LGLL Understanding
The DelveInsight's LGLL epidemiology report gives a thorough understanding of LGLL by including details such as disease definition, symptoms, causes, pathophysiology, and diagnosis. Large granular lymphocytic leukemia (LGLL), is a chronic blood disorder with an increased number of large granular lymphocytes (LGLs) in the peripheral blood that accumulate over time. LGLs are characterized by enlarged lymphocytes containing noticeable granules, which can be observed under microscopic examination. In normal conditions, LGLs comprise about 10 to 15 percent of peripheral blood mononuclear cells, but in LGLL, the cases are characterized by extremely high number of LGLs in blood; either by higher number of LGLs than normal, or by a higher percentage compared to other types of white blood cells. Although there are no well-established causes and risk factors of LGLL, it is often times associated with some mutations (like STAT3 and STAT5b), associated comorbidities, age and some common manifestations.
Symptoms of LGLL can range from fatigue and B symptoms (fever, night sweat, and weight loss), changes in blood cell counts like anemia, neutropenia and thrombocytopenia, which can also lead to recurrent infections in certain cases, to splenomegaly, hepatomegaly, and even lymphadenopathy. Although it should be noted that about 30% of the patients are asymptomatic at the time of diagnosis.

Diagnosis
Since the signs and symptoms of LGLL are not very distinctive, with them overlapping with many other diseases and the fact that almost a third of the diagnosed patients are observed to be asymptomatic at the time of diagnosis, making a definite diagnosis for LGLL quite a necessity.
A definite LGLL diagnosis requires evidence of a chronic expanded clonal T- or NK-cell LGL population associated with an appropriate clinical context. It is based on cytology, immunophenotype analysis, and evidence of monoclonality. LGLL can be diagnosed by conducting several tests, including a complete blood count (CBC), usually the first test to show the main sign of LGLL, high white blood cell count and low neutrophil count; flow cytometry with an LGL Panel, which can show the presence of LGLL type; T-cell receptor gene rearrangement (TCR) further tests for types of T-cell clones; bone marrow biopsy; splenectomy and spleen analysis

LGLL Epidemiology
The epidemiology section provides insights about the historical and current LGLL patient pool and forecasted trends for individual seven major countries. It helps to recognize the causes of current and forecasted trends by exploring numerous studies and views of key opinion leaders. This part of the report also provides the diagnosed patient pool and their trends along with assumptions undertaken.

Key Findings
The disease epidemiology covered in the report provides historical as well as forecasted LGLL epidemiology scenario in the 7MM covering the United States, EU5 countries (Germany, Spain, Italy, France, and the United Kingdom), and Japan from 2019 to 2032.
In the year 2021, the total diagnosed incidence cases of LGLL were about 3840 cases in the 7MM which are expected to grow during the study period, i.e., 2019-2032.

The disease epidemiology covered in the report provides historical as well as forecasted LGLL epidemiology [segmented as Total diagnosed incidence cases, Total type-specific cases of LGLL, Total mutation-specific cases of LGLL, Total age-specific cases of LGLL, Total clinical manifestations-specific cases of LGLL and Total treated cases of LGLL by line of therapies] in the 7MM covering the United States, EU5 countries (Germany, France, Italy, Spain, and the United Kingdom), and Japan from 2019 to 2032.

Country Wise- LGLL Epidemiology
The epidemiology segment also provides the LGLL epidemiology data and findings across the United States, EU5 (Germany, France, Italy, Spain, and the United Kingdom), and Japan.

KOL- Views
To keep up with the current LGLL patient pool and forecasted trend, we take KOLs and SMEs ' opinions working in the LGLL domain through primary research to fill the data gaps and validate our secondary research. Their opinion helps to understand and validate the patient pool and forecasted trend.
