The use of traditional chemotherapy agents is being revisited through novel methods or schedules of administration.
Palladia, the first drug officially approved for use in treating dog cancer has arrived. Yunnan Baiyao is a hemostatic powdered alternative medicine used anecdotally to decrease hemorrhage. Studies of splenic and hepatic lesions have shown that MRI and CT carry a high sensitivity and specificity in determining benign from malignant processes. June 22, 2016 – Hemangiosarcoma is a cancer dreaded by all golden retriever owners and veterinarians. The development of noninvasive biomarkers with specificity to HSA would be clinically useful for not only early detection and treatment but also to monitor for progression of disease. Serum TK1 activity was significantly higher in dogs with HSA than in normal dogs.
An aggressive protocol combining dacarbazine, DOX and vincristine (DAV protocol) was evaluated in 24 dogs with advanced-stage inoperable HSA and showed a response rate approaching 50%, including five complete and four partial responses, for a median time to tumor progression or 101 days and a reported MST of 125 days.Since the combination of traditional therapeutic modalities has reached a plateau unlikely to be surpassed, with median survival times averaging 6-7 months, new therapies are impatiently awaited. I’m very grateful! In the patients receiving the high dose (n=5), a median survival of 112 days was noted. The authors have recently completed a large study evaluating the addition of a metronomic protocol to standard doxorubicin.Polysaccharopeptide (PSP), the bioactive agent of the mushroom Coriolus versicolor(aka Cloud mushroom, turkey tail, or Yunzhi mushroom) was evaluated in a small study of 15 dogs receiving three dosings. Hemangiosarcoma.
Evaluation of a fragment of collagen XXVII noted high concentrations in serum of dogs diagnosed with advanced stage HSA. Hemangiosarcoma (HSA) is a highly malignant tumor of endothelial cells and is diagnosed more frequently in dogs than in any other domestic species. Differences between HSA cells and non-malignant endothelial cells in regards to increased expression of genes involved in inflammation, angiogenesis, adhesion, invasion, metabolism, cell cycle, signaling, and patterning have been documented. Even though a prospective evaluation of TK1 in 62 dogs with hemoabdomen due to benign splenic masses or HSA was unable to distinguish between the two, the ability to discriminate between the two became significant when a specific two tiered cut off system was implemented, making TK1 an attractive biomarker.Traditional therapy for HSA, as for other cancers, involves surgery, radiation therapy, and systemic cytotoxic chemotherapy, alone or in a multimodality setting.Conventional chemotherapy also has been evaluated with macroscopic HSA. Provisional diagnosis osteosarcoma on 6/10/10, amputation of left foreleg same day, firm diagnosis of hemangiosarcoma 6/24/10.
Now it’s finally ready for release. The skin form of hemangiosarcoma is the best type to have as it is the most easily removed surgically and thus has the greatest potential for complete cure. However, there are ways to prolong your dog's life using different treatments. Set free on 9/9/10. For cardiac HSA, cardiac troponin I (cTnI) has proven to be a highly specific and sensitive marker for myocardial cellular damage in many mammalian species. She said basically that we could try metronomics or palladia, but that she didn’t go so far as to actually recommend it. This was described in the Dog Cancer Survival Guide by it’s pre-market name, SU11654. Thymidine kinase (TK) is a cytosolic enzyme whose activity is closely correlated with the DNA synthesis and its expression is generally restricted to proliferating cells.
Furthermore, the increased sensitivity of thoracic CT for early pulmonary metastasis detection has been reported.
A lightning bolt and rolling thunder that comes from nowhere on a day that was filled with blue skies only moments ago. By so doing, the common problems of toxicities and drug resistance can be largely avoided. The daily administration of low doses (metronomic dosing) of traditional cytotoxic chemotherapy agents is another new approach. June 22, 2016. A recent study evaluating Toceranib (Palladia; Zoetis) in dogs with splenic HSA following surgery and standard doxorubicin therapy noted no significant improvement in overall survival.
With the increasing use of such diagnostic techniques in veterinary medicine, they are gradually incorporated in the thorough staging of dogs with HSA.The definitive diagnosis of HSA is obtained with histopathology and this generally obtain via surgery.
