hCG regression after treatment in active and regressed extrauterine pregnancies.
The regression of hCG levels was studied in the maternal serum of 15 cases of tubal pregnancies (6 regressed and 9 active). Measurements of the hCG values were made before the operation and after 12, 24, 48, 72, 96, 120 and 192 hours. The mean hCG values in the groups of the regressed and active cases, before treatment, were 479.4 +/- 266.4 mIU/ml and 6334.0 +/- 932.1 mIU/ml, and after 192 h 4.8 +/- 0.4 mIU/ml and 115.8 +/- 37.9 mIU/ml, respectively. The hCG mean values in both groups showed the same exponential regression pattern and the percentage decrease in the hormone level in the period of time between 0 and 192 h was 98%. The mean values of the hormone in both groups showed significant differences (p less than 0.001) during the whole time interval observed.
