Background: This study was performed to investigate any association between cellular cholesterol homeostasis and chronic lymphocytic leukemia (CLL). CLL is characterized primarily by an abnormal accumulation of neoplastic B cells in the blood, bone marrow, lymph nodes and spleen. Methods: Men aged >50 years participated in this study. Enzyme-based plasma lipid profile estimations, peripheral bl...

Richter's transformation (RT) represents the development of high grade lymphoma, most commonly diffuse large B-cell lymphoma, in patients with chronic lymphocytic leukemia or small lymphocytic lymphoma (CLL/SLL). CLL/SLL may convert also to Hodgkin's lymphoma, the so-called Hodgkin's variant of Richter transformation. Histopathological proof is needed to confirm a definitive diagnosis. Patients...

The US Food and Drug Administration (FDA) on Wednesday granted accelerated approval for the expanded use of ibrutinib, marketed as Imbruvica, for chronic lymphocytic leukemia (CLL) patients who have previously received at least one therapy. This approval was based on a phase 1b-2 open-label, multicenter study that was designed to determine the safety, efficacy, pharmacokinetics, and pharmacodyn...

Chronic lymphocytic leukemia (CLL) and chronic myeloid leukemia (CML) are the most common leukemias of the elderly. However, the sequential occurrence of CML followed by CLL in the same patient is extremely rare. In the present report, a 71-yr-old man was diagnosed with Philadelphia (Ph) chromosome positive CML and treated with imatinib mesylate. He went into morphologic, cytogenetic, and molec...

Chronic lymphocytic leukemia (CLL) is characterized by the accumulation of mature-appearing lymphocytes in blood, bone marrow, lymph nodes, and spleen with a median lymphocyte count of 20-30 × 10(9)/L at the time of diagnosis. In half of the patients, the lymphocyte count doubles over a period of 1-year and cyclic rise up to 50 × 10(9)/L can occur in untreated patients while in others the count...

TP53 is one of the most important prognostic factors in chronic lymphocytic leukemia (CLL). Modulation of microRNAs by TP53 in CLL pathogenesis has been a hotspot. Besides, it has an intimate association with other cytogenetics and plays an important part in drug resistance of CLL. All above indicate an embedded TP53-centered network in CLL pathogenesis and prognosis. In this review, we focus o...

Chylothorax is characterized by accumalation of milky fluid called chyle into the plural space. Most common causes of cyhlothorax are trauma or surgery of thoracic duct and malignancies. Among the malignancies lymphoma is responsible approximately 70% of cyhlothorax but other lymphocytic tumors including chronic lymphocytic leukemia (CLL) is rarely reported. A 71 years old man with known CLL, p...

conclusions it was demonstrated that the presence of del6q21 in b-cll patients indicates poor prognosis and on the contrary, presence of del17p13 points at the good prognostic value of the disease. results deletion of 17p13 was found in 11 (16.6%) and deletion 6q21 was present in 5 (7.5%). statistical analyses were performed to investigate the correlation of these molecular-cytogenetic findings...

We investigated the rearrangement patterns of the gene coding for the beta chain of the T cell receptor (T, ) in 11 patients with T-cell derived chronic lymphoproliferative disorders, including T-cell prolymphocytic leukemia (TP11) and T-cell chronic lymphocytic leukemia (T-CLL). We found that all five cases of T-PLL. and five of six cases of T-CLL, displayed T4-gene rearrangements. clearly est...

Leukemic involvement of the breast is rare, particularly involvement by chronic lymphocytic leukemia (CLL). While concurrent invasive ductal carcinoma and CLL manifesting as a collision tumor in the breast is extremely rare, this association (CLL and carcinoma) has been described in other organs. We report here a case of a 58-year-old woman with concurrent invasive ductal carcinoma and CLL and ...
