SUBJECT: FURTHER INFORMATION OM THREE MARSHALIXSE GIRLS OPERATED ON
FOR REMOVAL OF THYROID NODULES (SEK ATTACHED COPY OF PREVIOUS
MEMO, THIS SUBJECT).
Dr. Robert A. Conard, Medical Department, Broekhaven National Laboratory,
who has responsibility for conducting the clinical surveys, reports:
"Sections of the nodules have been exemined by « number of pathologists
including Drs. &.-Warren, G. H. Rlink, H. A. Jehnson and $. Lindsay.
The
concensus is that the nodules are benign, though with certain bizarre areas,
and resemble iodine deficiency sdenomats."
Dr. ‘Lindsay noted that the nodules in Jonge lap cases are similar to
ones he has seen in children following LI
therapy. This Division has a
file of Dr. Lindsay's histological reports snd a review paper by Lindsay
and Chatkoff, Cancer Research, 24:1099, 1964.
The radiation dosages which these children's thyroidsa msy have received
are being re-evaluated by Dr. John Gefmen's group, Lawrence Radiation
Laboratory.
It should be added that nodules in the thyroid glenda of young people
frequently become malignant in the course of time. Therefore, while
these which were removed promptly efter discovery were not malignant,
there is 2 chance that in time they might have assumed neoplastic
characteristics.
February 1965.
Dr. Conard’s next clinical survey will take place in
