Multiple primary malignant neoplasm of the combination of the musculoskeletal system and the gastrointestinal system were very rare. A case of synchronous double primary malignant neoplasm consisted of myxofibrosarcoma of forearm and adenocarcinoma of rectum in a 52 year-old man was found. The patient had pain and swelling on forearm for 1 year. Histologically, the lesion on forearm showed myxofibrosarcoma. In systemic evaluation, the adenocarcinoma of rectum was found by the sigmoidoscopy, and metastasis on lung and intracardiac mass were found by the CT scan. We performed surgical excision and pre and postoperative chemotherapy after pathologic confirmation. He died of pulmonary thromboembolism after postoperative 2 months. We report this case of exceedingly rare combination of the musculoskeletal system and the gastrointestinal system.

Prostate cancer is a malignant tumor occurring in the prostate. Recently, the repetition rate is increasing. Image inspection method which we can check the prostate structure the most correctly is MRI(Magnetic Resonance Imaging), but it is hard to apply it to all the patients because of the cost. So, they use mostly TRUS(Transrectal Ultrasound) images acquired from prostate ultrasound inspection and which are cheap and easy to inspect the prostate in the process of treating and diagnosing the prostate cancer. Traditionally, in the hospital the doctors saw the TRUS images by their eyes and manually segmented the boundary between the prostate and nonprostate. But the manually segmenting process not only needed too much time but also had different boundaries according to the doctor. To cope the problems, some automatic segmentations of the prostate have been studied to generate the constant segmentation results and get the belief from patients. In this study, we propose an average shape model to segment the prostate boundary in TRUS prostate image. The method has 3 steps. First, it finds the probe using edge distribution. Next, it finds two straight lines connected with the probe. Finally it puts the shape model to the image using the position of the probe and straight lines.

Soy foods are a unique dietary source of isoflavones, which have effects relevant to prostate cancer prevention. The present study determines the effects of a short-term isoflavone supplement on serum PSA (prostate specific antigen), lipid profile, antioxidant status, and immune system in prostate cancer patients. Ten prostate cancer patients were supplemented daily with 150 mg of isoflavone for 2 months. Blood samples were collected baseline and 2 month after for analysis of PSA, serum lipid profiles, total antioxidant status (TAS), grade of DNA damage in lymphocytes, IL-6, VEGF and TNF -$\alpha$. After 2 month isoflavone supplementation, increased significantly a total of estimated urinary isoflavone excretion and did not change PSA. Serum lipid profiles showed significant change in serum total cholesterol level (p=0.007). However, there was no significant change in HDL- and LDL-cholesterol levels. TAS was increased but not significant after isoflavone supplementation. Tail moment (TM) was decreased and especially tail length (TL) was decreased significantly (p=0.043). IL-6 level was decreased but VEGF level and TNF -$\alpha$ level were increased. The results of the present study led to the conclusion that the isoflavone dosage (150 mg) in supplement had positive effects on the serum total cholesterol level and DNA damage.

Purpose: To conduct a nationwide academic hospital patterns of the practice status and principles of radiotherapy for prostate cancer. The survey will help develop the framework of a database of Korean in Patterns of Case Study. Materials and Methods: A questionnaire about radiation treatment status and principles was sent to radiation oncologists in charge of prostate cancer treatment at thirteen academic hospitals in Korea. The data was analyzed to find treatment principles among the radiation oncologists when treating prostate cancer. Results: The number of patients with prostate cancer and treated with radiation ranged from 60 to 150 per academic hospital in Seoul City and 10 to 15 outside of Seoul City in 2006. The primary diagnostic methods of prostate cancer included the ultrasound guided biopsy on 6 to 12 prostate sites(mean=9), followed by magnetic resonance imaging and a whole body bone scan. Internal and external immobilizations were used in 61.5% and 76.9%, respectively, with diverse radiation targets. Whole pelvis radiation therapy(dose ranging from 45.0 to 50.4 Gy) was performed in 76.9%, followed by the irradiation of seminal vesicles($54.0{\sim}73.8$ Gy) in 92.3%. The definitive radiotherapy doses were increased as a function of risk group, but the range of radiation doses was wide(60.0 to 78.5 Gy). Intensity modulated radiation therapy using doses greater than 70 Gy, were performed in 53.8% of academic hospitals. In addition, the simultaneous intra-factional boost(SIB) technique was used in three hospitals; however, the target volume and radiation dose were diverse. Radiation therapy to biochemical recurrence after a radical prostatectomy was performed in 84.6%; however, the radiation dose was variable and the radiation field ranged from whole pelvis to prostate bed. Conclusion: The results of this study suggest that a nationwide Korean Patterns of Care Study is necessary for the recommendation of radiation therapy guidelines of prostate cancer.

We analyzed the characteristics of the habitat environment for the Seonam study area in Ulsan, the southern shore of the East Sea using bathymetry and seafloor environment data. The depth of the study area ranges from about 0 m to 23 m. In the west of the study area, the water depth is shallow with a gentle slope, and the water depth becomes deeper with a steep slope in the east. Due to the right-lateral strike-slip faults located in the continental margin of the East Sea, the fracture surfaces of the seabed rocks are mainly in the N-S direction, which is similar to the direction of the strike faults. Three seafloor types (conglomeratic-grained sandy, coasre-graiend sandy, fine-grained sandy) and rocky bottom area have been classified according to the analyses of the bathymerty, seafloor image, and surface sediment data. The rocky bottom areas are mainly distributed around Seaoam and in the northern and southern coastal area. But the intermediate zone between Seonam and coastal area has no rocky bottom. This intermediate area is expected to have active sedimentation as seawater way. The sandy sediments are widely distributed throughout the study area. Underwater images and UAV images show that Cnidarians, Brachiopods, Mollusks are mostly dominant in the shallow habitat and various Nacellidae, Mytilidae live on the intertidal zone around Seonam. Annelida and Arthropod are dominant in the sandy sediments. The distribution of marine organism in the study area might be greatly influenced by the seafloor type, the composition and particle size distribution of the seafloor sediments. The analysis of habitat environment mapping with bathymetry, seafloor data and underwater images is supposed to contribute to the study of the structure and function of marine ecosystem.

Synchronous primary lung cancers in the same lobe are rare. Cavitating adenocarcinoma as single lung lesion is unusual. We experienced cavitating adenocarcinoma and squamous cell carcinoma in the same lobe of the lung. The patient was a 74-year-old male with chief complaints of hemoptysis. CT scan showd a central mass in right upper lobar bronchus, obstructive pneumonia, and lung abscess in the right upper lobe. Pathologically, the central mass was a 2.3$\times$1$\times$1 cm sized squamous cell carcinoma, and lung abscess was revealed as a 37272 cm sized adenocarcinoma. The patient was discharged without any specific problem after right peumonectomy.

Mucinous adenocarcinoma of the kidney is an extremely rare cystic malignant tumor with a poor prognosis that occurs in the pelvicalyceal system. Pre-opeartive diagnosis is very difficult because the tumor's clinical and imaging features are nonspecific. Here we report a case of primary mucinous adenocarcinoma arising from the horseshoe kidney in a 69-year-old male, focusing on CT findings. The tumor was a complex cystic mass with irregular wall thickening, multifocal calcifications, and septa and progressed to pseudomyxoma peritonei postoperatively.

Imaging studies play an important role in the detection, diagnosis, assessment of resectability, staging, and determination of patient-tailored treatment options for pancreatic adenocarcinoma. Recently, for patients diagnosed with borderline resectable or locally advanced pancreatic cancers, it is recommended to consider curative-intent surgery following neoadjuvant or palliative therapy, if possible. This review covers how to interpret imaging tests and what to consider when assessing resectability, diagnosing distant metastasis, and re-assessing the resectability of pancreatic cancer after neoadjuvant or palliative therapy.
