QUESTION
Fibrosarcoma is a type of tumour which has?
OPTIONS
(A) TR = 1
(B) TR = -1
(C) Both of the above
(D) None of the above
ANSWER
(A) TR = 1
EXPLANATION
Fibrosarcoma is a malignant connective-tissue tumor characterized by invasive growth and, in this question's terminology, a tumor ratio (TR) of 1. A TR of -1 does not represent the characteristic value assigned here, so option A is the keyed answer and option B is incorrect; consequently, option C and D are also incorrect.
