VIEW TREATMENT
FOR CANCER FOUND
Or. James B. Murphy of Roche
feIIer Institute Tells of
Series of Tests.

NEW YORK, Nov. 17.-ExDeri- .
nnen+s in cancer that may revolution
izs the treatment Of that disea-sc Were
disclosed Tuesdav 10y DG. James g.
Murphy OF the RockefelleT institute.
His remarkable research work was
unfolded before the National Academy
OF Science during its session IN the
American Museum OF Natural History.
Or Murphys announcement caused
a distinct stir. he would not amPltfy
his mere recital OF facts as shown by
his experiments He declined 10 make
predictions. His facts, however, We're
conclusive Scientists present did not
hesitate 20 declare their conviction
that the theory Of cancer treatment
heretofore had been erroneous.
Experiment With Rats.
I'VE have conducted three series Of
experiments with rats suffering from
spontaneous cancer De said These
experiments were made with a. view
OF determining the role Of lympnocytes
in resisting cancer.
sLymPhOcytes. as hiss LONG been
known. are the white corpuScles IN
the blood which attack foreign tissues.
They attack generous grow tbs TOO,
but 10 what extent was not known.
These experiment. were made 20 find
out In the r-st Ferries of experiments
we took a number of rats with spon-
tsneous cancer and removed the can
Ger by operation. The animals were
then subjected TO X-ray treatment with
q view OF ST uulating the lymphocytes.
After this minute portion OF the
cancer WIS replaced in the groin OF
the animals We found that only 80
Der cent Of tne animals so treated were
again sJspc 1tibie to the disease. OF
this nurnre- cay PIP per cent showed
local recutE -o OF the cancer. Fifty
per cent were immune.
"In .hts series OF experiments the
average ti-1s Cor the appearance of
the graft ator innoCulatiOn was five
weeks ana four days.
The second series consisted Of
similar number Of rats from which we
abstracted the cancer by operation in
the same manner. In this case though.
we did not use %-rayS at all We
placed a minute portion of the cancer
into the snimaIs groin as in the first
experiment. with the following re-
suits:
Only 81 Per Cent Immune.
After an average period Of one
week and five days 9G.6 per cent Of the
animals showed suspectibiity 10 can
Ger. OF these 4S.5 Per cent showed
local recurrence Of cancer and only
"a per cent showed immunity from
the disease.
the same general lines were followed
with the exception of the Z-ray treat
ment After removing the cancer by
operation we treated the cancerOus
growth 10 X-rays. The animal was not
so treated. We then replaced a mi
mute portion OF the cancer in the ami
mails grCin.
The result Of this experiment was
that in every case the animal showed
susceptibility T. cancer and 40 per
cent 20 local occurrence Of cancer Not
a single animal ,as immune The
average time for tEa appearance of the
graft in this expe~ Ecut was only one
week ana three days.
This can lie summarized as fol-
lows: In experiment one so per cent
OF the animals were immune from the
disease In experiment two "a per
cent were Immune. while in expert
men three none were immune.
The time taken for the animals to
show susceptibility to the disease in
the three experiments was as follows:
Experiment one. five weeks and
four days. Experiment two, one week
and five days. Experiment three one
week and three DAYS
Not Tried on Human Beings.
How this treatment would apply TO
human beings I don't know. We have
only made these experiment at pres
ent.
Three kinds OF graft were used
during the experiments The auto
plastic graft-Cut out of body and
put back into the same b. dy-w1s the
one we achieved the best results with
