Which tumor has approximately a 90% curative rate when treated with chemotherapy?

• A. Osteosarcoma
• B. TVT (transmissible venereal tumor)
• C. Lymphoma
• D. Melanoma

Answer: (B)

Chemosensitivity varies widely among tumors, and this particular one is known for its exceptional response to chemotherapy. Transmissible venereal tumor in dogs typically shows dramatic shrinkage and is often completely cured with a standard chemotherapy approach, with cure rates around 90% or higher. This high success is due to the tumor’s biology, which makes it highly susceptible to agents like vincristine, and it often regresses quickly with treatment. In contrast, osteosarcoma usually requires aggressive local control (surgery) plus chemotherapy, and cure rates with chemo alone are not that high. Lymphoma can respond very well to chemotherapy and produce long remissions, but a guaranteed cure rate near 90% across all cases isn’t as consistent. Melanoma tends to be more chemo-resistant, with lower cure rates from chemotherapy alone.
