The most common areas for osteosarcomas in dogs are the radius/ulna above the carpus (front knee/wrist) and the tibia/fibula below the stifle/knee), but osteosarcoma of the digits (toes), femur (above the stifle), and hip occur as well. How is osteosarcoma diagnosed? Most dogs with osteosarcoma will limp on the affected limb.

Osteosarcoma (OSA) is one of the most common types of bone cancer in dogs, often diagnosed in large or giant breed dogs, such as Rottweilers, Great Danes, St. Bernards, and Golden Retrievers. The tumor commonly grows on the long bones of the forelimbs or hindlimbs, causing pain and lameness.

A combination of amputation and chemotherapy is the current standard of care for dogs with OSA. In addition to the previously mentioned contraindications for limb amputation, the toxicity of each chemotherapy agent must be considered in light of the dog's organ function and …

Osteosarcoma (OSA) is an aggressive primary bone tumor in the domestic dog that most often occurs within the appendicular skeleton. Despite the use of adjuvant chemotherapy, most dogs succumb to metastatic disease within 1 year of diagnosis. To improve this outcome, substantial research is currently focused on investigating novel therapies.

Osteosarcoma (OSA) is the most common type of bone tumors in dogs, which has high metastasis ability. 80 % of dogs with OSA die due to lung metastasis. As a result its treatment is a challenge for veterinary practitioners. The authors discuss the etiology, pathogenesis and the possible risk factors of OSA.

Osteosarcoma (OS) is the most common primary bone tumor found in dogs. It accounts for up to 85% of all malignancies originating in the skeleton. It mostly occurs in middle-aged to older dogs, with a median age of 7 years. Primary rib OS tends to occur in younger adult dogs with a median age of 4.5 to 5.4 years.

Part 1 of this 2-part series on canine osteosarcoma provides a general overview, history, and diagnosis of the disease. Part 2 will describe treatment and follow-up protocols. Osteosarcoma (OSA), a primary bone tumor comprised of neoplastic osteoblasts, can cause pain and lameness in affected limb (s) (Figure 1).*

Osteosarcoma (OSA) is the most common primary bone tumor in dogs and cats. Approximately 80-85% of all canine skeletal tumors are diagnosed as osteosarcomas. Although the exact etiology is unknown, there has been some evidence that derangement of bone growth or differentiation of new bone at the long bone metaphyses may be to blame.

OSA is the most common primary bone tumor in dogs (85%) and cats (70%) (Dernell et al., 2001; Thompson et al., 2017). OSA occurs with highest frequency in large or giant-breed dogs (77.8%) (Withrow et al., 1991; Tuohy et al., 2019; Dernell et al., 2001; Ru et al., 1998; (Edmunds et al., 2021)) with dogs <15 data-preserve-html-node="true" kg ...

2011年9月1日 · Osteosarcoma (OSA) is the most common primary bone tumour in dogs. The appendicular locations are most frequently involved and large to giant breed dogs are commonly affected, with a median age of 7–8 years. OSA is a locally invasive neoplasm with a high rate of metastasis, mostly to the lungs.
