	'''Large-cell lymphoma''' is a type of [[non-Hodgkin lymphoma]] (NHL) characterized by large malignant [[lymphocyte]]s with prominent nuclei. It encompasses several subtypes, including [[Diffuse large B-cell lymphoma]] (DLBCL), the most common form of NHL in adults, and [[Primary mediastinal B-cell lymphoma]] (PMBCL), a subtype that typically arises in the [[thymus]]. Large-cell lymphomas are aggressive malignancies that require prompt diagnosis and treatment.

'''Large-cell lymphoma''' is a type of [[non-Hodgkin lymphoma]] (NHL) characterized by large malignant [[lymphocyte]]s with prominent nuclei. It encompasses several subtypes, including [[Diffuse large B-cell lymphoma]] (DLBCL), the most common form of NHL in adults, and [[Primary mediastinal B-cell lymphoma]] (PMBCL), a subtype that typically arises in the [[thymus]]. Large-cell lymphomas are aggressive malignancies that require prompt diagnosis and treatment.

==Etiology and Risk Factors==
The exact cause of large-cell lymphoma is not fully understood, but it is believed to involve a combination of genetic and environmental factors. Risk factors may include:
* Age, with a higher incidence in older adults
* Immune system deficiencies or disorders
* Exposure to certain chemicals or radiation
* A history of certain infections, such as [[Epstein-Barr virus]] (EBV) associated with DLBCL

==Pathophysiology==
Large-cell lymphomas originate from the transformation of either [[B-cell lymphocytes]] or [[T-cell lymphocytes]], leading to the uncontrolled proliferation of large, abnormal lymphocytes. These malignant cells can accumulate in lymphoid tissues, such as [[lymph nodes]], the [[spleen]], and the [[bone marrow]], and may spread to other organs, causing a wide range of symptoms.

==Clinical Features==
Symptoms of large-cell lymphoma can vary depending on the subtype and the organs involved but may include:
* Painless swelling of lymph nodes in the neck, armpits, or groin
* Unexplained weight loss
* Fever and night sweats
* Fatigue
* Difficulty breathing or chest pain (in cases where the mediastinum is involved)

==Diagnosis==
Diagnosis of large-cell lymphoma typically involves a combination of:
* Physical examination
* Laboratory tests, including complete blood count (CBC) and lactate dehydrogenase (LDH) levels
* Imaging studies, such as [[Computed tomography|CT scans]] or [[Positron emission tomography|PET scans]]
* Biopsy of affected tissue, which is essential for confirming the diagnosis and determining the specific subtype of lymphoma

==Treatment==
Treatment for large-cell lymphoma varies depending on the subtype, stage, and patient's overall health but may include:
* [[Chemotherapy]], often combined with the monoclonal antibody [[rituximab]] for B-cell lymphomas
* [[Radiation therapy]], particularly for localized disease
* Stem cell transplantation in cases of relapse or refractory disease
* Targeted therapy and immunotherapy for certain subtypes and situations

==Prognosis==
The prognosis for large-cell lymphoma depends on a variety of factors, including the subtype, stage at diagnosis, patient's age, and response to treatment. The International Prognostic Index (IPI) is commonly used to help predict outcomes. Despite being aggressive, many cases of large-cell lymphoma, especially DLBCL, can be cured with appropriate treatment.

==Prevention==
There are no specific measures to prevent large-cell lymphoma. However, maintaining a healthy immune system and avoiding known risk factors may reduce the risk.
