Even with Cytoxan we are still guessing in terms of tumor types, drug schedules, monitoring response, etc. There is very little known about metronomic (anti-angiogenic) chemotherapy using Chlorambucil (same thing as Leukeran). Maybe Dr. Biller would co sider followi g Sassy, Jackson and Jill as they certai lh are a “study group” right here in tripawd land.
No data for Alkeran as a metronomic agent exists that I am aware of.Obviously Cytoxan because there is human and dog data to tell us that it is anti-angiogenic when used in a metronomic fashion. This is commonly executed using a combination of cyclophosphamide (cytoxan) and piroxicam, however several other protocols have been published, including chlorambucil, etoposide and thalidomide. Splenic hemangiosarcoma is a malignant neoplasm of vascular endothelial origin which occurs more frequently in dogs than in any other species 1.It is diagnosed in middle aged to older dogs with the following breeds over-represented in published studies: German Shepherds, Golden Retrievers, Labrador Retrievers 1.. Increasing evidence suggests that dysregulation of molecular pathways … Must get another donation to you ASAP!Thank you for providing a great article and answering some of our questions.Log in or register now to get the most benefit from this site.

It has side effects -biggest problem is bone marrow suppression when used for more than a month or two. However, higher cumulative doses of Cytoxan have been associated with an increased risk of developing sterile hemorrhagic cystitis (SHC), which has been reported in 3.6 – 32% of dogs receiving metronomic cytoxan. In contrast to more traditional chemotherapy administered at maximally tolerated doses (MTD), the anticipated outcome with metronomic chemotherapy is disease stabilization or dormancy, therefore it is often pursued as a maintenance therapy, following surgery and/or MTD chemotherapy.Metronomic chemotherapy is well tolerated with minimal risk for bone marrow suppression or gastrointestinal (GI) upset. Acrolein, a breakdown product of cyclophosphamide, is known to irritate the bladder epithelium.
