All of the following are poor prognostic markers of multiple myeloma, except:: (A) t(1;14), (B) t(14;16), (C) 1q gain, (D) t(14;20)
Answer is A. Several cytogenetic abnormalities such as t(4;14), del(17/17p), t(14;16), t(14;20), nonhyperdiploidy, and gain(1q) are identified that confer poor prognosis in cases of multiple myeloma.
