BACKGROUND: Surgical resection remains the mainstay of treatment for esophageal cancer. Despite recent advances in surgical therapy, i.e. en bloc resection and extended lymphadenectomy, the overall long-term prognosis of patients with esophageal carcinoma has not, however, improved during the last decades. One of the major reasons in its relatively high recurrence rate. MATERIAL AND METHOD: A retrospective review of recurrent patterns of cancer in 42 patients who underwent curative surgery for primary esophageal cancer was performed clinically and histo-phthologically. RESULT: Nineteen patients had developed recurrece during the 18 to 52 months(mean 34.2 nonths), 8 had local recurrences, 1 had both, and 11 had systemic recurrences. Twelve patients(63%) had developed recurrence within 1 year, 5 patients(26%) between 1 year to 2 patients(11%) after 2 years. The recurrence rate according to growth pattern of tumor or presence of microinvasive findings was not statistically significant, but it increased significantly in clinical tumor stage III than stage IIA, B and in patients with the number of metastatic lymph node over ten. CONCLUSION: Post-operative recurrences of esophageal cancer appear as a high rate even though curative wide resection was done. Several clinical and histo-pathological factors correlate with the recurrence.

PURPOSE: Prostatic tumor induced gene-1 (PTI-1) is a mutated human EF-la and putative prostatic carcinoma tumor-inducing oncogene, that is differently expressed in prostatic cancer and benign prostatic hyperplasia. And, it is more sensitive marker than prostate- specific antigen (PSA) for detecting human prostate cancer in the bloodstream. This study invastigated the expression of PTI-1 in paraffin embedded tissue of prostatic carcinoma, prostatic intraepithelial neoplasia, and benign prostatic hyperplasia using in situ PCR. MATERIALS AND METHODS: we evaluated expression of PTI-1 in prostatic carcinoma with prostatic intraepithelial neoplasia (PIN) of 32 cases, benign hyperplasia of 20 cases, high grade transitional cell carcinoma of 10 cases and colon cancer of 10 cases for control group. Also, the immunohistochemical staining for PSA was performed to comparison with clinical value of PSA. RESULTS: The serum level of PSA was closely related to stage and Gleason score (p < 0.05). However, the results of immunohistochemical stains were variable to stage and Gleason score. PTI-1 using in situ PCR expressed in 50% of prostatic carcinoma, 41% of prostatic intraepithelial neoplasia, 10% of benign hyperplasia and colon cancer (p < 0.05). No expression is observed in transitional cell carcinoma. In prostatic carcinoma, PTI-1 expressed in 43.8% (7/16) of stage II, 50.0% (5/10) of stage III, and 66.7% (4/6) of stage IV (p<0.05). In PIN, expression of PTI-1 was similar to prostatic carcinoma (p<0.05). CONCLUSION: PTI-1 represented a relatively sensitive marker for prostatic carcinoma and PIN, indicator of prostatic carcinoma progression.

Emphysematous cystitis is a rare condition characterized by gas collection in the wall and lumen of the bladder. We experienced three cases of emphysematous cystiris. All patients were female; one was associated with a long term history of diabetes mellitus and another with urinary indwelling catheter. All of the cases were easily diagnosed on plain radiograph and CT scan, and were successfully treated with antibiotic therapy. In one of the cases, however, associated abscess due to perivesical extension of inflammation was treated by combined external drainage.

BACKGROUND: DNA topoisomerase II-alpha is linked with active cell proliferation in mammalian cells. The aim of this study was to examine the relationship between the expression of DNA topoisomerase II-alpha as a proliferating marker, and the expression of Ki-67 and apoptosis in urothelial carcinoma of urinary bladder based on World Health Organization/International Society of Urological Pathology (WHO/ISUP) consensus classification. METHODS: 73 urothelial carcinomas of the urinary bladder after transurethral resection and 25 carcinomas after radical cystectomy were investigated for histologic grading based on WHO and WHO/ISUP consensus classification. Formalin fixed, paraffin embedded tissue of 98 specimens from 73 patients were immunohistochemically stained for DNA topoisomerase II-alpha and Ki-67, and in situ TdT-mediated dUTP-biotin nick end labeling method for evaluation of apoptotic cells was performed. For each case, a DNA topoisomerase II-alpha, Ki-67, and apoptotic indices were determined. RESULTS: The histologic grades of 73 cases based on the WHO grading system were 21.9% (16 cases) in grade 1, 65.8% (48 cases) in grade 2, and 12.3% (9 cases). 5.5% (4 cases) of papillary neoplasm of low malignant potential, 47.9% (35 cases) of urothelial carcinoma of low grade, and 46.6% (34 cases) in urothelial carcinoma of high grade were reclassified using the WHO/ISUP consensus classification. Histologic grades based on two grading systems were correlated to invasion and stage (p<0.05). DNA topoisomerase II-alpha, Ki-67, and apoptotic indices were correlated to histologic grades based on two grading system and invasion. Also, the correlation of DNA topoisomerase II-alpha and Ki-67 indices, and DNA topoisomerase II-alpha and apoptotic indices were significant, respectively. CONCLUSIONS: DNA topoisomerase II-alpha appears to be an useful marker for assessing the proliferation potential of urothelial carcinoma of in the urinary bladder.

BACKGROUND/AIMS: The role of dietary factors in the pathogenesis of irritable bowel syndrome (IBS) is still unclear. The aim of this study was to compare IgG4 levels to common food antigens between patients with IBS and healthy controls. METHODS: Thirty-two patients diagnosed as IBS according to the Rome III criteria (12 diarrhea subgroup; 20 non-diarrhea subgroup) and 32 sex and age-matched healthy controls participated in the study. Serum IgG4 titers to 90 common foods were measured in each subject. The number of subjects with positivity defined as the cut-off value ≥ 0.7 U/mL was compared. RESULTS: Patients with IBS had significantly higher IgG4 titers to wheat, leek and taro compared to those of controls. Serum IgG4 titers to ginger, cocoa, walnut, white radish, onion, and lettuce in IBS patients tended to be higher than controls. IgG4 titers to wheat, gluten and gliadin in the diarrhea subgroup, and lettuce, leek and taro in the non-diarrhea subgroup tended to be higher compared with controls. The number of subjects with positivity to apple, orange, lettuce, and leek was significantly higher in IBS patients than controls. The number of subjects with positivity to apple, orange, gluten, and gliadin in the diarrhea subgroup, and egg white, pineapple, soybean, lettuce, and leek in the non-diarrhea subgroup was significantly higher compared with controls. CONCLUSIONS: Serum IgG4 antibody levels to some common foods are abnormally elevated in IBS patients. The type of foods with abnormally elevated serum IgG4 titers in the diarrhea subgroup may be different from that in the non-diarrhea subgroup.

PURPOSE: Three-dimensional(3D) magnetic resonance(MR) projection imaging was evaluated as a noninvasive alternative to direct cholangiography for the assessment of its reliability in patients with obsructive jaundice. METHODS AND MATERIALS: A heavily T2-weighted gradient-echo sequence(PSIF) was used for 3D MR projecion imaging of the biliary system in five healthy volunteers and 25 patients with obstructive jaundice. The 3D images of the bile ducts were formed by stacking consecutive coronal MR images obtained with a fast imaging method to a maximum-intensity projection algorithm. RESULTS: In the volunteers, MR cholangiography could demonstrate the anatomy of the biliary tract in only two subjects. The extrahepatic and intraheparic bile ducts were well visualized in 23 patients with obstructive jaundice. The leve of obstruction and the grade of dilatation were dipicted with MR cholangiography in all cases. And the cause of obstruction could be determined with MR cholangiography in 18 cases, MR cholangiography was successful in two patients in whom ERCP failed. The gallbladder or dilated pancreatic duct not demonstrated by means of direct cholangiography was demonstrated with MR cholangiography in six cases.

The purpose of this study was to investigate whether the Bone Mineral Density (BMD) in a postmenopausal women has affected by a long-term swimming exercise. Swimming exercised 9 female and non-exercised 13 female were involved in this study. All of them were accepted by selection criteria through a questionnaire and personal interviews. Experimental group performed regularly swimming exercise while over a 8 year, but control group never taken part in any activities periodically. Bone densities were measured at Lumbar 2-4 and Femur's 3 sites (neck, ward's triangle, and trochanter) with DEXA method (Lunar DPX). There are no significant differences between two groups on the ages, body weights, heights, % fats, and menopausal durations. Bone densities on the neck and ward's triangle of Femur were 1.7% and 2.7% higher in the control group than in the swimming group, not significant between two groups. In the case of Femur trochanter and Lumbar 2-4 sites, swimming group however were nonsignificantly higher 2% and 5.3% than control group, respectively. In conclusion, it was recognized that a long-term swimming exercise may be ineffective to intensify local density, stiffly lowering in a postmenopausal women.

The authors analysed the CT findings in 75 cases diagnosed as gastric carcinoma by U.G. I.S. or endoscopy in a 3)1, year period. The comparative analysis betw~en CT findings and surgical pathologic findings was done in 55 cases who underwent surgery. 20 cases could not be operated upon because of distant metastasis. The gastric carcinoma was devided into 4′ stages according to the staging system of the American joint Committee on Cancer. The CT findings were then compared and the following results noted : 1. The relationship with gastric wall thickening and penetratioil degree of tumori no thickening (Iesser than 1.0 cm) of 3 cases showed all of T1, 11 of localized thickening (1. 0.1 .5cm) showed 7 of T2, 38 of localized thickening (more than 1.5 cm) showed 37 of T3 and 3 of diffuse thickening showed all of T4a. 2. The accuracy of Iymph node detection by CT scan, 1) Regionaf tymph node showed 86% in operative f in ding and 73% in pathologic. 2) Extragastric Iymph node showed 87% in operative finding and 89% in pathologic. 3) Retro-peritoneallymph node showed 96% in operative finding and 95% in pathologic. ic. 3. In operated cases, there was one case of false positive distant metastasis and three false negative cases. 20 cases of non-operated cases showed distant metastasis such as liver, lung or kidney. 4. 55 cases were classified as stage 1 in 4 cases, 11 in 18, 111 in 23 and IV in 10 by pathologic findings, and 1 in 3, 11 in 24, 111 in 19 and IV in 9 by CT. The overall accuracy by CT stagi ng is 75%. 5. Among a total of 75 cases, there were 46 operable cases by CT finding an d 43 operabl e cases by pathologic staging. There we re 29 inoperable cases by CT finding and 27 cases by pathologic staging. Therefore, there was a 93% overall accuracy by CT stagi ng in terms of determination of operability. 6. The accuracy of adhesion into adjacent structure by CT finding was 69%. compared with operable finding.
