Will my mother be unmutated if she has CLL?
If our mother CLL was a young cell when she went bad, she will be unmutated as will all her children. The cutoff for mutation status is 2%. Less than 2% is unmutated. More than 2% is mutated, the more mutated the better. Someone whose test shows they are 8% mutated is thought to have a better prognosis than someone 5% mutated.
Is venetoclax a good first treatment for unmutated CLL?
Put another way, people with unmutated CLL starting out on ibrutinib and venetoclax as a first treatment are doing just as well as those with mutated CLL. The old survival tables showing people]
What is the prognosis of unmutated IGHV CLL?
If one of the Y arms has gone under a mutation, we have mutated IGHV CLL that carries a favorable prognosis. If the Y arm is unmutated, our prognosis is less favorable (or maybe not, more on that later). 17p and 11q CLL are most often associated with unmutated IGHV.
What are the treatment options for chronic lymphocytic leukemia (CLL)?
[PUBMED Abstract] Because of its indolent nature, treatment for asymptomatic or minimally affected patients with chronic lymphocytic leukemia (CLL) with chemotherapy is not indicated, and observation is the generally accepted approach. [ 1]

In April 2020, the FDA approved a combination therapy of rituximab (Rituxan) and ibrutinib (Imbruvica) for adult patients with chronic CLL.
When does treatment for CLL start?
Patients with chronic lymphocytic leukemia (chronic lymphoid leukemia, CLL) do not need drug therapy until they become symptomatic or display evidence of rapid progression of disease, as characterized by the following: Weight loss of more than 10% over 6 months.
What would be the preferred first line therapy for patients with mutated TP53 or 17p deletion?
For higher-risk patients with 17p and 11q deletion or TP53 mutation, Jain and Brown agreed that novel agents are the preferred course of therapy.

What is first line treatment for CLL?
Chemoimmunotherapy (CIT) has been the standard first-line therapy for CLL. Age and comorbidities can help decide which patients may benefit from a CIT approach. FCR (fludarabine, cyclophosphamide, and rituximab) is the current standard treatment option for younger patients with CLL.
What percentage of CLL patients need treatment?
Around 30-50% of people diagnosed with CLL never require any treatment for their disease and can survive for many years despite their diagnosis.
Do you need treatment for CLL?
Chemotherapy is the main treatment if it's more advanced. Treatment can often help keep CLL under control for many years. It may go away after treatment initially (known as remission), but will usually come back (relapse) a few months or years later and may need to be treated again.
What is the most common treatment for patients who relapse with CLL?
The first-line chemo- immunotherapy regimen of FCR (combination of fludarabine, cyclophosphamide and rituximab) is most frequently used in patients with CLL, as long as they are fit and well with little or no other health problems.
What do we do with chronic lymphocytic leukemia with 17p deletion?
Allogeneic stem-cell transplantation (alloSCT) remains the recommended strategy for patients with deletion 17p who achieve a CR. Because most patients with CLL are older than 60 years at the time of diagnosis, reduced-intensity conditioning regimens are typically employed.
What is 17p deletion in CLL?
In chronic lymphocytic leukemia (CLL), deletion (del) of the short arm of chromosome 17 (17p13) is found in 5 to 8% of patients requiring first-line treatment and is associated with rapid disease progression as well as a poor response to treatment with a median overall survival (OS) of 2 to 3 years from the time of ...
Which therapy is contraindicated in chronic lymphocytic leukemia CLL patients with 17p deletion or TP53 mutated disease?
However, because of more adverse safety profiles, idelalisib combination therapies are not recommended in first-line treatment of 17p-deleted CLL if other treatment options are available.
What is the immunomodulating agent for CLL?
Immunomodulating agent: Lenalidomide stimulates T cells to kill leukemia cells. It may be used alone or with rituximab in patients with symptomatic or progressive, recurrent, or refractory CLL.
What happens after chronic lymphocytic leukemia?
After chronic lymphocytic leukemia has been diagnosed, tests are done to find out whether the cancer has spread.
What is stage 1 leukemia?
In stage I chronic lymphocytic leukemia , there are too many lymphocytes in the blood and the lymph nodes are larger than normal.
What is the name of the cancer in which the bone marrow makes too many lymphocytes?
Chronic lymphocytic leukemia is a type of cancer in which the bone marrow makes too many lymphocytes (a type of white blood cell). Chronic lymphocytic leukemia (also called CLL) is a cancer of the blood and bone marrow that usually gets worse slowly. CLL is one of the most common types of leukemia in adults.
What is PDQ cancer?
This PDQ cancer information summary has current information about the treatment of chronic lymphocytic leukemia. It is meant to inform and help patients, families, and caregivers. It does not give formal guidelines or recommendations for making decisions about health care.
What is BCL2 inhibitor therapy?
BCL2 inhibitor therapy: This treatment blocks a protein called BCL2 which is found on some leukemia cells. This may kill leukemia cells and make them more sensitive to other anticancer drugs. Venetoclax is a type of BCL2 therapy used to treat symptomatic or progressive, recurrent, or refractory CLL.
Where does CLL spread?
In chronic lymphocytic leukemia ( CLL ), the leukemia cells may spread from the blood and bone marrow to other parts of the body, such as the lymph nodes, liver, and spleen. It is important to know whether the leukemia cells have spread in order to plan the best treatment.
How is CLL treated?
Treatment of CLL ranges from observation with treatment of infectious, hemorrhagic, or immunologic complications to a variety of therapeutic options administered as single agents or combination therapy. In asymptomatic patients, treatment may be deferred until the disease progresses and symptoms occur. [ 3] Because the rate of progression may vary from patient to patient, with long periods of stability and sometimes spontaneous regressions, frequent and careful observation is required to monitor the clinical course. [ 5] Although even asymptomatic patients with del (17p) on fluorescence in situ hybridization (FISH) analysis (or TP53 mutation) may be followed with watchful waiting, frequent monitoring may be required to avert rapid progression. A meta-analysis of randomized trials showed no survival benefit for immediate versus delayed therapy for patients with early-stage disease. [ 6 ] [ Level of evidence: 1iiA] For patients with progressing CLL, treatment will not be curative in most cases. Selected patients treated with allogeneic stem cell transplantation have achieved prolonged disease-free survival (DFS); sometimes exceeding 20 years. [ 7 - 11] Prolonged DFS was also noted in young patients (<60 years) with IgVH hypermutation who received the FCR regimen (fludarabine, cyclophosphamide, and rituximab). [ 12 - 14]
What are the complications of CLL?
Complications of pancytopenia, including hemorrhage and infection, represent a major cause of death in these patients. [ 3] Immunological aberrations, including Coombs-positive hemolytic anemia, immune thrombocytopenia, and depressed immunoglobulin levels may all complicate the management of CLL. [ 4]
What is CLL in anatomy?
Anatomy. CLL is a disorder of morphologically mature but immunologically less mature lymphocytes and is manifested by progressive accumulation of these cells in the blood, bone marrow, and lymphatic tissues. [ 2]

It is intended as a resource to inform and assist clinicians who care for cancer patients. It does not provide formal guidelines or recommendations for making health care decisions.
What blood tests are done for autoimmune hemolytic anemia?
With suspicion of autoimmune hemolytic anemia, testing for reticulocyte count, indirect bilirubin, serum haptoglobin, antiglobulin (direct Coombs), and cold agglutinin may be helpful.
How long does a BCL2 patient live?
In older trials with data collected from the 1970s through the 1990s, the median survival for all patients ranged from 8 to 12 years. [ 3, 4] However, with the introduction of the B-cell receptor inhibitors and targeting of BCL2, the median survival for all patients has not been reached with over 10 years of follow-up.
Is chemo indicated for lymphocytic leukemia?
Because of its indolent nature, treatment for asymptomatic or minimally affected patients with chronic lymphocytic leukemia (CLL) with chemotherapy is not indicated, and observation is the generally accepted approach. [ 1] Because the rate of progression may vary, with long periods of stability and sometimes spontaneous regressions, frequent and careful observation is required to monitor the clinical course. One nomogram to predict time-to-first treatment relies on the number of lymph node sites, size of cervical lymph nodes, lactate dehydrogenase level, the IgVH mutational status, and the presence of del (11q) or del (17p) established by fluorescence in situ hybridization analysis. [ 2] Spontaneous regression, manifested by a sustained reduction of the malignant clone without therapy, occurs in less than 5% of patients. These patients almost exclusively have hypermutation of IgVH . [ 3]
What is mutated in CLL?
Nope, what is mutated is a small part of a Y shaped antibody that is on the surface of our CLL cell. IGHV is a fancy acronym for immunoglobulin heavy chain region. Immunoglobulin is another word for antibody. Think of an antibody as a person doing the YMCA dance on a CLL cell, but someone throwing up four arms instead of two.
What is the cutoff for mutation status?
The cutoff for mutation status is 2%. Less than 2% is unmutated. More than 2% is mutated, the more mutated the better. Someone whose test shows they are 8% mutated is thought to have a better prognosis than someone 5% mutated. And it makes a difference what region of the heavy chain (the outer Y arm of your antibody) you are mutated. Those mutated at the V3-21 region have CLL that acts unmutated.
How do lymphocytes fight viruses?
Enter lymphocytes. Once your body becomes aware of a virus invader, your body sends out navy seal type lymphocytes to fight the virus. How so? Well, lymphocytes size up the virus and create a specific type of antibody, a protein that can bind to a virus and neutralize it. Remember we said these antibodies (immunoglobulins) look like a Y on the surface or our cells? Well the tips of the Y arms on antibody are specifically created to bind to a particular virus. A measles antibody wont bind to a flu virus. If you get the flu, your body needs to create an antibody specific to that flu strain. That is why viruses can run their course, even if untreated. When we have functional immune systems, after a few days our newly made antibodies overwhelm and neutralize the cells hijacked by the virus. Wild, isn’t it?
What is the name of the disease caused by a corrupted gene?
A corrupted gene or chromosome in a skin cell might cause skin cancer. The cells that are corrupted with CLL are lymphocyte cells, hence the name chronic lymphocytic leukemia.
Is mutated CLL better than mutated CLL?
Recently some scientists have come up with a much different theory why having mutated CLL is better, a theory so different its almost like saying that up to now scientists have been completely wrong about why mutated CLL is better, like finding out the earth is round, not flat.
Do CLL cells have a life span?
So now we go back to mutated and unmutated CLL. Cells have a life span, just like humans. An old cell is more mature than a new cell. The thought with mutated CLL is that as a lymphocyte cell matures, the Y arms of the antibody on its surface go through a change, a mutation, in a way such that mutated CLL cells have more cancer fighting ability. Since we have one CLL cell that is the mother of all our CLL cells, if the mother cell was more mature and had a mutated antibody on it when it went bad, so will all our CLL cells forever after. If our mother CLL was a young cell when she went bad, she will be unmutated as will all her children.
Does CLL impair immune system?
So in explaining mutated IGHV, as a side benefit we now know how CLL impairs our immune systems. Our cancerous lymphocytes do not work as they should and don’t make enough antibodies. And now you know something about the “Ig numbers on our labs. Ig is an abbreviation for immunoglobulins, immunoglobulins are another word for antibodies. Antibodies are proteins on the surface of our lymphocytes that attack invaders. If we have low Ig numbers on our labs, our bodies are not making enough antibodies to protect us from invaders like viruses, bacteria and even pollen.
