The incidence of choriocarcinoma

• USA and Europe 1: 20 000 – 40 000 pregnancies

• Asia, Africa,

Latin America 1: 500 – 1000 pregnancies

• Slovak Republic 1: 20 311 pregnancies

Clinical Features of Choriocarcinoma

• Choriocarcinoma can follow any form of gestation

• Choriocarcinoma may have a long latent period

• Abnormal uterine bleeding

• About 5% of choriocarcinomas arise in salpinx after

ectopic pregnancy

• Elevation of HCG levels in serum

Imunohistochemická analýza

trofoblastových lézií - trofogram

1. Odlíšenie buniek trofoblastu od buniek inej

histogenézy

2. Determinácia buniek trofoblastu:

- pochádza lézia z IT v mieste implantácie ?

- pochádza lézia z IT chorionového typu ?

- ide o choriokarcinóm ?

3. Odlíšenie nezhubných lézií od pravých nádorov

Odporúčaný panel protilátok

• HSD 3B1 odlišuje trofoblastové lézie od non trofoblastových

• Cytokeratíny 8,18 odlíšia GTCH od mezenchýmových lézií

• Vimentín odlíši epitelové a mezenchýmové bunky od seba

• HCG odlíši choriokarcinóm od PSTT a iných lézií

• HPL odlíši PSTT od iných lézií

• Cyclin E odlíši ETT od PSN a iných lézií
