Spontaneous endometrial tumours of 'Sabra' rats.
In a 2 year study of 171 female (101 virgin; 70 multiparous) 'Sabra' rats, spontaneous endometrial tumours were found in 69% of 2 year old animals. Tumour development appeared to be age related, and only virgin females showed tumours before 18 months of age. Polyps were the most prevalent tumour type, followed by adenocarcinomas. The Sabra rat can be included among those rat strains having a high incidence of spontaneous endometrial neoplasia.
