  • Synovial sarcoma is an uncommon malignant soft tissue tumor which usually occurs in young-aged person, and frequently involves the lower extremities. Many authors recommended wide excision, adjuvant chemotherapy and radiation therapy. The proposed factors that affect the prognosis are age, size of tumor, site of tumor in the body, depth of tumor, histologic grade and method of treatment. The purpose of the study is to analyze the factors that affect the 5-year survival rate. We retrospectively evaluated 19 cases of synovial sarcoma treated in the Kosin University Medical Center from Jan. 1982 to Dec. 1994. The overall 5-year survival rate was 47.6% and the 5-year survival rates were significantly higher(P<0.05) in the group with smaller size of mass. The significantly lower 5-year survival rates were observed in the patient with deeply located lesion and with higher histologic grade. The 5-year survival rates were higher in the patients treated with wide excision than in the patients treated with amputation. But there was no significant difference between these groups. The adjuvant chemotherapy and radiotherapy were performed. In conclusion, we suggest that the better prognosis will be observed in the patients with smaller size of tumor mass, superficially located and lower histologic grade.

  • Desmoid tumor is found most often in the anterior abdominal wall of parous women. Although it may originate in virtually any musculotendinous structure, those of the chest wall are rare. We experienced a case of large dumb bell shaped desmoid tumor originated in intercostal muscle and invaded anterior chest wall, pericardium, pleura and the lung. The patient was healthy in appearance except a painful swelling on the anterior chest wall. Roentgenographic studies demonstrated a huge homogenous mass in the right anterior chest cavity. He was treated with resection of the tumor including .anterior chest wall, a portion of the pericardium, middle lobe, and part of upper & lower lobes of the right lung because of tumor invasion. The tumor composed with two parts, one [$5{\times}4{\times}3$cm in size] is over the rib cage and another [$10{\times}15{\times}10$cm in size] is in the right chest cavity. Postoperative course was uneventful and there was no evidence of recurrence until last visit, 5 months after surgery.

  • Study purposes were to evaluate ultrasonographic characteristics of transitional cell carcinoma (TCC) and quantitate bladder tumor size in dogs. Heterogeneous mass, wall involvement, and broad-based attachment were significantly associated with TCC, but not prominently the trigone region. Mass size evaluation revealed a significant correlation between progressive disease (PD) in TCC patients with piroxicam therapy. Largest diameter of target lesion/body weight (cm/kg) ratio showed a high mean value in PD. A value > 0.3 was associated with PD with 83% sensitivity and 66% specificity. The results suggest that ultrasonography can provide evidence for diagnosing and predicting a prognosis for TCC.

  • Purpose: Malignant peripheral nerve sheath tumor without neurofibromatosis type 1 is very rare neoplasm. Development in the superficial soft tissue is exremely rare. Authors experienced one rare case of primary malignant peripheral nerve sheath tumor developed on abdomen. The clinical and histologic findings were described. Methods: An 83-year-old man visited hospital with an $11{\times}6.5{\times}4.5$ cm sized ulcerated and hemorrhagic mass on abdomen. The tumor was localized in abdominal skin and started growing 3 years ago. Results: Wide excision with safety margin of 2 cm and limberg flap was done. The postoperative biopsy revealed a malignant peripheral nerve sheath tumor. There was no evidence of recurrence of tumor for 16 months. Conclusion: Malignant peripheral nerve sheath tumor is an aggressive malignant tumor. An abrupt enlargement of size, ulceration and bleeding are suggestive of malignant chnages of the tumor. We recommand early wide excision with enough safety margin as treatment of malignant peripheral nerve sheath tumor.

  • A 12-year-old, 8.0 kg, spayed female, mixed-breed dog was presented to the Veterinary Medical Teaching Hospital of Chungnam National University (VMTH, CNU). That case has been growing up mass in her left upper hindlimb about for 2 years and has showed vomiting and anorexia for 3 days. The patient was diagnosed with mast cell tumor on the basis of fine-needle aspiration (FNA) cytology techniques. According to World Health Organization clinical staging system for diagnosing mast cell tumors, it was classified into stage IIIa. The patient was treated by adjuvant corticosteroid therapy, but complete surgical excision was not achieved by owner's request. In the early stage of therapy, the size of the mass was gradually reduced with only adjuvant glucocorticoid therapy, so the patient's general condition was maintained well. But after 53 days later, the treatmant was not effective anymore and mass size was increased. Two months later, she was euthanized because of intermittent vomiting and severe respiratory distress. Splenic mass, duodenal ulceration, liver mass and infiltrated mast cell tumor in upper hindlimb muscle region were found in necropsy examination.

  • Many different factors which may affect the prognosis of the soft tissue sarcomas have been reported by many authors ; Generally, tumor size, histologic type, surgical margin, and multi modality therapy therapy as the prognostic factors were reported. The objectives of this retrospective study of soft tissue sarcomas are : 1) to define more clearly prognostic variables that have significant predictive value for disease-free and overall survival ; and 2) to evaluate tumor histologic grade based upon extent of tumor necrosis as a means of stratifying more aggressive soft tissue sarcomas(grade II & III) of the extremities. We treated 94 patients who had soft tissue sarcoma of the extremities and trunk from May 1984 to September 1994(average duration of follow-up was 5 years ranging from 2 months to 10 years) and evaluated the prognostic factors of the soft tissue sarcomas; age, sex, depth, size, location, histologic type and grade, stage, therapy modality, surgical margin, local recurrence and distant metastasis. The results were as follows. 1. The patients with poorer prognosis were over the age of fifty, whose mass was deeply located, size of the mass was over 10cm in diameter, grade III in histology, who had local recurrence, metastasis, and received only surgery. 2. Among these prognostic factors, the most significant prognostic factor was histologic grade base upon extent of tumor necrosis.

  • In this paper, we present a new method for the detection of spiculation on digital mammograms. Traditional methods have defects; sensitive to noise, fixed size processing, and long processing time, however, the proposed method has merits; not sensitive to noise, adaptive size processing, and fast processing time. Experimental results show that the spiculation detection performance of the proposed method is improved much compared to the other methods.

  • This is a clinical analysis of 24 cases of parotid gland tumor who were treated in the department of Surgery, Chonnam National University Medical School during the past 10years from January, 1976 to December, 1985. According to this analysis of total 24 cases, we concluded as follows; 1) 21 cases were benign tumors and 3 cases were malignant tumors. As the histopathological findings, benign tumor included 88%and malignant tumor 12%. Majority of benign tumor contained mixed tumor(86.7%), and the malignant tumor contained mucoepidermoid carcinoma (66.7%). 2) The peak age incidence was 40th in benign tumor and 50th in malignant tumor. 3) The chief complaints of patient was a painless mass and the duration of illness was average 5.2 years. 4) The mean size of mass was 4.5cm in diameter. 5) The surgical procedures were performed with excision 6 cases, superficial lobectomy 8 cases, wide excision with partial parotidectomy 4 cases, total parotidectomy 3 cases in benign tumors. In malignant tumors, total parotidectomy 2 cases and wide excision with partial parotidectomy 1 case were performed. 6) Major postoperative complications such as facial nerve palsy 7 cases (temporary ; 5 cases, permanent; 2 cases), Frey syndrome 1 case, seroma 1 case, hematoma 1 case, and wound infection 1 case were developed. The recurrence contained pleomorphic adenoma 1 case and mucoepidermoid carcinoma 1 case.

  • Background: Metabolic syndrome (MetS) is a multifactorial disease characterized by impaired glucose tolerance/diabetes, obesity, high triglyceride levels, low HDL levels, and hypertension. In this study we evaluate the relationship between tumor size and grade, and presence of the metabolic syndrome in patients with renal cell carcinoma. Materials and Methods: Between 2007-2013, radical nephrectomy was performed for 310 patients with renal tumors in our clinic and those with pathology reported renal cell carcinoma were enrolled and divided into two groups, with and without metabolic syndrome diagnosed on the basis of the National Cholesterol Education Program (NCEP) Adult Treatment Panel III (ATP III) criteria. The relationship between tumor size and grade of the two groups (Fuhrman nuclear degree) was evaluated statistically. Results: The metabolic syndrome was found in 70 patients, with a mean age of 65.5 (40-87), as compared to 58.8 (31-84) years in the non-metabolic syndrome group. Tumor size over 7 cm was found in 54% and 33%, respectively, and tumor grade over Fuhrman 3 in 56% and 32% of patients. Patients with metabolic syndrome had significantly higher tumor size and grade (p<0.05). In the presence of hypertension, diabetes and high triglyceride levels, significant assocations were again observed (p<0.05). Tumor size and degree also increased with increasing body mass index but this was not statistically significant (p>0.05). Conclusions: Renal cancer is more aggressive in patients with metabolic syndrome. Lifestyle and risk factors were revealed to be significant influences in renal cancer patients.
