  • Anthocyanin from purple sweet potato (PSP) extracted by microwave baking (MB) and acidified electrolyzed water (AEW) exhibited antioxidant activity. After further purification by macroporous AB-8 resin, the color value of PSP anthocyanin (PSPA) reached 30.15 with a total flavonoid concentration of 932.5 mg/g. The purified extracts had more potent antioxidant activities than the crude extracts. After continuously administering the PSP extracts to 12-mo-old mice for 1 mo, the anti-aging index of the experimental group was not significantly different from that of 5-mo-old mice. To a certain degree, PSPA was also effective for controlling plasma glucose levels in male Streptozocin (STZ)-treated diabetic mice. In addition, the extracts inhibited Sarcoma S180 cell growth in ICR mice. Mice consuming the PSP extracts formed significantly fewer and smaller sarcomas than mice consuming the control diets. The highest inhibition rate was 69.03%. These results suggest that anthocyanin extracts from PSP not only exert strong antioxidant effects in vitro, but also had anti-aging, anti-hyperglycemic, and anti-tumor activities.

  • Synovial sarcoma is a malignant soft-tissue tumor that most commonly occurs in the extremities of young adults. There have been several cases of synovial sarcomas of the pleural and lung reported, but synovial sarcoma arising from the chest wall in childhood is very rare. Here we report a case of synovial sarcoma arising from the chest wall in a 3 year-old female patient. The tumor was completely resected. No adjuvant therapy was given. The patient is well 3 years after the operation.

  • Rhabdomyosarcoma is an uncommon type of soft tissue malignant neoplasm characterized by undifferentiated mesodermal tissue. Sarcomas account for approximately 1% of all laryngeal neoplasm and rhabdomyosarcomas are the rarest sarcoma found in the larynx. When the sarcoma involves the larynx, radical surgery such as laryngectomy has been considered. With recent advances of combined therapy, however, it can be treated by conservative surgeries followed by postoperative radiotherapy and/or pulse chemotherapy. With reviews of literature, we report a 47-year-old patient complaining of husky voice and throat discomfort who was finally diagnosed as rhabdomyosarcoma of the vocal fold and successfully treated by laser cordectomy followed by adjuvant chemoradiotherapy.

  • An 11-year-old spayed female maltese was presented for abdominal distention, dysuria and dyschezia. Panting and heart murmur was found and abdominal palpation was difficult due to increased abdominal pressure. A soft tissue mass, $6{\times}3cm$ in size, was identified radiographically in pelvic canal, displacing the descending colon to the medioventral direction and the urinary bladder cranially. On ultrasonography, the mass consisted of homogeneous hypoechoic parenchyma containing the focal hyperechoic region ($1.6{\times}1.5cm$). The mass had distinct margin and no connection with adjacent organs. It was considered as a mass originating from the retroperitoneal cavity. Additional diagnostic procedures were not advanced because of the owner's request, and only a surgical excision of the mass was performed to alleviate the dysuria and dyschezia. Histopathologic examination and immunohistochemistry determined the mass as a soft tissue sarcoma and excluded hemangiosarcoma and osteosarcoma, both are the most common types of the retroperitoneal tumors. This report described non-vascular soft tissue sarcoma originating from the retroperitoneal cavity in a maltese dog.

  • Primary pulmonary arterial sarcomas, especially those originating from the pulmonary valve are extremely rare. A 35 year-old male patient was admitted for exertional dyspnea and fatigue. Large intraluminal mass in the main pulmonary artery and both pulmonary arteries was detected by chest computed tomogram, chest magnetic resonance imaging, echocardiogram, and pulmonary angiogram. We regarded the mass as a primary pulmonary arterial malignant tumor, and resected under cardiopulmonary bypass. The mass was appeared to originate from the posterior cusp of pulmonary valve, and extended from below pulmonary valve to main pulmonary artery and both pulmonary arteries. We resected the mass by pulmonary endarterectomy and replaced the pulmonary valve. The mass was diagnosed as a pulmonary arterial sarcoma in histopathologic examination.

  • Background: This is a part of a larger effort to characterize the effects on socio-economic factors (SEFs) on cancer outcome. Surveillance, Epidemiology and End Result (SEER) bone and joint sarcoma (BJS) data were used to identify potential disparities in cause specific survival (CSS). Materials and Methods: This study analyzed SEFs in conjunction with biologic and treatment factors. Absolute BJS specific risks were calculated and the areas under the receiver operating characteristic (ROC) curve were computed for predictors. Actuarial survival analysis was performed with Kaplan-Meier method. Kolmogorov-Smirnov's 2-sample test was used to for comparing two survival curves. Cox proportional hazard model was used for multivariate analysis. Results: There were 13501 patients diagnosed BJS from 1973 to 2009. The mean follow up time (SD) was 75.6 (90.1) months. Staging was the highest predictive factor of outcome (ROC area of 0.68). SEER stage, histology, primary site and sex were highly significant pre-treatment predictors of CSS. Under multivariate analysis, patients living in low income neighborhoods and rural areas had a 2% and 5% disadvantage in cause specific survival respectively. Conclusions: This study has found 2-5% decrement of CSS of BJS due to SEFs. These data may be used to generate testable hypothesis for future clinical trials to eliminate BJS outcome disparities.

  • Myxofibrosarcoma, also known as a myxoid variant of a malignant fibrous histiocytoma (MFH), is one of the most common sarcomas in the extremities of elderly people. The lesion is characterized by a high frequency of local recurrence but is uncommon in the head and neck regions. Low-grade myxofibrosarcoma, which is commonly misinterpreted as being benign, has a tendency for histological and biological progression in local recurrences, highlighting the importance of an accurate diagnosis and wide surgical excision of the primary lesion. We report a rare case of low-grade myxofibrosarcoma of the mandible located in the left mandibular body and angle area. The tumor was first diagnosed as a myxofibroma and was resected initially. After the final biopsy the patient underwent combined chemo-radiotherapy. The progress of the patent was uneventful until the one year follow up.

  • Primary central nervous system (CNS) sarcomas are exceedingly rare, and, to the best of our knowledge, there has not yet been a report of intramedullary sarcoma. Here, we report a primary intradural intramedullary sarcoma of the spinal cord in a four-year-old boy who presented with low back pain and a radiculopathy involving both lower extremities. The tumor showed significant enhancement on magnetic resonance (MR) images due to its extreme vascularity. Gross total tumor removal was performed with microelectrical pulse recording, and the patient also received adjuvant radiotherapy and chemotherapy. After the operation, the patient's sensory deficits were improved. Because CNS dissemination is common, entire neuraxis evaluation is essential, although there was no evidence of dissemination in this case. The prognosis of primary CNS sarcoma is poor due to infiltrative nature and early CNS dissemination is common, and the treatment of choice is radical surgical resection. Adjuvant therapy is also beneficial with radiotherapy and chemotherapy.

  • Primary malignant bone tumors of the scapula are very rare, and little literature is available regarding their characteristics and outcome. We studied the clinical characteristics, and outcome of patients with primary malignant bone tumors of the scapula. From 1979 to 2008, we treated 7 patients at our institute (4 men and 3 women; chondrosarcoma 3, Ewing's sarcomas 3, Osteosarcoma 1). The mean age was 45 years (range, 5~65 years). The follow-up period was 2 - 180 months. Six patients were performed operations: total scapulectomy 3, partial scapulectomy 1, forequarter resection 1, total resection of the shoulder girdle (Tikhoff-Linberg procedure) 1. No-operative treatment was chosen for one patient with a limited life expectancy. Local recurrence occurred in one patient. Distant metastasis occurred in 3 patients. Of the 7 patients, 4 patients are died because of propagation of the disease. Three patients were alive and apparently disease-free, and these patients were evaluated for functional results with the functional evaluation system of the International Society of Limb Salvage (ISOLAS). Functional result of partial scapulectomy was excellent, however, the function after total scapulectomy or Tikhoff-Linberg procedure is severely impaired. Our study indicates reconstruction procedure needs to be reconsidered following total scapulectomy or Tikhoff-Linberg procedure.

  • A case of a 39-year-old man with granulocytic sarcoma documented by positive Ga-67 scan is described and brief review of literature was performed. He was diagnosed as acute myelogenous leukemia and got complete remission with antileukemic chemotherapy for 7 months. On admission, picture of his bone marrow and peripheral blood showed remission state of leukemia. Radiologic examinations were performed for evaluation of lesions in head and chest, and findings of granulocytic sarcoma were suspected. So we got $^{67}Ga-citrate$ scan and pleural biopsy for identification of causes of intractable pleural effusion and skin lesion. Myeloblastomas (or granular sarcomas) proved by pleural biopsy were correctly identified by $^{67}Ga-citrate$ scan, and disease extent was clearly delineated. We believe that $^{67}Ga-scintigraphy$ is very helpful in localizing and follow-up evaluation of granulocytic sarcoma.
