ABSTRACT
【Objective】 To analyze the correlation between the expressions of CD10,CA9 and CD133 and the prognosis of patients with metastatic renal clear cell carcinoma (mccRCC) treated with sorafenib or sunitinib. 【Methods】 A total of 80 mccRCC patients who received sorafenib or sunitinib as first-line therapy were retrospectively enrolled. Immunohistochemical staining (IHC) was performed for CD10,CA9 and CD133 in tumor tissue samples to analyze the correlation between the expression of each marker and clinicopathologic variables. Univariate and multivariate Cox proportional risk models were used to analyze prognostic factors of progression free survival (PFS) and overall survival (OS),and Kaplan-Meier survival analysis was performed for CA9 expression and PFS,OS in the treatment subgroups. 【Results】 Altogether 37 patients (46.25%) had PFS,and the median PFS (mPFS) was 24.9 months (95%CI16.5-33.2 months),while 55 patients (68.75%) died and the median OS (mOS) was 44.2 months (95%CI14.6-73.7). Low expression of CD10 was correlated with high Fuhrman grade (χ2=6.241,P=0.012),lymph node metastasis (χ2=5.952,P=0.015),and the number of metastatic organs ≥2 (χ2=8.205,P=0.004). Univariate analysis showed that Fuhrman grade,number of metastatic organs and lymph node metastasis were the prognostic factors of PFS (P<0.05),while the number of metastatic organs,lymph node metastasis and CA9 expression were the prognostic factors of OS (P<0.05). Multivariate analysis showed that Fuhrman grade was an independent factor of PFS (HR=2.457,95%CI1.126-5.365,P=0.024),and the number of metastatic organs was an independent prognostic factor of OS (HR=1.857,95%CI1.048-3.290,P=0.034). Survival analysis in subgroups showed that high CA9 expression in the sorafenib group was associated with longer OS (HR=0.401,95%CI0.204-0.787,P=0.008). 【Conclusion】 Low expression of CA9 is an non-independent risk factor for OS,while CD10 and CD133 cannot be used as prognostic factors for mccRCC patients. Since mccRCC patients with low CA9 expression have less survival benefit from sorafenib and sunitinib,they can choose target therapy combined with immunotherapy or dual immunotherapy according to the guidelines to improve prognosis.
