In total, 250 male animals and 250 female animals in three carcinogenicity studies were analyzed as well as the results of a 6-month study (fifty males and fifty females) and a 12-month study (fifty males and fifty females). In the 24-month studies, in the male animals, twenty-five organs were affected with malignant and benign tumors. In the female animals, twenty-four organs were affected with malignant and benign tumors. The most frequently affected tissue in the three 24-month studies was the adrenal gland where 141 cortical adenomas (56.4%) were noted in 250 male animals and 115 cortical adenomas (46%) noted in 250 female animals. In addition, a high incidence of squamous cell papilloma in the vagina was noted in female hamsters on the 24-month studies. A moderate incidence of squamous cell papilloma of the nonglandular forestomach, benign granulosa cell tumor of the ovary, lymphoma of the hemopoietic system, endometrial stromal polyp, and adenocarcinoma of the uterus and islet cell adenoma of the pancreas were also observed on the 24-month studies.<\/jats:p>","DOI":"10.1177\/0192623312448938","type":"journal-article","created":{"date-parts":[[2012,6,17]],"date-time":"2012-06-17T17:34:56Z","timestamp":1339954496000},"page":"86-97","update-policy":"https:\/\/doi.org\/10.1177\/sage-journals-update-policy","source":"Crossref","is-referenced-by-count":20,"title":["Spontaneous Neoplastic Lesions in Control Syrian Hamsters in 6-, 12-, and 24-Month Short-Term and Carcinogenicity Studies"],"prefix":"10.1177","volume":"41","author":[{"given":"Elizabeth F.","family":"McInnes","sequence":"first","affiliation":[{"name":"Healthscope, Glenside, South Australia"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Heinrich","family":"Ernst","sequence":"additional","affiliation":[{"name":"Fraunhofer Institute for Toxicology and Experimental Medicine (ITEM), Hannover, Germany"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Paul-Georg","family":"Germann","sequence":"additional","affiliation":[{"name":"Nycomed GmbH, Konstanz, Germany"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"179","published-online":{"date-parts":[[2012,6,15]]},"reference":[{"key":"bibr1-0192623312448938","first-page":"383","volume":"44","author":"Adaska J.
