Objective To analyze the effect of AP chemotherapy protocol combined with surgery for primary osteosarcoma of bone in the extremities. Methods Between January 2008 and November 2011, a total of 30 patients were initially diagnosed as primary osteosarcoma of extremity. 20 patients with complete data and follow-up materials were collected. There were 12 males and 8 females. The average age of patients was 19 years ( range;9-38 years ). The distal femur was affected in 10 patients, the proximal tibia in 7 patients and the proximal humerus in 3 patients. According to Enneking staging classification, all of the patients were at stage II B. Preoperative pathological subtypes diagnosed by biopsy were listed as follow:osteoblast in 8 patients, chondroblasts in 6, fibroblasts in 2, small cell in 2, and telangiectasis in 2. All of the patients were treated by AP chemotherapy protocol combined with surgery. Results The mean time of the follow-up was 35.6 months ( range;12-55 months ). Patients treated with limb-salvage surgery amounted for 18 cases and amputation for 2 cases respectively. The instant limb-salvage rate was 90%. 7 patients died of pulmonary metastasis, while 5 of which died within 2 years after the surgery. 2 patients experienced local recurrence at 10 months and 12 months after surgery respectively, with the recurrence rate of 10%. 1 of them died , and the other was still alive with tumors at final follow-up. The 3-year overall survival rate was 66%by Kaplan-Meier analysis. At final follow-up, 3 out of 12 cases died in the standard chemotherapy group and 4 out of 8 cases died in the non-standard chemotherapy group, with the survival rates were 75%and 50%respectively. The average Musculoskeletal Tumor Society ( MSTS ) score was 25.3 ( range, 23-27 ). Conclusions The survival rate and limb-salvage rate are fairly satisfactory when combining AP chemotherapy protocol with surgery in the treatment of primary osteosarcoma of the bone. AP chemotherapy protocol is a practicable chemotherapy protocol for primary osteosarcoma of the bone.
