ICD-10: C83.398

Diffuse large B-cell lymphoma (DLBCL) is a type of non-Hodgkin lymphoma characterized by the rapid proliferation of large B-cells. The ICD-10 code C83.398 specifically refers to DLBCL that occurs in other extranodal and solid organ sites, which distinguishes it from other forms of DLBCL that may be more localized or involve lymph nodes.

Clinical Description

Definition and Characteristics

Diffuse large B-cell lymphoma is the most common subtype of non-Hodgkin lymphoma, accounting for approximately 30% of all cases. It is known for its aggressive nature and can arise in various locations throughout the body, including lymph nodes, extranodal sites, and solid organs. The term "extranodal" refers to lymphomas that occur outside of the lymphatic system, which can include organs such as the spleen, liver, and gastrointestinal tract.

Presentation

Patients with DLBCL may present with a variety of symptoms, which can include:
- Lymphadenopathy: Swelling of lymph nodes, which may be painless.
- B symptoms: These include fever, night sweats, and unexplained weight loss.
- Extranodal involvement: Symptoms may vary depending on the organ affected. For instance, if the gastrointestinal tract is involved, patients may experience abdominal pain or changes in bowel habits.

Diagnosis

Diagnosis of DLBCL typically involves:
- Histopathological examination: A biopsy of the affected tissue is essential for confirming the diagnosis. The tissue is examined microscopically to identify the presence of large B-cells.
- Immunophenotyping: This process helps to determine the specific type of lymphoma by analyzing the proteins expressed on the surface of the cells.
- Imaging studies: CT scans, PET scans, or MRIs may be used to assess the extent of the disease and to identify extranodal involvement.

Staging

The staging of DLBCL is crucial for determining the appropriate treatment plan. The Ann Arbor staging system is commonly used, which classifies the disease based on the number of affected lymph node regions and the presence of extranodal disease.

Treatment Options

Treatment for DLBCL typically involves a combination of therapies, including:
- Chemotherapy: The most common regimen is R-CHOP, which includes rituximab, cyclophosphamide, doxorubicin, vincristine, and prednisone.
- Radiation therapy: This may be used in localized cases or as a consolidation treatment after chemotherapy.
- Targeted therapies: Newer treatments, such as CAR T-cell therapy, may be considered for relapsed or refractory cases.

Prognosis

The prognosis for patients with DLBCL can vary widely based on several factors, including the stage of the disease at diagnosis, the patient's age, overall health, and response to treatment. The International Prognostic Index (IPI) is often used to predict outcomes based on clinical features.
