ESTS

• Complete blood count (CBC):Battery of screening tests that typically includes hemoglobin (Hgb), hematocrit (Hct), red blood cell (RBC) count and morphology, indices, and distribu- tion width index; platelet count and size; white blood cell (WBC) count and differential.

• Immunological surveys:Measure levels of T cells, natural killer (NK) cells, macrophages, and so on.

• Human papillomavirus (HPV; particularly for type 16) test: To screen for presence of HPV.

• Biochemical profile:Battery of tests including electrolytes, glucose, total protein, amylase, blood urea nitrogen

(BUN)/creatinine (Cr), bilirubin, total CO2, cholesterol, lipids,

and aspartate aminotransferase (AST)/alinine aminotransferase (ALT) to evaluate general status of organ function.

TUDIES

• Direct/indirect laryngoscopy:Provides direct visualization of structures of the mouth and throat by means of either a rigid or flexible endoscope. Allows for biopsy and aspiration of secretions for cytology.

• Laryngeal computed tomography (CT) scan:X-ray procedure that uses a computer to produce a detailed picture of a cross- section of the body.

• Magnetic resonance imaging (MRI) scan:Evaluates tumor status and treatment options.

• Positron emission tomography (PET) scan:Measures the activity or functional level of the brain by measuring its use of glucose.

• Single photon-emission tomography (SPECT) scan:Nuclear medicine procedure in which a gamma camera rotates around the client and takes pictures.

• Laryngography:X-ray examination of the larynx after the insertion of a contrast medium.

• Chest x-ray:Evaluates organs and structures within the chest. • Pulmonary function studies, including spirometry, lung

volumes, and perfusion:Measure how well the lungs take in and release air and how well they move oxygen into the blood.

• Arterial blood gases (ABGs)/pulse oximetry:Blood test or peripheral scan to measure oxygen content and saturation of the blood

May reveal anemia, which is a common problem. Folate defi- ciency is very common in clients with history of alcoholism and malnutrition.

May be done for clients receiving chemotherapy or immunother- apy to determine status of immune system and to assist with use of vaccines for manipulation of cancer-directed immune response therapy.

HPV-related cancers tend to occur on the tonsillar area and the base of the tongue and the oropharynx, whereas non–HPV-related tumors tend to involve the anterior tongue, floor of the mouth, and the mucosa that covers the inside of the cheeks and alveolar ridges where the teeth are located. Changes may occur in organ function as a result of cancer,

metastasis, and therapies.

Visualizes local or regional cancers of the oropharynx and upper airways and allows staging.

Defines tumor extension deep in the laryngeal mucosal surface, cartilaginous invasion, and metastatic disease to the lymph nodes of the neck. Has largely replaced contrast laryngography as the primary method for staging laryngeal carcinoma (Silverman et al, 1984).

MRI is most often used as the primary imaging modality when evaluating tumor spread in nasopharynx, oropharynx, palate, base of tongue, and floor of mouth.

Because cancer cells are dividing rapidly, they break down glucose much faster than do normal cells. The increased activity will show up on a PET scan and can indicate both primary and metastatic tumors. PET scan allows identification of tumor, especially in difficult cases where no obvious mass was seen clinically or on either CT or MRI (American Head and Neck Society, n.d.).

SPECT is particularly useful for detection of occult head and neck tumors and for assessing possibility of recurrence. It may also help stage primary tumors, differentiate metastatic from reactive lymph nodes in the neck, and screen for distant metastases (Olmos et al, 1997).

May be performed to study blood vessels and lymph nodes.

Done to establish baseline lung status and to identify metastases. Chronic obstructve pulmonary disease (COPD) is common in

this group of clients. Abnormal findings may indicate need for additional interventions to improve pulmonary reserve prior to surgery.

May be done to establish baseline and monitor status of lungs.
