Most head and neck cancers are of the squamous cell variety and may be preceded by various precancerous lesions. Minor salivary gland tumors are not uncommon in these sites. Specimens removed from the lesions may show the carcinomas to be noninvasive, in which case the term carcinoma in situ is applied. An invasive carcinoma will be well differentiated, moderately well-differentiated, poorly differentiated or undifferentiated.
Tumor grading is recommended using Broder classification (Tumor Grade [G]):
This complementary and alternative medicine (CAM) information summary provides an overview of the use of Selected Vegetables/Sun's Soup as a treatment for people with cancer. The summary includes a brief history of Selected Vegetables/Sun's Soup and a review of animal and human studies. The information in the Human/Clinical Studies section is summarized in a table located at the end of that section.
This summary contains the following key information:
"Selected Vegetables" and "Sun's Soup"...
No statistically significant correlation between degree of differentiation and the biologic behavior of the cancer exists; however, vascular invasion is a negative prognostic factor.
Other tumors of glandular epithelium, odontogenic apparatus, lymphoid tissue, soft tissue, and bone and cartilage origin require special consideration and are not included in this section of PDQ. Reference to the World Health Organization nomenclature is recommended.
The term leukoplakia should be used only as a clinically descriptive term meaning that the observer sees a white patch that does not rub off, the significance of which depends on the histologic findings. Leukoplakia can range from hyperkeratosis to an actual early invasive carcinoma or may only represent a fungal infection, lichen planus, or other benign oral disease.
