Abstract	To summarize the experience in intraarterial neoadjuvant chemotherapy for extremity osteosarcoma. Between January 2002 and December 2007,111 patients with stage IIB extremity osteosarcoma received preoperative intraarterial therapy with subcutaneous implantation of chemotherapy pump as well as en bloc resection, and postoperative adjuvant chemotherapy. There were 63 males and 48 females with an average age of 18 (range, 14 ~ 39 years). The time from symptom onset to hospitalization varied from several days to 6 months. The induction chemotherapy regimen includes: epirubicin [50 ~ 70 mg/m(2) by 4-hour intraarterial infusion/day for 3 day] and cisplatin [100 ~ 120 mg/m(2) by 2-hour intraarterial infusion/day for 3 days] repetitively every 2 ~ 3 weeks. Among which 24 cases only received two cycles induction chemotherapy was set to nonstandard chemotherapy group and 87 cases received three to six cycles induction chemotherapy set to standard chemotherapy group. The number of preoperative chemotherapy-cycles of standard chemotherapy group depends on the clinical and radiographic evaluation of chemotherapy efficacy. Median follow-up time was 28(8 ~ 48) months. The rate of limb preservation surgery was 89.53% (77/86) in standard chemotherapy group,and was 37.5% (9/24) in nonstandard chemotherapy group. Kaplan-Meier survival analysis showed that the 3-year overall survival rate and disease free survival rate of all the 111 cases were 68.3% and 65.9% respectively. There were significant differences in overall survival rate (38.9%, 80.0%, P = 0.000), disease free survival rate (30.1%, 79.5%, P = 0.000), distant metastasis rate (66.67%, 16.09%, P = 0.0000) and local recurrence rate (58.33%, 13.79%, P = 0.0000) between nonstandard chemotherapy group and standard chemotherapy group. Standard intraarterial neo-adjuvant chemotherapy was more effective than nonstandard intraarterial induction chemotherapy to stage IIB extremity osteosarcoma.
