Abstract
Canine lymphoma, the most prevalent haematopoietic tumour in dogs, presents significant challenges in veterinary oncology. This study investigates the prognostic value of the neutrophil-to-lymphocyte ratio (NLR) in small-sized dogs (≤10 kg) with multicentric lymphoma. In this retrospective study, we examined medical records and haematological data from 35 dogs to assess the association between NLR and two key outcomes: time-to-progression (TTP) and lymphoma-specific survival (LSS) using Cox proportional hazards models. Our findings revealed a significant correlation between elevated NLR and a worse prognosis, as evidenced by TTP (p = 0.005) and LSS (p = 0.001). NLR is linked to increased hazard ratios (HRs) for the time-to-progression rate (TTPR) at 180, 360 and 540 days (p = 0.001, p = 0.003 and p = 0.005, respectively) and the lymphoma-specific survival rate (LSSR) at the same intervals (p = 0.016, p = 0.001 and p = 0.001, respectively). Cutoff value of 3.764 for NLR was established, above which there is a significantly increased risk of early disease progression and decreased survival. Additionally, our analysis indicates that dogs with substage b exhibited earlier progression than those with substage a, evident in overall (p = 0.026) and TTPR at 180 days (p = 0.004), 360 days (p = 0.018), 540 days (p = 0.026) and LSSR at 180 days (p = 0.033). The results underscore the potential of NLR as a prognostic marker in cases of dogs ≤10 kg with multicentric lymphoma, suggesting that higher NLR is associated with a poorer prognosis.

Polymers (Basel) 2024; 16:2132. [PMID: 39125158 PMCID: PMC11314107 DOI: 10.3390/polym16152132] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/03/2024] [Revised: 07/23/2024] [Accepted: 07/24/2024] [Indexed: 08/12/2024] Open
Abstract
L-asparaginases (ASP) and Doxorubicin (Dox) are both used in the treatment of leukemia, including in combination. We have attempted to investigate if their combination within the same targeted delivery vehicle can make such therapy more efficacious. We assembled a micellar system, where the inner hydrophobic core was loaded with Dox, while ASP would absorb at the surface due to electrostatic interactions. To make such absorption stronger, we conjugated the ASP with oligoamines, such as spermine, and the lipid components of the micelle-lipoic and oleic acids-with heparin. When loaded with Dox alone, the system yielded about a 10-fold improvement in cytotoxicity, as compared to free Dox. ASP alone showed about a 2.5-fold increase in cytotoxicity, so, assuming additivity of the effect, one could expect a 25-fold improvement when the two agents are applied in combination. But in reality, a combination of ASP + Dox loaded into the delivery system produced a synergy, with a whopping 50× improvement vs. free individual component. Pharmacokinetic studies have shown prolonged circulation of micellar formulations in the bloodstream as well as an increase in the effective concentration of Dox in micellar form and a reduction in Dox accumulation to the liver and heart (which reduces hepatotoxicity and cardiotoxicity). For the same reason, Dox's liposomal formulation has been in use in the treatment of multiple types of cancer, almost replacing the free drug. We believe that an opportunity to deliver a combination of two types of drugs to the same target cell may represent a further step towards improvement in the risk-benefit ratio in cancer treatment.

Hematological and blood biochemistry parameters as prognostic indicators of survival in canine multicentric lymphoma treated with COP and L-COP protocols. Vet World 2024; 17:344-355. [PMID: 38595652 PMCID: PMC11000476 DOI: 10.14202/vetworld.2024.344-355] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/09/2023] [Accepted: 01/18/2024] [Indexed: 04/11/2024] Open
Abstract
Background and Aim Hematological and blood chemistry parameters are crucial for evaluating and monitoring canine multicentric lymphoma during chemotherapy. Pre-treatment hematological and blood chemistry parameters can be used as prognostic survival outcomes for this disease. Therefore, this study aimed to investigate the effect of hematological and blood chemistry parameters pre-treatment and 4 weeks post-treatment on the survival outcomes of dogs treated with either a combination of cyclophosphamide, vincristine, and prednisolone (COP) or a combination of COP with L-asparaginase (L-COP) protocols. Materials and Methods We conducted a retrospective study. Medical records and hematological and blood chemistry parameters of 41 dogs with multicentric lymphoma treated with L-COP (n = 26) and the COP protocols (n = 15) were obtained from the hospital information system. Most cases were classified as high-grade lymphoma based on the Kiel cytological classification. The effects of hematological and blood chemistry parameters on survival outcomes were investigated using the Cox proportional hazard regression model. The median survival time (MST) for each hematological and blood chemistry parameter affecting survival outcome was established and compared using the Kaplan-Meier product limit method with the log-rank test. Results Dogs with high-grade multicentric lymphoma that were treated with the COP protocol and had monocytosis at pre-treatment had a significantly shorter MST than dogs with normal monocyte counts (p = 0.033). In addition, dogs with azotemia, both pre-treatment and 4 weeks post-treatment, had a significantly shorter MST than dogs with normal serum creatinine levels (p = 0.012). Dogs with high-grade multicentric lymphoma treated with the L-COP protocol who had hypoalbuminemia (serum albumin concentration <2.5 mg/dL) at both pre-treatment and 4 weeks post-treatment had a significantly shorter MST than dogs with normal serum albumin levels (p < 0.001). Furthermore, dogs with leukocytosis at 4 weeks post-treatment had a significantly shorter MST than those with a normal total white blood cell count (p = 0.024). Conclusion Serum albumin level can serve as a simple negative prognostic indicator of survival outcomes in dogs with high-grade multicentric lymphoma treated with the L-COP protocol. Dogs with hypoalbuminemia pre-treatment and 4 weeks post-treatment tended to have a shorter MST than those with normal serum albumin concentrations.

Abstract
While canine lymphoma is a relatively common and important disease seen by veterinarians, there are limited comprehensive reviews of the literature regarding the remission and survival times following chemotherapy, and the associated prognostic factors. This comprehensive thematic review covers the available veterinary literature covering treatment outcomes and identified prognostic factors. A lack of standardised approaches to evaluate and report the outcomes was identified, including factors that would alter the duration of responses by weeks, or occasionally months. After publication of the suggested reporting criteria, this has improved but is still not uniformly applied. The prognostic factors included for evaluation varied from as few as three to seventeen, with over 50 studies using only univariate analysis. Individual papers reported much longer outcomes than others, but assessing the outcomes overall, there has been minimal change over the last 40 years. This supports the belief that novel approaches for lymphoma therapy will be required to substantively improve outcomes.

Abstract
L-asparaginase is used in chemotherapy for acute lymphoblastic leukemia and other
cancers. L-asparaginase derived from bacterial source triggers immune responses.
The current study investigates Solanum nigrum as a novel and
latent source of L-asparaginase to minimize immunological reactions. The
antitumor activity of SN methanol extract was determined using the potato disc
assay. InterPro Chimera and InterPro were used to predict the amino acid
sequence of L-asparaginase and its anticancer activity. Purification of the
enzyme was carried out to homogeneity of 1.51-fold with a recovery of 61.99%. At
optimal conditions of 36.5°C, pH 8.6, and 8.5 g/mL substrate, fruit (crude
extract) revealed an L-asparaginase titer of 48.23 U/mL. The molecular weight of
the enzyme was calculated to be 32 ± 5 kDa using SDS PAGE. The fruit’s total
flavonoids and phenolic contents are 0.42 ± .030 g/mL and 94 ± 1.9 mg CAE,
respectively. Anti-tumorigenic efficacy was determined to be 66% against
Agrobacterium tumefaciens. Additionally, the extract
possesses potent antifungal and antibacterial properties. Molecular docking
provided the structural motifs and underlying interactions between
L-asparaginase, N-acetylglucosamine, murine, and chitin. SN contains high levels
of the enzyme L-asparaginase and phytochemicals, making it a potential source of
anticancer drugs.
