Role of FCγRIIIA and FCγRIIA Receptor Polymorphisms

Completed
Conditions
Upper Gingival Squamous Cell Carcinoma
Interventions
Other: Blood sample for identifying the polymorphism
Registration Number
NCT01827956
Lead Sponsor
Institut Bergonié
Brief Summary

Hypothesis:

Cetuximab, an anti-EGFR antibody, is used with radiotherapy in the treatment of locally advanced and inoperable upper aerodigestive tract cancers. Actually, no predictive biomarkers of Cetuximab antitumor activity are known in this setting. It has been shown recently that FCγRIIIA and FCγRIIA receptor polymorphisms played a role in antitumor activity of trastuzumab and cetuximab.

The investigators therefore hypothesized that FCγRIIIA and FCγRIIA receptor polymorphisms may play a predictive role in Cetuximab effectiveness in upper aerodigestive tract cancers with recurrence or metastatic disease that make them inaccessible to loco regional treatment.

Detailed Description

Hypothesis:

Cetuximab, an anti-EGFR antibody, is used with radiotherapy in the treatment of locally advanced and inoperable upper aerodigestive tract cancers. Actually, no predictive biomarkers of Cetuximab antitumor activity are known in this setting. It has been shown recently that FCγRIIIA and FCγRIIA receptor polymorphisms played a role in antitumor activity of trastuzumab and cetuximab.

We therefore hypothesized that FCγRIIIA and FCγRIIA receptor polymorphisms may play a predictive role in Cetuximab effectiveness in upper aerodigestive tract cancers with recurrence or metastatic disease that make them inaccessible to loco regional treatment.

This study is a multicentre prospective pharmacogenetic observational study, conducted on locally advanced and inoperable upper aerodigestive tract cancers.

Secondary Outcome Measures
NameTimeMethod
Progression-free survival Overall survival ToxicityProgression-free survival: Tumour evaluation will be done at baseline and at 4 months or until the earlier of the following events: disease progression, patient death.

Overall survival: defined as the time between the first cycle of chemotherapy and the date of death, all causes. In the absence of death confirmation, survival data are censored from the date of last news
