OBJECTIVE: To assess whether there is an association between improvement of computed tomography imaging results prior to interval debulking with survival in patients treated by neoadjuvant chemotherapy. METHODS: The clinical and outcome data of all advanced ovarian, primary peritoneal and tubal carcinoma patients who after diagnosis had neoadjuvant chemotherapy and underwent interval debulking during the period 2000-2010, were abstracted. Results of computed tomography imaging at diagnosis and prior to interval debulking were compared. Two parameters were assessed: the change of the size and number of abnormal findings and the change in the amount of ascites. CA-125 level response was also calculated. An assessment of progression free survival and of survival by the Kaplan-Meier method was made according to the change in computed tomography imaging results and according to response of CA-125 levels. RESULTS: The median progression free survival and the median survival of the 37 study group patients were 7.9 and 49.2 months respectively. No significant difference in progression free survival and survival was observed between patients with marked improvement in the computed tomography results and those with less desirable results (7.93 vs. 7.23 months respectively, p=0.89; 45.8% vs. 52.5% months respectively, p=0.95). There were also no statistically significant difference according to CA-125 level response. CONCLUSION: It seems that neither improvement in imaging results nor CA-125 level response can predict the survival of ovarian carcinoma patients prior to interval debulking after neoadjuvant chemotherapy.

PURPOSE: Hepatic resection and liver transplantation are considered a curative treatment for hepatocellular carcinoma (HCC) within the Milan criteria. In this study, we examine the outcome of hepatic resection for HCC within the Milan criteria, and determine the effectiveness of hepatic resection as the primary treatment for HCC within the Milan criteria in Child-Pugh class A. METHODS: 110 patients underwent curative surgical resection for HCC in Child-Pugh class A between August 1991 and June 2008. Fifty-six patients met Milan criteria (Group M) and the remaining 54 did not (Group N). RESULTS: Overall survival rates at 1, 3, and 5 years were 92.6%, 72.5% and 54.6% versus 70.4%, 43.1%, and 28.7% in Group M and Group N, respectively (P=0.0043). The corresponding disease-free survival rates were 81.5%, 69.7%, and 38.2% versus 46.0%, 32.9%, and 26.9% in Group M and Group N (P=0.0012). HCC recurred in 25 patients in Group M (44.6%) and 35 patients in Group N (64.8%)(P=0.034). Outcomes of hepatic resection in Group M were significantly better compared to Group N. CONCLUSION: Hepatic resection can achieve a comparable 5-year overall survival & disease-free survival to that reported for liver transplantation. Hepatic resection should be considered as the standard therapy for HCC within the Milan criteria in Child-Pugh class A patients.

Authors analyzed the results of treatment in 49 cases of medulloblastoma who had been operated upon at the Seoul National University Hospital from January 1972 to June 1987. There were 2 cases(4%) of postoperative mortality(death within postoperative one month) and 13 cases of late moratlity. The 3-year overall survival rate was 49.3% and 3-year disease-free survival rate was 48.5%. The risk period of recurrence was about 2 years after surgery. The 3-year survival rate was significantly better in "grow total resection" group, "radiation dose more than 50 Gy" group, and group II(23 cases operated after July 1982) (p<0.05). The rate of posterior fossa recurrence was lower in "gross total resection" group for the patients who received posterior fossa irradiation of more than 50 Gy.

PURPOSE: We analyzed the clinical outcome of osteosarcoma developed in distal radius and the effect of delayed treatment on prognosis. MATERIALS AND METHODS: Twelve patients with distal radius osteosarcoma were analysed. We categorized patients into two groups of standard treatment or non-standard treatment. The patients of standard treatment group are all stage IIB and non-standard treatment group includes five stage IIB and one stage III. RESULTS: Five-year overall survival and disease-free survival rates of standard treatment group were 100% and 83%. Five-year overall survival rate of non-standard treatment group was 44%. Between two group, there are differences in age, tumor size, surgery type, symptom duration. CONCLUSION: Distal radius osteosarcoma have good prognosis than other extremity osteosarcoma. Survival rate of non-standard treatment group were lower than standard treatment group. Although the prognosis of non standard treatment group is poorer, the duration till death was longer than that of other sites with similar condition. Further multi-institutional study should be needed.

5.Event Free Survival after Acute Myocardial Infarction.
Korean Circulation Journal 1987;17(4):735-742
Survival after acute myocardial infarction (AMI) is related to the number of diseased vessel, ejection fraction, extent of residual ischemic tissue, presence of ventricular arrhythmia. Because a variety of revascularization modalities are tried in recent years, the natural course after AMI seems to become difficult ot assess. From the experience of 129 cases of coronary angiography in AMI from Jan 1984 to Apr 1987, the factors related to invasive modality were analysed to evaluate the effect on the survival after AMI. The following results are obtained. 1) Single vessel disease and insignificant lesion were present in 60%, and multivessel disease comprised 40% in all group. 2) Patients were followed for a mean of 16.3 months and 2 cases(1.6%) expired suddenly and reinfarction developed in 6 cases(4.7%). 3) After exclusion of 4 cases taken CABG operation, the event free survival of all patients was 0.98, 0.90, 0.78, 0.78, 0.78 in double vessel disease, 0.94, 0.87, 0.87, 0.77, 0.51 in triple vessel disease. The survival was better in single vessel disease compared to multivessel disease (p<0.05), but no difference was present between double and triple vessel disease. 5) Event free survival in group with left ventricular end diastolic pressure(LVEDP) >16mm Hg was better than that of a group with LVEDP <16mm Hg. But no difference was present between group with ejection fraction <40% and group with ejection fraction >40%. From the above results, it can be concluded that the event free survival after mainly uncomplicated AMI in Koreans depends on the number of diseased vessel and LVEDP.

BACKGROUND: Parafibromin is a recently defined tumor suppressor gene. The aim of our study was to determine the relationships of parafibromin expression in urothelial carcinomas (UCs) with prognostic parameters and to evaluate the use of parafibromin as a potential marker of UC. METHODS: Parafibromin expression was assessed in 49 UC specimens using immunohistochemistry. The correlations between parafibromin expression and clinical and pathologic parameters were investigated. RESULTS: Of the patients, 42 (85.7%) were male, and the mean age was 69.6 +/- 8.2 years (range, 54 to 88 years). Morphologically, the UCs were divided into two groups: papillary (n = 27) and non-papillary (n = 22). There were seven low-grade (14.3%) and 42 high-grade (85.7%) tumors. Parafibromin was negative in 13 tumors (26.5%), partially positive in 19 tumors (38.8%), and positive in 17 tumors (34.7%). Parafibromin expression was more negative in UCs from upper urinary locations (n=17) and with muscularis propria invasion (n=28), which was statistically significant (p = .009 and p = .007, respectively). There was no statistically significant relationship between parafibromin expression and gender, age, tumor grade, survival, or disease-free survival. CONCLUSIONS: We found that UC cases with parafibromin positivity had less of a tendency to show muscularis propria invasion and were more commonly located in the lower urinary system. These results need to be confirmed with studies based on larger case series.

BACKGROUND: Transcatheter hepatic arterial chemoembolization (TACE) is used for curative or palliative treatment of hepatocellular carcinoma (HCC). However, it is neither well known how much TACE induces tumor necrosis histologically, nor whether preoperative TACE has benefit for resectable HCC. The purpose of this study is to measure the degree of tumor necrosis induced by one session of TACE and to evaluate the effect of preoperative TACE for resectable HCC. METHODS: Between January 1999 and January 2004, 20 HCC patients with one session of preoperative TACE (TACE group) and 36 HCC patients with only preoperative hepatic angiography, without TACE (angiography group) were enrolled. RESULTS: In TACE group, 12 patients had tumor necrosis of 100%, 5 patients having between 80% and 99%, and 3 patients less than 50%. The mean tumor necrosis rate of HCC less than 5 cm in diameter were 84.7%, while 90.5% in larger size (>5 cm in diameter) of HCC (p>0.05). The mean tumor necrosis rate of the recurred patients in TACE group and in angiography group was 98.75 and 17.5% (p=0.02), respectively. Disease free survival time of the recurred patients in TACE and in angiography group was 16.75 and 20.25 months, respectively (p=0.77). CONCLUSIONS: The tumor size was not related with the degree of tumor necrosis and no relevant factors could be found. Although the mean tumor necrosis was greater in TACE group than in angiography group, the disease free survival time was not different between the two groups.

BACKGROUND: Chromophobe renal cell carcinoma is a category of renal cell carcinoma composed of histologically characteristic tumor cells. E-cadherin is an intercellular adhesion protein that has been correlated with tumor aggressiveness in many carcinomas, including clear cell renal cell carcinoma. However, the significance of an E-cadherin expression in chromophobe renal cell carcinoma is not known. METHODS: We evaluated the E-cadherin expression status of 65 chromophobe renal cell carcinomas by performing immunohistochemical staining with the tissue microarray method. The percentage of positively stained tumor cells was evaluated and this was then classified into two categories: a low expression where 0 to 25% of the cells are positive, and a high expression where more than 25% of the cells are positive. RESULTS: Among 65 cases, 11 cases (17%) showed a low expression, and 54 cases (83.0%) showed a high expression. The tumors with low expression were more likely to have a higher stage but this was not significant (p=0.056). On the survival analysis, a low E-cadherin expression was significantly associated with poor cancer-specific survival (p=0.005) and progression-free survival (p=0.003). CONCLUSIONS: The E-cadherin expression is a good prognostic marker for survival in patients with chromophobe renal cell carcinoma.

BACKGROUND/AIMS: The Follicular Lymphoma International Prognostic Index (FLIPI) and FLIPI2 are well-known prognostic models for patients with follicular lymphoma (FL). However, their prognostic relevance has not been examined before in Korean patients with FL. METHODS: We reviewed clinical and laboratory information from our database of patients between 1995 and 2012. In total, 125 patients were stratified in three categories according to FLIPI or FLIPI2 scores: low-, intermediate-, and high-risk groups. We compared FLIPI and FLIPI2 in terms of progression-free survival (PFS) and overall survival (OS). RESULTS: Among the 125 patients, the prognostic value of FLIPI and FLIPI2 was evaluated in 73 patients who fulfilled the criteria of both prognostic models. Risk stratification by FLIPI and FLIPI2 showed significant differences in unfavorable parameters among each risk group, particularly between low- and intermediate-risk groups. The high-risk group b was significantly associated with poor PFS on both FLIPI and FLIPI2 (p < 0.05). However, the OS was significantly different only in the risk groups determined by FLIPI2 (p = 0.042). In a subgroup analysis of patients who received rituximab-containing chemotherapy, the risk stratification of both prognostic models showed a significant impact on PFS, especially in the low-risk group. CONCLUSIONS: FLIPI and FLIPI2 are appropriate prognostic models in Korean FL patients, especially for discriminating low-risk patients from intermediate- and high-risk groups.

PURPOSE: We sought to determine if organ preservation (OP) with neoadjuvant chemoradiation (CRT) was feasible in patients with sinonasal cancer determined to require exenteration. MATERIALS AND METHODS: Twenty patients were determined to require exenteration for definitive treatment from 2005 to 2014. Fourteen patients underwent OP and 6 patients received exenteration with adjuvant CRT. Exenteration free survival (EFS), locoregional control (LRC), progression-free survival (PFS), and overall survival (OS) were estimated. RESULTS: Five patients (36%) receiving OP had complete disease response at time of surgery. With a median follow-up of 18.8 months, EFS was 62% at 2 years for patients undergoing OP. At 2 years, there were no significant differences in LRC, PFS or OS (all all p > 0.050) between the groups. Less grade 3 or greater toxicity was seen in patients undergoing OP (p = 0.003). Visual function was preserved in all patients undergoing OP. CONCLUSION: For patients with sinonasal cancer, OP may avoid exenteration, offering similar disease control and improved toxicity.
