HbA 1c -értékeit, 9 citokin- és 3 növekedésifaktor-szintet, a redox-homeosztázis globális paramétereit, fémionháztartásuk néhány elemét, Zn- és szabadprotoporfirin-szintjét, transzmetiláló képességét a kezelés megkezdése előtt és egy hónap múlva határozták meg. Eredmények: Eredményeik azt mutatták, hogy a betegek döntő többségében a cékla kedvező hatása érvényre jutott, és a tumoros betegekre jellemző szignifikánsan magas Zn- és szabadprotoporfirin-szintek csökkentek, valamint a transzmetilezési folyamatok felgyorsultak. Következtetések: Eredményeik alapján úgy tűnik, hogy az általuk alkalmazott céklakészítmény mérsékelt és tartós fogyasztása kedvezően befolyásolja a betegek életminőségét, de több esetben megfigyelhető növekvő EGF-érték miatt szoros orvosi kontroll szükséges kemoterápiában részesülő prosztatarákos betegeknél.
