BACKGROUND: Cell-free and concentrated ascites reinfusion therapy (CART) has been suggested to be able to treat malignant ascites more safely and effectively with chemotherapy because of its ability to retain serum protein and albumin. Although the characteristics of cancer types and CART and the clinical implications of combination therapy with antitumor agents are becoming widespread, there are limited reports on its efficacy and complications.

METHODS: In this prospective observational national post-marketing study, 128 patients with malignancies received 300 CART sessions at 22 centers. After excluding other malignancies, the patients were divided into four groups: gynecological malignancies with chemotherapy (GYC+; 18 cases and 36 times) and without chemotherapy (GYC-; 35 cases and 52 times), and gastrointestinal malignancies with chemotherapy (GIC+; 8 cases and 16 times) and without chemotherapy (20 cases and 58 times).

RESULTS: There were significant reductions in the body weight in all groups and significant reductions in abdominal circumference and significant improvements in the diet and Eastern Cooperative Oncology Group performance status only in the GYC+ group. The total serum protein and albumin increased significantly in all groups, except for the GIC+ group, before and after CART. There was no significant difference in the presence or absence of antitumor medication.

CONCLUSION: With CART, there were differences in the improvement of the clinical symptoms between malignancy groups. The combination of CART and antineoplastic agents may be as safe as CART alone in cases of exudative malignant ascites.
