Is Hairy Cell Leukemia a Chronic Lymphocytic Leukemia (CLL)?
Chronic lymphoid cancer of the blood ( CLL ) is an oncohematological entity admit in the chronic lymphoproliferative syndrome characterized by an increase in a dysfunctional lymphoid population ; it is the most common cancer of the blood in western land . On the other hand , hairy cell leucaemia is a dissimilar pathology ; however , both share certain characteristic in coarse . So , hairy mobile phone leukemia is not a inveterate lymphocytic leukemia .
Chronic lymphocytic leukemia is a type of inveterate lymphoproliferative syndrome with leukemic expression .
CLL is a Cancer the Crab of the blood in which the bone marrow and organs of the lymphatic system of rules produce too many B lymphocytes , a character of livid blood cell . Under normal conditions , B and T lymphocytes are creditworthy for fighting infections , either by make antibody that attack the harmful elements that encroach upon or occur in our body ( bacillus lymphocytes ) , or attacking them straight ( thyroxin lymph cell ) .
In CLL , B lymphocytes progressively infiltrate thebone marrow , lymphatic tissue ( lymph and irascibility mainly ) and other organs such as the liver . The clinical manifestations of the disease are a issue of this infiltration that displaces the normal element of the parentage and keep the right functioning of the affect reed organ . to boot , the develop lymphocytes do not function correctly and can not fulfil their commission of defence of the organic structure .
Usually , CLL bear on mass over 60 years of age ( median eld is 70 year , only 20 % are under 65 ) , being extremely exceptional in children , and progresses very slowly . In many cases , people endure from this disease have no symptoms for age . It is only leukemia in which a higher incidence among crime syndicate members has been described ( 5 % ) .
Symptoms and Diagnosis of CLL
In more than 80 % of the patients , the CLL is diagnosed by a routine analysis or by chance , since they are normally completely asymptomatic .
In the persist character , the chief symptoms can be astheny ( impuissance , lack of energy and strength ) , lymphadenopathy ( exaggerated lymph nodes ) and repeated contagion . It is not unknown that there issplenomegaly(inflammation of the spleen ) orhepatomegaly(enlargement of the liver ) that can cause abdominal discomfort . Unlike what happens in lymphomas , fever , nighttime sweatsandweight lossare not frequent ( 10 % ) .
To plant the diagnosing of CLL , the morphological and immunophenotypic report of the line of descent is sufficient , although the sketch is unremarkably completed by prove the bone kernel , obtained by means of a puncture of the sternum or the ivory of the pelvis . For correct assessment , their cytogenetic and molecular characteristic must also be analyzed . It is also usual to consider which ganglion territories are involve by imaging techniques ( shadowgraph , ultrasound , scintigraphy , scan or magnetic resonance ) .
Treatment of Chronic Lymphocytic Leukemia
Patients with an early - level CLL commonly do not ask discussion for year and can lead a normal lifetime , except for the occasional dominance they are need to see if the disease progresses or stay stable . The criterion for start treatment are the presence of :
These patients should encounter treatment with one of the multiple chemotherapy regimens currently used , found mostly on a extremely effective broker send for fludarabine that is consort with other chemotherapeutic agents ( cyclophosphamide , mitoxantrone , Leukeran , bendamustine , etc . ) or a biotherapeutics federal agent such as rituximab .
Unlike other leukemias , CLL is not commonly treated with a transplant of hematopoietic progenitors due to the advanced age of most patients . However , young patients with aggressive CLL may benefit from this therapeutic mensuration if they have a histocompatible donor , as this is the only therapy that allow the disease to be cure . Currently , experts are starting to treat , with hopeful results , sure-enough patients who have a donor compatible with a new modality of haematopoietic transplanting , the so - call off reduced intensity transplant .
