14133 Twenty consecutive prospectively registered patients with refractory or Stage IV gastric cancer were treated with GFLIP (Bruckner el al ASCO 2002;2005). The last 10 upon relapse were treated with GFL[OX]T and Bevacizumab, substituting oxaliplatin (OX) 30→40 mg/M 2 , taxotere (T) 30→40 mg/M 2 for cisplatin in the q2wk schedule. One or both regimens produced; objective responses for 15 patients including 5 complete (radiologic, tumor markers, PET responses) and 2 surgical downstaging resulting in resection or successful completion surgery; 3 patients had stable disease greater than 4 months with subjective benefit, gemcitabine was given at 400→500 mg/M 2 as tolerated (→), 2 failed both regimens. One-year actuarial survival was 75%, two-year survival was 25%. All 20 lived more than six months. The level of activity, multiple crossover responses, responses with both regimens, a number of long remissions (long survival after 5FU cisplatin and GFLIP failed) and clinical downstaging allowing further surgery identify both regimens either individually or in sequence as deserving systematic investigation. The utility of low doses (responses), unusual clinical benefits, quality of life and safety offer possible advantages compared to standard dose regimens.This strategy appears to reduce and delay the limiting toxicity of the irinotecan (I) 80 mg/M 2 , cisplatin (P) 40 mg/M 2 OX/T which are conventionally treatment limiting drugs. The regimens were designed based on laboratory evidence of low dose drug interaction including reversal of resistance to conventional drugs (applicable to both pancreatic and gastric cancer (Janat et al, Amer Asso Cancer Res 1999). After clinical demonstrations of high response rates and reversal of resistance against refractory pancreatic cancer (Bruckner et al, AntiCancer Res and ASCO 2005). The regimens were offered to patients with recurrent previously treated and refractory gastric cancer and then based on initial exceptional responses to high risk patients with poor prognosis due to clinical complications of their gastric cancer.
