Abstract
Twenty-three patients with pleural mesothelioma stage I-IIA were entered in a study of continuous daily intrapleural infusion of interleukin 2 (IL-2) for 14 days, repeated every 4 weeks. IL-2 was administered according to a groupwise dose escalation schedule (group A, 3 x 10(4); group B, 3 x 10(5); group C, 3 x 10(6); group D, 6 x 10(6); group E, 18 x 10(6); and group F, 36 x 10(6) IU day-1). Each group consisted of at least three patients. Intrapleural administration of IL-2 was associated with acceptable toxicity. All patients were treated on an outpatient basis except for the patients at dose levels E and F. Dose-limiting toxicity was observed at level F, 36 x 10(6) IU daily, and consisted of catheter infection, fever and flu-like symptoms. Intrapleural IL-2 levels were high (> 20,000 IU ml-1) at levels E and F, while serum levels in most patients were not or barely detectable (< 3-30 IU ml-1). Intrapleural IL-2 levels were up to 6000-fold higher than systemic levels. Intrapleural tumour necrosis factor alpha (TNF-alpha) levels varied greatly and did not correlate with IL-2 dosage. Intrapleural mononuclear cells (MNCs) displayed IL-2-induced lymphokine-activated killer (LAK) activity in all patients. Two patients were not evaluable for response owing to catheter-related problems which precluded the delivery of IL-2. Partial response (PR) occurred in 4 of 21 evaluable patients (19%; 95% confidence interval 5-42%) with a median time to progression of 12 months (range 5-37). Stable disease (SD) occurred in seven patients with a median time to progression of 5 months (range 2-7). There were no complete responses (CRs). The median overall survival was 15.6 months (range 3.0-43). No relationship between the dose of IL-2 and response rate was observed. We conclude that IL-2 given intrapleurally is accompanied with acceptable toxicity and has anti-tumour activity against mesothelioma. In view of the refractory nature of the disease IL-2 may be a treatment option for mesothelioma. A formal phase II study is warranted. Based on the observed toxicity, the lack of dose-response relationship and the immunomodulatory effects seen at relatively low-dose IL-2, the recommended dose for a phase II study is 3 x 10(6) IU day-1 using the present treatment schedule.
