Treatment of Ⅰ~Ⅱgrade giant cell tumors of bone with open cryosurgery: light and electron microscopic observation and long-term effect[J]. Journal of Chongqing Medical University, 2000,(2):190-191. DOI: 10.13406/j.cnki.cyxb.2000.02.031.
Objective:To study the role of cryotherapy in decreasing the five-year recurrence rate of giant cell tumor of bone treated with curettage and bone grafting. Methods:Curettage plus open cryotherapy was carried out on 8 cases of Ⅰ~Ⅱ grade giant cell tumor of bone and the frozen specimens of 5 cases were observed with light and electron microscope. Results:All patients
followed postoperatively for an average of 10.8 years
were surviving. It was proved by light and electron microscopic observation that the tumor cells were completely destroyed after freeze-thaw more than 3 times. Conclusion:After curettage
there are some living tumor cells remaining on the wall of residual cavity and Cryotherapy can destroy the residual tumor cells existing within 2cm thickness of the wall of cavity. Cryotherapy can effectively decrease the postoperative recurrence.
