Ans. A, B & E
Papillary thyroid cancer or papillary thyroid carcinoma is the most common type of thyroid cancer, representing 75 percent to 85 percent of all thyroid cancer cases.
The Delphian (prelaryngeal/precricoid) node is one of the cervical lymph node groups that comprise level VI cervical lymph nodes.
Thyroid carcinomas may also involve this node.
PCT is generally a unencapsulated tumor.
Lymphatic spread is more common in PCT than hematogenous spread which is rare.
70 year survival rate of PCT is best among all thyroid carcinomas.
