[Adults treated as children for acute lymphocytic leukemia--methotrexate, late effects and quality of life]. / Voksne behandlet for akutt lymfatisk leukemi som barn--metotreksat, seneffekter og livskvalitet.

From 1975 to 1980, 153 Norwegian children were diagnosed with acute lymphocytic leukaemia. In 1995, all 98 survivors were studied and compared to matched family controls. 132 children were treated with the national protocol. Of these, 93 (70.5%) were survivors at the time of the study. The remaining five survivors were treated with different treatment schemes. The national protocol included methotrexate infusions combined with intrathecal methotrexate as prophylactics against neuroleukaemia, instead of the irradiation. Neither doxorubicin nor cyclophosphamide were included. In this study, a questionnaire was used that covered demographic data, quality of life, and medical information the response rates were 96% (94 persons) for survivors and 92% (90 persons) for family controls. Information was also obtained for the remaining four survivors. No significant differences were found between survivors and controls with regard to quality of life and demographics, with one exception, Somatisation on the GHQ-28. Hospital records of all patients were checked for possible late effects. One case of serious sequela (hemiparesis during therapy) was found, probably related to methotrexate therapy. Seven other serious, possible sequelae were recorded, but probably not related to methotrexate. There were no cases of secondary malignant neoplasm.

Long-term survival and quality of life in patients treated with a national all protocol 15-20 years earlier: IDM/HDM and late effects?

In a follow-up matched control study the 93 (70.5%) survivors of 132 children treated with a national protocol for acute lymphoblastic leukemia (ALL) and 5 survivors of the other 21 cases of ALL in childhood diagnosed in the same period were evaluated. Thus it was also a population-based study. The national treatment protocol was used in the period 1975-1980. Methotrexate (MTX) infusions combined with intrathecal MTX were used as prophylaxis against neuroleukemia instead of irradiation. Neither doxorubicin (Adriamycin) nor cyclophosphamide was used in the protocol. A questionnaire covering demographic data, number of offspring, learning problems, level of athletic performance, education, and work status as well as medical information was used. Forms were received from 94 (96%) of the 98 adult surviving cases and corresponding controls in the family. Interviews were performed in the remaining four cases (4%). There were no statistical differences between the two groups with respect to physical and mental health and quality of life. Hospital records of all patients were also checked for possible late effects. There was no definite case of secondary malignant neoplasm; however, there was one case of prolactinoma and only one case of serious sequelae (hemiparesis during therapy), probably due to intrathecal and intravenous MTX.
