Values Of Multi Slice Spiral In Diagnosis And Differential Diagnosis Of Renal Cell Carcinoma

Renal cell carcinoma(RCC) is the most common malignant tumor of the kidney, accounting about 85%- 90% of renal tumor, which accounting for more than 2% of the global cancer patients[1]. Recently, the incidence of kidney cancer is increased.There are a variety of pathological subtypes, clear cell carcinoma, papillary carcinoma, and anaerobic color cells. Among them, clear cell carcinoma is the most common one. Different subtypes of renal cancer have different prognosis, outward invasion and metastatic probability because of the different nucleus levels,with the clear cell carcinoma the most invasived, and the papillary carcinoma cell carcinoma the second and anaerobic color cells. Preoperatively making the use of imaging methods to accurate identification of different subtypes of renal cancer will do a great favor for the clinicians to choose the best means of treatments for patients. Multislice CT(MSCT) for its scanning speed, the advantages of high density, plays a very important role in the preoperative diagnosis and differential diagnosis of renal cancer.In this article,the clinial and radiology datas of 61 cases of renal carcinoma were analysised and compared in order to find whether there was vale of the MSCT dual phase scanning in the diagnosis and differential diagnosis of the kidney cancer subtype common.Objective: To investigate the value of MSCT dual phase enhanced scanning in the diagnosis and differential diagnosis of renal cell carcinoma.Materials and methods: 61 cases confirmed by surgery and pathology of renal cancer patients were collected. And MSCT data of cortex and substance stages in 48 clear cell carcinoma cases, 8 papillary carcinoma cases, suspicion color cell carcinoma 5 cases were also collected and compared. The patient’s age, tumor size, areas of the cases, each period to strengthen the amplitude and the dynamic enhanced CT value ways, hemorrhage or not, necrosis in capsule, calcification were statistically analysised and comparisoned.Results: There was no statistical difference in the CT values of clear cell carcinoma, papillary carcinoma and suspicion between color cell carcinoma(P>0.05).When compared with the anaerobic color cells, there was significantly in the CT values of the clear cell carcinoma and papillary carcinoma of the stage of cortex or the essence, the strengthening amplitudes and the strengthening methods. There was significant difference between the clear cell carcinoma and papillary carcinoma in bleeding(P<0.05) and necrosis or not among the three renal carcinoma(P<0.05), but with no significant difference in tumor position, size, patients’ age(P>0.05)Conclusion: One of the most important parameters to distinguish the subtypes of renal cancer maybe the amplitude strengthen CT values of the tumor. And the reinforcement ways, capsule of necrosis and hemorrhage or not of the kidney cancer subtypes may do some asistantance in diagnosis and differential diagnosis.
