Phase I clinical trial of hepatic arterial infusion of cisplatin in combination with intravenous liposomal doxorubicin in patients with advanced cancer and dominant liver involvement

We conducted a phase I study of hepatic arterial infusion (HAI) cisplatin and systemic chemotherapy in patients with advanced cancer and dominant liver involvement. Patients were treated with HAI cisplatin 100-125 mg/m(2) (and 3,000 IU heparin) intraarterially and liposomal doxorubicin (doxil) 20-35 mg/m(2) IV (day 1) every 28 days. A 3 + 3 study design was used. Thirty patients were treated (median age, 56 years). Diagnoses were breast cancer (n = 11), colorectal cancer (n = 8), ocular melanoma (n = 4), and other (n = 7). The median number of prior therapies was 5. The maximum tolerated dose (MTD) was at the 100/35 mg/m(2) level. Dose-limiting toxicities were Grade 4 neutropenia (2 of 4 patients), and Grade 4 thrombocytopenia (n = 1) at the cisplatin 125 mg/m(2) and systemic doxil 35 mg/m(2) dose level. The most common toxicities were nausea/vomiting and fatigue. Of 24 patients evaluable for response, 4 (17%) had a partial response (PR) and 7 (29%) had stable disease (SD) for a parts per thousand yen4 months. Of the 11 patients with breast cancer, 3 (27%) had a PR and 5 (45%) had SD for a parts per thousand yen4 months. Of 4 patients with ocular melanoma, 1 had a PR and 1 SD for 4 months. One patient with hepatocellular carcinoma had SD for 4 months. Of 12 evaluable patients treated at the MTD, 2 (17%) had a PR and 5 (42%) had SD. The MTD was HAI cisplatin 100 mg/m(2) and systemic doxil 35 mg/m(2). This regimen demonstrated antitumor activity, especially in breast cancer.
