Abstract

Data regarding the outcome of canine rib chondrosarcoma is sparse and varied. While grade of tumour is associated with outcome for canine appendicular chondrosarcoma, the association of grade with outcome for canine rib chondrosarcoma is unclear. This study aimed to correlate the grade of canine rib chondrosarcoma with median survival time. 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). This was not significantly different for patients with grade I versus II versus III (p = 0.82), grade I-II versus III (p = 0.34), or grade I versus II-III (p = 0.49). No variables assessed including age, weight, tumour location (cranial vs. caudal thorax; left vs. right hemithorax), tumour location on rib (proximal, middle, and distal), radiographic appearance (lytic, proliferative, or mixed), elevated serum alkaline phosphatase activity, grade, grade specific histologic features (matrix production, architecture, pleomorphism, cellularity, necrosis, and total score), adjunct therapy post-surgical excision, development of metastatic disease post-surgery, or local recurrence post-surgery were found to impact the risk of death due to chondrosarcoma. In this limited group of patients, the grading scheme reported here, and the other variables assessed did not appear to offer additional prognostic information. However, this data must be interpreted considering the small sample size and thus low statistical power. Additional studies are needed to determine the true impact of grade on outcome for canine rib chondrosarcomas.

组织学分级方案对确诊为肋软骨肉瘤的狗的预后影响
有关犬肋软骨肉瘤预后的数据稀少且各不相同。虽然肿瘤分级与犬附属软骨肉瘤的预后有关,但犬肋软骨肉瘤的分级与预后的关系尚不清楚。本研究旨在将犬肋软骨肉瘤的分级与中位生存时间相关联。研究人员回顾性地确定了原发性肋软骨肉瘤的病例,并根据经调整的人类三级分级方案对肿瘤进行了分级。22名患者被纳入生存分析。中位生存时间为1427天(范围:27-3354天)。Ⅰ级与Ⅱ级与Ⅲ级(P = 0.82)、Ⅰ-Ⅱ级与Ⅲ级(P = 0.34)或Ⅰ级与Ⅱ-Ⅲ级(P = 0.49)患者的生存时间无明显差异。评估的变量包括年龄、体重、肿瘤位置(颅胸与尾部胸腔;左侧胸腔与右侧胸腔)、肿瘤大小、肿瘤大小、肿瘤大小、肿瘤大小、肿瘤大小、肿瘤大小、肿瘤大小、肿瘤大小、肿瘤大小、肿瘤大小等。右半胸)、肿瘤在肋骨上的位置(近端、中间和远端)、放射学表现(溶解性、增殖性或混合性)、血清碱性磷酸酶活性升高、分级、分级特定组织学特征(基质生成、结构、多形性、细胞)、结构、多形性、细胞性、坏死和总分)、手术切除后的辅助治疗、手术后转移性疾病的发生或手术后局部复发都会影响软骨肉瘤导致死亡的风险。在这一有限的患者群体中,本文报告的分级方案和其他评估变量似乎并未提供额外的预后信息。不过,在解释这些数据时必须考虑到样本量较小,因此统计能力较低。要确定分级对犬肋软骨肉瘤预后的真正影响,还需要进行更多的研究。

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.
