Cost-effectiveness of cancer screening

Editor

Quinn, et al's assessment of the effectiveness of cervical cancer
screening(1) is an indictment of the cost effectiveness of this screening
programme.

Cervical cancer is a rare disease that was declining before the
introduction of the screening programme. Quinn, et al say that the £132
million spent each year "might have prevented 800 deaths from cervical
cancer in 1997". That is £165 000 for each death that "might have been
prevented". That money could be better spent.

In 1911 an embryologist, Dr John Beard, published his trophoblastic
theory of cancer's origins(2). This taught that cancers were similar to
pregnancy trophoblast and, in a similar way, caused the production of
human chorionic gonadotrophin (hCG), well known now as the basis of the
urinary diagnostic test for pregnancy. In the middle of the century, H H
Beard (no relation) and colleagues used this principle to detect cancers
at a very early stage with great accuracy(3).

Although these pioneers received little attention, new research by
Acevedo and co-workers at the University of Health Sciences, Pittsburg,
Pennsylvania on cancer cell lines in vitro and in vivo has confirmed their
work(4-7).

The hCG urine test for pregnancy has a retail cost of less than £6.
It is quick and easy to use and accurate for a wide range of cancers. Its
use as a screening tool would not only save a great deal of scarce NHS
resources it would also help patients: detection of malignancies at a much
earlier stage; less anxiety due to long waiting times; a lower incidence
of false negatives and false positives; and no risk of mix-ups in tissue
samples at pathology laboratories.
