Precision Antifungal Treatment Significantly Extends Voice Prosthesis Lifespan in Patients Following Total Laryngectomy.

ABSTRACT: Indwelling silicone valves called voice prostheses (VPs) are the gold standard for speech rehabilitation in patients with laryngeal cancer following total laryngectomy. Reported VP lifespans amongst these patients are highly variable but when devices fail patients experience loss of voice and an increase risk of chest infection. Early failure of VP is a current clinical concern that is associated with regular hospital visits, reduced quality of life and associated medical cost. Poly-microbial biofilms comprised of both bacterial and fungal microorganisms readily colonize VPs and are linked to loss of device performance and its early failure in addition to providing a reservoir for potential infection. Our detailed analysis of poly-microbial biofilm composition on 159 early failing VPs from 48 total laryngectomy patients confirmed Candida albicans as the predominant fungal species and Staphylococcus aureus as the most common bacterial colonizer within our patient cohort. Using a combination of microbiological analysis, patient data and a high-throughput antifungal test assay mimicking in vivo conditions we established an evidence based precision antifungal treatment approach to VP management. Our approach has allowed us to implement a personalized VP management pathway, which increases device in situ lifespan by an average of 270%. Our study represents a significant step forward in both our understanding of the cause of VP failure and a new effective treatment pathway that offers tangible benefit to patients.

Project description:BackgroundTotal laryngectomy (TL) results in permanent functional changes requiring rapid development of complex new skills. A significant portion of this learning happens in the acute post-surgical stage. There is increasing interest in enhanced recovery after surgery (ERAS) protocols in TL; however, implementation has been difficult. COVID-19 has placed significant pressures on acute services, requiring rapid service changes for TL patients.AimsTo understand the acute patient experience of having a TL both before and during COVID-19.Methods & proceduresSemi-structured interviews using a pre-designed topic guide were conducted with 10 people who had undergone a TL within the last 2 years. Participants were recruited by their speech and language therapists using purposive sampling. Braun and Clarke's iterative approach to data collection and thematic analysis was used to generate key themes from the data.Outcomes & resultsThematic analysis identified four main themes: (1) pre-operative information-giving: 'it was just words'; (2) decision-making influences: 'I just wanted them to get it all out and get it over with'; (3) coping with adjustment to the new normal: 'this is part of me now'; and (4) the importance of relationship-building: 'when you've had something like this, you need some care and understanding'.Conclusions & implicationsThe need for an individualized approach to TL intervention which incorporates medical and psycho-social approaches from pre-treatment to acute discharge is vital. ERAS models should be reviewed to shift beyond the medical model alone. Rapid service changes due to COVID-19 did not contribute any major changes to the acute patient-reported experience.What this paper addsWhat is already known on the subject We know that ERAS protocols have the potential to improve patient outcomes following TL. However, the research does not consider anything other than the early oral feeding debate and it has therefore been difficult to implement ERAS protocols in current service models. COVID19 required head and neck cancer services to make quick changes to surgical pathways, with the potential that some ERAS protocols had been adopted inadvertently. In order to understand the impact of this, we need to understand the patient experience following TL both before and during COVID19. What this paper adds to existing knowledge This paper used qualitative interviews to understand the acute patient experience following TL both during and before COVID19. Findings from these interviews highlighted that people were on the most part, well prepared for the functional changes they would experience after surgery. However, people felt there were gaps in service delivery at the pre-treatment and early discharge home period. Overall, the gaps identified were from a more psycho-social need suggesting that future ERAS models of care should consider both medical and psycho-social principles to enhance patient experience and outcome. What are the potential or actual clinical implications of this work? Pre-treatment services provided to people who have a TL could be reviewed to help maximize long-term adjustment to life. Areas which could be reviewed include the method and mode of information delivery. Further work needs to be done in partnership with community services to improve the immediate discharge home experience.

Project description:Importance:Voice prosthesis (VP) device life is a limiting factor of tracheoesophageal (TE) voice restoration that drives patient satisfaction, health care costs, and overall burden. Historic data suggest that TE VPs have an average device life of generally 3 to 6 months, but these data are typically derived from small samples using only 1 or 2 devices. Objective:To reexamine current device life in a large, contemporary cancer hospital in the United States that uses a wide assortment of VPs. Design, Setting, and Participants:This retrospective observational study included 390 laryngectomized patients with a tracheoesophageal puncture (TEP) who had VP management at MD Anderson Cancer Center between July 1, 2003, and December 31, 2013. Main Outcomes and Measures:Tracheoesophageal voice-related outcomes were: (1) device life duration to VP removal, and (2) treatment-related and prosthetic-related factors influencing device failure. Primary independent variables included treatment history (extent of surgery and radiation history), VP type (indwelling vs nonindwelling, size, specialty features), and reason for removal (leakage, complication, other). Duration was examined using Kaplan-Meier analysis. Disease, treatment, and patient-specific factors were analyzed as predictors of duration. Results:Overall, 3648 VPs were placed in the 390 patients (median [range] age, 62 [34-92] years). Indwelling prostheses accounted for more than half (56%) of the devices placed (55%, 20-Fr diameter; 33%, 8-mm length). More than two-thirds (69%) of prostheses were removed because of leakage, while the rest were removed for other reasons. Median device life was 61 days for all prostheses. Indwelling and nonindwelling VPs had median device lives of 70 and 38 days, respectively. There was no significant difference between specialty prostheses compared with standard devices (median duration, 61 vs 70 days, respectively). The Provox ActiValve (Atos Medical) had the longest life. Neither radiation therapy nor extent of surgery had a meaningful impact on device life. Conclusions and Relevance:Our data suggest that VP duration demonstrates a lower durability than historically reported. This may reflect the intensification of treatment regimens that complicate TEP management in an era of organ preservation; however, further investigation is needed.
