Abstract

Background

Cetuximab is crucial in the management of squamous cell carcinoma of the head and neck (SCCHN) patients. Grade 3-4 infusion reactions (IRs) occur in 2% of colorectal cancer (ASPECCT study, ∼1000 pts). Despite the 2.7% IR rate in the EXTREME trial (NEJM 2008), higher rates were reported in small series of SCCHN (6-10%). There is an urgent need to better appraise the natural history and the predictive factors for IRs in HNSCC pts exposed to Cetuximab.

Methods

The medical records from all consecutive SCCHN patients (n = 451) treated by cetuximab at Gustave Roussy (Cancer Campus Grand Paris) from January 2013 to December 2015 were reviewed. IR severity was defined as per the NCI-CTCAE v4.0. The impact of potential risk factors was analyzed (history of allergy, biological and clinicopathological variables).

Results

All patients analyzed received pre-medication including corticosteroids and antihistamines. Out of 441 patients, 34 patients (7.5%) presented grade 3-4 IR, nearly all of them requiring intensive care unit referral. Most of the IRs occurred during the first cycle (range: 1-3). The occurrence of grade 3-4 IR was associated with prior allergy history (P 

Conclusions

In real life, grade 3-4 IR consecutive to cetuximab appears far more common (7.5%) than reported in prospective trials. This is the largest series of patients ever focusing on the risk of IR induced by cetuximab in SCCHN pts. History of prior allergy is a strong predictor of IR and could be used to better allocate treatment and supervise pts. Further prospective data are however required to confirm this.
