From the Guidelines
The diagnostic approach for suspected lymphoma begins with a thorough history and physical examination, focusing on symptoms like persistent lymphadenopathy, fever, night sweats, and weight loss, and definitive diagnosis requires excisional lymph node biopsy for histopathological examination, as fine needle aspiration is usually insufficient, as recommended by the Lugano classification 1.
Diagnostic Steps
The diagnostic steps for lymphoma include:
- A thorough history and physical examination to identify symptoms and signs of lymphoma
- Excisional lymph node biopsy for histopathological examination, which is the preferred method for diagnosis, although core-needle biopsy may suffice when not feasible 1
- Clinical evaluation, including careful history, relevant laboratory tests, and recording of disease-related symptoms
- Imaging studies, such as PET-CT, which is the standard for FDG-avid lymphomas, whereas CT is indicated for nonavid histologies 1
- Bone marrow biopsy, which is only needed for DLBCL if the PET is negative and identifying a discordant histology is important for patient management 1
Treatment Options
The treatment options for lymphoma depend on the type, stage, and patient factors, and may include:
- Chemotherapy, such as ABVD regimen for Hodgkin lymphoma, typically administered every 2 weeks for 2-6 cycles 1
- Immunotherapy, such as rituximab, which is used in combination with chemotherapy for follicular lymphoma 1
- Radiotherapy, which is the treatment of choice for limited stage I and II follicular lymphoma, with a curative potential 1
- Watchful waiting, which may be appropriate for indolent lymphomas, with regular monitoring and follow-up 1
- Stem cell transplantation, CAR T-cell therapy, or targeted agents, which may be considered for advanced cases or relapsed/refractory disease 1
Staging and Prognosis
The staging of lymphoma is based on the Ann Arbor system, with modifications, and the prognosis varies widely based on lymphoma subtype, stage, and response to initial therapy, as recommended by the NCCN guidelines 1. The Follicular Lymphoma-specific International Prognostic Index (FLIPI) is used for prognostic purposes, and regular follow-up and monitoring are essential to assess treatment response and detect potential complications or secondary malignancies 1.
The treatment of lymphoma should be individualized, taking into account the patient's overall health, age, and other factors, and should be based on the most recent and highest quality evidence, such as the NCCN guidelines 1.

From the Research
Diagnostic Steps for Lymphoma
- The diagnosis of lymphoma typically involves a combination of clinical presentations, laboratory studies, and imaging modalities 2
- Laboratory studies may include complete blood count and peripheral blood flow cytometry to help identify abnormal cells 2
- Lymph node sampling is also recommended to confirm the diagnosis and determine the type of lymphoma 2
- Imaging modalities such as CT scans or PET scans may be used to stage the disease and monitor for high-risk clinical syndromes 2
Treatment Options for Lymphoma
- The treatment of lymphoma depends on the type and stage of the disease, as well as the patient's age and overall health 3
- Common treatment options for lymphoma include chemotherapy, radiation therapy, and targeted therapy 3, 4
- For patients with diffuse large B-cell lymphoma, the standard treatment is R-CHOP (rituximab, cyclophosphamide, doxorubicin, vincristine, and prednisone) 4, 5
- For patients with mantle cell lymphoma, treatment options may include R-CHOP, bendamustine-based therapy, or novel targeted agents 3
- The use of circulating tumor cells, circulating tumor DNA, and circulating exosomes may also assist in diagnosis, prognosis, and therapeutic monitoring 6
Emerging Trends in Lymphoma Diagnosis and Treatment
- There is a trend towards minimally invasive diagnostics, which can make it challenging to obtain accurate histopathological assessments of disease 6
- Emerging fields such as liquid biopsies and circulating tumor DNA may help to address these challenges and improve patient outcomes 6
- Novel targeted agents and immunotherapies are also being developed to improve treatment options for patients with lymphoma 3, 6
