What is double hit lymphoma symptoms?

Is double hit lymphoma rare?

A rare, aggressive (fast-growing) type of B-cell non-Hodgkin lymphoma caused by changes in the DNA that affect a gene called the MYC gene and either the BCL2 gene or the BCL6 gene. Double-hit lymphoma may be hard to treat and has a poor prognosis.

Does double hit lymphoma come back?

Most people have advanced stage lymphoma when they are diagnosed. There is no standard treatment for double-hit or triple-hit lymphoma. These types of lymphoma can be difficult to treat. They have a higher risk of coming back (relapsing) than more common types of high-grade B-cell lymphoma.

Can you survive triple hit lymphoma?

Patients with triple hit lymphoma had a very poor prognosis, with an overall survival of 18 months, similar to the overall survival of patients with MYC/BCL6 double hit lymphoma (17 months) and those with MYC/BCL2 double hit lymphoma (20 months) (Fig.

Can you survive double expressor lymphoma?

Patients carrying the double expression of MYC and BCL2 (double expressor, DE) with or without concomitant translocations of MYC and BCL2, and/or BCL6 genes have a dismal prognosis. In patients affected by DE DLBCL without translocations, the 5-year overall survival (OS) is ~40% with R-CHOP.

What is double or triple hit lymphoma?

Double-hit or triple-hit B-cell lymphomas (DHL and THL) are rare subtype lymphomas usually associated with poor prognosis. It is defined by two or three recurrent chromosome translocations; MYC/8q24 loci, usually in combination with the t (14; 18) (q32; q21) bcl-2 gene or/and BCL6/3q27 chromosomal translocation.
