Objective To improve the diagnosis and treatment of chromophobe renal cell carcinoma and its understanding of this type of renal cell carcinoma. Methods The clinical data of 15 cases of chromophobe renal cell carcinoma were retrospectively analyzed. 10 males and 5 females. Age 47 ~ 74 years old, with an average of 57 years old. All underwent radical nephrectomy. Results Postoperative pathology confirmed renal cell carcinoma. Pathological stage: pT1N0 M0 6 cases, pT2 N0 M0 5 cases, pT3bN0 M0 2 cases, pT1N2 M0 1 case, pT2 N2 M0 1 case. Pathological grade: G2 10 cases, G3 5 cases. Eleven patients were followed up for 2 to 31 months with an average of 19 months. One died of heart disease, one had local recurrence and 9 had no tumor. Conclusion Kidney chromophobe carcinoma is a rare form of renal cell carcinoma with a special morphology. Radical nephrectomy is the preferred method of treatment of chromophobe renal cell carcinoma. Compared with the same period, other types of kidney cancer at the same level, the prognosis of renal chromophobe cancer is better.
