Characterizing head and neck cancer survivors' discontinuation of survivorship care.

BACKGROUND: Little is known about cancer survivors who discontinue survivorship care. The objective of this study was to characterize patients with head and neck cancer who discontinue survivorship care with their treating institution and identify factors associated with discontinuation. METHODS: This was a retrospective cohort study of patients diagnosed with head and neck cancer between January 1, 2014, and December 31, 2016, who received cancer-directed therapy at the University of Iowa Hospitals and Clinics (UIHC). Eligible patients achieved a cancer-free status after curative-intent treatment and made at least 1 visit 90+ days after treatment completion. The primary outcome was discontinuation of survivorship care, which was defined as a still living survivor who had not returned to a UIHC cancer clinic for twice the expected interval. Demographic and oncologic factors were examined to identify associations with discontinuation. RESULTS: Ninety-seven of the 426 eligible patients (22.8%) discontinued survivorship care at UIHC during the study period. The mean time in follow-up for those who discontinued treatment was 15.4 months. Factors associated with discontinuation of care included an unmarried status (P = .036), a longer driving distance to the facility (P = .0031), and a single-modality cancer treatment (P < .0001). Rurality was not associated with discontinuation (24.3% vs 21.6% for urban residence; P = .52), nor was age, gender, or payor status. CONCLUSIONS: The study results indicate that a sizeable percentage of head and neck cancer survivors discontinue care with their treating institution. Both demographic and oncologic factors were associated with discontinuation at the treating institution, and this points to potential clinical and care delivery interventions.

Genetic Causes of Hearing Loss in a Large Cohort of Cochlear Implant Recipients.

Understanding genetic causes of hearing loss can determine the pattern and course of a patient's hearing loss and may also predict outcomes after cochlear implantation. Our goal in this study was to evaluate genetic causes of hearing loss in a large cohort of adults and children with cochlear implants. We performed comprehensive genetic testing on all patients undergoing cochlear implantation. Of the 459 patients included in the study, 128 (28%) had positive genetic testing. In total, 44 genes were identified as causative. The top 5 genes implicated were GJB2 (20, 16%), TMPRSS3 (13, 10%), SLC26A4 (10, 8%), MYO7A (9, 7%), and MT-RNR1 (7, 5%). Pediatric patients had a higher diagnostic rate. This study lays the groundwork for future studies evaluating the relationship between genetic variation and cochlear implant performance.

Temporal bone carcinoma: Treatment patterns and survival.

OBJECTIVES/HYPOTHESIS: Carcinomas of the temporal bone are rare, and appropriate treatment, staging, and survival data are limited. This study evaluates clinical characteristics and survival rates for patients with temporal bone carcinoma treated with resection at a single tertiary-care institution, with a focus on the outcomes of patients with locally advanced disease including skull base and/or dural invasion. STUDY DESIGN: Retrospective chart review. METHODS: Demographic, tumor-specific, and survival data were collected for patients with primary carcinomas of the external auditory canal with involvement of the temporal bone from 2003 to 2015. All patients were staged according to the modified Pittsburgh system. Kaplan-Meier and logistic regression analysis were used to calculate factor-specific survival outcomes. RESULTS: Sixty-seven patients met inclusion criteria; 85% were male. There were 43 squamous cell carcinomas (64%) and 24 basal cell carcinomas (BCCs) (36%). Tumor stage was 24 (36%) T2, 12 (18%) T3, and 31 (46%) T4 tumors; 53% had recurrent disease. Surgical management included 49 lateral temporal bone resections and 18 subtotal temporal bone resections. Kaplan-Meier analyses revealed more favorable 5-year survival rates associated with BCC histology (P = .01), lateral temporal bone resection compared to subtotal temporal bone resection (P < .01), lack of immunocompromise (P = .04), and absence of perineural/lymphovascular invasion (P = .01). Multivariate regression analysis did not yield statistically significant results. CONCLUSIONS: Factors predictive of more favorable survival include lack of immunocompromise, BCC histology, absence of perineural/lymphovascular invasion, and disease extent amenable to lateral temporal bone resection. Dural invasion is not an absolute contraindication to surgery, with a subset of patients surviving >5 years. LEVEL OF EVIDENCE: 3 Laryngoscope, 130:E11-E20, 2020.

Pediatric Tracheostomy Decannulation: 11-Year Experience.

OBJECTIVE: To determine the successful decannulation rate with a published pediatric tracheostomy decannulation protocol. STUDY DESIGN: Case series with chart review. SETTING: A single tertiary care institution. SUBJECTS AND METHODS: A chart review was performed for patients aged ≤5 years who underwent tracheostomy. Extracted data included demographic data, indication for tracheostomy, age at tracheostomy and decannulation, comorbidities, and surgical complications. Records were searched for documentation of early decannulation failure (within 1 month of decannulation) or late failure (within 1 year). RESULTS: Forty patients with a tracheostomy aged ≤5 years underwent attempted decannulation during the 11-year study period. Seventeen patients were excluded from the study for documentation of nonprotocol decannulation. The final study population of 23 patients underwent a total of 27 decannulations, 26 of which were performed by protocol. Of the 26 protocol decannulations, 22 were successful, for a failure rate of 15%. CONCLUSION: Twenty-six protocol decannulations were attempted among 23 patients, 4 of which were unsuccessful for an overall failure rate of 15%. This result is consistent with rates reported in other published decannulation protocols. We believe that our protocol minimizes resource utilization in its use of pulse oximetry over polysomnography, while maximizing patient safety and success through the use of capping trials for very young and very small pediatric patients.
