RESUMEN
OBJECTIVES: To report the prevalence of cholesteatoma and related comorbidities in pediatric aerodigestive patients requiring tracheostomy or airway reconstruction procedures. To use study findings to inform clinical management of these complex patients. METHODS: A repository of clinical data drawn from our institution's electronic medical records was queried to identify airway reconstruction (airway) and complex hospital control (control) patient cohorts. Retrospective chart review was then performed to investigate the occurrence of cholesteatoma and related pathologies in these patients, as well as clinical management. RESULTS: The prevalence of cholesteatoma in airway and control patients was 6/374 (1.60 %) and 35/30,565 (0.11 %), respectively. The relative risk of cholesteatoma diagnosis in airway patients was 14.01 (95 % CI 6.06-32.14). Airway patients were more likely than control patients to have pressure equalization tube history (relative risk 3.25, 95 % CI 2.73-3.82). Age at cholesteatoma diagnosis and first surgical intervention was younger in airway compared to control patients (5.43 vs. 8.33, p = 0.0182, and 6.07 vs. 8.82, p = 0.0236). However, time from diagnosis to intervention and extent of surgery were similar between the groups. CONCLUSION: This is the first study to investigate the prevalence of cholesteatoma in the pediatric aerodigestive population. The relative risk of cholesteatoma diagnosis was found to be 14 times higher in patients with tracheostomy or airway reconstruction history. Underlying eustachian tube and palatal dysfunction are likely contributing factors to the elevated risk. Additionally, cholesteatoma in this population was diagnosed and required surgical intervention at a younger age, which may suggest a more aggressive disease course. Providers should maintain a high degree of suspicion for cholesteatoma in this complex population.

Clinical trials frequently include multiple end points that mature at different times. The initial report, typically based on the primary end point, may be published when key planned co-primary or secondary analyses are not yet available. Clinical Trial Updates provide an opportunity to disseminate additional results from studies, published in JCO or elsewhere, for which the primary end point has already been reported.Mosunetuzumab is a CD20xCD3 T-cell-engaging bispecific antibody administered as an off-the-shelf, fixed-duration treatment in an outpatient setting. We report an updated analysis of the durability of response, by investigator assessment, after an overall median follow-up of 3.5 years in patients with relapsed/refractory indolent or aggressive B-cell non-Hodgkin lymphoma (iNHL/aNHL) from the dose-escalation stage of a phase I/II study of mosunetuzumab (ClinicalTrials.gov identifier: NCT02500407). Across dose levels, 65.7% of patients with iNHL and 36.4% with aNHL achieved a complete or partial response to mosunetuzumab. Median duration of response (DoR) in patients with iNHL for all responders was 23.2 months (95% CI, 13.8 to not estimable [NE]), but was not reached in complete responders (95% CI, 21.0 to NE). After a median time on study of 38.9 months, no relapses were observed beyond 26 months in complete responders. In patients with aNHL, median DoR for all responders was 7.8 months (95% CI, 4.6 to 22.8). Among 12 complete responders who progressed postmosunetuzumab treatment and were retreated with mosunetuzumab, 83.3% had an objective response and 58.3% achieved a second complete response. Our study reports the longest follow-up using bispecific antibodies in patients with B-cell non-Hodgkin lymphoma and demonstrates that mosunetuzumab can mediate durable remissions with time-limited treatment.
