Indolent non-Hodgkin’s lymphomas

Big picture

Indolent non-Hodgkin’s lymphomas (indolent NHLs) are slowly growing mature lymphoid malignancies, usually of B-cell origin, with a long natural history, frequent relapses, and often an initially asymptomatic presentation.

The exam logic is:

Slow lymphocyte proliferation
→ slowly progressive lymphadenopathy / splenomegaly / marrow involvement
→ often advanced stage at diagnosis
→ do not treat automatically
→ “watch and wait” if asymptomatic and low tumor burden
→ treat when symptomatic, bulky, progressive, cytopenic, or organ-threatening

The key contrast is:

The hematology textbook emphasizes that indolent lymphomas have slow cell proliferation, may not need immediate therapy, are treated when progression or symptoms appear, and current therapies usually achieve remission but not definitive cure in advanced disease.
