Abstract

We have recently described a poly-chemotherapy (GOLF) regimen that: A) is active in colon carcinoma patients as second line of therapy; B) induces high levels of necrosis and apoptosis in colon cancer cells; C) up-regulates the expression and release of heat shock proteins (HSP)-70 and -90 and tumour-associated antigens (2,3); and D) down-regulates tumour cell resistance to the death signals of cytotoxic-T-lymphocytes.These effects represented the rationale for projecting GOLFIG regimen. Here we describe the results of a multi-center translational phase II trial designed to evaluate the toxicity, anti-tumour activity of a novel regimen designated as GOLFIG-1, composed by the GOLF poly-chemotherapy followed by the subcutaneous (sc.) administration of GM-CSF and low-dose IL-2 in colorectal carcinoma patients. The study involved 37 patients (21M and 16F, mean age 62.5 years), 24 of whom had received a previous line of treatment, and 24 had liver involvement. All the patients received biweekly chemotherapy with gemcitabine (1g/m2, day 1 and 15), oxaliplatin (85 mg/m2, day 2 and 16), levo-folinic acid (100 mg /m2, day 1, 2, 15, 16) and 5-Fluorouracil (400 mg/m2 as a bolus, and 800 mg/m2 as 24 hour infusion, days 1, 2, 15, 16). These patients also received sc GM-CSF (100 µg, day 3 to 8) followed by sc IL-2 (0.5 X 106 IUs twice a day from day 9 to 14 and from 17 to 29). The treatment was well tolerated and very active in colon carcinoma patients, with high objective response (64.9%) and disease control rates (97.3%), with an average time to progression of 12.94 months (CI 95%: 9.98-15.91). An immunological study confirmed the immunological response to colon carcinoma antigen, a significant reduction in suppressive regulatory T lymphocytes (CD4+CD25+T-reg) and a significant reduction of VEGF levels reported in a previous study. In conclusion, these results suggest that the GOLFIG regimen exerts strong immunological and anti-tumour activity in colorectal cancer patients. A randomized phase III trials aimed to compare the efficacy of GOLFIG-1 with FOLFOX-4 regimen in patients with advanced colorectal carcinoma is presently ongoing.
