- Five Year Survival: 88%
 
- Marginal Zone Lymphoma- Incidence: 2.2 per 100,000
- Five Year Survival: 90%
 
- Precursor B Cell Lymphoma- Incidence: 1.5 pcer 100,000
- Five Year Survival: 69%
 
- Burkitt Lymphoma- Incidence: 0.4 per 100,000
- Five Year Survival: 64%
 
 
- Diffuse Large B Cell Lymphoma
- Non-Hodgkin T Cell Lymphomas (and Natural Killer CellLymphomas)- Peripheral T Cell Lymphoma- Incidence: 1.2 per 100,000
- Five Year Survival: 58%

- Five Year Survival: 91%
 
 
- Peripheral T Cell Lymphoma
IV. Types: Primary Cutaneous Lymphoma
- Primary Cutaneous T-Cell Lymphoma (CTCL, 75% of cases)
- Primary Cutaneous B-cell Lymphoma (CBCL, 25% of cases)- See Cutaneous B-cell Lymphoma
- Primary Cutaneous Follicle Center Lymphoma (PCFCL)
- Primary Cutaneous Diffuse Large B-Cell Lymphoma (PCDLBCL)
- Primary Marginal Zone Lymphoma (PCMZL)
- EBV-Positive Mucocutaneous Ulcer (EBVMCU)
 
V. Risk Factors
- See Lymphoma (for risk factors common to all Lymphomas)
- Male
- White race
- Increasing age
- 
                          Family History
                          - Any first degree relative: 3.1 fold increased risk
- Increased risk is for the particular Lymphoma subtype, that the relative experienced
 
- Exposures- Breast Implants
- Long-term Pesticide exposure
 
VI. Findings: Symptoms and Signs (differentiate from Hodgkin's Lymphoma)
- Presence of Lymphadenopathy draining Waldeyer's ring
- Non-Hodgkin adenopathy occurs anywhere (contrast with supradiaphragmatic involvement in Hodgkin Lymphoma)- Epitrochlear Lymph Nodes
- Mediastinal, abdominal and extranodal involvement- Common at presentation
 
 
- Chest Pain (suggests lung involvement)
- Systemic symptoms are more common in Hodgkin's Lymphoma
VII. Diagnosis: Pathology (Lymph Node histology)
- See Lymphoma
- Diffuse small cleaved cell
- Poorly differentiated Lymphocytes
- Absence of Reed-Sternberg Cells (contrast with Hodgkin Lymphoma)
VIII. Staging
- See Lymphoma
IX. Management
- Combination Chemotherapy and Radiation Therapy- Regimens vary depending on Non-Hodgkin Lymphoma subtype
 
- Chemotherapy: CHOP
- Adjunctive agents used with CHOP- Rituximab (Rituxan, known as CHOP-R when used with CHOP protocol above)- Rituximab is a Monoclonal Antibody that binds CD-20 Antigen on mature B Cells
 
- Bendamustine (Bendeka)
- Lenalidomide (Revlimid)
 
- Rituximab (Rituxan, known as CHOP-R when used with CHOP protocol above)
- Surveillance- See Lymphoma for general surveillance protocols
 
X. Complications
- See Lymphoma for complications shared by all Lymphomas
- Other cancers (related to primary cancer or its treatment)- See Cancer Survivor Care
- Myelodysplasia
- Acute Leukemia
- Thyroid Cancer
- Head and neck cancer
- Breast Cancer
- Bladder Cancer
- Lung Cancer
- Skin Cancer
 
- Treatment related adverse effects- Cardiomyopathy
- Thyroid disorders
- Sexual Dysfunction
 
- Paraneoplastic Syndromes (rare)
XI. Prognosis: International Prognostic Index
- Background- Varies by staging
- Overall five year survival: 69%
 
- Criteria- Age >60 years
- Serum LDH Increased
- Eastern Cooperative Oncology Performance Status >=2- Ambulatory but unable to carry out activities (or limited self care only or bedridden)
 
- Ann Arbor Stage III or IV Disease- Multiple nodal groups on both sides of the diaphragm (may involve Spleen) OR
- Noncontiguous extranodal involvement
 
- Extranodal sites >1
 
- Interpretation- Score 0-1: Five year survival 73%
- Score 2: Five year survival 51%
- Score 3: Five year survival 43%
- Score 4-5: Five year survival 26%
