..We undertook this study to assess the therapeutic results of superficial soft tissue sarcomas as related to the presence of microscopic invasion, and to identify prognostic factors so as to optimize the therapeutic strategy...

..In the long postoperative follow-up of 6 years, the course has been both oncologically and functionally favorable. Therefore, this reconstruction technique can be considered as a good treatment option...

..The aim of this study was to better clarify the necessity for adjuvant therapy and the width of the resected margin, by investigating the clinicopathological results of T1 (?5 cm) soft tissue sarcomas...

..We determined the diagnostic accuracy rate of 207 cases that underwent CT-guided needle biopsy for musculoskeletal lesions during the past 10 years, and describe the efficacy and indications of this method...

..The main purpose of this study was to evaluate the clinical outcomes for patients with chest wall soft tissue sarcomas...

..The aim of this study was to investigate the necessity for venous reconstruction by comparing the results of arterial reconstruction alone and those of arteriovenous reconstruction...

....

..The clavicula pro humero reconstruction is a useful procedure that could reduce the occurrence of complications, especially in young patients and in patients with involvement of the nondominant arm...

..Inappropriate (unplanned) excisions may adversely affect local recurrence, distant metastasis, patient survival, and /or postoperative function once properly evaluated...

..Whether "pure" tumors without round cells are low grade has not been confirmed. While radiotherapy has been used for patients' myxoid liposarcoma it is unclear whether it reduces local recurrences...

..Clavicula pro humero reconstruction should be considered in selected patients for whom acromio-clavicular joint could be preserved after extensive resection of humerus or glenoid to obtain wide surgical margin...

..In group I patients, high-grade malignancy, adjuvant chemotherapy, and deep location were poor oncologic factors, and deep location and prereferral surgery were adverse prognostic factors for functional score...

..The objective of this study was to identify the MRI criteria that best differentiate malignant peripheral nerve sheath tumors from benign neurofibromas...

..To evaluate the efficacy, post-treatment function, toxicity, and complications of carbon ion radiotherapy (RT) for sacral chordoma compared with surgery...

..These observations suggest that versican expression may serve as a marker of tumor grade determination in chondrosarcoma and possibly help to decide on therapeutic targets in higher grades of chondrosarcoma...

..This study demonstrated that pasteurized autogenous bone graft remained structurally stable for many years, although facilitators such as the combined use of a vascularized fibula are required to promote regeneration of the graft...

..Sentinel lymph node biopsy with conventional blue dye alone might be insufficient to assess lymph node status in patients with recurrent rhabdomyosarcoma previously treated with surgery and/or radiotherapy...

..The aim of our study was to clarify the occurrence of osteochondral destruction according to the location of PVNS during the clinical course...

..These data support the contention that the residual thickness of subchondral bone could be a factor predicting the location of recurrence, and operative procedure to avoid re-operation might be critical to preserve knee function...

..Levels of VEGF protein expression serve as a novel diagnostic and prognostic tools for peripheral nerve sheath tumors...

..Needle biopsy seems useful in the sense that it can distinguish between tuberculous lesions in cases of spinal infection. In patients with a primary bone tumor, application of needle biopsy should be subjected to further consideration...

..A wide resection seems suitable for most granular cell tumors in the extremities. Level of Evidence: Level IV, diagnostic study. See the Guidelines for Authors for a complete description of evidence...

..Few studies have described the characteristics and prognostic factors of osteosarcoma patients aged over 60 years...

..Although hemarthrosis of GT is rare, this disease should be considered in a patient with bleeding tendency and prolonged bleeding time...

..The masses of 2 patients were excised due to rapid growth. Both of these patients had no recurrence. The other 2 patients were followed without surgical excision, and the masses partially regressed without functional impairment...

..Nine years after the onset of the patient's complaints of knee pain and swelling, the tumor was adequately diagnosed on physical examination and MRI, and was resected with complete relief of symptoms...

..We report 2 cases of males with an isolated brachialis muscle tear who were referred to our hospital with a diagnosis of a neoplasm in the arm. Both of the patients improved completely without radical treatment...

..This procedure is a useful, safe method owing to its minimal invasiveness in patients with unstable pelvic fractures that are reducible by manual manipulation or traction...

..Although all isosulfan blue-stained groin lymph nodes were negative for malignancy, a popliteal lymph node was positive. Adjuvant 50 Gy of radiotherapy to the popliteal node might have been effective for local control for one year...

..Although reconstruction of the pelvic ring was not performed, his ambulatory function had recovered to an almost normal status at 6 months after the operation...

..The DNA index correlated with MTR in such musculoskeletal tumors ( P < 0.05). This suggests that MTR can be used as a parameter to quantitatively indicate malignancy...
