Objective:To analyze the reasons for unplanned resection of soft tissue sarcomas and explore the treatment strategies for cancer surgery. Methods: The study included 105 patients with soft tissue sarcomas admitted to the First Affiliated Hospital of Xinjiang Medical University between October 2009 and December 2012. The average age of the patients was 52 years old. Among the patients, 65 were males and 40 were females. Up to 82 patients underwent planned resection (Group A) in our hospital, and 23 underwent unplanned resection (Group B) in other hospitals. Wide excision and radical resection were conducted in Group A, whereas extended resection was performed in Group B. General data, tumor location and size, resection margin, local recurrence and metastasis, and survival were statistically analyzed in the two groups. Results:The proportion attaining the margin of wide excision was obviously lower in Group A than in Group B (P＜0.05). The 3-year survival rate was significantly higher in Group B than in Group A (P=0.001). Within an average follow-up of 18 months (3 months to 36 months) in Group B, 12 patients died, including 9 with tumor metastasis and 3 with other diseases. Within an average follow-up of 23 months (5 months to 36 months) in Group A, 15 patients died, including 12 with tumor metastasis and 3 with other diseases. Conclusion:Compared with planned surgical operation, unplanned resection of soft tissue sarcomas often leads to inadequate resection margin, which results in a high incidence of local recurrence and an increased mortality. Thus, clinicians should attempt to avoid unplanned resection of sarcomas.

Objective:To analyze the clinical effect of different surgical methods on giant-cell tumor of bone (GCTB). Methods:Between January 2007 and June 2012, 37 patients receiving treatment for GCTB were enrolled in this study. These patients included 20 males and 17 females whose ages ranged from 20 to 56 (average=31.6). The prosthesis replacement and nonprosthetic replacement op-eration on the postoperative recurrence, limb function, comprehensive evaluation of the curative effect, as well as morbidity and recur-rence rate among different nations and in the upper and lower limbs of GCTB patients were analyzed. Results:The predilection age of the cases ranged from 20 to 50 years old. The incidence was higher in the Uighur population of Xinjiang, China. However, the recur-rence rate in ethnic difference was not statistically significant (P>0.05). Conclusion:The predilection age of GCTB cases was 20~50 years old, with higher morbidity in Uighur than in Han and other ethnic groups. The morbidity and recurrence rate were higher in the lower limbs than in the upper limbs of patients. The scraping bone graft and bone cement filling, the internal fixation of the scraping bone graft, and the artificial joint replacement of tumor resection were all reliable modes of treatment.
