50 Chronic infections with the flatworm parasites Opisthorchis viverrini, Clonorchis sinensis and 51 Schistosoma haematobium are classified as group 1 biological carcinogens, i.e. definitive causes 52 of cancer. In addition, we reported findings that support the inclusion of Opisthorchis felineus in 53 this list of biological carcinogens. By contrast, infections with close phylogenetic relatives 54 including Fasciola hepatica have not been associated with carcinogenesis. Earlier reports revealed 55 of oxysterol metabolites of Opisthorchis liver fluke origin conjugated with DNA bases, suggesting 56 that the generation of these DNA-adducts may underlie the mutagenicity and carcinogenicity of 57 the infection with these food-borne pathogens. Here we employed liquid chromatography-mass 58 spectrometry (LC-MS/MS) to investigate, compare and contrast spectrograms of soluble extracts 59 from F. hepatica adult worms from bile ducts of cattle with those from O. viverrini and O. felineus 60 from experimentally-infected hamsters. F. hepatica displayed a complex spectrophotometric 61 profile. F. hepatica and Opisthorchis spp. shared several common compounds including oxysterol-62 like metabolites, bile acids and DNA-adducts, but the spectrometric profiles of these Opisthorchis 63 species included far fewer compounds than F. hepatica. These findings support the postulate that 64 oxysterol-like metabolites of parasite origin can initiate carcinogenesis and they point to a 65 molecular basis for the inconsistencies among major groups of liver flukes concerning infection-66 induced malignancy. 67 (202 words) 68 69 70 71 72 73 4 74 Author Summary 75 Several species of trematodes are parasites of the human hepatobiliary tract. Infection with 76 two of these flukes, Clonorchis sinsensis and Opisthorchis viverrini, fresh water fish-borne 77 parasites that occur in East Asia is classified as group 1 carcinogens by the International Agency 78 for Research on Cancer (IARC), i.e. definitive causes of cancer in humans. By contrast, infection 79 with a different liver fluke, Fasciola hepatica, does not lead to malignant transformation of the 80 biliary tract. Given the close phylogeny of all three parasites, this difference in carcinogenicity is 81 intriguing and, if explained, likely of value in novel therapeutic approaches. The importance of the 82 current findings is informative because they present a mass spectrometric analysis and catalog of 83 the similarities and differences between fluke of the genus Opisthorchis and F. hepatica, 84 potentially identifying carcinogenic metabolites of liver fluke origin. These metabolites can be 85 expected to provide deeper understanding of helminth infection induced malignancy. 86 (149 words) 87 88 89 90 91 92 Keywords 93 Fasciola hepatica, Opisthorchis viverrini; Opisthorchis felineus; oxysterols; DNA adducts 94 95 5 96 97 More than 20% of cancer in the developing world are caused by infections [1].

“…Opisthorchis felineus infection results in CCC in experimental animals if it is accompanied by a chemical carcinogen (e.g., diethylnitrosamine or dimethylnitrosamine). It has been shown that histopathological features of CCC appear in the liver of the hamsters at 18 weeks postinfection [35]. In one study, after 26 weeks, in three of six hamsters, a mass-forming CCC was found, and after 30 weeks postinfection, CCC was detected in all the hamsters [35].…”

Opisthorchiasis caused by the liver fluke Opisthorchis felineus is one of the most common helminthic infections in the Russian Federation. The largest area affected by opisthorchiasis felinea occupies almost the entire territory of Western Siberia and extends to northern Kazakhstan and a part of the Ural region. Natural endemic regions of opisthorchiasis also exist in the European part of Russia, and in the regions of Western and Eastern Europe. According to the official statistics of the Russian Federation, up to 40 000 patients with opisthorchiasis are registered annually in the country. Opisthorchiasis felinea affects the hepatobiliary system and causes serious liver disorders, including cancer of the biliary tract. Other parasitoses, opisthorchiasis viverrini and clonorchiasis, are widespread in the Southeast Asia and China. The causative agents of these diseases, liver flukes O. viverrini and Clonorchis sinensis, are officially recognized as Group 1 biological carcinogens and are classified as the main risk factors for cholangiocarcinoma. O. felineus is included in Group 3 of biological carcinogens and is not officially considered carcinogenic to humans. Studies on the carcinogenic potential of this liver fluke and the epidemiology of cholangiocarcinoma in the Russian Federation have started in earnest quite recently. Nevertheless, we have some evidence that infection with O. felineus leads to a precancerous state of the bile duct epithelium. This state, combined with additional risk factors, poses a real risk of cholangiocarcinoma. In our opinion, taking into consideration the accumulated facts, the classification of the carcinogenic potential of O. felineus requires revision. In this review, we focus on the relevant characteristics of the biology and epidemiology of this helminth as well as experimental data on opisthorchiasis felinea; this information might clarify the carcinogenicity of O. felineus to humans.
