Pregnancy hopes for
cancer victims

THE first
human pregnancy after an ovarian transplant could be weeks
away, the scientist who pioneered the procedure said
yesterday.
A clinic in the United States has
already tried to fertilise the eggs of two cancer patients
who have had the operation, and a healthy pregnancy is only
a matter of time, the conference in San Antonio, Texas, was
told.
Kutluk Oktay, of Cornell University,
who is leading the research, said his prospects of success
would be greatly enhanced by this week’s announcement that a
rhesus monkey with transplanted ovaries had given birth to a
healthy infant, the first such success in a primate.
The developments will bring hope to
thousands of women who would otherwise be left sterile by
cancer treatment. These patients could have an ovary removed
and frozen before starting chemotherapy, which would be
thawed and re-implanted at a later date. Dr Oktay is the
world’s leading expert on ovary transplantation in people:
in 1997 he conducted the first procedure of its kind. He
recently recovered eggs from transplanted ovaries of two
patients and attempted to fertilise them.
While attempts have yet to work, Dr
Oktay said the work was ongoing and that a pregnancy was not
far away. “We are making significant strides,” he said. “We
have been able to collect eggs, we are just not yet able to
produce fertilisation.”
Both patients whose eggs Dr Oktay has tried to fertilise are
cancer survivors in their forties. One contracted cervical
cancer at the age of 37, the other breast cancer at 35.
Should the cervical cancer patient conceive, her embryo
would be carried by a surrogate mother as her treatment
required a hysterectomy. The breast cancer patient should be
able to carry her own child.
