Cancer in dogs
Treatment options vary and depend on the type and stage of cancer. Common treatments include surgery, chemotherapy, radiation therapy, amputation, and immunotherapy. A combination of therapies may be used. Knowledge and treatment of cancer have increased significantly in the past three decades. Survival rates have also increased due to the increase prevalence of canine cancer treatment centers and breakthroughs in targeted drug development. Canine cancer treatment has become an accepted clinical practice and access to treatment for owners has widely expanded recently. Cancer-targeting drugs most commonly function to inhibit excessive cell proliferation by attacking the replicating cells. However, there is still a prevalent pharmacy gap in veterinary oncology.
Autologous immune enhancement therapy
Adoptive Immuno cell therapy of cancer was first introduced by Steven Rosenberg and his colleagues of National Institute of Health USA. In the late 80s, they published an article in which they reported a low tumor regression rate (2.6–3.3%) in 1205 patients with metastatic cancer who underwent different types of active specific immunotherapy (ASI), and they suggest that AIET with specific chemotherapy or radiotherapy as the future of cancer immunotherapy. In the beginning Immunotherapy treatments involved administration of cytokines such as Interleukin. with an aim of inducing the lymphocytes which will carry their activity of destroying the tumour cells. Thereafter the adverse effects of such intravenously administered cytokines lead to the extraction of the lymphocytes from the blood and culture-expand them in the lab and then to inject the cells alone enable them destroy the cancer cells. Till date different kinds of autologous and allogenic immune cells such as lymphokine-activated killer(LAK)cells, Natural killer (NK) cells, Activated Cytotoxic T lymphocytes(CTLs), Dendritic cells(DCs), Gene manipulated autologous and allogenic Immune cells have been used in clinical applications of Immunotherapy.
