We studied the long-term pulmonary function of 25 patients who were at least 5 years post-treatment for Hodgkin's disease. The mean age of the patients was 17 years (range 9.5-25 years) at the time of study. Twenty-one of the patients were male. All patients received six courses of COPP chemotherapy and, in addition, 8 of the 25 patients received radiotherapy to the mediastinum in low or moderate doses (20-30 Gy). One patient had symptoms of bronchiectasia. The chest radiographs of nine patients (36%) showed minimal abnormalities. We divided patients into two groups while evaluating their pulmonary function tests according to whether they received mantle irradiation or not. In patients who received mantle irradiation, pulmonary function tests showed a minimal decrease in FEV 1 . The decrease in FEV 1 indicated an obstructive ventilatory defect. We concluded that our treatment protocols for paediatric Hodgkin's disease were curative, well tolerable and might minimize pulmonary functional changes.

Of 806 non-Hodgkin's lymphoma cases, only one primary subconjunctival lymphoma case was observed in Hacettepe Children's Hospital over a period of 16 years. The patient was a 12 year-old-boy with a subconjunctival mass on the upper part of his right eye. Biopsy revealed malignant lymphoma. Extensive investigations disclosed no other site of tumor. He was given the modified LSA2-L2 protocol. He has been in remission for 22 months. This may be the first report of a primary subconjunctival lymphoma in the childhood period.

A case of hyperpyrexia induced by procarbazine in a child with Hodgkin's disease, neurofibromatosis, and pectus excavatum deformity is presented. After the diagnosis of stage IIIS Hodgkin's disease, combined COPP chemotherapy was initiated. One week later she presented with high fever. After a diagnosis of infection was made, chemotherapy was stopped and antibiotics were given. Nearly the same picture recurred three times after reinstituting chemotherapy. On the fourth occasion, the patient had to be hospitalized because of hyperpyrexia and arrhythmia. There was no obvious reason for fever, and cytotoxic-induced fever was considered. The drugs were given one at a time. When a test dose (10 mg) of procarbazine was given, she developed a high fever with severe nausea and vomiting. The reaction was controlled by antihistaminics and steroids. To our knowledge this is the second report on hyperpyrexia due to procarbazine administration.

From January 1983 to December 1986 seventy-six previously untreated children with non-Hodgkin's lymphoma (NHL) were treated by combination chemotherapy. Burkitt's lymphoma patients were ineligible. The treatment regimens include intermittent chemotherapy and for non-localized patients, prophylactic central nervous system chemotherapy. Intrathoracic non-Hodgkin's lymphoma patients also had cranial prophylactic radiotherapy. Sixty-six patients (86.8%) achieved complete remission. Two year failure-free survival rate was 82.1% for localized (stage I and II) NHL and 53.3% for non-localized (stage III and IV) NHL patients. Failure-free survival did not differ significantly for the two major histologic diagnoses, but two year survival rate was lower in diffuse poorly differentiated lymphoblastic than undifferentiated non-Burkitt's lymphoma (50% versus 66.8% respectively). Failure-free survival rate was 53.7% in mediastinal disease and, 73.2% in abdominal disease at 24 months. Relapse rate was higher in mediastinal cases (46.1%) than primary abdominal cases (24.3%) at 24 months. Eleven (13.5%) died of treatment related sepsis. Although the overall survival rate was 72.4% at 2 years we need novel or more intensive programmes for mediastinal and non-localized disease.
