摘　　要：目的 探讨对比分析肺肉瘤样癌与肺鳞癌的临床及CT影像特点。方法 选取本院24例肺肉瘤样癌与26例肺鳞癌患者临床及影像资料行回顾性分析,两组间采用t检验、卡方检验或Fisher精确检验分析。结果 肺肉瘤样癌组男性比例(62. 5%)低于肺鳞癌组(92. 3%),周围型比例(83. 3%)高于鳞癌组(57. 7%),邻近组织侵犯及远处转移出现情况高于鳞癌组,强化值(19. 4±11. 7) HU明显低于鳞癌组(31. 4±15. 6) HU,差异有统计学意义(P <0. 05),而两组在年龄、吸烟史、临床症状及其他影像学表现方面差异无统计学意义(P> 0. 05)。结论 肺肉瘤样癌与肺鳞癌的临床特点及一般CT表现虽然具有重叠性,但在发病年龄、部位、邻近组织侵犯、远处转移及强化程度方面有差异,有助于两者之间的鉴别诊断。Objective The aim of this study was to analyze the clinical and imaging features of pulmonary sarcomatoid carcinoma and squamous cell lung cance.Methods The imaging data and clinical data of 24 patients with pulmonary sarcomatoid carcinoma and 26 patients with squamous cell lung cancer in our hospital were retrospectively evaluated,and analyzed using independent-samples T test,chi-squre test orFisher exact test.Results The proportion of male in patients with pulmonary sarcomatoid carcinoma(63%)was lower than that with squamous cell lung cancer(92%),the proportion of peripheral type(83%)was higher than that in squamous cell lung cancer(58%),the incidence of adjacent tissue invasion and distant metastasis was higher than that in squamous cell carcinoma group,the enhancement value was(31.00±7.66)HU,significantly lower than that in squamous cell lung cancer(54.11±7.81)HU.There was significant difference between the two groups(P<0.05),while there was no significant difference between the two groups in age,gender,smoke,clinical symptoms and other imaging performances(P>0.05).Conclusion Although the clinical features and general CT findings of pulmonary sarcomatoid carcinoma are overlapped with squamous cell lung cancer,there are differences in age,location,invasion of adjacent tissues,distant metastasis and enhancement,which is helpful for the differential diagnosis between them.
