Does This Genetic Variance Matter in DLBCL Survival?

Clin Lymphoma Myeloma Leuk; ePub 2016 Aug 21; Haws, et al

There were no substantial differences in survival between people with diffuse large B-cell lymphoma with MYC increased copy number (ICN) and those with no MYC in a study involving 76 individuals.

Investigators compared overall survival in participants with MYC ICN (n=33) to MYC negative patients (n=43), looking at the significance of increased MYC gene copy number. Among the results:

• There were no significant differences in survival.

• There was also no difference in survival between those with IHC MYC ≥40% vs IHC MYC<40%.

• Those with MYC ICN showed a slightly increased MYC protein expression.

• There appeared to be better overall survival in patients with Ki-67 >80%, but the difference was not statistically significant.

• Most patients in both groups—8 in every 10—were treated with rituximab based therapies.
