From Jan. of 1990 to Dec. of 1992, we have experienced three cases of multiple primary malignant neoplasms originated from different histogenesis, in the Department of Orthopedic Surgery of Korea Cancer Center Hospital. Liposarcomas, malignant fibrous histiocytoma were combined with renal cell carcinoma, mucinous cystadenocarcinoma of ovary or prostatic cancer. With Moertel's classification, synchronous tumors were found in 2 cases and metachronous in 1 case. Synchronous tumors were 2 liposarcomas-renal cell carcinoma or mucinous cystadenocarcinoma of ovary. Metachronous tumors were malignant fibrous histiocytoma-prostate cancer. We couldn t find any family history among them. The causes of these multiple malignancies were considered as the individual predilrection to tumors.

Calcific tendinitis usually occurs in the supraspinatus tendon of the shoulder. Calcific tendinitis of the peroneus longus tendon has not been reported on the Korean journals. Differential diagnosis includes bipartitis os peroneum, os peroneum fracture and peroneal tendinitis. We report a rare case of calcific tendinitis of the peroneus longus tendon which responded well with the conservative treatment.

BACKGROUND: To decide the optimal antibiotics and application of chest tube, examination of pleural fluid is fundamental in the management of empyema. Some criteria for drainage of pleural fluid have been recommended but some controversies have been suggested. Recently, newer radiologic methods including ultrasound and computed tomography scanning, have been applied to the diagnosis and management of pleural effusions. We undertook a retrospective analysis of 30 patients with pleural effusion who had CT scans of the chest in order to apply the criteria of Light et at retrospectively to patients with loculation and to correlate the radiologic appearance of pleural effusions with pleural fluid chemistry. METHOD: We analyzed the records of 30 out of 147 patients with pleural effusion undergoing chest CT scans. RESULTS: 1) Six of the pleural fluid cultures yielded gram negative organisms and three anaerobic bacterias and one Staphylococcus aureus and one non-hemolytic Streptococci. No organism was cultured in nineteen cases(63.0%). 2) The reasons for taking chest CT scans were to rule out malignancy or parenchymal lung disease(46.7%), Poor response to antibiotics(40.0%), hard to aspirate pleural fluid(10.0%) and to decide the site for chest tube insertion(3.3%). 3) There was no significant correlations between ATS stages and loculation but there was a tendency to Inoculate in stage III. 4) There was a significant inverse relationship between the level of pH and loculation(P<0.05) but there appeared to be no relationship between pleural fluid, LDH, glucose, protein, loculation and pleural thickening. 5) In 12 out of 30, therapeutic measures were changed according to the chest CT scan findings. CONCLUSION: We were unable to identify any correlations between the plerual fluid chemistry, ATS stages and loculations except pH, and we suggest that tube thoracotomy should be individualized according to the clinical judgement arid serial observation. All patients with empyema do not need a chest CT scan but a CT scan can provide determination of loculation, guiding and assessing therapy which should decrease morbidity and hospital stay.

BACKGROUNDS: In the absence of distant metastasis, small cell lung cancer (SCLC) patients presenting with supraclavicular lymph node (SCLN) involvement and pleural effusion can benefit from thoracic radiotherapy. But there are some debate as to the prognostic significance of both SCLN involvement and pleural effusion. The purpose of this study was to determine the prognostic significance of SCLN involvement and pleural effusion in SCLC. METHODS: Two Hundred and fifteen patients with histologically confirmed small cell lung cancer, who were treated either at the Keimyung university Dongsan hospital and Kyungpook national university hospital from January 1994 to June 1998, were evaluated retrospectively. The patients were classified as having either limited or extensive stage using the Veterans Administration staging system. RESULTS: SCLN was presented in 10.5% of patients(n=21). The median survival was 247 days for patients with SCLN(n=21) and 264 days for patients without(n=194) (p=0.52). After treatment, the median survival was 298 days for patients with SCLN(n=13) and 348 days for patients without(n=115) (p=0.52). SCLN involvement was not correlated with the presence of distant metastases. Medican survival was 459 days for patients with a limited stage without SCLN(n=66), 650 days for those with a limited stage with SCLN (n=7) (p=0.96). Pleural effusion was presented in 24.7% of patients(n=52). The median survival was 198 days for patients with pleural effusion(n=52) and 275 days for patients without(n=163) (p<0.05). After treatment, the median survival was 294 days for patients with a pleural effusion(n=25) and 286 days for patients without(n=103) (p=0.39). The presence of pleural effusion was not correlated with that of distant metastases. The median survival was 395 days for patients with a limited stage without a pleural effusion(n=63), 451 days for those with a limited stage with pleural effusion(n=10) (p=0.92). CONCLUSIONS: In this study, SCLN involvement does not explain the poor survival rate and the relevance to extensive staged disease. Furthermore, the existence of a pleural effusion did not correlated with the presence of distant metastases. However, the presence of a pleural effusion appears to be a minor prognostic factor in our study. Therefore supraclavicular lymph node justify any amendment to the staging system currently used.

One of the moot important goals of modem gynexologic oncology is the adequate management of ocarian cancer. This includes early detection and differenciation of recurrence or residurd turnur. A promising method is availaible today with the use of mctabolic suubstrates used by tumor cells that are labeled with positron emittillg isotopes and a special instrument capable of detecting the radiations in vivo. Measuring tumor metabolic characteristics appear also to diffnencinte tumor recurrence or reeidual tumor from surgical or irradiation changes which is important since this wil1 not be defferentiaited by other modalities such ac CT or MRI. The goal of this study was to rletennine the potential utility uf whole-body PET using the giucose malogue 2-(18F)-fluoro-2-deoxy-D-glucoae(F-18-FDO for the detection of primey, metastatic, and recurrent ovarian cancer. Six patients had imaging studies prior to laparotomy for suspected ovarian cancer. PET(Positron Emission Tomogrnphy) scans were done with an ECAT 921(Emission Computed Axial Tomograpy 921, Sieinens/CTI. The result of this study show good correla- tion between PET nnd pathological findirs. The tumor detection rate of CT, MRI, CA-125, PET for ocarian cancer was 50%, 75%, 25%, 100% respectively. In summary, this work indicates that PET may be useful in the rnanagement of patients with ovwrian cancers by idengying occult foci of rnetabolically active tumor that do not appear on morphological studies.

The spontaneous regression (SR) of cancer is defined as the complete disappearance of a malignant disease without adequate treatment. SR is a very rare biological event, particularly in a pulmonary sarcoma. We report the first documented case of an endobronchial sarcoma that regressed spontaneously in Korea. We encountered a rare case of a 72-year-old woman with an undiagnosed intrapelvic cystic mass, who presented with a smooth surfaced endobronchial tumor obstructing the orifice of the right lower lobe bronchus on a bronchoscopic examination. She had a prior history cervical cancer and adenocarcinoma in the right middle lobe lateral segment of her lung for which she had undergone radiation therapy. The tumor was diagnosed as an endobronchial sarcoma by the histopathology findings and immunohistochemistry. It was unclear if the tumor was a primary sarcoma of the lung or a metastatic lesion of an intrapelvic cystic mass because she refused a diagnostic exploratory laparotomy. Two months later, obstructive pneumonia of the right lower lobe with parapneumonic effusion developed with fever above 38.5degrees C for 10 days. After recovering from pneumonia, she was followed up regularly in the outpatient clinic without any specific treatment. One year later after treating the obstructive pneumonia, the follow-up bronchoscopy revealed complete SR of endobronchial sarcoma. It is believed that the obstructive pneumonia accompanied by fever above 38.5degrees C for 10 days might have played a role in this SR.

PURPOSE: To investigate clinical characteristics of post-traumatic intraocular foreign body (IOFB), which occurred between 2006 and 2010, and prognostic factors associated with final visual outcome. METHODS: A retrospective chart review was performed of patients with IOFB who visited our clinic from January 1, 2006 to December 31, 2010, and who were followed up for more than 6 months. Cross tabulation and correlation analyses were conducted to evaluate the predictive factors related to final visual acuity. RESULTS: A total of 36 eyes (35 patients) were included in this study. The mean age was 44.2 years, and 33 patients (94.3%) were male. The most common cause of IOFB was lawnmower-related activity (12 patients; 33.3%) and hammering-related activity (11 patients; 30.1%). Among analyzed prognostic factors, only initial visual acuity was significantly correlated with visual outcomes (p < 0.001). CONCLUSIONS: Compared with previous studies, lawnmower and hammering-related activities were still the most common causes of IOFB, however, the incidence of occurrence in the 40's and 50's was relatively higher than in previous studies. Considering the poor visual outcome of IOFB even after proper surgical treatment, using proper eye protection should be emphasized in a dangerous work environment to prevent ocular trauma.

During the last decade, many clinical investigators at various cancer centers have reported the efficacy of various chemotherapeutic agents in the treatment of osteosarcoma. The regimens using high-dose methotrexate (HDMTX) with citrovorum factor rescue are now considered to be one of the most effective treatments of choice. From December 1989 to May 1991, sixteen patients with Enneking's stage (Enneking et al., 1980) IIB osteosarcoma of the extremities were treated with a high-dose methotrexate regimen. After two cycles of preoperative chemotherapy, an operation was performed; either limb salvage or amputation. The resected lesions were examined pathologically and classified according to Huvos' criteria. On pathological examination, 8 (50%) cases showed Grade IV; 1 (6.25%) Grade III; 4 (25%) Grade II; and 3 (18.75%) Grade I. The types of surgery performed were tumor prosthesis replacement (11); wide resection with or without reconstruction (2); resection and arthrodesis (1); and amputation (2).
