Effects of pirarubicin and mitoxantrone for bladder cancer perfusion chemotherapy on the expression of malignant molecules in serum and lavage fluid

Objective: To study the effects of pirarubicin and mitoxantrone for bladder cancer perfusion chemotherapy on the expression of malignant molecules in serum and lavage fluid. Methods:Patients with advanced bladder cancer who underwent bladder cancer perfusion chemotherapy in our hospital between March 2015 and December 2017 were selected and randomly divided into the THP group who accepted pirarubicin perfusion chemotherapy and the MTZ group who accepted mitoxantrone perfusion chemotherapy. The serum was collected before and after chemotherapy to determine the contents of tumor markers in serum;the lavage liquid was collected after chemotherapy to determine the contents of malignant molecules. Results:Compared with those of same group before chemotherapy, CXCL5, VEGF, CYFRA21-1, DKK1 and DKK3 contents in serum of both group of patients decreased chemotherapy, and CXCL5, VEGF, CYFRA21-1, DKK1 and DKK3 contents in serum of MTZ group after chemotherapy were lower than those of THP group;ILP-2, CyclinD1, Twist, EpCAM and MMP2 contents in lavage liquid of MTZ group were significantly lower than those of THP group whereas Bad, Bax, TRAIL, FasL, E-cadherin and TIMP4 contents were significantly higher than those of THP group. Conclusion: Mitoxantrone for bladder cancer perfusion chemotherapy can be more effectively than pirarubicin to regulate the expression of malignant molecules.
