Lomustine is used as an "off-label" veterinary treatment for cancers in cats and dogs. [5] Clinical trials have demonstrated the drug's success in treating progressive lymphomas, mast cell tumors, and brain cancers. [11] [12] The chemotherapy has also been used to treat sarcomas and spinal cord tumors in these animals. [5]
The average survival times of dogs treated with prednisone and untreated dogs are both one to two months. [1] Using prednisone alone can cause the cancer to become resistant to other chemotherapy agents, so it should only be used if more aggressive treatment is not an option. Isotretinoin can be used to treat cutaneous lymphoma. [8]
The immediate complete response rate was in the 75% range in Nigro's original reports. Response to treatment can be evaluated every 6-8 weeks for many months if disease is regressing or clinically stable. Any sign of progressive disease should prompt reassessment of disease with biopsy and subsequent surgery with the aforementioned APR. [6]
There are three main treatment options available to treat soft tissue sarcoma in cats and dogs: surgery, radiation therapy, and chemotherapy. Surgery alone or in combination with radiation therapy are used to treat the tumor at its original location, and chemotherapy is usually used to prevent or at least slow down the process of metastasis in ...
The prognosis for complete remission with chemotherapy is excellent. [20] The most common chemotherapy agents used are vincristine, vinblastine, and doxorubicin. [14] Use of autohaemotherapy in treatment of TVTs also showed promising results in many cases. [21] Radiotherapy may be required if chemotherapy does not work. [17]
For inoperable tumors, treatment with tyrosine kinase inhibitors may be attempted. In general, the prospect of cure is best in well-differentiated mastocytomas (low-grade or grade 1) and in animals without general signs (substages a). [18] Young dogs (<1 year of age) also have a better prognosis than older dogs. [29]
MOPP was the first combination chemotherapy brought in that achieved a high success rate. It was developed at the National Cancer Institute in the 1960s by a team that included Vincent DeVita, Jr. Although no longer the most effective combination, MOPP is still used after relapse or where the patient has certain allergies or lung or heart ...
The word chemotherapy without a modifier usually refers to cancer treatment, but its historical meaning was broader. The term was coined in the early 1900s by Paul Ehrlich as meaning any use of chemicals to treat any disease (chemo-+ -therapy), such as the use of antibiotics (antibacterial chemotherapy). [194]
