Summary
Temporal bone malignancy is rare but challenging. Middle ear involvement is a key negative prognostic factor, highlighting the need for early, radical surgical resection and multidisciplinary care.
Area of Science:
- Oncology
- Otorhinolaryngology
- Surgical Pathology
Background:
- Lateral temporal bone malignancy is a rare and challenging oncological condition.
- Effective management requires understanding prognostic indicators.
- Multidisciplinary care is crucial for optimal outcomes.
Purpose of the Study:
- To analyze prognostic indicators in temporal bone malignancy.
- To evaluate the outcomes of multidisciplinary care over 17 years.
- To inform contemporary oncological management strategies.
Main Methods:
- Retrospective cohort study of 48 patients diagnosed between 2000 and 2017.
- Inclusion of histopathologically confirmed cases of temporal bone malignancy.
- Univariate and multivariate analyses of prognostic factors and survival rates.
Main Results:
- Squamous cell carcinoma was the most common malignancy (71%).
- Overall 5-year disease-specific survival was 52.4%, and recurrence-free survival was 53.5%.
- Middle ear involvement was a significant negative prognosticator on multivariate analysis for both survival outcomes.
Conclusions:
- Temporal bone malignancies encompass diverse pathologies.
- Recurrence-free survival rates are comparable to international data but remain low.
- Radical surgical resection at initial presentation and multidisciplinary input are recommended, with middle ear involvement being a critical negative prognostic factor.
