2  FBE / CBC  U&E  LFT  ESR  LDH  Beta 2 microglobulin  Protein electrophoresis  HIV and HTLV II serology

3  Look for:anaemia,  WCC, lymphopenia, neutrophilia/ neutropenia, eosinophilia Hodgkin diseaseNHL RBCAnaemia: anaemia of chronic disease / bone marrow infiltration / autoantibodies (positive warm Coombs test) Anaemia: bone marrow infiltration/ autoimmune hemolysis/ bleeding/ anaemia of chronic disease WBCLeukopenia due to bone marrow infiltration Lymphocytosis with circulating malignant cells PlateletPlatelet counts may be increased or decreased Thrombocytopenia due to bone marrow infiltration or autoimmune cytopenias OthersCytopenias: common in advance stages Pancytopenia due to bone marrow infiltration or autoimmune cytopenias

4  Check serum creatitine and renal function: ureteric obstruction secondary to lymph node enlargement can cause renal impairment  Check calcium, phosphate, and sodium  Check renal function prior to treatment Hodgkin diseaseNHL HypercalcaemiaHypercalcaemia (in acute adult T-cell lymphoma) Hypernatraemia Check serum creatinine for nephrotic syndrome (rare) Patient may have renal impairment due to obstruction (lymph node enlargement)

5 Hodgkin diseaseNHL  ALP due to the presence of liver or bone involvement. Abnormal due to hepatic involvement, hypermetabolic tumour growth, chronic inflammation

6  Elevated in Hodgkin's disease and NHL  fairly non-specific and should not be used for screening LDH  Bad prognosis if it is increase in Hodgkin’s disease and NHL

7  may be elevated and correlates with a poor prognosis in NHL

8 Hodgkin diseaseNHL  Increase gamma globulin  Monoclonal gammopathy  Hypogammaglobulinemia

9  HIV serology is done because antiviral therapies can improve disease outcomes in HIV-positive patients in NHL and HD.  In NHL, HIV serology is done for patients with diffuse large cell immunoblastic or small noncleaved histologies.  HTLV II serology is done for adult T-cell lymphoma-leukemia

10  Structural imaging (Conventional method of staging)  CT (neck to pelvis)  MRI  CXR  Functional imaging  PET scan  Gallium scan  Bone scan

11  It is the most widely used test for initial staging, assessing treatment response, and conducting follow-up care  Possible abnormal findings include enlarged lymph nodes, hepatomegaly and/or splenomegaly, lung nodules or infiltrates, and pleural effusions.  Mediastinal lymphadenopathy, is a very common finding in classic Hodgkin disease, although it is uncommon in Nodular Lymphocyte-Predominant Hodgkin's Disease


13  MRI is done when there is a suspicion of CNS involvement eg primary CNS lymphoma, or vertebral body involvement by lymphoma

14  CXR is more indicated for NHL eg for identification of hilar or mediastinal adenopathy, pleural or pericardial effusions, and parenchymal involvement

15  considered to be essential to the initial staging of Hodgkin disease  can be used for the initial evaluation of patients with NHL  more useful for post-treatment evaluation to differentiate early recurrences or residual disease from fibrosis or necrosis.

16  Appears to be sensitive for detecting NHL in extranodal sites  Reliability to detect bone marrow involvement is questioned  Better than gallium and equal to CT to detect disease sites in intermediate to high grade NHL and Hodgkin’s  PET scan has a higher predictive value for relapse than classic CT scan imaging  Scarce availability so x always practical


18  the use is nearly all replaced by PET scan


20  It is done if suspected BM involvement eg bone pain or elevated ALP  In NHL, one lesions are particularly associated with the acute form of adult T-cell lymphoma- leukemia and diffuse large B-cell lymphomas

21  Light microscopy and H&E are the mainstay of pathologic diagnosis  Flow cytometry: marked increased in monoclonal cells indicate lymphoma  Immunoperoxidase: special staining using specific marker antibody to determine the type of lymphoma

22 CellsMarkers T cellCD3, CD4, CD8 B cellCD20, immunoglobulin on surface Hodgkin’s lymphomaCD45 NK cellsCD16, CD56 LymphoblastTerminal deoxynucleotidyl transferase All lymphocytesCD34

23  Lymph node sample  Fine needle aspiration  Needle-core biopsy / incisional biopsy  Excision biopsy  Bone marrow sample  Trephine / biopsy  Aspirate  Biopsy of extranodal sites  Lumbar puncture  Staging laparotomy  Pleural effusion sampling

24 Fine needle aspiration Needle-core biopsy / incisional biopsy Excision biopsy -can be used as initial diagnosis of HD -insufficient for establishing a diagnosis of NHL Has a limited role in establishing a diagnosis of NHL. Essential for diagnosis of HD and NHL

25 Histopathologic image of Hodgkin's lymphoma. CD30 (Ki-1) immunostain.

26 Histopathologic image of Hodgkin's lymphoma. Lymph node biopsy. H & E stain.


28 Malignant B-cell lymphocytes seen in Burkitt's lymphoma, stained with hematoxylin and eosin (H&E) stain

29 Histopathology of diffuse large B-cell lymphoma occurring in the tonsil. H&E stain.

30 Histopathology of diffuse large B-cell lymphoma occurring in the tonsil. CD20 (L26) immunostain.

31  lymphoma in the bone marrow is often patchy, so bilateral bone marrow biopsies is indicated  HD:  Bone marrow involvement is more common in elderly individuals, in patients with advanced-stage disease, in the presence of systemic symptoms, and in patients with a high-risk histology.  A bone marrow biopsy can be omitted in patients with stage I Hodgkin disease (Hodgkin's lymphoma) and some patients with stage II disease without hematologic abnormalities.  For NHL, bone marrow sampling is done for staging rather than diagnosis

32  Sensitive for the presence of lymphoma at light microscopy level when there are sufficient cells to be identified by the pattern they form or number of cells present  Sensitivity can be increased by using CD marker to identify subgroup of lymphocytes, but because lymphocytes are normally present in BM, the pattern and number are important.  PCR to detect presence of translocation or oncogenes can increase the sensitivity and give better measure of prognosis

33  In some patients with NHL, the extranodal sites are the primary presenting sites, and the most common site is the GI tract.

34  CNS involvement with Hodgkin disease (Hodgkin's lymphoma) is exceedingly rare  In patient with NHL, it should be performed if  Diffuse aggressive NHL with bone marrow, epidural, testicular, paranasal sinus, nasopharyngeal involvement, or patient with two or more extranodal sites of disease.  High-grade lymphoblastic lymphoma  High-grade small noncleaved cell lymphomas (eg, Burkitt and non-Burkitt types)  HIV-related lymphoma  Primary CNS lymphoma  Patients with neurologic signs and symptoms

35  involves splenectomy with biopsies of the liver and lymph nodes in the para-aortic, mesenteric, portal, and splenic hilar regions.  Rarely done

36  Sampling of a pleural effusion by thoracentesis and examination of the cells obtained may be useful in the evaluation of Hodgkin disease (Hodgkin's lymphoma).


38 Stage I a single lymph node area (I) or single extranodal site (IE). Stage II 2 or more lymph node areas on the same side of the diaphragm (II or IIE). Stage III lymph node areas on both sides of the diaphragm (III or IIIE or IIIs or IIIS) Stage IVdisseminated or multiple involvement of the extranodal organs. Involvement of the liver or the bone marrow is considered stage IV disease.


40 B The presence of 1 or more of the following:  Fever (temperature >38°C)  Drenching night sweats  Unexplained loss of more than 10% of body weight within the preceding 6 months AAbsence of the above XThe presence of bulky disease EContiguous involvement of extranodal sites (eg, involvement of the lung parenchyma due to direct extension of large mediastinal lymphadenopathy)

41  Large mediastinal adenopathy  An ESR result (a general marker of inflammation) 50 mm/h or higher, if the patient is otherwise asymptomatic OR ESR > 30 if hv B symptoms  More than 3 sites of disease involvement  The presence of B symptoms  The presence of extranodal disease  Age above 50 at diagnosis
