What you need to know
A clinical or radiological finding of enlarged lymph nodes may raise suspicion of lymphoma, but a diagnosis cannot be made without tissue biopsy
Refer patients with unexplained persistent (>6 weeks), progressive, or generalised lymphadenopathy to the team most appropriate to arrange biopsy as directed by local referral pathways.
The commonest high grade lymphoma is diffuse large B cell lymphoma—an aggressive malignancy that is curable in 60-70% of patients with combined immunochemotherapy
The commonest low grade (indolent) lymphoma is follicular lymphoma—generally considered incurable, it follows a relapsing-remitting course with treatment required intermittently
The relapsing and remitting nature of indolent lymphomas can present unique mental health challenges for patients and requires patient education and emotional support
Non-Hodgkin lymphoma are malignant disorders arising from cells of the immune system, and manifest predominantly as lymphadenopathy or solid tumours. The classification of non-Hodgkin lymphoma is complex and ever-evolving, with more than 50 different subtypes listed in the latest World Health Organization classification.1 For non-specialists, however, they can most usefully be categorised as low grade (indolent) or high grade (aggressive) lymphoma since this broad distinction determines the likely natural course and management of the disease. In this clinical update we discuss the principles of diagnosis and management that are of particular relevance to non-specialist physicians, who may encounter patients with non-Hodgkin lymphoma during their initial presentation, therapy, and follow-up.
Sources and selection criteria
We searched PubMed using the key words “non-Hodgkin lymphoma,” “diffuse large B cell lymphoma,” and “follicular lymphoma” to identify reviews and major studies published since 2000. This was supplemented by a review of management guidelines (listed in the “Further educational resources” box), by personal experience of the authors, and by feedback from patients.
