Chronic lymphocytic leukemia (CLL), a malignant tumour, is characterized by expansion of mature monoclonal B lymphocytes expressing CD23 and CD5 in secondary lymphocytic organs, blood, and bone marrow. Here, we provide an in-depth review of CLL, emphasizing its pathophysiology, cytogenic changes, and treatment strategies, particularly the efficacy and challenges of treatments, such as Bruton tyrosine kinase (BTK) inhibitors, B cell lymphoma 2 (BCL2) inhibitors, and phosphatidylinositol 3-kinase (PI3K) inhibitors, as well as the need to understand their role in managing disease progression, chemoresistance, and intolerance. In addition, we explore efficacy based on patient response and comparison between monotherapy and combination therapy. We also highlight the need for innovative strategies to overcome treatment resistance and enhance patient outcomes.

The combination of the drug acetazolamide and sulforaphane is a good example of combination therapy to treat cancer. The cells in the interior of a large tumor often die due to the hypoxic and...
Cancer Therapies
However, cancer treatments can pose several challenges, as therapies used to kill cancer cells are generally also toxic to normal cells. Moreover, cancer cells mutate rapidly and can develop resistance to chemical agents or radiation therapy. Besides, all types of cancer cells may not respond to the same therapy. Some cancer cells respond to one...
