Anesthesia in domestic animals (small mammals, psittacines and reptiles)

Kandang Kerbau Hospital saw 165 new cases of uterine cancers over the 4-year period from 1991 to 1994. The median age of presentation was 54.1 years and 10.9% of these cases occurred in those aged less than 40 years, unlike the corresponding figures of 61 years and less than 5%, respectively, which are often quoted for endometrial cancers in standard textbooks. Endometrioid adenocarcinoma was the commonest type of uterine cancer seen in our population (75.2%) as in other series. However, we had fewer cases of adenoacanthoma (1.4%) and adenosquamous carcinoma (1.4%) but more cases of uterine sarcoma (11.5%) than is usually reported. 6.7% of our patients had papillary serous adenocarcinoma and 3.0% had clear cell carcinoma. These 2 sub-types are associated with poorer prognosis and there is a need to increase awareness of their existence in our local population as their management differs from that for the usual endometrioid adenocarcinoma. We had fewer patients with stage I disease (53.3%) but more patients with stage III disease (22.4%). This is most likely due to the use of surgico-pathological staging currently as opposed to the clinical staging used previously which led to the under-staging of a proportion of patients.
