In patients, who do not respond satisfactorily to treatment, high-dose therapy with stem cell transplantation and donor lymphocyte infusion (DLI) or specific immunotherapy (e.g., EBV-specific cytotoxic T-lymphocytes, CTL) may be considered

The risk of a second malignancy is high after Hodgkin disease (see below)

7.14Side Effects and Sequelae

Initially high susceptibility to infection

Herpes and varicella-zoster infections after irradiation in 30–40% of patients

7.14.1 Biochemical or Clinical Hypothyroidism

After irradiation in the cervical region, often elevation of the serum TSH level

with or without T3 and T4 elevation within the first 6 years after irradiation, i.e., biochemical hypothyroidism

Thyroxine substitution is necessary when biochemical manifestations of hypothyroidism occur (for prevention of hypophysial hyperplasia)

7.14.2 Gonadal Dysfunction

In adolescent girls after irradiation of the retroperitoneal region, there is secondary amenorrhea and decreased fertility. Preventive ovariopexy before irradiation is sometimes practiced

In adolescent boys receiving procarbazine therapy, azoospermia is often persistent; serum levels of luteinizing hormone (LH) and follicle-stimulating hormone (FSH) are increased, and serum testosterone level is decreased. Avoid procarbazine; cryopreserve sperm before treatment

7.14.3 Decrease in Bone Growth of Irradiated Area

Irradiation in children during periods of rapid growth results in diminution of bone growth: seated height is less than 1–3 standard deviations from the norm

With partial irradiation of vertebral bone, scoliosis occurs

7.14.4 Pneumonitis and Pericarditis

After mediastinal involvement, pneumonitis, and/or pericarditis

After bleomycin therapy, fibrosis of the lung

7 Hodgkin Disease

7.14.5 Infection After Splenectomy

Without prophylactic measures (see below), life-threatening infections, with a fatality of about 4%

Mainpathogens:Diplococcuspneumoniae,Haemophilusinfluenzae,Streptococci, Neisseria meningitis

Prevention: polyvalent vaccination, continuous prophylaxis with penicillin, emergency card for the patient

7.14.6 Secondary Tumors

Secondary tumors are common after Hodgkin disease, owing to the concomitant immunodeficiency and the effects of radiation and chemotherapy

The frequency is 8–16% within 10–20 years and later between 18% and 31% after diagnosis of Hodgkin disease

Main secondary tumors: Non-Hodgkin lymphoma, leukemia (mostly acute nonlymphatic leukemia); solid tumors include sarcomas, breast cancer, and thyroid cancer
