BACKGROUND: It has been indicated in several instances that tall stature is also an important risk factor in the development of osteosarcoma. This relationship between height and osteosarcoma is substantiated even more by the increasing evidences being put forth in the recent literature on dependence of certain tumors on the growth factors and their receptors, acting through autocrine or paracrine mechanisms. There has been no study on the Indian population that attempts to define such a relationship. PURPOSE: The primary objective of this study was to define relationship between height of patients and osteosarcoma at the time of diagnosis in the Indian population. MATERIALS/ METHODS: Retrospective data was collected from the old hospital records. Height of patients at the time of diagnosis was compared with expected height of patients of the same age with reference to the standardized growth charts provided by the Indian Academy of Paediatrics. RESULTS: Out of 98 patients, there were 65 male and 33 female patients with M: F ratio being 1.97:1. The mean age at diagnosis was 17 (SD = 8) years with range of 5-55 years (median = 17 years). Height of the patients at the time of diagnosis was 155.18 (SD = 15.47) cm with range of 115 cm-184 cm (median = 159 cm). Overall, patients with Osteosarcoma were found to be shorter than the expected height deduced from the national growth charts. When patients were divided into two groups of those who were of growing age and those who had completed growth, results were similar. CONCLUSION: The observation that majority of patients with osteosarcoma in our study were stunted, is an important finding. It could be deduced from this observation that these patients are unable to mount the usual biological response to the overstimulated growth as part of tumorigenesis in osteosarcoma. This could point to a different scenario in the Indian population and more studies need to be carried out with larger number of patients to further elaborate on this observation.
