A giant cell tumor of bone is a benign bone tumor, but has very high local recurrence rate and, very rarely metastasizes to the lung or a distant area. We report a case of a 29-year-old male patient presenting with a metastatic giant cell tumor of the soft tissue of the chest wall, who underwent a total resection of the radius for recurrence of the giant cell tumor. The tumor was not related to any bony structure of the thorax. We resected the tumor with a wide surgical margin. No evidence of malignancy was seen in the frozen and permanent pathological report.

Spindle epithelial tumor with thymus-like differentiation (SETTLE) is an extremely rare type of thyroid tumor, with spares reports on its clinical course. SETTLE is derived from branchial pouch or thymic remnants, and classified as a low grade, malignant neoplasm due to its indolent growth and tendency to develop delayed metastasis. Therefore, stringent initial workups and long-term follow-up are required to prevent misdiagnosis. We present a case of recurrent spindle epithelial tumor with thymus-like differentiation (SETTLE) in the glottis of 57 year-old male patient, who had a history of surgical excision for the SETTLE from the thyroid gland 5 years ago. Transoral CO2 laser surgery was performed to remove the glottic tumor and there was no evidence of local recurrence at 11 months postoperatively.

Surgical treatment of pelvic bone tumors represent one of the most complicated problem in musculoskeletal oncology. Because of three dimensional anatomy of the pelvis, tumors reach huge sizes and the diagnosed late relatively to a similar tumors in extremity. Especially, there are limited reconstruction methods to keep the function of hip joint after resection of periacetabular tumors, and the results of reconstruction is not so promissing. We present one case of periacetabular metastatic tumor from renal cell carcinoma, which was resected with wide margin and reconstructed with composite of pasteurized autogenous bone graft and constrained total hip arthroplasty.

A sex cord tumor with annnular tubules is a relatively rare ovarian neoplasm. The cytologic findings from a fine needle aspiration biopsy of neck metastasis of a sex cord tumor with annnular tubules are described. The origin of the neck metastasis was the right ovary, and the tumor was diagnosed six years ago. The cytologic findings were characterized by tumor cells arranged in solid or follicular patterns. The tumor cells formed rosette-like or complex tubular structures with central rounded or coalesced hyaline materials. It was difficult to distinguish this tumor cytologically from granulosa cell tumor, thyroid follicular neoplasm, Sertoli-Leydig cell tumor, and Brenner tumor, but complex tubular structures were helpful in discriminating between these tumors.

Purpose: In this report we are going to discuss about the functional evaluation and the outcome of treatment of metastatic tumor in the lower extremities treated with tumor prosthetic arthroplasty. Materials and Methods: This report is based on nine patients diagnosed as a metastatic tumor and treated by tumor prosthetic arthroplasty, from June 1998 to December 2001. Age of the patients ranged from 49 to 63 with the average of 56.3. The average follow up period was 23.4 months. Two patients had lung cancer, three had breast cancer, two had renal cancer, one colon cancer, and one had multiple myeloma. All these were primary cancers. The site of metastasis were six in proximal femur, two in distal femur, and one in proximal tibia. Tumor excision was performed after biopsy in following the principle of primary tumor management. Excision with wide surgical margin was tried as possible could. Six cases were treated with tumor prosthesis, and the other three cases were reconstructed with bone cement and arthroplasty. Results: The functional evaluation in the extremities at the last follow up was performed on Enneking evaluation score with 6 categories. The highest scored 26, and the lowest scored 10, with an average of 19.5. A case in which the patient died 15 days after the operation was excluded from the evaluation. Among the categories, emotional acceptance to postoperative function and pain relief were highly scored. At the final follow up, seven patients survived, and one colon cancer patient died 68 days after operation. Conclusion: Metastatic tumor occurring in joints of lower extremities could be treated in accordance to the treatment principle of primary tumor. By insertion of tumor prosthesis, we can get satisfactory results of function in the lower extremity and pain relief especially. So, this aspect of medical favor must be considered in treating patients.

The present study was carried out to investigate the antitumor activity of Salvia miltiorrhiza (SM) herbal extract in rat tumor model. We used a new tumor animal model for the invasion and metastasis of cancer using genetically k-ras-induced rat kidney cells (RK3E-ras). We observed tumor as early as 7 days after the injection of RK3E-ras cells in subcutaneous of Sprague-Dawley rats. All of the rats developed tumor mass at the inoculated site. After 7 days, the experimental groups were divided into two: saline control and injected with SM (200 mg/kg) groups. We investigated tumor's weight, size and hepatic metastasis of each group. Injection of SM herbal extract every other day for 14 days significantly inhibited tumor growth. Histologically, the tumors were undifferentiated carcinoma showing multifactorial necrosis and hemorrhage; also, the tumor invaded into hepatoportal region. Treatment with SM herbal extract caused significant inhibition of tumor cell proliferation. Our data showed that SM herbal extract is effective in controlling the tendency of tumor cell proliferation and metastasis by injection of RK3E-ras cells. These findings provided the potential value of SM as a novel antitumor agent candidate.

Purpose: It has been previously reported that breast tumor incidence, growth, and metastasis are stimulated by high-fat diet but reduced by caloric restriction. However, few studies have elucidated the effects of dietary change from a high-fat diet after breast cancer initiation. Therefore, in this study, we attempted to provide practical assistance to breast cancer prevention and management by investigating the effects of dietary change from a high-fat diet to normal diet on breast cancer growth and metastasis. Methods: The experimental animals were divided into 2 groups (high-fat diet control [HFC] group and diet restriction [DR] group) and consumed a high-fat diet for 8 weeks. 4T1 cells were transplanted into subcutaneous fat or tail vein to measure the growth and metastasis of breast cancer. The HFC and DR groups continuously ingested either high-fat diet or AIG-93G diet for 5 weeks or 3 weeks, respectively. Cell proliferation and apoptosis markers from tumor tissues were analyzed by Western blot analysis. The data were analyzed using the SPSS 25.0 package program. Results: The results show that the DR group significantly reduced breast tumor initiation, growth, and tumor tissue weight compared to the HFC group. The DR group suppressed tumor growth by decreasing proliferation and inducing apoptosis through down-regulation of Bcl-xL and up-regulation of caspase-3 activity. Furthermore, the DR group significantly reduced numbers of metastasized tumors in lung tissues. Conclusion: These results suggest that dietary change from a high-fat diet to normal diet decreased breast growth by reducing cell proliferation and inducing apoptosis and metastasis. Taken together, these results indicate that dietary change to a low-fat and balanced diet might suppress breast tumor growth and metastasis even after tumor diagnosis.

Introduction: Currently, F-18 fluorodeoxyglucose positron emission tomography scans (FDG-PET) has been investigated in soft tissue tumor especially for tumor detection and noninvasive grading. However, the validity and the efficacy of FDG-PET are still unclear in clinical evaluation. The purpose of this study is to determine the efficacy of FDG-PET in compared to conventional diagnostic imaging studies currently used in the soft tissue tumor. Methods: Between March 2001 and March 2002, 29 patients (sixteen males, thirteen females, mean age, 47 years; a range from 4 to 73) diagnosed with soft tissue tumor were evaluated by both conventional diagnostic imaging and FDG-PET. Valid reference test of the local lesion was the histopathologic diagnosis, which was measured in all patients. The suspecting metastasis in the imaging studies was validated by pathology or follow up imaging for at least 6 months. Each imaging diagnosis was made independently. The accuracy of each diagnostic method was evaluated. The incremental cost accuracy ratio was determined in each diagnostic method. Results: For detection of local lesion, sensitivity, specificity, and accuracy for MRI and FDGPET scans were 91%, 57%, 83% and 95%, 43%, 83% respectively. For detection of distant lesion, sensitivity, specificity, accuracy for conventional diagnostic methods and FDG-PET scans were 77%, 89%, 87% and 92%, 94%, 93% respectively. The incremental cost accuracy ratio (ICAR) of FDG-PET for detection of distant lesion was 145,000won/%. According to ICAR for each tumor grade, PET strategy is most cost-effective at high grade tumors. Conclusions: For detection of local lesion such as recurrence or remnant tumor, FDG-PET scan was not more accurate than MRI. However, It was more accurate for detection of metastatic lesion than conventional methods. For detection of high grade tumor, PET was most costeffective than for detection of lower grade tumor.
