Head and Neck Cancer and Salivary Gland Tumors Flashcards
About 80% ofsalivary gland tumors occur in the parotid
glands
T
only about l % occur in the sublingual glands.
T
About 80% of parotid gland tumors are benign
T
50% of submandibular gland
tumors and 80% of minor salivary gland tumors are
malignant
T
Risk of3.4 for oral cavity and 6.8 for
oropharynx SCC in current tobacco smokers compared with nonsmokers
T
HPV-11, are associated with the development of malignancy in the
oropharynx as well as ofthe cervix and anogenital tract
F HPV-16, are associated with the development of malignancy in the
oropharynx as well as ofthe cervix and anogenital tract
Pleomorphic Adenoma are most common in the fourth to
fifth decade.
T
5% of pleomorphic adenomas
may undergo malignant transformation
F 15% of pleomorphic adenomas
may undergo malignant transformation
Warthin Tumor is the
second most common tumor of the parotid gland and is benign
T
Warthin tumors predominantly occur in males of 50 to 70 years of
age, most frequently smokers
T
are the most common unilateral
salivary gland tumors (5%-14%)
F is the most common bilateral
salivary gland tumors (5%-14%)
Warthin can diagnose by PET scan
F. Warthin tumors do not infrequently
demonstrate fluorodeoxyglucose uptake on PET scan, potentially
leading to a false-positive study
Mucoepidermoid Carcinoma is the most common salivary gland malignancy (about 35% of
salivary gland cancers
T
Low- and intermediate-grade tumors often present
as asymptomatic slow-growing, solitary masses
T
Overall survival is 80%
to 90% for low- and intermediate-grade tumors
