Lymph node biopsy Biopsy of easily accessible largest node. A complete node is best. And more than one node Axilla and groin are avoided. To be delivered immediately without fixation to path lab. Cell suspensions of fresh tissue for flow cytometry immunotyping, cell kinetics analysis and molecular analysis. Touch imprint cytology is for comparing bone marrow and nodal cytology. A portion is snap frozen for molecular genetics and for immunohistochemistry. A portion is fixed and processed for morphological study.
Diagnosis of NHL lymphoma depends on finding abnormal numbers of lymphocytes that are destroying normal architecture of lymphoid tissue or invading non lymphoid tissue or both. Evaluation

The cells are examined to determine what antigens are expressed on the surface of the cells by using antibodies that bind to those antigens. Helps determine the type of lymphoma with far greater accuracy than just examining the biopsy under the microscope. A chart of which antigens are typically positive or negative is on CD chart.( Cluster Differentiation ) Immunohistochemistry
Individual cells are separated and examined. Flow cytometry identifies types of lymphoma from FNAC specimens Flow Cytometry
FNAC To diagnose relapse Flow cytometry possible with FNAC Inaccessible nodes like abdominal and retroperitoneal nodes can be targeted under CT guidance for FNAC
Why Immuno phenotyping To differentiate a lymphoma from poorly differentiated carcinoma To differentiate a lymphoma from a reactive lesion (monoclonal) Classification of lymphoma
Treatment of lymphoma Staging work Up Treatment Staging work Up Treatment
X-ray chest, CT chest and CT abdomen Bone marrow biopsy. PET scan MRI CSF analysis Staging W ork Up
Cotswold modifications X Massive mediastinal disease has been defined by the Cotswold meeting as a thoracic ratio of maximum transverse mass diameter greater than or equal to 33% of the internal transverse thoracic diameter measured at the T5/6 intervertebral disc level on chest radiography.or 10 cm The number of anatomic regions involved should be indicated by a subscript (eg, II 3 ) Stage III 1 Stage III 2 Stage III may be subdivided into: III 1, with or without splenic, hilar, celiac, or portal nodes; III 2, with para-aortic, iliac, mesenteric nodes CS \ PS CR Staging should be identified as clinical stage (CS) or pathologic stage (PS) A new category of response to therapy, unconfirmed/uncertain complete remission (CR) can be introduced because of the persistent radiologic abnormalities of uncertain significance
The treatment and prognosis depends on stage patient performance status the characteristic of lymphoma.
International Prognostic Index for Hodgkins lymphoma 1- Serum albumin < 4 gm/dl 2- Hemoglobin level below 10.5 gm/dl 3- Male gender 4- Stage IV disease 5- Age 45 years 6- WBC of 15,000/mm²7- Lymphocyte count 600/mm² or 8% of WBC
International Prognostic Index for Non Hodgkins lymphoma Age> 60 years Performance status>2 LDH> than normal Ann Arbour stage III or IV > 2 Extranodal sites

Hodgkins lymphoma usually arises in lymph nodes and spreads to contiguous groups. Extranodal presentation are rare. Treatment is by stage of disease and prognostic factors
Treatment of lymphoma Treatment modality radiotherapy chemotherapy combination therapy high dose chemotherapy with bone marrow transplant monoclonal antibody RITUXIMAB
Treatment of Hodgkins lymphoma With appropriate treatment about 85% of patients with Hodgkin disease are cured
Treatment of Hodgkin Lymphoma Radiation therapy alone in special circumstances Chemoradiotherapy ABVD for two to four cycles plus involved field radiotherapy(20 Gy or 30 Gy). Chemotherapy alone ABVD for four to six to eight cycles. (ABVD: doxorubicin plus bleomycin plus vinblastine plus dacarbazine BEACOPP (increased dose). (bleomycin plus etoposide plus doxorubicin plus cyclophosphamide plus vincristine plus procarbazine plus prednisone
Radiation therapy Extended field mantle field paraaortic field pelvic field CURRENT TREND Involved field radiotherapy Neck Mediastinum Axilla Paraaortic inguinal
Complications of treatment Second malignancy Cardiac dysfunction Lung fibrosis sterility In Hodgkins disease current trend is less aggressive treatment to minimise complications
Chemotherapy, radiotherapy and combined modality for Hodgkin's disease, with emphasis on second cancer risk Cochrane Reviews For early-stage patients chemoradiotherapy resulted in longer survival and longer HD-free survival than either RT or CT alone Second malignancy (SM) risk was lower with CRT than with RT For advanced stages no difference in survival between CRT and CT alone was established
Treatment of non-Hodgkin lymphoma (NHL) depends on the histologic type and stage.
Treatment of Non Hodgkins lymphoma Watchful waiting Chemotherapy with radiation therapy. Rituximab, an anti-CD20 monoclonal antibody, either alone or in combination with chemotherapy. R-CHOP (four to eight cycles). R-CHOP (three to eight cycles) plus IF-XRT. Autologous BMT or peripheral stem cell transplantation or allogeneic BMT for patients at high risk of relapse is under clinical evaluation
Cochrane Summary improved survival of follicular and in mantle cell lymphoma when treated with R-chemo compared to chemotherapy alone. no benefit for high-dose chemotherapy with stem cell transplantation as a first line treatment in patients with aggressive NHL. IFN as maintenance therapy for FL improves progression-free survival. A net benefit for overall survival is less evident
HIV associated lymphoma HIV-associated, non-Hodgkins lymphoma occurs in 5-10% of individuals with HIV infection virtually all of B-cell origin. Most are intermediate- or high-grade lymphomas Complete response occurs in 33-62% of patients. Relapse occurs in 25% of complete responders within 6 months. Median survival is 4-8 months, with about half dying of lymphoma and half of opportunistic infection.
Lymphoma is the most common small bowel malignancy in the pediatric age 50-93% of patients have intestinal lymphomas located in the ileocecal region. a history of nonspecific chronic abdominal pain common can present acutely as appendicitis or intussusception

Summary Management of lymphoma needs a multidisciplinary approach with a need to keep abreast of evidence based medicine. Lymphoma is associated with immuno compromised states Surgeon s role in diagnosis of lymphoma. In treatment of lymphoma in extranodal sites (GI tract emergencies).
