Uvod: Hiperhomocisteinemija je udružena sa karcinogenezom. Istraživanja
hiperhomocisteinemije i maligniteta u dečjem uzrastu su malobrojna i nedovoljna da se
donesu jasni zaključci o mogućem značaju homocisteina u ovoj populacionoj grupi.
Cilj rada je da se utvrde odnosi između vrednosti u krvi homocisteina, folne kiseline i
vitamina B12 sa vrstom i stadijumom maligne bolesti, utvrde efekti primenjene terapije
na promene u vrednostima homocisteina, folne kiseline i vitamina B12 i proceni značaj
homocisteina kao mogućeg markera tumorske aktivnosti.
Pacijenti i metod: Koncentracije homocisteina u plazmi, vitamina B12 u serumu i folne
kiseline u serumu određivane su pre i nakon primenjene terapije (operativno lečenje,
radioterapija i hemioterapija) kod 46 dece sa novodijagnostikovanim malignim
oboljenjem (solidni tumori i limfoproliferativna oboljenja). Ispitanici su bili uzrasta od 2
meseca do 18 godina.
Rezultati: Koncentracije homocisteina kod dece sa malignim oboljenjem su... bile
značajno niže nakon sprovedenog lečenja (p<0,01). Koncentracija vitamina B12 kod
dece sa malignim oboljenjem je bila značajno viša nakon sprovedene terapije (p<0,05).
Takođe je utvrđeno da su vrednosti koncentracije folne kiseline kod dece sa malignim
solidnim tumorima bile značajno više u odnosu na decu sa malignim
limfoproliferativnim i plazma ćelijskim oboljenjima (p<0,01). Istraživanje je pokazalo
da se u višim stadijumima maligne bolesti očekuju i više koncentracije homocisteina
(p<0,05).
Zaključak: Homocistein bi mogao biti marker malignih bolesti kod dece. Neophodna
su dalja ispitivanja kako bi se utvrdio značaj homocisteina, folne kiseline i vitamina B12
u malignitetu dečjeg uzrasta.
Background: Hyperhomocysteinemia is associated with carcinogenesis. There is little
available research on hyperhomocysteinemia and malignancy in children, and is
insufficient to draw a definitive conclusion as to the possible importance of
homocysteine for this population group.
The aim of the present study was to determine the blood levels of homocysteine, folic
acid and vitamin B12 in accordance to type and stage of malignant disease, to establish
the effects of the adjacent therapy on homocysteine, folic acid and vitamin B12 levels as
well as to estimate the importance of homocysteine as possible tumor marker.
Patients and methods: Forty-six children with newly diagnosed malignant disease
(solid tumors and lymphoproliferative disease) were included in the present study. The
patients were between two months and 18 years of age.
Results: The plasma concentration of homocysteine in children with malignant disease
was significantly lower following treatment (p<0.01). The con...centration of vitamin B12
in children with malignant diseases was significantly higher following treatment
(p<0.05). The concentration of folic acid in children with malignant solid tumors was
demonstrated to be significantly higher than in children with malignant
lymphoproliferative and plasma cell diseases (p<0.01). The study demonstrated that the
children with higher stages of malignant disease had higher levels of homocysteine
(p<0.05).
Conclusion: Homocysteine could be a marker of malignancy in children. Further
research is needed to establish the importance of homocysteine, folic acid and vitamin
B12 in pediatric malignant diseases.
