Abstract:
[Objective]To analyze factors related with surviving rate and to evaluate effectiveness of the adjuvant chemotherapy in the treatment of osteosareoma.[Method]Eighty-four patients aging from 9 to 47 years(averaged,21 years)were analysed respectively:52 of them were male and 32 were female.The tumors were located at the femur in 42,the tibia in 29,the humerus in 13.There were 22 patients classified as stage ⅡA and 62 patients as ⅡB.The pathological study,of subtype of osteosarcoma revealed that 47 were osteoblastic,11 chondroblastic,19 fibroblastic and 7 other subtypes.There were 46 patients who received the chemotherapy;38 patients without chemotherapy,49 of the 84 patients treated surgically had limb salvage procedures,35 had amputations.Multivariate analsis was done by using the proportional hazards model of Cox,categoric data were analyzed by using the chi-square statistic.[Result]All cases were followed up from 6 to 74 months(with an average of 25.5 months).Cox model analysis showed that age,sex,site,and subtype were not significant prognostic variables in this group of patients;the significant affecting prognosis in patients was Enncking staging and chemotherapy.Chi-square showed significant difference in the higher metastasis rates of lung in the group without chemotherapy than in those with chemotherapy group(P
