Methodology to screen and evaluate cost/survival of anticancer drugs in advanced/metastatic gastrointestinal cancers.
196 Background: There is a paucity of methods to screen cost/survival of anticancer drugs in 1st-line advanced/metastatic (adv/met) gastrointestinal (GI) cancers. Methods: Average whole prices (AWP) in United States dollars (US $) of evaluated drugs for the entire course were divided by previously reported median survival gain in days. Generic drugs were given flat total costs of up to $750. A 100% crude score was assigned to cost/survival/day < $25 and 0% to cost/survival/day $750. Results were expressed as % scores of cost/progression-free-survival (cost/PFS) or cost/overall survival (cost/OS). Guidelines were suggested for corrections; lack of OS - 10%, adverse effects (AEs) - 0 -15%, Quality of life (QoL) - 0-10% and administration and preparation (A and P) - 0-10%. Results: Generic drugs scored 80%-90% in pancreatic and biliary followed by Trastuzumam 60% in gastric and Bevacizumab 0-40% in colon cancers (Table 1). Conclusions: Methodology based on limits on cost/survival/day was developed to screen anticancer drugs in GI cancers. Generic drugs in bilary and pancreatic cancers scored the highest.
