Introduction:

Hydatidiform mole is the most common form of gestational trophoblastic disease. The quantification of serum beta-hCG has important value in its diagnosis and prognosis, however in Colombia there are no references of its values according to the type of mole or risk factors.

Objective:

To study the behavior of beta-hCG values according to the type of mole and the risk factors.

Materials and Methods:

74 cases with diagnosis of hydatidiform mole were studied in the pathology department of the Industrial University of Santander between 2005 and 2014. It was recorded from the data provided by the clinical history: smoking habit, blood sample, indication of the EMA-CO regimen, sociodemographic and gyneco-obstetric antecedents and the beta-hCG concentration prior to the evacuation treatment.

Results:

63 cases presented valid measurements of beta-hCG. In the analysis nonparametric tests with a level of significance of 10% were used. The median beta-hCG for complete and partial mole was 270 852 IU / L and 40 379 IU / L respectively. There was a significant difference for beta-hCG values between mola groups (p <0.0001). For the diagnosis of complete mole, a cut-off point of 170,000 U / L showed a sensitivity of 91.5% and a specificity of 75%. The EMA-CO indication showed a significant association with beta-hCG values (p = 0.066); associations with smoking (p = 0.118) and multiparity (p = 0.111) were not significant.

Conclusion:

The quantification of beta-hCG helps to classify the type of mole although its diagnostic performance is modest. MÉD.UIS. 2018;31(1):39-46.
