To the problem of risk factors in malignant transformation of trophoblastic tumor in women of the Irkutsk region

During the 1993-2004 period, 491 cases of tropfoblastic disease in pregnant women of the Irkutsk region were studied. Epide-miologic researches have allowed us not only to reveal a number of factors increasing or reducing risk of malignant transformation of tropfoblast in patients with trophoblastic disease but also to estimate a degree of the relative risk of each of them.
