Resting energy expenditure in dogs with nonhematopoietic malignancies before and after excision of tumors.
OBJECTIVE
To determine whether apparently resting dogs with nonhematopoietic malignancies have increased resting energy expenditure (REE), compared with clinically normal dogs.


METHODS
46 client-owned dogs with nonhematopoietic malignancies and 30 client-owned dogs that were clinically normal.


METHODS
Apparently resting, client-owned dogs with nonhematopoietic malignancies before (n = 46) and 4 to 6 weeks after (n = 30) surgical removal of tumors were compared with apparently resting, clinically normal, client owned dogs (n = 30). An open flow indirect calorimetry system was used to determine the following: rate of oxygen consumption (ml/min/kg of body weight); rate of carbon dioxide production (mls/min/kg), REE (kcal/kg/d) and respiratory quotient. Because of the wide range of body weight, REE and oxygen consumption were also expressed per kg of body weight 0.75.


RESULTS
Surgical removal of the tumor did not significantly alter any of the variables measured when all dogs with tumors were assessed as a single group, or when the dogs were divided on the basis of having the following types of tumors: carcinomas and sarcomas, osteosarcomas, and mammary adenocarcinomas. None of the data obtained prior to surgical treatment from any of the dogs grouped by tumor type were significantly different from clinically normal dogs.


CONCLUSIONS
REE (54.4 +/- 16 kcal/kg/d or 125 +/- 19 kcal/kg0.75/d) and, presumably, caloric requirements of dogs with nonhematopoietic malignancies are not significantly different from those obtained from clinically normal dogs (53.9 +/- 16 kcal/kg/d or 116 +/- 32 kcal/kg0.75/d). Furthermore, these variables do not change significantly when the tumor is excised and the dog is reassessed after 4 to 6 weeks.


CONCLUSIONS
Knowledge that REE in dogs with solid tumors is not significantly different from REE of clinically normal dogs may be of value when planning nutritional treatment for dogs with nonhematopoietic malignancies.
