Open Non-randomized Study on the Management of Operable T1-N0 or T2-N0 Oral Cavity and Oropharynx Cancer and Sentinel Lymph Node in Outpatient Surgery

Обзор

This is a single-center pilot study of open-label, non-randomized interventional research based on the outpatient management of 30 patients with T1-N0 or T2-N0 cancer in the oral cavity or oropharynx.

Подробное описание

Currently, patients with oral cancer or oropharynx T1-N0 or T2-N0 are treated by surgery on the tumor and the neck, both validated techniques are either with a systematic lymph node dissection or a search for lymph sentinel node (GS). The goal on the lymph sentinel nodes is to diagnose the presence of metastasis (s). With the GS technique, the length of hospital stay can be shorter. The limited invasiveness of tumor surgery of the oral cavity and oropharynx and GS and short postoperative monitoring is compatible with outpatient management, so it should be evaluated through a study clinical.

The main objective of this study is to evaluate the rate of conversion to complete hospitalization or re-hospitalization within 10 days of surgery J0. The secondary objectives are the evaluation of the acceptance rate of outpatient surgery by the eligible patient, complications related to outpatient management, the quality of life of the patient and the cost of the strategy over the first month following J0.

The surgical procedure associated with the sentinel lymph node technique is carried out in two stages:

\- Lymphoscintigraphy at Day-1 : This is the identification of the lymphatic network of the patient by a prior injection of radioactive tracer, nanocolloids labeled with technetium99, around the primary tumor. A planar or 3-minute CT image acquisition is performed 30 to 60 minutes after injection in anteroposterior and lateral view to identify the sentinel lymph nodes (GS(s)) which are then marked on the skin with an indelible marker. This routine care examination is done in an external act.

\- Surgery on D0: The patient is admitted to the hospital at 7:00 am in outpatient unit. He is reviewed by the anesthetist before the intervention and is transferred to the operating room for the intervention under General anesthesia.

The main tumor is operated by mouth. The ganglionic surgical procedure consists of the removal of the GS(s) by a limited cervical approach, following a cervical dissection line. The GS(s) are identified by a gamma detection probe, equipped with a high-resolution collimator whose tip is covered with a sterile disposable sleeve. Exeresis of the GS(s) is performed by removing the peri-ganglionic cellular tissue and avoiding any capsular intrusion. The GS lymph node (s) so taken is sent freshly by special request to the pathologist for final analysis according to the recommended procedure for GS.

The cervical dissection will be performed later if the definitive analysis finds a ganglionic invasion. In this case, the patient will be re-hospitalized in unit full hospitalization for cervical lymph node dissection: the ganglionic areas systematically concerned are the levels I, II, III and IV for tumors of the oral cavity and II, III and IV for the oropharynx. The gesture will be bilateral if the lymphoscintigraphy had found a bilateral drains. The cervical dissection parts are labeled and sent for routine final pathological analysis.
