As relevant information, positive results are also reported in other in vivo tests (mouse spermatogonium and spermatocyte chromosomal aberration tests, mouse bone marrow and embryo and rabbit peripheral lymphocytes chromosomal aberration tests, rat and mouse bone marrow micronucleus tests) (IARC vol. 50 (1990)). From in vitro mutagenicity tests, there are reports of positive Ames tests, chromosomal aberration tests and sister chromatid exchange tests (NTP DB (access on Oct, 2009), IARC vol. 50 (1990)).

Based on the classification of Group 1 by IARC (IARC vol. 50 (1990)) and classification of K by NTP (NTP ROC 11th, 2004)), the substance was classified as Category 1A. Several cases of leukaemia following treatment with this substance alone have been reported. One case-control study showed a strong association between risk for leukaemia and treatment with this substance. Additionally, in animal studies by intraperitonela administration, an increased incidence of lung tumours and lymphoproliferative malignancies was observed in mice of both sex, and an increased incidence of lymphoproliferative malignancies in male rats and of uterine adenocarcinomas and mammary carcinomas in female rats was observed (IARC vol. 50 (1990)).

The substance suppresses the bone marrow in humans (IARC vol. 50 (1990)). From information under the Adverse Reactions section of the package insert of Thiotepa, there are the following reports; leukopenia, thrombocytopenia, hemorrhage, anemia, renal failure, shock, hypogammaglobulinemia, hepatic disorder, anorexia, nausea, vomiting, diarrhea, stomatitis, diarrhea, dry mouth, abdominal pain, rash, malaise, headache, pharyngeal pain, increased bloody sputum, difficulty in urination, frequent urination, cystitis, fever, and alopecia. Since it is unclear whether these are acute effects, the substance was classified into Category 2 (systemic toxicity). As information in a document in List 3, there are the following reports: paresthesia, changes in bone marrow (not specified) in human treated parenterally (RTECS (2009): Cancer. Vol. 38, p. 1471, 1976); and flaccid paralysis (neuromuscular blockage), somnolence, ataxia at 38 mg/kg (LD50 value) in a mouse oral test (RTECS (2009): Imifos, Giller, S.A., ed., Izd, Riga, USSR, p. 129, 1968).

From information under the Adverse Reactions section of the package insert of Thiotepa, there are the following reports; significant adverse reactions: leukopenia, thrombocytopenia, hemorrhage, anemia, renal failure, and shock. Based on the data, the substance was classified into Category 1 (bone marrow, lung, systemic toxicity). In addition, there are the following reports; other adverse reactions: hypogammaglobulinemia, hepatic disorder, anorexia, nausea, vomiting, diarrhea, stomatitis, diarrhea, dry mouth, abdominal pain, rash, malaise, headache, pharyngeal pain, increased bloody sputum, difficulty in urination, frequent urination, cystitis, fever, and alopecia. No data with oral, dermal or inhalation routes are available for human or animals. The substance suppresses the bone marrow in humans and was used in the treatment of tumours (IARC vol. 50 (1990)). There is a report that the toxic effect is myelosuppression, characterized by granulocytopenia and thrombocytopenia; disturbances in hepatic and renal function, neurotoxicity, nausea and vomiting were uncommon (IARC vol. 50 (1990)).
