Tumours in 177 pet hamsters

Abstract

Background: Even though tumours are considered to occur frequently in pet hamsters, there is only a small number of scientific reports in current literature.

Methods: Pathological reports from 177 hamsters were evaluated.

Results: Of these, 78 were male and 75 were female. Median age of affected hamsters was 12 months (range 2-34). Integumental tumours were the most common neoplasms (62%, 109/177). As far as species was known, the number of Syrian hamsters (52%, 30/58) affected by tumours seemed to be lower than the number of affected dwarf hamsters (85%, 47/55). Tumours of the hematopoietic system were the second most frequently neoplasms (17%, 30/177). Relative number of neoplasms of the endocrine system, tumours of the digestive system (1.7%, 3/177) and other tumours (4%, 7/177 each) was low. The majority of integumental tumours were epithelial (66%; 91/126).

Conclusion: This study aimed to analyze data from veterinary surgeries and pathological institutes about the occurrence of spontaneous tumours in Syrian hamsters and dwarf hamsters to give information about the frequency of tumours, prognosis and survival time. This is the first study about tumours in pet hamsters in Germany so far.

Keywords: Syrian hamster; dwarf hamster; neoplasms; small mammals.
