Study Details

Study Description

Brief Summary

This is a phase 1b, multicenter, non-randomized prospective study involving an innovation phase (IDEAL-1) followed by a prospective development phase (IDEAL-2A) designed to evaluate the safety and feasibility of oral/oropharyngeal reconstruction with the external pudendal free flap in two groups of patients.

A maximum of 40 patients (20 patients per group) will be included in this IDEAL-1/2A phase study.

Stage IDEAL-1: Innovation phase. The main objective is to evaluate the feasibility in terms of limiting surgical complications of a STEPA flap reconstruction in two groups of patients (Cohort: Male, Female).

Stage IDEAL-2A: Prospective development phase. The main objective is to describe the complication profile of the surgical procedure in these two patient populations.

Each patient will be followed during 12 months after the end of complete treatment (surgery ± adjuvant treatment).

A complementary study (observational study) of 250 patients will also be conducted to evaluate the acceptability of the technique (reconstruction by external pudendal flap) by the patients and to describe the factors associated with this acceptability.

Arms and Interventions

Arm Intervention/Treatment
Experimental: Patient with an ORL Cancer

Procedure: Oropharyngeal or oral cavity reconstruction
Oropharyngeal or oral cavity reconstruction will be performed using a free super thin external pudendal artery flap (STEPA flap). Post-operative follow-up and adjuvant treatment: Post-operative follow-up of patients will be performed according to the standards of the participating centers.

Outcome Measures

Primary Outcome Measures

  1. The occurrence of a limiting complication. Limiting complications are defined as total flap necrosis (flap failure) or donor site infection (Fournier Gangrene) within 4 weeks of the experimental procedure. [4 weeks for each patient]

Secondary Outcome Measures

  1. The postoperative complications will be evaluated according to the NCI-CTCAE version n°5 [12 months for each patient]

  2. The pain will be assessed according to a Likert scale between 0 (no pain) and 10 (worst pain). [12 months for each patient]

  3. The functional capacity of swallowing will be assessed via the Performance Status Scale for patients treated for an ORL cancer. It is composed of 3 scales: normal eating, public eating, voice intelligibility. [12 months for each patient]

  4. 4. The aesthetic evaluation will be performed according to a Likert scale. [12 months for each patient]
