6 Non-Hodgkin Lymphoma

6.8Diagnosis

6.8.1Risk-Adapted Diagnostic Procedure

•Histological diagnosis from lymph nodes, peripheral blood, bone marrow and fluid resulting from pleural effusion or ascites

•In advanced abdominal stage if possible, laparotomy should be avoided in order not to delay chemotherapy

•Compression of airways and/or of superior vena cava: emergency situation, noninvasive biopsy and pretreatment with chemotherapy and radiotherapy

•Morphological, immunophenotypical, and molecular-cytogenetic analyses are required

•For rapid diagnosis and treatment, morphological diagnosis can be adequate

•Serum lactate dehydrogenase (LDH) allows assessment of tumor progression and response to treatment

•Increased serum uric acid levels indicate risk of nephropathy

•Bone marrow aspiration has to be done in at least two different locations

•CSF analysis reveals NHL involvement in about 10% of cases

6.8.2Radiological Diagnosis

•Ultrasound of peripheral, intra-abdominal, and retroperitoneal lymph nodes

•Conventional X-ray or CT of the thoracic and skeletal disease

•MRI for abdominal and CNS disease; if possible, PET or PET/CT

•Bone scan

6.9Staging (Murphy, St. Jude)

IA single tumor (extranodal) or single anatomical area (nodal), excluding mediastinum or abdomen

IIA single tumor (extranodal) with regional node involvement On same side of diaphragm

(a)Two or more nodal areas

(b)Two single (extranodal) tumors with or without regional node involvement

A primary gastrointestinal tract tumor (usually ileocecal) with or without associated mesenteric node involvement; gross complete resection

IIIOn both sides of the diaphragm

(a)Two single tumors (extranodal)

(b)Two or more nodal areas

 

All primary intrathoracic tumors (mediastinal, pleural, thymic)

 

All extensive primary intra-abdominal disease; unresectable

 

All primary paraspinal or epidural tumors regardless of other sites

IV

Any of the above with initial CNS or bone marrow involvement (less than 25%)
