Does Reconstruction with Reimplantation of Sterilized Tumor Bone Provide Survival Benefit in Diaphyseal Osteosarcoma?

Table 2

Summary of outcome variables in the reimplantation and the non-reimplantation group.

Variable	Reimplantation group (n = 24)	Non-reimplantation group (n = 37)	values
Local recurrence only	1 (4%)	1 (2.7%)
Metastasis only	6 (25%)	18 (43%)
Local recurrence with metastases	2 (8%)	0 (0%)
Died of disease	7 (29%)	16 (43%)
Alive with disease	2 (8%)	3 (8%)
Continually disease free	15 (62.5%)	18 (48.64%)
5 yr LRFS	85% (range 60–90)	97 (range 80–95)	0.17
5 yr MFS	63 (range 40–78)	54 (range 35–70)	0.44
5 yr OS	70 (range 50–85)	58 (range 40–70)	0.39

LRFS: local recurrence-free survival; MFS: metastasis-free survival; OS: overall survival.
