Postoperative hypofractionated radiotherapy was given to 14 canine cases with soft tissue sarcomas of limbs, and treatment outcomes and radiation injury were retrospectively analyzed in cases followed-up for 1 year or longer after the termination of the therapy. The recurrence rate was 7.1% and various degrees of radiation injury were observed in 85.7% , but no severe injury has been observed to date. The 1-, 2-, and 3-year survival rates were 100, 92.9, and 66.7% , respectively. The tumor control rates were 85.7, 71.4, and 57.1% , after 1, 2 and 3 years, respectively. The overall treatment outcomes of postoperative hypofractionated radiotherapy for canine soft tissue sarcomas in limbs were similar to conventinal radiotherapy, but not enough for small cases. Hypofractionation appears to be a useful irradiation method for reducing the risk of anesthesia and burden on the animal and owner.

In human lung cancers, marked leukocytosis, especially with neutrophilia and monocytosis, has been reported as a paraneoplastic syndrome. In dogs, several reports have been published on paraneoplastic leukocytosis. In this case, various examinations were conducted on a dog with extreme neutrophilic leukocytosis diagnosed via a blood test at first admission. A huge pulmonary mass was detected, which was surgically removed. The tumor was diagnosed as papillary adenocarcinoma of the lung by histopathology. The number of neutrophils recovered to normal after surgery, and the dog was diagnosed as paraneoplastic syndrome due to lung cancer.
