Is occupational exposure to antineoplastic drugs routinely monitored?

Yes, occupational exposure to antineoplastic drugs (chemotherapy and cytotoxic drugs) is routinely monitored in some healthcare settings to assess the extent to which healthcare workers are exposed to these hazardous substances. Various analytical methods are used, such as measuring drug levels or their metabolites in workers' urine, or taking surface swab samples from workplace environments to determine contamination levels [1].

While these drugs are essential for saving the lives of cancer patients, exposure can cause health harm to healthcare workers, including long-term organ damage, fertility issues, and even cancer [1]. Therefore, regular monitoring helps identify risks and implement appropriate preventive measures.

Why is monitoring occupational exposure important?

Antineoplastic drugs are designed to be harmful to cancer cells, but they can also affect healthy cells and tissues. Healthcare workers, especially pharmacists and nurses who prepare and administer these drugs, are at the highest risk of exposure [1]. Other at-risk workers include physicians, operating room staff, shipping and receiving personnel, cleaners, laundry workers, and waste disposal workers [1].

Exposure to these drugs can lead to acute or chronic health effects, such as damage to the liver, kidneys, bone marrow, lungs, and heart, as well as temporary or permanent infertility, impacts on reproduction and the developing fetus in pregnant women, hearing impairment, and an increased risk of cancer [1]. Therefore, monitoring contributes to evaluating the effectiveness of safety measures and determining the need for improvements to protect worker health.

How is exposure to antineoplastic drugs monitored?

Several methods are used to assess occupational exposure to these drugs. One common method is analyzing workers' urine samples to detect the presence of the drugs themselves or their metabolites [1]. Other biological indicators are also used to assess exposure, such as DNA mutations and chromosomal damage [1].

In addition to biological monitoring of workers, environmental surface swabbing is conducted in workplaces to assess contamination levels [1]. Although there are limited studies on air sampling, many studies have been published regarding surface swab sampling for these drugs [1]. These analytical methods help document worker exposure and environmental contamination, providing important data for decision-making regarding the improvement of safety procedures.

Prevention measures and next steps

To reduce occupational exposure to antineoplastic drugs, healthcare workers must follow strict safety guidelines and use appropriate personal protective equipment (PPE) [2]. This equipment includes gloves, protective gowns, eye protection, and shoe covers [3]. Gowns should have long sleeves with elastic cuffs and be fluid-resistant [3].

It is important to remove and dispose of PPE safely after use to prevent the spread of germs and hazardous materials [3]. Workers must also immediately report any exposure or contamination incidents to supervisors.
