Mesenchymal to epithelial transition (MET), whereby mesenchymal cells become more epithelial like in phenotype, was observed to occur during normal development and in cancers. Numerous investigations have been conducted on MET in carcino-mas. In addition, accumulating evidence also suggests the critical function of MET in sarcomas. Integrated analyses reveal that MET may be an important biological and clinical process in sarcomas, and transcription factors such as Slug may also perform central func-tions in epithelial differentiation in several sarcomas such as leiomyo-sarcoma and synovial sarcoma. Given the scarcity of investiga-tions and evidence, several important issues about MET, such as its molecular markers, signaling mechanisms, micro RNA regulations, and clinical significance, need to be clarified. In this article, we review several important questions about MET in sarcomas, including molecular markers, signaling mechanisms, regulation by miRNAs, and therapeutic implications.

Objective To performed microarray-based comparative genomic hybridization (aCGH) detection and carried out pathway analysis to gain a systemic view on the pathway alterations of the genetically altered genes in human osteosarcoma.Methods aCGH experiments were carried on 10 fresh osteosarcoma samples to obtain recurrent copy number change pattern,then the samples were further subjected to the Kyoto Encyclopedia of Genes and Genomes (KEGG) pathway analysis to identify the altered pathways in the osteosarcoma.To validate the aberrations of these key pathways,the alterations of VEGF pathway were selected to confirm by the methods of fluorescence in situ hybridization (FISH) and immunohistochemistry (IHC) in formalin-fixed and paraffin-embedded (FFPE) osteosarcoma archival tissues.Results The KEEG analysis of aCGH data identified 33 genetically altered pathways in osteosarcomas.Among them 20 pathways were identified genetic amplifications,such as VEGF and mTOR signaling pathways.Thirteen pathways were genetic deletions,such as Wnt and Hedgehog signaling pathways.The genetic aberrations of cell-cell-matrix pathway such as CAMs,Adherens junction and Tight junction pathways implied the genetically alterations of these pathways which are associated with the tumor invasion and metastasis.Validation the aberrations of VEGF pathway showed that VEGFA gene was significantly amplified.The positive protein expression of VEGFA had a significant association with microvessel density (MVD).Conclusion There are genetic aberrations which involved the component genes of VEGF,mTOR,CAMs,Adherens junction,Wnt,Hedgehog and other 26 signaling pathways.The alterations of these pathways which are significantly associated with tumor invasion,metastasis and progression suggest that the genetic aberrations of these key pathways might contribute to the tumorigenesis and progression in human osteosarcoma,and provide molecular genetic evidence for targeted therapy.

Objective:To investigate the safety and efficacy of laminectomy combined with vertebroplasty in spinal metastases from rapid-growth tumors. Methods:Clinical data of 23 patients with spinal metastases of lung cancer, who were admitted to the Cancer Hospital from July 2008 to May 2012, were retrospectively analyzed. Thirteen male and ten female patients, with an age range from 40 years to 65 years and a mean age of 51.5, were examined. All patients received posterior laminectomy to relieve spinal cord compression. Afterward, vertebroplasty combined with radiofrequency ablation was conducted, followed by the internal fixation of vertebrae (instrumental fixation). Operation time, blood loss, and bone cement leakage rate were analyzed. One month before and after the operation, pain measurement was conducted using visual analog scale (VAS) and neurologic deficit (spinal cord injury) by Frankel Grade. Functional impairment was classified by Karnofsky performance status (KPS) score. Quality of life was assessed by the European Organization for Research and Treatment questionnaire (EORTC QLQ-C30). Results:The mean operation time was 163±87.36 min. Blood boss was 430±130.35 mL. Bone cement leakage rate was 21.7%. One month before and after surgery, the VAS showed statistical significance (t=25.6, P<0.01). After surgery, 78.3%of all patients exhibited functionally satisfactory Frankel Grade D or E, compared with 43.5%of patients before the operation. KPS score (80 to 100) percentage was 69.6%after surgery compared with 34.8%before surgery. One month after the operation, remission of various degrees was seen in 10 of 18 patients who had sphincteric dysfunction before surgery (55.6%). The EORTC QLQ-C30 score was 85.39±8.99 before and 52.78±15.17 after operation. The quality of life improved significantly (t=11.6, P<0.01). Conclusion:Posterior laminectomy and vertebroplasty combined with radiofrequency ablation for spinal metastases from lung cancer is safe and effective. The treatment can improve pain, function, and life quality of patients with lung cancer spinal metastases.

ObjectiveTo investigate the safety and efficacy of combined treatment with subtotal corpectomy and radiofrequency ablation(RFA) for spinal metastases. MethodsFrom April 2009 to March 2010, 29 patients with spinal metastases who received subtotal corpectomy were analyzed. Sixteen patients (7 men and 9 women) with an average of 57.8 years having received subtotal corpectomy alone were selected for comparison (the subtotal corpectomy group). Thirteen patients (7 men and 6 women) with an average of 58.3 years having received subtotal corpectomy combined with RFA were chosen as subjects of this study (the RFA combination group). There were no significant differences between the two groups with respect to the patient's age, gender, and Tomita type. Pain levels pre-and post-procedure were assessed by the visual analogue scale(VAS), and neurologic deficit were evaluated by the Frankel scale. ResultsThe VAS in RFA combination group were 8.88±0.36, 3.76±0.33, 3.35±0.38 in preoperation, 1 month, and 6 months postoperatively, respectively. The VAS in subtotal corpectomy group were 8.96±0.39, 3.81 ±0.48, 3.41 ±0.42 in preoperation, 1 month, and 6 months postoperatively, respectively. The VAS in both groups showed statistical significance at each time point, there was no statistically difference between the two groups. The operate time in RFA combination group and subtotal corpectomy group were(216.54±113.77) min and(302.50±80.44)min, respectively. The blood loss of the two groups were (1084.62±539.82)ml and (1625.00±724.34)ml, respectively. The recurrent rate of the two groups were 30.8% and 75.0%, respectively. The RFA combination group were lower in operate time, blood loss and recurrent rates than subtotal corpectomy group. Conclusion Compared with the subtotal corpectomy, the RFA combination can reduce the blood loss, operation time, and the recurrent rates.
