Clinical Trial Summary

The purpose of this study is to determine the cost-effectiveness of vocal rehabilitation with reinforced inter-tracheoesophageal voice prosthesis versus standard voice prosthesis in case of repeated intra-prosthetic leakage in total laryngectomy patients.

This is a one year medico-economic study involving patients carrying a standard voice prosthesis implant and having undergone 2 successive prosthesis replacements within 3 months of interval and/or requiring at least 4 changes in the last 12 months, for intraprosthetic leakage.

Eligible subjects will be randomized in 2 groups: reinforced prosthesis with silver coating and double valve (Dual Valve) or standard prosthesis (single unreinforced valve), of the same model as the prosthesis previously implanted in the patient.

Description:

Prosthetic voice rehabilitation is a widespread practice that allows the patient to resume phonation quickly after total laryngectomy/total pharyngolaryngectomy/total circular pharyngolaryngectomy.

When the longevity of the implant is abnormally short (less than 3 months), the multiplication of changes is likely to increase the risk of overall morbidity related to maintaining the functionality of the voice prosthesis and to alter the patient's quality of life.

Reinforced innovative prostheses, currently not supported by the French Social Security, delay the occurrence of intraprosthetic leakage compared to standard prostheses.

This study assesses the economic efficiency from a societal perspective and a one-year time horizon, from vocal rehabilitation with reinforced inter-tracheoesophageal prosthesis versus standard voice prosthesis in case of intra-tracheal leakage in total laryngectomy patients.

Patients are randomized in 2 arms. Arm A usual care with reinforced prosthesis, or arm B usual care with standard prosthesis. Each patient is followed during 12 months.

Outcome

Type	Measure	Description	Time frame	Safety issue
Primary	Incremental Cost-Effectiveness Ratio (cost per avoided prosthesis change), based on a societal perspective, comparing the use of a reinforced voice prosthesis to the use of a standard prosthesis	Effectiveness will be measured by the mean of number of prosthesis changes in each arm. Costs will be measured by 1) Outpatient resource consumption collected in a declarative patient questionnaire and 2) Hospital care resources using the database of the Medicalised Information System Program of each recruiting site	12 months
Secondary	Incremental cost-utility ratio, based on a societal perspective, comparing the use of a reinforced voice prosthesis to the use of a standard one	Utility will be measured by Quality Adjusted Life Year (QALYs) as estimated from responses to the Euroqol-5 Dimensions (EQ-5D 5L) health-related quality of life questionnaire. The questionnaire focuses on 5 dimensions: mobility, personal autonomy, current activities, pain/discomfort and anxiety/depression. For each of these dimensions, 5 answers are possible.; Cost will be measured as described in the Primary Outome Measure	12 months
Secondary	Quality of life using Euroqol-5 Dimensions (EQ-5D) questionnaire	Score of EQ-5D 5L. health-related quality of life questionnaire. The questionnaire focuses on 5 dimensions: mobility, personal autonomy, current activities, pain/discomfort and anxiety/depression. For each of these dimensions, 5 answers are possible, each answer corresponds to a score ranging from 1 to 5.	Baseline, 3 months, 6 months, 9 months and 12 months and at each voice prosthesis replacement
Secondary	Quality of life using the European Organization for Research and Treatment of Cancer (EORTC) Quality of Life Questionnaire-Core 30 (QLQ-C30)	Score of the QLQ-C30 questionnaire, including 30 questions assessing some aspects of the quality of life of cancer patients.
