MINI25.02 - A Clinical Study on Intra-Thoracic Chemotherapy of Recombinant Human Endostatin Combined with Cisplatin for Malignant Pleural Effusion (ID 1304)
16:45 - 18:15 | Author(s): Y. Wang
To observe the efficacy and safety of intra-thoracic chemotherapy of recombinant human endostatin (Endostar) combined with cisplatin in the treatment of malignant pleural effusion.
A total of 84 patients with malignant pleural effusion were randomly divided into intra-thoracic chemotherapy of Endostar combined with cisplatin group (combination group) and single cisplatin group (single group). Before treatment, pleural effusion was completely resolved. Combination group was treated with intra-thoracic injection of 40～50 mg cisplatin and 60 mg Endostar twice a week, and 4 times were as a cycle at most. Single group was only treated with cisplatin, and other operations were the same as the combination group. RECIST1.0 hydrothorax evaluation criteria and NCI-CTC AE 3.0 version classification criteria were applied to evaluate the efficacy and adverse reactions, respectively.
The response rates of initially-treated patients in combination group and single group were 63.6% and 40.6%, respectively, and significant difference was presented (X＝2.737, P＝0.022). The response rates of all patients in combination group and single group were 58.1% and 36.6%, respectively, and the difference was significant (X＝4.877, P＝0.019). The progression-free survival (PFS) in combination group was dramatically longer than in single group (95 d vs. 53 d; X＝3.872, P＝0.039). No adverse reactions at degree Ⅳ were observed in all groups. Incidences of adverse reactions including neutropenia, anemia, fatigue and increase of blood pressure in combination group were all higher than in control group, but there was no statistical significance (P＞0.05).
Intra-thoracic injection of cisplatin alone is effective for treating patients with malignant pleural effusion, and its efficacy is better in combination with Endostar. Cisplatin combined with Endostar has a synergistic effect and better safety, being worthy of further popularization in clinic.
