[Intraperitoneal administration of OK-432 and rIL-2 in a case of peritonitis carcinomatosa with chronic renal failure].

Recombinant interleukin-2 (rIL-2) was administered intraperitoneally for 15 days, 2 days after intraperitoneal administration of Streptococcal preparation OK-432 to a patient of peritonitis carcinomatosa occurred eight months after second look operation, in which residual tumor could not be removed completely. The patient had been maintained by hemodialysis three times a week for over ten years. Combination chemotherapy using CDDP and Ifosfamide, or CDDP and THP-Adriamycin had not been effective to control rapidly increasing ascites. Negative cytological exam, was achieved on day 7 and ascites disappeared by day 15. No severe side effects including fluid retention were observed. Fever up was controllable by Indomethacin. Flow cytometric analysis revealed dominant (73%) CD4+, CD29+ helper inducer subset, while CD4+, CD45RA+ was 6%, in the lymphocytes in ascites on day 8. It was suggested that intraperitoneal administration of rIL-2 after OK-432 was safe and effective for peritonitis carcinomatosa with chronic renal failure.
