Holliday, Aloha Medicinals Inc., 2300 Arrowhead Dr., Carson City, NV 89706, USA; ABSTRACT: Chemotherapy is one of the most common treatments for canine cancer, although it is
frequently quite toxic and can result in disruptions of the dog's normal biochemical and physiological
cycles. Chemotherapy is known to often drive the dog's white blood cell count down (neutropenia),
causing the immune system to weaken and raising susceptibility to opportunistic infections. This often
causes chemotherapy schedules to be interrupted, resulting in less-effi cacious treatment. Neutropenic
patients are commonly symptomatic, exhibiting such side effects as anorexia, diarrhea, vomiting, fever,
and death. Historically, neutropenia is one of the main factors considered in directing chemotherapy
cycles. This study was conducted to determine the effectiveness of a popular mushroom-based vet-
erinary immune-enhancement supplement, K-9 Immunity™, and its adjunct K-9 Transfer Factor™,
when used concurrently with chemotherapy. The objectives of this study were several: to determine if
immune supplementation could reduce neutropenia when partnered with chemotherapy, to determine if
the incidence of side effects would be reduced, and to determine the overall effect on quality of life in
the face of the chemotherapy. In addition to their regularly prescribed cancer treatments and medicines,
dogs in this study received a daily dose of nonspecifi c immune-enhancement supplements: one 500 mg
capsule per 4.5 kg body weight per day of K-9 Immunity™ and one 3000 mg wafer per day (for dogs
greater than 11 kg) or 1/2 wafer per day (for dogs under 11 kg) of K-9 Transfer Factor™. Four different
cancer types were tracked and evaluated in this study: lymphosarcoma (LSA) (N = 21), osteosarcoma
(OSA) (N = 20), mast cell tumor (MCT) (N = 19), and hemangiosarcoma (HSA) (N = 4). Various
chemotherapy or palliative therapy protocols were used according to tumor type and patient suitability.
Standard chemotherapy protocols were followed throughout the study, so long as biological parameters
were found to be within the normal ranges. Blood parameters monitored included CBC, chemistry panel,
and urinalysis, as well as radiographs and other tests per individual protocol. All patients remained in
their homes with clients who were asked to make daily assessments of appetite, attitude, vomiting, diar-
rhea, diet, medications, and other supplements, by way of a questionnaire. Patients were brought to the
clinic routinely for assessment by the veterinary staff and received treatment as prescribed. The results
of this study indicate that as an adjunct to chemotherapy, these supplements do reduce the common side
effects for dogs who become neutropenic. The study also showed that this type of immune-modulation
therapy relieves many of the symptoms usually associated with chemotherapy and allowed the dogs to
maintain a quality of life more closely related to their norm. These results indicate that further research
into nonspecifi c immune-modulation therapy as an adjunct to chemotherapy is warranted, with the goal
of improving the quality of care and quality of life that we can deliver to our canine cancer patients.
