Raltitrexed-eloxatin salvage chemotherapy in gemcitabine-resistant metastatic pancreatic cancer

Limited information on salvage treatment in patients affected by pancreatic cancer is available. At failure, about half of the patients present good performance status ( PS) and are candidate for further treatment. Patients > 18 years, PS >= 50, with metastatic pancreatic adenocarcinoma previously treated with gemcitabine- containing chemotherapy, and progression- free survival ( PFS) < 12 months received a combination of raltitrexed ( 3 mgm (-2)) and oxaliplatin ( 130 mgm (-2)) every 3 weeks until progression, toxicity, or a maximum of six cycles. A total of 41 patients received 137 cycles of chemotherapy. Dose intensity for both drugs was 92% of the intended dose. Main grade 42 toxicity was: neutropenia in five patients ( 12%), thrombocytopenia, liver and vomiting in three ( 7%), fatigue in two ( 5%). In total, 10 patients ( 24%) yielded a partial response, 11 a stable disease. Progression- free survival at 6 months was 14.6%. Median survival was 5.2 months. Survival was significantly longer in patients with previous PFS 46 months and in patients without pancreatic localisation. A clinically relevant improvement of quality of life was observed in numerous domains. Raltitrexed oxaliplatin regimen may constitute a treatment opportunity in gemcitabine- resistant metastatic pancreatic cancer. Previous PFS interval may allow the identification of patients who are more likely to benefit from salvage treatment.
