Abstract:
Objective To investigate the clinic pathologic features of young patients with renal malignant tumour by comparing with older patients. Methods The clinical data of 83 younger adults(age,≤40 years) with renal cell carcinoma and 703 cases of older renal cell carcinoma (age＞40 years)was analyzed and compared retrospectively. All of the patients were surgically treated between 1986and 2007. Results Among patients with symptoms, younger female patients were more likely to have abdominal pain(12/27, 44.4% vs. 154/703, 21.9%)and mass (2/27, 7.4% vs. 154/703,1.3%)than older (P＜0.05). The older groups were more likely to have dear cell carcinoma than in the younger(501/703, 71.3% vs. 47/83, 56.6%)(P＜0.05). The rate of PRCC has the trends to be higher in young patients than that in older patients (21/83, 25.3% vs. 118/703, 16.8%) (P=0.054),especially in male patients (17/56, 30.4 %) (P=0.011). The rate of MFH and leiomyosarcoma was significantly higher in young patients than that in older patients (6/83, 7.2% vs. 12/703,1.7%) (P＜ 0.05), especially in female patients (4/27,14.8%). Younger male patients were more likely to have a higher incidence of small tumors (T≤4 cm)(24/56,42.9 % vs. 173/703,24.6 % )(P＜0.05)and a lower incidence of big RCC(T＞7 cm) than older patients(12/56,21.4% vs. 295/703,42.0%) (P＜0.05). Conclusion Younger female renal cell carcinoma patients tends to have worseprognosis than older patients, while younger male patients have better prognosis due to different pathology.
