Abstract

IntroductionSarcomatoid renal cell carcinoma (sRCC) is rare but highly aggressive and is associated with poor prognosis and limited treatment responsiveness. Despite several studies investigating its clinicopathological features, existing research is often limited by small sample sizes and short follow-up periods, and currently, no prognostic risk model is specific to patients with non-metastatic sRCC. This study aimed to investigate the clinicopathological characteristics of patients with non-metastatic sRCC and develop a predictive model for postoperative mortality risk.MethodsIn this retrospective study, we analyzed the clinical data of 45 patients diagnosed with non-metastatic sRCC who underwent surgical treatment at our institution's Department of Urology, between January 2008 and June 2024. These patients were compared with 527 patients with non-sarcomatoid renal cell carcinoma (non-sRCC). The primary endpoint was death, and the exact cause of death was recorded. Routine postoperative examinations and treatment details were documented through outpatient and inpatient electronic medical record systems.ResultsThe results indicated significant differences in body mass index, hypertension, surgical approach, nephrectomy type, surgical duration, maximum tumor diameter, tumor necrosis, T stage, and Ki-67 expression between patients with sRCC and those with non-sRCC (P < 0.05). Survival analysis revealed that the cancer-specific survival (CSS) for patients with sRCC was significantly lower than that for patients with non-sRCC (P < 0.001). Cox univariate and multivariate analyses identified maximum pathological tumor diameter, T stage, and high Ki-67 expression as independent risk factors. Based on these factors, we developed a postoperative mortality risk prediction model for patients with sRCC, with the calibration curves demonstrating a good fit of the model.ConclusionsThe proposed model is designed for patients with non-metastatic sRCC. It has potential clinical application value, aiding in the identification of high-risk patients and providing guidance for individualized treatment and close follow-up.

非转移性肉瘤样肾细胞癌患者的临床病理特征及术后死亡风险预测。
肉瘤样肾细胞癌(sarcomatoid renal cell carcinoma, sRCC)是一种罕见但具有高度侵袭性的疾病,其预后较差,治疗反应性有限。尽管有一些研究调查了其临床病理特征,但现有的研究往往受到样本量小和随访时间短的限制,目前还没有针对非转移性sRCC患者的预后风险模型。本研究旨在探讨非转移性sRCC患者的临床病理特征,并建立术后死亡风险的预测模型。方法在这项回顾性研究中,我们分析了2008年1月至2024年6月在我院泌尿外科接受手术治疗的45例非转移性小细胞癌患者的临床资料。这些患者与527例非肉瘤样肾细胞癌(non-sRCC)患者进行比较。主要终点为死亡,并记录了确切的死亡原因。常规术后检查和治疗细节通过门诊和住院电子病历系统记录。结果sRCC患者与非sRCC患者在体重指数、高血压、手术入路、切除类型、手术时间、最大肿瘤直径、肿瘤坏死、T分期、Ki-67表达等方面均存在显著差异(P < 0.05)
