Withrow & MacEwens small animal clinical oncology. This raised the question as to whether prior studies that included dogs with T-cell lymphoma may underestimate survival times for dogs with B-cell lymphoma treated with single-agent DOX. Laverdia Ca-1 (verdinexor) was originally developed by a company working on human cancer treatments. Therefore, when appropriate, we recommend combining this drug with another chemotherapy drug (typically doxorubicin).

An inherent limitation by the retrospective nature of this study is the lack of standardization of response assessment. There are many options for rescue protocols. Combined with Laverdia: $250-$450. Fasting reduces the incidence of vincristine-associated adverse events in dogs. Additional prospective investigation will be required to explore the implication that VCR dose intensity and/or shorter overall temporal drug exposure in this protocol may result in diminished efficacy. While the distinction of high- and low-grade lymphoma is ideally made based on histopathological evaluation, cytologic assessment of cell size is commonly used in practice to make this determination and has been reported to have a good correlation with histologic samples [29]. Dogs with multicentric T-cell lymphoma are commonly treated with CHOP chemotherapy protocols that include cyclophosphamide, doxorubicin, vincristine and prednisone. Dogs with a confirmed diagnosis of multicentric lymphoma whose owners present to the UWVC oncology service for consultation and elect to treat their dog with 19-week CHOP protocol will be given the option to participate in the clinical trial. We feel this is unlikely, however, as the majority (79%) dogs had treatment initiated at a standard DOX dose of 30mg/m2 (or 1mg/kg if less than 15kg) and the median dose was only 10% reduced for those dogs that received a reduced DOX dose at treatment initiation.

The 12-week protocol was designed to be 58% more dose intense than the 19-week protocol for both doxorubicin and cyclophosphamide; however, it was 21% less dose intense for vincristine (VCR). Vet Comp Oncol. 2015;13(4):34862. Mixed breed dogs (27%) and golden retrievers (12%) were the most common breeds in this study. We hypothesized that these dogs would have an improved overall response rate, progression-free survival (PFS), and overall survival (OS) as compared to previous studies that included dogs with B- and T-cell lymphoma. All dogs received a 19-week L-CHOP chemotherapy protocol with randomisation (1:1) into placebo or AT-005 groups. The median starting dose for these dogs was 27mg/m2 (range, 2527mg/m2). This newness is useful to rescue protocols because the cancer cells have usually developed resistance to the old drugs, rendering them practically useless.

Rebhun RB, Kent MS, Borrofka SA, Frazier S, Skorupski K, Rodriguez CO. CHOP chemotherapy for the treatment of canine multicentric T-cell lymphoma. Our hypothesis was not supported by our results as this DOX and prednisone protocol, with or without L-ASP induction, resulted in an ORR of 84%, PFS of 147days, and OS of 182days. When our AI system processes through up to 300 different chemotherapy medicine combinations, we develop a chart that predicts how the treatment will impact your dog, as well as their predicted time frame of relapse.

However, response rates to a single dose of DOX for dogs with T-cell lymphoma is 50% compared to a 100% response rate for dogs B-cell lymphoma, suggesting that DOX may be a less efficacious drug for the treatment of T-cell lymphoma in dogs [12]. It is possible that based on the guidelines, some of the partial responders may have been categorized as having stable disease which could have led to an overestimation of the ORR in this study. He was the only dog treated by the clinic that remained in remission during this period of time. doi: 10.1371/journal.pone.0274261. has an ORR of 100%, but a relatively short PFI and OS of 252 and 341days, respectively [10].

One dog died the day following DOX administration and a second dog died of sepsis secondary to neutropenia 9days after DOX administration and therefore response could not be assessed but was documented to be in a complete response (CR) at the time of death. This is one of the most effective treatments for T-cell lymphomas, a cancer that otherwise would be difficult to treat. Evaluation of a high-dose chemotherapy protocol with no maintenance therapy for dogs with lymphoma. Estimated cost per treatment: $500 (combination treatment will increase cost).

Follow-up information was obtained from medical records and by phone calls to the referring veterinary hospitals. Therefore, a subset of B-cell lymphomas with poor prognostic factors may have been within this study population, and potentially influencing the PFS and OS negatively. Despite the difference in the timing of DOX administration, our continuous protocol had a comparable median number of treatments to the intermittent treatment protocol (5 treatments vs. 4.5 treatments), as well as similar outcomes (ORR of 78% and median survival time of 169.5days) [26].
