Abstract
Objective
Some evidence exists that patients with osteosarcoma and Ewing sarcoma are taller than the general population. However, previous studies are under-powered, lack comprehensive data and show inconsistencies.
Methods
Relevant studies linking osteosarcoma and Ewing sarcoma with height at diagnosis were identified in two major online databases, Medline (1950 to 2009) and Embase (1980 to 2009). Outcomes in individual studies were reported as standard deviation (SD) scores or percentages of study population with height at diagnosis above the median of the reference population. We performed separate random-effects meta-analyses for each outcome and tumour type.
Results
14 studies examined the height of patients with osteosarcoma or Ewing sarcoma. Meta-analyses on SD scores found patients with osteosarcoma were 0.260 SD (95% CI: 0.088–0.432) taller than the reference population (five studies). A meta-analysis on percentages found 62% (95% CI: 57%–67%) of patients were estimated to have a height above the median (six studies). Patients with Ewing sarcoma were 0.096 SD (95% CI 0.004–0.188) taller (four studies). Only one study reported the percentage of Ewing sarcoma patients with height above the median.
Conclusion
The average height of patients with osteosarcoma, but not Ewing sarcoma, was significantly above the average height of the reference population by 2–3 centimetres. The observed differences indicate the involvement of pubertal longitudinal bone growth in osteosarcoma development while different biological pathways could be relevant for Ewing sarcoma.
