BACKGROUND
To study the biological behavior of renal squamous cell carcinoma (RSCC).
METHODS
Fifteen cases of RSCC were retrospectively studied. These cases were classified as central (eight cases) and peripheral (seven cases) types by the tumor location. The clinical data and computed tomographic findings were analyzed and compared.
RESULTS
High incidence (87%) of urolithiasis was observed. The prognosis of RSCC was very poor, with a median survival time of 3.5 months. The infectious symptoms, central location, and modified stage IV of the tumor were the poor prognostic factors of RSCC. Two types of RSCC were different in the presenting symptoms, lymph node metastasis, modified tumor staging, and survival time.
CONCLUSION
The central and peripheral types of RSCC were different biologically. High index of suspicion should be maintained when identifying the subtle clues of malignancy in patients with urolithiasis.
背景
研究肾鳞状细胞癌（RSCC）的生物学行为。
方法
回顾性研究15例RSCC病例。根据肿瘤位置将这些病例分为中央型（8例）和外周型（7例）。分析并比较临床资料和计算机断层扫描结果。
结果
观察到尿石症的高发病率（87%）。RSCC的预后非常差，中位生存时间为3.5个月。感染症状、肿瘤的中央位置和改良IV期是RSCC的不良预后因素。两种类型的RSCC在症状表现、淋巴结转移、改良肿瘤分期和生存时间方面存在差异。
结论
RSCC的中央型和外周型在生物学上存在差异。在识别尿石症患者恶性肿瘤的细微线索时应保持高度怀疑。
