An injection to help kill off the most deadly cancers including breast, bowel and cervical tumours has been created by scientists

LONDON: An injection to help kill off the most deadly cancers including breast, bowel and cervical tumours has been created by scientists.

The drug, which is already being tested on patients, shrinks tumours and stops them from
spreading.

Cancer is much easier to treat, and even cure, with chemotherapy and other drugs when it is confined to one part of the
body.

Thousands of lives a year could be saved by the vaccine, which can also be effective against pancreatic and ovarian cancers, its creator Professor
Ray Iles said. He believes the injection could be on the market in as little as

five years.

Despite advances in medicine, the six cancers claim more than 40,000 lives a year. Bladder cancer, the fourth most common form of the disease
in men, kills almost 5,000 Britons a year and only half are still alive five
years after diagnosis.

Pancreatic cancer, the disease-that claimed the life of Dirty Dancing star Patrick Swayze, kills 7,600 Britons a year. Patients
have just a 3 per cent chance of being alive five years after
diagnosis.

Breast cancer is Britain’’s most common form of the disease, with more than 45,000 cases diagnosed a year and around 1,000 lives lost a
month. The Middlesex University vaccine capitalises on the finding that some of
the most vicious tumours produce a hormone normally only found in

pregnancy.

Human chorionic gonadotropin, or hCG, forms the basis of pregnancy testing kits.

But research by Professor Iles, of Middlesex University, shows that a form of hCG is also made by around half of bladder and
pancreatic-cancers. Some breast, bowel, ovarian and cervical tumours also pump
it out. The most aggressive of tumours, they quickly grow and spread.

The injection, which is being developed in conjunction with U.S. firm Celldex
Therapeutics, revs up the immune system, directing it to destroy
hCG.

This shrinks tumours – and, crucially, stops them from spreading, or metastasising. The spread of the disease to other organs is most common cause of
death in the 155,000 cancer patients who die each year.

Professor Iles said: ”Not only are you causing the cancer to shrink, it is not metastasising.

If you come in with chemotherapy and surgery, you”ve got a cure.”

Tests on animals have already had ”extremely good” results and preliminary trials on
people show it to be safe.

The jab is now being given to 60 men and women newly diagnosed with bladder cancer.

Further, larger trials will be needed before it is deemed suitable for wide fertility-spread use. Professor
Iles said: ”The vaccine has the potential to help us make rapid advances in the
treatment of this invasive cancer.”

The destruction of hCG would also mean the jab acted as a contraceptive. However, women’’s fertility should return
to normal within a year after completing treatment.

A similar approach is being taken in the U.S. to tackle breast cancer.

Immune system expert Vincent Tuohy has created a drug that targets a protein produced by
breastfeeding women – and most breast cancers. He said: ”hCG looks like a very

promising target for early vaccine therapy against bladder cancer.”

Gedis Grudzinskas, a Harley Street doctor, said the research was ”exciting
stuff”.

Up to 20,000 people die every year because the care of cancer and stroke sufferers is not as good as in Europe. If NHS care was as effective as
the best on the Continent, 50 lives could be saved a day, according to Health
Secretary Andrew Lansley. He said he would improve the situation by getting rid
of ”process” targets, which measure the NHS on how long it takes to treat
patients, and replacing them with ”outcome” measures – how it improves
health.

Patients suffering from some cancers are twice as likely to survive as patients diagnosed in the early 1970s, figures have

revealed.

Breast, bowel and ovarian cancer survival rates have shot up, as have those for non-Hodgkin’’s lymphoma.

The percentage of women likely to survive breast cancer for at least 10 years has jumped from 40 per cent to 77
per cent, while the figure for both sexes for bowel cancer has risen from 23 per
cent to 50 per cent.

And twice as many women with ovarian cancer survive (18 per cent to 35 per cent).

Professor Michel Coleman, head of Cancer Research UK’’s cancer survival group, which calculated the figures, said: ”These
big increases in long-term survival since the 1970s reflect real progress in
cancer diagnosis and treatment.”
