Nonetheless, there is a well-outlined histological classification used by pathologists.194 Benign and malignant tumors of the salivary glands are divided into epi-thelial, nonepithelial, and metastatic neoplasms. Benign epithe-lial tumors are most commonly pleomorphic adenoma (85%), monomorphic adenoma, Warthin’s tumor (papillary cystad-enoma lymphomatosum), oncocytoma, or sebaceous neoplasm. Nonepithelial benign lesions include lipoma and hemangioma. Treatment of benign neoplasms is surgical excision for diag-nostic and therapeutic purposes. The parotid superficial lobe is usually dissected off of the facial nerve, which is preserved. For pleomorphic adenoma, an extracapsular dissection is favored over enucleation due to tumor pseudopods, incomplete excision, and a higher risk of tumor spillage, all of which are associated with higher recurrence rates.195 Recurrence is associated with a high degree of morbidity.Malignant epithelial tumors range in

Nonetheless, there is a well-outlined histological classification used by pathologists.194 Benign and malignant tumors of the salivary glands are divided into epi-thelial, nonepithelial, and metastatic neoplasms. Benign epithe-lial tumors are most commonly pleomorphic adenoma (85%), monomorphic adenoma, Warthin’s tumor (papillary cystad-enoma lymphomatosum), oncocytoma, or sebaceous neoplasm. Nonepithelial benign lesions include lipoma and hemangioma. Treatment of benign neoplasms is surgical excision for diag-nostic and therapeutic purposes. The parotid superficial lobe is usually dissected off of the facial nerve, which is preserved. For pleomorphic adenoma, an extracapsular dissection is favored over enucleation due to tumor pseudopods, incomplete excision, and a higher risk of tumor spillage, all of which are associated with higher recurrence rates.195 Recurrence is associated with a high degree of morbidity.Malignant epithelial tumors range in

and a higher risk of tumor spillage, all of which are associated with higher recurrence rates.195 Recurrence is associated with a high degree of morbidity.Malignant epithelial tumors range in aggressiveness based on tumor histology, grade, perineural invasion, and regional metastases. Mucoepidermoid carcinoma is the most common primary malignancy of the salivary glands and can be high grade (more epidermoid) or low grade (more mucinous). High grade mucoepidermoid carcinoma can be hard to differentiated from squamous cell carcinoma, particularly on FNA. Adenoid cystic is the second most common primary salivary gland malignancy and has three histological subtypes: tubular, cribriform, and solid. Higher grade/risk tumors have a higher degree of solid differentiation.194 Adenoid cystic cancers are known for peri-neural invasion and late recurrences and distant metastases.

cancers are known for peri-neural invasion and late recurrences and distant metastases. Car-cinoma ex pleomorphic adenoma is an aggressive malignancy that arises from a preexisting benign mixed tumor highlighting the importance of removing these benign masses before malig-nant transformation.Surgical excision remains the standard of care, typi-cally with facial nerve preservation unless the nerve is directly invaded by tumor. For tumors that extend beyond the superficial lobe, nerve branches can be splayed, and a total parotid can be performed by removing parotid tissue deep to the nerve while preserving the integrity and function of the nerve. Whenever possible, the nerve is preserved even if microscopic disease is left on the nerve, so long as gross tumor is not left behind (i.e., the nerve is not encased). If this is not possible or if the nerve is not working preoperatively, nerve sacrifice is usually recommended.Elective neck dissection is warranted in high-grade muco-epidermoid

On the other hand, when presented with a total glossectomy defect, where thick tissue is desired for adequate volume reconstruction, the rectus may be the optimal donor site.

care facilities and hospice care allow patients to retain dignity when they have a limited short-term outlook.Follow-Up CarePatients diagnosed and treated for a head and neck tumor require follow-up care aimed at monitoring for recurrence and the side effects of therapy. The NCCN guidelines recommend follow-up assessment every 3 months for the first year after treatment, every 4 months during the following year, and then every 6 months until year 4, with an annual follow-up at 5 years post treatment and thereafter.106 This regimen is not well followed in North America, and further investigation is required to assess why this might be and to improve adherence rates.210 Follow-up should consist of a thorough history to assess for any emerg-ing symptoms such as pain, otalgia, or dysphagia as these are often the first sign of a recurrence. Assessment by speech lan-guage pathology and a dietician is often beneficial to ascertain swallowing function and nutritional intake, respectively.

Some patients require dilation or reinsertion of a gastrostomy tube if they develop pharyngeal strictures and are unable to maintain their weight. The history should be followed with a thorough head and neck examination, including fiberoptic nasolaryg-noscopy, because of the significant risk of developing a sec-ond primary in the upper aerodigestive tract.93 Patients should have their thyroid stimulating hormone (TSH) checked once a year, especially in those that have radiation as they may develop hypothyroidism at an earlier age than the general population. Shoulder dysfunction after neck dissection with extensive accessory nerve dissection or in patients who have had a scapu-lar system free flap should be managed with physiotherapy to minimize the long-term effects and improve function.

Patients should be healthy enough to tolerate curative treat-ment, specifically surgery per guidelines, and screening should be discontinued once the patient has not smoked for 15 years or develops a life-limiting health condition, becomes unable to tolerate lung surgery, or is unwilling to undergo curative lung resection. With this approach, it is expected that 50% of diagnosed cancers will be early stage. Screening of patients age 50 years or older with a 20 pack-year or greater history and additional risk factors (as determined by the Tammemagi lung cancer risk calculator or other validated risk scores) that increase the risk of lung cancer to 1.3% or greater should also be considered as part of lung cancer screening programs.
