Abstract
ABSTRACT Occupational exposure to medical agents and ionizing radiation has been suggested as a possible risk factor for childhood cancer. However, the relationship between such exposure and pediatric malignant neoplasms has not yet been comprehensively studied. This cohort study aimed to investigate the association between parental occupational exposure to hazardous medical agents or ionizing radiation and the risk of childhood cancer in offspring. Data from a large birth cohort in Japan, which included 104 062 fetuses, were analyzed. The primary outcome was the development of leukemia or brain tumors diagnosed by community physicians during the first 3 years after birth. Exposure factors were medical agents, including anticancer agents, ionizing radiation, and anesthetics, handled by mothers during pregnancy or by fathers for 3 months before conception. The incidence of leukemia, but not of brain tumors, was higher in mothers exposed to anticancer drugs. Multivariable regression analysis showed that maternal exposure to anticancer drugs was associated with an increased risk of leukemia in offspring older than 1 year (adjusted relative risk, 7.99 [95% confidence interval, 1.98-32.3]). Detailed information obtained from medical certificates of patients with identified leukemia revealed no infant leukemia but acute lymphoblastic leukemias in the exposed group. Our findings suggest that maternal occupational exposure to anticancer drugs may be a potential risk factor for acute lymphoblastic leukemia in offspring older than 1 year. Effective prevention methods may be necessary to prevent maternal exposure to anticancer drugs and to reduce the risk of childhood malignant neoplasms.

Abstract
With increasing numbers of cancer cases, the use of antineoplastic agents is expected to rise. This will be accompanied by an increase in occupational exposure, which can cause unwanted health effects in workers. Our aim was to give an overview of genotoxic and epigenetic effects after occupational exposure to antineoplastic agents and to assess the concentration-effect relation. Four databases were searched for papers investigating genotoxic and/or epigenetic effects of occupational exposure to antineoplastic agents. Out of the 245 retrieved papers, 62 were included in this review. In this systematic literature review, we confirmed that exposure of healthcare workers to antineoplastic agents can lead to genotoxic damage. However, we observed a lack of data on exposure as well as genotoxic and epigenetic effects in workers other than healthcare workers. Furthermore, gaps in the current knowledge regarding the potential epigenetic effects caused by antineoplastic drug exposure and regarding the link between internal antineoplastic drug concentration and genotoxic and epigenetic effects after occupational exposure to antineoplastic agents were identified, offering a first step for future research.

Abstract
OBJECTIVE Antineoplastic drugs (ADs) are widely used in clinical practice and have been demonstrated to be effective in treating malignant tumors. However, they carry a risk of cytogenotoxicity for healthcare workers. Studies have reported that genotoxic biomarkers can be applied to assess the occupational health status of healthcare workers at an early stage, but results of different studies are variable. The objectives of the review were examine the association between long-term exposure to ADs and cytogenetic damage to healthcare workers. METHODS We systematically reviewed studies between 2005 and 2021 using PubMed, Embase and Web of Science databases that used cytogenetic biomarkers to assess occupational exposure to ADs in healthcare workers. We used RevMan5.4 to analyze the tail length parameters of the DNA, frequency of the chromosomal aberrations, sister chromatid exchanges and micronuclei. A total of 16 studies were included in our study. The studies evaluate the quality of the literature through the Agency for Healthcare Research and Quality. RESULTS The results revealed that under the random-effects model, the estimated standard deviation was 2.37 (95% confidence interval [CI] 0.92-3.81, P = 0.001) for the tail length parameters of the DNA, 1.48 (95% CI 0.71-2.25, P = 0.0002) for the frequency of chromosomal aberrations, 1.74 (95% CI 0.49-2.99, P = 0.006) for the frequency of sister chromatid exchanges and 1.64 (95% CI 0.83-2.45, P < 0.0001) for the frequency of micronuclei. CONCLUSIONS The results indicate that there is a significant association between occupational exposure to ADs and cytogenetic damage, to which healthcare workers should be alerted.

Abstract
Despite the benefits for patients as cancer treatment, antineoplastic drugs may cause adverse effects not only in patients but also in health care personnel. Apart from minor symptoms, antineoplastic agents can cause serious health problems. However, protection from occupational exposures to antineoplastic drugs varies between pharmacy staff and nurses. While protection used for pharmacy staff are more advanced, personal protective equipment seems to be the only protection for most nurses around the world. Exposure can never be totally prevented, but it should be minimized at all costs. Guidelines and recommendations have been published; however, these guidelines do not have legal enforcement power. This article aims to provide a literature review on the occupational exposure of health care personnel to antineoplastic drugs and to reflect the current status in Hong Kong.

Abstract
The purpose of this report is to offer a consensus opinion of ACVIM oncology diplomates and technicians on the safe use of cytotoxic chemotherapeutics in veterinary practice. The focus is on minimizing harm to the personnel exposed to the drugs: veterinary practitioners, veterinary technicians, veterinary staff, and pet owners. The safety of the patient receiving these drugs is also of paramount importance, but is not addressed in this statement. Much of the information presented is based on national recommendations by Occupational Safety and Health Administration, National Institute for Occupational Safety and Health, United States Pharmacopeia, and other published regulations. These directives reflect an abundance of caution to minimize exposure to medical personnel, but large-scale studies about the consequences of long-term occupational exposure are not available in veterinary medicine. Challenges in the delivery of optimal treatment safely and economically to veterinary patients in general practice without access to a veterinary oncologist or other specialist, because of costs or proximity, remain.

MUTATION RESEARCH-REVIEWS IN MUTATION RESEARCH 2017; 781:207-217.

Abstract
Many antineoplastic drugs used to treat cancer, particularly alkylating agents and topoisomerase inhibitors, are known to induce genetic damage in patients. Elevated levels of chromosomal aberrations, micronuclei, and DNA damage have been documented in cancer patients. Elevations in these same biomarkers of genetic damage have been reported in numerous studies of healthcare workers, such as nurses and pharmacists, who routinely handle these drugs, but results vary across studies. To obtain an overall assessment of the exposure effect, we performed a meta-analysis on data obtained from peer-reviewed publications reporting chromosomal aberration levels in healthcare workers exposed to antineoplastic drugs. A literature search identified 39 studies reporting on occupational exposure to antineoplastic drugs and measurement of chromosomal aberrations in healthcare workers. After applying strict inclusion criteria for data quality and presentation, data from 17 studies included in 16 publications underwent meta-analysis using Hedges' bias-corrected g and a random-effects model. Results showed the level of chromosomal aberrations in healthcare workers exposed to antineoplastic drugs was significantly higher than in controls. The standardized mean differences (difference of means divided by within sd) from all studies were pooled, yielding a value 1.006 (unitless) with p<0.001. Thus, in addition to the documented genotoxic effects of antineoplastic drugs in cancer patients, this meta-analysis confirmed a significant association between occupational exposure to antineoplastics during the course of a normal work day and increases in chromosomal aberrations in healthcare workers. Based on the studies reviewed, we were unable to accurately assess whether appropriate use of protective measures might reduce the incidence of genetic damage in healthcare workers. However, given the potential for increased cancer risk linked to increases in chromosomal aberrations, the results of this study support the need to limit occupational exposure of healthcare workers to antineoplastic drugs as much as possible.

Abstract
CONTEXT Hospital workers are at risk for genotoxic damage following occupationally exposure to xenobiotics. Pathologists are exposed to chemicals during their use in health care environments, particularly throughout inhalation of airborne agents, absorption through skin or contact with the patient's body fluids. OBJECTIVE We evaluated the level of genomic damage in a sample of 61 hospital pathologists (occupationally exposed to antineoplastic drugs and sterilizing agents) and 60 control subjects. MATERIALS AND METHODS Lymphocytes were analyzed by SCEs and CAs assays and genotyped for GSTT1, GSTM1, CYP1A1 Ile/Val, XPD (A751C) and XPC (A939C) gene polymorphisms. RESULTS Pathologists showed significantly higher frequencies of SCEs and CAs with respect to control subjects. GSTT1 null genotype was found to be associated with higher SCEs and CAs frequencies, whereas XPD 751 CC and XPC 939 CC genotypes only with a higher level of SCEs. DISCUSSION AND CONCLUSIONS The SCEs and CAs results are consistent with other published data, placing hospital workers as a category at risk for genotoxic damage caused by chronic exposure to xenobiotics. The higher levels of cytogenetic damage observed among GSTT1 null, XPD 751 and XPC 939 CC homozygote subjects confirm the importance of the genetic polymorphisms analysis associated to genotoxicological studies.

Abstract
Due to their increasing use, the residues of anti-neoplastic drugs have become emerging pollutants in aquatic environments. Most of them directly or indirectly interfere with the cell's genome, which classifies them into a group of particularly dangerous compounds. The aim of the present study was to conduct a comparative in vitro toxicological characterisation of three commonly used cytostatics with different mechanisms of action (5-fluorouracil [5-FU], cisplatin [CDDP] and etoposide [ET]) towards zebrafish liver (ZFL) cell line, human hepatoma (HepG2) cells and human peripheral blood lymphocytes (HPBLs). Cytotoxicity was determined by 3-(4,5-dimethylthiazol-2-yl)-2,5-diphenyltetrazolium bromide (MTT) assay and acridine orange/ethidium bromide staining. All three drugs induced time- and dose-dependent decreases in cell viability. The sensitivity of ZFL and HepG2 cells towards the cytotoxicity of 5-FU was comparable (half maximal inhibitory concentration (IC50) 5.3 to 10.4 μg/mL). ZFL cells were more sensitive towards ET- (IC50 0.4 μg/mL) and HepG2 towards CDDP- (IC50 1.4 μg/mL) induced cytotoxicity. Genotoxicity was determined by comet assay and cytokinesis block micronucleus (CBMN) assay. ZFL cells were the most sensitive, and HPBLs were the least sensitive. In ZFL cells, induction of DNA strand breaks was a more sensitive genotoxicity endpoint than micronuclei (MNi) induction; the lowest effective concentration (LOEC) for DNA strand break induction was 0.001 μg/mL for ET, 0.01 μg/mL for 5-FU and 0.1 μg/mL for CDDP. In HepG2 cells, MNi induction was a more sensitive genotoxicity endpoint. The LOEC values were 0.01 μg/mL for ET, 0.1 μg/mL for 5-FU and 1 μg/mL for CDDP. The higher sensitivity of ZFL cells to cytostatic drugs raises the question of the impact of such compounds in aquatic ecosystem. Since little is known on the effect of such drugs on aquatic organisms, our results demonstrate that ZFL cells provide a relevant and sensitive tool to screen genotoxic potential of environmental pollutant in the frame of hazard assessment.

Abstract
OBJECTIVE Concern exists regarding the possible hazards to the personnel handling anti-neoplastic drugs. The purpose of the present study was to assess the genotoxicity induced by anti-neoplastic agents in oncology department personnel. MATERIALS AND METHODS To do this, the frequency of chromosomal aberrations (CAs) induced in peripheral blood lymphocytes was assessed at G0 phase of the cell cycle using metaphase analysis, cytokinesis block-micronucleus (MN) assay and sister chromatid exchange (SCE) assay. These cytogenetic end points were measured among 71 nurses in oncology department and 10 drugstore personnel handling and preparing anti-neoplastic drugs. The results were compared to those of 74 matched nurses for age and sex not exposed to any anti-neoplastic agents. RESULTS There was no significant difference between the age of study subjects and control group (p > 0.05). The results showed that the mean frequency of cytogenetic damages in terms of CAs [chromatid breaks (p = 0.01), chromosome breaks (p = 0.005), total CAs (p = 0.001)], MN formation (p = 0.001), and SCE (p = 0.004) in lymphocytes of personnel handling anti-neoplastic drugs were significantly higher than those in control unexposed group. CONCLUSION Results of the present study demonstrate the cytogenetic damage in peripheral blood lymphocytes of oncology department personnel. Suitable training and proper knowledge when handling anti-neoplastic drugs are emphasized to avoid potential health hazards caused by cytostatic agents.

Abstract
BACKGROUND Cyclophosphamide is one of the most commonly used chemotherapy drugs worldwide. Data concerning environmental contamination and biological exposure of pharmacy personnel to this and other chemotherapy drugs are limited. OBJECTIVES To determine whether pharmacy personnel involved in preparing and checking cyclophosphamide doses were more likely to have detectable levels of this drug in their urine than non-oncology pharmacy personnel with no known contact with the drug, and to compare the degree of surface contamination with cyclophosphamide, methotrexate, and ifosfamide in the oncology pharmacy of a tertiary care pediatric hospital, where chemotherapy doses were prepared, and the main (control) pharmacy in the same institution, where no chemotherapy was prepared. METHODS Biological exposure to cyclophosphamide was compared between pharmacy personnel who did and did not handle this drug by determining whether participants had detectable amounts of cyclophosphamide in their urine. Environmental exposure to chemotherapy drugs was assessed by using surface wipes to determine the degree of surface contamination with various chemotherapy agents in the oncology pharmacy and the main (control) pharmacy. RESULTS On initial testing, cyclophosphamide was detected in the urine of all pharmacy personnel (n = 7 oncology personnel, n = 5 control personnel). However, it was determined that all control personnel had been exposed to the oncology pharmacy on the day of testing. Repeat testing of these individuals revealed no positive samples among those not exposed to the oncology pharmacy on the day of repeat testing. The sole positive result on retesting of control personnel was for a participant who had been exposed to the oncology pharmacy on the retest day. Surface wipe testing revealed contamination of the oncology pharmacy with cyclophosphamide and methotrexate before and after cleaning, as well as contamination with ifosfamide after cleaning. The main (control) pharmacy showed no evidence of contamination with cyclophosphamide, methotrexate, or ifosfamide. CONCLUSIONS The findings suggest that environmental contamination plays a role in biological exposure to cyclophosphamide. Measures to reduce environmental contamination from chemotherapy and biological exposure of pharmacy personnel when handling chemotherapy agents should be identified and implemented as a priority.

Abstract
OBJECTIVE To evaluate biological and environmental exposure to cyclophosphamide in nurses at a single institution. METHODS Biological exposure to cyclophosphamide in nurses administering cyclophosphamide compared with two control groups: nononcology nurses not administering cyclophosphamide and community members without recent hospital exposure. Environmental exposure to chemotherapy was measured using surface wipes taken from oncology and nononcology areas in the hospital. RESULTS More than one third of all nurses and no community controls tested positive for urinary cyclophosphamide. Oncology and nurse controls tested positive in equal numbers. Surface wipes were positive only in the oncology ward. CONCLUSION We have demonstrated elevated levels of cyclophosphamide in one third of all nurses and cyclophosphamide contamination of surfaces within the oncology patient environment. This suggests that environmental contamination plays a major role in biological exposure to cyclophosphamide.

Abstract
Exposure to chemotherapy is a health hazard for all personnel in facilities that store, prepare, or administer antineoplastic agents. Contamination levels have been measured as much as 15 times higher in the veterinary medicine sector than in human facilities. Recent publications in human and veterinary medicine indicate that exposure extends beyond the clinic walls to affect the patient's home and family. This article provides an update on the advances in chemotherapy safety, the current issues, and the impact on cancer management in veterinary medicine.

Abstract
Anti-cancer drugs are chemotherapeutic agents that are designed to kill or reduce proliferating cells. Often times, they interfere directly or indirectly with the cell's deoxyribonucleic acid (DNA). Some of these drugs can be detected in the ng/L concentration range in the aquatic environment and have the potential to be very persistent. Environmental risk assessment is available for only a few anti-cancer drugs, derived mainly from predicted data and excluding information on their metabolites and transformation products (TPs). Notably, there is no defined strategy for genotoxicity risk assessment of anti-cancer drugs, their metabolites and TPs in the environment. In fact, the presence of anti-cancer drugs in hospital and municipal wastewaters has not been clearly related to the genotoxic nature of these wastewaters. The few available studies that have sought to investigate the genotoxicity of mixtures derived from treating anti-cancer drugs prior to disposal seem to share the commonality of coupling analytical methods to measure concentration and genotoxic bioassays, namely the Ames test to monitor inactivation. Such limited studies on the environmental fate and effects of these drugs presents an area for further research work. Most importantly, there is a need to characterize the genotoxic effects of anti-cancer drugs towards aquatic organisms. Given current environmental risk assessment strategies, genotoxicity risk assessment of these drugs and their TPs would have to include a combination of appropriate analytical methods, genotoxicity bioassays, (bio) degradability and computer based prediction methods such as QSAR studies.

Abstract
Ciprofloxacin (CIP), tamoxifen (TAM) and cyclophosphamide (CP) which are often used in anticancer treatment are released in hospital effluent and into the environment. Although the concentrations are low (from ng/L to μg/L), no data exist concerning their ecotoxicological impact. In this study two biomarkers of early effect were performed on hepatic cells (HepG2): cell viability and genotoxicity (DNA breaks) using cell proliferative assay and comet assay, respectively. These data were compared with two standardized ecotoxicological tests: algaltoxkit F™ and microtox®. Cells were exposed to an increasing amount of an individual drug or in a mixture for 24, 48 or 72h. The time-exposure of bacteria and algae ranged between 5 and 30min and 72h, respectively. A non-monotonic dose-response on cell viability was observed when HepG2 cells were exposed to TAM alone or in the presence of CIP. The same scheme was observed with microtox® when the bacteria were exposed to the mixtures. On the other side, an individual drug does not induce any DNA breaks on hepatic cells, whereas a mixture leads to a dose dependent increase of DNA breaks. Similarly a positive response was observed with algaltoxkit F™ only with mixtures. Synergistic effects observed when drugs are in a mixture highlight the importance of investigating the ecotoxicological effects of contaminants at low concentrations and in mixtures.

Abstract
In the present study, we evaluated the induced genome damage in peripheral blood lymphocytes from a sample of nurses occupationally exposed to low doses of different chemicals. A comprehensive multi-biomarker approach using cytogenetic endpoints was employed for analyzing chromosomal aberrations (CAs) and sister chromatid exchange (SCE) assay. The study included 20 nurses and 20 control subjects matched in age, gender and smoking habits. Nurses were exposed to different chemicals, such as cytostatic drugs, anaesthetics, formaldehyde and other sterilizing gases. Significant differences were found between exposure group and control group in terms of SCEs frequency (p < 0.001) but not in terms of replication index value (p = 0.845) and CAs (p = 0.236). Regression analyses indicated that the age and the exposure years did not influence the amount of the chromosomal damage among nurses. Vice versa, among controls, a positive correlation was found between the number of SCEs and age. In conclusion, our results suggest that a continuous long-term exposure to low doses of chemicals could result in increased levels of SCEs among nurses. This data emphasize the importance of biomonitoring nurses and other hospital workers handling drugs.

Abstract
Purposes: (a) To measure the urinary excretion of antineoplastic drugs of three patients during 48 h after the administration of cyclophosphamide (two patients) and 5-fluorouracil (one patient). (b) To evaluate environmental contamination with antineoplastic drugs via excreta of patients in the home setting. (c) To evaluate exposure of family members to antineoplastic drugs by measuring the drugs in their urine during the 48 h after completion of the chemotherapy by the patients. Methods: Two patients were administered cyclophosphamide by i.v. bolus injection. One patient was administered 5-fluorouracil by i.v. bolus injection and thereafter immediately administered the same drug by continuous infusion for 46 h. Urine samples from the patients administered cyclophosphamide and their family members, and wipe samples from their home environment, were analysed for the unchanged form of cyclophosphamide. For 5-fluorouracil, the urine samples from the patient and the family member were analysed for the 5-fluorouracil metabolite α-fluoro-β-alanine. Wipe samples were analysed for 5-fluorouracil. Drugs were detected and quantified with gas chromatography in tandem with mass spectroscopy-mass spectroscopy or by high-performance liquid chromatography with ultraviolet-light detection. Results: A total of 35 and 16 urine samples were collected from the three patients and their family members, respectively. The drugs were detected in all samples. Cyclophosphamide was detected at levels of 0.03–7.34 ng/cm2 in 8 of the 12 wipe samples obtained from the homes of the patients administered cyclophosphamide. For the patient administered 5-fluorouracil, drug levels in his home environment were below the limit of detection. Conclusion: We demonstrated contamination of the home setting and exposure of family members to cyclophosphamide via the excreta of outpatient receiving chemotherapy. Exposure of the family member of the patient administered 5-fluorouracil was also demonstrated. These findings indicate the importance of strict precautions by the members of treated cancer patients as well as healthcare workers, to reduce the risk of exposure to antineoplastic drugs.

Abstract
The hazards of handling antineoplastic drugs have been raised and discussed in several studies. Introduction of new antineoplastics together with abuse of safety standards have contributed to the exposure risk for personnel who handle these substances. Interactions of antineoplastic drugs with biological structures vary according to the drug(s) and the individual's genetic susceptibility. This study was carried out to evaluate the genome damage induced by exposure to antineoplastic drugs in nurses (n = 20) and pharmacists (n = 18) working in the Oncology Department of Tanta Cancer Center. Thirty subjects matched in age, gender and smoking habit were selected as controls. Both chromosomal aberration analysis and micronucleus assay were used to evaluate genome damage in peripheral blood lymphocytes of the study subjects. The numbers of aberrant lymphocytes, as well as chromosomal aberration and micronuclei frequencies, were significantly increased in exposed personnel in comparison to matched controls. Compared with pharmacists, nurses showed notably higher level of chromosome damage. On the other hand, no significant difference in micronuclei frequency was observed between nurses and pharmacists. Correlation analyses pointed to the influence of age and duration of occupational exposure on the level of chromosome damage among exposed subjects. The results of this study confirmed that handling antineoplastic drugs without appropriate precautions imposed a genotoxic risk for exposed healthcare workers. These results address the need for regular biomonitoring of exposed personnel. In addition, they call attention to the need for proper implementation of intervention measures aiming to eliminate or significantly reduce worker exposure and prevent untoward biological effects.

Abstract
The majority of anticancer agents has in common DNA-damaging properties and affects not only target-cells but also non-tumour cells. Its genotoxicity has been demonstrated in experimental models and in cancer patients treated with chemotherapy. Health care personnel involved in the preparation and administration of chemotherapy is therefore at risk for adverse health effects, since most environmental sampling studies demonstrated that there is widespread contamination of work surfaces and equipments with anticancer drugs. Adherence to safety guidelines and proper use of personal protective equipment are insufficient to prevent significant absorption, as evidenced by the presence of detectable amounts of drugs in urine samples and increased frequency of genotoxicity biomarkers. In this minireview, a critical appraisal of the most important biomarkers used for the evaluation of occupational exposure to anticancer agents as well as a summary of the key findings from several studies published in this field is performed.

Abstract
Exposure assessment of health care workers to antineoplastic drugs (ADs) is still an open issue since new, critical, and emerging factors may put pharmacists who prepare hazardous drugs or nurses who administer anti cancer agents to an increased risk of developing adverse health effects. Overall, eight pharmacies and nine patient areas have been surveyed in this study. Wipe and pad samples were experienced during the surveillance program in four Italian health care settings. Urine samples were collected from workers handling ADs. Cyclophosphamide (CP), ifosfamide (IF), and gemcitabine (GEM) were detected in all the work environments by using a LC-MS/MS method-based capable of analysing all the three drugs simultaneously. In total, 54% of wipe samples were positive for at least one drug and 19% of pad samples were shown to be contaminated by cyclophosphamide. Pharmacies were generally more contaminated than patient areas with the exception of one site where a nurse had an acute exposure during the cleaning-up of an hazardous drug solution spill. In total, 22 urine samples collected from pharmacists and 78 urine samples from nurses had no detectable concentrations of any antineoplastic drugs. Despite the adherence to the recommended safety practices residue contamination on surfaces and floors has continued to be assessed in all the investigated sites.

Abstract
Anti-neoplastic agents are widely used in the treatment of cancer and some non-neoplastic diseases. These drugs have been proved to be mutagens, carcinogens and teratogens. To check the eventual effects of anti-cancer drugs on occupationally exposed Tunisian nurses, we used chromosomal aberration assay and micronucleus assay. Both parameters have been used to evaluate cellular DNA damage in the biological monitoring of occupationally exposed workers and each assay has its own aim .We used the proliferation rate index to evaluate the cytotoxic effect of antineoplastic drugs in exposed nurses. The frequency of binucleated micronucleated cells was significantly higher in nurses handling cytostatic drugs than in control. We detected also a significant increase of structural chromosomal aberrations. Control subjects generally had significantly higher values of proliferation rate index compared to expose ones. Our results confirm the genotoxic and the cytotoxic effects of antineoplastic drugs in blood lymphocytes circulation. This study points to the necessity to work under more safe and controlled conditions during the preparation and the administration of anti-cancer drugs.

Antineoplastični Lijekovi Kao Čimbenik Rizika u Radnom Okolišu: Mehanizmi Djelovanja na Razini Stanice i Pregled Metoda za Otkrivanje Njihovih Genotoksičnih UčinakaU članku je prikazana osnovna podjela antineoplastičnih lijekova prema mehanizmima djelovanja na razini stanice. Objašnjeni su mehanizmi genotoksičnosti najvažnijih vrsta lijekova koji se primjenjuju u okviru uobičajenih protokola za liječenje zloćudnih novotvorina. Navedena je važeća klasifikacija antineoplastika prema kancerogenom potencijalu, podaci o mutagenom potencijalu te je prikazana njihova podjela u skladu s anatomsko-terapijsko-kemijskim sustavom klasifikacije. Sustavno su prikazani najvažniji rezultati svjetskih i hrvatskih istraživanja na populacijama radnika izloženih antineoplasticima, provedenih u razdoblju 1980.-2009. s pomoću četiri najčešće primjenjivane metode: analize izmjena sestrinskih kromatida, analize kromosomskih aberacija, mikronukleus-testa i komet-testa. Objašnjena su osnovna načela navedenih metoda te raspravljene njihove prednosti i nedostaci. Biološki pokazatelji daju važne podatke o individualnoj osjetljivosti profesionalno izloženih ispitanika koji mogu poslužiti unaprjeđenju postojećih uvjeta rada i upravljanju rizicima pri izloženosti genotoksičnim agensima. Na osnovi prednosti i nedostataka citogenetičkih metoda zaključeno je da je mikronukleus-test, koji podjednako uspješno dokazuje klastogene i aneugene učinke, jedna od najboljih metoda dostupnih za otkrivanje štetnih djelovanja antineoplastičnih lijekova koji su u aktivnoj primjeni.

Abstract
Authors compared the incidence of chromosomal aberrations (CAs) of workers occupationally exposed to cytostatics (group EXP1) or anaesthetics (group EXP2) in relationship to polymorphism of GSTM1, GSTP1 and GSTT1 genes. The cytogenetic analysis for chromosomal aberrations frequency and for polymorphisms of genes the PCR and PCR-RFLP method were used. Statistically higher frequency of total CAs was detected in both exposed groups: group EXP1 1.90±1.34%; Mann-Whitney U-test, p=0.001; group EXP2 2.53±1.46%, p=0.0008) as compared to control (1.26±0.93%). In group EXP2 was detected statistically higher frequency of aberrations CSA-type as compared to CTA-type. In xenobiotic metabolizing genes for GST higher frequency of total CAs and constituent types chromatid-type aberrations (CTAs) and chromosome-type aberrations (CSAs) of genes GSTM1 and GSTT1 with null genotype was detected. Statistically significant difference was detected only in CSA-type of aberrations in GSTT1 gene. In gene GSTP1 was not detected any difference in frequency of aberrations in presence of the variant allele. Presented results point out importance of individual susceptibility in evaluation of genotoxic agents of anaesthetics or cytostatics.

Abstract
PURPOSE This study was conducted to determine the problems about working conditions, employee rights and working life of oncology nurses in Turkey who administer cytotoxic drugs and to determine whether or not the existing practices are appropriate with national laws, comparing the current practices in private, university and government hospitals. METHOD The study was designed as an analytic descriptive survey. The research settings took place in nine hospitals of Istanbul, Turkey. The participants were 171 nurses who worked in oncology units and administered cytotoxic drugs. Data were collected using a questionnaire, which was developed by the investigators to determine working conditions of oncology nurses. FINDINGS The oncology nurses overworked, had insufficient time off work, did not receive compensation for overtime work, would not be protected if they were pregnant or breastfeeding, and faced deficiencies in occupational health and safety. CONCLUSIONS AND RECOMMENDATIONS Oncology nurses were exposed to working conditions that were only partly appropriate with national laws and International Labor Organization standards for health care workers were disregarded. Nurses need to be educated during the preparation and administration of chemotherapy drugs and protection against exposure as soon as possible. Chemotherapic drugs need to be prepared in a hood (biological safety cabin), but when unavailable minimal protection measures, including aprons, goggles, masks and latex gloves, need to be worn.

Abstract
OBJECTIVES The aim of the preset study was to evaluate the applicability of a closed system device to protect against occupational contamination and exposure to antineoplastic drugs in the work environment of a hospital. METHODS We compared the contamination by and exposure to cyclophosphamide (CPA) between a conventional mixing method and a mixing method using a closed system device. Wipe samples in the preparation room, gloves samples and 24-h urine samples of pharmacists preparing antineoplastic drugs were collected. Working surfaces inside the biological safety cabinet (BSC), front side of the air grilles of the BSC, stainless steel trays, working table and floor were wiped. At first, sample collection was done on 5 days over an interval of 2 weeks using the conventional mixing method. After 2 weeks training for using the closed system device, sample collection was done 5 days over an interval of 2 weeks using the closed system device. RESULTS When pharmacists prepared antineoplastic drugs by the conventional method, CPA was detected from all wipe samples, and the mean and median concentrations of CPA were 1.0 and 0.16 ng cm(-2), respectively (range was from 0.0095 to 27 ng cm(-2)). When pharmacists prepared antineoplastic drugs with a closed system device, CPA was detected from 75% of the wipe samples at mean and median concentrations of 0.18 and 0.0013 ng cm(-2), respectively (the range was from lower than detection limit to 4.4 ng cm(-2)). Using the closed system device significantly reduced the surface contamination of CPA for all wipe sampling points in the preparation room (Mann-Whitney's U-test). The range of CPA of glove samples used in the conventional method and closed system device ranged from lower than detection limit to 3200 ng per glove-pair and from lower than detection limit to 740 ng per glove-pair, respectively. Using the closed system device significantly reduced the gloves contamination of CPA (Mann-Whitney's U-test). The range of urinary CPA of six pharmacists preparing the antineoplastic drugs with the conventional method and closed system device ranged from lower than detection limit to 170 ng day(-1) and from lower than detection limit to 15 ng day(-1), respectively. Using the closed system device significantly reduced the amount of urinary CPA in pharmacists preparing the antineoplastic drugs (Wilcoxon's signed ranks test). CONCLUSIONS We concluded that a closed system device can reduce occupational contamination and exposure to antineoplastic drugs in the hospital work environment.

Abstract
Authors evaluated the incidence of total chromosomal aberrations (CA) and their types – chromatid-type (CTA) and chromosome-type (CSA) in peripheral blood lymphocytes from 72 oncologic unit's workers occupationally exposed to cytostatics in relationship to polymorphisms of DNA repair genes XPD, XPG and XPC. The cytogenetic analysis was used for determination of chromosomal aberrations frequency and PCR-RFLP method for polymorphisms of genes. Statistically higher frequency of total CA was detected in exposed group as compared to control (1.90±1.34% vs. 1.26±0.93%; Mann-Whitney U-test, p=0.001). There was not detected any difference between CTA and CSA (0.92±1.04% vs. 0.98±1.17%). Similarly, in genes XPD exon 23 and XPC exon 15 wasn't detected any difference neither in total chromosomal aberrations nor in CTA and CSA types. Statistically significant decrease of total chromosomal aberrations and CTA-type with presence of variant allele C was detected in gene XPG exon 15. Authors pointed out the importance of individual susceptibility factors in evaluation of effects of genotoxic agents, in that event, when the concentration does not meet the occupational exposure limit.

Abstract
To clarify genotoxic effects of occupational exposure to antineoplastic drugs in Japan, we examined DNA damage, assessed by the comet assay, in 121 female nurses and 46 female clerks working at three hospitals in the northeast of Japan. The comet assay is considered to be a sensitive and rapid method for DNA strand break detection in individual cells, and tail length and tail moment are used as the comet parameters. Concerning the basal characteristics, the 46 control subjects had higher rates of smoking and coffee-drinking habits and lower hemoglobin than the 121 nurses (p<0.05). The log-transformed tail length in the nurses was significantly longer than that in the control subjects after adjusting for possible covariates such as age and smoking habit (p<0.05). Also, the log-transformed tail length was significantly longer, in the 57 nurses who had handled antineoplastic drugs in the last six months, than that in the 46 control subjects (p<0.05); but, no significant difference in tail length or tail moment was seen between the two nurse groups with and without experience of handling hazardous drugs (p>0.05). These results suggest that Japanese nurses who have worked at hospitals using antineoplastic drugs may have a potential risk of DNA damage. To minimize this risk in Japan, use of biological safety cabinet and appropriate protective equipment, in addition to staff education and training, should be implemented in the healthcare environment.

Abstract
The aim of our study was to investigate whether occupational exposure to antineoplastic drugs (AND) resulted in genetic damage, possibly indicative of adverse health effects in the long term. We performed a chromosomal aberrations (CA) analysis in peripheral blood lymphocytes (PBL) of a group of 76 trained nurses occupationally exposed to AND. Furthermore, we analysed whether genetic polymorphisms in four metabolic genes of the glutathione S-transferase (GST) family involved in antineoplastic drugs detoxification (GSTM1, GSTT1, GSTP1, GSTA1) had any effect on the yield of chromosomal aberrations in nurses exposed to antineoplastic agents. The exposed group showed a very significant increase of genetic damage (p<0.0001) potentially indicative of an increased risk of cancer. Unexpectedly, besides the elevated level of chromatid-type aberrations usually related to exposure to chemical agents, we found also severe chromosome damages such as chromosome deletions and dicentric chromosomes, usually related to radiation exposure. No significant association was detected between all GSTs genotypes and chromosome damage. In conclusion, our data show how the occupational exposure to AND is associated to a potential cancer risk, suggesting that current prevention methods do not completely eliminate opportunities for exposure and supporting the need to improve the actual safety practices.

Abstract
The aims of the present study were to clarify the work environment contamination by antineoplastic drugs in a hospital ward and to assess the genotoxic risks to nurses who routinely handle antineoplastic drugs in Japan. The exposed group consisted of 19 female nurses who routinely handled antineoplastic drugs. The control group consisted of 18 female nurses who did not handle antineoplastic drugs in the same hospital as the exposed group. The genotoxicity of the 19 antineoplastic drugs used in the hospital ward and 8 wipe samples of the workbench after handling of antineoplastic drugs were measured using the umu assay. Lymphocyte DNA damage (tail length) was measured with alkaline methods of the single cell gel electrophoresis assay (comet assay). Of the 19 antineoplastic drugs, dacarbazine, bleomycin, daunorubicin, doxorubicin, pirarubicin, carboplatin, cisplatin and etoposide induced genotoxicity. Of the 8 sampling d, the umu activity of the wipe sample was positive on 3 d. Contamination of the workbench was found when the nurses handled more drugs than on other days. The medians of the tail length in the comet assay were 8.5 and 5.1 microm, respectively, for the exposed and control groups, with a significant difference (p=0.004 by Mann-Whitney's U-test). In the present study, the nurses of the exposed group were considered to have been exposed to antineoplastic drugs and lymphocyte DNA damage of the exposed group was suggested to be induced by antineoplastic drugs.

Abstract
The potential health hazards involved with antineoplastic agents have been known for decades. Many anticancer drugs are recognized as carcinogens and genotoxins in experimental assays. Second cancers have been recorded in follow-up studies with treated patients. The first findings on occupational exposures among hospital personnel administering chemotherapy were reported only in 1979. Since that time a magnitude of studies have been published using various chemical and biological exposure measurements. These findings prompted improvements in the handling practices of personnel working with anticancer drugs. In spite of strict guidelines for the safe handling of cancer chemotherapeutic agents and extensive improvements in the handling facilities in hospitals, also recent studies have revealed detectable, even if generally much decreased, amounts of indicator drugs in air and surface wipe samples, also including biological samples of personnel in hospital pharmacies and cancer therapy wards. Follow-up measurements show that application of strict safety precautions in hospitals decreases the biological exposure and/or effect markers to the level of unexposed referents. Open information and constant tutoring of personnel to avoid the hazards when working with anticancer drugs is absolutely necessary with the increasing use of these important drugs.

Abstract
OBJECTIVES This study evaluates by comet assay the induction of early DNA damage in healthcare workers of an oncology hospital regularly handling antineoplastic drug mixtures. The aim was to identify a suitable biomarker of DNA damage by exposure to low levels of such drugs. METHODS We studied 12 day hospital nurses and 13 oncology ward nurses who performed up to 300 and up to 35 drug administrations per week, respectively, and five pharmacy employees who regularly prepared mixtures of antineoplastic agents. Thirty healthy subjects were selected as controls. For exposure evaluation, we performed environmental monitoring of 5-fluorouracil, cytarabine, gemcitabine, cyclophosphamide, and ifosfamide in selected work areas of pharmacy and day hospital units and biological monitoring of urine for the 5-fluorouracile metabolite, alpha-fluoro-beta-alanine. We evaluated early DNA damage in lymphocytes and exfoliated buccal cells by comet assay measuring tail moment (TM) parameter that indirectly indicates the presence of DNA damage. RESULTS Environmental monitoring detected cyclophosphamide, 5-fluorouracil and ifosfamide, with higher levels of contamination in day hospital unit. The biological monitoring measured detectable levels of alpha-fluoro-beta-alanine only in three nurses. Comet assay showed an increase on exfoliated buccal cells, even if not statistically significant, of mean TM with respect to controls in day hospital nurses (43.2 vs. 28.6, respectively) while ward nurses and pharmacy technicians did not show differences. Comet assay performed on lymphocytes did not show appreciable differences between exposed and controls. CONCLUSIONS The employment of the sensitive comet assay, which is able to detect early the effects of a recent exposure to genotoxic substances, allowed us to find a slight DNA damage, only on exfoliated buccal cells of day hospital nurses, the group handling the highest amount of drugs during the administration process. This finding suggests that comet assay on exfoliated buccal cells could represent a useful tool to evaluate early and still repairable genotoxic effects of exposure to antineoplastic drug mixtures and then contribute to the improvement of the hospital safety practices.

Abstract
The continuous introduction of new antineoplastic drugs and their use as complex mixture emphasize the need to carry out correct health risk assessment. The aim of this study was to evaluate genotoxic effects of antineoplastic drugs in nurses (n=25) and pharmacy technicians (n=5) employed in an oncology hospital. The nurses administered antineoplastic drugs in the day-care hospital (n=12) and in the wards (n=13), and pharmacy technicians prepared the drugs in the central pharmacy. We performed the micronucleus (MN) test with lymphocytes and exfoliated buccal cells and conducted traditional analysis of chromosomal aberrations (CA). Thirty healthy subjects were selected as controls. Monitoring of surface contamination with cyclophosphamide, 5-fluorouracil, ifosfamide, cytarabine, and gemcitabine showed the presence of detectable levels only for cyclophosphamide, 5-fluorouracil and ifosfamide. In addition, we measured the 5-fluorouracil metabolite alpha-F-betaalanine in the urine of all subjects and found significant concentrations only in 3 out of 25 nurses. The micronucleus assay with lymphocytes did not show significant differences between exposed and control groups, while the same test with exfoliated buccal cells found higher values in nurses administering antineoplastic drugs than in pharmacy employees. In the CA analysis, we detected in exposed groups a significant increase (about 2.5-fold) of structural CA, particularly breaks (up to 5.0-fold). Our results confirm the genotoxic effect of antineoplastic drugs in circulating blood lymphocytes. Moreover, in exfoliated buccal cells the data show more consistent genetic damage induced during administration of the antineoplastic drugs than during their preparation. The data also stress the use of this non-invasive sampling, to assess occupational exposure to mixture of chemicals at low doses.

Abstract
In Europe and America, many health care workers have concerns about the risks to their health of handling anticancer drugs. The findings of the risks were reported in the late 1970's, and guidelines for the safe handling of anticancer drugs were established in the 1980's. The conditions of wearing personal protective equipment and of the working environment have improved dramatically as a result of introduction of the guidelines. Furthermore, researches and studies into the health effects of occupational exposure to anticancer drugs have been pursued actively. In Japan, the society of hospital pharmacists established guidelines for the safe handling of anticancer drugs in 1991. Since then, mainly nurses have been concerned about the safe handling of anticancer drugs, but in the medical setting, the present situation surrounding the safe handling of anticancer drugs has hardly changed. In the industrial hygiene field, the safe handling and the occupational exposure to anticancer drugs have been seldom reported and researched. The actual potential hazards to occupational exposure of anticancer drugs have not yet been determined. Nevertheless, the reduction of occupational exposure to anticancer drugs in health care workers has been an important challenge for the industrial hygiene field. In Japan, we need to promote action to spread the use of the appropriate personal protective equipment and the appropriate working environment. We also have to rethink the safe handling of anticancer drugs. We hope that the Japanese government will establish an effective authorized guideline as has been done in Europe and America.

Abstract
The Comet assay is a rapid, easy and reproducible method to detect genotoxic activity of chemical and physical agents in vitro and in vivo. In the present study the effects of exposure to irradiation or chemicals: cyclophosphamide (CP) and mitomycin C (MMC) or combined exposure to low doses of both agents (0.25 Gy+3.15 mg/kgbw CP and 0.25 Gy+0.25 mg/kgbw MMC) were examined for the induction of DNA damage in the Comet assay measured simultaneously in somatic (bone marrow lymphocytes) and haploid germ cells. The male mice were treated in vivo and sacrificed at 24 h after exposure. The percentage contents of DNA in the "comet tail" increased with increasing doses of X-rays and chemicals. After combined exposure to X-rays and CP and to X-rays and MMC weak increases of DNA damage in bone marrow lymphocytes and in germ cells were observed by comparison with the results obtained for each agent acting alone. There were slightly different responses in bone marrow lymphocytes and in germ cells, but effects were observed over a similar dose range.

Abstract
In recent years, the potential for exposure of health care workers to antineoplastic agents has led to the establishment of more restrictive government and professional standards and procedures for handling cytotoxic drugs. Therefore, the detection of low exposure levels is a new and important aim of biological monitoring. In the present paper we report an assay for the simultaneous determination of cyclophosphamide (CP) and ifosfamide (IF) in urine, using electrospray ionization liquid chromatography/tandem mass spectrometry with selective reaction monitoring (HPLC/SRM-MS). A rapid sample preparation procedure uses a solid-phase extraction stage with C18 columns. The urine assay is linear over the range 0.02 to 0.4 microg/L, with lower limits of quantification (LLOQs) of 0.02 and 0.04 microg/L for CP and IF. The accuracy and precision have been carried out through the validation study. The intra-day precision, expressed as relative standard deviation (RSD), is found to be always less than 14.7% for both analytes. The overall precision, assessed on three different days, is less than 15.0%. The recovery of ozaxaphosphorines ranges from 83.5% (CP) to 88.5% (IF) with a RSD always less than 14.6%. The uncertainty of the overall method was also evaluated, to identify possible sources of error. The combined uncertainty was less than 25% over all the days of the validation study. This method is selective and sensitive enough to determine trace levels of CP and IF in a range of urine concentrations relevant to performing low exposure assessment.

Abstract
In order to assess occupational exposure of hospital personnel involved in the preparation and administration of antineoplastic drugs, biological and environmental monitoring are essential to identify the main exposure routes and to quantify potential health risks. If workplace contamination cannot be completely avoided, it is of utmost importance to reduce exposure to the lowest possible levels. To this aim, not only do education and training of the exposed subjects play an important role, but accurate standardized sampling techniques and analytical methods are also required. A critical overview of the most significant methods available in the literature is presented and their value is discussed, especially with respect to their sensitivity and specificity. In addition, attention is given to validation procedures and, consequently, to their reliability. The results from the most important surveys carried out at hospital departments are also discussed, with a view to improving both monitoring strategies and moreover working conditions.
