Four patients with small residual ovarian carcinoma following treatment with cisplatin, doxorubicin, and cyclophosphamide have subsequently received 57 courses of ip cisplatin. Cisplatin (120-270 mg in 2 L of Ringer's lactate) was administered via Tenckhoff catheter, with a dwell time of 15-20 mins. Courses were given weekly for 12 weeks, with response documented by laparoscopy or laparotomy prior to and following the trial. With a dwell time of 20 mins, 75% +/- 5% (mean +/- SD) of platinum was recovered. With 120 mg of cisplatin and a dwell time of 20 mins, total plasma platinum peaked at 1.23 +/- 0.42 microgram/ml and by 8 hrs decreased to 0.67 +/- 0.12 microgram/ml. Filterable (non-protein-bound) platinum peaked at 0.73 +/- 0.21 microgram/ml and by 8 hrs fell to 0.03 microgram/ml. Excretion rate paralleled the filterable plasma curve, peaking at 40 mins; 30% +/- 7% of absorbed drug was recovered in urine within 24 hrs. Renal clearance of filterable platinum was 106 +/- 20 ml/min. Creatinine clearance was 76 +/- 7 ml/min. Three responses, one complete and two partial, were noted. Zero to two episodes of vomiting occurred in each course. One patient had a creatinine clearance decrease to 40 ml/min, one had two episodes of thrombocytopenia, and one had mild abdominal pain with a cisplatin dose of greater than or equal to 210 mg. No neurotoxicity, catheter infection, or peritonitis was encountered.
