4 doses), administration with cyclophosphamide.Maropitant: 1 mg/kg s.c. once is given before doxorubicin/epirubicinFurosemide: 1 mg/kg p.o. J Vet Intern Med 4:187, 1990 Doxorubicin/epirubicin can cause cardiotoxicity (arrythmia if given too quickly or systolic dysfunction at high cumulative doses (>180 mg/mTreatment can be given if the neutrophil count is > 3 × 10Remission: Attaining complete remission is an important prognostic indicator (especially in cats). Only veterinarians who examine your dog can give you veterinary advice or diagnose you or your dog’s medical problem. Vincristine is a vesicant, therefore catheters should be placed in all cases and only catheters placed by ‘first-stick’ should be used. 0000004970 00000 n
Subsequent remissions can be more difficult to achieve as well as being shorter in duration. Van Vechten M, Helfand SC, Jeglum KA. Should an extravasation occur, contact an oncologist. 0000008873 00000 n
Relapse: If a patient completes treatment in remission, they should be monitored monthly. Prednisone is capable of upregulating p-glycoprotein, which may explain the decreased response rates in those patients pre-treated with steroids. There are multiple mechanisms that can convey drug resistance and, for many drugs, there is more than one mechanism that can induce resistance (Table 1). q24h (week 2), 1 mg/kg p.o. CCNU can cause hepatoxicity, so periodic evaluation of liver enzymes is advised. 0000001284 00000 n
Short-term protocols have the advantages of being less expensive, requiring fewer visits and potentially having fewer side effects. If blood is noted, suspend cyclophosphamide and culture urine. J Vet Intern Med 16:576, 2002. 0000004561 00000 n
For dogs t treated with a CHOP-L type of protocol and then taken off treatment for a while, an effective strategy may be re-induction with a similar CHOP-L protocol. 0000010671 00000 n

Three examples are provided below.Note that oral cytotoxic drugs cannot be split or divided and should not be crushed. One study has reported that the response of canine subjects with MDR lymphoma to CCNU lasted for a median of 86 days . 0000027712 00000 n
Which Drugs Are Used for Medical when added to a standard CHOP protocol for dogs with lymphoma? 4 doses), administration with cyclophosphamideMaropitant: 1 mg/kg s.c. once ais given before doxorubicin/epirubicinFurosemide: 1 mg/kg p.o. However, resistance to vincristine or prednisone also may confer resistance to doxorubicin or actinomycin-D, due to up-regulation of P-glycoprotein. Cimetidine is avoided due to its effect on the hepatic cytochrome P450 enzyme pathway and the potential for altering metabolism of chemotherapeutics.• Certain breeds (generally Collie type) are very sensitive to vincristine due to the • Most oncologists prefer a CHOP type, but high dose COP is a useful and relatively straightforward protocol for use in a non-specialist setting.• Haematology should be checked prior to each vincristine treatment. Different applications would include localized or regional radiation therapy, half-body radiation therapy or total-body irradiation (TBI). If blood is noted, suspend cyclophosphamide and culture urine. With standard CHOP-L protocols (those that include L'asparaginase, vincristine, cyclosphosphamide, doxorubicin and prednisone), reported first-remission rates are 80 percent to 90 percent, with the average first remission between eight and 12 months. MOPP chemotherapy for treatment of resistant lymphoma in dogs: a retrospective study of 117 cases (1989-2000). 4 doses), administration with cyclophosphamide.Maropitant: 1 mg/kg s.c. once is given before doxorubicin/epirubicinFurosemide: 1 mg/kg p.o.
