Summary of "Correlation Between Body Weight and Mitoxantrone-Associated Neutropenia in Dogs."

Thirty-seven dogs with histologically or cytologically confirmed malignant tumors treated with single-agent mitoxantrone at 5 mg/mwere evaluated in a retrospective study assessing the correlation between body weight and neutropenia associated with a single dose of mitoxantrone in dogs. Overall, eight dogs (21%) experienced grade 3 neutropenia and five dogs (14%) experienced grade 4 neutropenia on day 7 following mitoxantrone chemotherapy. Dogs ≤10 kg body weight were significantly more likely to develop grade 3 or 4 neutropenia (5.8 relative risk; 95% confidence interval, 2.6-12.9; P < .0001) than dogs >10 kg. Dogs ≤15 kg body weight were significantly more likely to develop grade 3 or 4 neutropenia (8.1 relative risk; 95% confidence interval, 2.1-31.3; P < .0001) than dogs >15 kg. Of the 13 patients who developed grade 3 or 4 neutropenia, 6 (46%) were hospitalized for clinical signs related to neutropenia. Based on the severity of neutropenia and the resulting hospitalization seen in dogs ≤10 kg, a dose reduction could be considered for the initial dose of mitoxantrone, and clinicians should be aware of the increased risk of neutropenia in patients 10.1 to ≤15 kg.

Medical and Biotech [MESH] Definitions

Sustaining BODY WEIGHT after BODY WEIGHT CHANGES have been achieved.

Expected weight of a healthy normal individual based on age, sex, and height. Thus, a malnourished person would weigh less than their ideal body weight.

An indicator of body density as determined by the relationship of BODY WEIGHT to BODY HEIGHT. BMI=weight (kg)/height squared (m2). BMI correlates with body fat (ADIPOSE TISSUE). Their relationship varies with age and gender. For adults, BMI falls into these categories: below 18.5 (underweight); 18.5-24.9 (normal); 25.0-29.9 (overweight); 30.0 and above (obese). (National Center for Health Statistics, Centers for Disease Control and Prevention)

A status with BODY WEIGHT that is above certain standard of acceptable or desirable weight. In the scale of BODY MASS INDEX, overweight is defined as having a BMI of 25.0-29.9 kg/m2. Overweight may or may not be due to increases in body fat (ADIPOSE TISSUE), hence overweight does not equal "over fat".

Increase in BODY WEIGHT over existing weight.
