What is the importance of staging in lymphoma?
Determines the extent and spread of the disease
What is a common imaging study used in lymphoma diagnosis?
CT scans
What is the purpose of a bone marrow biopsy in lymphoma?
To check for bone marrow involvement
What is a genetic factor associated with lymphoma?
EBV driven

What type of lymphoma originates in epithelial cells and is often associated with H. pylori infection?
MALT lymphoma
What type of lymphoma is highly aggressive and more common in children and immunosuppressed individuals?
B-cell lymphoma
What is the primary mechanism by which radiation therapy affects cells?
It breaks DNA, generating free radicals that damage cells.
What are some acute side effects of radiation therapy?
GI tract issues, skin problems, and bone marrow damage.
What is a mandatory part of the initial evaluation for highly aggressive B-cell lymphoma?
Examination of cerebral spinal fluid
What chronic conditions can result from radiation therapy?
Thyroid dysfunction, cataracts, retinal damage, lung fibrosis, and secondary malignancies.
What is the prognosis for Burkitt’s Lymphoma if treatment is delayed?
Adversely affected
How does chemotherapy primarily target cancer cells?
By affecting DNA structure or segregation during mitosis.
What is the typical treatment regimen for highly aggressive B-cell lymphoma?
Combination chemotherapy with high doses of Cyclophosphamide
What are common side effects of chemotherapy?
Diarrhea, mucositis, nausea, alopecia, and infertility.
What is the peak age distribution for Hodgkin’s Lymphoma?
Age 20 and age 65
What is myelosuppression and its consequence in chemotherapy?
It causes pancytopenia, affecting leukocytes, platelets, and RBCs.
What virus is associated with an increased risk of Hodgkin’s Lymphoma?
Epstein-Barr Virus (EBV)
How is anemia associated with chemotherapy managed?
By transfusions of red blood cells.
What has emerged as the dominant treatment option for R/R DLBCL?
Targeted therapies
What is the purpose of stem cell transplantation in cancer treatment?
To replace damaged or destroyed bone marrow.
What factors inform the choice of therapy for R/R DLBCL?
Type and response to prior therapies, timing of relapse, patient age, fitness, comorbidities, disease kinetics, and product availability
What are some reliable sources for information on cancer?
American Cancer Society, Leukemia & Lymphoma Society, Goldman’s Cecil Medicine, UptoDate
What distinguishes autologous from allogenic stem cell transplants?
Autologous uses the patient’s own stem cells; allogenic uses another individual’s stem cells.
Where can one find detailed medical information on Non-Hodgkin’s and Hodgkin’s Lymphoma?
Goldman’s Cecil Medicine and UptoDate
What is the treatment of choice in the third line and later for eligible DLBCL patients?
CAR T-cells
What is the role of CD19-directed CAR T cell therapy?
It targets CD19 on cancer cells using engineered T cells.

It is a bispecific antibody targeting CD20 and CD3.
What are second-line therapy options for patients ineligible or declining CAR T-cell therapy?
Tafasitamab/lenalidomide, polatuzumab/BR, or chemoimmunotherapy (R-GemOx)
What is unique about epcoritamab administration?
It is a subcutaneously administered CD3 x CD20 bispecific antibody.
