The Sound and the Fury: What’s the Issue?
Immunotherapy has revolutionized cancer treatment, but like any medical intervention, it comes with its own set of challenges. One such challenge is hearing loss, a side effect that has been largely overlooked until now.
This systematic review delves into the rare but significant issue of hearing loss related to Immune Checkpoint Inhibitors (ICIs), particularly in melanoma patients.

The Source Article's Abstract
Immune checkpoint inhibitors (ICIs) are related to various immune-related adverse events (irAEs). However, the knowledge is limited with rare irAEs like hearing loss. Therefore, we evaluated the characteristics, presentation, and treatment of ICI-related hearing loss by reviewing the individual patient data from the previous studies.
We conducted a systematic search of the Web of Science, PubMed, and Embase databases for studies published until 17 November 2022.
A total of 38 patients were included. Melanoma was the most frequent diagnosis (73.7%). The median time from ICI initiation to hearing loss development was 3 months. The hearing impairment was secondary to bilateral sensorineural hearing loss (SNHL) in 24 (68.6%) patients, and at least one other irAE accompanied the hearing loss in 24 patients. Hearing loss significantly improved in 45.7% of the patients. The overall response rate and disease control rate were 67.6% and 85.3%, respectively.
We observed that most cases of ICI-related hearing loss were reversible, observed in patients with melanoma, accompanied by other irAEs, and associated with a high response rate to ICIs.

What the Numbers Say: Key Findings
The study included 38 patients, mostly diagnosed with melanoma. The median time from ICI initiation to hearing loss was 3 months, and the condition was reversible in nearly half of the cases.
Interestingly, the hearing impairment was often accompanied by other immune-related adverse events, making it a multi-faceted issue that requires comprehensive management.
PP-ICONS: A Quick Evaluation
- Problem: Hearing loss in melanoma patients undergoing ICI treatment.
- Patient or Population: 38 patients, mostly with melanoma.
- Intervention: Immune Checkpoint Inhibitors.
- Comparison: Not applicable, as this is a systematic review.
- Outcome: Hearing loss was reversible in 45.7% of the patients.
- Number of Subjects: 38 patients.
- Statistics: Overall response rate and disease control rate were 67.6% and 85.3%, respectively.
Implications and Future Directions
The study highlights the need for further research to define the true prevalence of ICI-related hearing loss and its optimal diagnosis and management.
As ICIs find more applications in earlier treatment lines, the number of survivors experiencing this side effect is expected to increase, making it a pressing issue for the medical community.
