目的探讨乳头状肾细胞癌的治疗方法和临床特点。方法回顾分析我院十六年来收治的10例乳头状肾细胞癌患者的住院资料和诊断治疗过程记录。其中可观察到有7例男性患者,3例女性患者。最小年龄28岁,最大年龄77岁,平均年龄48岁。左侧肾患肿瘤病者6例,右侧肾患肿瘤病者4例。结果发生早期局限性癌的8例患者中5年生存率为100%,但是有1例在随访第10年出现转移现象,在对其进行转移瘤的切除术后已生存至今。其他2例中出现肺转移瘤2例,进行肺转移瘤的切除和生物化疗后分别生存3～4年。结论乳头状肾细胞癌作为一种特殊类型的肿瘤,其在我国发病率较低。对于局限性的乳头状肾细胞癌术后生存率高;对于转移的乳头状细胞癌在进行手术切除转移部位的癌对提高后期生存期有很大的帮助。
Objective To investigate the treatment and clinical features of papillary renal cell carcinoma. Methods A retrospective analysis of our hospital for 16 years admitted 10 cases of papillary renal cell carcinoma in hospital information and diagnosis of treatment records. Of these, seven were observed in males and three were females. The youngest age of 28 years, the maximum age of 77 years, mean age 48 years. Left kidney cancer patients in 6 cases, right kidney cancer patients in 4 cases. Results The 5-year survival rate was 100% in 8 patients with localized early cancers, but 1 patient developed metastases at the 10th year of follow-up and survived after resection of the metastases. In the other two cases, 2 cases of lung metastases occurred, and 3 to 4 years after resection of lung metastases and biochemotherapy respectively. Conclusion Papillary renal cell carcinoma as a special type of tumor, its incidence in our country is low. For the limitations of papillary renal cell carcinoma postoperative survival rate is high; for the transfer of papillary carcinoma in the surgical removal of cancer metastasis site to improve the late survival of a great help.
