Abstract
It has been suggested that paclitaxel and gemcitabine modulate the immune system. This paper reports the safety and efficacy of paclitaxel plus gemcitabine followed by interleukin-2 (IL-2)and granulocyte macrophage colony-stimulating factor (GM-CSF), the PGIG chemobiotherapy, for patients with metastatic melanoma. All patients received 175 mg/m ( 2) paclitaxel on day 1 and 800 mg/m ( 2) gemcitabine on day two. IL-2 and GM-CSF were administered from day 4 to day 8 at a dosage of 2 MIU/m ( 2) and 100 μg, respectively. The PGIG chemobiotherapy was repeated every 21 d. Serum cytokine levels at baseline and at the end of the second cycle were measured via flow cytometry. Twenty-seven patients with metastatic melanoma accepted PGIG chemobiotherapy from August 2009 to March 2011. There were five patients that exhibited a partial response, 14 patients that exhibited a stable response and eight that displayed progressive disease. Therefore, the response rate was 18.5%, and the disease control rate was 70.4%. The median time to progression and median survival were 4 mo and 8 mo, respectively. The one-year and two-year survival rates were 25.9% and 18.5%, respectively. Frequent side effects included chills, fever, arthralgia, rash and pruritus. Among the 13 patients who experienced a rash and pruritus and the 14 patients who did not suffer from this side effect, the response rates and disease control rates were 30.8% vs 7.1% and 77% vs 64.2%, respectively. No relationship between serum IL-6 levels, clinical response, and either skin side effect was observed. The PGIG chemobiotherapy is safe and effective for the treatment of patients with advanced melanoma, but randomized trials are necessary to validate this effect.
