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%)
