The most common treatment protocol for DLBCL
Diffuse large B-cell lymphoma
Diffuse large B-cell lymphoma is a cancer of B cells, a type of white blood cell responsible for producing antibodies. It is the most common type of non-Hodgkin lymphoma among adults, with an annual incidence of 7–8 cases per 100,000 people per year in the USA and the UK. This cancer occurs primarily in older individuals, with a median age of diagnosis at approximately 70 years of age, though it …

What is the prognosis for large B cell lymphoma?
Prognosis of diffuse large B-cell lymphoma (DLBCL) Diffuse large B-cell lymphoma (DLBCL) is usually treated with the aim to cure. DLBCL usually responds well to immunochemotherapy, and many people will achieve a complete remission, with around 70 percent achieving this with standard first line treatment.

What is the first line treatment for DLBCL?
Background: The first-line treatment of diffuse large B-cell lymphoma (DLBCL) is the combination of rituximab with CHOP (cyclophosphamide, doxorubicin, vincristine, prednisone) chemotherapy, curing approximately 60% of patients.
How long is treatment for diffuse large B-cell lymphoma?
The most widely used treatment for DLBCL presently is the combination known as R-CHOP (rituximab [Rituxan], cyclophosphamide [Cytoxan], doxorubicin [Adriamycin], vincristine [Oncovin], and prednisone) The R-CHOP regimen is usually given in 21-day cycles (once every 21 days) for an average of 6 cycles.
How is B-cell lymphoma treated?
Chemotherapy is the main way to treat most types of B-cell lymphoma. You can get this on its own, or combine it with radiation or immunotherapy. Chemo uses drugs to kill fast-dividing cells in your body, including cancer cells. You get this medicine through a vein (IV), or you take it as a pill by mouth.
Is Stage 4 diffuse large B-cell lymphoma curable?
DLBCL is fatal if left untreated, but with timely and appropriate treatment, approximately two-thirds of all people can be cured. The following discussion will review the risk factors, classification, symptoms, treatment, and prognosis of this type of non-Hodgkin lymphoma.
How fast does DLBCL grow?
Symptoms. Symptoms can start or get worse in just a few weeks. The most common symptom is one or more painless swellings. These swellings can grow very quickly.
What type of lymphoma is not curable?
Lymphoplasmacytic lymphoma or Waldenstrom macroglobulinemia. It's found mainly in the bone marrow, lymph nodes, and spleen. This type of lymphoma can't be cured.
What is the best treatment for large B-cell lymphoma?
Diffuse large B-cell lymphoma Most often, the treatment is chemotherapy (chemo), usually with a regimen of 4 drugs known as CHOP (cyclophosphamide, doxorubicin, vincristine, and prednisone), plus the monoclonal antibody rituximab (Rituxan). This regimen, known as R-CHOP, is most often given in cycles 3 weeks apart.
What is the standard treatment for lymphoma?
Chemotherapy. Chemotherapy uses drugs to destroy fast-growing cells, such as cancer cells. The drugs are usually administered through a vein, but can also be taken as a pill, depending on the specific drugs you receive.
Can diffuse B-cell lymphoma be cured?
The infusional regimen has been shown to have a high cure rate in patients with Burkitt lymphoma81 and to be at least as effective as CHOP-R in patients with typical diffuse large B-cell lymphoma.
Can you live 20 years with lymphoma?
Most people with indolent non-Hodgkin lymphoma will live 20 years after diagnosis. Faster-growing cancers (aggressive lymphomas) have a worse prognosis. They fall into the overall five-year survival rate of 60%.
What is meant by 5-year survival rate?
ser-VY-vul ...) The percentage of people in a study or treatment group who are alive five years after they were diagnosed with or started treatment for a disease, such as cancer. The disease may or may not have come back.
What are the final stages of lymphoma?
Stage 4. Stage 4 is the most advanced stage of lymphoma. Lymphoma that has started in the lymph nodes and spread to at least one body organ outside the lymphatic system (for example, the lungs, liver, bone marrow or solid bones) is advanced lymphoma.
What is diffuse large B cell lymphoma?
Diffuse large B-cell lymphoma (DLBCL) is a type of blood cancer. Lymphomas are the most common type of blood cancers. There are two types of lymphoma: Hodgkin’s and non-Hodgkin’s. Diffuse large B-cell lymphoma is a non-Hodgkin’s lymphoma (NHL).
What makes a DLBCL different from other lymphomas?
The following features are what make a DLBCL different than other lymphomas: It comes from abnormal B-cells. These B-cells are larger than normal B-cells. The abnormal B-cells are spread out instead of grouped together. The abnormal B-cells will destroy the structure of the lymph node.
How often do you need to take a PET scan for DLBCL?
Advanced DLBCL is treated with the same R-CHOP combination of chemotherapy and immunotherapy medications. However, advanced DLBCL requires more rounds of the medications that are administered every three weeks. Advanced DLBCL will usually need six to eight rounds of the treatment. Your doctor will usually take another PET scan at the midway point of treatment to make sure it’s working effectively. Your doctor may include additional rounds of treatment if the disease is still active or it returns.
How to diagnose DLBCL?
DLBCL is diagnosed by removing part or all of the lump, swollen lymph node, or area with the abnormalities and doing a biopsy on the tissue. Depending on various factors, including the location of the affected area, this procedure may be done under general or local anesthesia.
What are the stages of DLBCL?
The stages for DLBCL are as follows: Stage 1. Only one region or site is affected; this includes lymph nodes, lymph structure, or extranodal sites. Stage 2. Two or more lymph node regions or two or more lymph node structures are involved. At this stage, the involved areas are on the same side of the body.
What type of lymph node is most common in DLBCL?
However, there are some less common types you may want to be aware of. These less common types of DLBCL are: central nervous system lymphoma. T-cell/histiocyte-rich large B-cell lymphoma.
What does the letter B mean in a stage?
These stages will also be accompanied by either an A or B after the stage number. The letter A means you are not having the common symptoms of fever, night sweats, or weight loss. The letter B means that you are having these symptoms.
What is the treatment for diffuse large B cell lymphoma?
The standard treatment for the vast majority of patients with diffuse large B-Cell lymphoma has been a combination called R-CHOP for about the past 20 years. For about 20 years before that it was just CHOP without rituximab (Rituxan). So that's a long time we've had this standard therapy. And the reason it's been around for quite a long time is that it works in the majority of patients and subsequent attempts to try and improve upon it or to replace it haven't been able to show a significant advantage.
Is there hope for a second line of lymphoma?
Yeah. So in the second line for diffuse large B-Cell lymphoma, there is still hope for cure. However, the odds have declined. The odds are not as good. If the cancer has already shown itself to be resistant to the first line of treatments, sometimes that resistant trick that it had up its sleeve might apply to the second line or beyond.
Is large cell lymphoma curable?
The good news about large cell lymphoma is that it is a potentially curable cancer. And the majority of patients are cured with their first treatment, in that there's no relapse that the cancer doesn't come back, that it's gone for good.
What is diffuse large B lymphoma?
3 Early studies of therapy for patients with diffuse large B-cell lymphoma contained some patients with aggressive T-cell lymphoma, as these were lumped together in the Working Formulation and some older classifications. The correct diagnosis today is diffuse large B-cell lymphoma, as used in the World Health Organization (WHO) classification ( Table 1 ). 4 However, we know that this is still a heterogenous group that includes lymphomas with a wide variety of morphologic appearances ( Table 2 ), protein-expression patterns, and gene-expression patterns. For example, patients with diffuse large B-cell lymphoma can be divided into at least 3 clinically relevant groups using gene-expression profiling. 5,– 7 These include the germinal-center type, the activated B-cell type, and mediastinal large B-cell lymphoma ( Table 3 ). A few patients will not easily be classified into these categories. 8 Mediastinal large B-cell lymphoma represents less than 10% of all large B-cell lymphomas, occurs primarily in young women, and always presents with a mediastinal mass. The gene-expression profile is similar to that seen in classical Hodgkin disease. 7, 9 The other 2 types of diffuse large B-cell lymphoma, and those not easily classified, have a median age at presentation in the 60s, a male predominance, and can present at essentially any site in the body. 8 They will be the major focus of this paper.
What is the future of B cell lymphoma?
Advances in functional imaging will change staging and restaging and may make other tests obsolete. Further understanding of the genetic subtypes and the associated patterns of protein expression is likely to lead to individualized therapy based on knowing that lymphomas expressing certain proteins (ie, associated with activation of specific metabolic pathways) are particularly likely to respond to specific agents. Among the first hints at this approach are the apparent disproportionate benefit of patients with the activated B-cell type of diffuse large B-cell lymphoma from treatment with rituximab 83 and the rare patient with a durable response to a salvage regimen after failing CHOP plus rituximab. We already cure a significant proportion of patients with diffuse large B-cell lymphoma. Almost certainly this proportion will continue to rise.
What is stage 1 diffuse lymphoma?
Patients with stage I diffuse large B-cell lymphoma ( ie, involvement of only one lymph-node region or isolated organ involvement) fit into this category of localized disease ; however, selected patients with stage II (ie, 2 adjacent lymph-node regions involved or organ involvement with involvement of regional lymph nodes) who could have their disease encompassed in one radiotherapy port might be approached in a similar manner. These patients were once treated with radiotherapy alone and a few were cured. 28 The addition of adjuvant chemotherapy following the radiation improved treatment outcome, 29 but an abbreviated course of chemotherapy followed by radiation became the most popular treatment. 30 A study done by the Southwest Oncology Group in the United States showed superiority of an abbreviated course of CHOP (cyclophosphamide, doxorubicin, vincristine, prednisone) followed by radiation over a complete course of CHOP alone. 31 This became and has remained the standard treatment in the United States. A more recent Eastern Cooperative Oncology Group study suggested benefit of adjuvant radiation after 8 cycles of CHOP. 32 However, selected patients in whom radiation might be unusually problematic (eg, young women in whom the treatment field would involve the breast or patients of any age in whom salivary gland treatment might lead to a dry mouth and loss of teeth) are often treated with a complete course of chemotherapy alone.
What is the fifth most common cancer?
View Large. Lymphomas are the fifth most common systemic cancer, with the most common subtype being diffuse large B-cell lymphoma followed by follicular lymphoma and Hodgkin lymphoma. Diffuse large B-cell lymphoma represents approximately 30% of all lymphomas and is the most common subtype throughout the world.
Can diffuse B cell lymphoma be recurrent?
A major mistake to avoid in following patients with diffuse large B-cell lymphoma in complete remission is to initiate therapy for apparent relapse without a biopsy. While most patients with new lymphadenopathy will have recurrent lymphoma, it is certainly not true for all.
Is rituximab approved before or after the date of approval?
The progression-free survival of patients treated in British Columbia before or after the approval of rituximab for general use. A few patients received rituximab before the date of approval and some patients did not receive the drug after the date of approval; however, all patients are included.
Can testicular lymphoma spread to the testis?
Patients with localized disease involving certain organs need modifications of the general plan. Patients with testicular lymphoma have a predilection for the disease to spread to the opposite testis and to the central nervous system. 37 Central nervous system involvement can be meningeal or parenchymal.
