• Hodgkin’s lymphoma
        • Follicular B cells undergo a transformation to malignant cells. (MCQ)
        • Four subtypes based on histology of lymph node and cell type: (MCQ)
          • Lymphocyte predominant
          • Nodular sclerosing:
            • Most common type(MCQ)
            • typically presents as cervical lymph node enlargement or mediastinal mass
          • Mixed cellularity
          • Lymphocyte depleted:
            • Rare, worst prognosis (MCQ)
            • Disease with bimodal distribution having peaks in 30s and 70s
            • May have an association with Epstein–Barr virus (EBV) (MCQ)
        • Clinical
          • Presents with asymptomatic lymph node enlargement or CXR showing mediastinal mass(MCQ)
          • “B” symptoms (MCQ)
            • occur in patients with more widespread disease.
            • These include fever, night sweats, weight loss, and shortness of breath.
        • Diagnosis
          • Lymph node biopsy
          • Presence of Reed–Sternberg cells is required for diagnosis. (MCQ)
        • Treatment
          • Curable depending on stage.
          • Based on staging and pathology, both chemotherapy and radiotherapy are utilized(MCQ)
          • prognosis is dependent on extension of disease.
          • Generally, if the lesion is small and only on one side of the diaphragm, radiation is used alone. (MCQ)
          • Otherwise, add chemotherapy. (MCQ)
      • Non-hodgkin’s lymphoma
        • Most originate from B cells.
        • B cell lymphomas are further classified based on the tissue type origination from lymph node: germinal center, mantle zone, or marginal zone
        • The working classification is most widely used
          • It categorizes lymphoma by low, intermediate, and high grade based on median survival.
        • Signs and symptoms/treatment
          • Lymphadenopathy
          • Fatigue, weight loss, fever, and night sweats are common symptoms.
          • Involvement of mesenteric nodes and extranodal disease is more common. (MCQ)
          • Hepatosplenomegaly
        • Follicular NHL
          • A common presentation of the low-grade follicular lymphomas is asymptomatic, painless, diffuse, long-standing lymphadenopathy in a middle-aged individual. (MCQ)
          • Bone marrow involvement is present in the majority of patients. (MCQ)
          • Treatment includes alkylating agent (cyclophosphamide) and prednisone. (MCQ)
          • Least aggressive (MCQ)
          • median survival is 6 years.
        • Diffuse Large Cell Lymphoma type NHL
          • Most common intermediate-grade lymphoma
          • Diffuse large cell lymphoma may present in a variety of extranodal sites,
          • particularly the gastrointestinal tract and the head and neck. (MCQ)
          • Patients treated with chemotherapy—CHOP (MCQ)
            • Cyclophosphamide
            • doxorubicin
            • vincristine [Oncovin]
            • prednisone
        • Lymphoblastic Lymphoma type NHL
          • High grade lymphomas derived from thymic T-cells(MCQ)
          • Often seen in children
          • Associated with a large mediastinal mass (MCQ)
          • Shows testicular, CNS, and marrow involvement(MCQ)
        • Burkitt’s Lymphoma type NHL
          • High-grade lymphoma
          • more common in children than adults(MCQ)
          • High incidence of bone marrow involvement
          • African type has higher association with EBV and jaw involvement than American type.
          • Marrow with “starry-sky” appearance(MCQ)
          • Treatment includes high-dose cyclophosphamide, methotrexate, and cytarabine and intensive CNS prophylaxis. (MCQ)
          • Unlike Hodgkin’s disease, histology of the nodes is a major predictor of prognosis in NHL. (MCQ)
        • Prognosis
          • Depends on histology of malignancy, not spread of disease.
          • Generally, prognosis is better if histology is nodular or follicular and cell size is small. (MCQ)
          • Prognosis is worse if histology is diffuse and cell size is large. (MCQ)
      • Clinical Pearls
          • Non Hodgkins Lymphoma :
            • Often presents with painless lymphadenopathy(MCQ)
            • Burkitt lymphoma
              • characteristic cytogenetic abnormality of translocation between the long arms of chromosomes 8 and 14 has been identified. (MCQ)
              • The protooncogene c-myc is translocated from its normal position on chromosome 8 to the heavy chain locus on chromosome 14(MCQ)
              • Cells committed to B cell differentiation are likely to have enhanced expression of this heavy chain locus
              • overexpression of c-myc (in its new anomalous position) is related to malignant transformation.
          • Follicular lymphomas
            • the t(14,18) translocation is characteristic (MCQ)
            • results in overexpression of bcl-2, resulting in protection against apoptosis (MCQ)
          • Bone marrow involvement is manifested as paratrabecular lymphoid aggregates
          • In some high-grade lymphomas, the meninges are involved and malignant cells are found with cerebrospinal fluid cytology.
          • The chest radiograph may show a mediastinal mass in lymphoblastic lymphoma. (MCQ)
          • The serum LDH has been shown to be a useful prognostic marker and is now incorporated in risk stratification of treatment
          • Treatment with the anti-CD20 antibody rituximab is a commonly used treatment because of its very low toxicity and avoidance of chemotherapy. (MCQ)
          • Common chemotherapy regimens include
            • fludarabine
            • the combination of cyclophosphamide, vincristine, and prednisone (R-CVP) (MCQ)
            • cyclophosphamide, doxorubicin, vincristine, prednisone (R-CHOP). (MCQ)
          • Radioimmunoconjugates – yttrium-90 ibritumomab tiuxetan(MCQ)
            • fuse anti-B cell antibodies with radiation
            • produce improved results
          • Some patients with clinically aggressive low-grade lymphomas may be appropriate candidates for allogeneic transplantation.
          • Those with lymphoblastic lymphoma receive regimens similar to those used for T cell ALL.
          • Mantle cell lymphoma
            • not effectively treated with standard chemotherapy regimens.
            • Intensive initial therapy including autologous stem cell transplantation has been shown to improve outcomes and is now the standard of care.
            • Reduced-intensity allogeneic stem cell transplantation offers curative potential.
          • Patients with mucosal associated lymphoid tumors (MALT lymphomas) of the stomach
            • treated with combination antibiotics directed against Helicobacter pylori (MCQ)
            • require frequent endoscopic monitoring.
          • Factors that confer adverse prognosis are
            • age over 60 years
            • elevated serum LDH(MCQ)
            • stage III or stage IV disease
            • poor performance status
        • Hodgkin disease
          • The malignant cell is derived from B lymphocytes of germinal center origin.
          • An important feature of Hodgkin disease is its tendency to arise within single lymph node areas and spread in an orderly fashion to contiguous areas of lymph nodes. (MCQ)
          • Only late in the course of the disease will vascular invasion lead to widespread hematogenous dissemination
          • The staging nomenclature (Ann Arbor) is as follows: (MCQ)
            • Stage I, one lymph node region involved
            • Stage II, involvement of two lymph node areas on one side of the diaphragm
            • Stage III, lymph node regions involved on both sides of the diaphragm
            • Stage IV, disseminated disease with bone marrow or liver involvement
            • stage A if they lack constitutional symptoms
            • stage B if 10% weight loss over 6 months, fever, or night sweats are present.
          • Treatment of Hodgkin disease (MCQ)
            • Radiation therapy used as initial treatment only for patients with low-risk stage IA and IIA disease.
              • addition of limited chemotherapy for some patients treated with radiation appears promising.
            • Most patients with Hodgkin disease (including all with stage IIIB and IV disease) are best treated with combination chemotherapy using doxorubicin (Adriamycin), bleomycin, vincristine, and dacarbazine (ABVD)

Laura’s Hodgkin’s Lymphoma Story
Hello 🙂 on Christmas Eve 2010 I was diagnosed with stage 4 Hodgkin’s Lymphoma. This is a video telling you the story of when I had my first symptoms, having tests and getting diagnosed to the stage of treatment I am at now. I hope it allows people to see the positive side to having cancer and the importance of trying to live as normal a life as possible while having chemotherapy.
