Gene therapy threat to cancer nurses
Cancer drugs are highly toxic
Tight safety controls are needed to ensure nurses are not exposed to risk when administering state-of-the-art gene therapy to cancer patients, researchers have warned.
She warned that history could repeat itself with the advent of new gene therapy techniques under which genetic material is introduced into the body of cancer patients using host viruses.
An investigation by the Robert Gordon University School of Nursing and Midwifery, Aberdeen, found that nurses who administer anti-cancer drugs showed many inconsistencies in their practice.
The nurses were found to wear different kinds of protective clothing, had different ways of checking drugs, and took different actions when drugs were spilled.
Many simply had not been properly trained to handle the medications.
The findings were echoed by a second study by Dutch nurses who specialised in cancer care.
"We are all involved in manipulating, preparing or administering cytotoxic medication," they said.
"These drugs are all more or less irritating, carcinogenic, mutagenic or teratogenic (capable of causing birth defects), yet they can be found in the urine of health care workers."
Ms Batchelor said the European Union had now drawn up protocols for the handling of anti-cancer drugs.
She said similar regulations were needed for gene therapy.
It was possible that contamination could infect nurses with the host virus, or that there may be health risks from the introduction of foreign genetic material.
She said: "Let's not make the same mistakes that we did in the past, let's be careful with gene therapy and let's monitor nurses from the start.
"We do not know what the risks are of transferring genetic material, but we have to protect workers from risks that are as yet unknown."
