DRIHNC - Dehydration Reduction in Head & Neck Cancer

Among patients with cancer of the H\&N or esophagus, complications related to dehydration are fairly common, and can result in requiring IV fluid support in an ACC setting, ED or even inpatient admission. By instructing participants to drink a reasonable amount of a common electrolyte-rich energy drink from the initiation of treatment through its completion, the hypothesis will be tested that this inexpensive and easily administered preventative strategy can significantly decrease the rate of ACC and ED visits. The objectives of this study are to decrease the frequency of ACC visits during the course of radiation therapy and decrease the frequency of ED visits during the course of radiation therapy. The study team also seeks to decrease the incidence of orthostatic vital signs during the course of radiation therapy and decrease the number of days of missed treatments due to radiation toxicity during the course of radiation therapy. In the pilot cohort, participants will be given Gatorade G2 to drink daily during the course of radiation, along with standard of care nutritional support from dietitians. The randomized Phase 2 cohort has two study groups. Group 1 will receive standard of care nutritional support. Group 2 will receive standard of care nutritional support plus the study agent, Gatorade G2.
