Randomized Trial Comparison of Ototoxicity Monitoring Programs

Research objectives are to compare the effectiveness of ototoxicity monitoring implemented using Comp-VA or usual care with regard to (1) improving Veterans' hearing and quality of life outcomes, (2) assisting oncologists in pre-treatment counseling and therapeutic planning and (3) increasing use of post-treatment rehabilitative services. The investigators plan to recruit a total of 320 Veterans undergoing cisplatin chemotherapeutic treatment over 4 years and 120 control subjects. Program Evaluation: Hearing testing prior to treatment will be done in order to establish eligibility, enroll and randomize each subject into one of two study arms. At 5 weeks and at one year post-randomization hearing will be re-tested in order to obtain an estimate of longitudinal trends in hearing and quality of life assessment. Use of audiological services following treatment from the randomized subjects will be tracked. Finally, data will also be collected at each treatment interval to track use of counseling tools and oncology personnel treatment decisions. Serial measurements from subjects receiving cisplatin prior to treatment who are randomized to: Comp-VA group will get a screening hearing test prior to treatment, at each treatment interval and at one-month post-treatment. Auditory testing will be done on or near the Chemo Unit and will include otoscopy, immittance testing, and a hearing testing done by the Veteran using a self-testing procedure, and may be tested using distortion product otoacoustic emissions (DPOAEs), if they cannot take a reliable hearing test. Usual care group will receive a full audiometric evaluation (otoscopy, immittance testing, air conduction and bone conduction hearing testing, speech audiometry, and distortion product otoacoustic emissions, DPOAEs) scheduled in the audiology clinic sound booth according to Audiology Service ototoxicity monitoring protocols. Testing will be arranged according to availability of appointments and patient convenience. Additionally data will also be collected from control subjects who are similar in age and are tested at intervals similar to the chemotherapy subjects.
