About Mantle Cell Lymphoma
Mantle Cell Lymphoma (MCL) is a type of B-cell non-Hodgkin lymphoma with distinct pathophysiologic causes and risk factors. Here's what we know:
Pathophysiologic causes of MCL:
- MCL is characterized by a specific genetic abnormality called the t(11;14)(q13;q32) translocation, which leads to the overexpression of Cyclin D1 (CCND1) protein.
- This genetic alteration plays a crucial role in the development and progression of MCL.
- MCL is also associated with other recurrent genetic alterations that affect various cellular pathways.
Non-modifiable risk factors of MCL:
- Age: MCL is more commonly diagnosed in individuals aged 60 to 70 years.
- Sex Assigned at Birth: It is slightly more common in males than females.
Modifiable risk factors of MCL:
- There are no specific modifiable risk factors that have been identified for MCL. However, it's important to maintain a healthy lifestyle and minimize exposure to potential carcinogens.
It's worth noting that while these factors may increase the risk of developing MCL, they do not guarantee its development. MCL is a relatively rare cancer. If you have concerns about your risk for MCL, it's best to consult with a healthcare professional who can provide personalized advice based on your individual situation.
Early symptoms of MCL may be non-specific and people do not recognize them as symptoms of MCL. As a result, many cases of MCL are not diagnosed until MCL has spread in the body.
Symptoms of MCL include:
- Swollen lymph nodes, often in the neck and throat region
- Fatigue and lack of energy
- Unexplained weight loss
- Nonspecific symptoms such as appetite loss, nausea, and bloating
As MCL progresses or reaches a higher severity, additional symptoms may occur, including:
- B symptoms such as fever, drenching night sweats, and unintentional weight loss
- Abdominal pain and distended abdomen (enlarged liver or enlarged spleen)
- Increase in infections
- Headaches and easy bruising
It's important to note that not everyone with MCL will experience all of these symptoms, and some individuals may not have any symptoms in the early stages of the disease. If you are experiencing any concerning symptoms or have any questions, it's best to consult with your healthcare professional for an accurate diagnosis and appropriate management.
To diagnose MCL, in addition to obtaining a medical history and performing a physical examination, doctors may perform the following examinations, tests, and procedures:
- Blood test: A blood draw may be done to check:
- Complete blood count: This test includes measurement of the number of red blood cells, white blood cells, and platelets. It also helps look for signs of anemia or white blood cell abnormalities
- Lactate dehydrogenase (LDH): This test checks for signs of tissue damage
- Metabolic panel: This test measures electrolytes and the health of the liver and kidney.
- Biopsy: A small sample of tissue from the lymph node or tumor is taken and examined under a microscope to confirm the presence of MCL.
- Bone marrow aspiration and biopsy: A sample of bone marrow is taken and examined under a microscope for MCL.
- Body scans: Imaging tests like computed axial tomography (CAT) and positron emission tomography (PET) scans may be performed to determine the location and extent of the cancer in the body.
- Depending on symptoms and spread of MCL, additional procedures may include endoscopy of the upper gastrointestinal tract or colon to check for signs of MCL.
After diagnosing MCL, the healthcare team will assess the stage of MCL. Staging is based upon whether MCL has spread from the lymph node where the MCL first developed. Staging may be important for treatment recommendations.
Other examinations, test or procedures may be performed based on initial findings and individual factors. It's important to consult your healthcare provider for specific recommendations and guidance regarding these examinations, tests, and procedures.
The goals of treatment for MCL are to reduce symptoms, control the disease, improve quality of life, and achieve remission when possible.
In some cases when MCL hasn’t spread and isn’t causing symptoms, the doctor may recommend watchful waiting. This means they will monitor your overall health and watch for symptoms before starting treatment.
For treatment, here are the medication types, therapies, therapeutic procedures, health behavior changes, and other treatments that may be recommended for the treatment plan:
Medications:
- Chemotherapy: Traditional first-line treatment for MCL that uses drugs to kill cancer cells.
- Immunotherapy: Enhances the body's immune system to fight cancer cells. This may be used in combination with chemotherapy. An example of immunotherapy is CAR T-cell therapy.
- Targeted Therapy: Attacks specific molecules or pathways involved in cancer growth. An example of targeted therapy may be a monoclonal antibody. Targeted therapy may be used as part of maintenance therapy. Maintenance therapy is ongoing treatment after MCL is in remission to help prevent the cancer from recurring (comng back).
Therapeutic Procedures:
- Stem Cell Transplantation: Replaces damaged bone marrow with healthy stem cells after high-dose chemotherapy. It is important to note that stem cell transplantation does not cure MCL.
Health Behavior Changes:
- Maintain a healthy lifestyle with regular exercise, a balanced diet, and adequate rest.
- Follow recommended vaccination schedules to prevent infections.
It's important to consult with your healthcare professional for personalized advice on which treatment options are best suited for your individual situation. Medication dosing may be affected by many factors. Check with your health care professional about dosing for your individual situation. Side effects can occur. Check with your health care professional or read the information provided with your medication for additional side effect information.
