I found this study about Edward Syndrome, trisomy 18, in Japan. Here are the main points.

1. The prognosis of trisomy 18 is lethal.

2. Sometimes, however long-term survival cases have been recognized.

3. In Japan a study of 7 previously published reports of mortality and 31 cases was conducted.

4. A data pool of 179 cases of trisomy 18 from 8 institutions was analyzed.

5. The mortality rates within 24 hours, 7, 28, 60, 180, and 365 days from birth were 14.84% (19/128), 31.01% (40/129), 56.25% (72/128), 64.08% (66/103), 82.17% (106/129), and 90.90% (140/154), respectively.

6. Fourteen of the 154 patients (9.09%) survived for more than 1 year.

7. Trisomy 18 children who have survived over 7 months after birth may have a high probability of long-term survival.

8. About 50% of infants with trisomy 18 die within 1 month after birth.

9. About 10% of patients survive over 1 year in Japan.

“These findings comprise Asia’s first clinical statistics concerning trisomy 18, in which the data were collected from multiple institutions.

So, how much chance does the baby in your womb need for survival before you give the little one up for lost even before you s/he is born?
