Introduction
• Non-Hodgkin’s lymphomas (NHLs) are a heterogeneous group of lymphoid malignancies that differ greatly in clinical presentation, prognosis, and response to therapy.
![Page 3: Seminar nhl](https://reader035.vdocuments.us/reader035/viewer/2022081507/58acdb1f1a28ab36288b64f1/html5/thumbnails/3.jpg)
Epidemiology
• Non-Hodgkin lymphoma (NHL), accounts for about 4% of all cancers. This the sixth most common malignancy in men and fifth most common in women.
• In India incidence is 5.1 per 100000.• In USA incidence is 19.1 per 100000.• More than 95% of cases occur in adults. • NHL can occur at any age, but about half of
patients are older than 66

Risk Factors
• For the majority of patients not clear.• A minority of patients of FL or chronic
lymphocytic leukemia (CLL) have the risk of histologic transformation of about 5–7% per year.
• In CLL, histologic progression to DLBCL is called Richter’s transformation.
• Studies of survivors of atomic bombs and nuclear reactor accidents, (thyroid cancer, and non-Hodgkin lymphoma.)

• Other documented risk factors for DLBCL include HIV disease.
• Some autoimmune diseases such as rheumatoid arthritis, systemic lupus erythematosus (SLE or lupus), Sjogren disease, celiac sprue (gluten-sensitive enteropathy).
• Translocations, most cases of follicular lymphoma have a translocation between chromosomes 14 and 18, which turns on the bcl-2 oncogene.

Certain infections • The human T-cell leukemia/lymphoma virus (HTLV-1) and
the Epstein- Barr virus (EBV)• Human herpes virus 8 (HHV8) can also infect lymphocytes.
Another name for this virus is Kaposi sarcoma- associated herpes virus (KSHV).
• Helicobacter pylori (MALT). • Chlamydophila psittaci (ocular adnexal marginal zone
lymphoma• Campylobacter jejuni (MALT)• HCV (splenic marginal zone lymphoma)• Breast implants (some women develop anaplastic large cell
lymphoma in the scar tissue around their breast implant)

Initial evaluation
• A thorough physical exam with attention to nodal areas and assessment of performance status.
• Laboratory studies including a CBC with differential, LDH, uric acid, calcium, liver function tests as well as an HIV test and other viral markers.
• Imaging studies including USG,CT scans of the neck, chest, abdomen, and pelvis. (PET scans are routinely performed)
• Assessment of ejection fraction with echocardiography
![Page 19: Seminar nhl](https://reader035.vdocuments.us/reader035/viewer/2022081507/58acdb1f1a28ab36288b64f1/html5/thumbnails/19.jpg)

EXCISIONAL LN BIOPSY• Histologic evaluation includes:
– Assessment of the morphology;– Pattern of lymph node involvement.
• Morphology: Morphological changes have prognostic impact.
• Pattern(s) of lymph node involvement:– Nodular/follicular pattern – Diffuse pattern – Change from a nodular to a diffuse pattern in adjacent nodes – Change from a lower to a higher grade of involvement within a single
node

DIFFUSE LARGE B-CELL LYMPHOMA
• The two most common types of NHL, diffuse large B-cell lymphoma and follicular lymphoma (FL), account for nearly 2/3 of the cases.
• Pathological analysis in case of DLBCL will usually show large lymphocytes with nuclei greater than twice the size of normal small lymphocyte nuclei, prominent nucleoli, and basophilic cytoplasm.
• Malignant cells express the B-cell antigens CD19, CD20, CD22, and CD79a.
![Page 23: Seminar nhl](https://reader035.vdocuments.us/reader035/viewer/2022081507/58acdb1f1a28ab36288b64f1/html5/thumbnails/23.jpg)
• About 1 in 3 of these lymphomas is only in one part of the body (localized) when it is found. Lymphomas are easier to treat when they are localized than when they have spread to other parts of the body.
• Genetic tests have shown that there are different subtypes of DLBCL. These subtypes seem to have different outcomes (prognoses) and responses to treatment.
• DLBCL is a fast-growing lymphoma, but it often responds well to treatment.
• Overall, about 3 out of 4 people will have no signs of disease after the initial treatment, and many are cured with therapy.
![Page 24: Seminar nhl](https://reader035.vdocuments.us/reader035/viewer/2022081507/58acdb1f1a28ab36288b64f1/html5/thumbnails/24.jpg)
Follicular lymphoma
• About 1 out of 5 lymphomas is follicular lymphoma. The term follicular means that the cells tend to grow in a circular pattern in lymph nodes.
• The average age for people with this lymphoma is about 60. It’s rare in very young people
• Follicular lymphomas are often slow-growing and respond well to treatment, but they are hard to cure.
• These lymphomas may not require treatment when they are first diagnosed. Instead, treatment may be delayed until the lymphoma is causing problems.
• Over time, about 1 in 3 follicular lymphomas turns into a fast-growing diffuse B-cell lymphoma.
![Page 25: Seminar nhl](https://reader035.vdocuments.us/reader035/viewer/2022081507/58acdb1f1a28ab36288b64f1/html5/thumbnails/25.jpg)
Chronic lymphocytic leukemia /small lymphocytic lymphoma
• These are closely related diseases. In fact, many consider them different versions of the same disease. The same type of cancer cell (known as a small lymphocyte ) is seen in both chronic lymphocytic leukemia (CLL) and small lymphocytic lymphoma (SLL).
• The only difference is where the cancer cells are found. In CLL most of the cancer cells are in the blood and bone marrow. In SLL, the cancer cells are mainly in the lymph nodes and spleen. About 5% to 10% of all lymphomas are SLLs.
• Treatment is the same for CLL and SLL.• They are usually not curable with standard treatments, but
depending on the stage and growth rate of the disease, most patients live longer than 10 years..
![Page 26: Seminar nhl](https://reader035.vdocuments.us/reader035/viewer/2022081507/58acdb1f1a28ab36288b64f1/html5/thumbnails/26.jpg)
Mantle cell lymphoma
• Only about 5% of lymphomas are this type. The cell size is small to medium.
• Men are affected most often. The average age of patients is the early 60s. When this lymphoma is diagnosed, it is usually widespread in the lymph nodes, bone marrow, and often the spleen.
• This usually isn’t a very fast-growing lymphoma, but it can be challenging to treat. Newer treatments might be more effective than those used in the past, and may offer a better chance for long-term survival for patients now being diagnosed.
![Page 27: Seminar nhl](https://reader035.vdocuments.us/reader035/viewer/2022081507/58acdb1f1a28ab36288b64f1/html5/thumbnails/27.jpg)
Marginal zone B-cell lymphomas
• Marginal zone lymphomas account for about 5% to 10% of lymphomas. The cells in these lymphomas look small under the microscope. There are 3 main types of marginal zone lymphomas.
• Extranodal marginal zone B-cell lymphomas, also known as mucosa-associated lymphoid tissue (MALT) lymphomas
• Nodal marginal zone B-cell lymphoma• Splenic marginal zone B-cell lymphoma
![Page 28: Seminar nhl](https://reader035.vdocuments.us/reader035/viewer/2022081507/58acdb1f1a28ab36288b64f1/html5/thumbnails/28.jpg)
Burkitt lymphoma
• This type makes up about 1% to 2% of all lymphomas. It is named after the doctor who first described this. The cells are medium- sized. Another kind of lymphoma, Burkitt-like lymphoma, has slightly larger cells.
• This is a very fast-growing lymphoma. It is linked to infection with the Epstein-Barr virus
• The lymphoma usually starts in the abdomen, where it forms a large tumor mass. It can also start in the ovaries, testicles, or other organs, and can spread to the brain and spinal fluid.
• Close to 90% of patients are male. Although this is a fast-growing lymphoma, more than half of patients can be cured by intensive chemotherapy.

T-cell lymphomas
• T-cell lymphomas make up less than 15% of non-Hodgkin lymphomas. There are many types of T-cell lymphoma, but they are all fairly rare. eg
• Precursor T-lymphoblastic lymphoma• Peripheral T-cell lymphomas • Cutaneous T-cell lymphomas (mycosis fungoides,
Sezary syndrome, and others)
![Page 30: Seminar nhl](https://reader035.vdocuments.us/reader035/viewer/2022081507/58acdb1f1a28ab36288b64f1/html5/thumbnails/30.jpg)

Treatment
The main types of treatment for Non-Hodgkin Lymphoma are:
• Chemotherapy • Immunotherapy • Targeted Therapy • Radiation Therapy• Bone Marrow Transplant In rare cases, surgery is also used.
![Page 34: Seminar nhl](https://reader035.vdocuments.us/reader035/viewer/2022081507/58acdb1f1a28ab36288b64f1/html5/thumbnails/34.jpg)

• Often drugs from different groups are used in combination. One of the most common combination of drugs is CHOP.
• Chemo is often combined with immunotherapy, especially the monoclonal antibody rituximab RCHOP
![Page 36: Seminar nhl](https://reader035.vdocuments.us/reader035/viewer/2022081507/58acdb1f1a28ab36288b64f1/html5/thumbnails/36.jpg)
CHOP
• Cyclophosphamide: 750 mg/m2 IV on day 1• Doxorubicin: 50 mg/m2 IV on day 1• Vincristine: 1.4 mg/m2 IV on day 1 (maximum,
2 mg)• Prednisone: 40 mg/m2 PO on days 1–5Repeat cycle every 21 days upto 6 cycles
![Page 37: Seminar nhl](https://reader035.vdocuments.us/reader035/viewer/2022081507/58acdb1f1a28ab36288b64f1/html5/thumbnails/37.jpg)
CHOP + Rituximab
• Cyclophosphamide: 750 mg/m2 IV on day 1• Doxorubicin: 50 mg/m2 IV on day 1• Vincristine: 1.4 mg/m2 IV on day 1 (maximum, 2
mg)• Prednisone: 40 mg/m2 PO on days 1–5• Rituximab: 375 mg/m2 IV on day 1Repeat cycle every 21 days. Rituximab is to be administered first, followed by cyclophosphamide, doxorubicin, and vincristine.

Non-Hodgkin’s LymphomaAggressive chemotherapy regimens
• Dose-dense CHOP• CHOP-Bleomycin• CEOP-Bleomycin• DexaBEAM• HyperCVAD
![Page 39: Seminar nhl](https://reader035.vdocuments.us/reader035/viewer/2022081507/58acdb1f1a28ab36288b64f1/html5/thumbnails/39.jpg)
It uses high doses of X-rays, gamma rays, or other types of ionizing (damaging) radiation to kill cancer cells. It may be applied to the whole body or to a specific zone.
Radiotherapy
![Page 40: Seminar nhl](https://reader035.vdocuments.us/reader035/viewer/2022081507/58acdb1f1a28ab36288b64f1/html5/thumbnails/40.jpg)
• Although current treatment regimens vary widely among institutions, they commonly include three to eight cycles of R-CHOP, succeeded by IFRT. Radiation dose of 30–36 Gy for 10 fractions is recommended.
• For patients with partial response (PR) to chemotherapy with residual, doses of at least 40 Gy should be considered.
![Page 41: Seminar nhl](https://reader035.vdocuments.us/reader035/viewer/2022081507/58acdb1f1a28ab36288b64f1/html5/thumbnails/41.jpg)
INDICATIONS FOR PALLIATIVE RADIATION IN ADVANCED-STAGE INDOLENT NHL
Palliative low-dose RT for follicular and marginal zone lymphomas (4 Gy in two fractions) often provides local control and relief of symptoms.
![Page 42: Seminar nhl](https://reader035.vdocuments.us/reader035/viewer/2022081507/58acdb1f1a28ab36288b64f1/html5/thumbnails/42.jpg)
Monoclonal antibodies
A number of monoclonal antibody drugs used to treat NHL target the CD20 antigen, a protein found on the surface of B lymphocytes. These include:
• Rituximab • Ibritumomab tiuxetan • Obinutuzumab • Ofatumumab
![Page 43: Seminar nhl](https://reader035.vdocuments.us/reader035/viewer/2022081507/58acdb1f1a28ab36288b64f1/html5/thumbnails/43.jpg)
Primary mechanism of action of Rituximab
• Binds to a protein called CD-20 (located on the surface of B-cells)
• Causes destruction of the B-cells
![Page 44: Seminar nhl](https://reader035.vdocuments.us/reader035/viewer/2022081507/58acdb1f1a28ab36288b64f1/html5/thumbnails/44.jpg)
Radioimmunotherapy with Y-90
• Ibritumomab– Murine monoclonal
antibody parent of Rituximab
• Tiuxetan– Conjugated to
antibody, forming strong urea-type bond
– Stable retention of Y-90
Y-90 radionuclideBeta radiation
Chelator
Monoclonal antibody

Hematopoietic stem cell transplant (HCT)
• Autologous HCT may be beneficial for some patients in complete or near-complete remission after their first chemotherapy regimen
• Autologous HCT may be of benefit for patients who have a CR or PR to second-line chemotherapy for relapsed disease,
• Although treatment-related mortality is approximately 30%, myeloablative allogeneic HCT may be curative in some patients.
• Non-myeloablative (reduced intensity) allogeneic HCT decreases treatment-related mortality and can provide long-term progression-free survival (PFS)

Take Home Message• NHLThe most common types are diffuse large B-cell (~30%) and follicular lymphoma (~25%).
• Biologic CharacteristicsLymphomas are a diverse group of diseases clinically, pathologically, and genetically.

• Staging EvaluationStaging requires a thorough history and physical examination, CBC, LDH level, bone marrow biopsy, CT of the neck, thorax, abdomen & pelvis, and FDG-PET.

• Primary Therapy• Stage I and II follicular lymphomas are treated with IFRT, expecting a
greater than 95% local control rate and 50% long-term disease-free survival.
• Stage III and IV follicular lymphomas are treated with chemotherapy and RT, which are effective in controlling the disease.
• Stage I and II diffuse large B-cell lymphoma are treated with combined modality therapy, with a cure expected in 70% to 90% of patients.
• Stage III and IV diffuse large B-cell lymphoma are treated primarily with doxorubicin based chemotherapy.

• Salvage Therapy• Patients with bulky disease or incomplete
response to salvage chemotherapy receive local RT to sites of disease as planned combined salvage treatment. RT may be delivered before or after autologous stem cell transplantation.
• Patients so treated have a cure rate of 30% to 50%.

• Palliation• Palliative low-dose RT for follicular and
marginal zone lymphomas (4 Gy in two fractions) often provides local control and relief of symptoms
