Study Notes

Nonsurgical Management of Head and Neck Cancer

Over the last two decades, there has been a significant change in the management of head and neck cancer with the development of new surgical approaches and novel radiotherapy technologies and techniques.
Advances in chemotherapy drugs, chemoradiotherapy regimens, and biological agents have altered the morbidities from treatment and the short-term and long-term side effects.

Organ Preservation and Post-Treatment Function

There is a greater emphasis on organ preservation and post-treatment function in the management of head and neck cancer.
This has been achieved through the use of new radiotherapy techniques, such as intensity-modulated radiation therapy (IMRT), and the addition of chemotherapy to radiotherapy for advanced head and neck tumors.

Treatment Options

Chemoradiotherapy and surgery (with or without chemoradiotherapy) give approximately the same survival outcomes.
The decision-making process focuses on the long-term morbidities and survivorship issues.
The use of laser surgery and improved reconstructive options have made primary external beam radiotherapy (EBRT) and brachytherapy almost redundant for early tumors in the oral cavity.
The introduction of transoral robotic surgery (TORS) has made the head and neck oncology community reevaluate the treatment regimens, especially for oropharyngeal tumors.

Collaborative Team Approach

The management of orofacial cancers involves a collaborative team approach, including deciding on the optimal treatment regimen and transforming treatment delivery and support for the individual patient.

Radiotherapy and Chemoradiotherapy in Orofacial Cancer

Radiotherapy can be given as a primary treatment either alone or with chemotherapy when surgery is thought to be less appropriate as the primary treatment.
Radical radiotherapy is given with the intention of cure and is usually given to a relatively high dose and with a more protracted course.
Dose to organs at risk (OARs) may limit the total dose given, including the parotid and submandibular salivary glands, mandible, eyes, optic nerves, optic chiasm, spinal cord, and brainstem.

Adjuvant Radiotherapy

Adjuvant radiotherapy is given after surgery to destroy any residual microscopic disease remaining and improve the chance of local control.
Indications for adjuvant radiotherapy include close or positive margins at the primary tumor site, lymphovascular or perineural involvement, or if there has been tumor spillage at operation.
A large primary tumor (i.e., T3 or T4) would also be an indication for adjuvant radiotherapy.
