Summary of "PET/CT and PET/MRI in Head and Neck Cancer."

Positron emission tomography (PET) with F-fluordeoxyglucose (FDG) in combination with computed tomography (CT) is well established for the diagnostic work-up of patients with head and neck cancer. Possible applications include the detection of an occult primary tumor metastatic to cervical nodes, locoregional staging, assessment of treatment response to external beam irradiation (also in combination with chemotherapy), and surveillance for recurrence. The success of high-precision irradiation techniques such as intensity-modulated radiation therapy (IMRT) appears to be improved by delineating the tumor volume using PET/CT. Combined PET/Magnetic Resonance Imaging (MRI) offers advantages in staging with regard to increased anatomical details and radiation dose reduction but is inferior to PET/CT in the detection of pulmonary metastases and secondary tumors. As shown by a randomized trial in patients with advanced head and neck cancer, neck dissection can be omitted if FDG PET/CT is negative after radiochemotherapy and survival is not compromised. With this high level of evidence PET/CT in head and neck cancer currently found its way into the catalog of diagnostic procedures for patients in the statutory health insurances.

Medical and Biotech [MESH] Definitions

Soft tissue tumors or cancer arising from the mucosal surfaces of the LIP; oral cavity; PHARYNX; LARYNX; and cervical esophagus. Other sites included are the NOSE and PARANASAL SINUSES; SALIVARY GLANDS; THYROID GLAND and PARATHYROID GLANDS; and MELANOMA and non-melanoma skin cancers of the head and neck. (from Holland et al., Cancer Medicine, 4th ed, p1651)

Dissection in the neck to remove all disease tissues including cervical LYMPH NODES and to leave an adequate margin of normal tissue. This type of surgery is usually used in tumors or cervical metastases in the head and neck. The prototype of neck dissection is the radical neck dissection described by Crile in 1906.

A form of RHABDOMYOSARCOMA arising primarily in the head and neck, especially the orbit, of children below the age of 10. The cells are smaller than those of other rhabdomyosarcomas and are of two basic cell types: spindle cells and round cells. This cancer is highly sensitive to chemotherapy and has a high cure rate with multi-modality therapy. (From Holland et al., Cancer Medicine, 3d ed, p2188)

A symptom, not a disease, of a twisted neck. In most instances, the head is tipped toward one side and the chin rotated toward the other. The involuntary muscle contractions in the neck region of patients with torticollis can be due to congenital defects, trauma, inflammation, tumors, and neurological or other factors.

Large veins on either side of the root of the neck formed by the junction of the internal jugular and subclavian veins. They drain blood from the head, neck, and upper extremities, and unite to form the superior vena cava.
