The aim of this study is to assess the concordance between histopathologic findings of LNs and cytology and flow cytometry (FC), respectively, and to evaluate the ability of FC to differentiate between metastatic (HN2-HN3) and non-metastatic (HN0-HN1) LNs. Overall, 117 LNs from 64 dogs with first occurring MCTs were submitted for cytology, histology and FC. LNs were cytologically and histologically classified according to Krick and Weishaar systems, respectively. Using FC, mast cells (MCs) were identified as IgE+ CD117+ CD5- CD21- cells and quantified as a percentage. When compared with histologic classification, cytology showed an accuracy of 88.2% in distinguishing between metastatic and non-metastatic LNs but did not detect 25.3% of metastatic cases. FC revealed an increase in the median percentages of MCs across histologic classes, progressing from HN0 to HN3. ROC curves pinpointed 0.3% as the optimal cut-off for distinguishing between metastatic and non-metastatic LNs, with an accuracy of 84.3%. A 1.1% cut-off proved valuable in identifying HN3 LNs. The combined interpretation of cytology and FC increased accuracy to 92.2%. An algorithm for guiding the combined interpretation of cytology and FC is suggested based on these findings. In conclusion, FC proves beneficial in enhancing the early detection of metastatic LNs, particularly when utilised alongside cytology. Histopathology remains essential for confirmation, enabling the discrimination of HN classes or, in doubtful cases, for the detection or exclusion of nodal metastases.","PeriodicalId":23693,"journal":{"name":"Veterinary and comparative oncology","volume":" ","pages":"1-9"},"PeriodicalIF":2.3,"publicationDate":"2025-03-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142476054","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"农林科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

In humans, LA characterised as tertiary lymphoid structures (TLSs) improve the prognosis of many tumours, including sarcomas. We sought to determine if LA meeting a size criterion (> 700 cells) in canine sarcomas met the criteria of TLS and the overall prevalence of LA of any size. RNA expression in large LAs versus aggregate-adjacent sarcoma tissue (AAS) was measured in laser capture microdissected tissue and compared to curl-derived RNA from aggregate-free sarcomas and lymph nodes. CD3, CD20, MUM-1 and PNAd expressions were measured using immunohistochemistry. CD20 and CD3 mRNA were more highly expressed in LA versus AAS (13.8 fold, p = 0.0003 and 2.3 fold, p = 0.043). This was supported by the IHC findings. The large LAs were also enriched in chemokine RNA expression characteristic of TLS (CXCR5 5.8 fold, p < 00001, CCL19 3.68 fold, p = 0.0209, CCL21 6.87 fold, p = 0.0209 and CXCL13 2.68 fold, p = 0.0924).

Retrospectively, cases of primary rib chondrosarcoma were identified, and tumours were graded based on a 3-tier adapted human grading scheme. Twenty-two patients were included in the survival analysis. The median survival time was 1427 days (range: 27-3354 days).

In this limited group of patients, the grading scheme reported here, and the other variables assessed did not appear to offer additional prognostic information.

Pathologic fracture following stereotactic body radiation therapy for canine appendicular osteosarcoma (OSA) frequently results in limb amputation or euthanasia. Additional tools are needed to better predict the risk of fracture development. Our objectives were to determine if any relationships could be identified between BCM and the occurrence of a pathologic fracture and/or survival time in dogs with naturally occurring OSA. Forty-seven dogs with a confirmed OSA and whole-body CT pre-SBRT were included. Several BCM were evaluated, including abdominal volume, visceral adipose tissue volume, whole-body volume, whole-body adipose tissue volume, normalised cross-sectional area of the epaxial muscles at the mid-body of the 13th thoracic vertebra, and attenuations of adipose tissue and epaxial muscles. No BCMs were correlated with survival time. The volume of the entire body (cm3) was significantly positively associated with development of a fracture. No other BCM were correlated with the development of a fracture. The volume of the abdomen (cm3) among our patient subset was positively correlated with the volume of the entire body, and the volume of visceral adipose tissue (cm3) was positively correlated with the total body volume of adipose tissue (cm3).

Nowadays, immunotherapy targeting immune checkpoints has been described as a complementary treatment for several human cancers, but it is still very scarcely studied in veterinary medicine. Therefore, this study aimed to investigate the expression of the checkpoint proteins programmed death-ligand 1 (PD-L1) and cytotoxic T-lymphocyte antigen-4 (CTLA-4) to evaluate their potential as therapeutic targets for MCT. Through immunohistochemical study, it was analysed the expression of PD-L1 and CTLA-4 in 74 MCT cases from the archive of the Veterinary Pathology Laboratory of the University of Porto (LabPatVet). Tumour size, histological grade, ki-67 proliferation index, mitotic count and presence of metastatic disease were also assessed. Most of the cases expressed both immune checkpoints in neoplastic cells. There was a statistically significant inverse association between the expression of CTLA-4 and MCT grade (p < 0,001) and mitotic count (p < 0.001). PD-L1 was significantly and negatively related to HG (p = 0.004), and tumour size (р = 0.014). Tumour size, histological grade and mitotic count were positively associated with metastatic disease. Additionally, it was observed that the expression of PD-L1 and CTLA-4 was interrelated (p < 0.001).

To assess stromal reprogramming, we analysed CAS from 21 CMM, 14 CCM and normal stroma from 10 skin and 9 oral mucosa samples by laser-capture microdissection followed by RNA sequencing. Results were assessed in relation to subtypes, prognostic factors including mitotic count (MC), ulceration, necrosis, pigmentation and immune cell infiltration (CD3, CD20 and CD68), scored using immunohistochemistry and RNA in situ hybridisation. Stromal reprogramming was evident in both subtypes but significantly more pronounced in CMM. Immune-excluded tumours exhibited higher MC than desert/cold ones. MC strongly correlated with genes associated with B-cells, T-helper cells and CTLA4 in CCM, suggesting CAS reprogramming to depend on tumour malignancy. Finally, we identify an immune-suppressive stromal signature in a subset of CMM characterised by the downregulation of key immune checkpoints and pathways.

Tumour-derived extracellular vesicles and soluble factors remodel the microenvironment of distant metastatic organs before subsequent metastasis.

We necropsied and sampled lung tissues from dogs with naturally occurring treatment-naïve OS (n = 15) and control dogs without cancer (n = 10). We further divided dogs with OS into those having lung metastases (n = 5) and those without (n = 10). We stained formalin-fixed paraffin-embedded tissues using multiplex immunofluorescence to quantify the number of bone marrow-derived cells, monocytes and macrophages in the lung samples from each dog. The numbers of CD204+ macrophages, CD206+ macrophages and monocytes and CD11d+ bone marrow-derived cells (BMDCs) were significantly higher in the pre-metastatic lung of dogs with OS (n = 10) than in control dogs without cancer (n = 10). Furthermore, the total nucleated cell (DAPI+) density was higher before metastasis than in healthy lungs. In dogs with established metastases, the number of CD11d+ BMDCs was significantly lower than in the pre-metastatic lung, suggesting this recruitment is transient. Our study provides evidence of PMN existence in a naturally occurring cancer model similar to those observed in pre-clinical murine models. BMDCs are recruited to the lungs before metastases have developed.
