Question 1

In classification of a tumor using the TNM system,the T refers to the:

Accepted Answer

The T in the TNM system refers to the size and extent of the primary tumor. The N refers to lymph node involvement and the M refers to the presence of distant metastasis. Histologic grading is not included in the TNM system.

Question 2

In the treatment of neoplastic disease,interferons and interleukins are associated with:

Accepted Answer

Interferons and interleukins are types of immunotherapy used in the treatment of neoplastic disease. They work by stimulating the body's own immune system to attack and destroy cancer cells.

Question 3

A histologic evaluation of a primary cancer that is graded as an "I" is considered well differentiated.

Accepted Answer

Primary cancers are graded on a scale of I to IV based on their degree of differentiation (how closely they resemble normal cells). Grade I cancers are considered well differentiated, meaning they closely resemble normal cells and are generally considered less aggressive than higher grade (less differentiated) cancers.

Question 4

A tumor consisting of differentiated cells has a higher probability for malignancy.

Accepted Answer

A tumor consisting of differentiated cells is less likely to be malignant because the cells are already specialized and have lower division rate compared to undifferentiated or poorly differentiated cells which have a higher probability of being malignant.
