Prior to 1988, endometrial cancer was clinically staged but there was the considerable discrepancy between clinical and aetual stage. FIGO surgical staging classification of endometrial cancer(I988) provides the advanatage of recognizing the true disease distribution and extension, and more rational treatraent can be accomplished. This retrospective study was based on a clinical review of 73 patients with endometrial carcinoma from l982 through 1991 who underwent primary surgical evaluation. A11 cases were restaged ueing the newly adopted FIGO surgical staging. The distribution of FIGO clinical staging was as follows:85 patients(89.1%) were with stage I, 5(6.9%) with stage II, 2(2.7%) with stage III and 1(l.3%) with stage IV. Surgical restaging according new FlG0 classification reveald 56(76.7%) patients with stage I, 1(1.4%) with stage II, 14(19.2%) with stage III and 2(2.7%) with stage IV. Surgery upstaged 12.3% of clinical stage I patients, In clinical stage II patients, 80.0% was doenstaged. There wes no stage changing in cliaical stage III and IV patients. The acturial survival rates for surgical stages I a, I b, I c, and III were 80.0%, 77.2%, 68.4A%, and 35.0% respectively. By using FIGO surgical staging, the initial extent of endometrial cancer can be more accurately evaluated and we may predict prognosis and survival relatively well.

Streptococcus anginosus is a member of Streptococcus milleri group, and is found in the oral mucosa, respiratory tract, and gastrointestinal tract as normal flora. It can develop into a disease in patients with deteriorating clinical condition or with clinical risk factors. A previously healthy 15-year-old boy was admitted due to fever, abdominal discomfort and vomiting which lasted for 7 days. He had a history of dental procedure 1 day before the development of fever. He was diagnosed with acute acalculous cholecystitis based on the clinical, laboratory, and imaging finding, and S. anginosus was isolated from the blood culture. The patient was successfully treated with antibiotic therapy.

The back pain is increasingly becoming a major problem in the elderly people. The cause of back pain in the elderly patient is quite different from in the young subject. And relationship of the occurrence of osteoporosis with the incidence of fractures in general is currently regarded as a major factor. The authors performed clinical observation on 194 elderly patients who were treated for back pain during 5 years period from April, 1983 to April, 1988 at the Department of Orthopaedic Surgery, Severance Hospital and relationship between osteoporosis and compression fracture of spine was reviewed. The results were as follows : l. Among the 194 cases of back pain(28.3% of total admission cases), whose age were over 50: 142 cases were female and 52 cases were male, being more common in female. 2. Most common cause of back pain was the compression fracture of spine : 86 cases(44.3 %). Osteoporosis was associated with 66 cases(76.7%) out of 86 cases. 3. The number of compression fracture in same patient was more frequent in osteoporotic patient and thoracolumber junction (T12, Ll) was the major site of fracture (45.6%). Compression fracture of spine caused by osteoporosis occured at multiple level in 60.6%. 4. Twenty three cases(34.8%) of compression fracture of spine with osteoporosis were found to have previous history of fractures of spine and/or extremities by radiological examination. Regarding this results, compression fractures of spine was not infrequent cause of back pain in the elderly. It was thought that re-fracture of spine should be prevented by vigorous approach against osteoporosis along with the treatment of presenting fracture in these patients.

Since 1952, Ilizarov external fixator has been developed and used for more than 30 years in Russia and world-wide interest on it has been prevalent during last 2-3 years. The fixation of the tension applied thin wires to the metal frame resist flexional and translational deformity just like other extenal fixators. But, it allows cyclic axial micro-motion at the fracture site without loss of reduction so that it can provide good environment for the fracture healing biologically and biomechanically. Another advantage of Ilizarov external fixator is that it permits mobilization of the adjacent joints and weight bearing of the fractured limb during the application of it and shortens the duration of administration. Since 1988, We applied the Ilizarov external fixator for the treatment of diffcult tibial fractures (open comminuted, segmented and comminuted fractures, nonunion, maunion) and obtained good results in 7 cases. So we report our results even if we had limited cases and experiences.

Lipoma arborescens is a rare intra-articular lesion consisting of a villous lipomatous proliferation of the synovial lining. We experienced one case of lipoma arborescens of knee which was associated with avascular necrosis of femoral head. This case report draws the attention to history, physical findings, MR images, pathologic findings and arthroscopic appearance of this rare lesion. Arthro;copically, the lesion appears as a synovial lesion with numerous fatty-appearing globules and villous projections. Although the etiology is unknown, lipoma arborescens has been described in association with osteoarthritis, rheumatoid arthritis and diabetes mellitus. MR imaging is diagnostic choice to differentiate the lesion from rheumatoid arthritis, pigmented villonodular synovitis and synovial chondromatosis in those patients who present with chronic, swollen and painfui joint. Arthroscopic removal was effective in this case and we think that treatment choice of this lesion is arthroscopic removal.

OBJECTIVE: This study was performed to identify the prognostic factor for survival of patients with recurrent cervical cancer. METHODS: Sixty-eight patients were diagnosed as recurrent cervical cancer at the Seoul National University Hospital from January, 1988 to December, 1998. Recurrence was defined as new evidence of tumor after 6 months of disease free survival. Retrospective analysis was done in terms of clinical features and the Cox proportional hazard model was used to identify independent variables associated with an improved survival rate. Histopathologic types were distributed as follows; squamous cell carcinoma in 70.6%, adenocarcinoma in 11.8%, adenosquamous cell carcinoma in 11.8%, and small cell carcinoma in 1.5%. Distribution of FIGO stage was as follows; stage I in 25.0%, stage II in 66.2%, and stage III in 4.4%. Sites of recurrence were as follows; central pelvic recurrence in 44.1%, pelvic side wall recurrence in 11.8%, and distant metastasis in 44.1% and the most common site of distant recurrence was extrapelvic lymph nodes (29.4%). 29.4% of recurrences were observed within the first 12 months after initial therapy, 50.0% within 2 years and 64.7% within 3 years. RESULTS: Positive rate of SCC-Ag at initial diagnosis was 45.2% with cutoff value of 2.0 ng/ml. Positive rate of SCC-Ag at the diagnosis of recurrence was 60.0%. Overall response rate to the treatment was 29.1%. Complete response rate was higher in central pelvic recurrrence than pelvic side wall recurrence and distant metastasis (P = 0.002) and also higher in normal SCC-Ag level (< or = 2.0 ng/ml) at the diagnosis of recurrence than elevated level (P = 0.032). Cumulative survival rates of 1 year after recurrence was 66.8%, 2 year 36.7%, and 5 year 18.7%. Central recurrence showed higher cumulative survival rate than pelvic side wall or distant recurrence (P = 0.029). The patients with elevated SCC-Ag level at the time of diagnosis of recurrence showed lower cumulative survival rate than those with normal SCC-Ag level (P < 0.001). Cox proportional hazard model showed that SCC-Ag elevation at the time of diagnosis of recurrence retained significant values in predicting survival(OR = 2.56; 95% CI = [1.22-5.39]; P = 0.01). CONCLUSION: SCC-Ag elevation at the diagnosis of the recurrence is a strong independent prognostic indicator for survival of patients with recurrent cervical cancer.

Interferon(IFN) has been noted to augment the cytotoxicity of cisplatin analogues and S-FU, and varying degrees of success were reported when combined with chemotherapy in a number of squamous cell carcinomas. The aims of this study were to assess its therapeutic efficacy and to establish the feasibility and toxicity of biochemical modulation of the interferon-a-2a when combined with 5-FU and carboplatin(CBDCA) in locally advanced(> or =FIGO clinical stage IJb) and/or bulky(largest diameter > or = 3cm) cervical cancer. From January 1995 to December 1996, 20 patients with bulky and/or locally advanced cervical cancer were enrolled in this study and received FAC(5-FU/Interferon-a/CBDCA) combination chemotherapy as a neoadjuvant setting. The FAC regimen was composed of IFN- a -2a 3x10(6) IU/day from day l to day 6, 5-FU 750mg/m2/day from day 2 to day 6, and carboplatin at a dose calculated by Calvert formula with AUC(area under the curve) 6.0 on day 2. Three cycles of neoadjuvant chemotherapy was performed with 3 weeks interval if toxicity permitted it. Patients were examined after every treatment cycle and evaluated for toxicities and responses using standard GOG criteria. Two patients(10.0%) showed complete clinical response and 15 patients(75,0%) had partial response. The other patients had stable(10.0%) or progressive disease(5.0%). Among fifteen patients who have undergone radical hysterectomy, pathological complete response was not noted. Surgery was possible in 15 patients(75.0%) and 10 patients received adjuvant radiotherapy. Lymph node metastases were found in 5 patients(33.3%) and the number of positive nodes was ranged from 1 to 5. The most frequent grade 3 or 4 toxicity was neutropenia(60.0%) followed by alopecia(40.0%), nausea/vomiting(35.0%), thrombocytopenia(15.0%), diarrhea(5.0%), and anemia(5.0%). (continue)

OBJECTIVE: Large loop excision of transformation zone(LLETZ) is gaining popularity as an alternative to other ablative or cone methods for the treatment of cervical intraepithelial neoplasia(CIN). The optimal management of CIN after LLETZ, however, remains controversial and the reliable predictors of residual disease after LLETZ have not been consistently identified. This study was performed to identify factors to predict residual disease after LLETZ. METHODS: From August 1993 to July 1995, 133 patients who received subsequent hysterectomy after LLETZ in Department of Obstetrics and Gynecology at Seoul National University Hospital were retrospectively reviewed. Residual disease was defined as positive findings of CIN or further advanced findings in hysterectomy specimen. The age of patients, the severity of disease and the status of resection margin(RM) were analyzed for predictive values of residual disease. The Chi-square test, Fisher's exact test and Student t-test were used for statistical analysis. RESULTS: The residual disease after hysterectomy was negative in 85.7%(114/133) and positive in 14.3%(19/133). Among 19 cases with positive residual disease, 3 cases were revealed to be microinvasive cervical cancer. The mean age of patients with no residual disease was 42.5 years(range; 27-71) and that of patients with residual disease was 49.1 years(range; 33-72). Nine out of 94 cases(9.6%) with negative RM and 10 out of 39 cases(25.6%) with positive RM in LLETZ had residual disease. Two out of 14 cases(14.3%) with CIN II and 17 out of 119 cases(14.3%) with CIN III in LLETZ had residual disease. The success of LLETZ which means no residual disease was influenced by the age of patients(p=0.005) and the status of resection margin of LLETZ(p=0.032). CONCLUSION: The negative resection margin in LLETZ does not always guarantee that there is no residual disease. Close preoperative workup and more aggressive treatment plan(wide conization or hysterectomy) should be considered in patients who has higher possibility of positive residual disease such as old age and positive resection margin in LLETZ.
