Home> Non-Hodgkin’s lymphoma> Overview and Types

Non-hodgkin’s lymphoma, or non-Hodgkin’s cancer, is a type of blood malignancy that can occur at any age. It arises from lymph nodes present throughout the body. Based on the cell type that it originates from, there are various types of non-Hodgkin’s lymphoma, each with unique characteristic features. Early detection and timely treatment are extremely important for the effective management of this condition.

What is Non-Hodgkin’s Lymphoma?

Non-Hodgkin's lymphoma (NHL) is a type of cancer that originates in the lymphatic system, a key component of the body's immune system. When it comes to understanding non-Hodgkin's lymphoma meaning, it refers to the abnormal growth of lymphocytes, a type of white blood cell, leading to the formation of tumors in lymph nodes or other lymphatic tissues. Non-Hodgkin's cancer encompasses various subtypes, each with distinct characteristics and behaviors.

Unlike Hodgkin's lymphoma, non-Hodgkin's lymphoma can occur at any age and may involve lymph nodes throughout the body. Treatment strategies range from chemotherapy and radiation to immunotherapy, tailored based on the specific subtype and stage of the disease.

What are the Most Common Types of Non-Hodgkin’s Lymphoma?

There are various types of non-Hodgkin’s cancer based on the cell type that it originates from. The following are the different types of non-Hodgkin’s lymphoma:

Aggressive B-cell Lymphomas

Aggressive non-Hodgkin’s B-cell lymphomas are fast-growing and their effective management demands an aggressive treatment course. The following are the different types of aggressive B-cell lymphomas:

Diffuse Large B-cell Lymphoma (DLBCL)

DLBCL is a high-grade, aggressive B-cell lymphoma characterized by rapidly growing tumors. It commonly presents as enlarged lymph nodes and can affect various organs. Prompt diagnosis and intensive treatment, often involving chemotherapy, are crucial for managing DLBCL.

Mantle Cell Lymphoma

Mantle cell lymphoma is a subtype of B-cell lymphoma known for its involvement in the mantle zone of lymph nodes. It is often diagnosed at an advanced stage and tends to have an aggressive clinical course. Treatment may include chemotherapy, immunotherapy, and stem cell transplantation.

Lymphoblastic Lymphoma

Commonly seen in younger individuals, lymphoblastic lymphoma is an aggressive subtype characterized by the rapid proliferation of immature lymphocytes. It often presents as a mediastinal mass and can involve the bone marrow. Treatment involves intensive chemotherapy, and the prognosis varies based on factors like age and disease stage.

Burkitt Lymphoma

Burkitt lymphoma is a highly aggressive B-cell lymphoma. It is often associated with an Epstein-Barr virus infection. It commonly involves the jaw, central nervous system, and abdominal organs. Rapid treatment with high-dose chemotherapy is essential for favorable outcomes in Burkitt lymphoma.

Lymphoblastic Lymphoma

Commonly seen in younger individuals, lymphoblastic lymphoma is an aggressive subtype characterized by the rapid proliferation of immature lymphocytes. It often presents as a mediastinal mass and can involve the bone marrow. Treatment involves intensive chemotherapy, and the prognosis varies based on factors like age and disease stage.

Aggressive T-cell and NK Lymphomas

Aggressive T-cell and NK lymphomas have a faster growth rate and, therefore, demand a complex and comprehensive treatment regimen.

Peripheral T-cell Lymphoma (PTCL)

PTCL is an aggressive T-cell lymphoma arising from mature T-cells. It exhibits diverse clinical features and can involve the lymph nodes, skin, and internal organs. Treatment approaches include chemotherapy, targeted therapies, and stem cell transplantation, but outcomes can be challenging.

Angioimmunoblastic T-cell Lymphoma (AITL)

AITL is a rare and aggressive T-cell lymphoma affecting older adults. It is characterized by systemic symptoms, enlarged lymph nodes, and a unique histopathological appearance. Treatment may involve chemotherapy and targeted therapies, but AITL has a variable clinical course.

Systemic Anaplastic Large Cell Lymphoma (ALCL)

ALCL is marked by large, abnormal lymphocytes and can involve the skin, lymph nodes, and organs. It has distinct genetic features and may be classified into ALK-positive and ALK-negative subtypes. Treatment strategies include chemotherapy and, in some cases, targeted therapies.

Hepatosplenic Gamma/Delta T-cell Lymphoma

This rare and aggressive T-cell lymphoma primarily involves the liver, spleen, and bone marrow. It is often associated with immunosuppression. Due to its rarity, optimal treatment approaches are still being explored, but they typically include chemotherapy and, in some cases, stem cell transplantation.

What Are The Most Common Types Of Indolent Non-Hodgkin’s Lymphomas?

Indolent B-cell Non-Hodgkin’s Lymphomas

Follicular Lymphoma

Follicular lymphoma is a slow-growing non-Hodgkin’s B-cell lymphoma characterized by the formation of follicle-like structures in lymph nodes. It typically presents with painless lymph node enlargement and may involve the bone marrow. Although considered indolent, it may require treatment, often involving immunotherapy or chemotherapy.

Small Lymphocytic Lymphoma (SLL)

Small lymphocytic lymphoma (SLL) is closely related to chronic lymphocytic leukemia (CLL) and is characterized by the accumulation of mature-looking but abnormal lymphocytes. It often involves the lymph nodes, spleen, and bone marrow. Treatment may be delayed until the disease progresses, and watchful waiting is a common approach.

Marginal Zone Lymphoma

Marginal zone lymphoma arises from B-cells in the marginal zone of lymphoid tissues. It includes three subtypes: nodal, extranodal, and splenic. This indolent lymphoma may affect various organs, such as the stomach, salivary glands, or spleen. Treatment options vary based on the subtype and extent of disease involvement.

Waldenstrom Macroglobulinemia

Waldenstrom macroglobulinemia is a rare lymphoplasmacytic lymphoma characterized by the overproduction of IgM antibodies. It primarily involves the bone marrow and may lead to symptoms like fatigue and bleeding disorders. Treatment options include targeted therapies, chemotherapy, and plasmapheresis to manage symptoms and slow disease progression.

Indolent T–cell/NK-cell lymphomas

Cutaneous T-Cell Lymphoma

Cutaneous T-cell lymphoma (CTCL) comprises a group of rare lymphomas affecting the skin, with mycosis fungoides and Sézary syndrome being the most common subtypes. CTCL often presents with skin rashes, itching, and plaques. Treatment includes skin-directed therapies, phototherapy, and in advanced cases, systemic therapies.

Non-Hodgkin’s lymphoma (NHL) Subtypes in Children

Burkitt Lymphoma

Burkitt lymphoma is an aggressive form of non-Hodgkin’s cancer characterized by rapidly growing tumors. Burkitt lymphoma is associated with the Epstein-Barr virus and is highly responsive to intensive chemotherapy regimens.

Diffuse Large B-cell Non-Hodgkin’s Lymphoma (DLBCL)

Diffuse large B-cell non-Hodgkin’s lymphoma is a high-grade, aggressive lymphoma that can occur in children. It is characterized by rapidly growing tumors, often presenting as enlarged lymph nodes. Treatment typically involves a combination of chemotherapy and may include immunotherapy or stem cell transplantation.

Primary Mediastinal B-cell Lymphoma

Primary mediastinal B-cell lymphoma is a subtype of DLBCL that predominantly arises in the mediastinum, often affecting young adults and adolescents. While less common in children, it can occur. This lymphoma typically presents with symptoms related to the mediastinal mass, such as cough and difficulty breathing. Treatment involves multi-agent chemotherapy, and the prognosis varies based on various factors, including the response to treatment.

What are the Stages of Non-Hodgkin’s Lymphoma?

Non-Hodgkin’s lymphoma stages are categorized based on the extent of the disease’s spread. The treatment approach and prognosis vary for each stage. The following are the different non-Hodgkin’s lymphoma stages:

Stage 1 Non-Hodgkin's Lymphoma

In stage 1, non-Hodgkin's lymphoma is confined to a single lymph node region or a single organ. It is considered an early stage, and the disease has not spread beyond this localized area. Treatment options often include radiation therapy or, in certain cases, surgery to remove the affected lymph node or organ. The prognosis is generally favorable at this stage, with high chances of successful treatment.

Stage 2 Non-Hodgkin's Lymphoma

In stage 2, the lymphoma involves two or more lymph node regions on the same side of the diaphragm or a single organ and its regional lymph nodes. While still considered an early stage, the disease has progressed beyond a single localized area. Treatment approaches may include a combination of chemotherapy and radiation therapy, depending on the specific characteristics of the lymphoma.

Stage 3 Non-Hodgkin's Lymphoma

At stage 3, the lymphoma has spread to lymph node regions on both sides of the diaphragm. It may also involve nearby organs or tissues. This stage signifies more extensive disease involvement. Treatment typically involves systemic therapies like chemotherapy, and in some cases, radiation therapy may be included.

Stage 4 Non-Hodgkin's Lymphoma

In stage 4, the disease has advanced significantly, indicating widespread involvement of lymph nodes, multiple organs, or distant tissues. Non-Hodgkin's cancer at this stage may also affect the bone marrow and other extranodal sites. Treatment usually involves systemic therapies like chemotherapy and immunotherapy. The goal is often to manage symptoms, slow disease progression, and improve overall quality of life.

Conclusion

Non-Hodgkin's lymphoma is a serious form of cancer affecting the lymphatic system, with various subtypes and stages that impact treatment options and prognosis. Early detection and a tailored treatment approach play pivotal roles in improving outcomes for individuals facing this diagnosis. Ongoing research and advancements in cancer therapies offer hope for enhanced treatment strategies and better long-term survival rates.
