7 Hodgkin Disease

69

 

 

7.7.2 Chemistry

• Serum copper high (differential diagnosis: estrogen induced by contraceptive medication) and serum ferritin high

7.7.3 Immunological Analyses

•Immune response decreased

•Decreased mitogen-induced T-cell function

•Hypersensitivity to T-suppressor cells

•Increased risk of bacterial, fungal, or viral infections, especially after splenectomy

•Herpes zoster virus infection in 35% of patients during or after irradiation therapy

•In children with complete remission, disappearance of immunological deficits after treatment (in contrast to adults)

7.8Radiological Evaluation

7.8.1Chest

•Evaluation by X-ray, computed tomography (CT), or positron emission tomography (PET) and Fluor-Deoxy-Glucose (FDG-PET); these are usually done in sequence but many centers now combine CT with PET scanning

•Enlargement of mediastinal nodes in the anterior and middle mediastinum mostly

•Posterior mediastinal enlargement usually together with retroperitoneal lymph node involvement

•Lung tissue involvement (see above)

•Manifestation of thoracic Hodgkin disease is often associated with nodular sclerosing histology

7.8.2Abdomen

•Ultrasound, magnetic resonance imaging (MRI), and (FDG)- PET for documentation of abdominal involvement

•Lymphangiography is rarely indicated and is contraindicated in patients with mediastinal involvement

•Combination of venocavography and intravenous urography only indicated in unclear retroperitoneal involvement
