摘要

犬皮肤肥大细胞瘤(MCT)目前根据世界卫生组织(WHO)的分类法进行分期,该分类法自最初制定以来一直未变。我们的研究旨在评估新型 pTNM 分期系统的可靠性,该系统包含肿瘤范围(T)、淋巴结受累(N)、远处转移(M)和两级组织学分级。我们分析了患有一种或多种切面/皮下完全分期 MCT 的犬只的医疗记录,这些犬只均接受了肿瘤切除术和淋巴结切除术,除非出现远处转移,在这种情况下才进行药物治疗。狗被分为三个阶段:I期(T1-2N0M0)、II期(T1-2N1M0)和III期(远处转移)。I 期和 II 期又根据组织学分级分为 "低 "和 "高"。b期以下的定义是肿瘤直径≥3厘米和/或出现溃疡。在 226 只狗中,87 只(38.5%)处于 I 期(I-低,n = 75;I-高,n = 12),107 只(47.3%)处于 II 期(II-低,n = 59;II-高,n = 48),32 只(14.2%)处于 III 期。新提出的分期系统能够显著地对人群的进展时间和肿瘤特异性生存率进行分层。与I期-低相比,I期-高(18.3倍)、II期-低(8.5倍)、II期-高(41.5倍)和III期(110.3倍)的进展风险明显增加。该分期系统对皮肤和皮下 MCT 的预后都有很高的预测价值。前瞻性验证研究对比较这一新系统与目前的世界卫生组织分期系统并进一步验证其准确性和临床实用性至关重要。

Incorporation of Biologic Variables Into the Staging for Canine Cutaneous and Subcutaneous Mast Cell Tumours: Proposal of the UBo pTNM System.

Canine cutaneous mast cell tumours (MCTs) are currently staged based on the World Health Organization (WHO) classification, which has remained unchanged since its initial formulation. Our study aimed to assess the reliability of a novel pTNM staging system, which incorporates tumour extent (T), lymph node involvement (N), presence of distant metastases (M) and the two-tier histologic grade. We analysed medical records of dogs with one or more cutaneous/subcutaneous completely staged MCT, undergoing tumour excision with lymphadenectomy, unless distant metastases were present, in which cases, medical therapy was administered. Dogs were categorized into three stages: I (T1-2N0M0), II (T1-2N1M0) and III (distant metastases). Stages I and II were further divided based on histologic grade into 'low' and 'high'. Substage b was defined as the presence of tumour diameter of ≥3 cm and/or ulceration. Of 226 dogs, 87 (38.5%) were in Stage I (I-low, n = 75; I-high, n = 12), 107 (47.3%) in Stage II (II-low, n = 59; II-high, n = 48), and 32 (14.2%) in Stage III. The newly proposed staging system was able to significantly stratify the population for both time to progression and tumour-specific survival. Compared to Stage I-low, the risk of progression increased significantly for Stage I-high (18.3 times), Stage II-low (8.5 times), Stage II-high (41.5 times) and Stage III (110.3 times). The staging system was highly prognostic for both cutaneous and subcutaneous MCTs. Prospective validation studies are essential to compare this new system with the current WHO staging and further validate its accuracy and clinical utility.

期刊介绍: Veterinary and Comparative Oncology (VCO) is an international, peer-reviewed journal integrating clinical and scientific information from a variety of related disciplines and from worldwide sources for all veterinary oncologists and cancer researchers concerned with aetiology, diagnosis and clinical course of cancer in domestic animals and its prevention. With the ultimate aim of diminishing suffering from cancer, the journal supports the transfer of knowledge in all aspects of veterinary oncology, from the application of new laboratory technology to cancer prevention, early detection, diagnosis and therapy. In addition to original articles, the journal publishes solicited editorials, review articles, commentary, correspondence and abstracts from the published literature. Accordingly, studies describing laboratory work performed exclusively in purpose-bred domestic animals (e.g. dogs, cats, horses) will not be considered.
