Erbitux in combination with Docetaxel and Cisplatin as induction therapy in patients treated for locally advanced head and neck cancer


Patients treated for locally advanced head and neck cancer may respond better to treatment with the addition of Cetuximab ( Erbitux ) to chemotherapy, according to a phase II study.

In the study, 39 patients with stages 3 or 4 head and neck cancer were treated initially with a combination of Docetaxel ( Taxotere ), Cisplatin ( Platinol ) and Cetuximab, after which they received radiation therapy and additional Cisplatin and Cetuximab.

Erbitux is often prescribed for metastatic colorectal cancer and is used in conjunction with radiation therapy to treat squamous cell carcinomas of the head and neck.
This is the first time it has been used in combination with Docetaxel and Cisplatin as induction therapy.

“ We found that adding cetuximab to standard chemotherapy helped head and neck cancer patients respond better to treatment. Out of 37 patients, 32 responded to induction treatment for an 86 percent response rate, and all patients had their tumors reduced, either partially or completely, after radiation was completed, ” said Ethan Argiris, lead investigator and at University of Pittsburgh Medical Center.

Further evaluation of this treatment has shown that the complete disappearance of the primary tumor occurred in about 80 percent of patients.
After two years the same percentage of patients remained cancer-free.

“ Given that the majority of our patients had stage 4 disease, our efficacy results are thus far very encouraging,” said Argiris.

“ While longer follow-up will be needed to assess long-term efficacy and side effects, the addition of Cetuximab to chemotherapy and radiotherapy is very promising and could become the standard of care in the next few years, ” said Argiris.
.
Head and neck cancers are a group of biologically similar cancers originating from the upper aerodigestive tract, including the lip, mouth, nasal cavity, paranasal sinuses, pharynx and larynx that affect more than 45,000 individuals in the U.S. each year.
Most head and neck cancers are classified as squamous cell carcinomas.
Head and neck cancers are strongly associated with environmental and lifestyle risk factors, including tobacco smoking, alcohol consumption and certain strains of the sexually transmitted human papilloma virus.
