Despite the rather small sample size, we were able to observe a large spectrum of variable responses to oncolytic virus therapy. Male dog of mixed breed of 7 years old was presented with cutaneous, ulcerated, and poorly differentiated mastocytoma (35 mm diameter) located near his anus. (1990) 50:1299307. doi: 10.1007/s10719-006-5433-0. Each application of Sendai virus (107-108.6 EID50) consisted of multiple individual 0.010.1 ml injections delivered intratumorally, intradermally around a tumor, and under a tumor bed. Ammendola M, Sacco R, Sammarco G, Luposella M, Patruno R, Gadaleta CD, et al. A diagnosis can be scary, but the good news is that treatment options are available for your pet. The radiation delivered to the tumor can damage the normal, healthy tissue surrounding it. This freeze drying procedure was carried out using a Christ alpha 14 LSC freeze-dryer (Martin Christ Freeze Dryers). Most likely, malignant cells in the tumors that did not require surgical intervention were highly sensitive to viral infection, while cells in the remaining tumors were more resistant. A debulking surgery has been performed. doi: 10.1158/1535-7163.MCT-10-0479, 84. In this study we did not find much difference in the efficiency and manifestations of the two types of virus preparations. Background: Canine mastocytomas (mast cell tumors) represent a common malignancy among many dog breeds. The outcome of MCT disease depends on many factors. Bresalier RS, Rockwell RW, Dahiya R, Duh QY, Kim YS. Kinoh H, Inoue M, Washizawa K, Yamamoto T, Fujikawa S, Tokusumi Y, et al. Cell surface sialoprotein alterations in metastatic murine colon cancer cell lines selected in an animal model for colon cancer metastasis. doi: 10.1016/j.it.2017.01.008, 11. J Immunol. Figure 3. (2017) 111:2630. Sialic acid polymers are cellular receptors for some paramyxoviruses including Sendai virus (68, 69). Patil SS, Gentschev I, Nolte I, Ogilvie G, Szalay AA. Paramyxoviridae: the viruses and their replication. Charlie's surgery went very well and he's recovering at home (quite stylishly in front of the fireplace). Relevant publications with treatment side effects and efficacy results are listed in Table 1. A high level of sialylation of cell membranes correlates with malignancy. doi: 10.2741/2847, 57. The dark purple cells have a high density of granules, and the purple speckles are free granules that have been released from mast cells. We invite you to read her story. The tumor stage was assigned as distant or stage 4. Since the radical surgical excision of all metastases was not possible the owner requested a debulking surgery, which has been performed. This isimportantbecause treatment recommendations between low-and high-gradetumors are very different., Roughly 80% of mast cells are low-to intermediate-grade andunlikely to reoccurafter surgery. Symptoms vary depending on what organ is affected. Gene Ther. doi: 10.2460/javma.2004.224.79, 38. For high-grademastcelltumorsthe survival timewith surgery aloneis only about 4 months., Ifadditionaltreatment such as radiation therapy or chemotherapy isperformed,theaveragesurvival time increases to 1 year or more. Fujihara A, Kurooka M, Miki T, Kaneda Y. Intratumoral injection of inactivated Sendai virus particles elicits strong antitumor activity by enhancing local CXCL10 expression and systemic NK cell activation. Results of radiation therapy in 19 dogs with cutaneous mast cell tumor and regional lymph node metastasis. Also, certain haplotypes harboring the hyaluronidase genes were identified as disease associated risk factors (22). In addition, sialidase-treated and, consequently, desialylated tumor cells better activate NK cells for IFN-gamma production (76). Another dog was diagnosed with conjunctival melanoma that progressed very rapidly. So, the determination of tumor grade for these cases was based on cytology only and, consequently it was less precise in comparison with other cases. A varietyof treatment protocols are available incorporating multiple drugs as well as corticosteroids.4,5. J Am Vet Med Assoc. (2012) 240:11817. Trends Immunol. J Am Anim Hosp Assoc. Cases 4 and 5 demonstrated that multiple Sendai virus treatments were only able to stabilize the disease before a surgical intervention. Clin Vaccine Immunol. (2004) 41:3717. doi: 10.1016/j.vaccine.2004.01.053, 55. J Immunother. In dogs subjected to surgery alone, margins status and tumor grade predict the disease outcome. 53. Multiple viral injections without surgery caused disease stabilization and long progression free survival of this dog (47). It was also noticed that the tumor penetrated underlying muscle tissue and therefore was staged as regional (stage 2). (2004) 224:7982. Kiupel M, Webster JD, Bailey KL, Best S, Delay J, Detrisac CJ, Fitzgerald SD, et al. doi: 10.1016/j.semcdb.2017.02.002, 10. Mast cells are a type of white blood cell that play an important role in allergic responses. Webster JD, Kiupel M, Yuzbasiyan-Gurkan V. Evaluation of the kinase domain of c-KIT in canine cutaneous mast cell tumors. Rassnick KM, Moore AS, Williams LE, London CA, Kintzer PP, Engler SJ, et al. (1980) 77:43369. MCTs can occur in any dog regardless of breed or sex. Fine-needle aspiration revealed that the tumor was poorly differentiated. Nine months after initial diagnosis, a small trauma at the tumor site caused a painful degranulation event, which was treated with one prednisone injection (2 mg/kg). Despite this low mitotic index, localized stage of MCT and comparatively large clean surgical margins, unexpected tumor relapse (tested by fine-needle aspiration) was noticed 6 weeks after the surgery. Treatment almost always includes surgical removal of the primary tumor when possible. For each treatment up to ten 10100 l aliquots from 1 ml of virus preparation were injected into multiple sites intratumorally, intradermally around the tumor site and under the tumor bed. Even after inactivation with ultraviolet light, Sendai virus particles were able to suppress or eradicate colon (60), bladder (61), and kidney (62) cancers in syngeneic murine models. J Comp Pathol. (2015) 8:4755. (2008) 31:37784. Vet Dermatol. The virus has high affinity for its receptor. The absence of visible side effects in this dog encouraged more frequent (weekly) treatments for later canine patients. doi: 10.1177/1040638711425945, 25. Look for: In most pets, a diagnosis can be made with a needle aspiration of the tumor (a procedure performed with the patient awake using the same size needle used to give a typical vaccine). (1) Inter-digital MCT, 1 week after prednisone injection and before a surgery; (2) MCT site after debulking surgery and 1 month after final virus treatment. Vet Comp Oncol. They develop from particular cells of the immune system called mast cells, which normally treat inflammation and allergic reactions in a dogs body. (2016) 43:10913. Semin Cell Dev Biol. Tumors were graded according to Patnaik et al. Fine needle aspiration or biopsy of any enlarged local lymph nodes. A study of UV-inactivated Sendai virus demonstrated that virus-mediated tumor regression is enhanced by NK cells (62). Palliative therapies such as antihistamines and pain killers can help maintain quality of life but do not slowprogression of the MCT. Sendai virus was prepared as described (64) with some modifications. doi: 10.1007/s00280-007-0553-1, 62. Virchows Arch. (2015) 13:26780. After the tumor is removed, a biopsy is performed on the tumor. Oncolytic potentials of Sendai virus have been studied mainly in Japan. Experienced vets answer all your pet questions via chat or video. The tumor was not cleared but remained the same in size during the virus treatment and 6 months thereafter. Mast cell tumours found in the mouth, on the muzzle, or around the genitals tend to behave more aggressively than mast cell tumours found on other parts of the body. Cancer Res. doi: 10.1073/pnas.77.7.4336, 74. Vet Pathol. (2008) 13:18928. Fine-needle aspiration revealed an intermediately differentiated tumor. Sugiyama M, Kakeji Y, Tsujitani S, Harada Y, Onimaru M, Yoshida K, et al. Malignant cells also could be destroyed through specific anti-tumor immunity triggered by Sendai virus. doi: 10.1593/neo.10732, 82. 52. Case 6. Virotherapy treatment efficacy results are described below. Male golden retriever of 3 years old was presented with cutaneous well differentiated MCT (20 mm in diameter) in the abdominal region. This study was carried out in accordance with the recommendations of Guidelines for Institutional Animal Ethics Committees of the Russian Federation. Recombinant Sendai virus vector induces complete remission of established brain tumors through efficient interleukin-2 gene transfer in vaccinated rats. Neoplasia (2006) 8:10411. MCTs can arise from any skin site on the body and can have a variety of appearances. One of the possible mechanisms of Sendai virus anticancer activity involves a selective direct destruction of cancer cells. The lower titer preparation was used in cases 13, 5, and 6, and the preparation with the higher titer was used in case 4. Outcome and prognostic factors following adjuvant prednisone/vinblastine chemotherapy for high-risk canine mast cell tumour: 61 cases. What is the survival rate for dogs with mast cell tumors? Mol Cancer Res. Von Euler H, Sadeghi A, Carlsson B, Rivera P, Loskog A, Segall T, et al. Two weeks after the debulking surgery two consecutive weekly 1 ml applications of the virus (107 EID50/ml) into the residual part of the tumor were performed. By inducing fusion of infected and uninfected cells the virus efficiently spreads without being exposed to neutralizing antibodies. Washington, DC: National Academy Press (1991). More than 6,000 pet families have chosen PetCure Oncology for their dog or cat's cancer therapy. The multiple lesions might be represented by related or unrelated MCTs (13). Article was somewhat helpful, but could be improved. Front. (1) MCT secondary growth 1 week after the surgical procedure; (2) MCT site, 2 weeks after the first virus treatment; (3) MCT site, 5 weeks after the first virus treatment. Some dogs develop solitary and some multiple lesions. (2009) 46:36264. Figure 1. The tumor was completely cleared after three virus administrations (Figure 3, Case 6). Mast cell-targeted strategies in cancer therapy. This is used to diagnose MCT spread, especially to skin, lymph nodes, and internal organs, Chest Radiographs This imaging will evaluate heart and lungs before anesthesia, and check for concurrent diseases including cancer spread, Tissue Biopsy This biopsy allows microscopic evaluation of the primary MCT, providing confirmation of diagnosis and a tumor grade (low or high), CT Scan This imaging identifies the precise location and size of MCTs for detailed surgery or radiation planning, Maximum damage to the tumor and minimal collateral damage to healthy tissues nearby, Fewer treatment sessions compared to CFRTpatients require only 1-3 sessions, which means fewer anesthetic events, more safety, and less disruption to your schedule, Fast recovery with little to no side effects, Ability to treat tumors previously considered untreatable, PetCure Oncologys radiation oncologists are experienced using SRS/SRT to treat dogs with MCTs. Therefore we can conclude that either of the doses appears to be acceptable for subsequent studies. The chemotherapeutic drug toceranib (Palladia) is an FDA-approved drug for canine mast cell tumor that is showing greatpromise in treatment of this cancer. In model animals even UV-inactivated Sendai virus triggers strong infiltration of a tumor by DCs (60). The purification scheme for Sendai virus used in the study is relatively inexpensive and simple. Vet J. (2016) 15:133345. Appearance of these tumors is highly variable; they might be represented by raised or very deep lesions. In cases 1 and 6 tumor masses were completely cleared without any surgical intervention, after no more than three consecutive virus applications. CFRT can treat the tumor in ways surgery or chemotherapy cant and in many cases is the recommended course of treatment, but there are also disadvantages. They are involved in defense against pathogens and in wound healing. Surgery is the treatment of choice for mast cell tumours, so we were very lucky that Charlie's tumour was on his back and not in a difficult location, such as near an eye or on the muzzle. Secondary growth and lymph nodes were examined using fine-needle aspiration. According to the owner the primary tumor grew fast, from 30 to 120 mm during a 3-week period. (2009) 16:24051. (1998) 329:295302. How serious are mast cell tumors in dogs? doi: 10.1111/vco.12225, 8. MCTs are usually a skin cancer in dogs, but they can spread to lymph nodes, internal organs and bone marrow. Vet Pathol. Allergol Int. It confirmed the initial diagnosis as intermediately differentiated MCT, but revealed extensive necrotic areas in the analyzed sample. All the authors declare no other conflict of interest. Apparently, more clean preparations could be recommended for further studies to avoid potential adverse allergic reactions. The first preparation was done in our research facility and included virus purification as well as concentration through ultra-filtration dialysis of collected allantoic fluid. Primary diagnosis was established by fine-needle aspiration technique, and if a surgery was performed, the diagnosis was a subject of confirmation by histological examination of the excised tumor. 5:116. doi: 10.3389/fvets.2018.00116. To avoid any immunosuppressive effects prednisone was not routinely administered during Sendai virus therapy. On the potential of oncolytic virotherapy for the treatment of canine cancers. The therapy included two or more virus applications administered weekly or biweekly. Mast cells are located in connective tissue and, when activated, rapidly release the contents of their granuleshistamine, proteases, cytokines and heparininto the interstitium contributing to the inflammation response (9). (2016) 14:41746. Moreover, it more accurately predicts MCT's biological behavior. Similar results were obtained using DCs activated by different variants of recombinant Sendai virus strains with transplantable carcinomas including colorectal (83), squamous cell (84), hepatic and prostate cancers (59). According to the dog's owner the tumor grew to the size of 35 mm during 3 weeks period. RECIST evaluation criteria were used for assessing responses of tumors to the viral treatment. Sialylation of 3-methylcholanthrene-induced fibrosarcoma determines antitumor immune responses during immunoediting. Vet Pathol. We give your pet a fighting chance to improve their quality of life. Donnelly L, Mullin C, Balko J, Goldschmidt M, Krick E, Hume C, et al. (2007) 355:12935. However, some breeds including Boxers, Boston Terriers, GoldenRetrievers, and schnauzers are at higher risk. (2014) 74:3199204. copyright 2022 BluePearl. doi: 10.5326/0450014, 37. Induction of efficient antitumor immunity using dendritic cells activated by recombinant Sendai virus and its modulation by exogenous IFN-beta gene. However, we did not yet developed a lyophilization protocol for the purified virus, and storage conditions still requires deep freezing at 80C. The tumor stage was not assigned. Mast cell tumors (MCTs) are common canine malignancies representing up to 20% of canine skin cancers. J Small Anim Pract. Macneill AL. The stabilizing medium consisted of 10 g sucrose (Sigma-Aldrich, S0389) and 5 g lactalbumin hydrolysate (Sigma Aldrich, CAS Number: 91079-44-6) per 100 ml. These factorsdependon the grade of tumor at the time of removal. At PetCure Oncology, our centers offer CFRT as well as the newer and more advanced forms of radiation therapy like SRS/SRT. doi: 10.1016/j.tvjl.2013.02.017, 7. The disease stage was not assigned. When we adopted Bindi in December of 2014 she had a small bump on the bridge of her nose. RIG-I helicase-independent pathway in sendai virus-activated dendritic cells is critical for preventing lung metastasis of AT 6.3 prostate cancer. Mol Ther Oncolytics (2015) 2:15011. doi: 10.1038/mto.2015.11. Antagonism of VEGF by genetically engineered dendritic cells is essential to induce antitumor immunity against malignant ascites. This dog was the first patient to receive the virus treatment at the Veterinary Clinic of the Herzen Oncology Research Institute. Front Biosci. In fact, mast cell tumors are typically diagnosed after a pet owner takes their dog to the veterinarian because theyve felt a lump in or under the skin. doi: 10.1158/1078-0432.CCR-08-1860, 34. A phase II study to evaluate the toxicity and efficacy of alternating CCNU and high-dose vinblastine and prednisone (CVP) for treatment of dogs with high-grade, metastatic or nonresectable mast cell tumours. Hosoya K, Kisseberth WC, Alvarez FJ, Lara-Garcia A, Beamer G, Stromberg PC, et al. In most cases, however,they arefirm, solitary, slow-growing masses of the skin.In some cases, mast cell tumors can also cause severe allergic (anaphylactic) reactions in dogs., Because they are so good at mimicking other skin conditions, its usually impossible to identify a mast cell tumor just by lookingat it, even for your veterinarian.They are more common on middle-aged dogs, and certainbreedslike Boxers and Boston Terriers are more susceptible, so its always a good idea to have your vet look at any unusual skin masses that appear on your dog., Mast cell tumors may not cause any symptoms at all.To help prevent more serious disease, vets recommend checking your dog every few months to look for any masses on the skin.Make an appointment to see your vet if you find:, Aknown mass that has changed in size or color, An unexplained allergic reaction or hive, Somemassesmayappear small and easily movable in (or just under) the skin with little swelling.More aggressive tumorscan appearaslarger, hairlesssores., In some cases, however, a mast cell tumor will result in symptoms, including strong allergic reactionstriggered by the activated immune system. However, it can spread in tumors and kill malignant cells, while sparing the surrounding normal cells. Elston LB, Sueiro FA, Cavalcanti JN, Metze K. The importance of the mitotic index as a prognostic factor for survival of canine cutaneous mast cell tumors: a validation study. all rights reserved. Giles RE, Ruddle FH. Nevertheless, resumed virus therapy completely cleared the recurrent tumor mass with only two weekly administrations of Sendai virus. Case 3. These include:, Retriever breeds(such as Golden Retriever), Your veterinarian will likely recommend creating a skin chart of all known masses and thentakingatissuesample using a fine needle aspiration (FNA)or performinga biopsy on the more concerning masses. c-KIT messenger RNA and protein expression and mutations in canine cutaneous mast cell tumors: correlations with post-surgical prognosis. Mastcelltumorsare the most commonform of skin cancerfoundin dogs.Located in connective tissue throughout the body, mast cells arewhite blood cells that arepart of the immune system.Theyareresponsible forthe allergic response., Mast cellsbecomecancerouswhen they begin dividing abnormallyandgrow intotumors.Mast cellstumorsare easily mistakenfor other skin lesions, like warts or benign lumps. Histological examination was not performed for cases 1 and 6 because the animals didn't undergo surgical treatment. This destruction is most likely promoted by higher affinity of Sendai virus to malignant rather than to normal cells and by the ability of Sendai virus to form syncytia. Usually, these side effects resolved quickly without any intervention. A side effects summary is presented in Table 2. Cancer Chemother Pharmacol. Hematol Oncol Stem Cell Ther. doi: 10.4049/jimmunol.0803845, 83. This information is essential to help the oncologist determine optimal additional treatment options. (2013) 790:95127. The survival rate for high-grade tumors can vary significantly due to the treatment option selected and the individual nature of the tumor.. (2010) 8:13852. Many treatment protocols provide significant life extension for canine patients. Case 5. 75. Steroid anti-inflammatory medications are immuno-suppressive and may mitigate the beneficial virus-induced stimulation of antitumor immunity. When surgically removing any tumours, we have to remove margins of normal looking tissue around the tumour to ensure that there are no tumour cells left behind. Of the six dogs, two did not receive surgery or any other treatment besides the virus injections. Sustained and NK/CD4+ T cell-dependent efficient prevention of lung metastasis induced by dendritic cells harboring recombinant Sendai virus. Res Vet Sci.
