PURPOSE: The prognosis of non-Hodgkins lymphoma (NHL) in elderly patients seems to be poorer than that in patients aged less than 60 years. This may be due to the lower tolerance for combination chemotherapy in the elderly. Aggressive combination chemo-therapy, which is the treatment of choice in intermediate and high grade NHL of adulthood, may be associated with unpredictab1y severe and lethal toxicity and worsened quality of life in the elderly. We investigated the treatment responses, toxicities and prognostic factors of NHL in elderly patients treated with combination chemotherapy. MATERIALS AND METHODS: We treated 116 elderly (>60 yrs) patients with NHL between January 1986 and June 1996 with adriamycin-containing regimens, such as CHOP (cyclo- phosphamide, adriamycin, vincristine, prednisolone), BACOP (bleomycin, adriamycin, cyclophosphamide, vincristine, prednisolone), and mBACOP (methotrexate, bleomycin, adriamycin, cyclophosphamide, vincristine, prednisolone). Patients in this study ranged from 60 to 81 (median 67) years of age. Fifty-five percent of patients were in stage I or II and the rest (45%) were in stage III or IV. The histologic grade was predominantly (91%) of intermediate and high grade type. RESULTS: The treatment responses were complete (CR) in 55% and partial (PR) in 25%. The median durstion of CR was 32 (3-132) months. The CR rate was significantly higher in patients treated with RDI (relative dose intensity) > 75% than that in the patients treated with RDI < 75% (p 0.003), but there was no significant difference in CR rate between treatment regimens (p-0.38). At a median follow up of 48-months (range, 12 to 132 months), the estimated 5-year ovetall survival was 46%. Ann Arbor Stage (I, II vs III, IV), ECOG performance (0-1 vs 2-3), RDI (>75% vs <75%) and the treatment response were important prognostic factors in the univariate analysis, and the treament response (CR vs non-CR) was the only independent prognostic parameter in the multivariate analysis. The most frequent and severe toxicity associated with chemotherapy was infection with or without neutropenia. The rate of severe infection was significantly decreased in the patients supported with G/GM-CSF but not in the dose-reduction group (RDI<75% vs >75%). CONCLUSION: Our data suggests that achievement of the CR after combination chemotherpy is the most important prognostic factor in the elderly patients with NHL. Suboptimal chemotherapy (RDI<75%) reduced the complete remission rate without reducing the likelihood of developing severe toxicities. Optimal chemotherapy with supportive cares involving the use of hematopoietic growth factors may be needed to improve the treatment response and the survival in the elderly patients with aggressive NHL.

Dermoid cysts are rare congenital tumors that occur primarily at the midline at a characteristic intradural location. However, dermoid cysts located at extradural and lateral regions have been rarely reported until now. In the present study, the authors demonstrate the unusual instance of an intracranial extradural dermoid cyst at the lateral sphenoid ridge. A 53-year-old woman admitted because of progressive headache and dizziness. The patient had no neurologic deficits, and magnetic resonance imaging with no contrast enhancement revealed a mass at the right sphenoid ridge. The mass was accompanied with sphenoid bone erosion visible on computed tomography. The patient underwent right pterional craniotomy, and the tumor including the capsule was totally resected. Presence of a dermoid cyst was confirmed with histopathological examination. The patient had no complications during the postoperative period. This study suggests that dermoid cyst should be considered for differential diagnosis of extradural and lateral intracranial masses.

Angiofibromas originate predominantly from the posterolateral wall of the nasopharynx and are typically seen in adolescent males, but they may also exist outside of the nasopharynx. Nine patients with extranasopharyngeal angiofibromas have been reported in Korea. The inferior turbinate was the most commonly affected site, and patients reported experiencing various nasal symptoms, such as epistaxis and nasal obstruction. Extranasopharyngeal angiofibroma arising from the superior turbinate is extremely rare and has not been reported to date. Recently we experienced a case of angiofibroma of the left superior turbinate in a 68-year-old male that was successfully treated with endoscopic surgery.

PURPOSE: The purpose of this study was to evaluate the clinical effectiveness of and patient's satisfaction with treatment of gingival melanin hyperpigmentation with a Nd:YAG laser and a high speed rotary instrument. METHODS: Three patients with melanin hyperpigmentation in the anterior parts of the gingiva were chosen for this case study. Clinical photographs were taken at the preoperative state and three patients were treated under local anesthesia. In the maxilla, the gingival deepithelization was conducted with a high speed diamond bur, whereas, in the mandible with a Nd:YAG laser. Clinical photographs were taken immediately after the procedures and at the 1st, 2nd, and 4th week to evaluate clinical color changes. A week after the procedure, the patients filled out a questionnaire about any pain or discomfort. At the 4th week after the procedure, the patients filled out questionnaires about esthetic aspects of the results of treatment. RESULTS: In all cases, both anterior gingival areas were depigmented with satisfaction and the patients did not complain of severe pain or discomfort. At the 1st week of healing, the gingiva showed moderate to fast epithelization. Two weeks after the procedure, clinically, the gingiva showed almost complete healing. Four weeks after the procedure, there was significant improvement in gingival melanin hyperpigmentation. CONCLUSIONS: The Nd:YAG laser and the high speed rotary instruments seem to be effective for the esthetic treatment of gingival melanin hyperpigmentation.

PURPOSE: Revascularization is a useful method for treating Kienbock's disease. The aim of this study was to evaluate the use of the second dorsal metacarpal vascular pedicle to treat Kienbock's disease. MATERIALS AND METHODS: A retrospective study was carried out on 9 patients who had undergone vascular pedicle graft for Kienbock's disease between 1999 and 2003. The mean follow up period was 35 months. At the time of surgery, 2 patients were graded as stage II, 6 as IIIa and 1 as IIIb. The ulnar variance was neutral in all cases. A vascular pedicle graft using second dorsal metacarpal vessel were performed and temporary scaphotrapeziotrapezoid (STT) fixation were applied for 6 months. RESULTS: Wrist motion except for the radial deviation and grip strength had improved significantly. The patients returned to work after an average of 22 weeks. Resorption of the sclerosis was observed in 7 cases, but lunate collapse was observed in the simple radiograph in 6 cases. According to Lichtman's criteria, 7 cases were satisfactory but 2 cases with a relative old age were unsatisfactory. According to Nakamura's classification, 5 cases were good, 3 cases were fair and 1 case was poor. CONCLUSION: In Kienbock's disease with neutral ulnar variance, a revascularization procedure of vascular pedicle graft with temporary STT fixation is a good treatment method but the patient's age should be considered when determining the revascularization procedure. A prospective study will be needed to determine the optimal duration of temporary STT fixation.

PURPOSE: Metabolic syndrome (MS) is a clinical condition that shares many common characteristics with diabetes. However, unlike diabetes, the usefulness of MS as a prognostic entity in peripheral arterial disease is uncertain. This study evaluated the prognostic usefulness of MS in critical lower limb ischemia (CLI) patients. MATERIALS AND METHODS: We compared the 2-year clinical outcomes in 101 consecutive CLI patients (66+/-14 years; 78% men) with 118 affected limbs treated with percutaneous transluminal angioplasty (PTA) according to the presence of MS and diabetes. RESULTS: The number of MS patients was 53 (52%), of which 45 (85%) had diabetes. During a 2-year follow-up, the incidence of clinical outcomes, including reintervention, major amputation, minor amputation, and survival, was not significantly different between MS and non-MS patients; however, the incidence of minor amputation was significantly higher in diabetic than in non-diabetic patients (42% vs. 17%; p=0.011). Cox regression analysis for the 2-year primary patency demonstrated no association between MS and 2-year primary patency [hazard ratio (HR), 1.02; 95% confidence interval (CI), 0.45-2.30; p=0.961], whereas there was a significant association between diabetes and 2-year primary patency (HR, 2.81; 95% CI, 1.02-7.72; p=0.046). Kaplan-Meier analysis revealed no significant difference in the 2-year primary patency between MS and non-MS patients; however, the 2-year primary patency was lower in diabetic than in non-diabetic patients (p=0.038). CONCLUSION: As a prognostic concept, MS might conceal the adverse impact of diabetes on the prognosis of CLI patients treated with PTA.

BACKGROUND/AIMS: To review the cases of surgically-treated intrahepatic cholangiocarcinoma, and to evaluate the clinical and pathologic features of intrahepatic cholangiocarcinoma that may affect longterm survival among Korean patients. MATERIALS AND METHODS: From 1990 to 1997, 28 patients with intrahepatic cholangiocarcinoma underwent laparotomy. Among them, resection was performed in 25 patients and wedge resection in only 3 patients. The liver resections included: 5 right lobectomies, 1 right trisegmentectomy, 7 left lobectomies, 3 extended left lobectomies, 2 hepatopancreatoduodenectomies and 7 segmentectomies. Curative resection was performed on 15 patients. The histological sections of all resected specimens were immunohistochemically stained with p53 and Ki-67 monoclonal antibodies to assess biological behavior of the tumor cells. The cumulative survival rate and clinicopathological factors, including biological markers (p53, Ki-67), that may influence prognosis were analyzed stastistically. RESULTS: The patients undergoing curative resection survived significantly longer than the patients undergoing noncurative resection. The median survival time for patients with curative resection was 24 months (mean, 34+/-8 months) with 1-, 2-, and 3-year survival rates of 66.6%, 44.4%, and 35.6%, respectively. The median survival time for patients with noncurative resection was 3 months (mean, 8+/-3 months) with 1- and 2-year survival rates of 26.7% and 13.4%, respectively. Univariate analysis showed that positive regional lymph node significantly correlated with poor prognosis (p=0.004); and that curative resection significantly correlated with better prognosis (p=0.001). Age, sex, tumor size, the degree of cell differentiation, gross type of tumor, and p53 and Ki-67 labeling index had no significant correlation with prognosis. CONCLUSION: Our results support the idea that an aggressive liver resection along with regional lymph node dissection is recommended for long-term survival. The validity of the molecular biologic tumor markers (p53, Ki -67) as a prognostic factor is not yet clearly defined.

Transformation and progression of breast cancer are thought to be caused by an accumulation of complex genetic alterations, but little is known about specific changes. In this study, the author has undertaken a genome-wide screening to detect genetic changes in 20 cases of breast cancer among Koreans, including 16 infiltrating ductal carcinomas, 2 medullary carcinomas, 1 invasive lobular carcinoma, and 1 borderline phyllodes tumor. Comparative genomic hybridization (CGH) was used to screen for DNA sequence gains and losses across all human chromosomes. Simultaneous immunohistochemical staining for c-erbB-2 (Her-2/neu), c-myc, cyclin D1, and p53 protein was done to make comparisons with nuclear grade and that with CGH results. Biotin-labeled tumor DNA and digoxigenin-labeled normal DNA were hybridized to normal metaphase cells. The fluorescence signals were captured by fluorescence microscope after detection by avidin-FITC and anti-digoxigenin rhodamine. Then, the ratio of fluorescence was calculated by an image analyzer. The immunohistochemical staining was done in paraffin-embedded tissue with an LSAB kit and avidin-biotin complex (ABC) method. The CGH results showed gains on chromosomes 8q (40%), 1q (30%), 17q (15%), 20q (15%), 18q (15%), 5p (15%), and 13q (15%). Deletions were on chromosomes 17p (45%) and 22q (20%). High-level amplifications (green/red ratio >1.5) were noted on chromosomes 1p31, 1q, 3q25-qter, 5p, 7q31-qter, 8q, 9p22-qter, 10p, 11p, 11q22-qter, 12p, 12q24, 14q21-qter, 15q23-qter, 17q, 18p, 18q12-qter, 20p, and 20q. By comparison with infiltrating ductal carcinoma, the two medullary carcinomas showed high-level amplification on chromosomes 1p31, 1q, 8q, 10p, 11p and 12p. c-erbB-2, c-myc, cyclin D1, and p53 protein expression was immunohistochemically detected in 9 of 20 (45%), 8 of 20 (40%), 10 of 20 (50%), and 13 of 20 (65%), respectively. The results indicate that the amplification on chromosome 8q, 1q and the deletions on chromosomes 17p and 22q are the most frequent genetic alterations in breast cancers among Koreans. The results reveal a different pattern of genetic alteration from previous studies. The CGH results were not correlated with the immunohistochemical profiles. The amplification pattern of medullary carcinomas was quite different from the pattern of infiltrating ductal carcinomas. The CGH was thought to be very useful in the screening of genetic alterations of solid tumors.
