Immediate toxicity during fractionated total body irradiation as conditioning for bone marrow transplantation.
BACKGROUND
Total body irradiation followed by bone marrow transplantation is well established as a part of the conditioning regimen in high dose therapy. The immediate tolerance of fractionated total body irradiation (FTBI) was investigated prospectively.


METHODS
From January 1995 to December 1998 162 patients received a FTBI, 6x2 Gy on 3 consecutive days, lung dose 10 Gy, for allogeneic (n=112) or autologous (n=50) bone marrow transplantation. High dose chemotherapy (mostly Cyclophosphamide) was administered after the FTBI. A standardized supportive therapy was administered. The immediate toxicity of FTBI was evaluated prospectively prior to each radiation fraction using a defined questionnaire.


RESULTS
Main symptoms distressing the patient during irradiation period were gastrointestinal symptoms like nausea and emesis. The prevalence of nausea per fraction increased to 26.1% after the 4th fraction, with a significant higher prevalence in children younger than 10 years at 1st and 2nd fractions. 42.6 and 22. 8%, respectively, of all patients complained of nausea and episodes of emesis, during FTBI. Mild xerostomia and parotiditis were observed in 29.9 and 7.1% of all patients. Further gastrointestinal side effects during FTBI were loss of appetite in 16.0%, indisposition in 25.3%, mild oesophagitis in 3.7% and diarrhoea in 3. 7% of the patients. During FTBI 41.4% of the patients developed a temporary skin irritation (mild erythema). Pruritus was registered in 3.7% of the patients. Headache was observed in 14.8% and Fatigue syndrome in 49.2% of women and 28.3% of men (P<0.005).


CONCLUSIONS
FTBI is a well tolerated therapeutic regimen in high dose therapy. The 162 patients investigated revealed no severe immediate side effects.
