Some readers have raised the possibility Studies conducted prior to the mid-1990s tended that the chemotherapy and radiation were benefi- to be small and underpowered, which has led to cial mainly because of suboptimal surgery in this a variety of conflicting results. In locally advanced disease, the Gastrointesti- nal Tumor Study Group (GITSG) randomised ADVANCED DISEASE 227 patients to three arms: radiotherapy alone, or radiotherapy at two different dose levels Palliative therapy does make a meaningful dif- given with chemotherapy (5-FU). Two studies have investigated the GASTROINTESTINAL CANCERS 121 need for chemoradiotherapy versus chemotherapy justified by the occasional tumour response that alone, with conflicting results. Single agent therapy with 5-FU in a two-arm randomised study of 191 patients, has been used as the control arm for multiple found no advantage for combined therapy ver- randomised trials, with the assumption that 5-FU sus chemotherapy alone, while GITSG19 reported was at worst a toxic placebo, thus if a new that overall survival was improved with the addi- experimental regimen were shown superior to tion of radiation to chemotherapy in a two-arm 5-FU, it would indeed have improved efficacy study of 43 patients. The Burris trial established gemc- gested a benefit to post-operative chemotherapy itabine as a new standard of care in this setting.

Some clients cannot respond to glucagon because glycogen maintain blood glucose levels. Glucagon and epinephrine, the stores are depleted by such conditions as starvation, adrenal insuffi- dominant counter-regulatory hormones, act rapidly because they ciency, or chronic hypoglycemia. The hyperglycemic effect of are activated as soon as blood glucose levels start declining. People with diabetes who develop hypoglycemia may have Caution is needed in the treatment of hypoglycemia. Although impaired secretion of these hormones, especially those with type the main goal of treatment is to relieve hypoglycemia and restore the 1 diabetes.

Health care personnel caring for the client creases tachycardia, a common sign of hypoglycemia, and may should avoid giving excessive amounts of glucose.
