Abstract

Despite the efficacy of IL-2 in the treatment of metastatic renal cell carcinoma (RCC), the prognosis of patients with synchronous metastases still remains poor. Nephrectomy itself, as well as other surgical operations, may further suppress the antitumor immune response. Previous studies suggested that the preoperative injection of IL-2 may neutralize surgery-induced lymphocytopenia in advanced colon cancer. On this basis, a pilot randomized study was performed in an attempt to evaluate the effects of a preoperative administration of IL-2 on postoperative lymphocyte numbers and on the survival in advanced RVV patients with more than 3 synchronous metastases. The study included 20 consecutive patients, who were randomized to receive nephrectomy alone or nephrectomy plus preoperative subcutaneous immunotherapy with IL-2 (18 million IU/day for 3 days). Then, all patients underwent postoperative immunotherapy with IL-2 (6 million IU/day for 5 days/week for 6 weeks). Surgery-induced lymphocytopenia was completely abolished by IL-2 preoperative injection. The frequency of postoperative complications was significantly higher in controls than in patients preoperatively treated with IL-2. On the contrary, significant differences between control and patients preoperatively treated with IL-2 were observed neither in the clinical response to IL-2 immunotherapy, nor in the percent of 1-year survival. The results of this preliminary pilot study would suggest that IL-2 preoperative immunotherapy may neutralize surgery-induced lymphocytopenia and reduce the postoperative complications in RCC patients with synchronous metastases, without, however, influencing their prognosis in terms of survival time.
