Plain English Summary

Background and study aims
Hearing loss is a serious and potentially irreversible side-effect of platinum-based chemotherapy. Current management involves changing or reducing chemotherapy medications if hearing loss is detected. However, early detection is difficult as it currently relies on hearing tests performed in sound-proof booths in Audiology Departments when patients report symptoms of hearing loss or tinnitus (ringing in the ears). This is problematic since arranging such tests adds to the onerous schedule for cancer patients and hearing loss may be only detected after irreversible damage has already occurred. This study aims to investigate the feasibility of:
1. Monitoring hearing more closely throughout chemotherapy treatment in the cancer department itself using soundproof headphones and a tablet-based hearing test that is partly self-administered.
2. Measuring prestin and otolin-1 blood levels as possible markers of impending hearing loss from scheduled blood tests to help predict which patients are likely to develop hearing loss.

Who can participate?
Patients aged 13-40 years treated with platinum-based chemotherapy for bone sarcomas or testicular cancer at the University College London Hospital Macmillan Cancer Centre and St Bartholomew’s Hospital will be invited to participate. To be able to take part, patients must have normal hearing at the start of chemotherapy and no history of middle ear disease or previous platinum-based chemotherapy.

What does the study involve?
Patients will receive their cancer treatment as per usual by their own medical teams and have a routine hearing test in the Audiology Department at the beginning and end of their chemotherapy treatment. Patients that have consented to take part in the study will be visited by the audiologist or clinical research practitioner during routine cancer hospital appointments or in the hospital ward. These visits are scheduled at the start of chemotherapy, before and after each chemotherapy cycle and finally 2 weeks after completion of chemotherapy treatment. During the visits, the patients will be asked and supported to undertake the tablet-based hearing test and an automatic hearing test called the distortion production otoacoustic emission (DPOAE) test. During the the first and last visits patients will also be asked to complete quality of life questionnaires. Those who experience tinnitus will be asked to complete a questionnaire. For patients with sarcoma, from their routine blood tests (taken five times throughout treatment) samples will also be processed for prestin and otolin-1 levels.

What are the possible benefits and risks of participating?
Participants will have their hearing tested more frequently than standard. Of potential benefit, the study may raise earlier concerns about hearing loss, tinnitus, or loud sounds. The research team will support the participants throughout the study and will ensure discussion of hearing test results with the and the medical team throughout.

Scientific titleMonitoring ototoxicity in patients undergoing treatment with platinum-based chemotherapy for sarcoma and testicular cancer using tablet-based self-administered audiometry and serum biomarkers
Study hypothesisThe study addresses the following main questions:
1. Is it feasible to conduct out-of-booth tablet-based self-administered audiometry to monitor ototoxicity in patients undergoing treatment with platinum-based chemotherapy for sarcoma and testicular cancer?
2. Can prestin and otolin-1 be used as a biomarker for platinum-based chemotherapy-induced ototoxicity?

ConditionPlatinum-based chemotherapy for sarcoma or testicular cancer
InterventionTablet-based self-administered audiometry (TBSA) and distortion product otoacoustic emissions (DPOAE) will be conducted in a quiet room at the hospital. Ambient noise levels in the room will be recorded to ensure they do not exceed 40 dBSPL on average across the tested frequencies (500Hz, 1000Hz, 2000Hz, 4000Hz and 8000Hz). Tablet-based hearing tests that are partly self-administered and DPOAE tests will be performed at baseline, directly before and after each chemotherapy cycle and at a final visit 2-4 weeks after cycle 4. TBSA involves the Shoebox mobile device (iPad) with inbuilt calibrated audiometry. This equipment can be easily moved depending on where the participant is i.e., in the ward, or at their day-care appointment. TBSA includes the test frequencies: 250Hz, 500Hz, 1000Hz, 2000Hz, 3000Hz, 4000Hz, 6000Hz, 8000Hz, 10000Hz, 12500Hz and 16000Hz. The audiologist places the circum-aural headphones onto the patient's ears to ensure that they are correctly placed. Supported by the researcher, the participant uses the iPad screen to demonstrate whether they hear the stimuli. There is a touch “play” button that needs to be dragged into one of two options, the “heard” option or “unheard” which are depicted by green and red symbols respectively. The participant is reminded that not every press of the play button will present a sound i.e., sometimes it will and sometimes it will not. The researcher observes the participant’s use of TBSA and records the time taken to complete the TBSA. DPOAE testing with the Otodynamics Otoport Flexi OAE device involves the use of a small soft probe that is inserted into the patient’s ear. The patient is advised to remain still and quiet for this test. The total testing time is approximately 30 minutes.

Primary outcome measureProportion of patients that are compliant with the planned tablet-based self-administered audiometry schedule measured at each scheduled study visit (i.e., baseline, pre-cycle, and post-cycle and at a final visit 2-4 weeks after their final cycle)
Secondary outcome measures1. Changes in pure-tone and high-frequency hearing levels measured using TBSA from baseline to scheduled study visits at the day before and at day 3 of each chemotherapy cycle and at a final visit 2-4 weeks after the final cycle
2. Changes in distortion product otoacoustic emissions (DPOAE) measured with handheld OAE device, Otoport Flexi OAE, from baseline to scheduled study visits at the day before and at day 3 of each chemotherapy cycle and at a final visit 2-4 weeks after the final cycle
3. Changes in hearing-related quality of life (QoL) measured with the HEAR-QL and Tinnitus Functional Index (TFI) at baseline, pre- and post-cycle (if participant reports a history of tinnitus within 2 weeks of visit), and at a final visit 2-4 weeks after the final cycle. Please note TFI is only measured in adults. There is no equivalent for children and adolescents, therefore will not be measured in this age group
4. For sarcoma patients only, serum prestin and otolin-1 levels measured in blood samples taken at baseline, pre- and post-cycle and at a final visit 2-4 weeks after the final cycle
